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,

jer ću vam pokazati neke od stvari koje su spremne izaći iz laboratorija,
doslovno, i jako mi je drago da ćete vi biti prvi koji ćete moći
00:29
literally, and I'm really glad
that you guys
that you guys
2

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
to vidjeti uživo, jer ja zapravo, stvarno mislim da će to promijeniti
00:34
because I really think this is going
to really change
to really change
4
10320
2489
-- zaista promijeniti -- način na koji smo u interakciji sa strojevima od sad pa nadalje.
00:36
the way we interact
with machines from this point on.

Ovo je pozadinski projiciran stol za skiciranje. Širok je oko 36 inča
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
i opremljen je senzorom za višestruki dodir. Normalni senzori na dodir koje
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
vidite, na kiosku ili interaktivnim pločama,
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059
2137
mogu registrirati samo jednu točku dodira.
00:49
can only register one point
of contact at a time.
of contact at a time.
11
25220
2583
Ova stvar vam dozvoljava da imate više dodirnih točaka u isto vrijeme.
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.
12
28137

Mogu koristiti obje ruke, mogu koristiti vezujuće akcije,
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876
3314
i mogu koristiti svih 10 prstiju ukoliko to želim.
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
Znate, ovako.
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
Podrška za višestruke dodire nije potpuno nova.
Mislim, ljudi kao što je Bill Buxton igraju se s tim od osamdesetih godina.
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
No unatoč tome, pristup koji sam ja ovdje izgradio je visoka rezolucija,
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
nizak trošak, i vjerojatno najvažnije, vrlo proizvodno.
01:19
So, the technology, you know,
20
55000
2337
Dakle, tehnologija ovdje nije najuzbudljivija stvar trenutno,
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
već samo novopronađena pristupačnost.
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
Ono što je ovdje zaista zanimljivo je to što možete činiti s tim,
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
i kakva sučelja se mogu graditi na osnovu toga. Pa pogledajmo.
01:33
So let's see.
25
69141
1136
Dakle, za primjer, imamo aplikaciju lava lampe ovdje. Sada možete vidjeti,
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
mogu koristiti obje svoje ruke tako da stisnem mrlje i
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
spojim ih. Mogu dodati toplinu u sustav ovdje,
01:44
I can inject heat into the system here,
29
80627
2543
ili ga mogu razdvojiti sa moja dva prsta.
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
Potpuno je intiutivna, nema priručnika s uputama.
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
Sučelje jednostavno nestaje.
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
Ovo je počelo kao aplikacija čuvara zaslona koju je jedan od studenata na doktoratu
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
u našem laboratoriju, Ilya Rosenberg, napravio. Ali mislim da se njegov pravi identitet pokazuje ovdje.
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
Ono što je odlično kod senzora za više dodira,
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
je to da bi ovo mogao raditi s jednako toliko prstiju ovdje,
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
ali naravno višestruki dodir automatski znači više korisnika.
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
Tako da bi Chris mogao biti ovdje u interakciji s drugim dijelom Lave,
dok se ja igram s tim ovdje. Možete zamisliti novu vrstu alata za oblikovanje,
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
gdje ja zagrijavam nešto, činim ga podatnijim,
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
i onda puštam da se ohladi i učvrsti u određeno stanje.
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 bi trebao imati ovako nešto u svom predvorju. (Smijeh)
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
Pokazat ću vam nešto -- jedan malo konkretniji primjer ovdje, dok se ova stvar učitava.
02:41
as this thing loads.
47
137296
1333
Ovo je aplikacija light box za fotografe.
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
Opet, mogu koristiti obje svoje ruke i pomicati slike uokolo.
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
Ali ono što je bolje je ako imam dva prsta,
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
mogu zaista zgrabiti fotografiju i rastegnuti je ovako zaista lako.
Mogu pregledavati, zumirati i rotirati ih bez problema.
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
To mogu ugrubo raditi s obje svoje ruke,
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
ili samo s dva prsta na svakoj ruci zajedno.
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
Ako zgrabim platno, mogu napraviti istu stvar -- rastegnuti ga.
Mogu to raditi istovremeno, dok ovo držim,
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
i hvatam drugo, rastežem ga ovako.
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
Ponovno, sučelje samo nestaje ovdje.
03:14
Again, the interface just disappears here.
58
170286
2228
Nema priručnika. Ovo je točno ono što očekujete,
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
posebno zato što niste bili u interakciji s računalom prije.
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
Sad, kad imate inicijative kao što je laptop od 100 dolara,
03:25
I kind of cringe at the idea
63
181728
1533
ja se hvatam ideje da ćemo uvesti potpuno novu generaciju ljudi
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
koja će se koristiti ovim sučeljem za miš i prozore.
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
Ovo je nešto za što smatram da je način na koji bi korisnik trebao surađivati sa strojevima
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
od sad pa nadalje. (Pljesak)
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
Naravno, mogu pozvati tipkovnicu.
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
I mogu to pomicati, staviti gore.
03:55
Obviously, this is a standard keyboard,
72
211213
1858
Naravno, ovo je standardna tipkovnica,
ali mogu je povećati kako bi dobro radila s mojim rukama.
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
I to je zaista važno, jer nema razloga da u ovom dobu
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
se moramo ograničavati na fizičke uređaje.
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
To vodi do loših stvari, kao što je ozljeda ponavljajućeg napora.
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
Imamo tako puno tehnologije danas da bi se ova
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
sučelja morala početi prilagođavati nama.
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
Tako malo se koristi trenutno za poboljšanje
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
načina na koji smo u interakciji sa sučeljima od sad pa nadalje.
Ova tipkovnica je zapravo krivi smjer u kojem idemo.
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
Možete zamisliti, u budućnosti, dok razvijamo ovu tehnologiju,
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
tipkovnicu koja se automatski kreće kako vam se miče ruka,
i zaista inteligentno predviđa koju tipku pokušavate pritisnuti rukom.
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
Dakle -- ponovno, zar ovo nije odlično?
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
Publika: Gdje vam je laboratorij?
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: Ja sam znanstvenik istraživač na sveučilištu u New Yorku.
Ovdje je primjer druge vrste aplikacije. Mogu napraviti ove male loptice.
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
Zapamtiti će pokrete koje radim. Naravno sve to mogu napraviti rukama.
04:55
Of course I can do it with all my hands.
91
271358
1919
Osjetljivo je na dodir, možete primjetiti.
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
Ali ono što je zgodno, ponovno, pokazao sam vam tu gestu s dva prsta koja vam dozvoljava
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
da zumirate vrlo brzo. Jer niste se morali prebaciti na ručni alat
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
ili povećalo;
05:06
or the magnifying glass tool,
96
282705
1406
možete kontinuirano praviti stvari u različitim veličinama, sve u isto vrijeme.
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
Mogu stvoriti velike stvari ovdje, ali mogu se i vratiti i vrlo brzo se vratiti
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
na početak, i raditi još manje stvari ondje.
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
Sada će ovo biti vrlo važno kada se počnemo baviti stvarima kao što je
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
vizualizacija podataka. Na primjer, mislim da smo svi uživali u govoru Hansa Roslinga,
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
i on je zaista naglasio činjenicu o kojoj sam i ja razmišljao jako dugo:
imamo sve ove odlične podatke, ali iz nekog razloga, oni samo stoje.
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
Ne pristupamo im. I jedan od razloga zašto je to tako, je zbog
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
-- pomagat će nam stvari kao grafički i vizualizacijski alati.
Ali mislim da će i velik dio toga biti početak razvoja mogućnosti sučelja,
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
da možemo uroniti u ovakve podatke, dok još uvijek mislimo na veliku sliku.
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
Dopustite da vam pokažem još jednu aplikaciju ovdje. Ovo se zove WorldWind.
NASA izrađuje taj program. To je nešto kao -- pa, svi smo vidjeli Google Earth;
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
ovo je verzija otvorenog koda toga. Postoje priključci koji omogućuju
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
učitavanje različitih setova podataka koje je NASA skupila kroz godine.
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
Ali kao što možete vidjeti, mogu se služiti istom gestom s dva prsta
da siđemo dolje i uđemo gotovo neprimjetno. Ponovno nema sučelja.
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
Dozvoljava svakome da uđe -- i, radi točno ono što očekujete,
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
znate? Ponovno, ovdje nema sučelja. Sučelje nestaje.
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
Mogu se prebacivati na pregled drugačijih podataka. To je ono što je zgodno kod ove aplikacije.
06:28
That's what's neat about this app here.
128
364900
2194
Eto ga. NASA je zaista kul. Imaju ove hiper-spektralne slike
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
koje su lažno bojane kako biste -- stvarno su dobre za određivanje rasprostranjenosti vegetacije. Pa, vratimo se ovome.
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
Super stvar kod aplikacija s kartama --
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
nisu zaista 2D, to je na neki način 3D. Dakle, ponovno sučelje s više točaka,
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
možete napraviti ovakvu gestu -- tako da ih možete naginjati ovako,
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
znate. Nije ograničeno na 2D pokrete i pregled.
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
Ova gesta koju smo razvili, ponovno, je samo stavljanje dva prsta dolje,
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
definira os naginjanja, i možete naginjati gore ili dolje na taj način.
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
To je nešto što smo smislili na licu mjesta,
07:06
We just came up with that on the spot,
141
402441
2078
znate, to vjerojatno nije dobra stvar za učiniti,
07:08
it's probably not the right thing to do,
142
404543
1937
ali postoji toliko zanimljivih stvari koje možete činiti s ovakvim sučeljem.
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
Jednako je zabavno samo se igrati s tim. (Smijeh)
07:17
(Laughter)
145
413958
1353
Zadnja stvar koju vam želim pokazati je --
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
znate, siguran sam da možemo osmisliti puno zabavnih aplikacija
koje možemo ostvariti s ovom stvari.
07:24
that you can do with this thing.
148
420701
1524
Ja sam malo više zainteresiran za kreativne aplikacije koje možemo napraviti s ovim.
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
Ovdje je jedna jednostavna aplikacija -- mogu nacrtati krivulju.
07:30
Now, here's a simple application here --
I can draw out a curve.
I can draw out a curve.
150
426323
3237
I kada je zatvorim, postaje znak.
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
Ali odlična stvar kod ovoga je, da mogu dodati kontrolne točke.
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
I ono što mogu činiti tada je kontrolirati ih s oba prsta u isto vrijeme.
07:45
And you notice what it does.
154
441787
1903
I primjećujete što čini.
07:48
It's kind of a puppeteering thing,
155
444253
2555
To je kao stvar kod lutkarstva, gdje mogu koristiti
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
koliko god prstiju želim za crtanje i pravljenje --
Ispod površine događa se puno prave matematike
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
kako bi se sve kontroliralo i napravila se prava stvar.
Mislim, tehnika kojom kontroliramo mrežu ovdje,
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
s više kontrolnih točaka, je zapravo nešto što je potpuno novo.
08:15
is actually state of the art.
160
471899
1476
Tek je pušteno u javnost na Siggraphu prošle godine,
08:17
It was released at SIGGRAPH last year.
161
473399
1824
ali je odličan primjer istraživanja kakvo ja zaista volim.
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
Sva ova snaga računanja kako bi ove stvari radile ono što želimo.
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
Intiutivne stvar. Da radi točno ono što očekujete.
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
Interakcija s više dodira je sada vrlo aktivno područje trenutno u interakciji ljudi i računala.
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
Nisam jedini koji se time bavi, postoji mnoštvo ljudi koji se uključuju u to.
Ova vrsta tehnologije dopustit će sve više ljudi da se uključi,
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
i zaista se veselim interakciji sa svima vama
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
kroz sljedećih nekoliko dana, kako bismo vidjeli kako se ovo može primjeniti na vašim područjima rada.
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.
