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
e mostrarvi una cosa pronta ad uscire dal laboratorio,
e sono molto contento che voi siate tra i primi
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,
3
7824
2472
a poterla vedere di persona. Penso davvero, infatti,
00:34
because I really think this is going
to really change
to really change
4
10320
2489
che cambierà il modo in cui interagiremo con le macchine da ora in poi.
00:36
the way we interact
with machines from this point on.

Questo é un tavolo da disegno retro-proiettato, largo circa 36 pollici,
00:39
Now, this is a rear-projected
drafting table.

6
15339
2675
00:42
It's about 36 inches wide
7
18038
1222
ed è dotato di un sensore multi touch. Ora, i sensori dei touchscreen tradizionali,
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
che trovate per esempio nei chioschi o nelle lavagne interattive,
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059
2137
registrano un solo punto di contatto alla volta.
00:49
can only register one point
of contact at a time.
of contact at a time.
11
25220
2583
Qui invece i punti di contatto possono esssere multipli.
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.
12
28137
3715
Si possono usare entrambe le mani, fare azioni coordinate,
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876
3314
e, volendo, usare tutte le dieci dita.
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
Così.
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
La tecnologia multi-touch non è completamente nuova:
Bill Buxton se ne era già occupato negli anni ’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
Tuttavia, questo prototipo ha un'alta risoluzione,
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
un basso costo, e soprattutto é molto scalabile.
01:19
So, the technology, you know,
20
55000
2337
La cosa più esaltante qui, non é tanto la tecnologia in sé,
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
quanto la facilità d'uso,
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
le cose che ci si possono fare,
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
e l'interfaccia che puoi costruirci sopra.
01:33
So let's see.
25
69141
1136
Per esempio, qui abbiamo un’applicazione della LavaLamp. Come potete vedere,
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
posso utilizzare entrambi le mani per strizzare ed unire le bolle,
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
posso "iniettare calore" qui,
01:44
I can inject heat into the system here,
29
80627
2543
posso separarle, usando due dita.
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
E' completamente intuitivo, non serve un manuale.
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
L'interfaccia scompare, in un certo senso.
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
E' nato come salvaschermo realizzato nel nostro laboratorio
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
da un nostro studente come tesi per il Ph.D., Ilva Rosemberg, ma qui dà il suo meglio, trovo.
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
Ora, una grande qualità di un sensore multi-touch è
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
la libertà di usare più dita.
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
Ma multi-touch significa, anche, multi utente.
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
Quindi Chris potrebbe lavorare con una parte di Lava
mentre io gioco con un'altra. Si potrebbe farne uno strumento di modellazione,
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
che mi permette di scaldare qualcosa per renderla malleabile,
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
e poi di raffreddarla solidificandola in una forma.
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 dovrebbe mettere qualcosa del genere, nell'atrio. (Risate)
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
Vi mostrerò qui un esempio un pò più concreto ... appena si carica.
02:41
as this thing loads.
47
137296
1333
Questa applicazione permette di manipolare una galleria d immagini.
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
Agendo con due mani, posso muovere le foto,
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
ma la cosa ancora più interessante è che, con due dita,
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
posso afferrare una foto e ingrandirla così, molto semplicemente.
La sposto, la ruoto, la giro senza sforzo.
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
Posso farlo "grossolanamente", con le due mani,
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
oppure con due dita di ciascuna mano allo stesso tempo.
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
Posso fare la stessa cosa con lo sfondo, deformandolo.
Posso farlo mentre tengo fermo questo
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
e prendendo quest'altro, contemporaneamente, deformarlo così.
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
Anche qui, l'interfaccia non interferisce,
03:14
Again, the interface just disappears here.
58
170286
2228
Non c'é bisogno di manuali, fa esattamente quello che uno si aspetta che faccia,
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
specialmente se l'utente è un neofita.
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
Ora, quando penso al laptop da 100 $,
03:25
I kind of cringe at the idea
63
181728
1533
tremo al pensiero che una nuova generazione di utenti
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
si abitui ad interfacce di mouse e finestre.
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
Trovo sia questo il modo di interagire con le macchine da adottare (Applausi)
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
da ora in poi (Applausi)
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
Naturalmente, posso far apparire una tastiera,
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
spostarla, lasciarla qui.
03:55
Obviously, this is a standard keyboard,
72
211213
1858
E' una tastiera standard,
ma posso adattarla alle dimensioni delle mie mani.
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
Il che é fondamentale. Non si capisce, infatti, perchè ancora oggi
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
ci si debba adattare alle dimensioni di un oggetto fisico,
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
con tutti i problemi, come la RSI (danno da sforzo prolungato), che ne derivano.
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
Con tutta la tecnologia che abbiamo, sono le interfacce fisiche
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
che dovrebbero adeguarsi a noi (e non viceversa).
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
Ma si sta lavorando davvero poco
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
sul modo in cui interagiamo con le interfacce.
La tastiera tradizionale é probabilmente il modo sbagliato di procedere.
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
Sviluppando la nostra tecnologia si può immaginare, in futuro,
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
una tastiera mobile che segue le dita,
anticipando quale sia il prossimo tasto usato,
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
Quindi ... non è fantastico?
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
Pubblico: Dov'é il tuo 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: - Sono un ricercatore alla New York University.
Questa é un'altra applicazione. Posso creare puntini animati.
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
il programma ricorda l'operazione precedente, e naturalmente posso farlo con tutte e due le mani.
04:55
Of course I can do it with all my hands.
91
271358
1919
Notate che è sensibile alla pressione.
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
ma la cosa più bella è che posso zoomare con due dita,
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
con rapidità. Non serve selezionare uno strumento
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
o una lente di ingrandimento,
05:06
or the magnifying glass tool,
96
282705
1406
e si può operare a scale diverse contemporaneamente.
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
Posso "allontanarmi" e creare oggetti grandi, qui, e poi
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
"avvicinarmi", e fare oggetti anche più piccoli, di qua.
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
Questo sarà molto importante in campi come la visualizzazione dei dati.
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
Abbiamo certamente apprezzato la conferenza di 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
e la sua enfasi su una cosa cui anch'io ho pensato a lungo:
abbiamo una mole enorme di dati, ma sono "fermi",
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
non vi possiamo accedere perchè, credo ...
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
in futuro saremo aiutati da strumenti di rappresentazione grafica e di estrapolazione.
Ma un grande contributo verrà anche da interfacce migliori che permettano
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
di analizzare i dettagli "in basso", senza perdere il quadro generale "in alto".
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
Adesso vi mostro un'altra applicazione. Si chiama World Wind,
é un programma della NASA. Conoscete Google Earth?
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
E' una versione Open Source di Google Earth. Ci sono dei plug-in per
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
caricare i dati raccolti dalla NASA nel corso degli anni.
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
E anche qui, posso zoomare, spostarmi con due dita,
entrare ed uscire senza fatica. Ancora una volta, l'interfaccia non si vede
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
Chiunque può entrare e fare quello che si aspetta,
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
l'interfaccia è trasparente.
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
Posso spostarmi tra visualizzazioni diverse, e questo è il bello di questa applicazione.
06:28
That's what's neat about this app here.
128
364900
2194
Ecco. Il bello della NASA è che usa immagini iperspettrali,
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
falsamente colorate, ottime per studiare la vegetazione. E ora, torniamo indietro.
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

Una cosa bella delle applicazioni di mappatura
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
è che sono in 3D, non in 2D. E quindi, un'interfaccia multipunto
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
ci permette di inclinare la prospettiva con questo semplice gesto.
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
Non siamo limitati ad ingrandimenti e movimenti in 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

Qui abbiamo sviluppato un asse di rotazione definibile con due dita
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
attorno a cui effettuare la rotazione, così.
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
Un'invezione fatta quasi per caso,
07:06
We just came up with that on the spot,
141
402441
2078
e forse non é nemmeno giusta
07:08
it's probably not the right thing to do,
142
404543
1937
ma dà l'idea di quanto questa interfaccia sia interessante,
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 persino divertente da usare (Risate).
07:17
(Laughter)
145
413958
1353
Per finire, l'ultima cosa che voglio mostrarvi ...
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
a tutti verranno senz'altro in mente applicazioni divertenti
per questa tecnologia.
07:24
that you can do with this thing.
148
420701
1524
Ma io sono più interessato alle applicazioni creative realizzabili con questa tecnologia.
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
Guardate questa. Posso tracciare 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
Quando la chiudo, diventa un personaggio.
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
E il bello è che posso aggiungere i "punti di controllo",
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
naturalmente con più dita, contemporaneamente.
07:45
And you notice what it does.
154
441787
1903
Come potete notare,
07:48
It's kind of a puppeteering thing,
155
444253
2555
posso diventare un burattinaio
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
usando tutte le dieci dita.
E' necessaria molta matematica
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
per controllare questo "gioco", e fargli fare la cosa "giusta".
La manipolazione della forma mantenendo fermi
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
i punti di controllo, richiede una tecnologia allo stato dell'arte.
08:15
is actually state of the art.
160
471899
1476
Sono cose uscite dal Siggraph dell'anno scorso.
08:17
It was released at SIGGRAPH last year.
161
473399
1824
Ma sono un grande esempio del tipo di ricerca che amo.
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
Usare la potenza di calcolo perché il computer faccia le cose "giuste",
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
in modo intuitivo, come uno se le aspetta.
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
La ricerca sull'interazione multi-touch è un campo molto attivo, nell'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
Siamo in tanti a lavorarci, ed altri stanno arrivando.
E questa tecnologia attirerà ancora altra gente.
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
E non vedo l'ora di parlare con tutti 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
nei prossimi giorni, per studiare come utilizzarla nel vostro settore.
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.
