Sunt foarte încântat să fiu astăzi aici,
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
pentru că sunt pe cale să vă arăt ceva care e gata să iasă din laborator,
literalmente, şi sunt foarte bucuros că veți fi printre primii care
00:29
literally, and I'm really glad
that you guys
that you guys

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
o să-l vedeți cu ochii voștri pentru că într-adevăr cred că asta va schimba
00:34
because I really think this is going
to really change
to really change
4
10320
2489
cu adevărat modul în care interacţionăm cu computerele de acum încolo.
00:36
the way we interact
with machines from this point on.
with machines from this point on.
5
12833
2482
E o interfață de interacțiune cu proiectare din spate, lat de aprox. 1m,
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
și e echipat cu un senzor multi-touch. Senzorii de atingere normali
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
pe care-i vedeți, de exemplu la un chioşc sau un whiteboard (tablă interactivă),
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059
2137
pot înregistra doar un singur punct de contact deodată.
00:49
can only register one point
of contact at a time.
of contact at a time.
11
25220
2583
Acesta însă permite să aveţi mai multe puncte în acelaşi timp.
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.
12

Pot folosi ambele mâini, pot folosi acţiunile chording,
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876
3314
şi pot chiar folosi toate10 degetele,
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
Uite așa.
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
Dar senzorii multi-touch nu sunt complet noi.
Adică, oameni ca Bill Buxton s-au jucat cu ideea în anii 80.
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
Dar abordarea pe care am construit-o eu aici e de înaltă rezoluţie,
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
ieftină şi poate cel mai important, foarte scalabilă.
01:19
So, the technology, you know,
20
55000
2337
Acum, tehnologia nu e lucrul cel mai interesant aici,
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
în afară doar, probabil, de accesibilitatea dobândită.
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
Ce e cu adevarat interesant e ceea ce poți face cu ea,
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
şi genul de interfeţe ce se pot construi cu ea. Deci, să vedem.
01:33
So let's see.
25
69141
1136
De exemplu, avem aici o aplicație: lampă de lavă.
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
Vedeți, pot folosi ambele mâini să strâng şi să adun lava.
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
Pot injecta căldură în sistem
01:44
I can inject heat into the system here,
29
80627
2543
sau pot să-l despic cu două degete.
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
E complet intuitiv, nu există manual de instrucţiuni.
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
Interfaţa într-un fel dispare.
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
A început ca o applicație de screensaver pe care l-a făcut
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
un student doctorand din laboratorul nostru, Ilya Rosenberg. Dar cred ca identitatea sa reala iese la iveala aici.
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
Ceea ce-i grozav la un senzor de multi-touch este că,
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
aș putea face asta cu oricâte degete,
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
dar, desigur, multi-touch înseamnă implicit multi-user.
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
Deci, Chris ar putea interacționa acolo cu o altă parte de Lavă,
în timp ce eu mă joc aici. Vă puteţi imagina un nou tip de instrument de sculptură,
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
unde eu într-un fel încălzesc, ceea ce-l face maleabil,
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
şi apoi lasându-l sa se răcească și să se solidifice într-o anumită stare.
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 ar trebui să aibă ceva de genul ăsta la intrare în foyer. (Râsete)
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
Vă voi arata ceva-- un exemplu mai concret când asta se încarcă.
02:41
as this thing loads.
47
137296
1333
Aceasta e o aplicație: cutia de lumină a fotografului.
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
Din nou, pot folosi ambele mâini pentru a interacţiona şi muta fotografiile.
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
Dar ceea ce-i chiar mai grozav e că, dacă folosesc două degete,
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
pot apuca o fotografie şi apoi o pot mări foarte ușor.
O pot muta, focaliza, sau roti fără efort.
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
Pot face asta grosolan cu ambele mâini,
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
sau o pot face doar cu două degete de la o mână.
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
Dacă apuc pânza, pot face acelaşi lucru , s-o măresc.
Pot s-o fac simultan în timp ce țin asta jos
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
și să apuc alta, mărind-o așa.
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
Din nou, interfața pur si simplu dispare aici.
03:14
Again, the interface just disappears here.
58
170286
2228
Nu e nici un manual. Asta-i exact ceea ce te astepți,
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
mai ales dacă nu aţi interacţionat cu un computer înainte.
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
Acum, când aveți iniţiative cum e laptopul de 100 dolari,
03:25
I kind of cringe at the idea
63
181728
1533
oarecum mă gândesc cu regret că vom introduce unei întregi generații
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
computere cu această interfață standard: mouse și windows.
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
Cred că acesta este modul în care ar trebui să interacționăm
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
din acest moment. (Aplauze)
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
Acum, desigur, pot face să apară o tastatură.
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
Și o pot muta și pune aici.
03:55
Obviously, this is a standard keyboard,
72
211213
1858
Evident, asta e o tastatură standard,
dar, desigur, o pot re-dimensiona ca să se potrivească bine pentru mâinile mele.
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
Şi asta e foarte important deoarece nu există nici un motiv în această eră
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
să trebuiască să ne conformăm unui dispozitiv fizic.
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
Asta duce la probleme medicale rele, cum e RSI (Repetitive Strain Injury)
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
Avem atâta tehnologie în ziua de azi că
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
aceste interfețe ar trebui să înceapă să ni se conformeze nouă.
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
E prea puțin aplicat pentru a îmbunătăți felul în care
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
interacționăm cu interfețele de acum înainte.
Această tastatură e poate direcţia greşită.
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
Vă imaginați în viitor vom dezvolta acest tip de tehnologie,
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
o tastatură care derivă când mâna se îndepărtează
şi foarte inteligent anticipează ce cheie încercați să tastați.
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
Ce credeți, nu-i grozav?
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
Audienţa: Unde e laboratorul dumneavoastră?
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: Lucrez în cercetare la Universitatea New York, NY.
Iată un alt exemplu de aplicație. Pot face aceste mici baloane de puf.
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
Va memora mișcările pe care le fac. Pot acționa cu ambele mâini.
04:55
Of course I can do it with all my hands.
91
271358
1919
E sensibil la presiune, după cum vedeți.
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
Un parametru remarcabil, v-am arătat că puteți focaliza rapid cu două degete.
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
Pentru ca nu trebuie să recurgeți la un instrument de mână
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
sau instrumentul lupă,
05:06
or the magnifying glass tool,
96
282705
1406
puteţi acționa simultan în scale multiple, totul în același timp.
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
Pot magnifica obiecte dar pot merge înapoi foarte repede
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
de unde am pornit, și să micșorez obiectele.
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
Va fi important când ajungem la aspecte ca vizualizarea de date.
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
De exemplu, cred că tuturor ne-a plăcut prezentarea lui 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
și el a accentuat aspectul la care m-am tot gândit de-o vreme încoace:
avem multe date, dar nu se știe de ce stau nefolosite.
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
Nu le accesăm. Și unul din motive e că
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
vom fi ajutați de grafice, vizualizare, unelte de deducție.
Dar cred ca o mare parte e că așteptăm și să apară interfețe mai bune,
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
să putem fora în aceste date în timp ce păstrăm privirea de ansamblu aici.
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
Să vă arăt încă o aplicație. Se numește WorldWind.
E făcută de NASA. E un fel de --- toți am văzut Google Earth;
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
asta e o versiune open-sorce. Există plug-ins pentru a putea să
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
încarce diverse date colectate de NASA de-a lungul anilor.
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
Dar după cum vedeți, pot folosi două degete
să cobor și să intru foarte lejer. Nu există nici o interfață.
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
Permite oricui să se alăture -- și face intuitiv exact ce te aștepți
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
Din nou, nu există interfață. Interfața dispare.
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
Pot schimba la vizualizări de date diferite. Asta-i grozav la această aplicație.
06:28
That's what's neat about this app here.
128
364900

Iată. NASA e într-adevăr grozavă. Au aceste imagini hyper-spectrale
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
care sunt codificate în culori false -- bune pentru uzanță vegetativă. Ei bine sa ne intoarcem.
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
Ce-i grozav la aplicațiile de cartografiere
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
nu sunt 2D, ci un fel de 3D. Deci, cu o interfață multi-point
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
poți face un gest ca acesta -- ca să-l răstorni așa,
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
Nu este restricționat doar la mutare și mișcare 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
Acest gest pe care l-am programat constă în a pune 2 degete jos
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
delimitând o axă de înclinare și-l pot apleca în sus și jos.
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
Asta am adăugat pur și simplu pe loc
07:06
We just came up with that on the spot,
141
402441
2078
poate nu-i cel mai bun lucru pe care puteam să-l facem
07:08
it's probably not the right thing to do,
142
404543
1937
dar poți face lucruri atat de interesante cu o astfel de interfață.
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
E și atât de distractiv să te joci cu ea.(Râsete)
07:17
(Laughter)
145
413958
1353
Ultimul lucru pe care vreau să vi-l arăt este --
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
sunt sigur că ne putem gândi la o mulţime de aplicaţii de divertisment
pe care le puteţi face cu acest lucru.
07:24
that you can do with this thing.
148
420701
1524
Sunt mai interesat în aplicaţiile creative pe care le putem face.
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
Aici e o aplicație simplă -- pot desena o curbă.
07:30
Now, here's a simple application here --
I can draw out a curve.
I can draw out a curve.
150
426323
3237
Și când o închid devine o figură animată.
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
Dar grozav e că pot adăuga puncte de control.
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
Și atunci pot să le manipulez cu ambele degete în acelaşi timp.
07:45
And you notice what it does.
154
441787
1903
Şi observaţi ce face.
07:48
It's kind of a puppeteering thing,
155
444253
2555
Este un fel de lucru păpușar la care pot folosi
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
oricâte degete ca să desenez şi să modelez --
Există multă matematică ce are loc aici
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
pentru a controla această angrenare şi a face ceea ce trebuie.
Această tehnică de a fi capabil să manipulezi un sistem-plasă
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
cu mai multe puncte de control, e de fapt de ultimă oră în tehnologie.
08:15
is actually state of the art.
160
471899
1476
Asta tocmai a fost lansată la Siggraph anul trecut,
08:17
It was released at SIGGRAPH last year.
161
473399
1824
dar e un exemplu bun de cercetare care îmi place.
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
O mare putere de calcul e aplicată pentru a opera corect și intuitiv.
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
Pentru a face exact ceea ce vă aşteptaţi.
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
Cercetarea în interacţiunea multi-touch este un domeniu foarte activ în acest moment la 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
Eu nu sunt singurul, sunt multe alte persoane care sunt implicate.
Această tehnologie va atrage tot mai mulți oameni
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
și aștept cu nerăbdare să interacționez cu voi
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
în următoarele câteva zile şi să vedem cum se poate aplica în domeniile voastre.
08:46
and seeing how it can apply
to your respective fields.
to your respective fields.

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.
