現實世界與數位資訊中間的距離正不斷地在縮短中，程式設計工程師李鎮河希望讓這個距離完全地消失。他在這場簡短卻令人嘆為觀止的演講中呈現了：一枝可以穿透螢幕在電腦中畫出 3D 模型的筆，以及一個可以透過螢幕來操控裡頭數位物件的電腦原型機。

在整個電腦的發展歷程中
00:15
we've been striving to shorten the gap between us
1
3581
3247
我們不斷地嘗試縮短
00:18
and digital information,
2
6828
1594
我們與數位資訊之間的距離
00:20
the gap between our physical world
3
8422
1834
也就是實體世界
00:22
and the world in the screen
4
10256
1798
與螢幕中虛擬世界的距離
00:24
where our imagination can go wild.
5
12054
2842
在虛擬世界裡
我們總是可以盡情發揮想像力
我們總是可以盡情發揮想像力
00:26
And this gap has become shorter,
6
14896
3927
這兩者之間的距離也確實縮短了
00:30
shorter, and even shorter,
7
18823
2765
比較近
還更再更近
還更再更近
00:33
and now this gap is shortened down
8
21588
1486
現在這個距離已經縮短到
00:35
to less than a millimeter,
9
23074
1468
不到一毫米了
00:36
the thickness of a touch-screen glass,
10
24542
1878
也就是觸控式螢幕厚度的距離
00:38
and the power of computing
11
26420
1450
任何人
00:39
has become accessible to everyone.
12
27870
4903
都可以使用電腦
00:44
But I wondered, what if there could be no boundary at all?
13
32773
5039
但我在想 有沒有可能
我們跟電腦之間變成完全零距離
我們跟電腦之間變成完全零距離
00:49
I started to imagine what this would look like.
14
37812
3744
我開始想像那會是什麼樣子
00:53
First, I created this tool
15
41556
2451
首先 我做出了這個工具
00:56
which penetrates into the digital space,
16
44007
2509
它可以穿入到數位空間裡
00:58
so when you press it hard on the screen,
17
46516
2091
所以當你用力地壓螢幕時
01:00
it transfers its physical body into pixels.
18
48607
3333
這個工具可以把你的身體
轉換成為螢幕上的像素
轉換成為螢幕上的像素
01:03
Designers can materialize their ideas
19
51940
2112
做設計的人可以
01:06
directly in 3D,
20
54052
1696
把他們的想法直接3D實體化
01:07
and surgeons can practice on virtual organs
21
55748
2552
外科醫生也可以在
01:10
underneath the screen.
22
58300
2224
螢幕中的虛擬器官上做練習
01:12
So with this tool, this boundary has been broken.
23
60524
4897
我們跟電腦之間的距離
便隨著這個工具的發明而被打破了
便隨著這個工具的發明而被打破了
01:17
But our two hands still remain outside the screen.
24
65421
2967
即使如此
我們的手還是停留在螢幕外
我們的手還是停留在螢幕外
01:20
How can you reach inside and interact
25
68388
2484
有沒有可能直接把手伸進電腦
01:22
with the digital information
26
70872
1427
透過我們靈巧的雙手
01:24
using the full dexterity of our hands?
27
72299
3004
直接使用這些數位資訊呢？
01:27
At Microsoft Applied Sciences,
28
75303
2302
我在微軟的應用科學部門裡
01:29
along with my mentor Cati Boulanger,
29
77605
1916
和著我的指導教授 Cati Boulanger
01:31
I redesigned the computer
30
79521
1271
重新設計出這台電腦
01:32
and turned a little space above the keyboard
31
80792
2881
把鍵盤上面這個小小的空間
01:35
into a digital workspace.
32
83673
2365
轉變成為一個數位化工作區
01:38
By combining a transparent display and depth cameras
33
86038
2311
是透過一個透明顯示器
跟3D距離相機的組合
跟3D距離相機的組合
01:40
for sensing your fingers and face,
34
88349
1840
去感應你的手指跟臉
01:42
now you can lift up your hands from the keyboard
35
90189
2234
於是你就可以將你的手
從鍵盤上抬起來
從鍵盤上抬起來
01:44
and reach inside this 3D space
36
92423
2914
並且就此進入3D的空間
01:47
and grab pixels with your bare hands.
37
95337
2500
並且可以直接用你的手
來抓住像素
來抓住像素
01:49
(Applause)
38
97837
2971
(鼓掌聲)
01:52
Because windows and files have a position in the real space,
39
100808
4206
因為視窗跟檔案
都在真實地存在這個空間裡
都在真實地存在這個空間裡
01:57
selecting them is as easy as grabbing a book off your shelf.
40
105014
3359
選取它們就好像
從書架上拿一本書一樣容易
從書架上拿一本書一樣容易
02:00
Then you can flip through this book
41
108373
2153
你也可以這樣翻閱這本書
02:02
while highlighting the lines, words
42
110526
1717
當要在某句話
或某些字上畫重點的時候
或某些字上畫重點的時候
02:04
on the virtual touch pad below each floating window.
43
112243
2564
就螢幕下方的觸控板上劃過去即可
02:06
Architects can stretch or rotate the models
44
114807
2535
建築師可以直接用他們的雙手
02:09
with their two hands directly.
45
117342
2425
來伸展或把模型轉過來
02:11
So in these examples,
46
119767
1620
所以在這些例子裡面
02:13
we are reaching into the digital world.
47
121387
2737
我們是真的進入了數位的世界
02:16
But how about reversing its role
48
124124
2346
還有沒有可能是相反過來
02:18
and having the digital information reach us instead?
49
126470
4819
讓數位資訊直接跑到我們面前呢
02:23
I'm sure many of us have had the experience
50
131289
1756
我相信我們當中許多人
02:25
of buying and returning items online.
51
133045
2423
都有過在網上購物或退貨的經驗
02:27
But now you don't have to worry about it.
52
135468
1793
現在你不需要再擔心了
02:29
What I got here is an online augmented fitting room.
53
137261
4822
你所看到的是一個網路實境試衣間
02:34
This is a view that you get from
54
142083
1902
當系統辨識出你的身型之後
02:35
head-mounted or see-through display
55
143985
1744
這個影像就會
02:37
when the system understands the geometry of your body.
56
145729
5147
透過頭戴式或透明顯示器穿戴在你身上
02:42
Taking this idea further, I started to think,
57
150876
3551
延伸這個想法，我開始想
02:46
instead of just seeing these pixels in our space,
58
154427
3369
有沒有可能不光是
在三度空間裡用肉眼看到像素
在三度空間裡用肉眼看到像素
02:49
how can we make it physical
59
157796
1522
而是讓像素具體化
02:51
so that we can touch and feel it?
60
159318
4262
讓我們可以摸得到
跟感覺得到它呢
跟感覺得到它呢
02:55
What would such a future look like?
61
163580
3049
這樣的未來會是什麼樣子?
02:58
At MIT Media Lab, along with my advisor Hiroshi Ishii
62
166629
3658
在麻省理工學院的媒體實驗室裡
我跟我的指導教授 Hiroshi Ishii
我跟我的指導教授 Hiroshi Ishii
03:02
and my collaborator Rehmi Post,
63
170287
2023
以及我的合作夥伴 Rehmi Post
03:04
we created this one physical pixel.
64
172310
3644
一起研發出這一個具像化的畫素
03:07
Well, in this case, this spherical magnet
65
175954
2624
這組模組中的球狀磁鐵
03:10
acts like a 3D pixel in our space,
66
178578
2352
就好像是現實生活中的3D像素
03:12
which means that both computers and people
67
180930
2904
也就是說無論是
使用電腦或人用手
使用電腦或人用手
03:15
can move this object to anywhere
68
183834
1898
都可以在這個小小的三度空間裡
03:17
within this little 3D space.
69
185732
1969
自由且同步地移動它
03:19
What we did was essentially canceling gravity
70
187701
3492
基本上我們所做的
就是拿掉重力這個因素
就是拿掉重力這個因素
03:23
and controlling the movement by combining
71
191193
2139
透過結合磁浮
03:25
magnetic levitation and mechanical actuation
72
193332
2824
及力學效應
03:28
and sensing technologies.
73
196156
2477
再加上感應技術
來讓它動起來
來讓它動起來
03:30
And by digitally programming the object,
74
198633
2505
並透過程式來將物件數位化
03:33
we are liberating the object from constraints
75
201138
2777
就讓它脫離了時間空間的限制
03:35
of time and space, which means that now,
76
203915
3435
也就是說現在
03:39
human motions can be recorded and played back
77
207350
3896
人的動作可以被紀錄並重新播放
03:43
and left permanently in the physical world.
78
211246
3619
並且在現實生活中被永久保存下來
03:46
So choreography can be taught physically over distance
79
214865
3033
所以現在芭蕾舞
也可以進行遠距教學
也可以進行遠距教學
03:49
and Michael Jordan's famous shooting can be replicated
80
217898
2525
麥可喬丹的傳奇飛人之姿
03:52
over and over as a physical reality.
81
220423
3549
也可以真實地一再重現
03:55
Students can use this as a tool
82
223972
2180
學生也可以使用它
03:58
to learn about the complex concepts
83
226152
1942
來學習像行星運動或物理學
04:00
such as planetary motion, physics,
84
228094
4084
這類比較複雜的概念
04:04
and unlike computer screens or textbooks,
85
232178
2819
相較於一般的電腦螢幕或教科書
04:06
this is a real, tangible experience
86
234997
2482
這是個有形有體的真實經驗
04:09
that you can touch and feel, and it's very powerful.
87
237479
3658
你可以觸摸跟實際感受
這會令人印象深刻
這會令人印象深刻
04:13
And what's more exciting
88
241137
1982
更令人興奮的是
04:15
than just turning what's currently in the computer physical
89
243119
3348
不是只是將電腦裡的東西實體化
04:18
is to start imagining how programming the world
90
246467
3189
而是當我們生活週遭
很多東西開始被程式化之後
很多東西開始被程式化之後
04:21
will alter even our daily physical activities.
91
249656
3696
我們的日常生活也將會隨之改變
04:27
(Laughter)
92
255460
2483
(笑聲)
04:29
As you can see, the digital information
93
257943
2756
就如各位所看到的
04:32
will not just show us something
94
260699
1518
數位資訊將不只提供知識或想法
04:34
but it will start directly acting upon us
95
262217
2110
而是直接在我們面前活生生地呈現出來
04:36
as a part of our physical surroundings
96
264327
2299
就好像是我們生活週遭的一部份
04:38
without disconnecting ourselves from our world.
97
266626
4198
我們不再需要將自己
從這個世界中抽離出來
從這個世界中抽離出來
04:42
Today, we started by talking about the boundary,
98
270824
4346
我們今天是從這層隔閡開始講起
04:47
but if we remove this boundary,
99
275170
2680
但如果這層隔閡不再復存
04:49
the only boundary left is our imagination.
100
277850
3888
那唯一會限制我們的
就只剩下自己的想像力了
就只剩下自己的想像力了
04:53
Thank you.
101
281738
1248
謝謝
04:54
(Applause)
