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,

porque les mostrare algo que está, literalmente, listo para salir del
laboratorio, y estoy realmente contento que ustedes estén entre los primeros en
00:29
literally, and I'm really glad
that you guys
that you guys

00:31
are going to be among
the first to see it in person,
the first to see it in person,

7824
2472
verlo en persona, porque honestamente creo que esto cambiará
00:34
because I really think this is going
to really change
to really change

10320
2489
-- realmente cambiará -- la manera en la que interactuamos con las máquinas de ahora en adelante.
00:36
the way we interact
with machines from this point on.

Ahora, éste es una mesa de dibujo de proyección trasera. Mide aproximadamente 36 pulgadas de ancho,
00:39
Now, this is a rear-projected
drafting table.

6
15339
2675
00:42
It's about 36 inches wide

y está equipada con un sensor multi-táctil. Los sensores táctiles normales que
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
pueden ver, en un kiosco o en pizarras interactivas,
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059

sólo pueden registrar un punto de contacto a la vez.
00:49
can only register one point
of contact at a time.

Esta mesa les permite tener múltiples puntos al mismo tiempo.
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.

Puede usar mis dos manos, puedo ejecutar acciones coordinadas,
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876

y puedo seguir aumentando y usar los 10 dedos si quisiera.
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
Así, de este modo.
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
Ahora, la sensibilidad multi-táctil no es completamente nueva.
Personas como Bill Buxton han estado jugando con esto desde los 80's.
01:08
People like Bill Buxton have been
playing around with it in the '80s.
playing around with it in the '80s.
17
44345

Sin embargo, el enfoque que he construido es de alta resolución,
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
bajo costo, y probablemente lo más importante, muy escalable.
01:19
So, the technology, you know,
20
55000
2337
Entonces, la tecnología, sabrán, no es lo más emocionante de esto,
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
exceptuando probablemente su renovada accesibilidad.
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
Lo que es realmente interesante es lo que pueden hacer con esto,
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
y los tipos de interfaces que se pueden construir sobre ella. Entonces, veamos.
01:33
So let's see.
25
69141
1136
Por ejemplo, tenemos una aplicación de lámpara de lava. Ahora, como pueden ver,
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
puedo usar ambas manos para apretar y juntar
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
las manchas. Puedo inyectar calor al sistema,
01:44
I can inject heat into the system here,
29
80627
2543
o separarlo con dos de mis dedos.
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
Es completamente intuitivo; no hay manual de instrucciones.
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
La interfaz prácticamente desaparece.
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
Esto empezó como salvapantallas que uno de los estudiantes del Ph. D.
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
en nuestro laboratorio, Ilya Rosenberg, construyó. Pero creo que su verdadera identidad aparece acá.
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
Ahora, lo que es genial respecto al sensor multi-táctil es que
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
podría estar haciendo esto con todos los dedos,
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
pero, por supuesto, multi-táctil también significa, inherentemente, multi-usuario.
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
Entonces, Chris podría estar aquí interactuando con otra parte de la lava,
mientras yo juego por este lado. Pueden imaginar una nueva herramienta escultórica,
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
donde yo estoy calentando algo, volviéndolo maleable,
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
y después dejándolo enfriar y solidificándolo en un estado particular.
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 debería tener algo así en su lobby. (Risas).
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
Les mostraré algo -- un ejemplo algo más concreto, mientras esto carga.
02:41
as this thing loads.
47
137296
1333
Ésta es una caja de luz para fotógrafos.
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
De nuevo, puedo usar mis dos manos para interactuar y mover las fotos.
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
Pero lo que es aún más genial es que si uso dos dedos,
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
puedo agarrar una foto y estirarla de esta manera con mucha facilidad.
Puedo moverla, acercarla y girarla sin esfuerzo.
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
Puedo hacer eso con ambas manos,
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
o puedo hacerlo sólo con dos dedos de cada una de mis manos.
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
Si tomo el lienzo, puedo hacer más o menos lo mismo -- estirarlo.
Puedo hacerlo simultáneamente, lo sostengo
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
y agarro otro, estirándolo de esta manera.
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
De nuevo, la interfaz simplemente desaparece.
03:14
Again, the interface just disappears here.
58
170286
2228
No hay manual. Esto es exactamente lo que esperarían,
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
especialmente si no han interactuado con un computador antes.
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
Ahora, cuando existen iniciativas como el computador portátil de 100 dólares,
03:25
I kind of cringe at the idea
63
181728
1533
Me estremezco con la idea de introducir a toda una nueva generación
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
de personas a la computación con la interfaz estándar de ratón y ventanas.
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
Yo pienso que esta es la manera en la que deberíamos interactuar con las máquinas
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
desde este momento. (Aplausos)
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
Ahora, por supuesto, puedo sacar un teclado.
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
Puedo moverlo, ponerlo allá arriba.
03:55
Obviously, this is a standard keyboard,
72
211213
1858
Obviamente, esta es una especie de teclado estándar,
pero por supuesto, puedo escalarlo para que funcione bien con mis manos.
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
Y eso es bastante importante, porque no hay ninguna razón en estos días por la que
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
debamos estar confinados a un dispositivo físico.
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
Eso lleva a cosas malas, como LER. (Lesiones por Esfuerzo Repetitivo)
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
Tenemos tanta tecnología estos días que
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
las interfaces deben empezar a adaptarse a nosotros.
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
Se ha invertido tan poco en mejorar
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
la manera en la que interactuamos con las interfaces.
Lo más probable es que este teclado sea en realidad la dirección incorrecta para continuar.
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
Pueden imaginar, en el futuro, a medida que desarrollamos este tipo de tecnología,
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
un teclado que siga su mano mientras se aleja,
y anticipe inteligentemente qué tecla están tratando de presionar.
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
¿No es esto genial?
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
Audiencia: ¿Donde está tu laboratorio?
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: Soy un investigador de la Universidad de Nueva York (NYU).
Aca hay un ejemplo de otro tipo de aplicación. Puedo crear estas pelotitas.
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
La aplicación recordará los trazos que realizo. Desde luego, puedo hacerlo con ambas manos.
04:55
Of course I can do it with all my hands.
91
271358
1919
Es sensible a la presión, como notarán.
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
Pero lo entretenido es, nuevamente, que como les mostré antes, con un gesto de dos dedos puedo
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
hacer zoom rápidamente. No tienen que cambiar a otra herramienta
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
o usar una herramienta de lupa;
05:06
or the magnifying glass tool,
96
282705
1406
pueden hacer cosas continuamente en múltiples escalas reales, todo al mismo tiempo.
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
Puedo crear cosas grandes, pero puedo volver rápidamente a
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
donde comencé, y hacer cosas aún más pequeñas.
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
Ahora, esto será muy importante a medida que nos involucremos con cosas como
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
la visualización de datos. Por ejemplo, creo que todos disfrutamos la charla de 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
y él puso mucho énfasis en algo en lo que he estado pensando por mucho tiempo:
tenemos todos estos datos geniales, pero por alguna razón, simplemente están ahí.
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
No los estamos usando. Y creo que una de las razones, es porque
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
-- tendremos el apoyo de cosas como gráficas y herramientas de visualización e inferencia.
Pero pienso que una gran parte de eso será comenzar a contar con mejores interfaces,
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
para poder acceder a este tipo de información, sin dejar de pensar en el panorama global.
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
Déjenme mostrarles otra aplicación. Esta se llama WorldWind.
Es desarrollada por NASA. Es un tipo de -- todos hemos visto Google Earth;
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
esta es una versión de código abierto de eso mismo. Hay plug-ins que permiten
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
cargar distintos conjuntos de datos que NASA ha recolectado durante años.
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
Pero como pueden ver, puedo usar los mismos gestos con dos dedos
para bajar y acercarme a la perfección. De nuevo, no hay una interfaz.
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
Realmente permite que cualquiera se acerque -- y, hace justamente lo que esperas que haga,
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
Nuevamente, acá no hay una interfaz. La interfaz desaparece.
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
Puedo cambiar a diferentes vistas de datos. Eso es lo genial de esta aplicación.
06:28
That's what's neat about this app here.
128
364900
2194
Ahí lo tienen. NASA es genial. Tienen estas imágenes hiper-espectrales
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
que están falsamente coloreadas para que puedan -- es muy útil para determinar el uso vegetativo. Bueno, volvamos.
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
Ahora, lo mejor de las aplicaciones de cartografía --
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
no es el 2D, es el 3D. Entonces, nuevamente, con una interfaz multi-punto
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
pueden hacer un gesto como este -- para que puedan inclinar la cámara,
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
No está relegada al movimiento y al paneo 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

Ahora, este gesto que hemos desarrollado, funciona colocando dos dedos en la superficie,
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
definiendo un eje de inclinación, y puedo inclinar arriba y abajo de esa forma.
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
Fue algo que se nos ocurrió en el momento,
07:06
We just came up with that on the spot,
141
402441
2078
y probablemente no sea lo correcto,
07:08
it's probably not the right thing to do,
142
404543
1937
pero hay tantas cosas interesantes que se pueden hacer con este tipo de interfaz.
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
Es muy entretenido jugar con ella también. (Risas)
07:17
(Laughter)
145
413958
1353
Y lo último que quería mostrarles --
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
Estoy seguro que todos podemos pensar en muchas aplicaciones de entretenimiento
que se pueden hacer con esto.
07:24
that you can do with this thing.
148
420701
1524
Estoy algo más interesado en el tipo de aplicaciones creativas que se pueden hacer.
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
Aquí hay una aplicación muy simple -- Puedo dibujar una curva.
07:30
Now, here's a simple application here --
I can draw out a curve.
I can draw out a curve.
150
426323
3237
Y cuando la cierro, se convierte en un personaje.
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
Pero lo genial, es que puedo añadir puntos 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
Y lo que puedo hacer es manipularlos con mis dos dedos al mismo tiempo.
07:45
And you notice what it does.
154
441787
1903
Y se pueden dar cuenta de lo que hace.
07:48
It's kind of a puppeteering thing,
155
444253
2555
Es como una marioneta, donde puedo usar
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
cuantos dedos tenga para dibujar y hacer --
Ahora, hay un montón de matemáticas tras esto
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
para que controle este objeto correctamente.
Lo que quiero decir, es que esta técnica que permite manipular este objeto,
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
con múltiples puntos de control, es algo totalmente nuevo.
08:15
is actually state of the art.
160
471899
1476
Fue publicado en Siggraph recién el año pasado,
08:17
It was released at SIGGRAPH last year.
161
473399
1824
pero es un gran ejemplo del tipo de investigación que me encanta.
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
Todo este poder computacional aplicado a hacer que las cosas hagan las cosas correctas,
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
cosas intuitivas. Hacer exactamente lo que esperas.
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
Bueno, la interaccion multi-táctil es un campo muy activo ahora en la IPC (Interacción persona-computador)
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
No soy el único haciéndolo, hay muchas personas investigando.
Este tipo de tecnología va a permitir que aún más gente se interese,
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
y estoy muy ansioso de interactuar con todos ustedes
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
en los próximos días y ver cómo esto se puede aplicar a sus respectivos campos.
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.
