1
00:00:16,440 --> 00:00:17,620
JANE: Hi, everyone.

2
00:00:17,620 --> 00:00:19,930
So our project is
called Mini Worlds.

3
00:00:19,930 --> 00:00:22,490
So basically, we want
to view this video game

4
00:00:22,490 --> 00:00:27,420
where you can build your world
with Kinect by just grabbing

5
00:00:27,420 --> 00:00:30,120
things and build them
by dropping them.

6
00:00:30,120 --> 00:00:34,350
So the idea is you can go
into this 3-D environment

7
00:00:34,350 --> 00:00:38,140
to design your own
home and your own room.

8
00:00:38,140 --> 00:00:39,930
So my name is Jane.

9
00:00:39,930 --> 00:00:44,010
So I'm from Course 3 and
I'm a graduate student.

10
00:00:44,010 --> 00:00:47,770
CATTLEYA: I am Cattleya, I am
Course 6 undergrad student,

11
00:00:47,770 --> 00:00:50,130
class of 2019.

12
00:00:50,130 --> 00:00:53,730
So we address this
problem of when

13
00:00:53,730 --> 00:00:58,950
we try to create our own world,
as Jane has already introduced.

14
00:00:58,950 --> 00:01:04,650
So we then come up with a
word game called Media World.

15
00:01:04,650 --> 00:01:07,910
And we will show
you our demo now.

16
00:01:11,990 --> 00:01:19,000
[SIDE CONVERSATION]

17
00:01:19,000 --> 00:01:21,970
JANE: So Cattleya will
be controlling the game

18
00:01:21,970 --> 00:01:23,850
and I will be doing here.

19
00:01:32,750 --> 00:01:34,434
[SIDE CONVERSATION]

20
00:02:04,027 --> 00:02:05,610
JANE: So I hope it's
not capturing me.

21
00:02:10,747 --> 00:02:12,700
PROFESSOR: You may
want to restart.

22
00:02:12,700 --> 00:02:15,122
JANE: Yeah, we will restart.

23
00:02:15,122 --> 00:02:17,512
PROFESSOR: There's going to
be technical difficulties.

24
00:02:20,140 --> 00:02:22,910
One of the [INAUDIBLE]
presentation [INAUDIBLE]..

25
00:02:22,910 --> 00:02:24,700
JANE: OK.

26
00:02:24,700 --> 00:02:28,490
So now we are trying to
locate ourself in our home.

27
00:02:31,382 --> 00:02:32,828
PROFESSOR: Move a little closer.

28
00:02:39,580 --> 00:02:42,657
JANE: Could it be it is
capturing other people?

29
00:02:42,657 --> 00:02:44,490
MARK VRABLIC: I mean
you can check for this.

30
00:02:44,490 --> 00:02:45,406
CATTLEYA: Yeah, maybe.

31
00:02:45,406 --> 00:02:46,990
I think so.

32
00:02:46,990 --> 00:02:47,990
It's [INAUDIBLE]

33
00:02:47,990 --> 00:02:51,011
JANE: Yeah, I think
it's not tracking her.

34
00:02:51,011 --> 00:02:51,510
So--

35
00:02:56,527 --> 00:02:58,110
STUDENT: Do you have
the [INAUDIBLE]??

36
00:02:58,110 --> 00:02:58,610
JANE: Yes.

37
00:02:58,610 --> 00:03:01,730
MARK VRABLIC: You
should pull that out.

38
00:03:01,730 --> 00:03:03,090
I don't know how [INAUDIBLE]

39
00:03:03,090 --> 00:03:12,610
[SIDE CONVERSATION]

40
00:03:52,331 --> 00:03:52,830
JANE: OK.

41
00:03:52,830 --> 00:03:55,480
So somehow, we just got indoor.

42
00:03:55,480 --> 00:03:58,020
Because we saw a house and we
just went through that door

43
00:03:58,020 --> 00:04:00,000
to go into your room.

44
00:04:00,000 --> 00:04:03,430
And your getting all
of you to your yard.

45
00:04:18,120 --> 00:04:20,359
PROFESSOR: So how are
you switching rooms?

46
00:04:20,359 --> 00:04:22,089
CATTLEYA: We changed the scene.

47
00:04:22,089 --> 00:04:24,199
We can disable it right now.

48
00:04:24,199 --> 00:04:25,115
PROFESSOR: [INAUDIBLE]

49
00:04:25,115 --> 00:04:26,323
CATTLEYA: To a wider problem.

50
00:04:31,474 --> 00:04:32,458
[INAUDIBLE]

51
00:04:55,080 --> 00:04:58,580
JANE: So what we just did is
that we deleted that door.

52
00:04:58,580 --> 00:05:01,640
So cannot go indoor and now
you can travel more freely

53
00:05:01,640 --> 00:05:04,915
in your yard, not
through just that door.

54
00:05:06,815 --> 00:05:11,280
CATTLEYA: We tried to
really show you the thing,

55
00:05:11,280 --> 00:05:12,765
how to like--

56
00:05:12,765 --> 00:05:15,982
we can choose the material
and then choose the object

57
00:05:15,982 --> 00:05:18,705
to paint into [INAUDIBLE].

58
00:05:26,625 --> 00:05:28,605
Then you can [INAUDIBLE].

59
00:05:34,050 --> 00:05:35,040
Oh, sorry.

60
00:05:37,515 --> 00:05:42,465
[INAUDIBLE] low
position if you delete.

61
00:05:42,465 --> 00:05:49,395
So that we-- here, you
will see [INAUDIBLE] oh.

62
00:05:49,395 --> 00:05:53,355
We can also rotate thing
around, I can show you.

63
00:06:09,310 --> 00:06:10,940
JANE: So the only
problem here is

64
00:06:10,940 --> 00:06:13,150
it's a little bit hard
to control things.

65
00:06:15,720 --> 00:06:17,112
But we will get there.

66
00:06:17,112 --> 00:06:18,600
[APPLAUSE]

67
00:06:23,064 --> 00:06:27,640
CATTLEYA: Let me show you.

68
00:06:27,640 --> 00:06:33,270
Now, we will get rid of
all the stuff we have build

69
00:06:33,270 --> 00:06:36,970
and we will try to build
from the scratch for you.

70
00:06:40,970 --> 00:06:50,046
[SIDE CONVERSATION]

71
00:06:50,046 --> 00:06:53,490
JANE: So we just
deleted the yard

72
00:06:53,490 --> 00:06:56,880
and you want to
locate yourself again.

73
00:07:03,642 --> 00:07:07,600
No-- oh, yeah.

74
00:07:07,600 --> 00:07:08,500
Here.

75
00:07:08,500 --> 00:07:09,232
Good.

76
00:07:09,232 --> 00:07:13,168
CATTLEYA: Now, we have
to grab some object here.

77
00:07:13,168 --> 00:07:14,160
And then--

78
00:07:14,160 --> 00:07:18,290
JANE: And you can
create that object.

79
00:07:18,290 --> 00:07:21,042
CATTLEYA: And then you can
create it by raising your hand.

80
00:07:21,042 --> 00:07:22,008
AUDIENCE: What?

81
00:07:22,008 --> 00:07:22,974
[LAUGHTER]

82
00:07:27,321 --> 00:07:32,880
You can delete it by
lower your hand down.

83
00:07:32,880 --> 00:07:36,425
Also, now I will try
to do the rotation.

84
00:07:47,220 --> 00:07:49,424
[SIDE CONVERSATION]

85
00:07:49,424 --> 00:07:52,292
[INAUDIBLE]

86
00:07:52,292 --> 00:07:54,444
JANE: I think that's fine.

87
00:07:54,444 --> 00:07:57,610
PROFESSOR: This is an
operation [INADUCIBLE]..

88
00:07:57,610 --> 00:07:58,130
JANE: OK.

89
00:07:58,130 --> 00:07:58,671
CATTLEYA: OK.

90
00:07:58,671 --> 00:08:00,872
So now, you can create a bridge.

91
00:08:00,872 --> 00:08:06,078
And you can grab it and
rotate it around like this.

92
00:08:06,078 --> 00:08:08,054
[APPLAUSE]

93
00:08:13,982 --> 00:08:19,416

00:08:19,416 --> 00:08:25,344
[APPLAUSE]

95
00:08:25,344 --> 00:08:28,300
CATTLEYA: Another thing that you
can control this, the camera.

96
00:08:28,300 --> 00:08:34,250
If you wanted to, maybe you
can do something like this or--

97
00:08:34,250 --> 00:08:35,429
and so now like this.

98
00:08:39,221 --> 00:08:41,549
Also, if you want
to rotate a camera,

99
00:08:41,549 --> 00:08:45,533
you can [INAUDIBLE]
move body like this.

100
00:08:45,533 --> 00:08:48,521

PROFESSOR: Awesome.

103
00:09:04,457 --> 00:09:06,947
Do we have any questions?

104
00:09:06,947 --> 00:09:08,441
AUDIENCE: How are
you so amazing?

105
00:09:08,441 --> 00:09:09,757

106
00:09:09,757 --> 00:09:10,590
CATTLEYA: Thank you.

107
00:09:13,130 --> 00:09:14,980
AUDIENCE: What were the--

108
00:09:14,980 --> 00:09:17,696
what's the role did
you use to establish

109
00:09:17,696 --> 00:09:20,830
what kind of protocols?

110
00:09:20,830 --> 00:09:27,132
Were there some kind
of preformatted roles

111
00:09:27,132 --> 00:09:31,111
that connect, or did you
all just do that scratch?

112
00:09:31,111 --> 00:09:31,610
JANE: Oh.

113
00:09:31,610 --> 00:09:36,890
So for the Kinect,
our TA have already

114
00:09:36,890 --> 00:09:39,920
made the script that
allow us to keep track

115
00:09:39,920 --> 00:09:43,640
of the coordinate
in 3D of our hands

116
00:09:43,640 --> 00:09:46,040
and the other joints like hips.

117
00:09:46,040 --> 00:09:48,540
And what I do is that we--

118
00:09:48,540 --> 00:09:51,740
I implement-- For example,
the zoom in and zoom out.

119
00:09:51,740 --> 00:09:58,370
I implement that if
your right hand is

120
00:09:58,370 --> 00:10:02,660
behind your right shoulder
for a certain amount,

121
00:10:02,660 --> 00:10:04,040
you will got zoom out.

122
00:10:04,040 --> 00:10:06,830
And if it--

123
00:10:06,830 --> 00:10:11,000
I think it's the C
direction, C index.

124
00:10:11,000 --> 00:10:13,850
If it more than
your shoulder, it

125
00:10:13,850 --> 00:10:17,947
will go to zoom in like that.

126
00:10:17,947 --> 00:10:20,155
PROFESSOR: So they build a
lot of their own intervals

127
00:10:20,155 --> 00:10:23,104
based on x and y
and z coordinates.

128
00:10:23,104 --> 00:10:25,423
So any gesture that
she was doing she

129
00:10:25,423 --> 00:10:28,725
actually programmed just
based on plain logical rules

130
00:10:28,725 --> 00:10:32,340
about where two
points in space are.

131
00:10:32,340 --> 00:10:35,378
MARK VRABLIC: So you
train it beforehand.

132
00:10:35,378 --> 00:10:38,045
And then I'm curious whether
if you had another Kinect,

133
00:10:38,045 --> 00:10:40,091
it'd be more
responsive if you had

134
00:10:40,091 --> 00:10:41,385
one in the front and the back.

135
00:10:41,385 --> 00:10:45,172
That really makes the sensors
twenty one mega sense.

136
00:10:48,550 --> 00:10:49,900
[SIDE CONVERSATION]

137
00:10:50,749 --> 00:10:52,874
MARK VRABLIC: That's going
to be hard to implement,

138
00:10:52,874 --> 00:10:54,665
but yes, theoretically,
it would be better.

139
00:10:54,665 --> 00:10:56,870
People do do it.

140
00:10:56,870 --> 00:11:00,276
It'd be a lot of math to
get the two to match up.

141
00:11:00,276 --> 00:11:02,838
Also, there are [INAUDIBLE]
camera who probably started

142
00:11:02,838 --> 00:11:03,252
to render at each other.

143
00:11:03,252 --> 00:11:03,752
Okay.

144
00:11:08,445 --> 00:11:09,070
JANE: Question?

145
00:11:09,070 --> 00:11:11,950
AUDIENCE: Have you had Unity
experience before this class?

146
00:11:11,950 --> 00:11:14,560
JANE: I have a little bit.

147
00:11:14,560 --> 00:11:18,780
But yes, but learn
from this class a lot.

148
00:11:18,780 --> 00:11:20,076
Yes.

149
00:11:20,076 --> 00:11:22,030

150
00:11:22,030 --> 00:11:23,640
JANE: No, it never happened.

00:11:23,640 --> 00:11:24,140
Yes.

00:11:30,240 --> 00:11:30,740
All right.
