我真的，真的非常興奮，今天能夠在這邊，
00:24
I'm really excited to be here today.

00:25
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
因為，我將要向你們展示一些，剛剛完成研發的技術，
真的，而且我非常高興，你們能夠成為世界上，親眼目睹這個技術，最早的一群人之一，
00:29
literally, and I'm really glad
that you guys
that you guys
2
5024
2776
00:31
are going to be among
the first to see it in person,
the first to see it in person,
3
7824
2472
因為我真的，真的認為這將會改變，
00:34
because I really think this is going
to really change
to really change
4
10320
2489
真真正正的改變，從今以後我們與機器互動的方式。
00:36
the way we interact
with machines from this point on.
with machines from this point on.

現在，這邊有一個背投影式繪圖桌。它大概有 36 吋寬，
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
而且它配備有多點觸控感應器。平日所見的一般觸控感應器，
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
像是自動櫃台，或是互動式白板，
00:47
like on a kiosk
or interactive whiteboards,
or interactive whiteboards,
10
23059
2137
在同一時間，只能辨識一個接觸點。
00:49
can only register one point
of contact at a time.
of contact at a time.
11
25220
2583
而這東西，能允許你同時間，具有多點控制。
00:52
This thing allows you to have
multiple points at the same time.
multiple points at the same time.
12
28137
3715
這些觸控點，可以是從我的雙手而來，我可以單手使用多指，
00:55
They can use both my hands;
I can use chording actions;
I can use chording actions;
13
31876
3314
或者，如果我想要，我可以一次使用全部十根手指。
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
你知道的，就像這樣。
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
雖然多點觸控不是全然嶄新的概念。
我是說，像是著名的 Bill Buxton 早在 80 年代就已經開始嘗試這個概念。
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
然而，我在這裡所建造的這個方法，是具有高解析度、
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
低價，並且也許最重要的是，其硬體可以非常簡單的調整尺寸。
01:19
So, the technology, you know,
20
55000
2337
因此，這個技術，如我所言，並不是現在你所見到，最令人興奮的東西，
01:21
isn't the most exciting thing
here right now,
here right now,
21
57361
2446
可能除了它與眾不同的低價位以外。
01:23
other than probably
its newfound accessibility.
its newfound accessibility.
22
59831
2318
這邊真正令人感興趣的是，你能夠用它來做什麼事？
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
以及你將能夠利用它，所創造出來的介面。現在讓我們來看看。
01:33
So let's see.
25
69141
1136
舉例來說，這邊我們有一個岩漿燈軟體。你可以看到，
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
我可以使用我的雙手，將這些斑點經由擠壓，而使它們變成一團。
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
我可以像這樣將系統加熱，
01:44
I can inject heat into the system here,
29
80627
2543
或者我可以用我的兩跟手指，將它們分開。
01:47
or I can pull it apart
with two of my fingers.
with two of my fingers.
30
83194
2182
這是完全直覺性的操作，你將不會需要使用手冊。
01:49
It's completely intuitive;
there's no instruction manual.
there's no instruction manual.
31
85400
2730
操控介面似乎就這樣憑空消失了。
01:52
The interface just kind of disappears.
32
88154
1822
01:54
This started out as a screensaver app
33
90000
1920
這一開始，是我們實驗室的一個博士班學生，所創造的一個類似螢幕保護程式的軟體
01:55
that one of the Ph.D. students
in our lab, Ilya Rosenberg, made.
in our lab, Ilya Rosenberg, made.
34
91944
3047
他的名字叫做 Ilya Rosenberg. 但是我認為，這個軟體真正的價值，在這邊顯現了。
01:59
But I think its true identity
comes out here.
comes out here.
35
95015
4021
多點觸控感應器厲害的地方在這邊，像這樣，
02:04
Now what's great about a multi-touch
sensor is that, you know,
sensor is that, you know,
36
100153
2923
我可以使用許多手指來操控這個，
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
但是當然，多點觸控本質上也意味著多使用者。
02:12
Chris could be interacting
with another part of Lava,
with another part of Lava,
39
108863
2499
所以克里斯 (Chris) 可以到台上來，與岩漿的另一部份互動，
在此同時，我在這邊玩弄這一部份。你可以將之想像為一種新的雕塑工具，
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
在這邊我將部份加熱，增加它的可塑性，
02:19
where I'm kind of warming something up,
making it malleable,
making it malleable,
42
115164
2979
然後讓它冷卻、硬化到某個程度。
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
谷歌 (Google) 在他們大廳應該要有個像這樣的東西。（笑聲）
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
我將要向你們展示某樣東西，一個比較實際的應用範例，等它載入完成。
02:41
as this thing loads.
47
137296
1333
這是一個攝影師的燈箱工具應用程式。
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
再一次地，我可以使用我的兩隻手，來與這些照片互動並移動它們。
02:49
But what's even cooler
is that if I have two fingers,
is that if I have two fingers,
50
145923
3555
但是更酷的是，如果我用兩跟手指，
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
事實上我可以抓取一張照片，並且非常簡單的將之放大，就像這樣。
我可以任意地拖移、縮放並旋轉這張照片。
02:57
I can pan, zoom
and rotate it effortlessly.
and rotate it effortlessly.
52
153656
3466
我可以使用我的雙手掌來這樣做，
03:01
I can do that grossly
with both of my hands,
with both of my hands,
53
157146
2331
或者，我可以只用我任何一隻手的兩隻手指一起來完成。
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
如果我抓住整個畫板，我可以做同樣的事，將之放大。
我可以同時操作，現在我一邊抓住這個不放，
03:09
I can do it simultaneously,
holding this down,
holding this down,
56
165780
2159
然後握住另外一張，把它像這樣放大。
03:11
and gripping on another one,
stretching this out.
stretching this out.
57
167963
2299
同樣的，在這裡我們也看不到操控介面。
03:14
Again, the interface just disappears here.
58
170286
2228
不需要說明書。它的操作結果完全如你所預期，
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
特別是如果你以前沒有接觸過電腦的話。
03:23
Now, when you have initiatives
like the $100 laptop,
like the $100 laptop,
62
179000
2704
現在，如果你想創造一個事業，像是一百美元的筆電，
03:25
I kind of cringe at the idea
63
181728
1533
其實，我對於我們將要向一個全新世代的族群介紹
03:27
of introducing a whole new
generation to computing
generation to computing
64
183285
2577
傳統電腦的視窗滑鼠點擊介面這個想法，有所保留。
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
多點觸控才是我認為從今爾後，我們所應該與機器互動的真正方法。（掌聲）
03:35
we should be interacting
with machines from now on.
with machines from now on.
67
191808
2641
多點觸控才是我認為從今爾後，我們所應該與機器互動的真正方法。（掌聲）
03:38
(Applause)
68
194473
6503
03:45
Now, of course, I can bring up a keyboard.
69
201000
2000
當然，我可以在這邊叫出鍵盤。
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
我可以將我打的字帶出來，將之放在這邊。
03:55
Obviously, this is a standard keyboard,
72
211213
1858
很明顯的，這與一般標準鍵盤並無不同，
但是當然，我可以重新縮放這個鍵盤的大小，讓它適合我的雙手使用。
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
這是非常重要的，因為在今日的科技下，沒有理由
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
我們應該去適應物理性的裝置。
04:03
that we should be conforming
to a physical device.
to a physical device.
75
219558
2340
那將會導致不好的後果，例如：重複性勞損。
04:05
That leads to bad things, like RSI.
76
221922
1747
04:07
We have so much technology nowadays
77
223693
2777
今日我們有許多這麼好的科技，
04:10
that these interfaces
should start conforming to us.
should start conforming to us.
78
226494
4029
這些操控介面應該開始來適應我們。
04:14
There's so little applied now
to actually improving
to actually improving
79
230547
3977
直到今日，真正改善我們與介面互動的應用還太少。
04:18
the way we interact with interfaces
from this point on.
from this point on.
80
234548
2579
直到今日，真正改善我們與介面互動的應用還太少。
這個虛擬鍵盤，事實上可能是一個錯誤的發展方向。
04:21
This keyboard is probably actually
the really wrong direction to go.
the really wrong direction to go.
81
237151
3191
你可以想像，在未來，當我們開始發展這種技術之後，
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
一個鍵盤，當你移開手的時候，也會自動漂移開來，
而且會非常聰明地預測，你將要用你的手打擊那一顆按鍵。
04:31
and really intelligently anticipates
which key you're trying to stroke.
which key you're trying to stroke.
84
247119
3515
因此～ 再問一次，很棒吧？
04:35
So -- again, isn't this great?
85
251477
2293
04:39
(Laughter)
86
255051
1972
聽眾：你的實驗室在哪裡？
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
韓傑夫：我是紐約市紐約大學的研究科學家。
這是另一種應用程式的範例。我可以創造出這些小毛球。
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
它會記憶我所做過的點擊。當然，我可以使用兩手操作。
04:55
Of course I can do it with all my hands.
91
271358
1919
你會注意到，它具有壓感功能。
04:57
It's pressure-sensitive.
92
273301
1291
04:59
What's neat about that is,
93
275905
1556
但是，真正棒的在這邊，我已經向你們示範過兩指操控手勢，
05:01
I showed that two-finger gesture
that zooms in really quickly.
that zooms in really quickly.
94
277485
2965
它能夠讓你很快的放大。因為你不需要事先切換到手掌工具
05:04
Because you don't have
to switch to a hand tool
to switch to a hand tool
95
280474
2207
或者放大鏡工具;
05:06
or the magnifying glass tool,
96
282705
1406
你可以連續地在多個不同的比例上，即時的創造東西，一次完成。
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
我可以在這邊建造大東西，我也可以回去，非常迅速的回去
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
回到我一開始的地方，然後甚至在這邊建造更小的東西。
05:17
to where I started,
and make even smaller things here.
and make even smaller things here.
101
293235
2700
這將會變得非常重要，當我們一旦開始從事像是
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
資料視覺化的工作。舉例來說，我想我們都非常喜歡 Hans Rosling 的演說，
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
而且他真正的，著重在強調一個我也已經思考許久的事實，
我們都擁有這些了不起的資料，但是，基於某些原因，它們只是被擺在那邊。
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
我們並沒有真正的去使用它。我認為其中一個原因就是，
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
藉由圖像、視覺化和參考工具，可以幫助我們處理這些資料。
但是，很大的一部分，我也著重在開始能夠創建更好的使用者介面，
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
能夠鑽研深入像這樣的資料，但同時仍能保持對整體的宏觀性。
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
現在，讓我向你們展示另一個應用程式。這個程式叫做「世界風」。
是太空總署 (NASA) 所研發的。它就像我們都見過的谷歌地球 (Google Earth);
05:57
It's done by NASA.
116
333463
1139
05:58
We've all seen Google Earth;
117
334626
2830
這就好像是它的開源碼版本。有附加檔能夠載入
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
太空總署經年蒐集的各種資料集。
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
但是，如你所見，我可以使用同樣的兩指手勢
非常迅速的下潛、進入地球。又一次的，我們看不到操控介面的存在。
06:11
to go down and go in really seamlessly.
122
347477
2482
06:13
There's no interface, again.
123
349983
1380
這真的能讓所有人，感覺非常地融入那個環境，而且操作就如同你所預期一般，
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
你能體會嗎？再一次，在這邊你看不到操作介面。介面就這樣消失了。
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
我可以切換到不同的資料瀏覽。這就是這個應用程式厲害的地方。
06:28
That's what's neat about this app here.
128
364900
2194
就像這樣。太空總署非常的酷。它們有這些超光譜影像
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
這些影像是人工成色的，對於決定植物的繁茂程度非常有幫助。讓我們回到剛剛那裡。
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
地圖軟體的偉大之處在於，
06:44
The great thing
about mapping applications --
about mapping applications --
133
380312
2174
它不只是 2D 平面，它也可以是 3D 立體影像。所以再一次，應用多點觸控介面，
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
你可以使用像這樣的手勢，所以你可以使畫面像這樣傾斜，
06:51
so you can be able
to tilt around like that --
to tilt around like that --
136
387540
3437
你知道。不只是受限於簡單的 2D 平面攀移與移動。
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
我們已經研發出了這些手勢，像這樣，只要放入你的兩跟手指，
07:00
This gesture is just putting
two fingers down --
two fingers down --
139
396105
2635
它界定了傾斜的軸線，如此這般我就可以向上或向下任意傾斜。
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
這是我們在這邊，剛剛想出來的點子，
07:06
We just came up with that on the spot,
141
402441
2078
你知道嗎？也許這不是這樣做最好的方法，
07:08
it's probably not the right thing to do,
142
404543
1937
但是使用這種介面，你可以做許多很有趣的事情。
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
就算你什麼都不做，只是玩玩，也會感覺愉快。（笑聲）
07:17
(Laughter)
145
413958
1353
所以，最後一件我想要向你們展示的東西是，
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
你知道，我確信我們都可以想到很多，你可以利用這個東西所做的
娛樂方面的應用。
07:24
that you can do with this thing.
148
420701
1524
我對於我們可以利用這東西，所做的創意性應用更感興趣。
07:26
I'm more interested in the creative
applications we can do with this.
applications we can do with this.
149
422249
4050
現在，這邊有一個簡單的程式，我可以畫曲線。
07:30
Now, here's a simple application here --
I can draw out a curve.
I can draw out a curve.
150
426323
3237
當我將曲線封閉起來的時候，它就變成一個人偶。
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
但是有趣的事情是，我可以增加控制點。
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
然後我可以用我雙手的手指同時操控它們。
07:45
And you notice what it does.
154
441787
1903
你會注意到它是怎麼做的。
07:48
It's kind of a puppeteering thing,
155
444253
2555
這就像是操控木偶一般，這邊我可以使用
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
我的十跟手指去畫出並做出玩偶。
事實上，在這表象之下需要很多數學運算，
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
然後它才能控制這些圖案，並正確的反應。
我的意思是，在這邊這個能夠操控圖案的技術，
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
並使用多個操控點，事實上是屬於一種尖端科技。
08:15
is actually state of the art.
160
471899
1476
這個技術去年才在計算機圖形學會議上公開，
08:17
It was released at SIGGRAPH last year.
161
473399
1824
但這是我真正喜好研究領域的良好範例。
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
所有這些需要使事情做「對」，背後的電腦運算。
08:22
all this compute power
to make things do the right things,
to make things do the right things,
163
478041
2799
直覺性的事情。做如你所預期一模一樣的事。
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
多點觸控互動研究，現在在人機介面領域非常地活躍。
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
我不是唯一一個在做這方面研究的，還有很多其他的人也在這領域。
而這種技術，將會讓更多人加入這個領域的研究，
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
我真的非常期待，跟在場各位接下來幾天的互動
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
看看這技術，將能如何應用在你們所處的領域。
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.
