01:03
Now, I am going to ask you a real simple question about Google Glass:
22
63620
2618
ืขื›ืฉื™ื•, ืื ื™ ืืฉืืœ ืืชื›ื ืฉืืœื” ืืžื™ืชื™ืช ื•ืคืฉื•ื˜ื” ืขืœ ืžืฉืงืคื™ ื’ื•ื’ืœ:
01:06
how would you prototype this experience?
23

ืื™ืš ื”ื™ื™ืชื ื™ื•ืฆืจื™ื ืื‘ ื˜ื™ืคื•ืก ืฉืœ ื”ื—ื•ื•ื™ื” ื”ื–ื•?
01:08
How long do you think it would take you
24
68245
1457
ื›ืžื” ื–ืžืŸ ืืชื ื—ื•ืฉื‘ื™ื ื”ื™ื” ืœื•ืงื— ืœื›ื
01:09
to make the first working version of the headset display?
25

ืœื™ืฆื•ืจ ืืช ื”ื’ืจืกื” ื”ืขื•ื‘ื“ืช ื”ืจืืฉื•ื ื” ืฉืœ ื”ืชืฆื•ื’ื” ื”ืขื™ืœื™ืช?
01:17
Okay, a little bit on the long side.
26
77428
1918
ืื•ืงื™ื™, ื“ื™ ื”ืจื‘ื”.
01:19
The answer is one day.
27
79346
3073
ื”ืชืฉื•ื‘ื” ื”ื™ื ื™ื•ื ืื—ื“.
01:22
And here's what it looked like.
28
82419
1130
ื•ื”ื ื” ืื™ืš ืฉื–ื” ื ืจืื”.
01:23
So, basically the magic piece is the coat hanger.
29
83549
3925
ืื–, ื‘ืขื™ืงืจื•ืŸ ื”ื—ืœืง ื”ืงืกื•ื ื”ื•ื ืžืชืœื” ื”ืžืขื™ืœื™ื ื”ื–ื”.
01:27
The coat hanger, I bent it in a specific shape
30
87474
2437
ืžืชืœื” ื”ืžืขื™ืœื™ื, ื›ื•ืคืคืชื™ ืื•ืชื• ื‘ืฆื•ืจื” ืžืกื•ื™ื™ืžืช
01:29
and the top loop goes around your neck
31
89911
1666
ื•ื”ืœื•ืœืื” ื”ืขืœื™ื•ื ื” ื”ื•ืœื›ืช ืžืกื‘ื™ื‘ ืœืฆื•ื•ืืจ
01:31
and then the bottom loop rests against your chest
32
91577
2925
ื•ืื– ื”ืœื•ืœืื” ื”ืชื—ืชื•ื ื” ื ื—ื” ืขืœ ื”ื—ื–ื” ืฉืœื›ื
01:34
and it allows me to carry a piece of plexiglass
33
94502
3303
ื•ืžืืคืฉืจืช ืœื™ ืœืฉืืช ืืช ืคื™ืกืช ื”ืคืจืกืคืงืก ื”ื–ื•
01:37
on with a little sheet protector.
34
97805
1394
ื™ื—ื“ ืขื ื™ืจื™ืขืช ื”ื’ื ื”.
01:39
So these are the things you put your book reports in
35
99199
2304
ืื– ืืœื” ื”ื“ื‘ืจื™ื ืขืœื™ื”ื ืืชื ืฉืžื™ื ืืช ืกื™ื›ื•ื ื”ืกื™ืคื•ืจ ื‘ืชื•ื›ื
01:41
so they don't get wet,
36
101503
1072
ื›ืš ืฉื”ื ืœื ื™ืจื˜ื‘ื•,
01:42
I literally got at the drug store.
37
102575
1582
ืฉื”ืฉื’ืชื™ ืžื™ืœื•ืœื™ืช ื‘ื—ื ื•ืช ื”ื›ืœ ื‘ื•.
01:44
You know, have it out at the end of the plexiglass
38
104157
2527
ืืชื ื™ื•ื“ืขื™ื, ืœืฉื™ื ืืช ื–ื” ื‘ืงืฆื” ื”ืคืจืกืคืงืก
01:46
and then it gets projected onto with the pico projector
39
106684
2248
ื•ืื– ื–ื” ืžื•ืงืจืŸ ืขืœื™ื• ืขื ืคื™ืงื• ืžืงืจืŸ
01:48
that's connected to a Netbook.
40
108932
2264
ืฉืžื—ื•ื‘ืจ ืœืžื—ืฉื‘ ืจืฉืช.
01:51
And using this set-up, within one day
41
111196
1727
ื•ืขื ื”ืžืชืงืŸ ื”ื–ื”, ืชื•ืš ื™ื•ื
01:52
we're already able to start having the experience
42
112923
2338
ื›ื‘ืจ ื”ื™ื™ื ื• ืžืกื•ื’ืœื™ื ืœืงื‘ืœ ืืช ื”ื—ื•ื•ื™ื”
01:55
of what it looks like to have digital things
43
115261
2494
ืฉืœ ืื™ืš ื–ื” ื ืจืื” ืฉื™ื”ื™ื• ื“ื‘ืจื™ื ื“ื™ื’ื™ื˜ืœื™ื™ื
01:57
overlaid on your physical world,
44
117755
1731
ืžืจื•ื‘ื“ื™ื ืขืœ ื”ืขื•ืœื ื”ืคื™ืกื™ ืฉืœื›ื,
01:59
be able to move around with it,
45
119486
1597
ืœื”ื™ื•ืช ืžืกื•ื’ืœื™ื ืœื ื•ืข ืขื ื–ื”,
02:01
and also use the Netbook to try out
46
121083
1957
ื•ื’ื ืœื”ืฉืชืžืฉ ื‘ืžื—ืฉื‘ ื”ืจืฉืช ื›ื“ื™ ืœื ืกื•ืช
02:03
tons and tons of different ideas around software.
47

ื”ืžื•ืŸ ื”ืžื•ืŸ ืจืขื™ื•ื ื•ืช ืฉื•ื ื™ื ื‘ืชื•ื›ื ื”.
02:07
Now, after you start getting something like that working,
48
127464
3334
ืขื›ืฉื™ื•, ืื—ืจื™ ืฉืืชื ืžืชื—ื™ืœื™ื ืœื”ืคืขื™ืœ ืžืฉื”ื• ื›ื–ื”,
02:10
you know, a really important problem comes up,
49
130798
2451
ืืชื ื™ื•ื“ืขื™ื, ื‘ืขื™ื” ืžืžืฉ ื—ืฉื•ื‘ื” ืขื•ืœื”,
02:13
like you're wearing this thing on your head,
50
133249
2339
ื›ืžื• ืฉื”ื™ื™ืชื ืจื•ืฆื™ื ืœื—ื‘ื•ืฉ ืืช ื–ื” ืขืœ ื”ืจืืฉ,
02:15
it's like a pair of glasses,
51
135588
1567
ื–ื” ื›ืžื• ื–ื•ื’ ืžืฉืงืคื™ื™ื,
02:17
so you don't have a mouse or a keyboard or a touchscreen,
52
137155
3935
ืื– ืืชื ืœื ืฆืจื™ื›ื™ื ืขื›ื‘ืจ ื•ืžืงืœื“ืช ืื• ืžืกืš ืžื’ืข,
02:21
all the ways you are used to interacting with a machine.
53
141090

ื›ืœ ื”ื“ืจื›ื™ื ืฉืืชื ืจื’ื™ืœื™ื ืืœื™ื”ืŸ ืœื”ืชืžืžืฉืง ืœืžื›ื•ื ื”.
02:25
So, we thought for a second,
54
145223
1837
ืื–, ื—ืฉื‘ื ื• ืœืฉื ื™ื”,
02:27
well, maybe we could do something
55
147060
1179
ื•ื‘ื›ืŸ, ืื•ืœื™ ื ื•ื›ืœ ืœืขืฉื•ืช ืžืฉื”ื•
02:28
like, you know, what was shown in <i>Minority Report</i>.
56
148239
2333
ื›ืžื•, ืืชื ื™ื•ื“ืขื™ื, ืžื” ืฉืจืื• ื‘ืกืจื˜ "ื“ื•ื— ืžื™ื•ื—ื“".
02:30
So, for folks who haven't seen that,
57
150572
1706
ืื–, ืœืื ืฉื™ื ืฉืœื ืจืื• ืืช ื”ืกืจื˜,
02:32
basically Tom Cruise is manipulating software
58
152278
2673
ื‘ืขื™ืงืจื•ืŸ ื˜ื•ื ืงืจื•ื– ืฉื•ืœื˜ ื‘ืชื•ื›ื ื”
02:34

59
154951
1503
ืขื ื™ื“ื™ื• ืžื•ืœ ืคื ื™ื•
02:36
and photos are flying over here
60

ื•ืชืžื•ื ื•ืช ืขืคื•ืช ืคื”
02:38

61
158534
1990
ื•ื”ืื™ืžื™ื™ืœ ืฉืœื• ืฉื
02:40
and so on and so forth.
62
160524
1234
ื•ื›ืš ื”ืœืื”.
02:41
So I'll ask the the same question again,
63
161758
1250
ืื– ืื ื™ ืืฉืืœ ืืช ืื•ืชื” ืฉืืœื” ืฉื•ื‘,
02:43
how long do you think it would take
64
163008
1821
ื›ืžื” ืœื“ืขืชื›ื ื™ืงื—
02:44
to have the real experience of doing something like that?
65
164829
3949
ืœื™ืฆื•ืจ ืืช ื”ื—ื•ื•ื™ื” ื”ืืžื™ืชื™ืช ืฉืœ ืžืฉื”ื• ื›ื–ื”?
02:50
Two years, OK.
66
170518
2766
ืฉื ืชื™ื™ื, ืื•ืงื™ื™.
02:53
Somebody said one day.
67
173284
2475
ืžื™ืฉื”ื• ืืžืจ ื™ื•ื ืื—ื“.
02:55
45 minutes.
68
175759
2414
45 ื“ืงื•ืช.
02:58
So here's how it looks.
69
178173
1414
ืื– ื›ื›ื” ื–ื” ื ืจืื”.
02:59
So you wear the thing that we saw that first time
70
179587
2060
ืื– ืืชื ื—ื•ื‘ืฉื™ื ืืช ื”ื“ื‘ืจ ื”ื–ื” ืฉืจืื™ื ื• ื‘ืคืขื ื”ืจืืฉื•ื ื”
03:01
because you need some way to go project things,
71
181647
2060
ืžืคื ื™ ืฉืืชื ืฆืจื™ื›ื™ื ื“ืจืš ื›ืœืฉื”ื™ ืœื”ืงืจื™ืŸ ื“ื‘ืจื™ื,
03:03
but what happens is we got two hairbands,
72
183707
2446
ืื‘ืœ ืžื” ืฉืงื•ืจื” ื”ื•ื ืฉื™ืฉ ืœื ื• ืฉื ื™ ืกืจื˜ื™ื ืœืฉื™ืขืจ,
03:06
which I think was the hardest part we had to do,
73
186153
1599
ืฉืื ื™ ื—ื•ืฉื‘ ืฉื”ื™ื” ื”ื—ืœืง ื”ื›ื™ ืงืฉื” ืœืขืฉื•ืช,
03:07
ask people for their hairbands.
74
187752
1971
ืชื‘ืงืฉื• ืžืื ืฉื™ื ืืช ื”ืกืจื˜ ืœืฉื™ืขืจ ืฉืœื”ื.
03:09
But you put one hand in each hairband
75
189723
3174
ืื‘ืœ ืืชื ืฉืžื™ื ื›ืœ ื™ื“ ื‘ื›ืœ ืกืจื˜ ืœืฉื™ืขืจ
03:12
and attach that hairband,
76
192897
1737
ื•ืžื—ื‘ืจื™ื ืืช ื”ืกืจื˜ ื”ื–ื”,
03:14
we tied a fishing line.
77
194634
2398
ืงืฉืจื ื• ื—ื•ื˜ ื“ื™ื™ื’.
03:17
And the fishing line goes over the top of a whiteboard
78
197032
2865
ื•ื—ื•ื˜ ื”ื“ื™ื™ื’ ื”ื•ืœืš ืžืขื‘ืจ ืœืœื•ื—
03:19
and then goes down to this little assembly
79
199897
2387
ื•ืื– ื™ื•ืจื“ ืœืชื•ืš ื”ืžื›ืฉื™ืจ ื”ื–ื”
03:22
that's taped to the floor.
80
202284
1550
ืฉืžื—ื•ื‘ืจ ืœืจืฆืคื”.
03:23
And what this means is
81
203834
812
ื•ืžื” ืฉื–ื” ืื•ืžืจ ื–ื”
03:24
every time I move my hand in any direction,
82
204646
2304
ืฉื›ืœ ืคืขื ืฉืื ื™ ืžื–ื™ื– ืืช ื”ื™ื“ ื‘ื›ื™ื•ื•ืŸ ืื—ื“,
03:26
it adds tension to the line
83
206950
1649
ื–ื” ืžื•ืกื™ืฃ ืžืชื— ืœื—ื•ื˜ ื”ื”ื•ื
03:28
and it does the following with the assembly on the floor.
84
208599
3322
ื•ื–ื” ืขื•ืฉื” ืืช ื–ื” ืœืžื›ืฉื™ืจ ืขืœ ื”ืจืฆืคื”.
03:31
So, the other end of the fishing wire is attached to a chopstick
85

ื•ืื– ืœืžืฉื•ืš ืืช ื–ื” ืžืขืœ ืขื˜,

1291
ื•ื‘ืขื™ืงืจื•ืŸ ืžื” ืฉืงื•ืจื” ืื–

1961
ื•ื–ื” ื™ื•ืฆืจ ืžืชื— ืขืœ ื”ื—ื•ื˜,

ืื– ื–ื” ื ื‘ื ื” ื‘ 45 ื“ืงื•ืช

ื•ื–ื” ืืžืจ ืฉืžืขื˜ ืœืื—ืจ ืžื›ืŸ,

ืœืฉืœื•ื˜ ื‘ืชื•ื›ื ื” ื‘ื™ื“ื™ื™ื.

And ultimately, what it taught us is
111
261575

ื•ื‘ืกื•ืคื• ืฉืœ ื“ื‘ืจ, ืžื” ืฉื–ื” ืœืžื“ ืื•ืชื” ื–ื”

We learned a lot of things
113

1045
ืœืžื“ื ื• ื”ืžื•ืŸ
04:26
about the social awkwardness of it

275008
2998
ื•ื—ื•ืง ื”ืื‘ ื˜ื™ืคื•ืก ื”ืฉื ื™,

ื—ื•ืฅ ืื•ืœื™ ืžื”ืงืกื“ื” ืฉื,

ืœืœื‘ื•ืฉ ืžืฉื”ื• ื›ื–ื” ื‘ื ื•ื—ื•ืช?
05:15
The answer is really basic materials:

2939
ื”ืชืฉื•ื‘ื” ื”ื™ื ื—ื•ืžืจื™ื ืžืžืฉ ื‘ืกื™ืกื™ื™ื:

and using something like this
139

971
ื•ืฉื™ืžื•ืฉ ื‘ืžืฉื”ื• ื›ื–ื”
05:21
is able to make something look like a pair of glasses really quickly.

05:29
that we were talking about putting on the device,
143
329253
2457
ืฉื“ื™ื‘ืจื ื• ืขืœ ืœืฉื™ื ื‘ืžื›ืฉื™ืจ,
05:31
wrapped it in paper so you didn't get clay on your face,

05:34
and then taped it to the modeling wire in various places

ื•ืื– ื”ื“ื‘ืงื ื• ืื•ืชื• ืœื—ื•ื˜ ื”ืžื•ื“ืœื™ื ื‘ื›ืœ ืžื™ื ื™ ืžืงื•ืžื•ืช
05:37
to go experiment with how a pair of glasses could fit on you.

05:40
And, we discovered something really important then.
147
340899
2116
ื•ื’ื™ืœื™ื ื• ืžืฉื”ื• ืžืžืฉ ื—ืฉื•ื‘.
05:43
Like, if you look at this drawing on the bottom,
148
343015
2585
ื›ืžื•, ืื ืืชื ืžื‘ื™ื˜ื™ื ื‘ืื™ื•ืจ ื”ื–ื” ืœืžื˜ื”,
05:45
it turns out that the weight of a pair of glasses
149

ืžืกืชื‘ืจ ืฉื”ืžืฉืงืœ ืฉืœ ื–ื•ื’ ืžืฉืงืคื™ื™ื
05:50
is actually mostly perceived
150
350051
1333
ื ืจืื” ืœืžืขืฉื”
05:51
through how much weight is on your nose.
151
351384
2461
ื“ืจืš ื›ืžื” ืžืฉืงืœ ื™ืฉ ืขืœ ืืคื›ื.
05:53
And, it also turns out that your ears can carry
152
353845
2922
ื•ืžืกืชื‘ืจ ื’ื ืฉื”ืื•ื–ื ื™ื™ื ืฉืœื›ื ื™ื›ื•ืœื•ืช ืœืฉืืช
05:56

153
356767
1532
ื”ืจื‘ื” ื™ื•ืชืจ ืžืฉืงืœ ืžื”ืืฃ,
05:58
and that is a totally different experiment,
154
358299
1349
ื•ื–ื” ื ื™ืกื•ื™ ืื—ืจ ืœื’ืžืจื™,
05:59
you can ask me about that.
155
359648
1583
ืืชื ื™ื›ื•ืœื™ื ืœืฉืื•ืœ ืื•ืชื™ ืขืœ ื–ื”.
06:01
But, because of that fact,
156
361970
1812
ืื‘ืœ, ื‘ื’ืœืœ ื”ืขื•ื‘ื“ื” ื”ื–ื•,
06:03
if you put weight behind your ears,
157
363782
2762
ืื ืืชื ืฉืžื™ื ืžืฉืงืœ ืžืื—ื•ืจื™ ื”ืื•ื–ื ื™ื™ื,
06:06
it allows your ear to go act like the fulcrum of a lever
158
366544
3542
ื–ื” ืžืืคืฉืจ ืœื›ื ืœื”ื™ื•ืช ื›ืžื• ื ืงื•ื“ืช ื”ืžืฉืขืŸ ืฉืœ ืžื ื•ืฃ
06:10
and it then takes weight off of your nose on the front.
159
370086
3358
ื•ืื– ื–ื” ืœื•ืงื— ืžืฉืงืœ ืžื”ืืฃ ืžืงื“ื™ืžื”.
06:13
And, actually, you can try this now, anybody with glasses,
160
373444
2108
ื•ืœืžืขืฉื”, ืืชื ื™ื›ื•ืœื™ื ืœื ืกื•ืช ืขื›ืฉื™ื•, ื›ื•ืœื ืขื ืžืฉืงืคื™ื™ื,
06:15
if you push very gently on the back of your glasses,
161
375552
3209
ืื ืชืœื—ืฆื• ื‘ืขื“ื™ื ื•ืช ืขืœ ืื—ื•ืจื™ ืžืฉืงืคื™ื›ื,
06:18
you'll find, actually your glasses feel tremendously lighter.

06:21
Now, this meant that we not only discovered
163
381626
1778
ืขื›ืฉื™ื•, ื–ื” ืื•ืžืจ ืฉืœื ืจืง ื’ื™ืœื™ื ื•
06:23
something interesting about how to go,

ืžืฉื”ื• ืžืขื ื™ื™ืŸ ืขืœ ืื™ืš ืœืขืฉื•ืช ืืช ื–ื”,
06:25
you know, that's useful for developing a device like this,
165
385706

ืืชื ื™ื•ื“ืขื™ื, ื–ื” ื™ืขื™ืœ ืœืคื™ืชื•ื— ืžื›ืฉื™ืจ ื›ืžื• ื–ื”,
06:28
we actually discovered something pretty fundamental
166
388775
1900
ืœืžืขืฉื” ื’ื™ืœื™ื ื• ืžืฉื”ื• ืžืžืฉ ื‘ืกื™ืกื™

ืฉืžืขื•ืœื ืœื ื”ืชื’ืœื” ืขืœ ืžืฉืงืคื™ื™ื, ื ืงื•ื“ื”.
06:33
So, if you have really heavy glasses,
168

1274
ืื–, ืื ื™ืฉ ืœื›ื ืžืฉืงืคื™ื™ื ืžืžืฉ ื›ื‘ื“ื™ื,
06:34
you could do this and you would be more comfortable.
