我们的现实世界和数字虚拟世界之间的边界已经变得越来越窄。李镇河是一名设计师兼工程师。他想让这两个世界完全溶和。在他简短而让人惊叹的演讲中，他做了如下演示来阐释他的想法：一支可以穿透屏幕画出三维立体模型的笔、一个能让你将双手伸进屏幕去操作数字对象的计算机桌面原型。

纵观计算机中的历史
00:15
we've been striving to shorten the gap between us
1
3581
3247
我们一直在努力弥合
00:18
and digital information,
2
6828
1594
我们与数字信息之间的隔阂，
00:20
the gap between our physical world
3
8422
1834
还有我们的现实世界
00:22
and the world in the screen
4
10256
1798
与虚拟世界之间的差距。
00:24
where our imagination can go wild.
5
12054
2842
在虚拟世界里，我们的想象力是无穷的。
00:26
And this gap has become shorter,
6
14896
3927
这一差距已经在缩短，
00:30
shorter, and even shorter,
7
18823
2765
还会继续缩短，
00:33
and now this gap is shortened down
8
21588
1486
现在这一差距已经缩短到
00:35
to less than a millimeter,
9
23074
1468
小于一毫米，
00:36
the thickness of a touch-screen glass,
10
24542
1878
就是触摸屏的玻璃那么薄，
00:38
and the power of computing
11
26420
1450
而且计算机已是
00:39
has become accessible to everyone.
12
27870
4903
人皆有之。
00:44
But I wondered, what if there could be no boundary at all?
13
32773
5039
但我在想，要是没有虚拟和现实世界之间的边界该多好?
00:49
I started to imagine what this would look like.
14
37812
3744
我于是就开始大胆尝试这个想法。
00:53
First, I created this tool
15
41556
2451
我首先造出了这个工具，
00:56
which penetrates into the digital space,
16
44007
2509
它可以深入数字空间，
00:58
so when you press it hard on the screen,
17
46516
2091
如果你拿这支笔用力按这个屏幕，
01:00
it transfers its physical body into pixels.
18
48607
3333
这支笔的笔身就会进到由像素点组成的虚拟世界中。
01:03
Designers can materialize their ideas
19
51940
2112
设计师们可以直接在三维立体空间内
01:06
directly in 3D,
20
54052
1696
实现他们的想法，
01:07
and surgeons can practice on virtual organs
21
55748
2552
外科医生可以在屏幕里面
01:10
underneath the screen.
22
58300
2224
练习给虚拟器官动手术。
01:12
So with this tool, this boundary has been broken.
23
60524
4897
可见，这个工具打破了虚拟和现实世界之间的边界。
01:17
But our two hands still remain outside the screen.
24
65421
2967
但我们双手还是在屏幕外。
01:20
How can you reach inside and interact
25
68388
2484
我们怎样才能把手伸进去
01:22
with the digital information
26
70872
1427
和数字信息进行交互，
01:24
using the full dexterity of our hands?
27
72299
3004
从而充分利用我们灵活的双手？
01:27
At Microsoft Applied Sciences,
28
75303
2302
我在微软应用科学实验室，
01:29
along with my mentor Cati Boulanger,
29
77605
1916
和我的导师卡迪•布兰葛
01:31
I redesigned the computer
30
79521
1271
重新设计了这台计算机
01:32
and turned a little space above the keyboard
31
80792
2881
把键盘上方的小空间
01:35
into a digital workspace.
32
83673
2365
挪进数字工作区内。
01:38
By combining a transparent display and depth cameras
33
86038
2311
通过将一个透明显示屏与几个深度摄像头结合，
01:40
for sensing your fingers and face,
34
88349
1840
这几个摄像头可以感知你的手指和脸，
01:42
now you can lift up your hands from the keyboard
35
90189
2234
现在你可以从键盘上抬起你的双手
01:44
and reach inside this 3D space
36
92423
2914
伸进这个三维立体空间去
01:47
and grab pixels with your bare hands.
37
95337
2500
徒手控制里面的虚拟物质——像素点。
01:49
(Applause)
38
97837
2971
（掌声）
01:52
Because windows and files have a position in the real space,
39
100808
4206
因为窗口和文件在现实空间内有了具体位置，
01:57
selecting them is as easy as grabbing a book off your shelf.
40
105014
3359
选取它们变得像从书架上拿一本书那么容易。
02:00
Then you can flip through this book
41
108373
2153
然后你可以翻阅这本书
02:02
while highlighting the lines, words
42
110526
1717
并在每个浮动窗口下面的虚拟触控板上
02:04
on the virtual touch pad below each floating window.
43
112243
2564
划出字词和句子。
02:06
Architects can stretch or rotate the models
44
114807
2535
建筑师们可以直接用他们的双手
02:09
with their two hands directly.
45
117342
2425
拉伸或旋转各种模型。
02:11
So in these examples,
46
119767
1620
在这些例子表明，
02:13
we are reaching into the digital world.
47
121387
2737
我们正在进入数字世界。
02:16
But how about reversing its role
48
124124
2346
可是如何才能转变它的角色
02:18
and having the digital information reach us instead?
49
126470
4819
从而让数字信息进入我们的世界中？
02:23
I'm sure many of us have had the experience
50
131289
1756
相信在座很多人都有
02:25
of buying and returning items online.
51
133045
2423
在线购物和退货的经验。
02:27
But now you don't have to worry about it.
52
135468
1793
不过，现在你不比再担心。
02:29
What I got here is an online augmented fitting room.
53
137261
4822
因为，我这里有个增强版在线试衣间。
02:34
This is a view that you get from
54
142083
1902
这是这个系统分析了我们身体的几何特征后，
02:35
head-mounted or see-through display
55
143985
1744
通过头载式或透视式显示方式
02:37
when the system understands the geometry of your body.
56
145729
5147
展示给我们看的情形。
02:42
Taking this idea further, I started to think,
57
150876
3551
不过，我又开始进一步思考这一想法，
02:46
instead of just seeing these pixels in our space,
58
154427
3369
怎样才能让我们空间里的这些可见的像素点
02:49
how can we make it physical
59
157796
1522
转变为实实在在
02:51
so that we can touch and feel it?
60
159318
4262
能摸得到、感觉到的物质？
02:55
What would such a future look like?
61
163580
3049
这种未来会是什么样子的？
02:58
At MIT Media Lab, along with my advisor Hiroshi Ishii
62
166629
3658
在麻省理工学院媒体实验室里，我和我的导师石井裕
03:02
and my collaborator Rehmi Post,
63
170287
2023
还有我的搭档雷米·波斯特，
03:04
we created this one physical pixel.
64
172310
3644
共同研制出这一“物质像素点”。
03:07
Well, in this case, this spherical magnet
65
175954
2624
在这种情况下，这个球形磁体
03:10
acts like a 3D pixel in our space,
66
178578
2352
就好像是我们空间中的一个三维像素点，
03:12
which means that both computers and people
67
180930
2904
这就意味着计算机和人
03:15
can move this object to anywhere
68
183834
1898
可以将这个物体移动到
03:17
within this little 3D space.
69
185732
1969
这一三维立体小空间的任何位置。
03:19
What we did was essentially canceling gravity
70
187701
3492
我们的基本实现原理是，消除重力对小球的作用
03:23
and controlling the movement by combining
71
191193
2139
并通过磁悬浮、机械驱动
03:25
magnetic levitation and mechanical actuation
72
193332
2824
和传感技术的结合
03:28
and sensing technologies.
73
196156
2477
来控制小球的运动。
03:30
And by digitally programming the object,
74
198633
2505
通过对这个对象的数字编程，
03:33
we are liberating the object from constraints
75
201138
2777
我们正试着解放
03:35
of time and space, which means that now,
76
203915
3435
时间和空间对物质的限制，这意味着，现在，
03:39
human motions can be recorded and played back
77
207350
3896
人的运动可以在物质世界中可以被
03:43
and left permanently in the physical world.
78
211246
3619
录制、重放和永久保留。
03:46
So choreography can be taught physically over distance
79
214865
3033
这样，舞蹈编排就可以被远程而且真实地传授，
03:49
and Michael Jordan's famous shooting can be replicated
80
217898
2525
迈克尔·乔丹著名的扣篮动作就可以
03:52
over and over as a physical reality.
81
220423
3549
反反复复、实实在在地被重演。
03:55
Students can use this as a tool
82
223972
2180
学生可以把它当作一种工具
03:58
to learn about the complex concepts
83
226152
1942
去学习那些复杂的概念
04:00
such as planetary motion, physics,
84
228094
4084
比如行星运动、物理，
04:04
and unlike computer screens or textbooks,
85
232178
2819
而且不同于电脑屏幕或教科书的是，
04:06
this is a real, tangible experience
86
234997
2482
这种学习过程是真实存在的
04:09
that you can touch and feel, and it's very powerful.
87
237479
3658
你可以触摸它、感觉它，很给力！
04:13
And what's more exciting
88
241137
1982
更令人兴奋的是，
04:15
than just turning what's currently in the computer physical
89
243119
3348
这不止是把当前计算机的东西转变为真实的物质，
04:18
is to start imagining how programming the world
90
246467
3189
而是开始想象，编程的世界甚至将
04:21
will alter even our daily physical activities.
91
249656
3696
改变我们日常的体能活动。
04:27
(Laughter)
92
255460
2483
（笑声）
04:29
As you can see, the digital information
93
257943
2756
如您所见，数字信息
04:32
will not just show us something
94
260699
1518
将不仅仅是把东西显示给我们
04:34
but it will start directly acting upon us
95
262217
2110
而是将开始直接作用于我们
04:36
as a part of our physical surroundings
96
264327
2299
成为我们现实环境的一部分
04:38
without disconnecting ourselves from our world.
97
266626
4198
并非切断我们与现实世界的联系。
04:42
Today, we started by talking about the boundary,
98
270824
4346
我今天的演讲是从谈论“边界”问题开始的，
04:47
but if we remove this boundary,
99
275170
2680
如果我们能除去这一边界，
04:49
the only boundary left is our imagination.
100
277850
3888
剩下的就是我们无边无际的想像力了。
04:53
Thank you.
101
281738
1248
谢谢！
04:54
(Applause)
