00:02:18.090 --> 00:02:20.860 this is a quote by Paul, "it would be nice 00:02:20.860 --> 00:02:23.330 if I can bring my way of a cup of coffee. 00:02:23.330 --> 00:02:24.360 Wouldn't that be nice?" 00:02:24.360 --> 00:02:26.235 And we think, yeah, so this is the problem we 00:02:26.235 --> 00:02:27.570 that ended up pursuing. 00:02:27.570 --> 00:02:31.792 And then we dove into the context of this problem more. 00:02:31.792 --> 00:02:33.500 So looking at it from a few perspectives, 00:02:33.500 --> 00:02:35.570 so culturally he doesn't want to use a wheelchair. 00:02:35.570 --> 00:02:37.278 Like I said, he had a hip problem before, 00:02:37.278 --> 00:02:39.220 so he had to be on an electric scooter, 00:02:39.220 --> 00:02:41.030 and he actually didn't like that all. 00:02:41.030 --> 00:02:41.675 He wants to use crutches. 00:02:41.675 --> 00:02:42.930 He wants to be able to stand. 00:02:42.930 --> 00:02:45.590 But because of the nature of his injury, 00:02:45.590 --> 00:02:48.480 he couldn't use prosthetics, so he had to use crutches. 00:02:48.480 --> 00:02:50.761 And socially his wife helps him with many activities, 00:02:50.761 --> 00:02:52.010 including bringing him coffee. 00:02:52.010 --> 00:02:54.610 But his wife does have work, so he needs to do this 00:02:54.610 --> 00:02:56.580 by himself when he's at home. 00:02:56.580 --> 00:02:59.210 And physically he just wants to do this in his apartment. 00:02:59.210 --> 00:03:01.085 When he brews a cup of coffee in the morning. 00:03:01.085 --> 00:03:03.780 He wants to be able to carry it to the living room, 00:03:03.780 --> 00:03:05.113 something like simple like that. 00:03:10.110 --> 00:03:12.340 And looking at it one statement, so this 00:03:12.340 --> 00:03:15.190 is our problem statement-- a design, 00:03:15.190 --> 00:03:19.770 a mechanism, that help him carry a cup of coffee around his home 00:03:19.770 --> 00:03:21.690 without spilling, and such that he 00:03:21.690 --> 00:03:23.130 doesn't have to grab onto it. 00:03:23.130 --> 00:03:25.100 And this is the way he carries it right now. 00:03:25.100 --> 00:03:27.032 It's kind of a grip and then while trying 00:03:27.032 --> 00:03:29.240 to use crutches at the same time, so you can imagine, 00:03:29.240 --> 00:03:30.530 it's really tough. 00:03:30.530 --> 00:03:32.870 And we kind of break it down to two main problems, which 00:03:32.870 --> 00:03:35.562 is how do we do it hands-free, so he doesn't have to hold it, 00:03:35.562 --> 00:03:37.770 and how do we do no-spill, so he doesn't spill coffee 00:03:37.770 --> 00:03:39.320 on his hands. 00:03:39.320 --> 00:03:44.380 And I'll let Lexi talk about the success metrics. 00:03:44.380 --> 00:03:47.620 LEXI DIEN: So right now, basically, Paul 00:03:47.620 --> 00:03:51.430 can carry a cup of coffee around with that claw grip, 00:03:51.430 --> 00:03:53.080 and he can only fill it about a third 00:03:53.080 --> 00:03:55.450 full if he doesn't want to spill it all over his hands 00:03:55.450 --> 00:03:57.260 or on the floor. 00:03:57.260 --> 00:04:02.210 We'd like to make that a larger amount of coffee, 00:04:02.210 --> 00:04:05.600 and we'd like to make sure that it isn't spilled. 00:04:05.600 --> 00:04:09.896 So for a livable goal we decided that maybe the coffee 00:04:09.896 --> 00:04:13.940 would be 2/3 full and he could not spill it. 00:04:13.940 --> 00:04:15.610 And then as an ambitious goal, we 00:04:15.610 --> 00:04:19.930 would say 3/4 full and also no spill. 00:04:19.930 --> 00:04:21.779 Some other additional things we talked about 00:04:21.779 --> 00:04:24.550 were making it easy to remove from his crutch 00:04:24.550 --> 00:04:28.795 or from whatever it is; the technology is just 00:04:28.795 --> 00:04:32.500 easy to use and take away. 00:04:32.500 --> 00:04:36.190 And so we said 20 seconds for a livable and then 10 seconds 00:04:36.190 --> 00:04:36.820 preferably. 00:04:36.820 --> 00:04:40.360 We want it to be as quick possible. 00:04:40.360 --> 00:04:42.080 We also decided that we wanted to take 00:04:42.080 --> 00:04:44.180 Paul's perspective into this. 00:04:44.180 --> 00:04:46.060 I think that's very important. 00:04:46.060 --> 00:04:47.860 We wanted, especially, him to rate 00:04:47.860 --> 00:04:52.420 it, and we're hoping ambitiously to get an 8 out of 10. 00:04:52.420 --> 00:04:55.260 More livably, we think a 6 out of 10 00:04:55.260 --> 00:04:57.240 will be something that we'd accept, 00:04:57.240 --> 00:05:01.360 but we really want to get as high as possible on his rating. 00:05:01.360 --> 00:05:06.060 And the last thing we wanted to make sure 00:05:06.060 --> 00:05:10.400 is that we actually are able to use it with a mug. 00:05:10.400 --> 00:05:15.060 He uses his own mugs, and wants to be able to use his own mugs. 00:05:15.060 --> 00:05:18.710 So we want to make sure that it works for at least that mug, 00:05:18.710 --> 00:05:22.870 and preferably it works for a lot of his mugs 00:05:22.870 --> 00:05:26.190 or all of his mugs. 00:05:26.190 --> 00:05:30.600 So we're going to show you the video that we put together 00:05:30.600 --> 00:05:33.271 that gives you a little bit more background into Paul. 00:05:33.271 --> 00:05:40.150 [VIDEO PLAYBACK] 00:05:40.150 --> 00:05:42.109 -You know, it would be just nice if I could 00:05:42.109 --> 00:05:44.173 bring my wife cup of coffee. 00:05:44.173 --> 00:05:45.423 I mean, wouldn't that be nice? 00:05:50.110 --> 00:05:53.020 My name's Paul [? Nershimski. ?] I'm 62 years old. 00:05:53.020 --> 00:05:57.180 I've been disabled since I was 24. 00:05:57.180 --> 00:06:01.520 -Paul uses forearm crutches because his imputation 00:06:01.520 --> 00:06:05.000 doesn't allow for a prosthetic. 00:06:05.000 --> 00:06:08.180 Despite the fact that his forearm crutches don't really 00:06:08.180 --> 00:06:11.540 let him carry things while he's walking, for Paul, 00:06:11.540 --> 00:06:13.240 the most important thing is to be 00:06:13.240 --> 00:06:16.975 able to move around and go places. 00:06:16.975 --> 00:06:19.720 -And one the big dreams of my life 00:06:19.720 --> 00:06:21.936 has been to be able to carry around a coffee 00:06:21.936 --> 00:06:25.335 cup around the house like a normal human 00:06:25.335 --> 00:06:28.430 being with burning my fingers and ruining the rug. 00:06:28.430 --> 00:06:31.900 -What really drew me to Paul was just the very simple nature 00:06:31.900 --> 00:06:34.910 of what he wanted, something that you and I take 00:06:34.910 --> 00:06:40.070 for granted, just the ability to transport food and even just 00:06:40.070 --> 00:06:42.735 a cup of coffee from his crutches to his living room 00:06:42.735 --> 00:06:46.150 without spilling it all over his floor. 00:06:46.150 --> 00:06:49.446 -Cup full of water, not far from the brim, 00:06:49.446 --> 00:06:52.220 I would have to carry it like that, with my hand wrapped 00:06:52.220 --> 00:06:53.400 around the crutch handle. 00:06:53.400 --> 00:06:57.240 And maybe you can realized that would be a horror show. 00:06:57.240 --> 00:06:59.140 -He wants to carry a cup of coffee 00:06:59.140 --> 00:07:03.380 around without burning himself, and that's very, very different 00:07:03.380 --> 00:07:06.167 from other people, other clients, had in mind. 00:07:06.167 --> 00:07:07.625 But this project's very mechanical. 00:07:07.625 --> 00:07:10.476 It' very simple, yet a really challenging problem. 00:07:10.476 --> 00:07:12.690 -That may seem like not much to most people, 00:07:12.690 --> 00:07:13.620 but it's huge to me. 00:07:17.958 --> 00:07:20.010 -There are many, many ideas floating around, 00:07:20.010 --> 00:07:23.150 but one of them is a gyroscope, something 00:07:23.150 --> 00:07:24.780 that would with the gyroscopic motion 00:07:24.780 --> 00:07:29.234 that can keep the coffee level while he's with his crutches. 00:07:29.234 --> 00:07:32.010 And this is one of the designs that we 00:07:32.010 --> 00:07:38.460 saw online that kind of resembles what we want to have. 00:07:38.460 --> 00:07:40.174 It's basically a cup holder that allows 00:07:40.174 --> 00:07:42.590 motion, that allows it to stay level when there is motion. 00:07:46.900 --> 00:07:52.345 -There's a kind of silicon cover that goes over the coffee mug, 00:07:52.345 --> 00:07:55.305 and if it gets a good seal, then it works really, really well. 00:07:57.530 --> 00:08:03.060 -Silicone cover does wonders-- nothing. 00:08:03.060 --> 00:08:04.469 [LAUGHTER] 00:08:04.469 --> 00:08:05.635 -So you have water in there? 00:08:05.635 --> 00:08:09.030 -Yeah, it's pretty full. 00:08:09.030 --> 00:08:10.485 -Wow, that's great. 00:08:10.485 --> 00:08:11.455 -That really works. 00:08:11.455 --> 00:08:13.360 I mean, that's full. 00:08:13.360 --> 00:08:16.465 I try no to over think things, get like a real simple thing 00:08:16.465 --> 00:08:18.910 that I couldn't do. 00:08:18.910 --> 00:08:21.160 And you're making it so I'm going to be able to do it. 00:08:26.374 --> 00:08:29.220 [END PLAYBACK] 00:08:29.220 --> 00:08:30.960 LEXI DIEN: So, as you saw in the video, 00:08:30.960 --> 00:08:33.165 we've been trying out a lot of different prototypes 00:08:33.165 --> 00:08:38.390 with Paul, mainly things that we found online, 00:08:38.390 --> 00:08:43.630 some things like this on-stage cup holder, which is basically 00:08:43.630 --> 00:08:46.850 a cup holder that can statically be just clicked 00:08:46.850 --> 00:08:53.770 on to his crutch, and it doesn't help tipping at all, 00:08:53.770 --> 00:08:58.890 so if it was an open cup, it would just pour out. 00:08:58.890 --> 00:09:02.690 But it's something that helps the hands-free aspect. 00:09:02.690 --> 00:09:06.020 And something like the water bottle holder 00:09:06.020 --> 00:09:08.740 would also do this maybe, except for it might not 00:09:08.740 --> 00:09:10.800 fit a mug very well. 00:09:10.800 --> 00:09:16.700 So right now we're looking into some snap-on clamps, 00:09:16.700 --> 00:09:19.250 like this one. 00:09:19.250 --> 00:09:23.330 It would just be easy to snap on and off of his crutch 00:09:23.330 --> 00:09:29.040 so that he could take it off and on the crutch 00:09:29.040 --> 00:09:31.160 very easily and very quickly. 00:09:31.160 --> 00:09:32.535 So I'm going to pass these around 00:09:32.535 --> 00:09:35.910 for people to look at it. 00:09:35.910 --> 00:09:39.830 Some ideas for the no-spill solution-- as you 00:09:39.830 --> 00:09:42.370 saw, we were thinking gyroscope maybe. 00:09:42.370 --> 00:09:44.950 It turns out that that's a little bit more complicated 00:09:44.950 --> 00:09:47.300 than we thought it would be. 00:09:47.300 --> 00:09:49.200 It's a little touchy. 00:09:49.200 --> 00:09:52.250 So we're trying to look a little bit in a different way. 00:09:52.250 --> 00:09:55.860 The second thing we did was the CoverFlex, 00:09:55.860 --> 00:09:57.209 which we showed in the video. 00:09:57.209 --> 00:09:59.500 It takes a little bit of time to put on and off though, 00:09:59.500 --> 00:10:03.370 so we were looking into some other ways, which one of them 00:10:03.370 --> 00:10:04.730 is this suction cover. 00:10:07.310 --> 00:10:10.950 So this is a mug, very easy. 00:10:10.950 --> 00:10:12.843 I'm going to pour some water into it 00:10:12.843 --> 00:10:20.340 and then put one of these section covers on top of it, 00:10:20.340 --> 00:10:23.200 and no water will spill out. 00:10:23.200 --> 00:10:26.060 So we're hoping that this will be able to work for his mugs 00:10:26.060 --> 00:10:29.180 as well, and work on that a little bit. 00:10:29.180 --> 00:10:33.100 Another thing that we're looking into, which is coming in today, 00:10:33.100 --> 00:10:37.190 is this Spill-Not, which is a device that's specifically 00:10:37.190 --> 00:10:40.290 made to counteract movement. 00:10:40.290 --> 00:10:42.370 When you place a mug on it, basically, that 00:10:42.370 --> 00:10:47.070 would make it so that it wouldn't spill hopefully. 00:10:47.070 --> 00:10:49.000 So we're looking into that a little bit more. 00:10:56.817 --> 00:10:58.400 BRADY ENSTAD: So at our client meaning 00:10:58.400 --> 00:10:59.941 for the first prototype, like I said, 00:10:59.941 --> 00:11:04.320 we showed Paul the on-stage microphone clip, 00:11:04.320 --> 00:11:08.500 and we showed him the CoverFlex silicon cover, 00:11:08.500 --> 00:11:10.450 and we left those with him this past week, 00:11:10.450 --> 00:11:14.600 and we're going to go back on Wednesday after class 00:11:14.600 --> 00:11:16.970 and get is feedback on those. 00:11:16.970 --> 00:11:19.210 He was actually more excited because we told him 00:11:19.210 --> 00:11:20.770 that the Spill-Not was coming. 00:11:20.770 --> 00:11:23.649 He was more excited about that than anything else. 00:11:23.649 --> 00:11:25.440 But the CoverFlex, as you saw in the video, 00:11:25.440 --> 00:11:28.300 actually worked really, really well. 00:11:28.300 --> 00:11:32.190 The only difficulty with it is that once you have it 00:11:32.190 --> 00:11:34.209 on and take it off, like if there's 00:11:34.209 --> 00:11:36.250 been any spillage at all, it's a little difficult 00:11:36.250 --> 00:11:38.930 to get it back on again, which is why we decided to go 00:11:38.930 --> 00:11:41.240 with these suction covers. 00:11:41.240 --> 00:11:43.932 The only problem with those is they might not fit his mugs. 00:11:43.932 --> 00:11:45.390 So there's a possibility that we'll 00:11:45.390 --> 00:11:49.120 have to do a little bit more shopping around 00:11:49.120 --> 00:11:52.880 to find larger covers that will probably fit his mugs. 00:11:52.880 --> 00:11:57.920 That's honestly the biggest problem is his mugs are huge. 00:11:57.920 --> 00:12:01.880 So coffee addict, or something, but yeah, 00:12:01.880 --> 00:12:05.390 like I said he's super, duper excited about the Spill-Not. 00:12:05.390 --> 00:12:08.540 And honestly one of our biggest visions 00:12:08.540 --> 00:12:10.942 for what will end up happening is 00:12:10.942 --> 00:12:12.900 that we'll be able to incorporate the Spill-Not 00:12:12.900 --> 00:12:15.220 with a quick on-and-off clamp, like the one that's 00:12:15.220 --> 00:12:15.970 going around. 00:12:18.750 --> 00:12:22.535 Like I said, the clamp, it works really well on-stage, 00:12:22.535 --> 00:12:24.160 but it doesn't really prevent spilling, 00:12:24.160 --> 00:12:27.780 and it's pretty slow because it's a screw-on/screw-off type 00:12:27.780 --> 00:12:31.750 mechanism, as opposed to just a quick clamp. 00:12:31.750 --> 00:12:33.770 He liked the CoverFlex, but if there's 00:12:33.770 --> 00:12:36.480 something that's easier, like those suction covers, 00:12:36.480 --> 00:12:38.140 then he would prefer that. 00:12:38.140 --> 00:12:41.570 So for future work, as I said, we're 00:12:41.570 --> 00:12:45.440 going to be testing more off-the-shell prototypes, 00:12:45.440 --> 00:12:48.010 different suction mug covers maybe. 00:12:48.010 --> 00:12:50.160 The bike cup holder, we haven't entirely 00:12:50.160 --> 00:12:52.326 abandoned that idea yet either. 00:12:52.326 --> 00:12:53.700 And then obviously, the Spill-Not 00:12:53.700 --> 00:12:55.075 is what we're most excited about. 00:12:56.752 --> 00:12:58.460 We're going to go get feedback from Paul. 00:12:58.460 --> 00:13:01.602 And if he has some feedback for us 00:13:01.602 --> 00:13:03.810 that we can't meet with any off-the-shelf prototypes, 00:13:03.810 --> 00:13:05.920 then we're just going to do some customization 00:13:05.920 --> 00:13:08.350 for his final prototype. 00:13:08.350 --> 00:13:09.850 PROFESSOR: So first of all, you guys 00:13:09.850 --> 00:13:13.440 have scoped this really well, in the sense that this is a really 00:13:13.440 --> 00:13:18.410 well-defined problem that you've worked out with Paul. 00:13:18.410 --> 00:13:22.960 And it seems like you're finding a lot of pieces 00:13:22.960 --> 00:13:25.940 to the solution that are already out there, that maybe you 00:13:25.940 --> 00:13:30.080 can combine to make something that's really good for him. 00:13:30.080 --> 00:13:33.555 So I would encourage you, or have you thought about-- let 00:13:33.555 --> 00:13:35.610 me phrase this as a question. 00:13:35.610 --> 00:13:38.170 Have you thought about the sustainability 00:13:38.170 --> 00:13:39.180 of your solution? 00:13:39.180 --> 00:13:44.170 So these cover flex things, for example, how do they fail? 00:13:44.170 --> 00:13:47.210 And how will things break? 00:13:47.210 --> 00:13:49.450 And what is going to have to replace? 00:13:49.450 --> 00:13:51.360 And sort of what is the lifetime of what 00:13:51.360 --> 00:13:52.984 you're building for him? 00:13:52.984 --> 00:13:55.150 BRADY ENSTAD: So the great thing about the CoverFlex 00:13:55.150 --> 00:13:58.730 is that it's actually oven and dishwasher safe. 00:13:58.730 --> 00:14:03.100 So presumably, it's got a relatively long life cycle, 00:14:03.100 --> 00:14:07.250 and we're thinking, honestly, on the order of, hopefully, 00:14:07.250 --> 00:14:12.400 years because it is oven and dishwasher safe, 00:14:12.400 --> 00:14:15.030 unless he somehow super-duper heats it beyond what it's rated 00:14:15.030 --> 00:14:16.696 for, which I don't really know how you'd 00:14:16.696 --> 00:14:20.230 do that because it's oven safe. 00:14:20.230 --> 00:14:26.387 And as far as the clamp, the hands-free solution goes, 00:14:26.387 --> 00:14:28.095 frankly it's a purely mechanical systems. 00:14:28.095 --> 00:14:31.340 So unless he finds some way to snap off 00:14:31.340 --> 00:14:35.100 the clamp, which it could happen, don't get me wrong, 00:14:35.100 --> 00:14:37.900 but the great thing about these components that we found 00:14:37.900 --> 00:14:39.900 is that they're actually relatively inexpensive. 00:14:39.900 --> 00:14:44.120 And so the idea we have is that after the class 00:14:44.120 --> 00:14:46.880 is over we would leave him with these part numbers. 00:14:46.880 --> 00:14:49.210 Because he has a computer at home-- he's tech savvy. 00:14:49.210 --> 00:14:53.400 He used to work in IT-- so if something were to break, 00:14:53.400 --> 00:14:55.990 he could just purchased himself another one, 00:14:55.990 --> 00:14:59.990 assuming that there's not a great deal of customization 00:14:59.990 --> 00:15:01.080 that goes into it. 00:15:01.080 --> 00:15:04.620 And we don't actually know the scope of customization that's 00:15:04.620 --> 00:15:07.622 going to have to go into it just yet because, as I said, 00:15:07.622 --> 00:15:09.580 what we're most excited about is the Spill-Not, 00:15:09.580 --> 00:15:11.080 and we're not really sure how that's 00:15:11.080 --> 00:15:15.029 going to be incorporated with the clamp just yet. 00:15:15.029 --> 00:15:16.945 PROFESSOR 2: So I would just kind of encourage 00:15:16.945 --> 00:15:19.111 as you're thinking about the failure modes, not just 00:15:19.111 --> 00:15:20.980 the individual failure modes, but kind 00:15:20.980 --> 00:15:23.130 of the cross-coupled failure modes-- 00:15:23.130 --> 00:15:26.110 as I was looking at the seal, one of the ways 00:15:26.110 --> 00:15:29.550 that you release the seal is by kind of flipping that edge, 00:15:29.550 --> 00:15:32.230 so you want to be careful that that edge isn't actually 00:15:32.230 --> 00:15:34.660 going to be affected by whatever your mechanism is 00:15:34.660 --> 00:15:35.636 for holding it. 00:15:35.636 --> 00:15:37.260 So think about the kind of the coupling 00:15:37.260 --> 00:15:39.115 that you get between your solutions, 00:15:39.115 --> 00:15:42.780 and not just the independent issues that you have with them. 00:15:42.780 --> 00:15:45.530 One of the questions that I had for you was regarding 00:15:45.530 --> 00:15:48.610 your performance metrics, how you selected those on/off 00:15:48.610 --> 00:15:51.280 times, and how that related to his function 00:15:51.280 --> 00:15:54.920 versus the mechanical structure itself? 00:15:54.920 --> 00:15:57.670 And kind of from looking at some of your video, 00:15:57.670 --> 00:15:59.960 I'm wondering-- I couldn't really 00:15:59.960 --> 00:16:04.090 tell if he had any additional tremors or other issues 00:16:04.090 --> 00:16:06.000 as well that might affect his function that 00:16:06.000 --> 00:16:07.160 might affect that timing. 00:16:07.160 --> 00:16:09.950 So if you could just talk on that generation of timing? 00:16:09.950 --> 00:16:13.890 BRADY ENSTAD: Yeah, sure, so honestly, we just asked Paul. 00:16:13.890 --> 00:16:17.480 We said, Paul, how quickly do you want this thing be put on 00:16:17.480 --> 00:16:19.090 and be taken off? 00:16:19.090 --> 00:16:21.720 And he said, well, relatively quickly, 00:16:21.720 --> 00:16:23.710 and he wouldn't give us a solid number. 00:16:23.710 --> 00:16:26.260 So we were just like, OK, you know, 00:16:26.260 --> 00:16:29.030 20 seconds is a little long. 00:16:29.030 --> 00:16:31.470 10 seconds seems like a reasonable time. 00:16:31.470 --> 00:16:34.770 The great thing about Paul is the only disability 00:16:34.770 --> 00:16:37.470 that he has is the fact that his leg is amputated. 00:16:37.470 --> 00:16:40.980 So doesn't have any tremors or anything 00:16:40.980 --> 00:16:43.320 else, any other sort of disability. 00:16:43.320 --> 00:16:47.930 So I mean, as we talked about actually in lecture 00:16:47.930 --> 00:16:49.890 earlier today, it's possible as he gets older, 00:16:49.890 --> 00:16:52.672 those hands might start shaking and that sort of thing. 00:16:52.672 --> 00:16:54.880 But that's actually why we're excited about the clamp 00:16:54.880 --> 00:16:56.840 is because there's less precision involved. 00:16:56.840 --> 00:16:59.446 It's just a pretty simple snapping motion. 00:17:02.410 --> 00:17:04.260 So as far as like generating those numbers, 00:17:04.260 --> 00:17:07.030 it was just basically a kind of a general feeling 00:17:07.030 --> 00:17:10.730 we got from Paul, and we went with, well, 00:17:10.730 --> 00:17:12.670 what do you think about these numbers? 00:17:12.670 --> 00:17:14.800 And the great thing about Paul is also 00:17:14.800 --> 00:17:18.160 one of the worst things he's incredibly laid back, 00:17:18.160 --> 00:17:21.890 so he wasn't particularly zealous about giving 00:17:21.890 --> 00:17:23.170 us had numbers. 00:17:23.170 --> 00:17:24.760 So he was pretty willing to along 00:17:24.760 --> 00:17:25.710 with anything that we suggested. 00:17:25.710 --> 00:17:28.251 PROFESSOR 2: What are ways that you think that you guys might 00:17:28.251 --> 00:17:30.730 be able to validate those numbers a little bit more 00:17:30.730 --> 00:17:32.480 as you keep going and looking at some 00:17:32.480 --> 00:17:34.340 of these different designs? 00:17:34.340 --> 00:17:38.880 BRADY ENSTAD: Sure, so if you take a look at the clamp, 00:17:38.880 --> 00:17:40.880 between positioning it and snapping it, 00:17:40.880 --> 00:17:43.820 I think you're probably looking at realistically probably 00:17:43.820 --> 00:17:45.090 less than five seconds. 00:17:45.090 --> 00:17:50.570 It's not real picky about where you put it on the crutch. 00:17:50.570 --> 00:17:52.940 So obviously, we're just going to keep 00:17:52.940 --> 00:17:56.450 adjusting those numbers as what's 00:17:56.450 --> 00:17:59.937 realistic becomes more apparent. 00:17:59.937 --> 00:18:01.770 Like I said, we don't really know the degree 00:18:01.770 --> 00:18:04.480 of customization we're going to have to go to yet, especially 00:18:04.480 --> 00:18:08.120 if we're going to incorporate the Spill-Not. 00:18:08.120 --> 00:18:11.265 So once we get that and we do a little bit more prototyping, 00:18:11.265 --> 00:18:13.820 I'd be able to give you more solid answer for that. 00:18:13.820 --> 00:18:17.800 But as of right now, we don't really know. 00:18:17.800 --> 00:18:20.050 PROFESSOR 3: I am a coffee aficionado, 00:18:20.050 --> 00:18:24.097 and I just am OCD about the cup that I have. 00:18:24.097 --> 00:18:27.610 I have two or three mugs that I just love. 00:18:27.610 --> 00:18:31.090 I can press the Keurig twice, and it fills it up just right. 00:18:31.090 --> 00:18:32.080 So I get that. 00:18:32.080 --> 00:18:34.320 But I'm wondering, have you talked 00:18:34.320 --> 00:18:37.830 with this gentleman about his ability or willingness 00:18:37.830 --> 00:18:39.240 to negotiate? 00:18:39.240 --> 00:18:43.330 To me, one of the obvious solutions 00:18:43.330 --> 00:18:47.060 would be to have-- because he has good hand function, 00:18:47.060 --> 00:18:51.300 presumably-- is to fill up a thermos mug 00:18:51.300 --> 00:18:55.050 and have a simple clip that you can put on his foreleg 00:18:55.050 --> 00:18:58.320 crutches, walk to a table, and pour the coffee 00:18:58.320 --> 00:19:01.805 into his delightful cup. 00:19:01.805 --> 00:19:04.430 BRADY ENSTAD: So that's actually one of the very first thoughts 00:19:04.430 --> 00:19:06.780 that we had, and we asked Paul about that. 00:19:06.780 --> 00:19:10.100 And his reply honestly surprised us a little bit. 00:19:10.100 --> 00:19:12.990 He's not honestly concerned about carrying 00:19:12.990 --> 00:19:15.340 the cup of coffee so much for himself, 00:19:15.340 --> 00:19:17.830 as it is that he wants to help his wife out. 00:19:17.830 --> 00:19:21.590 Because while he was stuck in the wheelchair, he was really, 00:19:21.590 --> 00:19:23.500 really reliant on her, and so he wants 00:19:23.500 --> 00:19:26.536 to be able to carry a cup of coffee for his wife. 00:19:26.536 --> 00:19:27.910 And his whole thing about that is 00:19:27.910 --> 00:19:29.840 that I want to be able to carry it in the mug 00:19:29.840 --> 00:19:32.320 and just give it to her, and I don't 00:19:32.320 --> 00:19:36.182 want have to pour it out at the table or anything like that. 00:19:36.182 --> 00:19:38.598 PROFESSOR 4: One or two quick questions from the audience. 00:19:41.311 --> 00:19:43.977 AUDIENCE: So his Paul willing to have something on his crutches, 00:19:43.977 --> 00:19:48.097 or is that [INAUDIBLE], like the [INAUDIBLE]? 00:19:48.097 --> 00:19:50.680 BRADY ENSTAD: So that's why we were talking about quick on/off 00:19:50.680 --> 00:19:53.800 times, and the answer to that is, no, not really. 00:19:53.800 --> 00:19:56.860 He's OK with using it for the short period of time 00:19:56.860 --> 00:19:59.260 that it takes to transport the cup of coffee. 00:19:59.260 --> 00:20:00.760 But once he gets to the couch, he 00:20:00.760 --> 00:20:03.515 wants to be able to take it off because the way 00:20:03.515 --> 00:20:05.640 that he stores his crutches when he's sitting down, 00:20:05.640 --> 00:20:08.270 is he puts them on the floor. 00:20:08.270 --> 00:20:10.930 And so if there's anything attached to them 00:20:10.930 --> 00:20:13.880 that might possibly get in the way was his concerned. 00:20:13.880 --> 00:20:15.980 So the quicker on/off time, the better. 00:20:17.507 --> 00:20:19.132 PROFESSOR 4: [INAUDIBLE] last question, 00:20:19.132 --> 00:20:21.800 then we can have Team Margaret also begin to set up as well. 00:20:21.800 --> 00:20:23.883 PROFESSOR 3: The other quick thing I wanted to ask 00:20:23.883 --> 00:20:26.480 is, have you consulted an occupational therapist 00:20:26.480 --> 00:20:30.930 at all, someone who deals with these kinds of approaches 00:20:30.930 --> 00:20:32.890 on a daily basis? 00:20:32.890 --> 00:20:38.220 There might be some other simple solution that-- or maybe not so 00:20:38.220 --> 00:20:40.280 simple solution, but an established 00:20:40.280 --> 00:20:43.890 solution that someone has already dealt with. 00:20:43.890 --> 00:20:47.420 Because obviously, amputation and this kind of injury 00:20:47.420 --> 00:20:50.000 is fairly common and ubiquitous. 00:20:50.000 --> 00:20:52.340 BRADY ENSTAD: And the answer to that is, no, we haven't. 00:20:52.340 --> 00:20:53.930 But that sounds like a really great idea, 00:20:53.930 --> 00:20:54.950 so we'll look into that. 00:21:00.384 --> 00:21:01.372 PROFESSOR 4: Thank you. 00:21:01.372 --> 00:21:02.247 BRADY ENSTAD: Thanks. 00:21:08.439 --> 00:21:09.730 TANYA TALKAR: So, hi, everyone. 00:21:09.730 --> 00:21:11.080 We're Team Margaret. 00:21:11.080 --> 00:21:11.825 I'm Tanya. 00:21:11.825 --> 00:21:13.254 LAURA D'AQUILA: I'm Laura. 00:21:13.254 --> 00:21:14.920 TANYA TALKAR: And Beth his third member, 00:21:14.920 --> 00:21:18.980 but she's unable to get make it to the presentation today. 00:21:18.980 --> 00:21:20.039 So this is the team. 00:21:20.039 --> 00:21:22.330 I think we might have shown you this picture last week, 00:21:22.330 --> 00:21:24.927 but this is Margaret, our client. 00:21:24.927 --> 00:21:26.510 Interesting story about this picture-- 00:21:26.510 --> 00:21:28.093 she was actually the one who suggested 00:21:28.093 --> 00:21:30.370 that we take a selfie. 00:21:30.370 --> 00:21:32.510 So she's a great person. 00:21:32.510 --> 00:21:34.562 So a little bit about her as a person. 00:21:34.562 --> 00:21:37.020 She is an artist, so she loves to paint, loves to make arts 00:21:37.020 --> 00:21:37.519 and crafts. 00:21:37.519 --> 00:21:40.100 Her room is filled with a bunch of crafts. 00:21:40.100 --> 00:21:42.350 She's also an advocate, so she's on the Safety Council 00:21:42.350 --> 00:21:44.141 for The Boston Home, which means that she's 00:21:44.141 --> 00:21:46.450 talking a lot with residents to make sure that they are 00:21:46.450 --> 00:21:50.080 comfortable with their position at The Boston Home 00:21:50.080 --> 00:21:51.390 and everything that's going on. 00:21:51.390 --> 00:21:54.017 And Laura will talk a little bit about The Boston Home. 00:21:54.017 --> 00:21:54.850 She's also a friend. 00:21:54.850 --> 00:21:58.060 She FaceTimes a lot on her iPad with friends and family, 00:21:58.060 --> 00:22:00.310 And she's an immensely helpful mentor, 00:22:00.310 --> 00:22:02.445 not only to us, but also all of the other residents 00:22:02.445 --> 00:22:04.800 of the Boston Home. 00:22:04.800 --> 00:22:06.740 So about her disability-- she was 00:22:06.740 --> 00:22:08.660 diagnosed with multiple sclerosis, 00:22:08.660 --> 00:22:11.590 and she decided on her own to live at The Boston Home. 00:22:11.590 --> 00:22:13.220 So she has been at The Boston Home 00:22:13.220 --> 00:22:17.321 for about eight years, gotten during admission process. 00:22:17.321 --> 00:22:19.070 She gets around on a motorized wheelchair. 00:22:19.070 --> 00:22:20.970 All of the resonance have wheelchairs, 00:22:20.970 --> 00:22:22.410 and she's relatively independent. 00:22:22.410 --> 00:22:26.560 She has some fatigue in terms of trying to sign documents, 00:22:26.560 --> 00:22:29.255 or after using her iPad for a while, she will get fatigued, 00:22:29.255 --> 00:22:31.110 and her fingers will drag. 00:22:31.110 --> 00:22:33.050 But she is still relatively independent. 00:22:33.050 --> 00:22:35.950 And she was a social worker before she 00:22:35.950 --> 00:22:37.910 came to The Boston Home, which means 00:22:37.910 --> 00:22:40.752 that all of her thoughts and actions are really altruistic. 00:22:40.752 --> 00:22:42.460 She's always thinking about other people. 00:22:45.175 --> 00:22:46.550 LAURA D'AQUILA: So this over here 00:22:46.550 --> 00:22:48.050 is a picture of The Boston Home. 00:22:48.050 --> 00:22:50.180 It's located in Dorchester, Massachusetts. 00:22:50.180 --> 00:22:53.300 And Beth, Tanya, and I go visit it every Friday 00:22:53.300 --> 00:22:55.940 to meet with Margaret, other residents, and staff 00:22:55.940 --> 00:22:57.460 members of the home. 00:22:57.460 --> 00:22:59.390 To tell you a little bit more about the home, 00:22:59.390 --> 00:23:02.570 it was founded in 1881 as a long-term care 00:23:02.570 --> 00:23:05.330 center for adults with multiple sclerosis 00:23:05.330 --> 00:23:11.070 and other progressive neurodegenerative diseases. 00:23:11.070 --> 00:23:14.510 The average resident in The Boston Home is 58 years old, 00:23:14.510 --> 00:23:16.950 and The Boston Home places great emphasis 00:23:16.950 --> 00:23:18.844 on independence of residents. 00:23:18.844 --> 00:23:20.260 So we'll see later on that there's 00:23:20.260 --> 00:23:22.650 a lot of assistive technology that does 00:23:22.650 --> 00:23:24.180 exist within The Boston Home. 00:23:24.180 --> 00:23:29.420 There's 96 residents in the home and approximately 200 staff 00:23:29.420 --> 00:23:30.260 members. 00:23:30.260 --> 00:23:32.750 And it's a really nice place to live. 00:23:32.750 --> 00:23:36.990 They have activities, meetings, other social events, 00:23:36.990 --> 00:23:41.140 and it's known nationally for providing exceptional care 00:23:41.140 --> 00:23:42.035 to residents. 00:23:44.740 --> 00:23:48.020 And this over here is a picture of Don, one of our panelists. 00:23:48.020 --> 00:23:50.320 He's done a lot of great work in the home 00:23:50.320 --> 00:23:53.040 for making sure that residents do have access 00:23:53.040 --> 00:23:54.780 to assistive technology. 00:23:54.780 --> 00:23:58.530 For example, he mounts iPads on the motorized wheelchairs 00:23:58.530 --> 00:23:59.700 of residents. 00:23:59.700 --> 00:24:01.940 He also has a 3D printer that he's 00:24:01.940 --> 00:24:04.690 used to design pieces of assistive technology. 00:24:08.575 --> 00:24:10.366 TANYA TALKAR: So specifically, the activity 00:24:10.366 --> 00:24:13.630 that we've been working with for the past month has 00:24:13.630 --> 00:24:16.470 been the nurse call system or the call light system. 00:24:16.470 --> 00:24:18.890 And so what this is, is that residents, 00:24:18.890 --> 00:24:21.530 if they're in their room, can press a button-- we'll show it 00:24:21.530 --> 00:24:24.370 in a bit-- to call a nurse and call and aide 00:24:24.370 --> 00:24:26.120 to come and help them in their room. 00:24:26.120 --> 00:24:27.860 So there's a wired-in call light system. 00:24:27.860 --> 00:24:30.520 It's a button that it has been wired to the wall, 00:24:30.520 --> 00:24:33.290 and nurses are currently trained to place this button 00:24:33.290 --> 00:24:34.800 in the middle of bed. 00:24:34.800 --> 00:24:36.500 Many times though, it's forgotten about. 00:24:36.500 --> 00:24:38.320 So it's either not placed in the middle of the better, 00:24:38.320 --> 00:24:40.030 or it's placed in an unreachable spot. 00:24:40.030 --> 00:24:42.520 So Margaret sometimes has to come up to a table 00:24:42.520 --> 00:24:44.300 and has to either pull on the wire 00:24:44.300 --> 00:24:47.500 or pull on sheets to try and get the button. 00:24:47.500 --> 00:24:49.610 And there's also just no way of using the system 00:24:49.610 --> 00:24:51.370 if the resident is outside the home. 00:24:51.370 --> 00:24:51.870 So. 00:24:51.870 --> 00:24:54.960 For example, there was a resident who had gone outside, 00:24:54.960 --> 00:24:57.220 got stuck in a ditch, and his wheelchair tipped over, 00:24:57.220 --> 00:25:00.260 and he was unable to call The Boston Home to let them 00:25:00.260 --> 00:25:01.570 know that this has happened. 00:25:01.570 --> 00:25:04.640 So they had to have someone who was passing by tell them 00:25:04.640 --> 00:25:06.830 that that happened. 00:25:06.830 --> 00:25:08.640 So this is the call light system. 00:25:08.640 --> 00:25:10.160 The button is pretty easy to press. 00:25:10.160 --> 00:25:12.400 It's just like a simple press. 00:25:12.400 --> 00:25:15.210 But, again, it's placed in this kind of inconvenient spot, 00:25:15.210 --> 00:25:16.346 where Margaret can't reach. 00:25:16.346 --> 00:25:17.720 She doesn't have much of a reach, 00:25:17.720 --> 00:25:22.410 so she can't reach up to press the button if need be. 00:25:22.410 --> 00:25:24.710 And so in addition to that, there's some other issues. 00:25:24.710 --> 00:25:28.170 Only one nurse is allowed to answer the calls at any time. 00:25:28.170 --> 00:25:28.920 Her name's Angela. 00:25:28.920 --> 00:25:30.230 And so she sit at the front desk, 00:25:30.230 --> 00:25:31.490 and this takes a long time if there 00:25:31.490 --> 00:25:33.060 are multiple residents calling in 00:25:33.060 --> 00:25:35.270 or if she has gone from the desk and has to address 00:25:35.270 --> 00:25:37.660 another resident's issues. 00:25:37.660 --> 00:25:41.660 So an aide also has to come in to turn off the call system, 00:25:41.660 --> 00:25:43.750 otherwise it keeps on beeping, and that 00:25:43.750 --> 00:25:46.617 is quite annoying for both the resident and the nurse. 00:25:46.617 --> 00:25:48.700 Many times, if there are two rooms within a suite, 00:25:48.700 --> 00:25:50.950 as it is with Margaret, so enter a door 00:25:50.950 --> 00:25:53.520 and there are two rooms there, sometimes the wrong room 00:25:53.520 --> 00:25:57.390 is answered, so you'll have the nurse call into the other room. 00:25:57.390 --> 00:25:59.850 And since this is a speaker system, 00:25:59.850 --> 00:26:02.600 if the resident is unable to speak really loudly, 00:26:02.600 --> 00:26:06.640 or, in Margaret's case, she once pulling out a chest of drawers 00:26:06.640 --> 00:26:07.830 and it fell on her. 00:26:07.830 --> 00:26:10.620 So she was unable to both reach the call light system. 00:26:10.620 --> 00:26:12.590 And if she had, she wouldn't have 00:26:12.590 --> 00:26:17.026 been able to speak loud enough for the nurse to hear her. 00:26:17.026 --> 00:26:18.650 And actually, to add to that, so that's 00:26:18.650 --> 00:26:20.233 the reason why we're planning on using 00:26:20.233 --> 00:26:21.790 an iPad for this solution. 00:26:21.790 --> 00:26:23.640 So we're planning on creating application, 00:26:23.640 --> 00:26:25.970 because Margaret always has her iPod with her, 00:26:25.970 --> 00:26:28.020 such that she can just press a couple of buttons 00:26:28.020 --> 00:26:29.895 and be able to talk with the nurses directly. 00:26:32.012 --> 00:26:34.470 LAURA D'AQUILA: So to talk more about assistive technology, 00:26:34.470 --> 00:26:36.810 both what Margaret herself uses and what 00:26:36.810 --> 00:26:39.171 other residents at The Boston Home use, 00:26:39.171 --> 00:26:40.920 Margaret, along with many other residents, 00:26:40.920 --> 00:26:43.860 uses a motorized wheelchair to get around. 00:26:43.860 --> 00:26:45.610 And Margaret is very tech savvy. 00:26:45.610 --> 00:26:48.130 She owns both an iPad and an iPhone, 00:26:48.130 --> 00:26:49.650 which she always has with her. 00:26:49.650 --> 00:26:52.520 And she owns a special stylus so that she's actually 00:26:52.520 --> 00:26:57.710 able to use her iPad and reach all ends of the screen. 00:26:57.710 --> 00:27:00.530 And they've come in handy in emergency situations. 00:27:00.530 --> 00:27:03.710 Tanya mentioned the time when the drawer fell on Margaret 00:27:03.710 --> 00:27:07.300 and she was unable to reach the existing call light system 00:27:07.300 --> 00:27:07.830 button. 00:27:07.830 --> 00:27:09.890 But fortunately, because she had her iPhone, 00:27:09.890 --> 00:27:13.060 she was able to call for help that way. 00:27:13.060 --> 00:27:16.040 And the Tanya had mentioned that Margaret is an artist, 00:27:16.040 --> 00:27:18.630 and she's able to use a mouthpiece 00:27:18.630 --> 00:27:21.540 to hold her paintbrush, and that's something 00:27:21.540 --> 00:27:23.520 that Don had designed for her. 00:27:23.520 --> 00:27:25.700 And along with other residents in the home, 00:27:25.700 --> 00:27:29.070 Margaret has the call light system button in her bedroom 00:27:29.070 --> 00:27:31.740 and also in the bathroom. 00:27:31.740 --> 00:27:36.020 So thanks to much of Don's work, The Boston Home is very open 00:27:36.020 --> 00:27:37.660 to assistive technology, and it's 00:27:37.660 --> 00:27:40.190 very prevalent within the home now. 00:27:40.190 --> 00:27:43.740 For example, there exists a cyber cafe, where resonance 00:27:43.740 --> 00:27:47.710 are able to use computers, and both the keyboards and mice 00:27:47.710 --> 00:27:51.000 within the cyber cafe are accessible to the needs 00:27:51.000 --> 00:27:56.000 of the residents with their limited arm mobility. 00:27:56.000 --> 00:27:59.150 And there are also speech therapists and occupational 00:27:59.150 --> 00:28:03.690 therapists on site, and these individuals use technology, 00:28:03.690 --> 00:28:06.560 such as iPads, in order to assess 00:28:06.560 --> 00:28:09.510 the progress of the residents. 00:28:09.510 --> 00:28:12.597 And Don has added many features to wheelchairs 00:28:12.597 --> 00:28:14.430 throughout his time their too, accommodating 00:28:14.430 --> 00:28:15.971 the different needs of the residents. 00:28:19.370 --> 00:28:22.460 TANYA TALKAR: So to assess how this application is going 00:28:22.460 --> 00:28:25.086 to work for Margaret and for the residents, because her vision 00:28:25.086 --> 00:28:26.460 is that at the end of this, we'll 00:28:26.460 --> 00:28:29.670 be able to have all 35 residents who are using iPads 00:28:29.670 --> 00:28:31.390 also use the system. 00:28:31.390 --> 00:28:32.990 We have a couple of success metrics. 00:28:32.990 --> 00:28:35.150 They're mostly qualitative. 00:28:35.150 --> 00:28:36.620 So, one, we just want to make sure 00:28:36.620 --> 00:28:38.703 that the correct iPad is being called and answered 00:28:38.703 --> 00:28:41.940 and that the correct resident is getting aid. 00:28:41.940 --> 00:28:44.490 We will also want to time the amount of time 00:28:44.490 --> 00:28:46.390 that it takes for a task to be completed. 00:28:46.390 --> 00:28:49.660 So suppose Margaret needs a refill of water, 00:28:49.660 --> 00:28:52.030 so the nurse will come in with the call light system, 00:28:52.030 --> 00:28:55.160 get the request, and then go back to get the water. 00:28:55.160 --> 00:28:59.430 versus if we have this on the iPad application, how much time 00:28:59.430 --> 00:29:00.320 that'll take. 00:29:00.320 --> 00:29:04.370 And then just success overall-- does this application actually 00:29:04.370 --> 00:29:06.670 integrate into the current system with the nurses? 00:29:06.670 --> 00:29:08.800 Will the nurses actually end up using the system? 00:29:08.800 --> 00:29:11.310 Will the residents actually end up using the system as well? 00:29:15.409 --> 00:29:16.950 LAURA D'AQUILA: So a few weeks ago we 00:29:16.950 --> 00:29:20.434 started discussing with Margaret potential solutions 00:29:20.434 --> 00:29:21.100 to this problem. 00:29:21.100 --> 00:29:23.660 Tanya had mentioned that we're going to be using an iPad. 00:29:23.660 --> 00:29:26.770 We work with Margaret to get her input and her feedback 00:29:26.770 --> 00:29:29.440 to actually develop some early sketches of what 00:29:29.440 --> 00:29:31.270 her end of this app looked like. 00:29:31.270 --> 00:29:33.390 And then within the next week, we 00:29:33.390 --> 00:29:36.320 developed this into a low fidelity iOS app, 00:29:36.320 --> 00:29:38.250 which I'll walk through now. 00:29:38.250 --> 00:29:40.630 So this is the home screen of the app 00:29:40.630 --> 00:29:42.970 that Margaret is going to have access to. 00:29:42.970 --> 00:29:45.060 It has two large by things that are 00:29:45.060 --> 00:29:48.930 color-coded red and black, for urgent and non-urgent requests. 00:29:48.930 --> 00:29:51.400 And should Margaret press Non-Urgent Request, 00:29:51.400 --> 00:29:56.040 she's taken to the next screen, which 00:29:56.040 --> 00:30:01.930 has six potentially customizable buttons for a common requests 00:30:01.930 --> 00:30:04.760 that Margaret may have for the nurse. 00:30:04.760 --> 00:30:06.960 For example, if she needs a cup of water 00:30:06.960 --> 00:30:09.330 or if she wants a nurse to come to a room, 00:30:09.330 --> 00:30:12.980 if she wants to be able to video conference with a nurse, 00:30:12.980 --> 00:30:14.700 these are all buttons that are easily 00:30:14.700 --> 00:30:16.550 accessible for her to press. 00:30:16.550 --> 00:30:20.580 And similarly, if Margaret presses the Urgent button, 00:30:20.580 --> 00:30:24.330 she's taken directly into a video call with a nurse. 00:30:24.330 --> 00:30:26.990 And at the bottom, there is a Cancel Call button for her 00:30:26.990 --> 00:30:30.279 to cancel in the event that she inadvertently 00:30:30.279 --> 00:30:31.070 pressed the button. 00:30:33.820 --> 00:30:36.130 TANYA TALKAR: So amazingly enough, 00:30:36.130 --> 00:30:39.090 right after we transferred this application to her iPad, 00:30:39.090 --> 00:30:40.810 she immediately went off to go talk 00:30:40.810 --> 00:30:43.268 to some of the other residents about the application, which 00:30:43.268 --> 00:30:44.150 is great. 00:30:44.150 --> 00:30:46.680 And so some of the feedback that she came up with 00:30:46.680 --> 00:30:48.980 was that she wanted to make sure that the buttons were 00:30:48.980 --> 00:30:52.380 large enough, in case residents end up having some fatigue 00:30:52.380 --> 00:30:54.710 and their fingers start dragging on the iPad. 00:30:54.710 --> 00:30:58.120 So she uses a stylus, but not all of the residents do. 00:30:58.120 --> 00:31:00.770 So we just make sure that we have larger buttons for this. 00:31:00.770 --> 00:31:02.940 She also wanted to make sure that there was 00:31:02.940 --> 00:31:04.660 an option to type in messages. 00:31:04.660 --> 00:31:07.940 So suppose any of the requests that a resident 00:31:07.940 --> 00:31:11.095 has isn't on the screen with six buttons, 00:31:11.095 --> 00:31:13.345 that they will be able to type in their own customized 00:31:13.345 --> 00:31:14.405 request. 00:31:14.405 --> 00:31:16.280 She also wants to make sure that she's always 00:31:16.280 --> 00:31:18.870 talking with the nurse through a video call 00:31:18.870 --> 00:31:21.700 because sometimes her message or what she wants 00:31:21.700 --> 00:31:24.020 isn't conveyed through text. 00:31:24.020 --> 00:31:26.940 And something that all of the residents said they wanted 00:31:26.940 --> 00:31:29.400 was that the application be voice-activated 00:31:29.400 --> 00:31:31.180 because not all of them are able to press 00:31:31.180 --> 00:31:34.270 the buttons at every time, and that they'll 00:31:34.270 --> 00:31:40.380 be able to go forward with this if they 00:31:40.380 --> 00:31:41.980 can't speak super well either. 00:31:46.089 --> 00:31:47.880 LAURA D'AQUILA: So in addition to Margaret, 00:31:47.880 --> 00:31:50.520 because of the nature of the system that we're building, 00:31:50.520 --> 00:31:52.420 we actually have an additional client, 00:31:52.420 --> 00:31:54.870 and that's the nurse on the other end of the system 00:31:54.870 --> 00:31:56.840 that Margaret's trying to reach. 00:31:56.840 --> 00:31:59.880 So we had mentioned all of these nice features 00:31:59.880 --> 00:32:02.720 that we want the app to have, for example, video chat. 00:32:02.720 --> 00:32:06.000 And none of this stuff is feasible with the existing 00:32:06.000 --> 00:32:09.200 call light system that exists already within the home. 00:32:09.200 --> 00:32:13.970 So because of that, we're hoping to bypass the existing 00:32:13.970 --> 00:32:17.630 system altogether and have the nurse on the other end 00:32:17.630 --> 00:32:20.290 have an iPad or a computer screen 00:32:20.290 --> 00:32:23.170 as well with an instance of this app running 00:32:23.170 --> 00:32:25.980 so that she can receive the requests from Margaret 00:32:25.980 --> 00:32:26.920 on this app. 00:32:26.920 --> 00:32:30.430 So because of this, we've had to speak with and work 00:32:30.430 --> 00:32:32.310 with Angela, who, as Tanya mentioned, 00:32:32.310 --> 00:32:35.990 is the nurse on the first floor, which is Margaret's floor, so 00:32:35.990 --> 00:32:38.870 that we can make sure that we can accommodate her needs. 00:32:38.870 --> 00:32:41.430 In addition to Margaret's needs in terms of what 00:32:41.430 --> 00:32:43.180 this application should have. 00:32:43.180 --> 00:32:45.970 And we've also worked with Don to make sure 00:32:45.970 --> 00:32:49.890 that this app is feasible to be adopted within the nurse's 00:32:49.890 --> 00:32:50.660 station. 00:32:50.660 --> 00:32:52.370 And within the next few weeks, we're 00:32:52.370 --> 00:32:57.390 also going to work on speaking with other management level 00:32:57.390 --> 00:32:59.270 people within The Boston Home to make sure 00:32:59.270 --> 00:33:03.080 that we're able to get their go-to as well. 00:33:03.080 --> 00:33:05.940 And one potential thing that we're still discussing 00:33:05.940 --> 00:33:12.260 is how to acquire a potential iPad that the nurse would 00:33:12.260 --> 00:33:13.094 need at her station. 00:33:13.094 --> 00:33:15.510 So we're looking into whether this is something The Boston 00:33:15.510 --> 00:33:17.450 Home would purchase, or whether it's something 00:33:17.450 --> 00:33:19.840 that we may need to get with our own team budget. 00:33:22.360 --> 00:33:25.710 So in terms of the timeline, we spent the first month speaking 00:33:25.710 --> 00:33:28.460 with Margaret, getting to know her, her needs, 00:33:28.460 --> 00:33:31.380 and what she's looking for in a potential solution. 00:33:31.380 --> 00:33:34.225 And then in October, we were able to assess 00:33:34.225 --> 00:33:35.980 in greater detail the feasibility 00:33:35.980 --> 00:33:39.270 of an iPad-based solution on both ends. 00:33:39.270 --> 00:33:40.970 We worked with Margaret and Angela. 00:33:40.970 --> 00:33:43.710 We developed a low fidelity prototypes for Margaret 00:33:43.710 --> 00:33:46.960 and tested this out and received feedback. 00:33:46.960 --> 00:33:49.710 And then in November, our plans include 00:33:49.710 --> 00:33:52.590 developing a low fidelity prototypes for Angela, 00:33:52.590 --> 00:33:55.619 for the nurses' side of the nurse call system. 00:33:55.619 --> 00:33:57.160 We hope to receive feedback from that 00:33:57.160 --> 00:33:59.510 and iterate through those prototypes as well. 00:33:59.510 --> 00:34:02.270 We also want to work on the back end of actually sending 00:34:02.270 --> 00:34:06.430 requests from Margaret's iPad to the nurses' iPads. 00:34:06.430 --> 00:34:09.810 And we want to get video conferencing set up 00:34:09.810 --> 00:34:11.090 the week after that. 00:34:11.090 --> 00:34:13.205 And then finally, hopefully by the end of November 00:34:13.205 --> 00:34:14.790 or beginning of December, we'll have 00:34:14.790 --> 00:34:17.310 an app that's able to be used within the home 00:34:17.310 --> 00:34:20.330 by not only Margaret, but potentially other residents 00:34:20.330 --> 00:34:23.489 in the home as well, and we can continue to test it out and get 00:34:23.489 --> 00:34:24.354 feedback from them. 00:34:27.855 --> 00:34:29.480 TANYA TALKAR: So a little bit about how 00:34:29.480 --> 00:34:32.360 the logistics for this project go-- our meetings are 00:34:32.360 --> 00:34:33.364 pretty conversational. 00:34:33.364 --> 00:34:35.030 They're less like an interview, and more 00:34:35.030 --> 00:34:38.760 just us talking with Margaret, Angela, Don. 00:34:38.760 --> 00:34:41.699 So Laura is mostly in charge of the videos and pictures, 00:34:41.699 --> 00:34:44.250 and then Beth and I are the ones who are taking notes, 00:34:44.250 --> 00:34:46.270 asking the questions. 00:34:46.270 --> 00:34:51.790 And we meet before the meetings to go over speaking notes 00:34:51.790 --> 00:34:53.810 and go over an agenda of what exactly 00:34:53.810 --> 00:34:57.130 we want to be accomplished during the meeting. 00:34:57.130 --> 00:35:00.370 As for division of work for the application itself, all of us 00:35:00.370 --> 00:35:02.410 are new to iOS development. 00:35:02.410 --> 00:35:04.120 So we're learning all of this together. 00:35:04.120 --> 00:35:06.244 We're planning on mostly working on the application 00:35:06.244 --> 00:35:08.650 as a team, all three of us together. 00:35:08.650 --> 00:35:10.840 And then for other things, Beth and Laura mainly 00:35:10.840 --> 00:35:14.069 worked on the video, and I was mostly in charge of the report 00:35:14.069 --> 00:35:16.110 and the presentation for the mid-semester panels. 00:35:21.019 --> 00:35:22.560 LAURA D'AQUILA: So to conclude, we're 00:35:22.560 --> 00:35:25.287 very excited to be working on this project with Margaret 00:35:25.287 --> 00:35:25.870 this semester. 00:35:25.870 --> 00:35:28.460 It's been a lot of fun so far, and it's exciting to us 00:35:28.460 --> 00:35:30.570 that this is something that could potentially not 00:35:30.570 --> 00:35:32.390 only benefit Margaret, but could also 00:35:32.390 --> 00:35:35.530 benefit many other residents of The Boston Home, 00:35:35.530 --> 00:35:37.640 should this be more universally adopted. 00:35:48.386 --> 00:35:49.760 PROFESSOR 2: So one of the things 00:35:49.760 --> 00:35:51.400 that you guys mentioned at the beginning, 00:35:51.400 --> 00:35:53.150 as you were talking about the call system, 00:35:53.150 --> 00:35:55.940 was some of the regulations that are in place at the home. 00:35:55.940 --> 00:35:59.270 Can you talk about how your system actually 00:35:59.270 --> 00:36:01.550 can map to some of those regulations, 00:36:01.550 --> 00:36:06.110 and if they have to change in any way to use your system? 00:36:08.294 --> 00:36:10.460 TANYA TALKAR: So that was actually one of the things 00:36:10.460 --> 00:36:13.043 that we are considering when we were thinking about whether we 00:36:13.043 --> 00:36:15.830 wanted to interface with the current call light system, 00:36:15.830 --> 00:36:18.539 or whether we would create this separate iPad application. 00:36:18.539 --> 00:36:20.080 And that's also one of things we need 00:36:20.080 --> 00:36:22.490 to talk with for administration. 00:36:22.490 --> 00:36:27.190 We believe that due to this being a separate application, 00:36:27.190 --> 00:36:30.450 we shouldn't need to have the nurses go in 00:36:30.450 --> 00:36:34.290 and turn off anything on the iPad, which 00:36:34.290 --> 00:36:38.140 is what they need to currently do with the call light system. 00:36:38.140 --> 00:36:40.570 And that's something that the company themselves 00:36:40.570 --> 00:36:42.490 had come up with as a regulation, that it 00:36:42.490 --> 00:36:44.700 would have to be turned off by a nurse aide. 00:36:44.700 --> 00:36:48.630 But for this, because it's the resident who's in charge of it, 00:36:48.630 --> 00:36:50.810 and they'll be video calling with the nurse, 00:36:50.810 --> 00:36:52.561 we believe that it shouldn't be a problem. 00:36:52.561 --> 00:36:54.560 PROFESSOR 2: So I guess my question is, how does 00:36:54.560 --> 00:36:55.880 that regulation actually map? 00:36:55.880 --> 00:36:58.710 So not the fact that the system requires it, 00:36:58.710 --> 00:37:00.720 but what is the kind of the purpose of having 00:37:00.720 --> 00:37:02.244 that regulation requirement, and is 00:37:02.244 --> 00:37:04.410 it something that you guys should be matching or not 00:37:04.410 --> 00:37:05.280 matching? 00:37:05.280 --> 00:37:07.210 It's an open question. 00:37:07.210 --> 00:37:10.260 Is there a benefit to having the nurse specifically 00:37:10.260 --> 00:37:12.750 go there and turn off, and did they 00:37:12.750 --> 00:37:15.122 design that into the system not because it 00:37:15.122 --> 00:37:16.830 was needed for the system, but because it 00:37:16.830 --> 00:37:20.010 was important for the task? 00:37:20.010 --> 00:37:22.774 TANYA TALKAR: So we've asked everyone about that. 00:37:22.774 --> 00:37:24.440 They haven't really been able to come up 00:37:24.440 --> 00:37:27.550 with an answer for that. 00:37:27.550 --> 00:37:30.410 Margaret herself kind of finds it intrusive 00:37:30.410 --> 00:37:33.090 that you have to come in and turn off the light manually, 00:37:33.090 --> 00:37:36.650 instead of her just being able to turn it off. 00:37:36.650 --> 00:37:39.310 So, yeah, we're not really completely sure 00:37:39.310 --> 00:37:42.194 why that is there. 00:37:42.194 --> 00:37:44.360 We just know that it's a regulation on the company's 00:37:44.360 --> 00:37:46.580 part. 00:37:46.580 --> 00:37:50.700 PROFESSOR 3: Well, it's clearly a Department of Public Health 00:37:50.700 --> 00:37:54.740 regulation, and it evolved out of abuse and neglect issues, 00:37:54.740 --> 00:38:00.210 where you could respond to a resident 00:38:00.210 --> 00:38:03.670 or just repeatedly shut their call request off, 00:38:03.670 --> 00:38:05.340 without really addressing a need. 00:38:05.340 --> 00:38:12.180 But skirting DPH-- sometimes you sort of 00:38:12.180 --> 00:38:15.170 have to play the game a little bit. 00:38:15.170 --> 00:38:20.430 So if it's an experimental or a redundant system, 00:38:20.430 --> 00:38:22.880 it may not have to match their regulations 00:38:22.880 --> 00:38:29.900 as long as the primary one meets those specific requirements 00:38:29.900 --> 00:38:36.730 of having someone go to attend to them. 00:38:36.730 --> 00:38:44.150 But I am curious how you honed in on that specific approach 00:38:44.150 --> 00:38:49.130 that you've taken of using the iPad and using that simple GUI, 00:38:49.130 --> 00:38:52.385 versus some of the ideas I had pitched initially. 00:38:54.607 --> 00:38:56.690 TANYA TALKAR: So I think I was mostly through just 00:38:56.690 --> 00:38:58.020 talking to Margaret. 00:38:58.020 --> 00:39:03.200 And her approach to this was that if she was in a situation 00:39:03.200 --> 00:39:05.780 where she wasn't able to reach the call light system, 00:39:05.780 --> 00:39:11.940 her immediate thought would be to use her iPhone 00:39:11.940 --> 00:39:13.740 and call The Boston Home and try and reach 00:39:13.740 --> 00:39:15.055 the nurses through that. 00:39:15.055 --> 00:39:18.960 And so we felt that that would be a little easier to interface 00:39:18.960 --> 00:39:21.630 in that way, in terms of she always has her iPad 00:39:21.630 --> 00:39:23.790 or her iPhone with her. 00:39:23.790 --> 00:39:27.890 And so suppose there were connectivity issues in terms 00:39:27.890 --> 00:39:31.667 of like we weren't unable to reach the-- suppose 00:39:31.667 --> 00:39:34.250 there was like a Bluetooth that was attached to the call light 00:39:34.250 --> 00:39:38.410 system, if that connectivity wasn't established and wasn't 00:39:38.410 --> 00:39:40.310 stable, then that would be an issue, 00:39:40.310 --> 00:39:42.730 as opposed to having Wi-Fi, which I think 00:39:42.730 --> 00:39:45.653 would be more reliable within the home and slightly 00:39:45.653 --> 00:39:46.819 outside of the home as well. 00:39:47.145 --> 00:39:47.895 PROFESSOR 3: Good. 00:39:53.550 --> 00:39:57.400 PROFESSOR 1: What I would ask is how much function does Margaret 00:39:57.400 --> 00:39:59.090 herself actually have? 00:39:59.090 --> 00:40:01.190 It's clear that you're trying to broaden 00:40:01.190 --> 00:40:03.700 this other members of The Boston Home, which is great, 00:40:03.700 --> 00:40:07.960 but what can Margaret herself do with an iPad app, 00:40:07.960 --> 00:40:11.550 and have you measured that, or have you observed 00:40:11.550 --> 00:40:14.920 her use of the prototype? 00:40:14.920 --> 00:40:19.230 LAURA D'AQUILA: So Margaret has limited use of her arms, 00:40:19.230 --> 00:40:22.160 and it varies depending on how tired she is. 00:40:22.160 --> 00:40:24.050 So when she's particularly fatigued, 00:40:24.050 --> 00:40:30.530 it's even harder for her to reach the full screen 00:40:30.530 --> 00:40:32.160 coverage of the iPad. 00:40:32.160 --> 00:40:35.180 But because of the fact that she has a stylus that definitely 00:40:35.180 --> 00:40:37.150 helps, but that's also part of the reason 00:40:37.150 --> 00:40:41.650 why we had looked into adding the large buttons 00:40:41.650 --> 00:40:45.980 so that it's more feasible for Margaret and other residents 00:40:45.980 --> 00:40:51.940 to be able to use all of these functionalities of the app. 00:40:51.940 --> 00:40:54.650 But, yeah, she can move her arms a little bit, but not very 00:40:54.650 --> 00:40:55.480 much. 00:40:55.480 --> 00:40:58.110 Tanya had mentioned that on the first day we met with her, 00:40:58.110 --> 00:41:04.900 we needed her to sign a contract for our team contract, 00:41:04.900 --> 00:41:07.380 and it was clearly a struggle for her 00:41:07.380 --> 00:41:10.590 to be able to move her arms to sign the document. 00:41:10.590 --> 00:41:13.920 When she paints, she uses a mouthpiece 00:41:13.920 --> 00:41:15.970 so that she can do it that way. 00:41:15.970 --> 00:41:25.080 So I'd say that her arm movement is pretty limited, 00:41:25.080 --> 00:41:29.040 but because of the stylus, she's able to at least get 00:41:29.040 --> 00:41:29.787 by with the iPad. 00:41:32.591 --> 00:41:34.757 PROFESSOR 2: We can probably take another one or two 00:41:34.757 --> 00:41:37.242 questions if anyone has comments. 00:41:43.206 --> 00:41:45.691 AUDIENCE: I have a question. 00:41:45.691 --> 00:41:48.673 You talked about there was that situation when someone fell 00:41:48.673 --> 00:41:50.164 over and was stuck in a ditch. 00:41:50.164 --> 00:41:55.850 How could they access this application in the iPad? 00:41:55.850 --> 00:41:57.215 Are you considering [INAUDIBLE]? 00:41:59.890 --> 00:42:01.630 LAURA D'AQUILA: Right, so maybe depending 00:42:01.630 --> 00:42:04.760 on the exact situation, they personally may not 00:42:04.760 --> 00:42:06.120 be able to use this app. 00:42:06.120 --> 00:42:08.130 But in the event that maybe there's 00:42:08.130 --> 00:42:09.935 another resident who's also outside, 00:42:09.935 --> 00:42:13.240 it may be a little bit easier for that second resident 00:42:13.240 --> 00:42:16.090 to call for help while they're still outside, as opposed 00:42:16.090 --> 00:42:18.200 to having to go into the building 00:42:18.200 --> 00:42:21.305 to alert the nurses of what had happened. 00:42:21.305 --> 00:42:22.680 But, yeah, in the event that it's 00:42:22.680 --> 00:42:28.860 just one person outside and depending on the situation, 00:42:28.860 --> 00:42:31.470 if they're not able to use the iPad, like if it fell 00:42:31.470 --> 00:42:34.005 or something, then I guess it wouldn't help them. 00:42:34.005 --> 00:42:35.380 But it's more so in the situation 00:42:35.380 --> 00:42:36.630 where there's multiple people. 00:42:39.386 --> 00:42:40.969 AUDIENCE: I thought it was interesting 00:42:40.969 --> 00:42:43.915 that you had identified the nurses as your second client. 00:42:43.915 --> 00:42:46.870 It's very smart of you to do that. 00:42:46.870 --> 00:42:51.699 How many signals are they being bombarded by on an average day, 00:42:51.699 --> 00:42:58.327 and how is that going to affect how you would get 00:42:58.327 --> 00:43:01.630 their attention [INAUDIBLE]? 00:43:01.630 --> 00:43:03.780 TANYA TALKAR: So Angela currently just 00:43:03.780 --> 00:43:07.500 has the nurse call system plus a computer set up at the desk. 00:43:07.500 --> 00:43:09.360 And then, of course, if there any nurses 00:43:09.360 --> 00:43:11.060 who are coming up to her to talk, 00:43:11.060 --> 00:43:12.900 that will be a distraction as well. 00:43:12.900 --> 00:43:14.910 So that was one of the primary things 00:43:14.910 --> 00:43:18.460 that we wanted to address with her when we talked to her. 00:43:18.460 --> 00:43:20.960 So that's why we're wondering, should it be on the computer, 00:43:20.960 --> 00:43:22.540 or should it be on a separate iPad? 00:43:22.540 --> 00:43:25.380 And she did tell us that with all the signals 00:43:25.380 --> 00:43:27.410 that she's getting, if it was on the computer, 00:43:27.410 --> 00:43:30.470 she would not be looking at it because you'll be most probably 00:43:30.470 --> 00:43:34.340 browsing other applications, if it's email or whatever. 00:43:34.340 --> 00:43:36.290 And then with the call light system, 00:43:36.290 --> 00:43:39.620 that is also something that beeps whenever someone calls 00:43:39.620 --> 00:43:40.840 in, so she will address that. 00:43:40.840 --> 00:43:42.600 But if there is an iPad just mounted 00:43:42.600 --> 00:43:44.480 like right in the middle there, she'll 00:43:44.480 --> 00:43:47.260 be able to see that as a notification coming in. 00:43:47.260 --> 00:43:50.490 And she said that because of where 00:43:50.490 --> 00:43:53.310 she is sitting at the desk, then she'll be able to see that. 00:43:59.706 --> 00:44:01.674 AUDIENCE: I just had a question. 00:44:01.674 --> 00:44:04.872 I noticed I didn't hear anything about what 00:44:04.872 --> 00:44:08.070 was the client [INAUDIBLE] nurse [INAUDIBLE] 00:44:08.070 --> 00:44:11.514 in terms of the [? hybrid ?] liability of this application. 00:44:11.514 --> 00:44:14.466 Have you guys considered putting that into your metric 00:44:14.466 --> 00:44:16.450 as well for success? 00:44:16.450 --> 00:44:19.240 Like what does she expect to work 00:44:19.240 --> 00:44:22.120 90% of the time, 80% of the time? 00:44:22.120 --> 00:44:26.100 And also, what [INAUDIBLE]? 00:44:26.100 --> 00:44:27.974 You know, complicated systems are complicated 00:44:27.974 --> 00:44:31.646 for a reason Maybe that's something-- like have you 00:44:31.646 --> 00:44:33.770 guys had a conversation with the client about this? 00:44:37.496 --> 00:44:39.370 LAURA D'AQUILA: We haven't had a conversation 00:44:39.370 --> 00:44:42.060 about a specific number, but one of the benefits 00:44:42.060 --> 00:44:45.820 to the fact that we have this iPad system on top 00:44:45.820 --> 00:44:49.680 of the existing system is that in the event that Wi-Fi goes 00:44:49.680 --> 00:44:51.390 out or something like that in the home, 00:44:51.390 --> 00:44:54.730 and the iPad app that isn't working, 00:44:54.730 --> 00:44:57.090 then Margaret does have the ability 00:44:57.090 --> 00:45:01.540 to simply use the system that's in place, which I think 00:45:01.540 --> 00:45:05.970 is known to at least go through to the nurse pretty reliably, 00:45:05.970 --> 00:45:08.740 if not receive a response all the time. 00:45:08.740 --> 00:45:11.240 PROFESSOR 2: All right, let's have Team [? Aaron ?] come up. 00:45:20.070 --> 00:45:21.840 PHILIP: So hello, everyone. 00:45:21.840 --> 00:45:23.400 We're Team Kate. 00:45:23.400 --> 00:45:24.979 My name is Philip [INAUDIBLE]. 00:45:24.979 --> 00:45:26.104 And my teammates here are-- 00:45:26.104 --> 00:45:28.096 JENNY: Jenny. 00:45:28.096 --> 00:45:30.090 RAQUEL: Hi, I'm Raquel. 00:45:30.090 --> 00:45:32.751 [? PHILIP: So ?] today we're just going to talk about 00:45:32.751 --> 00:45:35.250 the progress that we've made over the course of the last few 00:45:35.250 --> 00:45:37.760 weeks in our project with Kate. 00:45:37.760 --> 00:45:41.090 Let me quickly introduce who our client is. 00:45:41.090 --> 00:45:44.070 Over the last few weeks, we've been talking about Kate. 00:45:44.070 --> 00:45:47.130 She's our client, and she works at the Cambridge Disabilities 00:45:47.130 --> 00:45:48.400 Commission. 00:45:48.400 --> 00:45:52.680 She has profound hearing loss, and wears a cochlear implant. 00:45:52.680 --> 00:45:55.740 We also have this really short video, about two minutes long, 00:45:55.740 --> 00:45:58.250 in which talks about herself and a little bit more 00:45:58.250 --> 00:46:00.340 about the hearing impairment that she has. 00:46:00.340 --> 00:46:03.322 [VIDEO PLAYBACK] 00:46:08.800 --> 00:46:11.790 -Without my cochlear implants, I have no residual hearing 00:46:11.790 --> 00:46:15.940 at all, so that would be considered profound. 00:46:15.940 --> 00:46:21.106 With my cochlear implants, I have a mild to moderate hearing 00:46:21.106 --> 00:46:21.605 loss. 00:46:21.605 --> 00:46:24.360 But obviously, I do really well with my implants. 00:46:24.360 --> 00:46:25.940 You through in any background noise, 00:46:25.940 --> 00:46:27.870 and it's just you can forget about it. 00:46:27.870 --> 00:46:29.360 In this kind of setting I do really 00:46:29.360 --> 00:46:30.651 well with my cochlear implants. 00:46:35.970 --> 00:46:38.875 So I was born with a very mild hearing loss. 00:46:38.875 --> 00:46:41.360 I just had like preferential seating in school. 00:46:41.360 --> 00:46:44.110 And it became profound or rapidly progressive 00:46:44.110 --> 00:46:46.080 when I was 13. 00:46:46.080 --> 00:46:50.230 It went from mild to moderate to severe and then to profound. 00:46:50.230 --> 00:46:54.210 I got my first cochlear implant my left side in 1999. 00:46:54.210 --> 00:47:03.230 I had my right side done in 2008, so nine years later. 00:47:03.230 --> 00:47:06.020 It is not a quick fix. 00:47:06.020 --> 00:47:08.314 So when it was first turned on, everything, 00:47:08.314 --> 00:47:10.230 like my brother's would like stomp their feet, 00:47:10.230 --> 00:47:12.604 and it would sound like someone was ringing little bells. 00:47:12.604 --> 00:47:13.370 It was weird. 00:47:13.370 --> 00:47:15.790 And I couldn't understand any speech, 00:47:15.790 --> 00:47:18.780 but I had to force myself to turn my hearing aid off 00:47:18.780 --> 00:47:19.960 on the right side. 00:47:19.960 --> 00:47:25.200 And I was home from college for six or seven weeks. 00:47:25.200 --> 00:47:28.970 and I did all these listening exercises with my family. 00:47:28.970 --> 00:47:30.150 We made it a game. 00:47:30.150 --> 00:47:32.220 Like my mom would take children's books. 00:47:32.220 --> 00:47:34.950 And at first, she would read them aloud, 00:47:34.950 --> 00:47:36.970 and I would follow along, trying to place what 00:47:36.970 --> 00:47:38.421 I was hearing with the words. 00:47:38.421 --> 00:47:39.920 And then I would graduate from that, 00:47:39.920 --> 00:47:43.009 and I wasn't allowed to follow along-- to read along. 00:47:43.009 --> 00:47:44.550 and I was trying to follow the story, 00:47:44.550 --> 00:47:47.060 just basically training my brain. 00:47:47.060 --> 00:47:51.560 So my brain was receiving the signal in a slightly new way. 00:47:51.560 --> 00:47:53.580 And so I basically had to retrain my brain 00:47:53.580 --> 00:47:56.420 how to take that signal and interpret it into usable sound. 00:48:00.560 --> 00:48:02.630 I mean, I can't tell you how much 00:48:02.630 --> 00:48:03.990 it has changed my life though. 00:48:03.990 --> 00:48:05.800 Like I used to walk around college 00:48:05.800 --> 00:48:09.130 with a little whiteboard, and people would write notes to me. 00:48:09.130 --> 00:48:13.670 It has completely changed my life-- completely. 00:48:13.670 --> 00:48:14.650 So for me. 00:48:14.650 --> 00:48:16.880 It was so worth it. 00:48:20.608 --> 00:48:24.427 [END PLAYBACK] 00:48:24.427 --> 00:48:26.260 PHILIP: So we've already seen from the video 00:48:26.260 --> 00:48:27.990 that Katie uses cochlear implants, 00:48:27.990 --> 00:48:31.490 and on this I would just like to mention 00:48:31.490 --> 00:48:34.420 that a lot of people who have hearing impediments 00:48:34.420 --> 00:48:39.650 still have functional nerve ending, the auditory nerves. 00:48:39.650 --> 00:48:42.104 The main problem is just that the part 00:48:42.104 --> 00:48:44.860 of the ear that is responsible for transmitting 00:48:44.860 --> 00:48:49.160 sound to an electric signals that are translated 00:48:49.160 --> 00:48:52.000 by the brain aren't functional. 00:48:52.000 --> 00:48:55.700 So it is that part of the ear that the cochlear implant 00:48:55.700 --> 00:48:57.905 tries to fix. 00:48:57.905 --> 00:48:59.280 So the cochlear implant basically 00:48:59.280 --> 00:49:01.390 provides a new channel through which sound 00:49:01.390 --> 00:49:05.400 signals can be transmitted to electrical signals 00:49:05.400 --> 00:49:07.840 for the brain to interpret. 00:49:07.840 --> 00:49:10.300 RAQUEL: So now we can get into a little bit of what 00:49:10.300 --> 00:49:13.200 our goals is a Team Kate. 00:49:13.200 --> 00:49:16.370 So our major goal here is to create cochlear implant 00:49:16.370 --> 00:49:19.990 attachments, so whether it's covers or clip-on add-ons 00:49:19.990 --> 00:49:23.740 to her cochlear implant to kind of hit on three 00:49:23.740 --> 00:49:26.950 particular sub-goals in this. 00:49:26.950 --> 00:49:29.580 So the first is to provide some water resistance 00:49:29.580 --> 00:49:30.210 to her implant. 00:49:30.210 --> 00:49:32.210 So currently, it isn't water resistant, 00:49:32.210 --> 00:49:35.940 and she doesn't have a cover that she uses for that. 00:49:35.940 --> 00:49:39.260 So to give some context for that desire 00:49:39.260 --> 00:49:41.990 is that she, just like any of us, 00:49:41.990 --> 00:49:44.930 often finds ourselves in the rain. 00:49:44.930 --> 00:49:46.970 It seems like it's a great day to begin with, 00:49:46.970 --> 00:49:49.290 and by the end of day, it's pouring. 00:49:49.290 --> 00:49:51.890 So for Kate that means walking around with her hands 00:49:51.890 --> 00:49:53.650 like this, covering her implants, 00:49:53.650 --> 00:49:55.900 or taking off her implants entirely, 00:49:55.900 --> 00:50:00.810 and that's not ideal because she can no longer hear. 00:50:00.810 --> 00:50:03.300 A second goal for our implant covers 00:50:03.300 --> 00:50:06.850 are to provide some sort of sound blocking. 00:50:06.850 --> 00:50:11.820 So Kate has issues in noisy environments. 00:50:11.820 --> 00:50:15.192 And what I mean by this is like in a lobby or a restaurant 00:50:15.192 --> 00:50:17.400 where there's just lots of background noise going on, 00:50:17.400 --> 00:50:19.260 she has problems distinguishing sounds 00:50:19.260 --> 00:50:21.804 that are coming from behind her from sounds that are 00:50:21.804 --> 00:50:22.970 coming from in front of her. 00:50:22.970 --> 00:50:25.019 So she's having a conversation with somebody. 00:50:25.019 --> 00:50:26.560 It's hard to actually comprehend what 00:50:26.560 --> 00:50:29.450 they're saying when there's lots of noise from behind. 00:50:29.450 --> 00:50:32.460 And currently, her implant just has a single microphone 00:50:32.460 --> 00:50:34.840 so there's no kind of sound directionality 00:50:34.840 --> 00:50:36.380 capability to it. 00:50:36.380 --> 00:50:38.850 And so an idea for this is just provide 00:50:38.850 --> 00:50:41.360 some sort of physical barrier to basically block sound 00:50:41.360 --> 00:50:43.820 from behind her. 00:50:43.820 --> 00:50:45.440 The third thing here is attachedness. 00:50:45.440 --> 00:50:48.770 So she has a problem with her cochlear implants 00:50:48.770 --> 00:50:52.280 just falling off all the time for different reasons. 00:50:52.280 --> 00:50:55.766 But one goal for us is to try to just provide 00:50:55.766 --> 00:50:57.890 something that gives it a little bit more stability 00:50:57.890 --> 00:51:00.650 so it just stays on her head more. 00:51:00.650 --> 00:51:02.820 So the context of that one in particular 00:51:02.820 --> 00:51:05.520 is really just any place, any time. 00:51:05.520 --> 00:51:07.390 The context for all of these are kind 00:51:07.390 --> 00:51:09.790 of just very portable things that she 00:51:09.790 --> 00:51:11.410 can use in her everyday life. 00:51:15.590 --> 00:51:17.730 So we've come up with a few success metrics. 00:51:17.730 --> 00:51:21.680 We haven't formally tested these yet. 00:51:21.680 --> 00:51:23.280 But for the water resistance goal 00:51:23.280 --> 00:51:25.600 here, we'll be doing something like a water bead test 00:51:25.600 --> 00:51:28.660 for the material to make sure that it's water resistant. 00:51:31.540 --> 00:51:33.650 I guess I should say that Kate has gotten 00:51:33.650 --> 00:51:37.150 a demo of her cochlear implant from the company that 00:51:37.150 --> 00:51:40.290 makes her implants, so we can do these water resistance tests 00:51:40.290 --> 00:51:42.120 not on her actual implant. 00:51:42.120 --> 00:51:45.090 But something like putting a material, like a paper towel 00:51:45.090 --> 00:51:47.650 or something that would show wetness, around the implant, 00:51:47.650 --> 00:51:49.760 putting on her cover, spraying it, and looking 00:51:49.760 --> 00:51:52.990 for signs of wetness and where that wetness is coming in. 00:51:52.990 --> 00:51:54.710 Sound blocking, what we plan to do 00:51:54.710 --> 00:51:58.070 is kind of a human subject experiment with her. 00:51:58.070 --> 00:52:01.910 So what we'll do is play noise, a noisy environment behind her 00:52:01.910 --> 00:52:04.440 from different audio clips. 00:52:04.440 --> 00:52:06.450 and then have audio clips in front of her 00:52:06.450 --> 00:52:09.000 of speech or just a conversation, 00:52:09.000 --> 00:52:11.290 and try to kind of get her subjective feedback, 00:52:11.290 --> 00:52:15.280 and identify her threshold for the volume of that conversation 00:52:15.280 --> 00:52:17.370 in front of her, and when she recognize that 00:52:17.370 --> 00:52:20.609 with and without our different sound-blocking devices. 00:52:20.609 --> 00:52:22.400 And then attachedness-- so currently, we've 00:52:22.400 --> 00:52:25.510 talked to Kate, and her cochlear implants can fall out 00:52:25.510 --> 00:52:29.230 up to 10 or 12 times a day, and this isn't even necessarily 00:52:29.230 --> 00:52:31.220 when she's being particularly active. 00:52:31.220 --> 00:52:33.930 So our goal is something less than three time a day, 00:52:33.930 --> 00:52:36.096 just something more reasonable for her to deal with. 00:52:43.690 --> 00:52:46.310 JENNY: So during our design process, we talked to Kate, 00:52:46.310 --> 00:52:49.030 and he's really, really excited about this project 00:52:49.030 --> 00:52:52.380 because it has been a problem for her for a very long time, 00:52:52.380 --> 00:52:56.040 and she showed us a bunch of her existing solutions she has. 00:52:56.040 --> 00:52:59.190 She had a head band that you could hook the implants into, 00:52:59.190 --> 00:53:00.890 and that would keep them in place. 00:53:00.890 --> 00:53:02.840 But it's very sporty. 00:53:02.840 --> 00:53:06.057 It's a bright colored headband, and it wasn't something 00:53:06.057 --> 00:53:07.140 that she was pleased with. 00:53:07.140 --> 00:53:12.280 And then she also had some other kind of neoprene sleeves 00:53:12.280 --> 00:53:15.850 that she could put over her implants, 00:53:15.850 --> 00:53:20.920 but these technologies were all like pretty primitive, 00:53:20.920 --> 00:53:27.500 and they only served to solve one problem at once. 00:53:27.500 --> 00:53:32.970 So through talking to her, we identified a bunch of feature 00:53:32.970 --> 00:53:34.810 that we wanted to address, the three 00:53:34.810 --> 00:53:37.260 features-- the water resistance, sound blocking, 00:53:37.260 --> 00:53:40.400 and attachedness-- and we began prototyping. 00:53:40.400 --> 00:53:44.270 So we each individually sketched designs 00:53:44.270 --> 00:53:47.126 so we could come up with many ideas when we came together. 00:53:47.126 --> 00:53:52.200 And as a team we chose the few to prototype out. 00:53:52.200 --> 00:53:54.410 And I'll show that on the next slide. 00:53:54.410 --> 00:53:59.730 But we used [INAUDIBLE], which were two materials that we 00:53:59.730 --> 00:54:01.590 discovered during lecture. 00:54:01.590 --> 00:54:05.310 And then last week we presented the prototypes to Kate 00:54:05.310 --> 00:54:08.410 and did some informal testing. 00:54:08.410 --> 00:54:10.380 And she was pretty impressed them, 00:54:10.380 --> 00:54:16.220 and that leads me to the next slide of what we made so far. 00:54:16.220 --> 00:54:19.190 So at the beginning, we wanted to create 00:54:19.190 --> 00:54:22.310 some sort of all-on-one attachment 00:54:22.310 --> 00:54:25.340 that would address all three of the problems. 00:54:25.340 --> 00:54:33.090 So on the left, you can see it's like a unibody cover that 00:54:33.090 --> 00:54:34.900 covers the entire implant that also 00:54:34.900 --> 00:54:39.250 provides a hood over the microphone at the very top. 00:54:39.250 --> 00:54:41.950 And then there's also a little ear bud 00:54:41.950 --> 00:54:44.730 that would help with the attachments. 00:54:44.730 --> 00:54:48.670 We decide not to go with that because Kate wanted something 00:54:48.670 --> 00:54:51.530 a little more modular, something that she could just 00:54:51.530 --> 00:54:56.560 have separate accessories for each problem. 00:54:56.560 --> 00:55:03.270 So when we prototyped keeping this in mind, 00:55:03.270 --> 00:55:05.700 we created separate covers. 00:55:05.700 --> 00:55:08.990 So the left of the top right photo 00:55:08.990 --> 00:55:12.040 are covers for the coil and the implant 00:55:12.040 --> 00:55:15.050 itself, the device with processor. 00:55:15.050 --> 00:55:19.130 And then we also created some sort of hood 00:55:19.130 --> 00:55:22.510 that you can put right over the microphone, which 00:55:22.510 --> 00:55:25.402 it's a little hard to tell, but the microphone right here. 00:55:25.402 --> 00:55:27.110 So this hood, it provides a small barrier 00:55:27.110 --> 00:55:34.240 from the sound traveling from behind to hit the microphone. 00:55:34.240 --> 00:55:42.875 So we tried this out and then also compared 00:55:42.875 --> 00:55:49.040 it to these previously existing devices. 00:55:49.040 --> 00:55:54.470 They're called Ear Glasses, and these help also 00:55:54.470 --> 00:55:58.710 amplify sound that's coming toward you. 00:55:58.710 --> 00:56:01.940 And she was pretty pleased with them. 00:56:01.940 --> 00:56:04.630 And this was like very informal, so we 00:56:04.630 --> 00:56:08.890 plan to continue to prototype and iterate our design 00:56:08.890 --> 00:56:11.640 and then bring something to show her on Thursday. 00:56:16.562 --> 00:56:18.020 For the rest of the semester, we're 00:56:18.020 --> 00:56:23.760 looking to continue measuring and testing out our success 00:56:23.760 --> 00:56:27.090 metrics with the prototypes that we're planning to build. 00:56:27.090 --> 00:56:28.940 And then in November, we hope to finalize 00:56:28.940 --> 00:56:30.565 the design and the materials that we're 00:56:30.565 --> 00:56:35.390 going to use and then create our final deliverable. 00:56:35.390 --> 00:56:37.660 We're looking, like materials wise, 00:56:37.660 --> 00:56:40.010 we're keeping 3D printing in mind 00:56:40.010 --> 00:56:43.180 to actually create the attachments. 00:56:43.180 --> 00:56:47.583 But we haven't finalized it yet, so that's just something 00:56:47.583 --> 00:56:48.764 that we're looking at ahead. 00:56:48.764 --> 00:56:51.425 And that concludes our presentation. 00:56:51.425 --> 00:56:53.091 Thank you, and we'll take any questions. 00:57:04.540 --> 00:57:07.090 PROFESSOR 1: First, that was a really nice video explaining 00:57:07.090 --> 00:57:10.590 her story with getting the cochlear implants 00:57:10.590 --> 00:57:13.320 and what kind of change they've made in her life. 00:57:13.320 --> 00:57:17.070 I'm curious about a couple of other aspects of your client 00:57:17.070 --> 00:57:19.795 that you alluded to a little bit, 00:57:19.795 --> 00:57:21.870 but I was wondering how important they are. 00:57:21.870 --> 00:57:26.940 First, how active or athletic is she, and is it important to her 00:57:26.940 --> 00:57:30.820 that these things be really, really secure? 00:57:30.820 --> 00:57:33.636 And second, how sensitive is she to her appearance? 00:57:37.450 --> 00:57:40.232 RAQUEL: So she's not particularly active. 00:57:40.232 --> 00:57:41.690 What she did tell us is that she'll 00:57:41.690 --> 00:57:44.610 starting pool therapy soon for another condition 00:57:44.610 --> 00:57:47.650 that she has that we didn't talk about here, 00:57:47.650 --> 00:57:50.420 but that she'll be using the headband because it's 00:57:50.420 --> 00:57:52.530 really important that they don't fall off at all. 00:57:52.530 --> 00:57:55.060 And she'll be in shallow end and there will basically 00:57:55.060 --> 00:57:56.490 be no water touching them. 00:57:56.490 --> 00:57:59.050 But so for these it's really just kind of daily life. 00:57:59.050 --> 00:58:00.380 She works in an office. 00:58:00.380 --> 00:58:02.940 She attends a lot of meetings. 00:58:02.940 --> 00:58:03.960 So nothing too active. 00:58:03.960 --> 00:58:06.010 She does ride her bike every once in awhile, 00:58:06.010 --> 00:58:07.968 and she has issues when she puts on her helmet. 00:58:07.968 --> 00:58:09.720 But again, she uses that headband 00:58:09.720 --> 00:58:14.330 that just really keeps it secure on her head for those purposes. 00:58:14.330 --> 00:58:18.020 And about her caring about what she looks like, we actually 00:58:18.020 --> 00:58:20.442 did ask her straight up, how do you feel 00:58:20.442 --> 00:58:21.650 about looking a little silly? 00:58:21.650 --> 00:58:22.790 Is that OK? 00:58:22.790 --> 00:58:26.820 And she said that's fine. 00:58:26.820 --> 00:58:28.020 I think there's a fine line. 00:58:28.020 --> 00:58:32.430 We don't want something that's crazy sticking out. 00:58:32.430 --> 00:58:35.560 But I think she's willing to have a little bit of something 00:58:35.560 --> 00:58:36.330 extra on her head. 00:58:36.330 --> 00:58:38.640 She's even told us that she prefers it 00:58:38.640 --> 00:58:41.260 when people can see that she has a cochlear implant, instead 00:58:41.260 --> 00:58:45.860 of covering it up so that they automatically know that she has 00:58:45.860 --> 00:58:48.806 hearing loss so that they can communicate better with her 00:58:48.806 --> 00:58:50.472 from the beginning of talking with them. 00:58:53.294 --> 00:58:55.460 PROFESSOR 2: So I'm wondering if you could talk more 00:58:55.460 --> 00:58:57.710 about that design shape. 00:58:57.710 --> 00:59:00.470 So you had the kind of Ear Glasses 00:59:00.470 --> 00:59:03.440 as something that was clearly doing something similar that 00:59:03.440 --> 00:59:05.810 provides that directionality. 00:59:05.810 --> 00:59:08.920 And in your design, you showed kind of two different methods 00:59:08.920 --> 00:59:12.180 of a different shape that was on that hood for how 00:59:12.180 --> 00:59:13.767 you're doing that. 00:59:13.767 --> 00:59:15.850 I'm wondering-- I know you said you guys are still 00:59:15.850 --> 00:59:18.520 kind of the middle of testing and testing out of it. 00:59:18.520 --> 00:59:24.940 How is that shape playing into your kind of design decisions? 00:59:24.940 --> 00:59:27.580 Are you are you specifically designing shapes and testing 00:59:27.580 --> 00:59:29.440 them, or is that more aesthetic? 00:59:32.967 --> 00:59:34.550 JENNY: To be honest, we haven't tested 00:59:34.550 --> 00:59:36.810 that many shapes out yet. 00:59:36.810 --> 00:59:39.250 I think that when we do create a lot shapes, 00:59:39.250 --> 00:59:41.760 we're going to look at effectiveness 00:59:41.760 --> 00:59:43.092 before aesthetics. 00:59:46.700 --> 00:59:49.880 And we tried out different sizes so far, 00:59:49.880 --> 00:59:52.314 or we tried out three different sizes 00:59:52.314 --> 00:59:58.788 so far of the sound blocking piece, 00:59:58.788 --> 01:00:01.776 and definitely the largest one actually 01:00:01.776 --> 01:00:03.270 works the most effectively. 01:00:03.270 --> 01:00:07.752 So we're going to find a balance between portability 01:00:07.752 --> 01:00:10.242 and effectiveness. 01:00:13.667 --> 01:00:15.750 PROFESSOR 3: Any questions from the audience here? 01:00:15.750 --> 01:00:17.291 If we can have the last team as well. 01:00:17.291 --> 01:00:21.314 Jeffrey, [INAUDIBLE] and get set up as well. 01:00:21.314 --> 01:00:23.456 Any other questions or comments? 01:00:23.456 --> 01:00:25.706 AUDIENCE: How are the ear glasses supposed to stay on? 01:00:30.952 --> 01:00:32.618 JENNY: As advertised, they were supposed 01:00:32.618 --> 01:00:34.076 to have some sort of adhesive strip 01:00:34.076 --> 01:00:36.794 that you can just pull off and then stick on. 01:00:36.794 --> 01:00:40.314 But they don't actually do that. 01:00:40.314 --> 01:00:41.730 It didn't actually come with that, 01:00:41.730 --> 01:00:43.650 so they just sit on your ear. 01:00:43.650 --> 01:00:45.570 But when we had her try them on, we just 01:00:45.570 --> 01:00:47.970 wanted her to try it on for the shape of the ear glasses. 01:00:47.970 --> 01:00:51.378 And she was really impressed by how big of a difference 01:00:51.378 --> 01:00:52.866 it made with her microphone. 01:00:52.866 --> 01:00:54.241 RAQUEL: But these, in particular, 01:00:54.241 --> 01:00:56.834 won't stay on very well for us, and they definitely 01:00:56.834 --> 01:00:58.500 don't stay on with her cochlear implant. 01:01:01.190 --> 01:01:03.760 PROFESSOR 3: I assume that magnets would 01:01:03.760 --> 01:01:05.860 be a problem with the implants. 01:01:05.860 --> 01:01:08.090 I don't know if you address that specifically. 01:01:08.090 --> 01:01:13.960 I'm just thinking of how well devices click in place. 01:01:13.960 --> 01:01:16.913 I'm just thinking quick one in the extruder head 01:01:16.913 --> 01:01:20.070 on the 3D printer, how would you just get sort of lined up, 01:01:20.070 --> 01:01:21.630 and it jumps into place. 01:01:21.630 --> 01:01:24.680 And I like that functionality, but I'm 01:01:24.680 --> 01:01:26.480 wondering-- I'm assuming-- that that would 01:01:26.480 --> 01:01:27.688 be problem with the implants. 01:01:30.742 --> 01:01:33.200 PHILIP: It's actually one of the things that we considered. 01:01:33.200 --> 01:01:35.410 But just like you said, we weren't 01:01:35.410 --> 01:01:37.460 sure about how adding a magnet to the system 01:01:37.460 --> 01:01:40.635 would affect the way the outer part 01:01:40.635 --> 01:01:44.872 of the implanted part of it. 01:01:44.872 --> 01:01:46.580 So we haven't really tried that yet here. 01:01:46.580 --> 01:01:49.270 But I think we're going to explore that option 01:01:49.270 --> 01:01:54.520 a little bit more and see how it affects the communication. 01:01:54.520 --> 01:01:56.270 If it doesn't have that much of an impact, 01:01:56.270 --> 01:01:58.560 then we would use it. 01:02:00.189 --> 01:02:02.480 PROFESSOR 3: Any final questions or anything like that? 01:02:06.890 --> 01:02:09.340 AUDIENCE: One quick thing is you may [INAUDIBLE] 01:02:09.340 --> 01:02:13.126 think about the shape, the engineering of it. 01:02:13.126 --> 01:02:15.292 There's some principles to apply to kind of engineer 01:02:15.292 --> 01:02:21.002 a shape that is most effective for sound filtering 01:02:21.002 --> 01:02:21.792 or sound blocking. 01:02:21.792 --> 01:02:22.740 That kind of thing. 01:02:22.740 --> 01:02:24.180 OK, Thank you. 01:02:30.360 --> 01:02:31.790 Hi, so we're Team Jeffery. 01:02:33.164 --> 01:02:34.080 JODIE CHEN: I'm Jodie. 01:02:34.303 --> 01:02:35.136 DAVID KE: I'm David. 01:02:37.220 --> 01:02:39.045 JODIE CHEN: And our client is Jeffrey. 01:02:39.045 --> 01:02:42.910 Here's a picture of him, and he's blind. 01:02:42.910 --> 01:02:45.290 So first, we're going to talk about contextual inquiry 01:02:45.290 --> 01:02:47.670 and how we worked with the HAAT model. 01:02:47.670 --> 01:02:49.790 So we came up with a few questions 01:02:49.790 --> 01:02:51.770 that we planned on asking him to kind of get 01:02:51.770 --> 01:02:53.909 an idea of what activities he enjoys doing 01:02:53.909 --> 01:02:55.700 and which activities we can help streamline 01:02:55.700 --> 01:03:00.125 or make more efficient and allow him to, I guess, enjoy it more. 01:03:00.125 --> 01:03:01.500 So we kind of asked him questions 01:03:01.500 --> 01:03:02.874 like, what activities do you want 01:03:02.874 --> 01:03:04.300 to be able to do independently? 01:03:04.300 --> 01:03:07.290 And we asked him to show as an activity 01:03:07.290 --> 01:03:09.620 that he enjoyed in his free time and also like 01:03:09.620 --> 01:03:11.550 how he uses computers, because it turns out 01:03:11.550 --> 01:03:13.930 that he uses computers a lot. 01:03:13.930 --> 01:03:16.550 So I think one thing that we found 01:03:16.550 --> 01:03:20.360 about Jeffrey is that he's actually extremely independent, 01:03:20.360 --> 01:03:21.860 even though he's blind. 01:03:21.860 --> 01:03:24.070 He told us that like 75% of blind people 01:03:24.070 --> 01:03:27.275 are like unemployed, but he's been employed 01:03:27.275 --> 01:03:29.530 in multiple places before, and he also continues 01:03:29.530 --> 01:03:30.920 to do a lot of financial work. 01:03:30.920 --> 01:03:34.740 So we have a video to kind of show, I guess, 01:03:34.740 --> 01:03:38.735 how he's l challenged our misconceptions. 01:03:38.735 --> 01:03:43.082 [VIDEO PLAYBACK] 01:03:44.060 --> 01:03:46.360 -Hi, so I'm David, and I'm part of Team Jeffrey 01:03:46.360 --> 01:03:48.350 with Jodie Chen and Yi Tong. 01:03:48.350 --> 01:03:50.726 And the client that we're working with for PPAT, his name 01:03:50.726 --> 01:03:53.050 is Jeffrey, and he's blind. 01:03:53.050 --> 01:03:55.379 I guess initially going into this project, 01:03:55.379 --> 01:03:57.920 I didn't really know what I was expecting in terms of working 01:03:57.920 --> 01:04:00.340 with a person with blindness. 01:04:00.340 --> 01:04:02.560 I guess, part of it's like I didn't expect them 01:04:02.560 --> 01:04:04.300 to be super self-sufficient. 01:04:04.300 --> 01:04:06.000 And I thought they would have to be 01:04:06.000 --> 01:04:09.042 relying on a lot of technologies to go through their day. 01:04:09.042 --> 01:04:11.500 [? And so I was like ?] struggle with like a decent portion 01:04:11.500 --> 01:04:14.255 of the daily activities. 01:04:14.255 --> 01:04:16.630 -I guess something that really surprised me about Jeffrey 01:04:16.630 --> 01:04:21.016 was how autonomous he is in like his travel and other stuff. 01:04:21.016 --> 01:04:22.976 So what you might not know about Jeffrey 01:04:22.976 --> 01:04:26.752 is that during our Monday and Wednesday classes sessions as 01:04:26.752 --> 01:04:29.924 well as class labs, he actually comes over 01:04:29.924 --> 01:04:33.828 and he listens and he also participates in our team 01:04:33.828 --> 01:04:36.065 discussions, gives all of like helpful advice 01:04:36.065 --> 01:04:40.340 as to like how do we really work on the project 01:04:40.340 --> 01:04:41.300 and how to build it. 01:04:41.300 --> 01:04:44.172 -So I have plan A, plan B, plan C, 01:04:44.172 --> 01:05:05.760 and plan D. That's how you have to live OK, so here we're 01:05:05.760 --> 01:05:07.810 on my email. 01:05:07.810 --> 01:05:11.650 -Jeffrey is-- you can barely tell Jeffrey's blind 01:05:11.650 --> 01:05:14.954 when he's at his place because he knows 01:05:14.954 --> 01:05:17.822 exactly where everything is. 01:05:17.822 --> 01:05:20.605 He's really passionate about technology. 01:05:20.605 --> 01:05:21.646 -He is really passionate. 01:05:21.646 --> 01:05:23.396 He told me that he as the coolest gadgets. 01:05:23.396 --> 01:05:24.270 -[INAUDIBLE]? 01:05:24.270 --> 01:05:24.861 -What toys? 01:05:24.861 --> 01:05:27.360 -You looked at this other wall while you were sitting there. 01:05:27.360 --> 01:05:28.721 I said, Jeff, what is it? 01:05:28.721 --> 01:05:29.304 -I don't know. 01:05:29.304 --> 01:05:31.248 -Remember, I said when I got here 01:05:31.248 --> 01:05:33.690 and he had this-- it's a talking thermometer. 01:05:33.690 --> 01:05:39.140 -Oh, it's a talking thermometer, indoor/outdoor temperature. 01:05:39.140 --> 01:05:42.445 Neil plays with it more than I do because, frankly, I 01:05:42.445 --> 01:05:44.127 don't give a damn. 01:05:44.127 --> 01:05:45.210 It's too much information. 01:05:49.422 --> 01:05:54.810 -The indoor temperature is 68.3 degrees Fahrenheit. 01:05:54.810 --> 01:05:56.450 -I don't even know how accurate it is. 01:05:56.450 --> 01:05:58.920 It's a toy. 01:05:58.920 --> 01:06:01.840 -And then he [? bought ?] this when he started cooking. 01:06:01.840 --> 01:06:05.110 It's a talking kitchen thermometer-- a kitchen scale. 01:06:05.110 --> 01:06:09.320 -Oh, yeah, I tell you, he knows more the toys-- I forgot. 01:06:09.320 --> 01:06:11.546 -Because I found them. 01:06:11.546 --> 01:06:12.524 -(SINGING) Ah-- 01:06:12.524 --> 01:06:13.491 -Ah. 01:06:13.491 --> 01:06:13.991 -Ah. 01:06:18.890 --> 01:06:20.122 [END PLAYBACK] 01:06:20.122 --> 01:06:22.330 JODIE CHEN: So here's some information about Jeffrey. 01:06:22.330 --> 01:06:24.540 So Jeffrey, he's visually impaired, 01:06:24.540 --> 01:06:27.800 and he has been kind of for his whole life. 01:06:27.800 --> 01:06:30.432 He used to be able to see like different things 01:06:30.432 --> 01:06:32.640 if you blew them up really large on like a projector. 01:06:32.640 --> 01:06:36.260 But now, all he can see is like just like light and darkness. 01:06:36.260 --> 01:06:38.790 So he's used computers for practically his whole, 01:06:38.790 --> 01:06:41.372 so he's actually very, very good at using his JAWS screen 01:06:41.372 --> 01:06:42.080 reading software. 01:06:42.080 --> 01:06:44.260 And he actually teaches people how 01:06:44.260 --> 01:06:46.650 to use it in the Carroll Center for the Blind. 01:06:46.650 --> 01:06:49.030 And he also knows braille, and he told us 01:06:49.030 --> 01:06:50.550 that actually a lot of blind people 01:06:50.550 --> 01:06:52.190 don't know how to read braille, so he's actually 01:06:52.190 --> 01:06:53.648 one of the few people that actually 01:06:53.648 --> 01:06:55.870 does know how to read braille. 01:06:55.870 --> 01:06:57.900 And he also does a lot of financial paperwork 01:06:57.900 --> 01:07:01.560 for his homeowner's association for his condo, 01:07:01.560 --> 01:07:03.850 and he does a lot of taxes for his friends. 01:07:03.850 --> 01:07:05.870 So he's constantly on his computer, 01:07:05.870 --> 01:07:09.105 checking his email, using Excel to work on that. 01:07:11.960 --> 01:07:15.310 So we kind of wanted to narrow down like an activity 01:07:15.310 --> 01:07:18.160 that Jeffrey has to do that he wants, I guess, like more help 01:07:18.160 --> 01:07:18.660 in. 01:07:18.660 --> 01:07:22.252 So he's a pretty opinionated person, 01:07:22.252 --> 01:07:24.460 so he already had an idea of what problems he exactly 01:07:24.460 --> 01:07:26.310 wanted us to solve and also solutions 01:07:26.310 --> 01:07:28.270 as to how to solve them. 01:07:28.270 --> 01:07:30.740 So on the activities that he kind of narrowed down 01:07:30.740 --> 01:07:34.890 for us is finding a way to sign a paper with a wet ink 01:07:34.890 --> 01:07:35.530 signature. 01:07:35.530 --> 01:07:39.330 So he gets a lot of financial sheets and documents from banks 01:07:39.330 --> 01:07:42.010 and stuff that need him to sign the document 01:07:42.010 --> 01:07:44.220 and not have a digital signature. 01:07:44.220 --> 01:07:45.725 So in order to sign a document, he 01:07:45.725 --> 01:07:47.910 has to have his visual aide Neil come over 01:07:47.910 --> 01:07:51.290 and like help him find the exact line where he has to sign. 01:07:51.290 --> 01:07:52.880 And if he doesn't have a visual aide, 01:07:52.880 --> 01:07:55.310 then there's no way for him to get that done. 01:07:55.310 --> 01:07:57.340 And she also uses Excel a lot, and he 01:07:57.340 --> 01:07:59.220 doesn't like the new format of Excel, 01:07:59.220 --> 01:08:01.320 so he wants us to kind of like change 01:08:01.320 --> 01:08:03.420 it to be more compatible with like the versions 01:08:03.420 --> 01:08:04.850 that he's used to. 01:08:04.850 --> 01:08:08.980 So we narrowed it down to being able to help 01:08:08.980 --> 01:08:12.880 him sign a document when he's like independent and alone, 01:08:12.880 --> 01:08:15.050 without a visual aide to help him. 01:08:15.050 --> 01:08:21.069 So to kind of get a better idea of what we have to work with, 01:08:21.069 --> 01:08:23.319 we kind of asked him like, what assistive technologies 01:08:23.319 --> 01:08:26.100 that he currently use so to find out 01:08:26.100 --> 01:08:28.550 which assistive technologies that he was comfortable with. 01:08:28.550 --> 01:08:32.390 So he told us that he's really comfortable with JAWS, 01:08:32.390 --> 01:08:37.000 and that like when he does OCR on a document, 01:08:37.000 --> 01:08:40.810 he can determine where a signature line is because JAWS 01:08:40.810 --> 01:08:43.970 will just say like, underscore, underscore, underscore. 01:08:43.970 --> 01:08:47.359 So all we had to do is kind of find a way 01:08:47.359 --> 01:08:49.850 to guide like his mouse pointer to like 01:08:49.850 --> 01:08:53.290 the position of the underline and then 01:08:53.290 --> 01:08:55.551 to find a way to convert that into like something 01:08:55.551 --> 01:08:57.509 that could be translated onto a piece of paper. 01:09:01.010 --> 01:09:05.160 So for our success metrics we kind of wanted 01:09:05.160 --> 01:09:07.470 to be able to evaluate like how well he 01:09:07.470 --> 01:09:11.029 can sign a document by seeing if he can actually find the place 01:09:11.029 --> 01:09:13.460 where to sign independently on his own, 01:09:13.460 --> 01:09:16.069 which he isn't able to do right now. 01:09:16.069 --> 01:09:18.330 And we also wanted to measure like how long it takes 01:09:18.330 --> 01:09:20.090 for him to measure a document. 01:09:20.090 --> 01:09:22.210 And I guess that's pretty easy to improve on 01:09:22.210 --> 01:09:24.662 because currently it takes infinite time for him to sign 01:09:24.662 --> 01:09:25.750 a document. 01:09:25.750 --> 01:09:27.220 And we also wanted to measure kind 01:09:27.220 --> 01:09:29.910 of how accurate he is with finding the position 01:09:29.910 --> 01:09:32.200 and also signing because we don't 01:09:32.200 --> 01:09:33.850 want him to sign somewhere that's 01:09:33.850 --> 01:09:36.160 really far away from the line. 01:09:36.160 --> 01:09:38.284 So that's kind of like the scope. 01:09:38.284 --> 01:09:39.700 YI TONG: So I'm just going to talk 01:09:39.700 --> 01:09:41.866 about the project organization, the progress so far. 01:09:45.620 --> 01:09:47.193 So the first is the ideation. 01:09:47.193 --> 01:09:49.359 So we're very lucky, so Jeffrey's always in the lab, 01:09:49.359 --> 01:09:50.830 as you all can see. 01:09:50.830 --> 01:09:52.790 So he's been meeting with us every lab 01:09:52.790 --> 01:09:55.000 and also contributes a lot of good ideas. 01:09:55.000 --> 01:09:58.590 So we go to the lab with ideas and then consult Jeffrey 01:09:58.590 --> 01:09:59.870 and ask him for the feedback. 01:09:59.870 --> 01:10:01.520 And then we narrow down the solutions 01:10:01.520 --> 01:10:02.970 after every discussion. 01:10:02.970 --> 01:10:06.750 And then finally, we decided on the mechi and software 01:10:06.750 --> 01:10:09.820 combined solution. 01:10:09.820 --> 01:10:12.410 So for the software part, so we all 01:10:12.410 --> 01:10:14.730 know that JAWS can detect a signature line 01:10:14.730 --> 01:10:17.540 and read out underscore and also like signatures 01:10:17.540 --> 01:10:18.860 and different kinds of words. 01:10:18.860 --> 01:10:21.485 So we just need to find a way to get coordinates from the mouse 01:10:21.485 --> 01:10:24.360 location, and then take in the mouse location two inches so 01:10:24.360 --> 01:10:27.970 that that can be the input for the mechi part. 01:10:27.970 --> 01:10:30.350 So for mechanical part, we need a frame 01:10:30.350 --> 01:10:33.270 the holds standard sized paper so it won't slide away. 01:10:33.270 --> 01:10:35.790 And then we need sliding braille rulers, or rails, 01:10:35.790 --> 01:10:40.310 to move horizontally and vertically so that Jeffrey can 01:10:40.310 --> 01:10:42.900 adjust to the exacty x-, y-coordinates by sliding 01:10:42.900 --> 01:10:45.150 the two rails. 01:10:45.150 --> 01:10:47.600 So here's the early sketches and also the prototype 01:10:47.600 --> 01:10:48.570 that we have. 01:10:48.570 --> 01:10:51.520 So on the right is just some white board drawings 01:10:51.520 --> 01:10:53.850 about different ideas that we had before. 01:10:53.850 --> 01:10:56.690 So the first one you can say something more or less like 01:10:56.690 --> 01:11:00.680 the magnifier that we see on [? Ability ?] [? Expo ?]. 01:11:00.680 --> 01:11:03.430 So basically the advantage of that is he 01:11:03.430 --> 01:11:07.390 doesn't have any restriction while he's signing things. 01:11:07.390 --> 01:11:10.080 But that is really hard to implement because the camera's 01:11:10.080 --> 01:11:12.420 on top of the paper. 01:11:12.420 --> 01:11:17.040 And also we also get inspired by the idea of a project built 01:11:17.040 --> 01:11:18.780 by an MIT Media Lab. 01:11:18.780 --> 01:11:22.175 So it's a finger reader, so like whenever he scans a line, 01:11:22.175 --> 01:11:23.050 he hears "signature." 01:11:23.050 --> 01:11:24.720 Then he will start signing. 01:11:24.720 --> 01:11:26.210 But then that would require Jeffrey 01:11:26.210 --> 01:11:28.410 to scan through the whole page. 01:11:28.410 --> 01:11:32.060 And then so we finalized on this sketch. 01:11:32.060 --> 01:11:34.330 So there are two siting rulers. 01:11:34.330 --> 01:11:37.230 Ideally, each ruler will have like brailles on it 01:11:37.230 --> 01:11:40.520 so that he can know how far he's gone on the page. 01:11:40.520 --> 01:11:44.150 So both rulers kind of slide left and right and also 01:11:44.150 --> 01:11:45.220 the other's up and down. 01:11:47.860 --> 01:11:50.230 Yeah and then just the idea-- you don't you read it. 01:11:50.230 --> 01:11:53.810 But it's just how much Jeffrey's input is given to us, 01:11:53.810 --> 01:11:56.290 and also he's really passionate about this project. 01:11:59.130 --> 01:12:02.360 DAVID KE: So this is the general timeline for what we're doing. 01:12:02.360 --> 01:12:03.860 So in the next few weeks, it's going 01:12:03.860 --> 01:12:06.661 to be focused on mostly making more prototypes 01:12:06.661 --> 01:12:08.160 for these projects, and we're really 01:12:08.160 --> 01:12:10.800 ramping up our interactions with Jeffrey 01:12:10.800 --> 01:12:13.604 to get feedback and iterate on our designs. 01:12:13.604 --> 01:12:15.520 So like as you've seen in the previous slides, 01:12:15.520 --> 01:12:17.322 we already have a really lo-fi prototype. 01:12:17.322 --> 01:12:19.280 So what we're going to do in the next two weeks 01:12:19.280 --> 01:12:22.890 is prepare multiple versions with minor detail differences 01:12:22.890 --> 01:12:25.210 to Jeffrey to see which ones he likes. 01:12:25.210 --> 01:12:27.460 Because a lot of it, the general idea is pretty solid, 01:12:27.460 --> 01:12:29.001 but a lot of it's like in the details 01:12:29.001 --> 01:12:30.960 of how unexpected things might come up 01:12:30.960 --> 01:12:32.930 as he uses it day to day. 01:12:32.930 --> 01:12:36.390 And in a few weeks, once we kind of have that hammered out, 01:12:36.390 --> 01:12:38.540 we'll try to work on like a more high fidelity 01:12:38.540 --> 01:12:40.351 prototype that this more closer to what 01:12:40.351 --> 01:12:42.850 we'll be presenting at the end in the beginning of November. 01:12:45.890 --> 01:12:50.346 And on the software side, this is more like on our side 01:12:50.346 --> 01:12:51.970 because we need to kind of get familiar 01:12:51.970 --> 01:12:54.630 with hows JAWS is working, as well as like what kind 01:12:54.630 --> 01:12:58.810 of inputs to outputs we can give to JAWS as well as from JAWS. 01:12:58.810 --> 01:13:02.186 And then we're aiming to sort of complete that little bit 01:13:02.186 --> 01:13:03.560 after hardware, so we can kind of 01:13:03.560 --> 01:13:06.143 combine it together and have a few weeks to see how that would 01:13:06.143 --> 01:13:07.740 work as a complete package. 01:13:10.960 --> 01:13:17.191 And this is just what we've done so far-- yay, teamwork. 01:13:17.191 --> 01:13:18.441 OK, and that's the last slide. 01:13:27.390 --> 01:13:30.380 YI TONG: Well, he obviously had a lot of ideas, 01:13:30.380 --> 01:13:34.560 and I'm wondering how you chose, or what 01:13:34.560 --> 01:13:37.820 process you used to choose this signature project? 01:13:37.820 --> 01:13:41.710 Was it sort of an embodiment of your skills and interests, 01:13:41.710 --> 01:13:45.170 or was it like clear front runner for him? 01:13:45.170 --> 01:13:47.580 DAVID KE: So I think two main categories 01:13:47.580 --> 01:13:49.250 we were considering in that was, one, 01:13:49.250 --> 01:13:52.280 is it something that aligned with our skills, 01:13:52.280 --> 01:13:56.190 because we're all studying computer science. 01:13:56.190 --> 01:13:57.940 He also had a bunch of projects that 01:13:57.940 --> 01:13:59.980 were pretty cool that wasn't that involved, 01:13:59.980 --> 01:14:01.960 like mostly mechanical engineering. 01:14:01.960 --> 01:14:04.530 So that was like a little out of the reach of our abilities. 01:14:04.530 --> 01:14:06.696 At the same time, something else we have to consider 01:14:06.696 --> 01:14:10.900 was we needed a project that was the right scope for the class. 01:14:10.900 --> 01:14:13.140 So like, for example, the Excel thing he mentioned, 01:14:13.140 --> 01:14:16.240 it's mostly computers, but it was very simple. 01:14:16.240 --> 01:14:19.231 So we wanted something that had more substance to it that 01:14:19.231 --> 01:14:21.022 could be applied to more people afterwards. 01:14:25.974 --> 01:14:28.390 PROFESSOR 1: I have a question about your baseline success 01:14:28.390 --> 01:14:32.980 metrics because you did say that signing documents is something 01:14:32.980 --> 01:14:35.860 does do with Neil's help. 01:14:35.860 --> 01:14:38.610 Have you watched him to do that with Niel's help? 01:14:38.610 --> 01:14:41.100 Have you sort of collected examples of his signature 01:14:41.100 --> 01:14:43.080 that he's done with Neils help? 01:14:43.080 --> 01:14:46.474 Seems like that you're not just operating with something 01:14:46.474 --> 01:14:47.890 that he's completely unable to do, 01:14:47.890 --> 01:14:50.960 but something he just can't do independently yet. 01:14:50.960 --> 01:14:53.460 JODIE CHEN: Well, he wants to be able to do it independently 01:14:53.460 --> 01:14:55.220 because Neil isn't always there. 01:14:55.220 --> 01:14:58.679 And we haven't really had a chance to watch Neil show him 01:14:58.679 --> 01:15:03.850 where the signature line is and how to sign it because, so far, 01:15:03.850 --> 01:15:07.081 we've only gone to his house once because he comes 01:15:07.081 --> 01:15:08.580 to Monday, Wednesday class sections, 01:15:08.580 --> 01:15:10.080 but also lab sections, so we've been 01:15:10.080 --> 01:15:13.090 meeting with him for around four hours 01:15:13.090 --> 01:15:14.972 every week during class time. 01:15:14.972 --> 01:15:16.930 DAVID KE: Yeah, but I think that's a good idea, 01:15:16.930 --> 01:15:18.688 and it's something we should definitely do 01:15:18.688 --> 01:15:20.630 the next time we meet with him. 01:15:20.630 --> 01:15:24.500 I suspect we'll have to consider that 01:15:24.500 --> 01:15:26.770 as like two different categories of like metrics, 01:15:26.770 --> 01:15:30.730 but it's something that should be included 01:15:30.730 --> 01:15:33.811 PROFESSOR 2: So I'm curious more about the mechanical aspect 01:15:33.811 --> 01:15:34.310 then. 01:15:34.310 --> 01:15:37.160 So you guys are really comfortable with the software 01:15:37.160 --> 01:15:39.634 side, and you presented the first prototype 01:15:39.634 --> 01:15:41.050 of the mechanical side, and you've 01:15:41.050 --> 01:15:44.990 showed kind of your sketch of how the camera might be there 01:15:44.990 --> 01:15:46.280 and where the rulers might be. 01:15:46.280 --> 01:15:48.113 But you talked about some of the limitations 01:15:48.113 --> 01:15:51.064 potentially for just being able to kind of look 01:15:51.064 --> 01:15:53.230 at where you put your head, where you put your hand. 01:15:53.230 --> 01:15:54.890 I want you to talk a little bit more 01:15:54.890 --> 01:15:56.950 about some of those limitations and things 01:15:56.950 --> 01:16:00.600 you're thinking about from the mechanical side, 01:16:00.600 --> 01:16:05.750 and what you think you might do to balance that. 01:16:05.750 --> 01:16:09.150 YI TONG: I think I might have misrepresented because I feel 01:16:09.150 --> 01:16:12.091 like the camera thing is just like the earlier prototypes 01:16:12.091 --> 01:16:14.590 that we explored, but we're not going to do the camera side. 01:16:14.590 --> 01:16:16.490 We're just going to keep the software part, 01:16:16.490 --> 01:16:17.840 the mechi part separate. 01:16:17.840 --> 01:16:20.036 So the mechi part is independent. 01:16:20.036 --> 01:16:21.410 It only takes in the coordinates. 01:16:21.410 --> 01:16:23.620 And then Jeffrey will get feedback 01:16:23.620 --> 01:16:26.390 when he's sliding the rulers, so he knows how far he's gone, 01:16:26.390 --> 01:16:29.240 but he doesn't have to have a camera take down 01:16:29.240 --> 01:16:31.320 where his hand is currently on. 01:16:31.320 --> 01:16:33.250 DAVID KE: Yeah, and one good thing about this 01:16:33.250 --> 01:16:36.090 is I think Jeffrey and us are pretty 01:16:36.090 --> 01:16:38.980 aligned in that we want to keep the amount 01:16:38.980 --> 01:16:42.540 of complicated components in the final project like minimized 01:16:42.540 --> 01:16:44.849 to reduce possibility of failure. 01:16:44.849 --> 01:16:46.390 So a lot of the things we've actually 01:16:46.390 --> 01:16:47.950 talked about in the past few weeks 01:16:47.950 --> 01:16:50.392 are ways to simplify the parts so that it still 01:16:50.392 --> 01:16:52.600 has the relevant information, but it's like as simple 01:16:52.600 --> 01:16:53.100 as possible. 01:16:56.015 --> 01:16:57.640 PROFESSOR 4: Any questions or comments? 01:16:57.640 --> 01:17:00.614 AUDIENCE: You mentioned using a mouse [INAUDIBLE]. 01:17:00.614 --> 01:17:03.030 But wouldn't that require him to click all over the screen 01:17:03.030 --> 01:17:05.356 to find out where the signature line is, or are you 01:17:05.356 --> 01:17:06.950 just going to have he reads through it with JAWS 01:17:06.950 --> 01:17:08.408 and then stops when he finds lines. 01:17:10.622 --> 01:17:12.830 JODIE CHEN: So it's more likely to be like the latter 01:17:12.830 --> 01:17:15.400 because he's done that. 01:17:15.400 --> 01:17:17.997 For JAWS, when JAWS is reading something on the screen, 01:17:17.997 --> 01:17:21.476 it has a [INAUDIBLE] somewhat similar [? to mouse clicks, ?] 01:17:21.476 --> 01:17:23.970 but they're not actually mouse [INAUDIBLE]. 01:17:23.970 --> 01:17:25.636 And then there's like a function in JAWS 01:17:25.636 --> 01:17:29.981 where it moves the mouse pointer to the location of where 01:17:29.981 --> 01:17:31.255 it's currently reading. 01:17:31.255 --> 01:17:32.963 So that's how we're planning on doing it. 01:17:36.939 --> 01:17:38.707 PROFESSOR 4: Any questions, comments? 01:17:38.707 --> 01:17:40.915 So quick clarification, so is there like a scanning-- 01:17:40.915 --> 01:17:41.412 maybe I missed it. 01:17:41.412 --> 01:17:43.400 Is there some scanning of the document first? 01:17:43.400 --> 01:17:45.388 Are you buying a scanner? 01:17:45.388 --> 01:17:47.429 JODIE CHEN: Oh, he always scans in his documents. 01:17:53.340 --> 01:17:56.224 AUDIENCE: I was hoping to [INAUDIBLE] Jeffrey briefly. 01:17:56.224 --> 01:17:58.807 Is it going to be an issue when the line is like a drawn line, 01:17:58.807 --> 01:18:01.292 as opposed to [INAUDIBLE] line? 01:18:01.292 --> 01:18:03.280 Or will that resolve with the scanner? 01:18:06.107 --> 01:18:08.690 DAVID KE: That just depends on like the of quality of the line 01:18:08.690 --> 01:18:13.179 as well as like the character recognition software. 01:18:13.179 --> 01:18:14.678 So we'll probably do tests with that 01:18:14.678 --> 01:18:16.678 to see like how much tolerance the software has. 01:18:19.125 --> 01:18:20.666 PROFESSOR 4: Michelle, last question. 01:18:20.666 --> 01:18:22.207 AUDIENCE: Is there a general location 01:18:22.207 --> 01:18:24.159 where you know the lines are going to be. 01:18:24.159 --> 01:18:26.277 Just out of curiosity, like if I sign a paper, 01:18:26.277 --> 01:18:28.151 it's usually at the bottom right-hand corner. 01:18:28.151 --> 01:18:29.149 Do you guys have an understanding 01:18:29.149 --> 01:18:31.190 of what kind of documents he's currently signing, 01:18:31.190 --> 01:18:32.749 like what they look like? 01:18:32.749 --> 01:18:35.040 YI TONG: According to Jeffrey, I think it varies a lot. 01:18:35.040 --> 01:18:37.860 And also sometimes like there's a huge line, 01:18:37.860 --> 01:18:41.580 but then the signature word is under the line, 01:18:41.580 --> 01:18:44.330 but sometimes it's just next to it. 01:18:44.330 --> 01:18:46.060 And then sometimes, the signature's 01:18:46.060 --> 01:18:48.252 right here on the left of page, but then you 01:18:48.252 --> 01:18:49.960 have to sign it to the right of the page. 01:18:49.960 --> 01:18:53.670 So it really depends on different kinds of paperwork. 01:18:53.670 --> 01:18:57.320 So we tried to collect all different kinds of paperwork 01:18:57.320 --> 01:18:59.080 that he normally gets, and then we 01:18:59.080 --> 01:19:03.080 tried to characterize like what different kinds of signature 01:19:03.080 --> 01:19:06.317 box that he normally gets and then work on that. 01:19:06.317 --> 01:19:07.900 JODIE CHEN: And also what Jeffrey does 01:19:07.900 --> 01:19:11.100 is he scans a document, and then he runs OCR on it, 01:19:11.100 --> 01:19:15.400 and then he translates it into a Word document, 01:19:15.400 --> 01:19:17.620 and then he prints out the Word document to sign. 01:19:17.620 --> 01:19:21.020 So what's going to happen is that he alters the document 01:19:21.020 --> 01:19:23.200 that he gets in mail pretty significantly when 01:19:23.200 --> 01:19:26.692 he runs OCR and changes it to a Word document. 01:19:26.692 --> 01:19:29.150 DAVID KE: But overall he gets a lot of different signatures 01:19:29.150 --> 01:19:31.855 on that. 01:19:31.855 --> 01:19:34.480 PROFESSOR 2: It would be really interesting to actually try out 01:19:34.480 --> 01:19:37.190 that and get those documents for all these different signature 01:19:37.190 --> 01:19:37.530 lines. 01:19:37.530 --> 01:19:39.113 And I think that's a really good point 01:19:39.113 --> 01:19:42.100 about whether it's an underscore line or a drawn line, 01:19:42.100 --> 01:19:45.196 and some signatures are actually boxes as opposed to lines 01:19:45.196 --> 01:19:46.404 and how that might affect it. 01:19:50.850 --> 01:19:52.021 PROFESSOR 4: OK, thank you. 01:20:01.812 --> 01:20:03.770 VYNNIE KONG: Everyone, we are Team Beverly Ann. 01:20:03.770 --> 01:20:05.482 This is our mid-semester review. 01:20:05.482 --> 01:20:06.190 My name's Vynnie. 01:20:06.190 --> 01:20:07.420 SHRUTHI NARAYANAN: I'm Shruthi. 01:20:07.420 --> 01:20:08.420 ROBERT LUO : I'm Robert. 01:20:12.310 --> 01:20:13.810 VYNNIE KONG: And we're just going 01:20:13.810 --> 01:20:17.160 to provide you a brief introduction to our client. 01:20:17.160 --> 01:20:19.350 So some of the non technical things-- Beverly-Ann 01:20:19.350 --> 01:20:22.400 is a social worker for DCF, so that's 01:20:22.400 --> 01:20:24.740 the Division of Children with Families, 01:20:24.740 --> 01:20:27.290 so she basically works at a sort of law firm. 01:20:27.290 --> 01:20:29.165 And she's actually learning how to code using 01:20:29.165 --> 01:20:32.180 and Scratch Arduino, which we thought were pretty cool. 01:20:32.180 --> 01:20:33.710 She loves playing Wi tennis. 01:20:33.710 --> 01:20:36.000 She has a backyard garden, so she 01:20:36.000 --> 01:20:37.820 grows tomatoes and marigolds. 01:20:37.820 --> 01:20:41.110 And most importantly, she wants to maintain an active mind 01:20:41.110 --> 01:20:43.790 in order to keep busy and kind of like 01:20:43.790 --> 01:20:46.730 find something useful for the rest of her life. 01:20:46.730 --> 01:20:49.630 And before we explain more about stuff 01:20:49.630 --> 01:20:51.390 related to the HAAT model, we think 01:20:51.390 --> 01:20:53.850 the video would be a very good descriptor 01:20:53.850 --> 01:20:55.598 of a lot of these things. 01:20:55.598 --> 01:20:59.990 [VIDEO PLAYBACK] 01:20:59.990 --> 01:21:02.870 -Hello, my name is Beverly Ann Rock, 01:21:02.870 --> 01:21:06.144 and I have been diagnosed with CMT, which 01:21:06.144 --> 01:21:07.435 stands for Charcot-Marie-Tooth. 01:21:20.660 --> 01:21:24.300 I was diagnosed about 11 years ago. 01:21:24.300 --> 01:21:26.440 If there's any blessings to this disease 01:21:26.440 --> 01:21:28.550 or anything good about this disease, is 01:21:28.550 --> 01:21:31.200 it only affects the hands and the legs, 01:21:31.200 --> 01:21:35.770 which means I'll always have my ability to talk. 01:21:35.770 --> 01:21:39.800 Three of my 10 fingers have taken on the deformity, which 01:21:39.800 --> 01:21:41.360 means they're kind of locked. 01:21:41.360 --> 01:21:45.220 And eventually, they will end up in gnarled positions. 01:21:45.220 --> 01:21:49.900 But fortunately, 7 is better than none. 01:21:49.900 --> 01:21:53.660 So I use my seven fingers very effectively. 01:21:53.660 --> 01:21:59.970 My right hand, it has become numb in many places. 01:21:59.970 --> 01:22:02.510 Thus it doesn't give me the opportunity 01:22:02.510 --> 01:22:06.610 to use very simple devices. 01:22:06.610 --> 01:22:10.290 So if I were to be trying to drink something hot, 01:22:10.290 --> 01:22:13.590 I would make sure to try to grip it as best I can 01:22:13.590 --> 01:22:15.760 and support it. 01:22:15.760 --> 01:22:18.932 But over time, it's not going to hold. 01:22:18.932 --> 01:22:20.890 It's going to slip, I'm going to lose the grip. 01:22:26.580 --> 01:22:29.610 That's one of my concerns is dropping stuff 01:22:29.610 --> 01:22:32.990 and why I'm so guarded about dropping 01:22:32.990 --> 01:22:39.240 is if you drop a glass, a shard, I had a couple times, 01:22:39.240 --> 01:22:41.490 a little thing has just stuck into my foot, 01:22:41.490 --> 01:22:45.230 and I didn't realize it till I looked down and said, 01:22:45.230 --> 01:22:46.810 why am I bleeding? 01:22:46.810 --> 01:22:54.450 I Constantly fall, and I always have devices or walkers 01:22:54.450 --> 01:22:57.060 or scooters or things that will enable 01:22:57.060 --> 01:23:00.268 me to maintain balance and continue to be mobile. 01:23:03.730 --> 01:23:06.620 I choose, at this point in my life, to work, 01:23:06.620 --> 01:23:08.671 even though I'm at retirement age, 01:23:08.671 --> 01:23:10.836 and that's because it keeps my mind busy. 01:23:13.730 --> 01:23:18.220 And hopefully every day they're working on a cure, 01:23:18.220 --> 01:23:20.870 or I stumble on a program like you 01:23:20.870 --> 01:23:26.060 that is going to assist me to make things a little easier. 01:23:26.060 --> 01:23:29.020 So if I had a device that was telling me, 01:23:29.020 --> 01:23:30.860 if I got too into the conversation, 01:23:30.860 --> 01:23:33.466 that it's loosening, then I when know to go back and not 01:23:33.466 --> 01:23:40.394 use the assistance to go back and try to tighten the grip. 01:23:40.394 --> 01:23:41.810 -We have to distract you some how. 01:23:41.810 --> 01:23:43.935 -You are distracting me because why you're talking, 01:23:43.935 --> 01:23:45.600 I'm saying, OK, hold on. 01:23:53.879 --> 01:23:57.790 [END PLAYBACK] 01:23:57.790 --> 01:24:02.220 SHRUTHI NARAYANAN: So, as she said in the video, she has CMT. 01:24:02.220 --> 01:24:03.770 It's a neurodegenerative disease that 01:24:03.770 --> 01:24:07.660 affects the extremities, so the hands and the feet. 01:24:07.660 --> 01:24:10.970 It results in a loss of touch sensation and muscle control. 01:24:10.970 --> 01:24:13.170 So she has involuntary muscle spasms. 01:24:13.170 --> 01:24:15.685 For her, in particular, we're interested in her hands. 01:24:15.685 --> 01:24:18.310 So it means that she has sensory failures in part of your hands 01:24:18.310 --> 01:24:21.030 and muscle failure in others. 01:24:21.030 --> 01:24:23.890 And this is like a general diagram 01:24:23.890 --> 01:24:25.880 of her left and right hand. 01:24:25.880 --> 01:24:29.430 On her left hand, you can see the green fingers are curled in 01:24:29.430 --> 01:24:30.450 like this. 01:24:30.450 --> 01:24:32.820 And that's because that's their natural position. 01:24:32.820 --> 01:24:34.903 So when she tries to open them, they automatically 01:24:34.903 --> 01:24:35.580 curl back in. 01:24:35.580 --> 01:24:38.160 So this is like the involuntary muscle movement. 01:24:38.160 --> 01:24:40.960 But her other two fingers are very mobile. 01:24:40.960 --> 01:24:42.980 So even though she can't grip anything just 01:24:42.980 --> 01:24:44.840 with the left hand, she uses her left hand 01:24:44.840 --> 01:24:46.880 to support what she's gripping a lot. 01:24:46.880 --> 01:24:49.364 On her right hand, the red regions, 01:24:49.364 --> 01:24:50.780 which are most of her fingers, are 01:24:50.780 --> 01:24:52.760 the places where her hands are numb, 01:24:52.760 --> 01:24:55.020 so she can't feel anything. 01:24:55.020 --> 01:24:56.760 And so she has a hard time gripping 01:24:56.760 --> 01:24:58.250 with those parts of her fingers. 01:24:58.250 --> 01:25:01.740 But the tips of her fingertips, which are marked in blue, 01:25:01.740 --> 01:25:03.310 are actually fully sensitive. 01:25:03.310 --> 01:25:06.680 So she tends to claw whenever she's picking things up. 01:25:06.680 --> 01:25:10.650 But over time, she still loses grip with her right hand. 01:25:13.195 --> 01:25:14.820 VYNNIE KONG: Because of the combination 01:25:14.820 --> 01:25:19.560 of loss of pressure and also involuntary muscle movements, 01:25:19.560 --> 01:25:22.500 there are certain activities that Beverly Ann has trouble 01:25:22.500 --> 01:25:23.800 with on a day-to-day basis. 01:25:23.800 --> 01:25:26.630 And then I made a table with modifications 01:25:26.630 --> 01:25:28.650 that she's learned to do to adapt. 01:25:28.650 --> 01:25:31.306 So a lot of the things she has trouble with 01:25:31.306 --> 01:25:34.167 is having to consciously think about doing 01:25:34.167 --> 01:25:35.000 everything she does. 01:25:35.000 --> 01:25:38.250 So any time she has to pick up something to drink of water, 01:25:38.250 --> 01:25:39.730 any time she has to type something, 01:25:39.730 --> 01:25:42.440 she needs to think about every single letter she types, 01:25:42.440 --> 01:25:45.650 rather than just typing out of muscle memory. 01:25:45.650 --> 01:25:48.321 And that's difficult, especially when 01:25:48.321 --> 01:25:50.070 you're holding a conversation with someone 01:25:50.070 --> 01:25:52.630 or if you're just thinking about something else. 01:25:52.630 --> 01:25:55.460 You can't always think about what you're doing all the time. 01:25:55.460 --> 01:25:58.080 This also helps with walking down stairwells, 01:25:58.080 --> 01:26:00.880 because she has to grip onto the stairwell 01:26:00.880 --> 01:26:04.050 and make sure she squeezes every couple of seconds, 01:26:04.050 --> 01:26:07.570 so if she's managed to stumble, she'll still have the grip 01:26:07.570 --> 01:26:09.202 and be able to stabilize herself. 01:26:09.202 --> 01:26:11.660 And the last thing is actually cooking, which he brought up 01:26:11.660 --> 01:26:15.410 in a meeting, where she realized when she was cooking potatoes 01:26:15.410 --> 01:26:18.140 and she was picking up potatoes to put them in the pot 01:26:18.140 --> 01:26:20.627 that she wasn't actually grabbing on to them. 01:26:20.627 --> 01:26:22.710 So she had to use this sort of like clawing motion 01:26:22.710 --> 01:26:25.750 to get them from the cutting board into the pot. 01:26:29.225 --> 01:26:31.600 ROBERT LUO : So the basic problem we're dealing with here 01:26:31.600 --> 01:26:35.360 is that she has to constantly think about the things 01:26:35.360 --> 01:26:38.590 she's grabbing whenever she's grabbing some kind of object. 01:26:38.590 --> 01:26:42.800 And also, she is not really confident in using 01:26:42.800 --> 01:26:46.190 just her right hand for grabbing objects. 01:26:46.190 --> 01:26:50.360 Instead she normally uses her left hand to do the support. 01:26:50.360 --> 01:26:54.720 And we want to come up with the device which would help her 01:26:54.720 --> 01:26:59.420 by notifying her when she first-- helping her to have 01:26:59.420 --> 01:27:03.010 the confidence to grab objects with just her right hand, 01:27:03.010 --> 01:27:08.960 and then notifying her whenever her gripping starts to become 01:27:08.960 --> 01:27:11.110 loose. 01:27:11.110 --> 01:27:14.390 So then we came up with the success metrics 01:27:14.390 --> 01:27:15.300 for our project. 01:27:15.300 --> 01:27:17.930 There are few things we can think about. 01:27:17.930 --> 01:27:25.230 So the first thing is we want to see how much of a percentage 01:27:25.230 --> 01:27:27.630 our device could give her the warning. 01:27:27.630 --> 01:27:29.750 So right now, of course, it's zero. 01:27:29.750 --> 01:27:32.930 But we think a reasonable goal will 50%. 01:27:32.930 --> 01:27:35.600 Meaning that our device will be able to alert 01:27:35.600 --> 01:27:39.730 her 50% of the time whenever her grip starts to become loose, 01:27:39.730 --> 01:27:42.490 and then with an ambitious goal of 90%. 01:27:42.490 --> 01:27:44.520 And then the second success metric 01:27:44.520 --> 01:27:47.890 is the dropping rate with just her right hand. 01:27:47.890 --> 01:27:51.850 And so this part we still need to measure how many times, 01:27:51.850 --> 01:27:54.510 how many things she drops on average in a day, 01:27:54.510 --> 01:27:56.270 and then we want to decrease that 01:27:56.270 --> 01:28:03.400 by 50% as our reasonable goal, and 20% off the original 01:28:03.400 --> 01:28:05.340 as our ambitious goal. 01:28:05.340 --> 01:28:08.850 And then we want to boost her confidence in gripping objects 01:28:08.850 --> 01:28:10.800 with just her right hand. 01:28:10.800 --> 01:28:15.510 And we can measure how many times 01:28:15.510 --> 01:28:19.100 she grabs things in a weekly basis or a daily basis. 01:28:19.100 --> 01:28:23.280 And then we want to increase the percentage of her just 01:28:23.280 --> 01:28:27.530 using her the right hand to grab to 60%, then eventually 90%. 01:28:31.160 --> 01:28:36.380 And so this is our design process for this device. 01:28:36.380 --> 01:28:38.410 So first, we define the goals. 01:28:38.410 --> 01:28:41.200 So we noticed that she has two different problems 01:28:41.200 --> 01:28:42.970 for her left hand and her right hand. 01:28:42.970 --> 01:28:45.380 And after talking with our mentor Jeff, 01:28:45.380 --> 01:28:47.560 we decided to focus on solving her problem 01:28:47.560 --> 01:28:50.740 with the right hand, so meaning the gripping part. 01:28:50.740 --> 01:28:53.270 Then we brainstormed of different ideas. 01:28:53.270 --> 01:28:55.690 We mainly focused on whether we should use a sensor, 01:28:55.690 --> 01:28:58.440 and if yes, where should we put the sensor 01:28:58.440 --> 01:29:03.510 as well as how we can attach the sensor to her hand? 01:29:03.510 --> 01:29:07.580 Then we come with various types of prototypes, 01:29:07.580 --> 01:29:10.320 many based on the location of the sensor 01:29:10.320 --> 01:29:14.620 as well as the style of attachment of the sensor. 01:29:14.620 --> 01:29:17.390 So the fundamental idea of our design 01:29:17.390 --> 01:29:21.870 is to have a way to quantify the pressures she exercises when 01:29:21.870 --> 01:29:24.110 she grabs things as well as trying 01:29:24.110 --> 01:29:27.860 to have a way to notify her when her grip becomes loose. 01:29:30.394 --> 01:29:32.310 SHRUTHI NARAYANAN: So the first concept we had 01:29:32.310 --> 01:29:34.730 was to place the sensors near the palm of her right hand, 01:29:34.730 --> 01:29:36.110 so that would be in this area. 01:29:36.110 --> 01:29:38.000 We figured that we wanted as little material 01:29:38.000 --> 01:29:40.580 on her hand as possible, so it wouldn't weigh her down and so 01:29:40.580 --> 01:29:42.800 that it wouldn't look like a very obvious device. 01:29:42.800 --> 01:29:44.180 And then on the back of the hand, 01:29:44.180 --> 01:29:45.388 you can see there's a square. 01:29:45.388 --> 01:29:47.280 That would be where the sensors read out to. 01:29:47.280 --> 01:29:48.480 There would be some sort of output 01:29:48.480 --> 01:29:50.640 there that she could look or that would notify her 01:29:50.640 --> 01:29:51.950 when her grip is slipping. 01:29:51.950 --> 01:29:54.694 So this was good because it was very small and condensed, 01:29:54.694 --> 01:29:56.360 and she'd still have use of her fingers. 01:29:56.360 --> 01:29:58.760 But it was bad because she tends to grip with her fingertips. 01:29:58.760 --> 01:30:01.210 So we wouldn't actually be able to sense a lot of the grip 01:30:01.210 --> 01:30:02.480 that she was using. 01:30:02.480 --> 01:30:06.007 And so we would basically get no reading most of the time 01:30:06.007 --> 01:30:07.840 So then we came up with an exciting concept, 01:30:07.840 --> 01:30:10.280 which was to place the sensors on the tips of the fingers. 01:30:10.280 --> 01:30:12.530 If you can see, everything except for the index finger 01:30:12.530 --> 01:30:13.646 has a sensor. 01:30:13.646 --> 01:30:16.020 That's because she actually doesn't use your index finger 01:30:16.020 --> 01:30:17.050 very much when gripping. 01:30:17.050 --> 01:30:19.429 So the other four fingers have sensors. 01:30:19.429 --> 01:30:20.970 They wrap around the back of the hand 01:30:20.970 --> 01:30:23.301 to go to the same output box. 01:30:23.301 --> 01:30:25.800 This is much better because she grips with their fingertips, 01:30:25.800 --> 01:30:27.758 so we can actually sense what's she's gripping. 01:30:27.758 --> 01:30:30.790 But it does take up more of her hand. 01:30:30.790 --> 01:30:32.590 In the end, we went with a second concept, 01:30:32.590 --> 01:30:35.455 and this is because we asked her about how she felt about having 01:30:35.455 --> 01:30:36.330 a device on her hand. 01:30:36.330 --> 01:30:38.462 And she was like, I don't care what it looks like. 01:30:38.462 --> 01:30:40.920 It could be pretty big, and I would be OK with that as long 01:30:40.920 --> 01:30:42.460 as it helps me to grip. 01:30:42.460 --> 01:30:46.492 So we made some very basic prototypes of just the shape 01:30:46.492 --> 01:30:47.700 of what they would look like. 01:30:47.700 --> 01:30:51.610 So the sensors are the sort of strips of paper, 01:30:51.610 --> 01:30:53.380 and we just wanted to see how they 01:30:53.380 --> 01:30:58.775 would look so that we can sort of experiment with how 01:30:58.775 --> 01:30:59.650 they fit on her hand. 01:30:59.650 --> 01:31:01.105 So if you want to-- 01:31:04.020 --> 01:31:06.340 VYNNIE KONG: So a bit of a future timeline, 01:31:06.340 --> 01:31:10.530 we are planning by next week, so October 29th, to start 01:31:10.530 --> 01:31:12.280 and basically finished figuring out 01:31:12.280 --> 01:31:15.100 the circuitry for connecting these sensors to some sort 01:31:15.100 --> 01:31:18.020 of output voltage, and we want to tune the circuit so 01:31:18.020 --> 01:31:20.830 that whatever output voltage the sensors produce 01:31:20.830 --> 01:31:24.385 will be in a format that's interpretable to our needs. 01:31:26.645 --> 01:31:28.520 SHRUTHI NARAYANAN: Then we want to write code 01:31:28.520 --> 01:31:29.978 to respond to the sensor so that we 01:31:29.978 --> 01:31:33.110 can give her a sort of output on when she's losing grip. 01:31:33.110 --> 01:31:36.060 So we want to study what the sensor voltage looks 01:31:36.060 --> 01:31:38.870 like as her grip loosens and try to figure out 01:31:38.870 --> 01:31:40.950 where we can start notifying her, 01:31:40.950 --> 01:31:43.770 when like this certain thing happens that, oh, your grip is 01:31:43.770 --> 01:31:44.380 loosening. 01:31:44.380 --> 01:31:46.790 So we plan to try multiple different algorithms for this, 01:31:46.790 --> 01:31:48.790 and this will hopefully be our second prototype, 01:31:48.790 --> 01:31:52.390 and we'll have it done by the first week of November. 01:31:52.390 --> 01:31:54.870 ROBERT LUO : And then the third step is the actual glove we 01:31:54.870 --> 01:31:57.310 will use to attach the sensor with. 01:31:57.310 --> 01:32:00.230 So some things we want to think about in this stage 01:32:00.230 --> 01:32:03.320 is how we want to keep the sensors safe, which 01:32:03.320 --> 01:32:05.780 means we don't want the sensors to be 01:32:05.780 --> 01:32:08.030 exposed to the outside environment as well 01:32:08.030 --> 01:32:08.850 as her hand. 01:32:08.850 --> 01:32:10.550 So maybe something we're thinking about 01:32:10.550 --> 01:32:13.240 is knitting two layers of the gloves 01:32:13.240 --> 01:32:16.310 together and having the sensors to be in the middle. 01:32:16.310 --> 01:32:19.700 So that could protect the sensor from the outside environment 01:32:19.700 --> 01:32:20.550 as well as her hand. 01:32:20.550 --> 01:32:24.320 And then we also want to think about questions like, 01:32:24.320 --> 01:32:27.280 what happens to the sensors when she curls her hand? 01:32:27.280 --> 01:32:30.170 So the way we think about it is that as long 01:32:30.170 --> 01:32:32.300 as we put the sensor on the back of her hand 01:32:32.300 --> 01:32:35.220 or on the wristband, it depends on which one 01:32:35.220 --> 01:32:36.860 we choose eventually. 01:32:36.860 --> 01:32:40.070 Both designs would able to help stable, even 01:32:40.070 --> 01:32:41.170 when she curls her hand. 01:32:47.030 --> 01:32:49.780 And, of course, after we're having the prototypes, 01:32:49.780 --> 01:32:54.420 we want to keep improving on the device based on our test 01:32:54.420 --> 01:32:55.850 results with Beverly Ann. 01:32:58.350 --> 01:33:00.600 VYNNIE KONG: A little bit about our division of work-- 01:33:00.600 --> 01:33:03.310 so during our client meetings, Shruthi 01:33:03.310 --> 01:33:04.940 he has been primarily doing the video. 01:33:04.940 --> 01:33:07.023 I've been primarily doing the interviews, and then 01:33:07.023 --> 01:33:07.850 Robert, the notes. 01:33:07.850 --> 01:33:10.510 And looking onwards, Shruthi and I 01:33:10.510 --> 01:33:11.970 will be planning on working mostly 01:33:11.970 --> 01:33:14.530 on the circuits, and then Robert on most of the gloves 01:33:14.530 --> 01:33:18.012 and figuring out what materials to use. 01:33:18.012 --> 01:33:19.470 And thank you, guys, for listening. 01:33:19.470 --> 01:33:21.095 If you have any questions, let us know. 01:33:27.496 --> 01:33:30.472 PROFESSOR 4: Questions comments from [INAUDIBLE]? 01:33:30.472 --> 01:33:32.180 PROFESSOR 1: I'm wondering if you thought 01:33:32.180 --> 01:33:34.500 about what you might do passively 01:33:34.500 --> 01:33:38.200 with the material of the glove to make it 01:33:38.200 --> 01:33:40.390 less likely that it would slip? 01:33:40.390 --> 01:33:41.265 You know what I mean? 01:33:41.265 --> 01:33:43.350 You have a very active solution right now 01:33:43.350 --> 01:33:47.382 that depends on sensors and electronics and batteries. 01:33:47.382 --> 01:33:49.090 Are there anymore passive things that you 01:33:49.090 --> 01:33:50.650 might do, either with material or with the design 01:33:50.650 --> 01:33:52.157 of the glove, or have you thought 01:33:52.157 --> 01:33:53.365 about that part of the space? 01:33:57.739 --> 01:33:59.530 SHRUTHI NARAYANAN: So one of the big things 01:33:59.530 --> 01:34:02.540 we thought about was when we get the material for designing 01:34:02.540 --> 01:34:04.230 the glove, to have like sort of grip. 01:34:04.230 --> 01:34:06.800 So certain gloves do come with like rubber 01:34:06.800 --> 01:34:09.036 on the outside of them to have more grip, 01:34:09.036 --> 01:34:10.660 and we thought that something like this 01:34:10.660 --> 01:34:12.350 would also be able to help her generally 01:34:12.350 --> 01:34:14.240 keep her grip on slippery objects, 01:34:14.240 --> 01:34:15.520 especially with the glove on. 01:34:15.520 --> 01:34:18.190 So that's one example of a passive solution. 01:34:18.190 --> 01:34:21.540 We did think of entirely passive solutions at the beginning, 01:34:21.540 --> 01:34:23.249 like having some sort of exoskeleton that 01:34:23.249 --> 01:34:25.290 would like hold her group in place that she could 01:34:25.290 --> 01:34:26.750 lock into place or something. 01:34:26.750 --> 01:34:30.890 But we figured that then she'd be having to manipulate 01:34:30.890 --> 01:34:32.430 the device too much herself. 01:34:32.430 --> 01:34:34.780 And so we went with the more active solution in general. 01:34:34.780 --> 01:34:37.240 But yes, smaller passive things, like the rubber grips 01:34:37.240 --> 01:34:40.390 and having some fingers open so that she has better grip, 01:34:40.390 --> 01:34:42.967 will hopefully help her with her grip anyways. 01:34:42.967 --> 01:34:44.550 VYNNIE KONG: And we actually found out 01:34:44.550 --> 01:34:47.740 that a lot of her problems don't come from muscular strength. 01:34:47.740 --> 01:34:50.150 So it's not that she can't physically lift the plate. 01:34:50.150 --> 01:34:53.850 It's just that she can't feel how hard she's gripping it. 01:34:53.850 --> 01:34:56.450 So balancing it becomes a bit of an issue, for example. 01:35:01.715 --> 01:35:03.840 PROFESSOR 5: Well, following on what you just said, 01:35:03.840 --> 01:35:06.506 did you think of any sort of way of giving 01:35:06.506 --> 01:35:08.390 maybe auditory feedback or some way 01:35:08.390 --> 01:35:13.450 to in terms of the gripping, like is there a user interface 01:35:13.450 --> 01:35:14.660 aspect to this? 01:35:14.660 --> 01:35:16.970 ROBERT LUO : Right, so some things we think about is 01:35:16.970 --> 01:35:20.710 so after having a sensors, we want to be able to quantify her 01:35:20.710 --> 01:35:21.210 grip. 01:35:21.210 --> 01:35:24.020 And so some things we are thinking about 01:35:24.020 --> 01:35:28.350 is we can test how much of a grip she exercises on an object 01:35:28.350 --> 01:35:30.550 initially, and then set that as a threshold. 01:35:30.550 --> 01:35:34.110 And whenever the grip comes down to 50% of the original grip, 01:35:34.110 --> 01:35:36.740 then that's the threshold we think of warning her. 01:35:36.740 --> 01:35:38.990 And then and then the ways of warning her 01:35:38.990 --> 01:35:42.080 include having a beeping sound, or it vibrates 01:35:42.080 --> 01:35:44.925 so she will be notified. 01:35:44.925 --> 01:35:47.571 PROFESSOR 5: Did you think about cost? 01:35:47.571 --> 01:35:49.070 Did you say cost, like what it would 01:35:49.070 --> 01:35:52.240 cost to make one of these in quantity or something? 01:35:52.240 --> 01:35:55.950 ROBERT LUO : Oh, right, so we already have the sensors ready. 01:35:55.950 --> 01:35:58.660 So we already got the sensors, so they were not too expensive. 01:35:58.660 --> 01:36:00.750 They were $60, $70. 01:36:00.750 --> 01:36:03.250 And then we know are on the stage of figuring out 01:36:03.250 --> 01:36:05.910 how the circuits would work, and we would approach it 01:36:05.910 --> 01:36:08.840 by making it on a breadboard first, 01:36:08.840 --> 01:36:12.360 then thinking of whether it's possible to make 01:36:12.360 --> 01:36:14.310 this circuits into a smaller circuit board 01:36:14.310 --> 01:36:15.700 and attaching it to the glove. 01:36:15.700 --> 01:36:17.450 And then the glove itself shouldn't really 01:36:17.450 --> 01:36:20.115 be that expensive. 01:36:20.115 --> 01:36:22.240 PROFESSOR 5: Any quick questions from the audience? 01:36:25.356 --> 01:36:27.037 AUDIENCE: [INAUDIBLE]? 01:36:27.037 --> 01:36:28.078 VYNNIE KONG: We have not. 01:36:28.078 --> 01:36:28.620 What is that? 01:36:28.620 --> 01:36:30.661 AUDIENCE: Oh, it's like thread that's in buckets, 01:36:30.661 --> 01:36:32.410 so it's like a wire, but it's thread. 01:36:32.410 --> 01:36:33.243 [INTERPOSING VOICES] 01:36:35.866 --> 01:36:37.740 SHRUTHI NARAYANAN: Yeah, I guess like once we 01:36:37.740 --> 01:36:39.600 have the sensors attached inside the glove 01:36:39.600 --> 01:36:41.885 to get it to the output, we could use that. 01:36:41.885 --> 01:36:43.050 Thank you for the idea. 01:36:50.680 --> 01:36:53.130 STUDENT 1: Hi, we're team Barbara. 01:36:53.130 --> 01:36:54.080 So this is Barbara. 01:36:54.080 --> 01:36:56.430 She has been a teacher for 29 years, 01:36:56.430 --> 01:36:59.910 but she had to retire early because she has PLS. 01:36:59.910 --> 01:37:02.350 So PLS is kind of like ALS. 01:37:02.350 --> 01:37:05.420 It's a disease where your muscles get weaker. 01:37:05.420 --> 01:37:08.700 And right now she is living in the Leonard Florence Center, 01:37:08.700 --> 01:37:10.940 and she really values independence. 01:37:10.940 --> 01:37:15.110 And as of right now, she has fine motor skills in her hands, 01:37:15.110 --> 01:37:18.230 but is slowly losing her strength, especially 01:37:18.230 --> 01:37:20.240 in her left hand because she does 01:37:20.240 --> 01:37:23.840 a lot of crocheting during her free time, which keeps 01:37:23.840 --> 01:37:27.650 her right hand more flexible. 01:37:27.650 --> 01:37:30.510 And she's also constrained to a wheelchair, 01:37:30.510 --> 01:37:33.500 and her speech is sometimes unclear 01:37:33.500 --> 01:37:36.808 because the muscles in her face are also weakening. 01:37:41.210 --> 01:37:44.060 So some of the activities that she has trouble with 01:37:44.060 --> 01:37:46.670 is opening and closing the door in her room. 01:37:46.670 --> 01:37:49.170 This is her door. 01:37:49.170 --> 01:37:53.860 And it's difficult for because the door is very heavy, 01:37:53.860 --> 01:37:57.850 and also it does not swing open. 01:37:57.850 --> 01:38:00.790 When she's trying to open it, it stays where you 01:38:00.790 --> 01:38:03.370 leave it and locks in place. 01:38:03.370 --> 01:38:05.820 Also, because her wheelchair gets in the way 01:38:05.820 --> 01:38:08.050 because the door opens towards her, 01:38:08.050 --> 01:38:09.549 so she has to open it a little bit. 01:38:09.549 --> 01:38:11.340 scoot her chair back, and then open it some 01:38:11.340 --> 01:38:14.280 more, which makes it very difficult. 01:38:14.280 --> 01:38:16.460 Another problem that she has is turning off 01:38:16.460 --> 01:38:19.360 the lights before she goes to sleep because once she's 01:38:19.360 --> 01:38:21.680 in bed, it's very difficult for her to get up 01:38:21.680 --> 01:38:22.680 and turn off the lights. 01:38:24.700 --> 01:38:29.450 Currently, she has an iPhone, and on her iPhone, 01:38:29.450 --> 01:38:31.150 these are some of the apps that she 01:38:31.150 --> 01:38:34.100 uses for assistive technology. 01:38:34.100 --> 01:38:37.100 The ones on the bottom here, some 01:38:37.100 --> 01:38:39.900 are for speaking because her speech is unclear. 01:38:39.900 --> 01:38:42.930 So, for example, there's one for her to say yes or no, 01:38:42.930 --> 01:38:45.440 and some of them where she can type in phrases, 01:38:45.440 --> 01:38:47.530 and it'll speak it for her. 01:38:47.530 --> 01:38:51.590 Or there's also apps for her to indicate the amount of pain 01:38:51.590 --> 01:38:53.020 she has right now. 01:38:53.020 --> 01:38:55.450 She also recently got an iPad, but she 01:38:55.450 --> 01:38:57.870 hasn't been using it that much because it's heavy. 01:38:57.870 --> 01:38:59.890 But she has no assistive technology 01:38:59.890 --> 01:39:02.360 that she uses currently for opening the door 01:39:02.360 --> 01:39:03.480 or turning out the lights. 01:39:06.580 --> 01:39:10.080 So some of the context is that her room is right next 01:39:10.080 --> 01:39:12.390 to the dining area, so sometimes there's 01:39:12.390 --> 01:39:14.560 a lot of noise that bothers her. 01:39:14.560 --> 01:39:16.520 Also, she has concern for privacy 01:39:16.520 --> 01:39:18.580 because since the door is so hard to open, 01:39:18.580 --> 01:39:20.830 she leaves it open most of the time. 01:39:20.830 --> 01:39:23.770 And right now, the staff at the Leonard Florence Center 01:39:23.770 --> 01:39:25.860 has to open and close the door for every day 01:39:25.860 --> 01:39:28.740 and turn on and off the lights. 01:39:28.740 --> 01:39:32.610 And although she didn't ask for a solution for her voice 01:39:32.610 --> 01:39:34.830 problem, she did tell us that this 01:39:34.830 --> 01:39:37.230 is a major concern for her. 01:39:37.230 --> 01:39:40.230 So based on my contextual inquiry, 01:39:40.230 --> 01:39:42.440 we decided on our project, which is 01:39:42.440 --> 01:39:44.802 to automate the door because she really 01:39:44.802 --> 01:39:47.260 wants to have the independence to be able to open and close 01:39:47.260 --> 01:39:50.310 the door by herself, and also have privacy in her room, 01:39:50.310 --> 01:39:53.030 and she doesn't currently have any assistive technology 01:39:53.030 --> 01:39:53.830 for that. 01:39:53.830 --> 01:39:56.230 And that is like the most difficult problem for her right 01:39:56.230 --> 01:39:56.730 now. 01:39:59.260 --> 01:40:03.140 So for success metrics we think the best possible solution 01:40:03.140 --> 01:40:05.270 would be for her to have an app on her phone 01:40:05.270 --> 01:40:08.190 that she would just be able to click or some sensors, 01:40:08.190 --> 01:40:11.920 so she doesn't have to actually opened the door. 01:40:11.920 --> 01:40:14.896 And a less successful solution would be for her 01:40:14.896 --> 01:40:18.440 to press a button and something that would just 01:40:18.440 --> 01:40:20.690 be able to reduce the amount of effort she needs 01:40:20.690 --> 01:40:23.517 is to have her pull something that would then open the door, 01:40:23.517 --> 01:40:25.350 instead of actually opening the door itself. 01:40:27.402 --> 01:40:29.110 STUDENT 2: So next we're going to explain 01:40:29.110 --> 01:40:33.167 a little bit about our ideation process for this door. 01:40:33.167 --> 01:40:34.750 So we're going to start by showing you 01:40:34.750 --> 01:40:39.460 a video of our design process and to give you a bit of sense. 01:40:39.460 --> 01:40:40.380 [VIDEO PLAYBACK] 01:40:40.380 --> 01:40:43.790 -This place, the Leonard Florence Center, is wonderful. 01:40:43.790 --> 01:40:50.960 They encourage you to be independent the best you can. 01:40:50.960 --> 01:40:52.950 I like the attitude. 01:40:56.520 --> 01:40:58.450 Hello, my name is Barbara [INAUDIBLE]. 01:40:58.450 --> 01:41:01.040 I was a teacher for 29 years before I got sick. 01:41:04.230 --> 01:41:05.525 I had to retire early. 01:41:05.525 --> 01:41:06.562 I miss the kids. 01:41:10.460 --> 01:41:11.680 I miss the nonsense. 01:41:11.680 --> 01:41:15.840 -What are your typical daily activities? 01:41:15.840 --> 01:41:17.520 -Some days Bingo. 01:41:17.520 --> 01:41:19.348 I never played Bingo before I came here. 01:41:23.710 --> 01:41:27.440 It's to socialize more. 01:41:27.440 --> 01:41:32.092 I struggle with the door since my room is so small. 01:41:32.092 --> 01:41:36.570 I'm in my own way with the chair, 01:41:36.570 --> 01:41:41.005 so to make it so it's easier without crashing into the door. 01:41:43.650 --> 01:41:46.680 The doors are very heavy for my left arm. 01:41:46.680 --> 01:41:54.630 Automatic doors in the room, would be very helpful. 01:41:54.630 --> 01:41:57.050 -What would be your perfect world interaction 01:41:57.050 --> 01:41:59.740 with the door? 01:41:59.740 --> 01:42:03.048 -I can open and close it without touching it. 01:42:06.436 --> 01:42:10.308 Some of the rooms already have the technology. 01:42:10.308 --> 01:42:11.276 Mine doesn't. 01:42:11.276 --> 01:42:13.570 -So it's easy to open it. 01:42:13.570 --> 01:42:18.905 But then once it's not moving, it's hard to do either. 01:42:18.905 --> 01:42:20.600 Also, like the door will not swing open, 01:42:20.600 --> 01:42:21.651 so you can't just push it because it 01:42:21.651 --> 01:42:22.567 doesn't let it happen. 01:42:22.567 --> 01:42:24.910 It locks itself. 01:42:24.910 --> 01:42:28.320 -Then we began our design process, 01:42:28.320 --> 01:42:30.570 which consisted of numerous measurements 01:42:30.570 --> 01:42:32.680 on everything related to Barbara's door. 01:42:36.360 --> 01:42:38.900 We then considered whether we wanted an app, button, 01:42:38.900 --> 01:42:43.570 or mechanical solution and started our ideation process. 01:42:43.570 --> 01:42:46.720 These ranged from an automatic collapsible door 01:42:46.720 --> 01:42:54.890 that opens with a pulley, to a mechanical lever 01:42:54.890 --> 01:43:02.390 that closes the door when you push on it, 01:43:02.390 --> 01:43:06.082 as well as a pulley system that opens and closes the door when 01:43:06.082 --> 01:43:07.275 you pull on the string. 01:43:11.980 --> 01:43:16.330 And lastly, we considered an automatic soundproof curtain 01:43:16.330 --> 01:43:21.930 system which would open with a touch of a button from pulleys. 01:43:21.930 --> 01:43:24.840 We decided to pursue the curtain idea, 01:43:24.840 --> 01:43:27.930 and are now beginning to prototype over and over 01:43:27.930 --> 01:43:32.030 and over again until we create the perfect automatic door. 01:43:39.680 --> 01:43:42.255 STUDENT 2: So that's just an overview of our design process. 01:43:42.255 --> 01:43:44.630 So I'm going to take you through the specifics of it now. 01:43:47.490 --> 01:43:50.542 So these are the three idea that we were pursuing for the door. 01:43:50.542 --> 01:43:52.000 And the first thing that we did was 01:43:52.000 --> 01:43:55.876 weigh the pros and cons of each possibility. 01:43:55.876 --> 01:43:57.500 So with the automatic collapsible door, 01:43:57.500 --> 01:43:59.680 we thought that this would serve as a good alternative 01:43:59.680 --> 01:44:01.200 because it's rigid, so it does still 01:44:01.200 --> 01:44:03.550 have the appearance of a door. 01:44:03.550 --> 01:44:05.340 But some issues we had with is that it 01:44:05.340 --> 01:44:08.260 was hard to find the parts to create a rigid collapsible 01:44:08.260 --> 01:44:13.220 door that was cheap and easy to put together. 01:44:13.220 --> 01:44:16.430 Next, we considered automatic curtains, which we thought 01:44:16.430 --> 01:44:19.430 would be very easy to implement and test, 01:44:19.430 --> 01:44:21.580 and we get soundproof curtains that could 01:44:21.580 --> 01:44:23.180 implement that part of it. 01:44:23.180 --> 01:44:26.510 But one issue is that it might not be door-like enough 01:44:26.510 --> 01:44:29.860 and fit in with like the norms of what doors simply look like, 01:44:29.860 --> 01:44:33.850 and the pulley system could get stuck as well. 01:44:33.850 --> 01:44:36.370 Lastly, we considered a mechanical lever and pulley 01:44:36.370 --> 01:44:40.180 system, so this would alter the door itself, 01:44:40.180 --> 01:44:42.990 so we wouldn't have any extra parts, 01:44:42.990 --> 01:44:45.920 and it should make the whole thing flow a little bit more 01:44:45.920 --> 01:44:46.420 smoothly. 01:44:46.420 --> 01:44:47.878 But it's kind of hard to implement, 01:44:47.878 --> 01:44:51.465 as we are not mechanical engineering students. 01:44:51.465 --> 01:44:53.340 So we decided to go with the middle approach, 01:44:53.340 --> 01:44:57.822 as it is very easy to test and prototype. 01:44:57.822 --> 01:44:59.780 But when we went to the Leonard Florence Center 01:44:59.780 --> 01:45:03.860 with our idea to see if there were any issues, 01:45:03.860 --> 01:45:05.760 we found that there were a lot. 01:45:05.760 --> 01:45:08.340 One of the first ones is that they consider curtains 01:45:08.340 --> 01:45:11.700 a major fire hazard because she could get stuck, 01:45:11.700 --> 01:45:15.650 or the curtains could get in the way of her leaving or entering 01:45:15.650 --> 01:45:16.210 her room. 01:45:18.820 --> 01:45:21.220 They also told is that this idea must be fail proof. 01:45:21.220 --> 01:45:24.600 So if there were a fire, the door must be able to close, 01:45:24.600 --> 01:45:27.529 and nothing should inhibit its way. 01:45:27.529 --> 01:45:29.320 So we tried to brainstorm another solution, 01:45:29.320 --> 01:45:31.840 and decided to go with our mechanical approach. 01:45:31.840 --> 01:45:34.440 But there we found that if we connected it 01:45:34.440 --> 01:45:41.210 with the fire alarm system, we could get our pulley 01:45:41.210 --> 01:45:45.035 to dislodge from the door if the fire alarm system goes off. 01:45:45.035 --> 01:45:46.410 And then this would hopefully not 01:45:46.410 --> 01:45:48.610 in impede with the door's mechanism 01:45:48.610 --> 01:45:50.860 when there is a fire alarm. 01:45:50.860 --> 01:45:55.160 But still they raised the problems of a fire hazard, that 01:45:55.160 --> 01:45:57.270 must be fail proof, and they also did not really 01:45:57.270 --> 01:46:00.910 understand how we would connect our new door system 01:46:00.910 --> 01:46:03.210 to the main system itself. 01:46:03.210 --> 01:46:06.030 And if we were to go through the peak system that is currently 01:46:06.030 --> 01:46:09.640 at the Leonard Florence Center, it's super expensive. 01:46:09.640 --> 01:46:14.680 And so we found it this idea is not very feasible for us. 01:46:14.680 --> 01:46:18.790 So this led us to work into her secondary problem, which 01:46:18.790 --> 01:46:20.100 is light automation. 01:46:20.100 --> 01:46:24.680 So the reason why this was her secondary preferences it's she, 01:46:24.680 --> 01:46:26.920 with third condition of PLS, she actually 01:46:26.920 --> 01:46:30.030 can't get up from her bed to shut off the light before she 01:46:30.030 --> 01:46:30.920 goes to bed. 01:46:30.920 --> 01:46:32.980 So she has to call a nurse to do so. 01:46:32.980 --> 01:46:35.900 So this impedes on her independence. 01:46:35.900 --> 01:46:37.350 This happens every day. 01:46:37.350 --> 01:46:39.510 So this would be a problem that if we could solve, 01:46:39.510 --> 01:46:42.570 it would help frequently, so she'd 01:46:42.570 --> 01:46:45.100 be able to have very good use of it. 01:46:45.100 --> 01:46:46.950 It's not like a one-case scenario. 01:46:46.950 --> 01:46:49.810 And this will also help her because in the future, when 01:46:49.810 --> 01:46:51.620 she is in a wheelchair, she may not 01:46:51.620 --> 01:46:53.890 be able to have the strength to reach up 01:46:53.890 --> 01:46:55.735 to the light to switch. 01:46:55.735 --> 01:46:59.810 Whereas with an application, she could, since PLS 01:46:59.810 --> 01:47:00.530 is progressive. 01:47:00.530 --> 01:47:04.100 So as a condition worsens this would be one of the this 01:47:04.100 --> 01:47:06.540 will be a possible solution that can like at least 01:47:06.540 --> 01:47:09.540 allow her to shut off the light when she wants to, 01:47:09.540 --> 01:47:13.040 and she's not in her bed for a longer period of time. 01:47:13.040 --> 01:47:23.170 So different processes we thought of doing this, 01:47:23.170 --> 01:47:24.820 we thought of using X10. 01:47:24.820 --> 01:47:28.150 So while we were searching, we found X10, 01:47:28.150 --> 01:47:33.380 so it's possible through Wi-Fi to send a signal to the X10 01:47:33.380 --> 01:47:34.580 transceiver. 01:47:34.580 --> 01:47:36.970 That sends a message to the outlet 01:47:36.970 --> 01:47:40.250 through electricity, some sort of like Morse code 01:47:40.250 --> 01:47:43.780 for electricity kind of, to give an idea of what it's doing. 01:47:43.780 --> 01:47:46.670 And then that can be used to turn on or off the light. 01:47:46.670 --> 01:47:50.020 So the process would be a little straight forward, 01:47:50.020 --> 01:47:52.230 since the products are available. 01:47:52.230 --> 01:47:54.270 It would just be us connecting them, 01:47:54.270 --> 01:47:57.880 and then the actual application already exists. 01:47:57.880 --> 01:48:00.960 And the price tag was about $100. 01:48:00.960 --> 01:48:03.330 Another idea we thought of was a more hands 01:48:03.330 --> 01:48:07.750 on approach of getting in Arduino to send a radio 01:48:07.750 --> 01:48:09.600 frequency signal to the light. 01:48:09.600 --> 01:48:14.440 We could buy the light that have as a receiver for this radio 01:48:14.440 --> 01:48:16.020 frequency signal. 01:48:16.020 --> 01:48:18.370 So then we would basically send a Bluetooth signal 01:48:18.370 --> 01:48:23.130 from her phone to the Arduino [? BLE ?] shield, 01:48:23.130 --> 01:48:25.750 and then that would send the signal 01:48:25.750 --> 01:48:27.650 to the corresponding light. 01:48:27.650 --> 01:48:29.820 So this was an option that we could also 01:48:29.820 --> 01:48:31.820 have that basically we just have to have 01:48:31.820 --> 01:48:36.910 multiple receivers, radio frequency receivers that 01:48:36.910 --> 01:48:38.600 are on the bottom right hand corner. 01:48:38.600 --> 01:48:40.330 So then she could send different signals 01:48:40.330 --> 01:48:43.790 from her phone to control each and every light independently. 01:48:43.790 --> 01:48:45.530 So it was an approach we thought of. 01:48:45.530 --> 01:48:48.094 The price tag on it was about $70 01:48:48.094 --> 01:48:50.510 because we would have to have the [? BLE ?] shield as well 01:48:50.510 --> 01:48:51.640 as the Arduino. 01:48:51.640 --> 01:48:54.150 And then the outlet, the receiver, 01:48:54.150 --> 01:48:55.490 was also a little bit of cash. 01:49:01.480 --> 01:49:04.720 So then after that we like started 01:49:04.720 --> 01:49:08.040 trying to come up with how we were going to do this. 01:49:08.040 --> 01:49:10.210 And our next idea was WeMo. 01:49:10.210 --> 01:49:11.520 We saw this online. 01:49:11.520 --> 01:49:14.280 Basically, they have their own solution for it. 01:49:14.280 --> 01:49:17.377 Basically, you can connect to it through an application 01:49:17.377 --> 01:49:18.710 that they already have provided. 01:49:18.710 --> 01:49:22.080 The application is free, and the product actually costs $41. 01:49:22.080 --> 01:49:26.740 So we thought of having this implemented in her system 01:49:26.740 --> 01:49:30.200 and then possibly expanding the SDK for the application 01:49:30.200 --> 01:49:34.270 so that she could have an easier time using it, 01:49:34.270 --> 01:49:36.117 and then have it basically tailored to her 01:49:36.117 --> 01:49:38.075 so that she only had to look at the application 01:49:38.075 --> 01:49:43.465 and touch larger buttons since the buttons are 01:49:43.465 --> 01:49:46.560 a little smaller than we would hope. 01:49:46.560 --> 01:49:48.450 Possible next steps is what I just 01:49:48.450 --> 01:49:51.490 said, where we expand an application based 01:49:51.490 --> 01:49:55.730 off the SDK for WeMo and make that app available for her. 01:49:55.730 --> 01:49:59.850 Or if this ends up being a solution right of the shell, 01:49:59.850 --> 01:50:02.730 then we could possibly taken an avenue where 01:50:02.730 --> 01:50:05.730 after fixing this light problem with WeMo, 01:50:05.730 --> 01:50:08.770 go into the voice applications so try and see 01:50:08.770 --> 01:50:10.670 if we can tailor voice application for her. 01:50:15.050 --> 01:50:17.150 So our timeline is by the end of October, 01:50:17.150 --> 01:50:19.045 we hope to have WeMo installed. 01:50:19.045 --> 01:50:21.230 The first half of November we hope 01:50:21.230 --> 01:50:25.940 to prototype the like UI for either the voice app, 01:50:25.940 --> 01:50:29.110 also, possibly, if necessary, the light app. 01:50:29.110 --> 01:50:32.690 Second half, we would like to have this app done in iOS. 01:50:32.690 --> 01:50:35.370 The reason for prototyping [INAUDIBLE] it's faster, 01:50:35.370 --> 01:50:37.625 and we can get a lot of the UI feel really quickly. 01:50:37.625 --> 01:50:39.000 And then after that we would just 01:50:39.000 --> 01:50:40.920 keep testing and iterating until we have a product that 01:50:40.920 --> 01:50:41.920 fits Barbara's needs. 01:50:47.597 --> 01:50:48.180 Any questions? 01:50:53.330 --> 01:50:55.080 PROFESSOR 1: Could you say a bit about how 01:50:55.080 --> 01:50:57.371 you're going to divide the work among the three of you? 01:50:57.371 --> 01:51:02.190 STUDENT 3: OK, so in terms of the work for the door, 01:51:02.190 --> 01:51:04.050 we've been all going to the center 01:51:04.050 --> 01:51:05.850 to speak with as many people as possible. 01:51:05.850 --> 01:51:07.760 So for the time being, it's been a lot 01:51:07.760 --> 01:51:11.360 of contextual inquiry and a lot like designing all together. 01:51:11.360 --> 01:51:16.800 But in terms of the next steps for installing the WeMo, 01:51:16.800 --> 01:51:18.780 we were going to go to the center together 01:51:18.780 --> 01:51:21.840 and while two of the members were 01:51:21.840 --> 01:51:24.260 going to be working on installing this in the room, 01:51:24.260 --> 01:51:26.570 we were also going to continue to ask about the door, 01:51:26.570 --> 01:51:28.589 we are pushing towards like at least speaking 01:51:28.589 --> 01:51:30.630 to a lot of members in the center about the door, 01:51:30.630 --> 01:51:32.338 since that is an issue that we would hope 01:51:32.338 --> 01:51:34.330 would be solved in the future. 01:51:34.330 --> 01:51:37.110 After that is installed, the dividing the actual application 01:51:37.110 --> 01:51:42.200 process, so since we, as a team, don't all 01:51:42.200 --> 01:51:44.840 have like skills in App Inventor and iOS, 01:51:44.840 --> 01:51:46.960 we were going to divide up so that we would end up 01:51:46.960 --> 01:51:49.610 having some of the base code that would definitely 01:51:49.610 --> 01:51:51.870 be necessary for iOS built right from the beginning 01:51:51.870 --> 01:51:54.460 while the UI is being prototyping in App Inventor. 01:51:54.460 --> 01:51:56.740 So in terms of like team specific, 01:51:56.740 --> 01:52:00.080 it would be two members working on the iOS application, 01:52:00.080 --> 01:52:02.650 while one member just continually prototypes 01:52:02.650 --> 01:52:05.170 the ideas that the team comes up with in App Inventory 01:52:05.170 --> 01:52:07.210 to like give a feel for it. 01:52:07.210 --> 01:52:11.100 We would always go as a team to show this to Barbara. 01:52:11.100 --> 01:52:14.840 And then once the App Inventor UI decision is made, 01:52:14.840 --> 01:52:16.730 we would all be working on the iOS apps 01:52:16.730 --> 01:52:18.813 since that's going to be the majority of the part. 01:52:21.850 --> 01:52:24.567 Any other questions? 01:52:24.567 --> 01:52:26.025 PROFESSOR 5: So basically, the door 01:52:26.025 --> 01:52:27.592 is sort of too hard is basically-- 01:52:27.592 --> 01:52:28.550 it's just not workable? 01:52:29.714 --> 01:52:31.880 STUDENT 2: There a lot of regulations with the door. 01:52:31.880 --> 01:52:33.546 We'd have to get it approved by the fire 01:52:33.546 --> 01:52:35.880 department, the public health department, and the people 01:52:35.880 --> 01:52:37.504 at the center, a lot of them don't even 01:52:37.504 --> 01:52:39.680 know how it functions and how it connects up 01:52:39.680 --> 01:52:43.110 to like the central system that closes all the doors when 01:52:43.110 --> 01:52:44.570 a fire alarm goes off. 01:52:44.570 --> 01:52:46.695 So it would require a lot more research, 01:52:46.695 --> 01:52:48.570 and we're not sure if it's feasible to finish 01:52:48.570 --> 01:52:51.560 this project in the next two or three months that we have. 01:52:59.501 --> 01:53:01.000 JESSICA HERRING: So we are Team Art. 01:53:01.000 --> 01:53:01.500 I'm Jessica. 01:53:02.055 --> 01:53:03.013 RACHEL ELLISON: Rachel. 01:53:04.009 --> 01:53:05.300 STEPHANIE CHEN : I'm Stephanie. 01:53:05.300 --> 01:53:07.383 JESSICA HERRING: And what we have decided to build 01:53:07.383 --> 01:53:09.340 is a power lift. 01:53:09.340 --> 01:53:11.260 So first, we're going to introduce our client. 01:53:11.260 --> 01:53:12.810 His name is Art. 01:53:12.810 --> 01:53:15.670 He is an adaptive rock climber, a hacker, a tinkerer. 01:53:15.670 --> 01:53:19.400 He likes to build stuff-- adapt stuff 01:53:19.400 --> 01:53:22.150 to his specifications and his desires, 01:53:22.150 --> 01:53:24.950 and he's a very active member of his community. 01:53:24.950 --> 01:53:28.470 He has a girlfriend, and she works in his hacker space 01:53:28.470 --> 01:53:30.440 at the Artisans Asylum in Somerville, 01:53:30.440 --> 01:53:33.660 which is pretty much a hacker space, where 01:53:33.660 --> 01:53:35.850 people build stuff. 01:53:35.850 --> 01:53:39.430 However, he has T5 Asia B Paraplegia, which 01:53:39.430 --> 01:53:41.990 is an incomplete paraplegic. 01:53:41.990 --> 01:53:45.730 So he has some sensory function below his waist, 01:53:45.730 --> 01:53:47.910 but no motor function. 01:53:47.910 --> 01:53:51.480 In addition to this, he has a grade 2 shoulder separation 01:53:51.480 --> 01:53:54.209 that is not quite bad enough to need surgery, 01:53:54.209 --> 01:53:56.500 but we do want to consider this when making our design. 01:53:56.500 --> 01:54:01.450 We don't want to make our mechanisms too manual. 01:54:01.450 --> 01:54:04.190 So Art wants to be able to work on the floor. 01:54:04.190 --> 01:54:08.250 He wants to be able to get under some of his bigger projects, 01:54:08.250 --> 01:54:11.379 like he'll lift up a wheelchair on his lift that he's designed, 01:54:11.379 --> 01:54:12.670 and he'll want to get under it. 01:54:12.670 --> 01:54:13.910 But it's really hard to do that when 01:54:13.910 --> 01:54:15.326 you're getting out of a wheelchair 01:54:15.326 --> 01:54:16.880 and you can't move your legs. 01:54:16.880 --> 01:54:20.120 So, in addition to that, if you were to fall out of his chair, 01:54:20.120 --> 01:54:22.706 he would like to be able to use something to get back up 01:54:22.706 --> 01:54:23.702 alone independently. 01:54:23.702 --> 01:54:27.686 [VIDEO PLAYBACK] 01:54:47.606 --> 01:54:52.088 -Well, I'm a [INAUDIBLE] minded person, a lot of independence. 01:54:52.088 --> 01:54:59.060 Before I got hurt in March of 2010, 01:54:59.060 --> 01:55:02.046 I was the person who took care of all of our household 01:55:02.046 --> 01:55:02.546 maintenance. 01:55:02.546 --> 01:55:05.534 I did a lot of motorcycle repair. 01:55:05.534 --> 01:55:08.024 [INAUDIBLE] 01:55:08.024 --> 01:55:12.506 Pretty much [INAUDIBLE], I worked on it. 01:55:12.506 --> 01:55:15.010 Now, I still try to do as much of that as I can. 01:55:15.010 --> 01:55:18.344 We're filming this at Artisan's Asylum, which 01:55:18.344 --> 01:55:21.180 is one of the world's largest hacker spaces, 01:55:21.180 --> 01:55:23.319 maker spaces and collaborative workshops 01:55:23.319 --> 01:55:26.630 that anyone [INAUDIBLE]. 01:55:26.630 --> 01:55:32.889 We have shops that cover an incredibly wide range of skills 01:55:32.889 --> 01:55:33.847 and technology. 01:55:38.650 --> 01:55:42.090 What they call a T-5 Asia B, which basically means that 01:55:42.090 --> 01:55:46.887 from about here down I have no motor function. 01:55:46.887 --> 01:55:48.970 Because I can't get in and out of my chair easily, 01:55:48.970 --> 01:55:51.742 I'm more or less limited to doing things 01:55:51.742 --> 01:55:52.866 that I can sit in front of. 01:56:33.702 --> 01:56:44.658 [END PLAYBACK] 01:56:44.658 --> 01:56:47.148 JESSICA HERRING: He is quite a character, 01:56:47.148 --> 01:56:51.230 and he's very specific about he wants. 01:56:51.230 --> 01:56:54.170 But we figure that we can help him out with that. 01:56:54.170 --> 01:56:56.536 So our goal is to design something that's portable, 01:56:56.536 --> 01:56:58.240 something that's lightweight, something 01:56:58.240 --> 01:57:00.870 that is about the height of his chair 01:57:00.870 --> 01:57:04.600 that he can get in and out of and get up and down with. 01:57:04.600 --> 01:57:07.860 So the height of the wheelchair seat-- Art cat 01:57:07.860 --> 01:57:12.230 only move about three or four inches vertically by himself. 01:57:12.230 --> 01:57:14.690 And so we need our device to be about the height 01:57:14.690 --> 01:57:17.400 of his wheelchair seat, which is 22 inches tall, 01:57:17.400 --> 01:57:20.420 but we'd also like it to be used anywhere he wants to use it. 01:57:20.420 --> 01:57:23.520 So we originally wanted him to be able to take it with him, 01:57:23.520 --> 01:57:25.970 and that's still one of our goals. 01:57:25.970 --> 01:57:28.300 We also need it to weigh under 20 pounds. 01:57:28.300 --> 01:57:29.990 This is because he wants his girlfriend 01:57:29.990 --> 01:57:32.365 to be able to take it to him if he falls out of his chair 01:57:32.365 --> 01:57:34.430 and needs it or for some other reason. 01:57:34.430 --> 01:57:36.150 His girlfriend can only lift 20 pounds 01:57:36.150 --> 01:57:39.700 because she has a medical condition that restricts that. 01:57:39.700 --> 01:57:43.170 So our major success metric is time. 01:57:43.170 --> 01:57:44.600 A lot of these design constraints 01:57:44.600 --> 01:57:48.310 will make or break the project, but the time is a variable. 01:57:48.310 --> 01:57:51.510 So we would like it to be approximately one minute. 01:57:51.510 --> 01:57:53.780 Art wanted something a little more like 30 seconds 01:57:53.780 --> 01:57:56.161 to 45 seconds, but we think a minute would also be OK. 01:58:00.640 --> 01:58:03.580 STEPHANIE CHEN : So after taking these design limitations 01:58:03.580 --> 01:58:06.510 into account, we decided to look into products that were 01:58:06.510 --> 01:58:08.030 commercially available. 01:58:08.030 --> 01:58:18.340 So at first, we began looking into commercially available 01:58:18.340 --> 01:58:19.360 medical technology. 01:58:19.360 --> 01:58:21.350 For example, that up there is something called 01:58:21.350 --> 01:58:23.020 an [? elk ?] emergency lift. 01:58:23.020 --> 01:58:27.510 It's probably the most ideal out of these products 01:58:27.510 --> 01:58:30.770 for our client because it weighs approximately five pounds 01:58:30.770 --> 01:58:33.330 and it can support 1,000 pounds. 01:58:33.330 --> 01:58:37.820 The only problem with it is that it costs $3,000 at least, 01:58:37.820 --> 01:58:42.190 and there's no guaranteed stability if he's actually 01:58:42.190 --> 01:58:43.130 lifting in the chair. 01:58:43.130 --> 01:58:46.380 There's nothing preventing them from falling to the side. 01:58:46.380 --> 01:58:48.320 And just for fun, we decided to look 01:58:48.320 --> 01:58:50.886 into other types of lifting cushions 01:58:50.886 --> 01:58:52.380 available in other industries. 01:58:52.380 --> 01:58:54.980 We actually found something called the Map Jack, which 01:58:54.980 --> 01:58:56.160 is something similar. 01:58:56.160 --> 01:59:01.680 It costs about $800, and it can lift probably six tons-- 01:59:01.680 --> 01:59:03.330 fun fact. 01:59:03.330 --> 01:59:07.090 We then decided to look into the idea of a scissor lift, which 01:59:07.090 --> 01:59:11.415 is a relatively prevalent lifting mechanism. 01:59:11.415 --> 01:59:15.240 You can find it in construction sites and warehouses and so on. 01:59:15.240 --> 01:59:18.450 The problem with that idea is that there 01:59:18.450 --> 01:59:22.670 is a lot of friction losses associated with scissor lifts, 01:59:22.670 --> 01:59:25.471 and considering the fact that none of us 01:59:25.471 --> 01:59:27.729 are mechanical engineers, we decided 01:59:27.729 --> 01:59:29.770 it would be best if we started off with something 01:59:29.770 --> 01:59:30.580 a little simpler. 01:59:30.580 --> 01:59:34.170 And actually, if we consider the weight of a scissor lift 01:59:34.170 --> 01:59:39.890 into account, it would certainly weigh more than 20 pounds. 01:59:39.890 --> 01:59:44.470 We then decided to look into a pool lift, which Art actually 01:59:44.470 --> 01:59:45.110 owns. 01:59:45.110 --> 01:59:49.160 The main issue with this idea is that unfortunately it's 01:59:49.160 --> 01:59:55.060 stationary, and we require a very powerful linear actuator, 01:59:55.060 --> 01:59:56.780 so we decided to scrap those ideas. 01:59:59.840 --> 02:00:02.070 One idea that we actually came across 02:00:02.070 --> 02:00:06.020 is something similar to one of those stair lifts. 02:00:06.020 --> 02:00:07.720 It's essentially a sliding lift. 02:00:07.720 --> 02:00:10.440 It'll bring someone who's not capable of going to upstairs 02:00:10.440 --> 02:00:14.390 from the bottom to the top of their staircase. 02:00:14.390 --> 02:00:17.400 And Art was actually in preference of this idea. 02:00:17.400 --> 02:00:22.960 As you can see, based on the lower sketch, 02:00:22.960 --> 02:00:24.890 it appears to be relatively light design. 02:00:24.890 --> 02:00:28.210 And it's incredibly portable because it essentially 02:00:28.210 --> 02:00:30.450 looked like a tripod. 02:00:30.450 --> 02:00:34.480 And unfortunately, the major disadvantages of this 02:00:34.480 --> 02:00:40.200 is we, again, have to deal with a lot of friction losses, 02:00:40.200 --> 02:00:41.920 and we also have to include a bunch 02:00:41.920 --> 02:00:44.140 of fail safes such as hand brakes, 02:00:44.140 --> 02:00:48.630 just to ensure that he doesn't accidentally slide down when 02:00:48.630 --> 02:00:52.921 he's near the top of the ramp. 02:00:52.921 --> 02:00:54.420 And for this design we actually need 02:00:54.420 --> 02:00:57.180 a very specialized motor, something that's low speed 02:00:57.180 --> 02:00:59.790 and high in torque. 02:00:59.790 --> 02:01:06.300 One idea that-- so this is actually our 02:01:06.300 --> 02:01:08.280 currently most worked done idea. 02:01:08.280 --> 02:01:10.550 It's a screw lift essentially. 02:01:10.550 --> 02:01:15.550 And that is a smaller scale prototype. 02:01:15.550 --> 02:01:19.070 Based on this drawing, you can see that we essentially 02:01:19.070 --> 02:01:23.390 take multiple 80-20 rods and arrange them 02:01:23.390 --> 02:01:26.310 in that sort of fashion, so you have one rod on this side 02:01:26.310 --> 02:01:30.210 and one rod on the other, where there's a seat in the middle. 02:01:30.210 --> 02:01:32.990 And in between those two rods, and what's holding up 02:01:32.990 --> 02:01:34.770 the chair, is a threaded rod. 02:01:34.770 --> 02:01:37.650 So essentially we'd be using either 02:01:37.650 --> 02:01:41.220 a drill motor or any sort of motor 02:01:41.220 --> 02:01:45.880 to twist that threaded rod to lift or to cause 02:01:45.880 --> 02:01:48.290 the chair to ascend or descend. 02:01:48.290 --> 02:01:49.780 The major advantage to this is it 02:01:49.780 --> 02:01:52.977 can be designed to be rather foldable, 02:01:52.977 --> 02:01:54.810 and we don't have to build in any fail safes 02:01:54.810 --> 02:01:57.440 because we're dealing with a threaded rod. 02:01:57.440 --> 02:02:01.500 And actually, the motors required for this design 02:02:01.500 --> 02:02:03.600 are also relatively cheaper. 02:02:03.600 --> 02:02:06.490 But the major disadvantages to this idea, 02:02:06.490 --> 02:02:10.360 in particular, is that we have to work with multiple parts, 02:02:10.360 --> 02:02:14.190 and this could be a potentially heavy idea. 02:02:17.690 --> 02:02:21.350 So here is actually a video of the prototype. 02:02:53.105 --> 02:02:54.980 RACHEL ELLISON: So this showing it does move. 02:02:54.980 --> 02:02:56.105 This me turning it by hand. 02:02:56.105 --> 02:03:01.100 And so if you're turning it at maybe 100, 150, 02:03:01.100 --> 02:03:03.520 it would be moving a lot faster. 02:03:03.520 --> 02:03:08.260 The [INAUDIBLE] we're looking at are eight turns per inch. 02:03:08.260 --> 02:03:13.102 So at 22 inches, we are looking at about 200 turns. 02:03:19.060 --> 02:03:21.480 So the next steps in our process really 02:03:21.480 --> 02:03:24.780 are to expand on these two ideas and decide 02:03:24.780 --> 02:03:28.110 which design to pursue. 02:03:28.110 --> 02:03:30.090 Stephanie is handing around now 80-20 02:03:30.090 --> 02:03:33.420 rod, which is the basis of our sliding mechanism. 02:03:33.420 --> 02:03:35.350 And really what we're trying to do 02:03:35.350 --> 02:03:36.970 is understand what parts we'll be 02:03:36.970 --> 02:03:39.980 able to get within our budget constraints 02:03:39.980 --> 02:03:43.180 and which one will provide a lighter weight 02:03:43.180 --> 02:03:45.980 design that fits more of our design specifications. 02:03:45.980 --> 02:03:48.610 We'd like it to be full scale, our next prototype, 02:03:48.610 --> 02:03:52.780 and we're going to prioritize durability and sturdiness. 02:03:52.780 --> 02:03:56.760 After that, we'd like to make a more polished prototype 02:03:56.760 --> 02:03:58.250 of our final idea. 02:03:58.250 --> 02:04:00.780 We'd like this one to fold up to be transportable 02:04:00.780 --> 02:04:02.744 and to be within our weight specifications. 02:04:02.744 --> 02:04:04.160 For our first prototype, we're not 02:04:04.160 --> 02:04:06.564 going to worry so much about that. 02:04:06.564 --> 02:04:08.230 We'd like to try to optimize the lifting 02:04:08.230 --> 02:04:10.430 time and the speed at which the motor turns 02:04:10.430 --> 02:04:12.012 to lift Art up and down. 02:04:12.012 --> 02:04:14.220 And finally, we'd like to think about the feasibility 02:04:14.220 --> 02:04:16.000 of mass production of this device 02:04:16.000 --> 02:04:18.440 and what is going into it and whether those things will 02:04:18.440 --> 02:04:21.460 be available for other users. 02:04:21.460 --> 02:04:24.851 And so our projected costs with the slider design 02:04:24.851 --> 02:04:26.600 which is a little bit more expensive we're 02:04:26.600 --> 02:04:29.380 going to need a linear bearing to slide up and down the broad 02:04:29.380 --> 02:04:32.040 with hand brake built in so that it will be 02:04:32.040 --> 02:04:34.000 stable at the top of the ramp. 02:04:34.000 --> 02:04:36.060 And that's about $65. 02:04:36.060 --> 02:04:38.030 For a high torque, low speed motor, 02:04:38.030 --> 02:04:41.870 those are pretty pricey and come at $60 to $80 new. 02:04:41.870 --> 02:04:44.320 We've been looking into scavenging this part 02:04:44.320 --> 02:04:46.590 to try to cut down costs. 02:04:46.590 --> 02:04:49.020 We'll also need other parts, such as hinges and legs, 02:04:49.020 --> 02:04:51.190 so that'll fold up. 02:04:51.190 --> 02:04:53.840 For the screw lift design, we're looking 02:04:53.840 --> 02:04:59.230 at using a threaded rod, and this Acme thread design 02:04:59.230 --> 02:05:01.590 is a special kind of threading designed to bear weight 02:05:01.590 --> 02:05:05.330 and not snag so that we can turn it hopefully at higher speeds. 02:05:05.330 --> 02:05:07.520 We'll also need a low torque, higher speed motor. 02:05:07.520 --> 02:05:09.019 Those will be significantly cheaper, 02:05:09.019 --> 02:05:12.266 and actually we have several of those on hand right now. 02:05:12.266 --> 02:05:13.640 And the rest of the lift is going 02:05:13.640 --> 02:05:16.060 to be aluminum or wooden parts which can 02:05:16.060 --> 02:05:18.480 come from the hardware store. 02:05:18.480 --> 02:05:21.260 So with that, I'd like to thank teammates Jessica, who's 02:05:21.260 --> 02:05:23.850 been in charge of videotaping our meetings 02:05:23.850 --> 02:05:27.340 and edited both the lovely videos you saw earlier, 02:05:27.340 --> 02:05:29.580 Stephanie, who's been heading up our prototyping 02:05:29.580 --> 02:05:33.120 and is going to be doing a lot of stuff 02:05:33.120 --> 02:05:34.696 with building in the next few weeks, 02:05:34.696 --> 02:05:36.320 and then I'm not going to thank myself, 02:05:36.320 --> 02:05:38.920 but I've been doing a lot of the interviewing and client 02:05:38.920 --> 02:05:40.760 communication. 02:05:40.760 --> 02:05:43.147 We'd also like to give a special thanks to Don Fredette 02:05:43.147 --> 02:05:44.730 at The Boston House, who's provided us 02:05:44.730 --> 02:05:48.180 with a lot of guidance, parts, moral support, Joseph 02:05:48.180 --> 02:05:50.360 Parse, in the Department of Material Science 02:05:50.360 --> 02:05:52.860 and Engineering, who helped us figure out the screw lift 02:05:52.860 --> 02:05:55.790 design and what parts we'd need to make it work, 02:05:55.790 --> 02:05:58.200 and finally our client himself has helped us 02:05:58.200 --> 02:06:01.610 a lot with the design feasibility and sourcing parts, 02:06:01.610 --> 02:06:04.110 and since he works at this hacker space, 02:06:04.110 --> 02:06:06.250 he's also volunteered to help us put it together, 02:06:06.250 --> 02:06:08.625 and, of course, the PPAT staff makes this class possible. 02:06:10.892 --> 02:06:11.475 Any questions? 02:06:15.343 --> 02:06:17.634 PROFESSOR 4: We have about three minutes for questions. 02:06:20.198 --> 02:06:22.406 PROFESSOR 4: Have you looked at Kiva Systems, a robot 02:06:22.406 --> 02:06:23.455 for warehouse automation? 02:06:23.455 --> 02:06:25.867 They were bought for $600 million 02:06:25.867 --> 02:06:27.620 by Amazon a couple years ago. 02:06:27.620 --> 02:06:30.080 But they have a lift, a clever lift mechanism. 02:06:30.080 --> 02:06:33.897 Their founder talked to [? Mickey ?] last week. 02:06:33.897 --> 02:06:35.480 Maybe I can give you a pointer or two. 02:06:35.480 --> 02:06:36.710 They have a clever design. 02:06:36.710 --> 02:06:37.543 Maybe it's the same. 02:06:41.020 --> 02:06:43.975 But I do worry about the overall electromechanical robustness. 02:06:46.980 --> 02:06:50.200 Have you thought about how the whole-- the power, 02:06:50.200 --> 02:06:54.587 the connectors, the control everything puts together? 02:06:54.587 --> 02:06:56.920 RACHEL ELLISON: We should have said something about this 02:06:56.920 --> 02:06:59.350 during the presentation, but Art has 02:06:59.350 --> 02:07:03.870 hacked into 24 volt battery system in his chair 02:07:03.870 --> 02:07:05.910 and has an Anderson volt connector that we 02:07:05.910 --> 02:07:07.325 can use to power our devices. 02:07:07.325 --> 02:07:10.917 PROFESSOR 4: So you'll connect in to the wheelchair battery. 02:07:10.917 --> 02:07:13.250 PROFESSOR 6: So that partly answered one of my question. 02:07:13.250 --> 02:07:13.750 I had two. 02:07:13.750 --> 02:07:18.480 One, what equipment does Art use at makers space, and two, 02:07:18.480 --> 02:07:22.330 has he adapted or hacked any of his existing? 02:07:22.330 --> 02:07:24.213 So yes, he has hacked his wheelchair. 02:07:24.213 --> 02:07:26.546 JESSICA HERRING: He does that quite frequently actually. 02:07:26.546 --> 02:07:28.157 He replaces his joystick. 02:07:28.157 --> 02:07:35.552 He [INAUDIBLE] adjust the sensitivity for [INAUDIBLE]. 02:07:35.552 --> 02:07:39.706 RACHEL ELLISON: I think he uses the [INAUDIBLE], 02:07:39.706 --> 02:07:42.289 and he's built this foot peddle to help him use variable speed 02:07:42.289 --> 02:07:42.947 devices. 02:07:42.947 --> 02:07:45.732 He can't use his feet. 02:07:45.732 --> 02:07:47.190 I'm not sure realistically how much 02:07:47.190 --> 02:07:49.410 he's going to be able to help us with putting it together. 02:07:49.410 --> 02:07:51.493 But we thought it was really kind that he offered, 02:07:51.493 --> 02:07:54.035 and maybe there will be things that he's able to assist with. 02:07:54.035 --> 02:07:55.409 PROFESSOR 6: [INAUDIBLE] it could 02:07:55.409 --> 02:07:57.860 be interesting to think about then going forward, even 02:07:57.860 --> 02:07:59.890 beyond the class, how do you design this 02:07:59.890 --> 02:08:02.590 so that he can continue tinkering 02:08:02.590 --> 02:08:04.510 with it after the semester is done, 02:08:04.510 --> 02:08:06.129 if he's already in a position and is 02:08:06.129 --> 02:08:07.170 interested in doing that. 02:08:07.170 --> 02:08:07.711 That's great. 02:08:10.280 --> 02:08:12.280 PROFESSOR 1: So this is interesting in the sense 02:08:12.280 --> 02:08:14.260 that he's intentionally on the ground, right? 02:08:14.260 --> 02:08:17.670 You're not trying to recover from fall, 02:08:17.670 --> 02:08:21.600 which I think is where many of the other assistive devices 02:08:21.600 --> 02:08:24.460 are thinking about. 02:08:24.460 --> 02:08:27.400 I want to actually probe on this one minute time 02:08:27.400 --> 02:08:30.600 because if he's intentionally getting on the ground, 02:08:30.600 --> 02:08:36.240 he's maybe planning to get back up, 02:08:36.240 --> 02:08:38.890 and he might do it, in fact, frequently-- getting under, 02:08:38.890 --> 02:08:41.370 getting back in the chair to go somewhere else for a tool, 02:08:41.370 --> 02:08:44.570 then going back and getting under again. 02:08:44.570 --> 02:08:47.370 Does the one minute that you're talking about, is that just 02:08:47.370 --> 02:08:50.520 measuring the time that it takes like the motor 02:08:50.520 --> 02:08:53.030 to propel him up to wheelchair height, 02:08:53.030 --> 02:08:57.523 or are we talking about the time to set it all up, get on it, 02:08:57.523 --> 02:09:00.036 as well as move up? 02:09:00.036 --> 02:09:04.244 STEPHANIE CHEN : That's the time he wants to spend actually 02:09:04.244 --> 02:09:06.160 maneuvering himself on the floor to his chair. 02:09:06.160 --> 02:09:10.940 So we haven't actually taken into consideration setup time, 02:09:10.940 --> 02:09:14.160 though I guess that's another thing we can add in. 02:09:14.160 --> 02:09:16.510 But, again, that's going to depend on the design 02:09:16.510 --> 02:09:18.116 we choose, but some may be, I guess, 02:09:18.116 --> 02:09:21.497 modular in the sense that it may take some [INAUDIBLE] 02:09:21.497 --> 02:09:25.828 apart and actually have to assemble the entire apparatus. 02:09:25.828 --> 02:09:28.574 But for now, we're just focusing on the time length 02:09:28.574 --> 02:09:29.990 between him getting from the floor 02:09:29.990 --> 02:09:32.320 to the chair or vice versa. 02:09:32.320 --> 02:09:34.160 RACHEL ELLISON: So another reason to favor 02:09:34.160 --> 02:09:36.320 this screw lift over the slider lift 02:09:36.320 --> 02:09:39.520 is that that's a lot more flexibility in how fast 02:09:39.520 --> 02:09:41.200 the thing goes up and down. 02:09:41.200 --> 02:09:42.950 With a slider lift, because so much torque 02:09:42.950 --> 02:09:46.890 is required to just move a pulley that way, 02:09:46.890 --> 02:09:51.250 we'd be looking at-- we have a minimum possible time of about 02:09:51.250 --> 02:09:52.115 45 seconds. 02:09:52.115 --> 02:09:54.240 Whereas with the screw lift, pretty much the faster 02:09:54.240 --> 02:09:56.390 you turn the motor, the faster the thing moves. 02:09:56.390 --> 02:09:58.180 And then the only top consideration 02:09:58.180 --> 02:10:00.840 really is how fast we can move it safely. 02:10:00.840 --> 02:10:02.256 We certainly don't want to put him 02:10:02.256 --> 02:10:04.570 in risk of being propelled off the chair 02:10:04.570 --> 02:10:07.990 or dumped onto the floor. 02:10:07.990 --> 02:10:09.705 PROFESSOR 1: I'd encourage you to include 02:10:09.705 --> 02:10:13.165 setup time as one of your metrics for at least 02:10:13.165 --> 02:10:13.665 [INAUDIBLE]. 02:10:18.069 --> 02:10:20.110 PROFESSOR 4: OK, any final questions or comments? 02:10:20.110 --> 02:10:23.190 All right, thank you, Team Art. 02:10:23.190 --> 02:10:24.677 And we'll jump right in. 02:10:24.677 --> 02:10:25.177 Thank you. 02:10:35.157 --> 02:10:36.150 Hi, everyone. 02:10:36.150 --> 02:10:38.690 We're team Chris. 02:10:38.690 --> 02:10:40.610 So I'll introduce ourselves. 02:10:40.610 --> 02:10:41.570 This is Arthie. 02:10:41.570 --> 02:10:43.460 She's a senior, and she is our point 02:10:43.460 --> 02:10:45.940 of contact for the semester with our client, who 02:10:45.940 --> 02:10:47.690 we'll introduce later. 02:10:47.690 --> 02:10:49.420 Next is Carolyn right over there. 02:10:49.420 --> 02:10:52.640 She is also a senior, and she is the person 02:10:52.640 --> 02:10:55.010 in charge of keeping us on task during our meetings, 02:10:55.010 --> 02:10:58.240 make sure focused, and make sure that we're following our goals 02:10:58.240 --> 02:11:01.040 and aiming for goals every meeting. 02:11:01.040 --> 02:11:03.320 PHOEBE: Next, we have Dirk, who's a junior, 02:11:03.320 --> 02:11:06.180 and he is our main scribe for the semester. 02:11:06.180 --> 02:11:07.680 And then there's me, Phoebe. 02:11:07.680 --> 02:11:11.750 I'm the main photographer and videographer for this semester. 02:11:11.750 --> 02:11:14.460 And, of course, our most important member of the team 02:11:14.460 --> 02:11:15.610 is Chris. 02:11:15.610 --> 02:11:18.790 He is a first year MBA student at Boston College. 02:11:18.790 --> 02:11:22.790 He loves to read, blog, and he loves baseball. 02:11:22.790 --> 02:11:25.340 So he has this rare condition called 02:11:25.340 --> 02:11:29.570 Miyoshi Myopathy, which is a progressive muscular dystrophy 02:11:29.570 --> 02:11:30.360 condition. 02:11:30.360 --> 02:11:32.917 So he can only walk short distances 02:11:32.917 --> 02:11:34.667 and can only carry a small load at a time. 02:11:41.274 --> 02:11:42.690 STUDENT 4: The activity that Chris 02:11:42.690 --> 02:11:44.340 would like us to help him with is just 02:11:44.340 --> 02:11:46.750 as daily movements throughout the world. 02:11:46.750 --> 02:11:49.540 Since he uses forearm crutches and a scooter, 02:11:49.540 --> 02:11:53.040 he needs place that don't have stairs and elevators to get 02:11:53.040 --> 02:11:55.070 around. 02:11:55.070 --> 02:11:56.860 Currently, when he wants to go anywhere, 02:11:56.860 --> 02:11:58.730 he has to research that place online. 02:11:58.730 --> 02:12:01.550 He uses Google Maps, and he uses Yelp. 02:12:01.550 --> 02:12:03.430 Yelp has a little bit of information. 02:12:03.430 --> 02:12:08.870 But really what he uses is the Google Maps Street View feature 02:12:08.870 --> 02:12:11.080 because he can actually see where he can get up 02:12:11.080 --> 02:12:13.530 onto a sidewalk or the front door, 02:12:13.530 --> 02:12:16.960 if there's stairs up to the door and things like that. 02:12:16.960 --> 02:12:18.480 If he can't get enough information 02:12:18.480 --> 02:12:20.360 from online resources, sometimes he 02:12:20.360 --> 02:12:22.630 can call the building, the restaurant, whatever 02:12:22.630 --> 02:12:24.390 he wants to do, and they can give him 02:12:24.390 --> 02:12:26.130 some more information that way. 02:12:26.130 --> 02:12:29.280 On campus, he primarily uses the disabilities office, 02:12:29.280 --> 02:12:31.010 and oftentimes he has to go in and talk 02:12:31.010 --> 02:12:33.200 to them because there's not very much information 02:12:33.200 --> 02:12:34.450 on their website. 02:12:34.450 --> 02:12:36.280 And can you go back? 02:12:36.280 --> 02:12:39.000 One thing that's really hard about some of these things, 02:12:39.000 --> 02:12:40.630 except for the phone call, of course, 02:12:40.630 --> 02:12:43.129 is that he doesn't know what's going on inside the building. 02:12:43.129 --> 02:12:47.810 He can't see that on a virtual application. 02:12:47.810 --> 02:12:51.550 So we've decided he needs this in everywhere that he goes, 02:12:51.550 --> 02:12:53.490 but we've decided for the scope of the class 02:12:53.490 --> 02:12:56.870 to focus on his school and Boston College. 02:12:56.870 --> 02:12:58.860 Particularly, we're starting with the building 02:12:58.860 --> 02:13:01.550 that he uses every day, which is Fulton Hall. 02:13:01.550 --> 02:13:04.550 One thing about Boston College is that it's very hilly. 02:13:04.550 --> 02:13:07.400 So for Chris, that's really difficult. Some of the paths 02:13:07.400 --> 02:13:10.810 are sort of ramps up the hills, but they're very steep, 02:13:10.810 --> 02:13:13.760 which can be difficult for his chair and also scary. 02:13:13.760 --> 02:13:16.816 If he's going down, he might not be able to stop. 02:13:16.816 --> 02:13:18.940 And there's a lot of stairs on some of these paths. 02:13:18.940 --> 02:13:21.480 So actually he needs to go through buildings sometimes 02:13:21.480 --> 02:13:23.380 and use elevators within the buildings 02:13:23.380 --> 02:13:25.000 to get from a lower level of campus 02:13:25.000 --> 02:13:27.190 to a higher level or vice versa. 02:13:27.190 --> 02:13:28.930 And then he's a very busy students. 02:13:28.930 --> 02:13:31.560 So if he needs a route like that that's not easy 02:13:31.560 --> 02:13:33.620 for him to see online, he might take a long time 02:13:33.620 --> 02:13:35.940 to get to his meetings or his classes, 02:13:35.940 --> 02:13:37.530 and that's a problem for him. 02:13:37.530 --> 02:13:40.130 And the other thing is students on campus don't really 02:13:40.130 --> 02:13:42.790 know these routes, and they're also very busy, 02:13:42.790 --> 02:13:45.490 so it's hard for them to help him out sometimes. 02:13:45.490 --> 02:13:47.550 So our goal is to take the things 02:13:47.550 --> 02:13:52.440 that he uses right now-- Google, Yelp, knowing about stairs, 02:13:52.440 --> 02:13:54.270 and just going out trial and error, 02:13:54.270 --> 02:13:57.470 and finding these warnings by himself-- we're 02:13:57.470 --> 02:14:00.380 trying to take that uncertainty and bring all of these elements 02:14:00.380 --> 02:14:02.420 together into a central application 02:14:02.420 --> 02:14:05.140 that he can just go to this one place, see a map, 02:14:05.140 --> 02:14:07.300 and also go inside buildings and find out 02:14:07.300 --> 02:14:10.710 what things might be difficult. If an elevator isn't working. 02:14:10.710 --> 02:14:12.810 If an automatic door isn't working, 02:14:12.810 --> 02:14:15.420 if there happens to be something in the middle of the hallway 02:14:15.420 --> 02:14:18.950 that could be in his way, or a classroom that has stairs up 02:14:18.950 --> 02:14:21.480 to the seats, so he knows about these things in advance 02:14:21.480 --> 02:14:22.919 and doesn't have to deal with that uncertainty 02:14:22.919 --> 02:14:24.127 that he deals with every day. 02:14:27.626 --> 02:14:29.460 DIRK: So Chris came into this project having 02:14:29.460 --> 02:14:31.542 a pretty good idea of what he wanted us to create, 02:14:31.542 --> 02:14:33.370 and that is an application that presents 02:14:33.370 --> 02:14:37.520 him all of this information in an easily accessible form. 02:14:37.520 --> 02:14:42.010 So our first goal was we needed to narrow down the scope, which 02:14:42.010 --> 02:14:43.890 we decided was Boston College. 02:14:43.890 --> 02:14:45.900 And even more than that, we decided 02:14:45.900 --> 02:14:48.610 to look at three different tiers of information. 02:14:48.610 --> 02:14:52.347 So the first one being at the building level. 02:14:52.347 --> 02:14:53.930 So this would entail essentially being 02:14:53.930 --> 02:14:55.860 able to see the entrances and exits that 02:14:55.860 --> 02:14:57.920 are accessible to buildings, being 02:14:57.920 --> 02:15:03.750 able to see information that is things like potholes or places 02:15:03.750 --> 02:15:07.000 like hills that are hard to access outside of the building. 02:15:07.000 --> 02:15:10.110 The second tier is that of the floor level, 02:15:10.110 --> 02:15:12.360 actually being able to look into the buildings 02:15:12.360 --> 02:15:16.190 and seeing where the locations of elevators 02:15:16.190 --> 02:15:19.650 are, if there's stairs to get places, 02:15:19.650 --> 02:15:22.660 where the accessible bathrooms are located. 02:15:22.660 --> 02:15:26.725 And then the third tier is that of rooms, in particular, 02:15:26.725 --> 02:15:28.350 if there are difficult doors to get in, 02:15:28.350 --> 02:15:30.800 if it's like a lecture hall where the accessible 02:15:30.800 --> 02:15:33.660 seating is, which entrances he can use, 02:15:33.660 --> 02:15:37.700 and being able to present all of that in a tiered format. 02:15:37.700 --> 02:15:40.030 So for our goals, we want to definitely 02:15:40.030 --> 02:15:43.250 be able to do the first and the second level. 02:15:43.250 --> 02:15:44.660 We think those are both feasible. 02:15:44.660 --> 02:15:49.350 We're hoping to get to the third tier as well. 02:15:49.350 --> 02:15:52.310 Beyond that, there are two different aspects 02:15:52.310 --> 02:15:55.570 the application, that being the front end and the back end. 02:15:55.570 --> 02:15:57.690 The front end is the visual display, what 02:15:57.690 --> 02:15:59.740 Chris will actually be using. 02:15:59.740 --> 02:16:04.050 And the back end is where this data that is being 02:16:04.050 --> 02:16:06.350 displayed actually comes from. 02:16:06.350 --> 02:16:08.230 Now, the interesting aspect of this project 02:16:08.230 --> 02:16:12.120 is that because it is navigation-based, 02:16:12.120 --> 02:16:15.180 it's based on buildings and wherever Chris wants to go, 02:16:15.180 --> 02:16:20.930 ultimately his vision is to have this available for everywhere 02:16:20.930 --> 02:16:22.120 he wants to go. 02:16:22.120 --> 02:16:24.836 Obviously, that's not all feasible for the scope 02:16:24.836 --> 02:16:26.090 of this project. 02:16:26.090 --> 02:16:28.790 But we really want to have some sort of method built 02:16:28.790 --> 02:16:33.510 in that allows us to expand to future locations 02:16:33.510 --> 02:16:35.780 and be able to bring in different locations 02:16:35.780 --> 02:16:37.910 to this application. 02:16:37.910 --> 02:16:42.510 So we want to, alongside the front end on display, 02:16:42.510 --> 02:16:44.770 have some sort of method for bringing 02:16:44.770 --> 02:16:48.430 in new places and new data into the application. 02:16:51.350 --> 02:16:53.650 As far as our actual prototypes go, 02:16:53.650 --> 02:16:58.000 we initially started by all four of us creating drawings 02:16:58.000 --> 02:17:01.500 explaining how sort of we saw this application coming 02:17:01.500 --> 02:17:04.420 together, and we presented all of these to Chris 02:17:04.420 --> 02:17:08.496 and discussed with him what he liked about each of them, 02:17:08.496 --> 02:17:11.760 and took the best aspects of each, 02:17:11.760 --> 02:17:16.840 and condensed them down into a singular paper prototype. 02:17:16.840 --> 02:17:22.290 So initially, he liked the map view 02:17:22.290 --> 02:17:24.440 that showed each of the buildings 02:17:24.440 --> 02:17:27.950 with alerts for where the entrances are 02:17:27.950 --> 02:17:31.219 and then being able to have things pop up, 02:17:31.219 --> 02:17:34.040 such as potholes, things outside actually 02:17:34.040 --> 02:17:37.730 getting to the building the he might need to be aware of. 02:17:37.730 --> 02:17:39.860 Then, when he actually clicked on the building, 02:17:39.860 --> 02:17:45.340 it would show up a actual floor plan, 02:17:45.340 --> 02:17:48.620 being able to look at different floors within the building. 02:17:48.620 --> 02:17:53.000 He liked the floor plan because it was very easy to navigate. 02:17:53.000 --> 02:17:57.360 And on top of that, having different notifications, 02:17:57.360 --> 02:17:59.629 different alerts, potentially color-coded 02:17:59.629 --> 02:18:02.629 that show different pieces of information, 02:18:02.629 --> 02:18:07.930 being where there are doors, stairs, elevators, bathrooms, 02:18:07.930 --> 02:18:09.740 all this information that he wanted to be 02:18:09.740 --> 02:18:12.124 able to see very easily marked. 02:18:12.124 --> 02:18:14.540 One of the other big things that he wanted to make sure of 02:18:14.540 --> 02:18:18.930 is that we were presenting just facts about the building. 02:18:18.930 --> 02:18:23.219 He wants the information to be presented in a fairly raw form 02:18:23.219 --> 02:18:26.341 so he can then determine for himself this is somewhere 02:18:26.341 --> 02:18:28.090 I can go, or this is somewhere I can't go. 02:18:30.910 --> 02:18:32.440 As far as actually creating this, 02:18:32.440 --> 02:18:39.799 we decided on a web application because it was easier for us, 02:18:39.799 --> 02:18:42.206 as far as our skills coming in, and it 02:18:42.206 --> 02:18:43.664 was a lot more universal. 02:18:43.664 --> 02:18:46.549 He can access it from his phone, from this computer. 02:18:46.549 --> 02:18:51.410 And then we want to use JavaScript Node Express as far 02:18:51.410 --> 02:18:53.722 as our languages to be able to code that and Mongo 02:18:53.722 --> 02:18:54.847 for our database structure. 02:19:00.600 --> 02:19:02.940 The success metrics that we want to use 02:19:02.940 --> 02:19:05.799 to measure this apply to the user experience 02:19:05.799 --> 02:19:08.379 side of this project, to make sure that Chris is getting 02:19:08.379 --> 02:19:10.080 the most benefit out of the application 02:19:10.080 --> 02:19:11.309 that we're creating. 02:19:11.309 --> 02:19:14.049 And so one of the metrics that we are using 02:19:14.049 --> 02:19:15.680 is the number of clicks it's going 02:19:15.680 --> 02:19:19.809 to take Chris to get a specific item of information 02:19:19.809 --> 02:19:20.530 that he needs. 02:19:20.530 --> 02:19:23.080 So, for instance, starting from the full campus map, 02:19:23.080 --> 02:19:25.490 we want him to only have to click three times 02:19:25.490 --> 02:19:28.230 to get a specific floor plan of a building 02:19:28.230 --> 02:19:30.559 that he wants to go into for class. 02:19:30.559 --> 02:19:33.270 And upon that, click only one more time 02:19:33.270 --> 02:19:35.629 to look at a specific room in that building 02:19:35.629 --> 02:19:38.480 or the specific elevator and to get the information 02:19:38.480 --> 02:19:41.440 that you need to know for that specific facility. 02:19:41.440 --> 02:19:43.250 The second metric that we are going to use 02:19:43.250 --> 02:19:47.299 is how much time it takes for him to gather this information. 02:19:47.299 --> 02:19:49.900 So, as we mentioned earlier, his current methods 02:19:49.900 --> 02:19:52.790 are to call the restaurant he's going to, 02:19:52.790 --> 02:19:55.540 call the disabilities office, look at their website, 02:19:55.540 --> 02:19:57.185 and just look through Google Maps. 02:19:57.185 --> 02:19:58.560 And so we want to be able to time 02:19:58.560 --> 02:20:01.220 how long it takes him to get to find information 02:20:01.220 --> 02:20:03.500 about a specific classroom through those ways, 02:20:03.500 --> 02:20:06.110 and then make sure that it's about 60% less 02:20:06.110 --> 02:20:10.400 time for him to use our website to get that same information. 02:20:10.400 --> 02:20:15.800 The third metric we're using is to allow for uncertainty-- not 02:20:15.800 --> 02:20:18.290 allow for uncertainty, but to reduce as much uncertainty as 02:20:18.290 --> 02:20:19.210 possible. 02:20:19.210 --> 02:20:22.570 And so that way within our website, 02:20:22.570 --> 02:20:25.140 he's not confused when using it, and so we 02:20:25.140 --> 02:20:27.690 want to count how many questions he has, 02:20:27.690 --> 02:20:32.100 and have a little help menu that he can use to clarify things. 02:20:32.100 --> 02:20:33.810 But also just to reduce uncertainty 02:20:33.810 --> 02:20:36.190 within all of his travel procedures 02:20:36.190 --> 02:20:39.220 and to allow him to answer his questions before actually 02:20:39.220 --> 02:20:41.930 going out. 02:20:41.930 --> 02:20:43.860 Now for our future plans of what we're 02:20:43.860 --> 02:20:46.110 doing for the rest of the semester, as Dirk mentioned, 02:20:46.110 --> 02:20:48.850 we're going to split this into the back end and the front end. 02:20:48.850 --> 02:20:51.030 So Dirk and Caroline are going to work on 02:20:51.030 --> 02:20:53.480 in the data aggregation and database set up, 02:20:53.480 --> 02:20:56.680 so getting all the information that we want to display 02:20:56.680 --> 02:21:00.380 and then creating a database structure that we can scope 02:21:00.380 --> 02:21:03.300 later on to add more details-- different types of buildings, 02:21:03.300 --> 02:21:05.580 different floors, different facilities. 02:21:05.580 --> 02:21:08.150 And Phoebe and I are going to be working on the front end 02:21:08.150 --> 02:21:12.550 to increase the user usability of the whole design. 02:21:12.550 --> 02:21:15.660 And since Chris wants actual facts 02:21:15.660 --> 02:21:17.350 that he can interpret for himself, 02:21:17.350 --> 02:21:20.920 we want to have a good balance of images and text 02:21:20.920 --> 02:21:23.140 and just make sure that he's able to use 02:21:23.140 --> 02:21:26.360 this in a clear way. 02:21:26.360 --> 02:21:30.610 The timeline for this semester is until the end of October, 02:21:30.610 --> 02:21:33.410 we want to start our coding process 02:21:33.410 --> 02:21:35.880 and come up with a software prototype, 02:21:35.880 --> 02:21:37.870 and in the first week of November, 02:21:37.870 --> 02:21:39.640 work through our software prototype, 02:21:39.640 --> 02:21:42.760 and by the end of that, have something to present to Chris 02:21:42.760 --> 02:21:44.750 and have him actually test it and use it 02:21:44.750 --> 02:21:46.432 so that way we can revise and reiterate 02:21:46.432 --> 02:21:47.390 and keep going with it. 02:21:47.390 --> 02:21:49.150 And by the end of November, we want 02:21:49.150 --> 02:21:52.150 to have our final version that we can continue 02:21:52.150 --> 02:21:53.633 to reiterate throughout. 02:21:53.633 --> 02:21:54.216 And that's it. 02:21:54.216 --> 02:21:54.799 Any questions? 02:22:01.252 --> 02:22:03.710 PROFESSOR 5: All right, we have four minutes for questions. 02:22:03.710 --> 02:22:05.520 Have you tried to work with Boston College 02:22:05.520 --> 02:22:07.982 to get the actual floor plans, like PDFs and things? 02:22:07.982 --> 02:22:09.465 Do you have all that? 02:22:09.465 --> 02:22:10.840 STUDENT 6: Yes, so we're actually 02:22:10.840 --> 02:22:13.880 in contact with Boston College Disabilities Office right now, 02:22:13.880 --> 02:22:16.900 and they are working with the head architect 02:22:16.900 --> 02:22:17.970 to get the information. 02:22:17.970 --> 02:22:21.250 Right now we're just working through the legal procedures 02:22:21.250 --> 02:22:22.690 of which information he's actually 02:22:22.690 --> 02:22:25.107 allowed to give us and so what we're allowed to display. 02:22:25.107 --> 02:22:26.690 PROFESSOR 5: MIT has a whole database. 02:22:26.690 --> 02:22:28.690 If you ever want MIT, I'll show you where it is. 02:22:33.320 --> 02:22:35.981 AUDIENCE: How does he update it, like if a pothole is fixed. 02:22:39.460 --> 02:22:43.300 DIRK: Yeah, so that's an area that we're still 02:22:43.300 --> 02:22:44.650 trying to figure out. 02:22:44.650 --> 02:22:46.490 We've had a couple a different ideas, 02:22:46.490 --> 02:22:49.480 one being trying to crowdsource that out somehow, 02:22:49.480 --> 02:22:52.880 having the ability in the app for users, 02:22:52.880 --> 02:22:56.020 if they notice something, to put that in as an alert. 02:22:56.020 --> 02:22:58.790 We've thought about contacting Boston College, 02:22:58.790 --> 02:23:01.800 like the maintenance or the facilities office, 02:23:01.800 --> 02:23:04.230 and if their staff notices things, 02:23:04.230 --> 02:23:06.070 having a way to put that in. 02:23:06.070 --> 02:23:08.140 So those are a couple ideas, and we're still 02:23:08.140 --> 02:23:09.986 trying to figure out exactly how the best 02:23:09.986 --> 02:23:10.985 way to go about that is. 02:23:13.660 --> 02:23:17.890 AUDIENCE: Excuse me, we have a colleague 02:23:17.890 --> 02:23:21.100 in New York City that's done, in the past, 02:23:21.100 --> 02:23:24.170 maybe two or three years ago, like a Yelp for people 02:23:24.170 --> 02:23:28.991 with disabilities for accessibility to buildings. 02:23:28.991 --> 02:23:33.410 I'm fairly sure the site no longer as fresh 02:23:33.410 --> 02:23:36.830 as it was during his NYU [? ITP ?] days, 02:23:36.830 --> 02:23:39.740 but we could put you in touch with them 02:23:39.740 --> 02:23:42.911 and see how they've updated or how they basically populated 02:23:42.911 --> 02:23:44.464 that information. 02:23:44.464 --> 02:23:45.797 DIRK: Yeah, that would be great. 02:23:51.712 --> 02:23:53.230 CIMMY: Hi, we're Team Felicity. 02:23:53.230 --> 02:23:54.060 I'm Cimmy. 02:23:54.060 --> 02:23:54.620 This Ari. 02:23:54.620 --> 02:23:59.530 This is Becca, and we're Team Felicity. 02:23:59.530 --> 02:24:02.930 This is our mid-semester review. 02:24:02.930 --> 02:24:05.210 Today we're going to show you our video, talk 02:24:05.210 --> 02:24:07.530 about the HAAT model for Felicity, 02:24:07.530 --> 02:24:10.710 our project vision, and our accomplishments so far. 02:24:10.710 --> 02:24:13.320 So we'll start off by showing you our video. 02:24:13.320 --> 02:24:15.440 [VIDEO PLAYBACK] 02:24:15.440 --> 02:24:17.940 -Let's like together develop a prototype 02:24:17.940 --> 02:24:21.890 of assistive technology that you will find useful. 02:24:21.890 --> 02:24:25.400 -I have a disease called neurofibromatosis, 02:24:25.400 --> 02:24:29.370 which causes tumors to build up in the brain and spine. 02:24:29.370 --> 02:24:32.570 I had surgery last February in 2014 02:24:32.570 --> 02:24:35.450 to remove the tumor on this side, which also took out 02:24:35.450 --> 02:24:41.560 my hearing nerve completely, so now absolutely profoundly 02:24:41.560 --> 02:24:43.790 deaf on each side. 02:24:43.790 --> 02:24:48.775 I also have a tumor on my optic nerve behind this eye. 02:24:51.720 --> 02:24:54.420 My vision, I have days where my vision is perfectly fine, 02:24:54.420 --> 02:24:56.520 and I can see everything clearly. 02:24:56.520 --> 02:24:59.830 Then I have other days where things are just like really 02:24:59.830 --> 02:25:05.220 cloudy and I lose depth perception 02:25:05.220 --> 02:25:07.850 or have trouble seeing like walk signals, 02:25:07.850 --> 02:25:12.590 like seeing whether it's white or red or flashing. 02:25:12.590 --> 02:25:17.460 And I had a really close call a few weeks ago over in Fenway, 02:25:17.460 --> 02:25:20.230 where, because I know I'm impaired, 02:25:20.230 --> 02:25:23.370 so I'm looking for the light, and I still kind of like 02:25:23.370 --> 02:25:26.220 look because I just don't trust anyone. 02:25:26.220 --> 02:25:31.790 But I look for the light, and then a big truck 02:25:31.790 --> 02:25:33.600 comes right towards me. 02:25:33.600 --> 02:25:34.770 It was terrifying. 02:25:34.770 --> 02:25:37.950 I pretty much rely on like reading people's lips, 02:25:37.950 --> 02:25:39.570 and then I'll take out pen and paper 02:25:39.570 --> 02:25:42.390 if it's like something that's really, really important 02:25:42.390 --> 02:25:46.280 or if I'm just particularly tired 02:25:46.280 --> 02:25:48.130 and don't have the energy. 02:25:51.335 --> 02:25:53.600 I'm moving to a new apartment on October 1st, 02:25:53.600 --> 02:25:58.290 and they're installing flashing smoke detectors, CO detector, 02:25:58.290 --> 02:25:59.170 and a doorbell. 02:25:59.170 --> 02:26:01.949 I've never used a flashing doorbell before, 02:26:01.949 --> 02:26:02.990 so that will be exciting. 02:26:06.265 --> 02:26:07.140 I can feel the vibes. 02:26:16.618 --> 02:26:19.000 And I have like a computer that I watch 02:26:19.000 --> 02:26:20.440 captioned DVDs on sometimes. 02:26:20.440 --> 02:26:23.495 I don't have a TV or radio. 02:26:28.530 --> 02:26:34.640 I set my phone to vibrate all the time for when I get emails 02:26:34.640 --> 02:26:36.170 and so forth. 02:26:36.170 --> 02:26:41.626 If I call you, then they'll be a relay operator. 02:26:41.626 --> 02:26:42.328 -I'm doing fine. 02:26:42.328 --> 02:26:43.078 Thanks for asking. 02:26:43.078 --> 02:26:43.578 Go ahead. 02:26:51.810 --> 02:26:53.020 -Hi, I'm Ari. 02:26:53.020 --> 02:26:54.210 Hi, I'm Cimmy. 02:26:54.210 --> 02:26:56.565 Hey, I'm Becca, and we're Team Felicity. 02:26:56.565 --> 02:26:59.330 We've gotten to know Felicity a lot better through our meetings 02:26:59.330 --> 02:27:01.159 and have come up with a lot of neat ideas. 02:27:01.159 --> 02:27:02.284 We're excited to get going. 02:27:07.980 --> 02:27:11.370 [END PLAYBACK] 02:27:11.370 --> 02:27:13.515 CIMMY: So, as you can see, Felicity 02:27:13.515 --> 02:27:17.480 has neurofibromatosis, which is a genetic disorder that 02:27:17.480 --> 02:27:20.530 can causes tumors to grow on nerve tissue. 02:27:20.530 --> 02:27:24.340 She had a few surgeries to take away some tumors, 02:27:24.340 --> 02:27:29.220 and due to those surgeries, she lost a lot of her vision. 02:27:29.220 --> 02:27:30.880 She can use her peripherals, and she's 02:27:30.880 --> 02:27:32.465 profoundly deaf on both sides. 02:27:36.400 --> 02:27:38.510 The activities that Felicity likes to do 02:27:38.510 --> 02:27:42.270 are she really enjoys walking around Boston. 02:27:42.270 --> 02:27:46.400 She also actually has routine doctor's appointments, 02:27:46.400 --> 02:27:51.340 so she's usually between our home and the hospital. 02:27:51.340 --> 02:27:55.220 And in terms of context, Felicity 02:27:55.220 --> 02:27:57.520 lives alone at her apartment. 02:27:57.520 --> 02:28:01.350 She is unemployed and frequents doctors 02:28:01.350 --> 02:28:03.170 offices and the hospital. 02:28:03.170 --> 02:28:06.240 And she leaves the house minimally during evening. 02:28:06.240 --> 02:28:08.160 She doesn't like to be out at night. 02:28:08.160 --> 02:28:11.520 And she happens to be very open to letting 02:28:11.520 --> 02:28:14.540 people know that she is deaf and using 02:28:14.540 --> 02:28:17.520 assistive technology between that. 02:28:20.250 --> 02:28:22.770 In terms of assistive technology that Felicity already 02:28:22.770 --> 02:28:26.100 uses, so to communicate with her, 02:28:26.100 --> 02:28:31.380 we have been using a notepad or a laptop with size 36 font 02:28:31.380 --> 02:28:33.510 so she can read it. 02:28:33.510 --> 02:28:37.890 And she also uses her iPhone, as you saw on the video. 02:28:37.890 --> 02:28:39.590 She receives emails from her doctor 02:28:39.590 --> 02:28:42.080 when she's out the doctor's office to notify her 02:28:42.080 --> 02:28:45.550 when they're ready for her. 02:28:45.550 --> 02:28:49.620 And she uses a Sprint relay app for phone calls and so on. 02:28:49.620 --> 02:28:52.850 And, as you saw on the video, a flashing smoke detector, 02:28:52.850 --> 02:28:55.300 and a CO alarm are installed in her home, 02:28:55.300 --> 02:29:02.070 and she also has a flashing doorbell, which the noise is 02:29:02.070 --> 02:29:05.430 loud enough that she actually feel the vibrations when 02:29:05.430 --> 02:29:08.160 they're occurring. 02:29:08.160 --> 02:29:12.200 So now I'll switch over to Becca. 02:29:12.200 --> 02:29:14.080 BECCA: So I guess along the way of getting 02:29:14.080 --> 02:29:16.420 to know Felicity and her daily life, 02:29:16.420 --> 02:29:18.530 we like discussed a lot of activities 02:29:18.530 --> 02:29:22.670 that we could potentially help her design an AT solution for. 02:29:22.670 --> 02:29:25.340 We had to kind of whittle it down to one motivation 02:29:25.340 --> 02:29:27.702 that we could center a project around. 02:29:27.702 --> 02:29:29.660 And so the problem that we're going to focus on 02:29:29.660 --> 02:29:32.210 is that Felicity can't always detect when events occur 02:29:32.210 --> 02:29:34.190 because she's mostly deaf. 02:29:34.190 --> 02:29:36.340 And so these include like if people call her name, 02:29:36.340 --> 02:29:40.000 either at a cafe or at the doctor's office, 02:29:40.000 --> 02:29:42.890 or if a laundry machine's done, or when 02:29:42.890 --> 02:29:44.920 she's going on her walks, she can't hear cars 02:29:44.920 --> 02:29:47.319 honking from incoming traffic. 02:29:47.319 --> 02:29:48.860 And so these are all situations where 02:29:48.860 --> 02:29:50.624 somehow RET could help her. 02:29:50.624 --> 02:29:52.040 And so our goal for the project is 02:29:52.040 --> 02:29:54.930 to develop an AT that will notify Felicity 02:29:54.930 --> 02:29:58.280 when particular events happen. 02:29:58.280 --> 02:30:01.130 So this is variation came particularly from an email 02:30:01.130 --> 02:30:04.845 that Felicity sent to us with this hearing dogs video in it. 02:30:04.845 --> 02:30:06.720 I guess we don't have time to show the video, 02:30:06.720 --> 02:30:10.619 but the idea was just that she saw this hearing dog video, 02:30:10.619 --> 02:30:12.160 and at the end of her email she said, 02:30:12.160 --> 02:30:13.785 it would be really cool if I could have 02:30:13.785 --> 02:30:15.740 my own handheld hearing dog. 02:30:15.740 --> 02:30:19.460 And so that was a cool step towards, for us, 02:30:19.460 --> 02:30:22.450 to find a solution for her. 02:30:22.450 --> 02:30:24.720 And so throughout so far, we've currently 02:30:24.720 --> 02:30:27.140 been going through an iterative design process 02:30:27.140 --> 02:30:29.210 to kind of whittle go down a solution 02:30:29.210 --> 02:30:31.100 and find something that works for her. 02:30:31.100 --> 02:30:32.790 We've been using low fidelity prototypes 02:30:32.790 --> 02:30:35.640 to get feedback from Felicity, even to narrow down 02:30:35.640 --> 02:30:37.120 for our project solution. 02:30:37.120 --> 02:30:40.410 And as we'll talk about a little later, 02:30:40.410 --> 02:30:42.580 our initial design process showed us 02:30:42.580 --> 02:30:46.214 that our project problem changed after discussions with her. 02:30:46.214 --> 02:30:48.380 So this is just some example of some of the sketches 02:30:48.380 --> 02:30:49.360 we've done. 02:30:49.360 --> 02:30:53.210 In this example, we had two parts of a solution. 02:30:53.210 --> 02:30:56.135 One was a button that someone could pass for her attention, 02:30:56.135 --> 02:30:58.260 and the other would be some sort of wearable device 02:30:58.260 --> 02:31:01.580 that would vibrate, telling her once like this button has 02:31:01.580 --> 02:31:02.159 been pushed. 02:31:02.159 --> 02:31:03.950 Now Ari is going to share a little bit more 02:31:03.950 --> 02:31:06.325 about our initial problem statement and problem overview. 02:31:11.740 --> 02:31:15.140 ARI: Right, so the first project we wanted to tackle 02:31:15.140 --> 02:31:19.270 was trying to let Felicity know when someone called out 02:31:19.270 --> 02:31:20.410 her name. 02:31:20.410 --> 02:31:23.880 And because she can't hear and she has limited vision, 02:31:23.880 --> 02:31:28.100 it's pretty difficult if she was in like a waiting 02:31:28.100 --> 02:31:32.150 room or the doctor's office or in a classroom 02:31:32.150 --> 02:31:35.190 to like figure out if someone's trying to contact her. 02:31:35.190 --> 02:31:39.550 So the idea we came up with was rather than having someone 02:31:39.550 --> 02:31:43.390 try to call out their name, we would have them have a button 02:31:43.390 --> 02:31:44.970 that they could press. 02:31:44.970 --> 02:31:46.950 And when they press the button, it 02:31:46.950 --> 02:31:49.159 would contact Felicity that they were 02:31:49.159 --> 02:31:50.325 trying to get her attention. 02:31:53.170 --> 02:31:57.110 So this is the kind of overview of that design. 02:31:57.110 --> 02:31:59.570 We have a button that someone could press. 02:31:59.570 --> 02:32:02.410 It would send a message to her iPhone, 02:32:02.410 --> 02:32:04.490 and then the iPhone would display 02:32:04.490 --> 02:32:06.110 some sort of notification. 02:32:06.110 --> 02:32:08.290 And then we'd also have a wearable device 02:32:08.290 --> 02:32:10.837 that she could use, and they both display notifications. 02:32:10.837 --> 02:32:12.295 So kind of a two-step notification. 02:32:18.310 --> 02:32:21.510 Luckily, we really worked on doing iterative design 02:32:21.510 --> 02:32:23.720 and also user-centered design because we 02:32:23.720 --> 02:32:25.810 try talking with her about how well does 02:32:25.810 --> 02:32:29.630 she think this will work, and she really liked this idea. 02:32:29.630 --> 02:32:33.670 But she was concerned about other people using it. 02:32:33.670 --> 02:32:36.340 And so one thing we tried talking with her 02:32:36.340 --> 02:32:38.130 is what would you like more? 02:32:38.130 --> 02:32:40.580 And particularly, she would want something 02:32:40.580 --> 02:32:44.720 that she could use possibly more often and also independently 02:32:44.720 --> 02:32:48.460 because this original project involves two clients-- Felicity 02:32:48.460 --> 02:32:50.920 and whoever we give the button to. 02:32:50.920 --> 02:32:52.890 And so the new focus of our project 02:32:52.890 --> 02:32:56.200 changed to try and make some sort of way 02:32:56.200 --> 02:32:59.030 to make sound emitting appliances within her home 02:32:59.030 --> 02:33:01.643 accessible for Felicity. 02:33:04.960 --> 02:33:07.510 So basically within Felicity's apartment 02:33:07.510 --> 02:33:10.680 she has a few different household appliances 02:33:10.680 --> 02:33:13.760 that she doesn't know when they're done working. 02:33:13.760 --> 02:33:16.680 In particular, the laundry machine, when it's done, 02:33:16.680 --> 02:33:19.910 it just triggers a beep, and it doesn't have a timer. 02:33:19.910 --> 02:33:23.450 So she would like a way to know when it's finished. 02:33:23.450 --> 02:33:26.720 And basically the idea we have is 02:33:26.720 --> 02:33:28.380 we could have some sort of device 02:33:28.380 --> 02:33:31.530 that she could place next to the household appliance. 02:33:31.530 --> 02:33:33.740 And then when the appliance is finished 02:33:33.740 --> 02:33:37.240 doing whatever its task is, it will emit some noise, 02:33:37.240 --> 02:33:39.910 and this device would pick up on it 02:33:39.910 --> 02:33:42.330 and send a signal to Felicity to let 02:33:42.330 --> 02:33:44.900 her know that whatever the household appliance 02:33:44.900 --> 02:33:48.470 task has completed. 02:33:48.470 --> 02:33:52.230 So again, we kind of kept last half of the project 02:33:52.230 --> 02:33:56.200 that we started scoping out and just talking about. 02:33:56.200 --> 02:33:58.170 And instead, now we have a microphone 02:33:58.170 --> 02:34:00.920 that would be placed next to the household appliance, 02:34:00.920 --> 02:34:06.310 and then the microphone would be sending sound to the iPhone. 02:34:06.310 --> 02:34:08.510 And within the iPhone we could have an application 02:34:08.510 --> 02:34:15.390 that would notify when the sound of the appliance finishing 02:34:15.390 --> 02:34:17.030 has happened. 02:34:17.030 --> 02:34:23.000 So for the implementation we decide 02:34:23.000 --> 02:34:26.930 to use Bluetooth because this is in her apartment. 02:34:26.930 --> 02:34:30.190 It's less than 30 feet, and also Felicity 02:34:30.190 --> 02:34:33.140 leaves her phone plugged in while she's at her house. 02:34:33.140 --> 02:34:36.890 So we're not too worried about that part. 02:34:36.890 --> 02:34:40.600 And then right now we're all working on developing an iPhone 02:34:40.600 --> 02:34:42.916 application for detecting the sound and also 02:34:42.916 --> 02:34:43.999 the Bluetooth integration. 02:34:48.730 --> 02:34:50.450 So these are kind of the hardware pieces 02:34:50.450 --> 02:34:52.140 we've been also testing out. 02:34:52.140 --> 02:34:55.390 The first one was a Bluetooth camera shutter button, 02:34:55.390 --> 02:34:57.790 and we also have a headset that we're just 02:34:57.790 --> 02:35:00.641 using as a microphone because we already have it, 02:35:00.641 --> 02:35:02.682 and we're just trying to do low-cost prototyping. 02:35:08.067 --> 02:35:10.400 BECCA: So to talk a little bit about the success metrics 02:35:10.400 --> 02:35:13.590 that we set up for our project, for the technical side, 02:35:13.590 --> 02:35:15.736 we broke down our project in two parts. 02:35:15.736 --> 02:35:18.110 There's going to be a noise detection to the iPhone part, 02:35:18.110 --> 02:35:20.980 and then the iPhone to the notification part. 02:35:20.980 --> 02:35:23.010 And so from there, we have like two activities-- 02:35:23.010 --> 02:35:25.590 the amount of noise that this microphone 02:35:25.590 --> 02:35:29.300 could withstand before, and also correctly detect the appliance. 02:35:29.300 --> 02:35:32.370 And those are kind of our levels of how good 02:35:32.370 --> 02:35:34.530 it would be, where level two would be ideal, 02:35:34.530 --> 02:35:37.599 and level zero is not actually doing its job, and then 02:35:37.599 --> 02:35:39.140 the number of noises it would detect. 02:35:39.140 --> 02:35:43.587 And then for the iPhone to notification part, 02:35:43.587 --> 02:35:45.420 the success metric would be like the percent 02:35:45.420 --> 02:35:47.870 times the notification actually succeeds and is correctly 02:35:47.870 --> 02:35:50.972 pinging Felicity. 02:35:50.972 --> 02:35:52.680 And then we have for overall performance, 02:35:52.680 --> 02:35:54.596 I guess the best way to measure our success is 02:35:54.596 --> 02:35:57.050 just how many appliances we can actually adapt this to. 02:35:57.050 --> 02:35:59.830 And so the laundry machine, dryer, toaster oven, 02:35:59.830 --> 02:36:02.360 and tea pot are just five things that we 02:36:02.360 --> 02:36:05.430 are kind of aiming towards being able to make this for. 02:36:05.430 --> 02:36:07.705 And also we're considering maintenance as well. 02:36:07.705 --> 02:36:09.080 Once we finish with this project, 02:36:09.080 --> 02:36:11.150 we want to make sure that all the parts of our project 02:36:11.150 --> 02:36:13.150 are replaceable so that Felicity can continue 02:36:13.150 --> 02:36:15.580 to use it once we're not there. 02:36:15.580 --> 02:36:20.104 From the UI perspective side, the best way quantitatively 02:36:20.104 --> 02:36:21.770 to measure this is just the average time 02:36:21.770 --> 02:36:24.370 it would take to set up a notification for a machine task 02:36:24.370 --> 02:36:27.710 that she has, and then also her own perspective 02:36:27.710 --> 02:36:29.312 about whether or not she things the UI 02:36:29.312 --> 02:36:30.520 is intuitive and easy to use. 02:36:35.750 --> 02:36:38.240 CIMMY: And in terms of our project development so far, 02:36:38.240 --> 02:36:42.280 we have purchased at Bluetooth camera shutter remote button, 02:36:42.280 --> 02:36:48.310 which was actually for our previous idea, 02:36:48.310 --> 02:36:52.760 in order for Felicity to be able to give a button to someone 02:36:52.760 --> 02:36:57.020 so that they could press it to a signal her phone 02:36:57.020 --> 02:36:59.890 that she's getting a signal. 02:36:59.890 --> 02:37:03.160 And we started developing an iPhone application 02:37:03.160 --> 02:37:05.780 for the project that we've moved towards, 02:37:05.780 --> 02:37:09.090 and now we're investigating wearable devices that Felicity 02:37:09.090 --> 02:37:12.000 could wear for notification. 02:37:12.000 --> 02:37:14.020 And we're leaning more towards the side 02:37:14.020 --> 02:37:17.690 of some sort of wrist wearable or something 02:37:17.690 --> 02:37:20.020 that she could hold. 02:37:20.020 --> 02:37:22.790 And in terms of our project's plans and timelines, 02:37:22.790 --> 02:37:25.550 this is just a general timeline that we have. 02:37:25.550 --> 02:37:30.810 We hope to get her iPhone app working at a low scale 02:37:30.810 --> 02:37:33.200 so that we can just have her iPhone connected 02:37:33.200 --> 02:37:36.000 with some microphone and see how well that works, if we're 02:37:36.000 --> 02:37:39.320 getting a vibration notification, 02:37:39.320 --> 02:37:42.770 gather appliances and a sound library by November 7th, 02:37:42.770 --> 02:37:44.270 and then test the app functionality. 02:37:44.270 --> 02:37:49.500 We want to focus a lot on having Felicity test out the app 02:37:49.500 --> 02:37:51.980 and see how well it works. 02:37:51.980 --> 02:37:57.250 And then probably by the 28th of November, 02:37:57.250 --> 02:38:02.500 we want to clean up the final project and work on the UI 02:38:02.500 --> 02:38:05.450 and fix bugs on the last week. 02:38:09.432 --> 02:38:09.932 Thank you. 02:38:12.416 --> 02:38:13.916 PROFESSOR 4: Questions and comments? 02:38:21.087 --> 02:38:23.378 AUDIENCE: So for the appliances you were talking about, 02:38:23.378 --> 02:38:29.305 like tea pot, laundry, and [INAUDIBLE], 02:38:29.305 --> 02:38:31.346 would it make more sense to use a timer for that? 02:38:31.346 --> 02:38:34.334 Because each of those appliances are pretty set 02:38:34.334 --> 02:38:37.977 timings for the [INAUDIBLE]. 02:38:37.977 --> 02:38:40.310 Would that be easier than detecting a sound [INAUDIBLE]? 02:38:43.796 --> 02:38:46.226 BECCA: So that's something that we asked Felicity about, 02:38:46.226 --> 02:38:47.350 and I think she-- oh sorry. 02:38:47.350 --> 02:38:48.950 That is something we asked, we brought up 02:38:48.950 --> 02:38:50.991 when we were talking about this is with Felicity. 02:38:50.991 --> 02:38:54.100 But, I think, one thing is like you don't always 02:38:54.100 --> 02:38:56.610 remember to set up the timer, or sometimes 02:38:56.610 --> 02:38:59.042 you just like run into something else that you do. 02:38:59.042 --> 02:39:01.250 And so you told yourself, oh, I was going to do that. 02:39:01.250 --> 02:39:03.159 But she just forgets. 02:39:03.159 --> 02:39:05.700 And also when she's home, she doesn't keep her iPhone on her. 02:39:05.700 --> 02:39:07.940 So she usually has it plugged in, 02:39:07.940 --> 02:39:12.260 so if she can't hear the alarm, or even if it was vibrating, 02:39:12.260 --> 02:39:14.335 she just doesn't know if she's in another room 02:39:14.335 --> 02:39:17.409 or she's taking a nap to actually go and check on it. 02:39:17.409 --> 02:39:19.492 So I think when we did introduce this idea to her, 02:39:19.492 --> 02:39:21.890 and we told her, well, there are like other alternatives that 02:39:21.890 --> 02:39:23.390 seem more feasible, she really liked 02:39:23.390 --> 02:39:25.621 the idea of having something that's preferably 02:39:25.621 --> 02:39:26.870 a wearable that just vibrates. 02:39:26.870 --> 02:39:28.890 Then she doesn't have to be thinking about it. 02:39:28.890 --> 02:39:30.580 But she'll know exactly when it's ringing that she 02:39:30.580 --> 02:39:31.663 should go back and see it. 02:39:33.900 --> 02:39:35.400 AUDIENCE: Why do you need the phone? 02:39:38.067 --> 02:39:40.400 BECCA: So I think first in terms of like implementation, 02:39:40.400 --> 02:39:43.190 it's a bit easier to have an iPhone 02:39:43.190 --> 02:39:47.800 app be the one that's sending the Bluetooth signal back 02:39:47.800 --> 02:39:48.830 to the wearable. 02:39:48.830 --> 02:39:51.940 And also in terms of modularity, I think, 02:39:51.940 --> 02:39:54.610 it would be a more complicated hardware solution 02:39:54.610 --> 02:39:57.190 if it was intelligently picking up just 02:39:57.190 --> 02:40:00.045 to send to the specific hardware device. 02:40:00.045 --> 02:40:07.160 I'm sorry, from like sound detector to the wearable, 02:40:07.160 --> 02:40:09.530 it's two more complicated hardware solutions. 02:40:09.530 --> 02:40:12.570 And so then it's the question of maintenance, 02:40:12.570 --> 02:40:14.750 like how is she going to replace these more 02:40:14.750 --> 02:40:15.960 complicated solutions? 02:40:15.960 --> 02:40:17.949 But instead, we're using two kind 02:40:17.949 --> 02:40:20.490 of just all they have to do is either send a Bluetooth signal 02:40:20.490 --> 02:40:22.350 and then receive a Bluetooth signal, 02:40:22.350 --> 02:40:25.460 and that's like two much cheaper hardware pieces for us to get. 02:40:25.460 --> 02:40:27.141 And she could always replace those. 02:40:27.141 --> 02:40:28.640 And then the iPhone app is something 02:40:28.640 --> 02:40:29.940 that she'd already have. 02:40:29.940 --> 02:40:31.950 AUDIENCE: How much is a Bluetooth switch? 02:40:31.950 --> 02:40:33.790 BECCA: Yeah, so what we looked at so far, 02:40:33.790 --> 02:40:36.810 like out-of-the0box solutions to be like $30 to $40. 02:40:41.076 --> 02:40:42.492 AUDIENCE: If you skip the phone, I 02:40:42.492 --> 02:40:48.110 guess, you would be able to use an RF link for $5? 02:40:48.110 --> 02:40:51.010 BECCA: OK, but would that be able to know-- 02:40:51.010 --> 02:40:53.030 like would the notification collector, 02:40:53.030 --> 02:40:56.140 I mean the sound detector, know to send it exactly 02:40:56.140 --> 02:41:01.535 to this Bluetooth wearable? 02:41:01.535 --> 02:41:04.191 Or is that a Bluetooth [INAUDIBLE] RF? 02:41:04.191 --> 02:41:06.190 ARI: I guess one thing we'd also like to include 02:41:06.190 --> 02:41:09.770 is one of the reasons we kind of stuck with iPhone 02:41:09.770 --> 02:41:13.350 is we were interested in finding commercial products that we 02:41:13.350 --> 02:41:16.968 don't have to customize any of the hardware, 02:41:16.968 --> 02:41:18.384 especially with the button design. 02:41:18.384 --> 02:41:21.510 If it broke, she could easily purchase a new one. 02:41:21.510 --> 02:41:25.110 Like those buttons that we first shows, they're under $10 02:41:25.110 --> 02:41:26.910 to get similar designs. 02:41:26.910 --> 02:41:28.705 So what we're really hoping to get 02:41:28.705 --> 02:41:31.515 is something that will work after we're 02:41:31.515 --> 02:41:33.580 done with the class. 02:41:33.580 --> 02:41:35.260 So you can purchase these designs 02:41:35.260 --> 02:41:38.390 and keep making designs that work with the iPhone, then 02:41:38.390 --> 02:41:39.760 why don't we capitalize on that? 02:41:42.533 --> 02:41:44.574 PROFESSOR 4: So, Leonard, do you have a question? 02:41:49.286 --> 02:41:51.160 PROFESSOR 5: Did you make an actual prototype 02:41:51.160 --> 02:41:52.825 for-- what was your prototype? 02:41:56.702 --> 02:41:58.660 BECCA: It was mostly so far just like sketches. 02:41:58.660 --> 02:42:00.296 It was mostly sketches to show her 02:42:00.296 --> 02:42:02.265 like, OK, these are three pieces, two pieces, 02:42:02.265 --> 02:42:04.275 or like, these are kinds of pieces we're talking about, 02:42:04.275 --> 02:42:06.441 and then like whether or not you even like the idea. 02:42:06.441 --> 02:42:08.350 PROFESSOR 5: Sort of like a storyboard? 02:42:08.350 --> 02:42:09.766 BECCA: Yeah, and user [? flows. ?] 02:42:12.060 --> 02:42:15.434 ARI: And we also brought the physical hardware 02:42:15.434 --> 02:42:18.226 of that button to kind of see how she liked it, would 02:42:18.226 --> 02:42:20.067 she feel like it's OK to use. 02:42:20.067 --> 02:42:22.150 PROFESSOR 5: So you're going to run with that one? 02:42:22.150 --> 02:42:24.191 The you bought, is that what you're going to use, 02:42:24.191 --> 02:42:26.020 or are you going to use something else? 02:42:26.020 --> 02:42:27.520 ARI: No, we're planning on switching 02:42:27.520 --> 02:42:29.650 to try to make something that only works 02:42:29.650 --> 02:42:32.400 with her independently because we're concerned about having 02:42:32.400 --> 02:42:34.830 the extra client that couldn't really control, 02:42:34.830 --> 02:42:36.900 make sure they were on board. 02:42:36.900 --> 02:42:38.900 BECCA: So it's like microphone, iPhone, and then 02:42:38.900 --> 02:42:41.375 wearable or something to like [INAUDIBLE]. 02:42:43.725 --> 02:42:45.350 PROFESSOR 5: OK, I think we're at time. 02:42:45.350 --> 02:42:46.370 Thank you very much. 02:42:53.950 --> 02:42:56.370 EANN: Hi, we're Team Don, and my name is Eann. 02:42:56.370 --> 02:42:58.814 This is Christina, and over here is Jan. 02:42:58.814 --> 02:43:00.730 First, we'd like to tell you a little bit more 02:43:00.730 --> 02:43:01.820 about our client. 02:43:01.820 --> 02:43:05.180 Our client's name is Don, and he is a male senior citizen 02:43:05.180 --> 02:43:06.320 who currently lives alone. 02:43:06.320 --> 02:43:09.080 He's a strong advocate for support groups, 02:43:09.080 --> 02:43:12.610 and he constantly tells us about how he goes to conferences 02:43:12.610 --> 02:43:15.870 and speaks to health professionals. 02:43:15.870 --> 02:43:19.260 And he suffered from polio during his childhood, 02:43:19.260 --> 02:43:21.340 and that is affected his left leg. 02:43:21.340 --> 02:43:25.420 But in 2002, he also suffer from a stroke 02:43:25.420 --> 02:43:27.800 that affected the right hemisphere of his brain. 02:43:27.800 --> 02:43:31.300 So currently he has limited use of his left side and especially 02:43:31.300 --> 02:43:34.510 his left arm, and this has also resulted 02:43:34.510 --> 02:43:37.010 in cognitive difficulties, especially 02:43:37.010 --> 02:43:39.336 in the late afternoon or early afternoon, 02:43:39.336 --> 02:43:41.460 whenever sometimes it's a little bit harder for him 02:43:41.460 --> 02:43:45.340 to process and to focus and to just kind of stay 02:43:45.340 --> 02:43:47.390 on track with whatever conversation 02:43:47.390 --> 02:43:48.700 he's currently engaged in. 02:43:51.280 --> 02:43:54.450 From our very first meeting, we knew that Don loved food, 02:43:54.450 --> 02:43:55.650 and he loved to cook. 02:43:55.650 --> 02:43:57.100 So one of our very first questions 02:43:57.100 --> 02:43:59.600 was, what's your favorite flavor of ice cream? 02:43:59.600 --> 02:44:03.210 And this kind of transcended into this conversation of food, 02:44:03.210 --> 02:44:05.400 and we discovered that Don was actually 02:44:05.400 --> 02:44:09.790 a food catering manager prior to his disability. 02:44:09.790 --> 02:44:13.050 And when you first started at his job at KFC, 02:44:13.050 --> 02:44:16.690 he learned about his passion for cooking and expressing himself 02:44:16.690 --> 02:44:17.710 through food. 02:44:17.710 --> 02:44:20.140 And so as a result, he still cooks, 02:44:20.140 --> 02:44:22.737 and he constantly talks about different recipes. 02:44:22.737 --> 02:44:24.570 And we got the opportunity to make omelettes 02:44:24.570 --> 02:44:25.740 with him one day. 02:44:25.740 --> 02:44:28.890 And so with his left hand, it typically is stable, 02:44:28.890 --> 02:44:31.050 and he uses his right hand to cook. 02:44:31.050 --> 02:44:33.150 And with his left hand held typically either 02:44:33.150 --> 02:44:35.710 brace apart or hold onto a cheese package, 02:44:35.710 --> 02:44:37.030 and rip open the top. 02:44:37.030 --> 02:44:39.340 But typically, it's only just his right arm 02:44:39.340 --> 02:44:42.175 that he uses, and it's essentially 02:44:42.175 --> 02:44:47.560 his only method of cooking-- or only manner of cooking. 02:44:47.560 --> 02:44:52.250 And so this you can see is in his actual apartment. 02:44:52.250 --> 02:44:55.670 We got the opportunity to go visit Don in his apartment 02:44:55.670 --> 02:44:59.580 and kind of see where he lives and see where he actually 02:44:59.580 --> 02:45:00.970 takes the time to cook. 02:45:00.970 --> 02:45:02.630 And so we noticed that is apartment 02:45:02.630 --> 02:45:05.420 is actually-- his kitchen is actually fairly small. 02:45:05.420 --> 02:45:10.030 It is about the size of a small kitchen in Burton Conner, which 02:45:10.030 --> 02:45:11.630 is a dorm on campus. 02:45:11.630 --> 02:45:13.250 And you can see in the next slide 02:45:13.250 --> 02:45:16.980 that the stove is fairly close to the sink, 02:45:16.980 --> 02:45:24.020 and so it's a pretty small quarter for cooking. 02:45:24.020 --> 02:45:26.540 And he's looking for a way to improve 02:45:26.540 --> 02:45:27.945 the mobility in his kitchen. 02:45:31.010 --> 02:45:33.210 The assistive technology that Don uses 02:45:33.210 --> 02:45:37.310 includes Velcro, which is on the left hand side. 02:45:37.310 --> 02:45:39.710 He constantly tells us that Velcro is his friend, 02:45:39.710 --> 02:45:41.850 and he uses Velcro for his shoes. 02:45:41.850 --> 02:45:44.300 And on the far right side, he also 02:45:44.300 --> 02:45:46.490 uses a leg brace that prevents him 02:45:46.490 --> 02:45:48.380 from hyperextending his knee. 02:45:48.380 --> 02:45:51.330 But the most important assistive technology that he uses 02:45:51.330 --> 02:45:53.120 is in the center, his iPhone. 02:45:53.120 --> 02:45:55.350 So you can see, he's clearly really excited about it, 02:45:55.350 --> 02:45:59.170 and he's constantly using it to schedule tasks, to send emails, 02:45:59.170 --> 02:46:03.478 and he depends on this iPhone to remind him of his daily tasks. 02:46:08.750 --> 02:46:12.110 So in addition to those three items, 02:46:12.110 --> 02:46:14.040 he also uses a cane to help him walk. 02:46:14.040 --> 02:46:17.480 And so this is a quick video of him using his cane, 02:46:17.480 --> 02:46:20.430 and it's just simply to help him walk 02:46:20.430 --> 02:46:22.270 and to assist him in being mobile. 02:46:28.399 --> 02:46:29.940 JAN: So some challenges we've already 02:46:29.940 --> 02:46:32.590 seemed to have faced in this design 02:46:32.590 --> 02:46:34.820 project is our team scheduling. 02:46:34.820 --> 02:46:37.260 So it's really hard for us three to get together 02:46:37.260 --> 02:46:41.910 with Don at the same time, same place, and get something going. 02:46:41.910 --> 02:46:44.900 And with Don's cognitive overload, 02:46:44.900 --> 02:46:47.849 he also has issues focusing and telling us 02:46:47.849 --> 02:46:49.890 what he really wants for us to do on our project. 02:46:49.890 --> 02:46:53.070 So we initially started out with two projects 02:46:53.070 --> 02:46:56.140 that we were going to work for helping him with his cooking. 02:46:56.140 --> 02:46:58.700 As you can see here, we started off thinking of ways 02:46:58.700 --> 02:47:00.420 that we can help him out in the kitchen. 02:47:00.420 --> 02:47:02.470 So something that he did mention to us 02:47:02.470 --> 02:47:06.060 was the fact that he needs some help carrying big pots. 02:47:06.060 --> 02:47:08.540 So since he has one arm, it's really hard 02:47:08.540 --> 02:47:12.120 to actually stabilize the pot and move it from point A 02:47:12.120 --> 02:47:14.330 to point B without having the contents spill 02:47:14.330 --> 02:47:16.070 and move around too much. 02:47:16.070 --> 02:47:18.770 And another thing that was mentioned to us by-- oh, he's 02:47:18.770 --> 02:47:21.560 not here today-- another one of the actual participants 02:47:21.560 --> 02:47:24.000 of this class, Jeffrey, was something 02:47:24.000 --> 02:47:26.770 used for stirring or stabilizing the pot 02:47:26.770 --> 02:47:28.940 whenever he's either stirring or doing something 02:47:28.940 --> 02:47:30.560 with the contents of the pot. 02:47:30.560 --> 02:47:34.080 And we initially started off with two different projects 02:47:34.080 --> 02:47:36.370 that we were going to test out with Don 02:47:36.370 --> 02:47:39.340 and figure out what he really wanted out of us in this class. 02:47:39.340 --> 02:47:42.070 So the first one was the stability of the mixing pot 02:47:42.070 --> 02:47:45.120 or doing something with the pot or a bow. 02:47:45.120 --> 02:47:47.790 And we decided that we wanted to focus on these three 02:47:47.790 --> 02:47:50.970 little things, so minimizing how much the bowl moves, 02:47:50.970 --> 02:47:55.560 how much it tips over, and making sure that whatever 02:47:55.560 --> 02:47:58.830 we use is fast and easy to use. 02:47:58.830 --> 02:48:00.300 And as for moving pots, we wanted 02:48:00.300 --> 02:48:03.550 to focus more on how he can take these pots from point A 02:48:03.550 --> 02:48:07.420 to point B, so large pots with a lot of things inside of them, 02:48:07.420 --> 02:48:09.266 and minimize how much effort he has 02:48:09.266 --> 02:48:11.670 to put into moving these things and stabilizing them, 02:48:11.670 --> 02:48:14.530 while making it very easy to use as well 02:48:14.530 --> 02:48:18.720 and minimizing how much liquid falls off 02:48:18.720 --> 02:48:21.930 or how many things could go wrong with this. 02:48:21.930 --> 02:48:24.390 So we initially started off with some design prototypes 02:48:24.390 --> 02:48:29.575 for the stirring or for slipping is something that we called it. 02:48:29.575 --> 02:48:32.500 So we started for slipping, and we showed him 02:48:32.500 --> 02:48:35.450 some of these designs, and we got some very good feedback 02:48:35.450 --> 02:48:35.950 from him. 02:48:35.950 --> 02:48:39.040 He was very, very opposed to having something 02:48:39.040 --> 02:48:42.910 big and clunky in his desk or his workspace 02:48:42.910 --> 02:48:43.910 whenever he was cooking. 02:48:43.910 --> 02:48:47.464 And we used that to further our designs 02:48:47.464 --> 02:48:49.880 and make sure that we go with something smaller, something 02:48:49.880 --> 02:48:54.190 that doesn't get in the way and is very easy for him to use. 02:48:54.190 --> 02:48:56.300 And after that, we showed him some 02:48:56.300 --> 02:48:59.680 of the things that he may want to use for moving a pot. 02:48:59.680 --> 02:49:02.980 So over here, we can see something 02:49:02.980 --> 02:49:06.870 that can adjust to a pot and use some sort of strap 02:49:06.870 --> 02:49:09.620 around his forearm or shoulder to move the pot. 02:49:09.620 --> 02:49:13.040 Because he mentioned that he has some what we thought 02:49:13.040 --> 02:49:15.540 were really big pots to move around 02:49:15.540 --> 02:49:16.990 for a pretty long distance. 02:49:16.990 --> 02:49:19.073 This was before we actually went over to his house 02:49:19.073 --> 02:49:21.150 and found out what we were working with. 02:49:21.150 --> 02:49:24.120 And another thing that we thought was maybe-- he 02:49:24.120 --> 02:49:26.560 says he slides the pots a lot because it's a lot harder 02:49:26.560 --> 02:49:28.057 for him to carry them. 02:49:28.057 --> 02:49:29.640 Something that we thought of was maybe 02:49:29.640 --> 02:49:32.670 having a little mobile station for him to use, 02:49:32.670 --> 02:49:36.910 where he can slide the pot onto it, slide it across the floor, 02:49:36.910 --> 02:49:41.340 and then move it onto the actual stove itself. 02:49:41.340 --> 02:49:44.540 And finally, this is just some brainstorming/prototyping. 02:49:44.540 --> 02:49:48.780 We thought of like those things that drummers use, 02:49:48.780 --> 02:49:50.330 where they attach it to their chest, 02:49:50.330 --> 02:49:51.560 and you can pot in there. 02:49:51.560 --> 02:49:54.020 But this is just for brainstorming. 02:49:54.020 --> 02:49:55.780 We just threw ideas out there. 02:49:55.780 --> 02:49:57.430 And we showed these ideas to Don, 02:49:57.430 --> 02:50:00.130 and we decided that we were going 02:50:00.130 --> 02:50:05.190 to go much further into the actual movement of the pot, 02:50:05.190 --> 02:50:06.790 rather than the stirring, since he 02:50:06.790 --> 02:50:09.280 says that that's one of the big challenges that he has. 02:50:09.280 --> 02:50:11.917 And that's where we are currently at. 02:50:11.917 --> 02:50:14.000 We have identified the problem and know what we're 02:50:14.000 --> 02:50:17.500 going to do from here on out. 02:50:17.500 --> 02:50:19.130 CHRISTINA: So this past Friday we 02:50:19.130 --> 02:50:21.394 actually got to go to Don's apartment 02:50:21.394 --> 02:50:23.060 to actually see what his kitchen is like 02:50:23.060 --> 02:50:25.090 and what his cooking environment is like. 02:50:25.090 --> 02:50:27.900 And so before we were initially imagining 02:50:27.900 --> 02:50:30.229 that he was using pots that were like this big 02:50:30.229 --> 02:50:32.520 and that you would need to use like two hands to carry. 02:50:32.520 --> 02:50:35.210 But we actually found out that they're actually 02:50:35.210 --> 02:50:37.630 normal sized pots which you can carry with one hand, 02:50:37.630 --> 02:50:40.940 and also the thing about his kitchen space being very small 02:50:40.940 --> 02:50:46.141 made some of our initial designs not feasible. 02:50:46.141 --> 02:50:48.015 So here you can see a video of Don in action. 02:51:19.930 --> 02:51:21.740 So, as you can see, Don has trouble 02:51:21.740 --> 02:51:24.140 moving filled pots from his sink to his stove top 02:51:24.140 --> 02:51:26.056 without having some of the contents spill out. 02:51:28.510 --> 02:51:32.830 And so we kind of made a sketch of his kitchen layout. 02:51:32.830 --> 02:51:36.930 And so the task requirement that we decided on 02:51:36.930 --> 02:51:41.670 was that we wanted to help him be able to lift 02:51:41.670 --> 02:51:45.475 and move the filled pot and also not spill any of the contents. 02:51:48.130 --> 02:51:51.700 And so these are success metrics. 02:51:51.700 --> 02:51:55.460 Them metrics include lifting and moving the pot vertically 02:51:55.460 --> 02:51:58.616 as well as horizontally, and then the amount of spill there 02:51:58.616 --> 02:52:01.630 is , and also how much time it takes for him to move the pot 02:52:01.630 --> 02:52:03.640 from the sink to his stove top. 02:52:03.640 --> 02:52:10.400 And so we kind of evaluated the current state of how 02:52:10.400 --> 02:52:16.080 he accomplishes the task, and we used a scale from 1 to 10, 02:52:16.080 --> 02:52:18.730 one being we would really like to help 02:52:18.730 --> 02:52:23.120 him improve in this aspect, and 10 being this is OK, 02:52:23.120 --> 02:52:24.350 and this is great. 02:52:24.350 --> 02:52:30.877 So we have our current goals, or we have the current situation, 02:52:30.877 --> 02:52:31.835 and we have the target. 02:52:31.835 --> 02:52:33.293 And we also have our reached goals. 02:52:37.660 --> 02:52:40.310 So our contributions up to date-- 02:52:40.310 --> 02:52:44.180 since we haven't really gotten into the prototyping part yet, 02:52:44.180 --> 02:52:47.110 we have all been designing and brainstorming together. 02:52:47.110 --> 02:52:49.910 And so Jan has been facilitating the meetings. 02:52:49.910 --> 02:52:53.190 Eann has been documenting and taking notes, 02:52:53.190 --> 02:52:57.210 and I have been taking videos and also photos. 02:52:57.210 --> 02:52:59.790 And for our future contributions, 02:52:59.790 --> 02:53:02.920 we are going to continue doing what we're doing right now. 02:53:02.920 --> 02:53:07.660 Also, once we get a better idea of what are design will be, 02:53:07.660 --> 02:53:10.400 maybe split up the tasks for what 02:53:10.400 --> 02:53:12.224 different components of our product 02:53:12.224 --> 02:53:13.682 that we are going to be working on. 02:53:18.670 --> 02:53:22.660 So I guess like our most crucial step 02:53:22.660 --> 02:53:25.320 is our next step, which is like in the immediate future. 02:53:25.320 --> 02:53:27.820 So we really need to be able to come up 02:53:27.820 --> 02:53:30.836 with a design for our first prototype and get it to Don 02:53:30.836 --> 02:53:31.960 and get his feedback on it. 02:53:31.960 --> 02:53:35.950 So one of the main things that we will be focusing on 02:53:35.950 --> 02:53:39.050 for this first prototype will be mechanisms and concepts 02:53:39.050 --> 02:53:42.080 for how he can move a pot from a certain height 02:53:42.080 --> 02:53:45.220 to a higher place. 02:53:45.220 --> 02:53:47.320 And also, we might be considering the material 02:53:47.320 --> 02:53:50.120 that we will be using the product because that 02:53:50.120 --> 02:53:55.160 relates to, I guess, like how much mass he can move. 02:53:55.160 --> 02:53:59.260 And we will also be doing a more quantitative evaluation 02:53:59.260 --> 02:54:02.600 of Don's skills, so maybe like how much mass he can life, 02:54:02.600 --> 02:54:04.418 or how long can he hold up a pot for. 02:54:10.280 --> 02:54:14.520 And so I these are our project plans. 02:54:14.520 --> 02:54:17.440 So, as I mentioned before, our main thing right now 02:54:17.440 --> 02:54:20.200 is to get our first prototype out and get his feedback on it. 02:54:20.200 --> 02:54:23.170 And then from then on, we can add more details 02:54:23.170 --> 02:54:26.578 into our planning for how we are going to finish this product. 02:54:35.061 --> 02:54:37.347 PROFESSOR 5: Any questions? 02:54:37.347 --> 02:54:38.055 Great, thank you. 02:54:43.070 --> 02:54:45.500 PROFESSOR 6: Did he articulate any other scenarios 02:54:45.500 --> 02:54:49.340 of where her would move the pot, aside from stove to sink? 02:54:52.134 --> 02:54:53.800 JAN: No, that's the only one we actually 02:54:53.800 --> 02:54:55.700 saw him doing physically. 02:54:55.700 --> 02:54:59.790 But I imagine that he would have to potentially move something 02:54:59.790 --> 02:55:02.400 that has like maybe spaghetti to cool it down somewhere else 02:55:02.400 --> 02:55:06.970 and maybe actually serving my the pot, so from his 02:55:06.970 --> 02:55:07.967 to the kitchen table. 02:55:07.967 --> 02:55:10.050 But that's the only one we actually saw him doing, 02:55:10.050 --> 02:55:12.870 and that's why we are going to get some further tests to see 02:55:12.870 --> 02:55:15.530 distance, weight, and other things that could potentially 02:55:15.530 --> 02:55:16.750 play into our design. 02:55:16.750 --> 02:55:18.250 PROFESSOR 6: So I was wondering that 02:55:18.250 --> 02:55:21.030 about how that may impact your metrics 02:55:21.030 --> 02:55:24.430 or quantitative metrics of being able to move it three feet. 02:55:24.430 --> 02:55:26.130 AUDIENCE: Maybe you want to try to try 02:55:26.130 --> 02:55:29.945 to get him to fill the pot and move it 02:55:29.945 --> 02:55:33.780 while there's hot liquid because that may make a big difference. 02:55:33.780 --> 02:55:36.850 And he was very aloof about splashing cold water, 02:55:36.850 --> 02:55:39.337 but he might not want to do that with boiling water. 02:55:39.337 --> 02:55:41.420 JAN: No, we didn't want anybody to get hurt there. 02:55:44.407 --> 02:55:46.365 AUDIENCE: Did you guys try the pot-moving thing 02:55:46.365 --> 02:55:50.709 yourselves to see how much-- you filled 02:55:50.709 --> 02:55:52.000 the pot all the way to the top. 02:55:52.000 --> 02:55:55.920 How feasible is it for like one of you to do that? 02:55:55.920 --> 02:55:56.900 JAN: No, we did not. 02:55:56.900 --> 02:55:57.976 It's something that we should have done. 02:55:57.976 --> 02:55:58.790 You're right. 02:56:03.549 --> 02:56:05.840 PROFESSOR 5: So imagine everything goes amazingly well. 02:56:05.840 --> 02:56:07.212 What will you actually make? 02:56:07.212 --> 02:56:08.384 What will you actually do? 02:56:08.384 --> 02:56:09.550 Will it be a redesigned pot? 02:56:09.550 --> 02:56:12.530 Is it sort of like thinking about the procedure 02:56:12.530 --> 02:56:15.010 of how to do these tasks? 02:56:15.010 --> 02:56:17.670 You can imagine building a robot that could do it. 02:56:17.670 --> 02:56:20.564 It would be like really hard. 02:56:20.564 --> 02:56:21.980 What are you actually going to do? 02:56:21.980 --> 02:56:24.130 JAN: So what really thought was an attachment 02:56:24.130 --> 02:56:27.620 that you can adjust to almost any type of pot. 02:56:27.620 --> 02:56:29.530 So one that I showed over there was something 02:56:29.530 --> 02:56:32.050 that you can put around the top side of the pot, 02:56:32.050 --> 02:56:36.960 so a belt or some type of thing, where 02:56:36.960 --> 02:56:38.480 it hooks on to the top of the pot, 02:56:38.480 --> 02:56:42.630 and you have belt on top of it, where he can-- 02:56:42.630 --> 02:56:45.110 he says he would really like to be able to really use 02:56:45.110 --> 02:56:47.650 his forearm because his fingers also get really tired, to be 02:56:47.650 --> 02:56:52.320 able to put the belt over his arm and then carry it over, 02:56:52.320 --> 02:56:53.923 using that, rather than the handle, 02:56:53.923 --> 02:56:55.589 where he doesn't have as much stability. 02:56:58.971 --> 02:57:01.220 PROFESSOR 1: I do want to echo what was said over here 02:57:01.220 --> 02:57:02.460 about heat. 02:57:02.460 --> 02:57:04.650 I think that the fact that you didn't mentioned 02:57:04.650 --> 02:57:07.890 that at all in your success metrics or in your constraints 02:57:07.890 --> 02:57:10.060 is actually a pretty serious problem, right? 02:57:10.060 --> 02:57:14.070 He's moving a pot to his sink-- I'm sorry to the stove 02:57:14.070 --> 02:57:16.302 in order to heat it up. 02:57:16.302 --> 02:57:18.510 And then if he's going to continue to be independent, 02:57:18.510 --> 02:57:19.926 he's going to have to do something 02:57:19.926 --> 02:57:23.270 with that hot, still heavy pot. 02:57:23.270 --> 02:57:26.372 So you need a consideration here which is 02:57:26.372 --> 02:57:27.580 that he doesn't burn himself. 02:57:30.410 --> 02:57:32.810 And I think that spillage may be something 02:57:32.810 --> 02:57:36.300 that you should give a little less concern to because that 02:57:36.300 --> 02:57:40.182 can be solved by not filling it up as much because that would 02:57:40.182 --> 02:57:42.682 boil over anyway, if you filled it up as much as he actually 02:57:42.682 --> 02:57:46.370 did in that video or by putting lids on it. 02:57:46.370 --> 02:57:48.690 But I really would encourage you to worry much more 02:57:48.690 --> 02:57:52.549 and pay much more attention to the problem of heat. 02:57:52.549 --> 02:57:54.340 JAN: That's something that we'll definitely 02:57:54.340 --> 02:57:54.770 take into account then. 02:57:54.770 --> 02:57:56.270 AUDIENCE: Especially if you're going 02:57:56.270 --> 02:57:58.450 in the direction of putting something 02:57:58.450 --> 02:58:01.430 that's close to his body. 02:58:01.430 --> 02:58:05.730 And you can do tests with him not burning him, 02:58:05.730 --> 02:58:07.251 like put food coloring. 02:58:07.251 --> 02:58:09.500 Have him wear something he doesn't care about, and see 02:58:09.500 --> 02:58:12.650 if he an immediate reflex if he's spilling food coloring 02:58:12.650 --> 02:58:13.440 on his clothes. 02:58:13.440 --> 02:58:16.650 It'll give you a better sense of is he really 02:58:16.650 --> 02:58:19.600 that confident with this forearm, for instance. 02:58:19.600 --> 02:58:21.740 PROFESSOR 5: So it's a really hard problem. 02:58:21.740 --> 02:58:23.890 In some ways, I'll just be honest, 02:58:23.890 --> 02:58:26.760 like when I first saw this compelling client, 02:58:26.760 --> 02:58:30.210 and it's like, this is a great person. 02:58:30.210 --> 02:58:32.290 It would be great to help him, and I 02:58:32.290 --> 02:58:33.770 know that he loves to cook. 02:58:33.770 --> 02:58:38.770 But dealing with pots full of water, possibly hot water, 02:58:38.770 --> 02:58:40.710 that just seems like a really hard problem. 02:58:40.710 --> 02:58:42.890 And I wonder if there's something else 02:58:42.890 --> 02:58:47.250 you can do for him that's not so physically, like something 02:58:47.250 --> 02:58:49.791 that doesn't have a safety dimension. 02:58:49.791 --> 02:58:51.290 You don't want to give him something 02:58:51.290 --> 02:58:53.331 he's going to burn himself with badly on his own. 02:58:53.331 --> 02:58:54.909 You know what I mean? 02:58:54.909 --> 02:58:57.200 JAN: Yeah, we could also take the alternative approach, 02:58:57.200 --> 02:59:00.794 the actual stirring or moving the things within the pot. 02:59:00.794 --> 02:59:02.210 PROFESSOR 5: Or maybe he just lets 02:59:02.210 --> 02:59:03.600 it cool for a really long time. 02:59:03.600 --> 02:59:05.010 But how do you get the food out? 02:59:05.010 --> 02:59:05.460 I don't know. 02:59:05.460 --> 02:59:07.584 Maybe there's a way to rethink the entire-- I mean, 02:59:07.584 --> 02:59:09.540 the goal is to have cooked food. 02:59:09.540 --> 02:59:11.870 Is there a way to rethink how you get cooked food 02:59:11.870 --> 02:59:13.747 at the end of the day that avoids lifting 02:59:13.747 --> 02:59:14.830 a heavy pot from the sink. 02:59:14.830 --> 02:59:16.372 AUDIENCE: Have a longer hose. 02:59:16.372 --> 02:59:18.580 AUDIENCE: That's another way to do the filling right? 02:59:18.580 --> 02:59:19.536 PROFESSOR 5: You can imagine filling it 02:59:19.536 --> 02:59:21.240 with like small-- you know, a ferry 02:59:21.240 --> 02:59:22.706 system of smaller things that get 02:59:22.706 --> 02:59:23.914 added a little bit at a time. 02:59:23.914 --> 02:59:25.000 AUDIENCE: Or an interesting pump [INAUDIBLE]. 02:59:25.000 --> 02:59:27.542 PROFESSOR 5: If you can sort of train him how to do the task. 02:59:27.542 --> 02:59:29.166 I wonder if there are experts out there 02:59:29.166 --> 02:59:31.090 in the world that figure out how to do this. 02:59:31.090 --> 02:59:33.700 Disabled cooking, is there such a thing? 02:59:33.700 --> 02:59:35.196 But I admire you for taking it on. 02:59:35.196 --> 02:59:38.351 It just seems really hard and dangerous. 02:59:38.351 --> 02:59:40.017 PROFESSOR 4: Great, thank you, Team Don. 02:59:40.017 --> 02:59:40.558 Thanks again. 02:59:44.490 --> 02:59:46.814 We managed to get through them all. 02:59:46.814 --> 02:59:48.480 We have maybe two or three minutes left. 02:59:48.480 --> 02:59:51.710 Maybe I'll ask if the panelists or the support staff 02:59:51.710 --> 02:59:55.600 have general comments on all the presentation today, 02:59:55.600 --> 02:59:56.910 for the panelists here today. 02:59:56.910 --> 02:59:59.800 And Professor Miller, if you have general comments or advice 02:59:59.800 --> 03:00:03.490 on the presentations or the project progress in general, 03:00:03.490 --> 03:00:04.990 give you the opportunity to do that. 03:00:07.350 --> 03:00:10.580 But while you think about that, just one reminder 03:00:10.580 --> 03:00:13.810 is to remember to upload your slides from the presentation 03:00:13.810 --> 03:00:20.132 today, so that we can integrate these things into the video, 03:00:20.132 --> 03:00:22.090 and so that we can look at your slides as well. 03:00:22.090 --> 03:00:23.940 And then the reports are due Friday, 03:00:23.940 --> 03:00:27.160 and then next week, we'll have read all the reports, 03:00:27.160 --> 03:00:30.470 and we'll give you some more written feedback, a letter 03:00:30.470 --> 03:00:34.140 grade at this point in time. 03:00:34.140 --> 03:00:36.141 But I'll of the panelists, Jose or Anna, 03:00:36.141 --> 03:00:37.640 Professor Leonard, Professor Miller, 03:00:37.640 --> 03:00:41.670 if you have any general comments or advice for teams 03:00:41.670 --> 03:00:43.444 at this point in time. 03:00:43.444 --> 03:00:45.860 PROFESSOR 1: Great to see the progress that you're making. 03:00:45.860 --> 03:00:48.920 Keep meeting with your clients, and focus 03:00:48.920 --> 03:00:51.630 on trying to finish that prototype that you're 03:00:51.630 --> 03:00:53.824 going to deliver at the end of the semester. 03:00:53.824 --> 03:00:55.490 PROFESSOR 5: I would just say, like I've 03:00:55.490 --> 03:00:57.590 taught design classes and mechanical and ocean 03:00:57.590 --> 03:01:00.480 engineering, and it's really challenging 03:01:00.480 --> 03:01:03.720 when the schedule crunch at the end of the semester, 03:01:03.720 --> 03:01:05.670 and so sometimes you're going to have 03:01:05.670 --> 03:01:07.240 to down scope towards the end. 03:01:07.240 --> 03:01:10.279 But if you try to really think about a measurable result, 03:01:10.279 --> 03:01:11.820 that you really accomplish something, 03:01:11.820 --> 03:01:14.490 and what that would be, and make sure you at least get that far. 03:01:14.490 --> 03:01:17.840 Like it would be a disaster if you didn't at least do x. 03:01:17.840 --> 03:01:18.730 What is x? 03:01:18.730 --> 03:01:22.817 Have a prototype that does something, that gives 03:01:22.817 --> 03:01:23.900 some value to your client. 03:01:23.900 --> 03:01:26.510 And so the time's going to go really quickly, 03:01:26.510 --> 03:01:30.125 and you're going to run out of time. 03:01:30.125 --> 03:01:32.250 PROFESSOR 6: I would say it's great to that you all 03:01:32.250 --> 03:01:34.660 are meeting what seems like a regular basis 03:01:34.660 --> 03:01:37.700 with your collaborators for these projects. 03:01:37.700 --> 03:01:39.200 And so take advantage of every time 03:01:39.200 --> 03:01:41.390 you're meeting with them to bring something 03:01:41.390 --> 03:01:44.210 you can hold in your hand that is going to impact 03:01:44.210 --> 03:01:46.570 the final design, whether a potential material 03:01:46.570 --> 03:01:49.960 you could use, a prototype of a looks-like design, 03:01:49.960 --> 03:01:51.420 or this is a feature design. 03:01:51.420 --> 03:01:53.430 But that'll really help you to continue 03:01:53.430 --> 03:01:54.920 to iterate on those features. 03:01:58.250 --> 03:02:01.520 AUDIENCE: I would echo Professor Leonard's comments 03:02:01.520 --> 03:02:03.120 of take something. 03:02:03.120 --> 03:02:06.820 If you're going towards the end of the semester, 03:02:06.820 --> 03:02:08.736 pick that one item that you know is going 03:02:08.736 --> 03:02:11.300 to make a critical difference. 03:02:11.300 --> 03:02:15.330 If you spend too much time picking pots, 03:02:15.330 --> 03:02:18.250 we know what pots look like, and how they behave. 03:02:18.250 --> 03:02:21.390 But if you don't know how another mechanism that you're 03:02:21.390 --> 03:02:23.720 designing behaves, then focus on that one. 03:02:23.720 --> 03:02:27.660 And just in case you do run out of time, 03:02:27.660 --> 03:02:31.170 you know that that's an addressable thing to leave out. 03:02:31.170 --> 03:02:33.780 Don't leave out the [? core ?] [INAUDIBLE]. 03:02:33.780 --> 03:02:35.530 PROFESSOR 4: Michelle, [INAUDIBLE], Grace, 03:02:35.530 --> 03:02:37.140 you have general comments? 03:02:39.720 --> 03:02:40.640 OK, cool. 03:02:40.640 --> 03:02:42.930 I think one thing I'll say is I think you all 03:02:42.930 --> 03:02:45.420 have gotten to know your clients really well, 03:02:45.420 --> 03:02:47.550 from the presentations. 03:02:47.550 --> 03:02:51.330 On Monday and Wednesday and on Friday night or on the weekend, 03:02:51.330 --> 03:02:54.870 Grace and I watched all the videos that where submitted. 03:02:54.870 --> 03:02:57.040 We're all very impressed. 03:02:57.040 --> 03:02:58.750 You really have spent a lot of time 03:02:58.750 --> 03:03:00.820 and really gotten to know the people. 03:03:00.820 --> 03:03:02.587 One thing I would suggest is you really, 03:03:02.587 --> 03:03:04.670 maybe in the next couple weeks, really, really get 03:03:04.670 --> 03:03:06.900 to know the client's task. 03:03:06.900 --> 03:03:08.910 I mean really break it down and come up 03:03:08.910 --> 03:03:12.130 with these measurable metrics, try things out, 03:03:12.130 --> 03:03:15.630 food color the water, things like that, so you can really 03:03:15.630 --> 03:03:17.300 get a sense of whether your device 03:03:17.300 --> 03:03:20.925 or whether the system you're building is going to work. 03:03:20.925 --> 03:03:23.230 PROFESSOR 5: Like really put yourself in their shoes. 03:03:23.230 --> 03:03:25.370 PROFESSOR 4: OK, I think that's pretty much it. 03:03:25.370 --> 03:03:27.880 Next week we're going to do a bunch of electronic device 03:03:27.880 --> 03:03:29.850 labs, so bring your laptop computer 03:03:29.850 --> 03:03:31.750 is what we're hoping for people to bring. 03:03:31.750 --> 03:03:33.291 Grace, you have a final announcement? 03:03:33.291 --> 03:03:35.660 GRACE: Yeah, we sent out a poll today. 03:03:35.660 --> 03:03:39.170 We're going to set up twice weekly hobby shop office hours. 03:03:39.170 --> 03:03:42.720 So if you think you're going to be using a hobby shop 03:03:42.720 --> 03:03:45.520 or building anything mechanical, please fill out the-- we'll 03:03:45.520 --> 03:03:47.395 decide by Friday what those office hours are. 03:03:47.395 --> 03:03:47.670 Thanks. 03:03:47.670 --> 03:03:49.295 PROFESSOR 4: And Monday's class lecture 03:03:49.295 --> 03:03:51.070 and lab will both be in this room 03:03:51.070 --> 03:03:53.350 because we're doing these electronic device access 03:03:53.350 --> 03:03:58.150 labs, so 32044 at both 1:00 PM and 3:00 PM. 03:03:58.150 --> 03:03:59.700 OK, thanks.
