Saya sangat senang bisa berada di sini hari ini,
00:24
I'm really excited to be here today.

I'll show you some stuff
that's just ready to come out of the lab,
that's just ready to come out of the lab,
1
1898
3102
karena saya akan menunjukkan sesuatu yang baru saja siap untuk keluar dari lab
secara harfiah, dan saya gembira karena Anda semua akan menjadi yang pertama kali
00:29
literally, and I'm really glad
that you guys
that you guys
2
5024
2776
00:31
are going to be among
the first to see it in person,
the first to see it in person,
3
7824
2472
melihat ini secara langsung, karena saya sungguh merasa ini akan mengubah
00:34
because I really think this is going
to really change
to really change
4
10320
2489
-- benar benar mengubah -- cara kita berinteraksi dengan mesin sejak saat ini.
00:36
the way we interact
with machines from this point on.
with machines from this point on.

Nah, ini adalah meja gambar proyeksi-belakang. Besarnya sekitar 36 inchi,
00:39
Now, this is a rear-projected
drafting table.
drafting table.
6
15339
2675
00:42
It's about 36 inches wide
7
18038
1222
dan dilengkapi dengan sensor multi-sentuh. Nah, sensor sentuh normal yang biasa
00:43
and it's equipped
with a multi-touch sensor.
with a multi-touch sensor.
8
19284
2083
00:45
Normal touch sensors that you see,
9
21391
1644
Anda lihat, seperti pada sebuah kios atau papan tulis interaktif
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059
2137
hanya dapat mencatat satu titik sentuh tiap waktu.
00:49
can only register one point
of contact at a time.
of contact at a time.
11
25220
2583
Alat ini memungkinkan Anda untuk mempunyai multi titik bersamaan.
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.
12
28137
3715
Layar ini memanfaatkan kedua tangan, saya bisa bergerak seperti ini,
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876
3314
saya juga bisa lebih dari itu dan menggunakan kesepuluh jari jika mau.
00:59
I can just go right up and use
all 10 fingers if I wanted to.
all 10 fingers if I wanted to.
14
35214
2937
Anda lihat, seperti itu.
01:02
You know, like that.
15
38597
1157
01:03
Now, multi-touch sensing
isn't completely new.
isn't completely new.
16
39778
4543
Penginderaan multi-sentuh bukan hal yang sepenuhnya baru.
Maksud saya, Bill Buxton dan yang lain sudah bermain-main dengan ini sejak 80-an.
01:08
People like Bill Buxton have been
playing around with it in the '80s.
playing around with it in the '80s.
17
44345
3253
Tetapi, alat yang saya gunakan di sini memiliki resolusi tinggi,
01:11
However, the approach I built here
is actually high-resolution,
is actually high-resolution,
18
47622
4028
01:15
low-cost, and probably
most importantly, very scalable.
most importantly, very scalable.
19
51674
2976
rendah biaya, dan mungkin yang paling penting, sangat skalabel
01:19
So, the technology, you know,
20
55000
2337
Jadi, teknologi bukanlah hal yang paling menarik di sini,
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
selain mungkin kemampuan aksesnya yang baru.
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
Yang menarik adalah apa yang bisa dilakukan dengannya,
01:26
What's really interesting here
is what you can do with it
is what you can do with it
23
62173
3525
01:29
and the kind of interfaces
you can build on top of it.
you can build on top of it.
24
65722
2618
dan beragam antarmuka yang bisa Anda buat diatasnya. Jadi mari kita lihat.
01:33
So let's see.
25
69141
1136
Sebagai contoh, kita punya aplikasi lampu lava di sini. Nah, bisa Anda lihat,
01:35
So, for instance, we have
a lava lamp application here.
a lava lamp application here.
26
71111
4313
01:39
Now, you can see,
27
75448
1702
Saya bisa memakai kedua tangan untuk menekan dan membuat gumpalan
01:41
I can use both of my hands to kind
of squeeze and put the blobs together.
of squeeze and put the blobs together.
28
77174
3429
bersamaan. Saya bisa memberikan panas ke sistem ini,
01:44
I can inject heat into the system here,
29
80627
2543
atau saya bisa memisahkannya dengan kedua jari.
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
Sama sekali intuitif; tidak ada petunjuk manual.
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
Program antarmuka nya seakan menghilang.
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
Aplikasi Ini berawal dari semacam screensaver yang dibuat oleh seorang mahasiswa PhD di
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
lab kami, Ilya Rosenberg. Tapi menurut saya seperti inilah karakter aslinya.
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
Nah, yang hebat tentang sensor multi-sentuh adalah, Anda tahu,
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
Saya bisa melakukan ini dengan sebanyak mungkin jari di sini,
02:07
I could be doing this
with as many fingers here,
with as many fingers here,
37
103100
2737
02:09
but of course multi-touch
also inherently means multi-user.
also inherently means multi-user.
38
105861
2978
tetapi tentu saja multi-sentuh juga berarti multi-pemakai.
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
Jadi Chris bisa ada di sini berinteraksi dengan bagian lain lava,
sementara saya bermain di sini. Coba Anda bayangkan peralatan memahat jenis baru,
02:15
while I play around with it here.
40
111386
1634
02:17
You can imagine
a new kind of sculpting tool,
a new kind of sculpting tool,
41
113044
2096
di mana saya bisa memanaskan sesuatu, membuatnya lunak,
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
kemudian membiarkannya mendingin dan mengeras dalam keadaan tertentu.
02:22
and then letting it cool down
and solidifying in a certain state.
and solidifying in a certain state.
43
118167
3258
02:29
Google should have
something like this in their lobby.
something like this in their lobby.
44
125712
2947
Google harusnya punya sesuatu seperti ini di lobi mereka. (Tertawa)
02:32
(Laughter)
45
128683
5293
02:38
I'll show you a little more
of a concrete example here,
of a concrete example here,
46
134000
3272
Saya akan menunjukkan Anda sesuatu -- contoh konkrit lain, setelah alat ini selesai loading.
02:41
as this thing loads.
47
137296
1333
Ini adalah aplikasi light box untuk fotografer.
02:43
This is a photographer's
light-box application.
light-box application.
48
139181
2717
02:45
Again, I can use both of my hands
to interact and move photos around.
to interact and move photos around.
49
141922
3977
Kembali saya gunakan kedua tangan untuk berinteraksi dan memindahkan foto kesana kemari.
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
Tapi yang lebih keren lagi adalah jika saya menggunakan dua jari,
02:53
I can actually grab a photo and then
stretch it out like that really easily.
stretch it out like that really easily.
51
149502
4130
saya bisa meraih sebuah foto dan memperbesarnya dengan sangat mudah.
saya bisa menggeser, memperbesar, lalu memutarnya tanpa kesulitan.
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
saya bisa melakukannya dengan kedua tangan,
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
atau bisa juga hanya dengan dua jari secara bersama-sama.
03:03
or I can do it just with two fingers
on each of my hands together.
on each of my hands together.
54
159501
3204
03:06
If I grab the canvas, I can do
the same thing -- stretch it out.
the same thing -- stretch it out.
55
162729
3027
Jika memegang kanvas, saya bisa melakukan hal yang sama -- merenggangkannya.
Saya bisa melakukannya secara simultan, menahan ini di sini,
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
dan memegang sisi lain, merenggangkannya seperti ini.
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
Lagi lagi, program antarmuka tidak terlihat disini.
03:14
Again, the interface just disappears here.
58
170286
2228
Tanpa manual. Persis seperti apa yang Anda bayangkan,
03:16
There's no manual.
59
172538
1033
03:17
This is exactly what you expect,
60
173595
2302
03:19
especially if you haven't interacted
with a computer before.
with a computer before.
61
175921
3055
bahkan jika Anda tidak pernah berinteraksi dengan komputer sebelumnya.
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
Sekarang, ketika Anda memiliki ide seperti laptop 100 dollar,
03:25
I kind of cringe at the idea
63
181728
1533
Saya bergidik akan ide bahwa kita akan memperkenalkan sebuah generasi baru
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
di mana orang menggunakan komputer dengan mouse-dan-windows seperti ini
03:29
with this standard
mouse-and-windows-pointer interface.
mouse-and-windows-pointer interface.
65
185886
2738
03:32
This is something that I think
is really the way
is really the way
66
188648
3136
Menurut saya seperti inilah seharusnya cara kita berinteraksi dengan mesin
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
sejak sekarang (Tepuk tangan)
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
Nah, tentu saja saya bisa memunculkan keyboard.
03:47
(Laughter)
70
203024
2298
03:52
And I can bring that around,
put that up there.
put that up there.
71
208000
2745
Dan saya bisa menggeser-gesernya lalu menaruhnya di sana.
03:55
Obviously, this is a standard keyboard,
72
211213
1858
Nah, ini adalah sebuah keyboard standar,
tapi tentu saja saya bisa mengubah ukurannya sesuai tangan saya.
03:57
but of course I can rescale it
to make it work well for my hands.
to make it work well for my hands.
73
213095
3082
Dan itu sangatlah penting, karena tidak ada alasan di masa ini
04:00
That's really important, because
there's no reason in this day and age
there's no reason in this day and age
74
216201
3333
kita harus menyesuaikan diri dengan perangkat fisik.
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
Itu bisa berakibat hal-hal yang buruk, seperti RSI.
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
Saat ini kita punya begitu banyak teknologi sehingga
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
antarmukalah yang harus menyesuaikan diri dengan kita.
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
Hanya sebagian kecil yang telah diaplikasikan untuk memperbaiki
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
cara kita berinteraksi dengan antarmuka sejak saat ini.
Keyboard seperti ini pun bisa jadi menuju arah yang salah.
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
Coba Anda bayangkan, di masa depan, sejalan dengan perkembangan teknologi,
04:24
You can imagine, in the future,
as we develop this kind of technology,
as we develop this kind of technology,
82
240366
3302
04:27
a keyboard that kind of automatically
drifts as your hand moves away,
drifts as your hand moves away,
83
243692
3403
sebuah keyboard yang secara otomatis bergerak seiring gerakan tangan Anda,
dan dengan sangat pintar mengantisipasi tombol mana yang ingin Anda tekan.
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
Jadi -- ini hebat kan?
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
Hadirin: Dimana labmu?
04:41
Audience: Where's your lab?
87
257047
1763
04:42
Jeff Han: I'm a research scientist
at NYU in New York.
at NYU in New York.
88
258834
2572
Jeff Han: Saya peneliti riset di NYU, New York
Ini contoh aplikasi lain. Saya bisa membuat bola bola kecil ini.
04:49
Here's an example of another kind of app.
I can make these little fuzz balls.
I can make these little fuzz balls.
89
265341
3635
04:53
It'll remember the strokes I'm making.
90
269000
2334
Dia mengingat bentuk yang saya buat. Saya bisa melakukannya dengan seluruh tangan.
04:55
Of course I can do it with all my hands.
91
271358
1919
Alat ini sensitif terhadap tekanan, bisa Anda lihat.
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
Tetapi yang hebat adalah, sekali lagi, gerakan dua jari yang memungkinkan Anda
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
memperkecil dengan begitu cepat. Karena Anda tidak memerlukan applikasi 'tangan'
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
atau 'kaca pembesar';
05:06
or the magnifying glass tool,
96
282705
1406
Anda bisa terus menerus membuat ini dalam berbagai skala, semua pada saat bersamaan.
05:08
you can just continuously make things
97
284135
2539
05:10
in real multiple scales,
all at the same time.
all at the same time.
98
286698
2354
Saya bisa membuat yang besar di sini, tapi saya bisa dengan cepat kembali
05:13
I can create big things out here,
99
289076
2013
05:15
but I can go back
and really quickly go back
and really quickly go back
100
291113
2098
ke titik mula saya, dan membuat yang lebih kecil di sana.
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
Hal ini menjadi sangat penting ketika kita mengerjakan sesuatu seperti
05:21
This is going to be really important
102
297271
1887
05:23
as we start getting to things
like data visualization.
like data visualization.
103
299182
3033
visualisasi data. Contohnya, saya rasa kita semua menikmati ceramah Hans Rosling,
05:26
For instance, I think
we all enjoyed Hans Rosling's talk,
we all enjoyed Hans Rosling's talk,
104
302239
2667
05:28
and he really emphasized the fact
I've been thinking about for a long time:
I've been thinking about for a long time:
105
304930
3526
dan beliau sangat menekankan fakta yang juga telah saya pikirkan sejak lama:
kita punya berbagai data, tetapi karena sejumlah alasan, data itu hanya tersimpan disana.
05:32
We have all this great data,
106
308480
1351
05:33
but for some reason,
it's just sitting there.
it's just sitting there.
107
309855
2097
Kita tidak benar-benar mengaksesnya. Salah satu alasannya menurut saya, adalah karena
05:35
We're not accessing it.
108
311976
1119
05:37
And one of the reasons why I think that is
109
313119
3523
05:40
will be helped by things like graphics
and visualization and inference tools,
and visualization and inference tools,
110
316666
4716
-- kita akan sangat tertolong oleh hal-hal seperti peralatan grafik, visualisasi dan fasilitas antarmuka.
Tapi saya pikir kita juga perlu untuk mulai memiliki fasilitas antarmuka yang lebih baik,
05:45
but I also think a big part of it
111
321406
1861
05:47
is going to be having better interfaces,
112
323291
2056
untuk mampu menggali ke dalam data-data tersebut, sambil tetap mempertimbangkan gambaran besarnya.
05:49
to be able to drill down
into this kind of data,
into this kind of data,
113
325371
2240
05:51
while still thinking
about the big picture here.
about the big picture here.
114
327635
2338
05:54
Let me show you another app here.
This is called WorldWind.
This is called WorldWind.
115
330460
2979
Ijinkan saya menunjukkan aplikasi lain. Kami menyebut ini WorldWind.
Ini dibuat oleh NASA. Sejenis Google Earth yang sering kita lihat;
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
ini versi open-source. Terdapat plug-in yang bisa
06:01
this is an open-source version of that.
118
337480
1958
06:03
There are plug-ins to be able
to load in different data sets
to load in different data sets
119
339462
3524
menampilkan berbagai set data yang dikumpulkan NASA selama bertahun-tahun.
06:07
that NASA's collected over the years.
120
343010
1799
06:08
As you can see, I can use
the same two-fingered gestures
the same two-fingered gestures
121
344833
2620
Tapi seperti yang Anda lihat, saya bisa memakai gerakan dua-jari yang sama
untuk turun dan mendekat tanpa hambatan. Sekali lagi tanpa antarmuka.
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
Ini memungkinkan siapapun untuk mendekat-- ini lah yang Anda harapkan,
06:15
It really allows anybody
to kind of go in --
to kind of go in --
124
351387
3271
06:18
and it just does
what you'd expect, you know?
what you'd expect, you know?
125
354682
2963
betul kan? Sekali lagi, tidak ada antarmuka di sini. Menghilang begitu saja.
06:21
Again, there's just no interface here.
The interface just disappears.
The interface just disappears.
126
357669
3272
06:27
I can switch to different data views.
127
363000
1876
Saya bisa beralih ke tampilan data lain. Itu lah kehebatan applikasi ini.
06:28
That's what's neat about this app here.
128
364900
2194
Itu dia. NASA begitu keren. Mereka punya gambar-gambar hiper-spektral ini
06:31
NASA's really cool.
129
367118
1157
06:32
These hyper-spectral images
are false-colored so you can --
are false-colored so you can --
130
368299
2762
dengan warna--sangat bagus untuk penentuan pemanfaatan vegetasi. OK, kembali ke sini.
06:35
it's really good for determining
vegetative use.
vegetative use.
131
371085
3943
06:39
Well, let's go back to this.
132
375887
1586
Nah, yang hebat soal aplikasi pemetaan --
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
dia bukan 2D, tapi 3D. Jadi, dengan sebuah antarmuka multi-titik,
06:46
it's not really 2D, it's 3D.
134
382510
1490
06:48
So, again, with a multi-point interface,
you can do a gesture like this --
you can do a gesture like this --
135
384024
3492
Anda dapat melakukan gerakan ini -- dan Anda bisa memiringkannya seperti itu,
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
Ini tidak bisa disamakan begitu saja dengan pergeseran dan gerakan 2D
06:55
(Surprised laughter)
137
391001
1874
06:56
It's not just simply relegated
to a kind of 2D panning and motion.
to a kind of 2D panning and motion.
138
392899
3182
Nah, gerakan yang kami kembangkan, hanya dengan menaruh dua buah jari,
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
sumbu kemiringan ditentukan, dan saya bisa memiringkannya ke atas dan ke bawah.
07:02
it's defining an axis of tilt --
and I can tilt up and down that way.
and I can tilt up and down that way.
140
398764
3653
Ide seperti ini muncul begitu saja.
07:06
We just came up with that on the spot,
141
402441
2078
Bisa jadi ini bukanlah hal yang benar untuk dilakukan,
07:08
it's probably not the right thing to do,
142
404543
1937
tapi terdapat hal-hal menarik yang bisa Anda lakukan dengan antarmuka itu.
07:10
but there's such interesting things
you can do with this interface.
you can do with this interface.
143
406504
3229
07:15
It's just so much fun
playing around with it, too.
playing around with it, too.
144
411000
2934
Begitu menyenangkan untuk bermain-main. (Tertawa)
07:17
(Laughter)
145
413958
1353
Jadi hal terakhir yang ingin saya tunjukkan--
07:19
And so the last thing
I want to show you is --
I want to show you is --
146
415335
2641
07:22
I'm sure we can all think
of a lot of entertainment apps
of a lot of entertainment apps
147
418000
2677
saya yakin kita bisa memikirkan begitu banyak aplikasi hiburan
yang bisa dilakukan dengan ini.
07:24
that you can do with this thing.
148
420701
1524
Saya agak tertarik dengan aplikasi kreatif yang bisa dilakukan dengan ini.
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
Ini adalah sebuah aplikasi sederhana --saya menggambar sebuah kurva
07:30
Now, here's a simple application here --
I can draw out a curve.
I can draw out a curve.
150
426323
3237
Ketika ditutup, kurva itu menjadi sebuah karakter.
07:35
And when I close it,
it becomes a character.
it becomes a character.
151
431201
3266
07:38
But the neat thing about it
is I can add control points.
is I can add control points.
152
434785
2977
Hebatnya, saya bisa menambahkan titik-titik kontrol.
07:41
And then what I can do is manipulate them
with both of my fingers at the same time.
with both of my fingers at the same time.
153
437786
3977
Dan saya bisa memanipulasinya dengan dua jari pada saat yang sama.
07:45
And you notice what it does.
154
441787
1903
Dan lihat apa yang terjadi.
07:48
It's kind of a puppeteering thing,
155
444253
2555
Seperti bermain wayang, saya bisa menggunakan
07:50
where I can use as many fingers
as I have to draw and make --
as I have to draw and make --
156
446832
5218
sebanyak mungkin jari untuk menggambar dan membuat --
Terdapat begitu banyak perhitungan matematis di sini
08:02
Now, there's a lot of actual math
going on under here
going on under here
157
458274
2702
08:05
for this to control this mesh
and do the right thing.
and do the right thing.
158
461000
4442
untuk mengatur bidang ini dan melakukan hal yang benar.
Maksud saya, teknik yang mampu memanipulasi bidang ini,
08:10
This technique of being able to manipulate
a mesh here, with multiple control points,
a mesh here, with multiple control points,
159
466183
5692
dengan titik kontrol lebih dari satu, merupakan teknologi termutakhir.
08:15
is actually state of the art.
160
471899
1476
Ini baru dirilis di Siggraph tahun lalu,
08:17
It was released at SIGGRAPH last year.
161
473399
1824
tapi seperti itulah tipe riset yang benar-benar saya sukai.
08:19
It's a great example
of the kind of research I really love:
of the kind of research I really love:
162
475247
2770
Memanfaatkan komputasi untuk membuat berbagai hal melakukan hal yang benar.
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
hal-hal yang intuituf. Untuk melakukan sesuatu sesuai harapan.
08:24
intuitive things,
to do exactly what you expect.
to do exactly what you expect.
164
480864
2721
08:31
So, multi-touch interaction research
is a very active field right now in HCI.
is a very active field right now in HCI.
165
487000
4658
Jadi, riset interaksi multi-sentuh adalah bidang yang saat ini sangat aktif di HCI.
08:36
I'm not the only one doing it,
a lot of other people are getting into it.
a lot of other people are getting into it.
166
492000
3476
Saya bukan satu-satunya, ada banyak orang lain yang bekerja di bidang ini.
Teknologi ini akan menarik semakin banyak orang untuk bergabung,
08:39
This kind of technology is going to let
even more people get into it,
even more people get into it,
167
495500
3245
dan saya menantikan saat berinteraksi dengan Anda semua
08:42
I'm looking forward to interacting
with all of you over the next few days
with all of you over the next few days
168
498769
3492
beberapa hari ke depan dan melihat kemungkinan aplikasi sesuai bidang Anda masing-masing.
08:46
and seeing how it can apply
to your respective fields.
to your respective fields.
169

ABOUT THE SPEAKER
Jeff Han - Human-computer interface designerAfter years of research on touch-driven computer displays, Jeff Han has created a simple, multi-touch, multi-user screen interface that just might herald the end of the point-and-click era.
Why you should listen
Jeff Han's intuitive "interface-free" computer displays -- controlled by the touch of fingertips -- will change forever the way you think about computers. At TED 2006, the audience whistled, clapped and gasped audibly as Han demoed (for the first time publicly) his prototype drafting table-cum-touch display, developed at NYU's Courant Institute of Mathematical Sciences. The demo included a virtual lightbox, where he moved photos by fingertip -- as if they were paper on a desk -- flicking them across the screen and zooming in and out by pinching two fingers together, as well as a Google Earth-like map that he tilted and flew over with simple moves.
When the demo hit the web, bloggers and YouTubers made him a bit of a megastar. (His video has been watched more than 600,000 times on YouTube alone; "Amazing," "Incredible" and "Freaking awesome" are the typical responses there. Also: "When can I buy one?") After this legendary demo, Han launched a startup called Perceptive Pixel -- and when he came back to TED2007, he and his team brought an entire interactive wall, where TEDsters lined up to play virtual guitars. His talent and reputation earned him a place on Time Magazine's 2008 list of the world's 100 Most Influential People.
