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我們已經 been striving努力 to shorten縮短 the gap間隙 between之間 us
1
3581
3247
我們不斷地嘗試縮短
00:18
and digital數字 information信息,
2
6828
1594
我們與數位資訊之間的距離
00:20
the gap間隙 between之間 our physical物理 world世界
3
8422
1834
也就是實體世界
00:22
and the world世界 in the screen屏幕
4
10256
1798
與螢幕中虛擬世界的距離
00:24
where our imagination想像力 can go wild野生.
5
12054
2842
在虛擬世界裡
我們總是可以盡情發揮想像力
00:26
And this gap間隙 has become成為 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
00:33
and now this gap間隙 is shortened縮短 down
8
21588
1486
現在這個距離已經縮短到
00:35
to less than a millimeter毫米,
9
23074
1468
不到一毫米了
00:36
the thickness厚度 of a touch-screen觸摸屏 glass玻璃,
10
24542
1878
也就是觸控式螢幕厚度的距離
00:38
and the power功率 of computing計算
11
26420
1450
任何人
00:39
has become成為 accessible無障礙 to everyone大家.
12
27870
4903
都可以使用電腦
00:44
But I wondered想知道, what if there could be no boundary邊界 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
00:49
I started開始 to imagine想像 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創建 this tool工具
15
41556
2451
首先 我做出了這個工具
00:56
which哪一個 penetrates滲透 into the digital數字 space空間,
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屏幕,
17
46516
2091
所以當你用力地壓螢幕時
01:00
it transfers轉讓 its physical物理 body身體 into pixels像素.
18
48607
3333
這個工具可以把你的身體
轉換成為螢幕上的像素
01:03
Designers設計師 can materialize物質化 their ideas思路
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外科醫生 can practice實踐 on virtual虛擬 organs器官
21
55748
2552
外科醫生也可以在
01:10
underneath the screen屏幕.
22
58300
2224
螢幕中的虛擬器官上做練習
01:12
So with this tool工具, this boundary邊界 has been broken破碎.
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
01:17
But our two hands still remain outside the screen屏幕.
24
65421
2967
即使如此
我們的手還是停留在螢幕外
01:20
How can you reach達到 inside and interact相互作用
25
68388
2484
有沒有可能直接把手伸進電腦
01:22
with the digital數字 information信息
26
70872
1427
透過我們靈巧的雙手
01:24
using運用 the full充分 dexterity靈巧 of our hands?
27
72299
3004
直接使用這些數位資訊呢?
01:27
At Microsoft微軟 Applied應用的 Sciences科學,
28
75303
2302
我在微軟的應用科學部門裡
01:29
along沿 with my mentor導師 Cati卡齊 Boulanger布朗熱,
29
77605
1916
和著我的指導教授 Cati Boulanger
01:31
I redesigned重新設計 the computer電腦
30
79521
1271
重新設計出這台電腦
01:32
and turned轉身 a little space空間 above以上 the keyboard鍵盤
31
80792
2881
把鍵盤上面這個小小的空間
01:35
into a digital數字 workspace工作區.
32
83673
2365
轉變成為一個數位化工作區
01:38
By combining結合 a transparent透明 display顯示 and depth深度 cameras相機
33
86038
2311
是透過一個透明顯示器
跟3D距離相機的組合
01:40
for sensing傳感 your fingers手指 and face面對,
34
88349
1840
去感應你的手指跟臉
01:42
now you can lift電梯 up your hands from the keyboard鍵盤
35
90189
2234
於是你就可以將你的手
從鍵盤上抬起來
01:44
and reach達到 inside this 3D space空間
36
92423
2914
並且就此進入3D的空間
01:47
and grab pixels像素 with your bare hands.
37
95337
2500
並且可以直接用你的手
來抓住像素
01:49
(Applause掌聲)
38
97837
2971
(鼓掌聲)
01:52
Because windows視窗 and files have a position位置 in the real真實 space空間,
39
100808
4206
因為視窗跟檔案
都在真實地存在這個空間裡
01:57
selecting選擇 them is as easy簡單 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
02:00
Then you can flip翻動 through通過 this book
41
108373
2153
你也可以這樣翻閱這本書
02:02
while highlighting突出 the lines, words
42
110526
1717
當要在某句話
或某些字上畫重點的時候
02:04
on the virtual虛擬 touch觸摸 pad below下面 each floating漂浮的 window窗口.
43
112243
2564
就螢幕下方的觸控板上劃過去即可
02:06
Architects建築師 can stretch伸展 or rotate迴轉 the models楷模
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例子,
46
119767
1620
所以在這些例子裡面
02:13
we are reaching到達 into the digital數字 world世界.
47
121387
2737
我們是真的進入了數位的世界
02:16
But how about reversing倒車 its role角色
48
124124
2346
還有沒有可能是相反過來
02:18
and having the digital數字 information信息 reach達到 us instead代替?
49
126470
4819
讓數位資訊直接跑到我們面前呢
02:23
I'm sure many許多 of us have had the experience經驗
50
131289
1756
我相信我們當中許多人
02:25
of buying購買 and returning回國 items項目 online線上.
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擔心 about it.
52
135468
1793
現在你不需要再擔心了
02:29
What I got here is an online線上 augmented增強 fitting配件 room房間.
53
137261
4822
你所看到的是一個網路實境試衣間
02:34
This is a view視圖 that you get from
54
142083
1902
當系統辨識出你的身型之後
02:35
head-mounted頭戴式 or see-through透視 display顯示
55
143985
1744
這個影像就會
02:37
when the system系統 understands理解 the geometry幾何 of your body身體.
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理念 further進一步, I started開始 to think,
57
150876
3551
延伸這個想法,我開始想
02:46
instead代替 of just seeing眼看 these pixels像素 in our space空間,
58
154427
3369
有沒有可能不光是
在三度空間裡用肉眼看到像素
02:49
how can we make it physical物理
59
157796
1522
而是讓像素具體化
02:51
so that we can touch觸摸 and feel it?
60
159318
4262
讓我們可以摸得到
跟感覺得到它呢
02:55
What would such這樣 a future未來 look like?
61
163580
3049
這樣的未來會是什麼樣子?
02:58
At MITMIT Media媒體 Lab實驗室, along沿 with my advisor顧問 Hiroshi Ishii石井
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
03:02
and my collaborator合作者 RehmiRehmi Post崗位,
63
170287
2023
以及我的合作夥伴 Rehmi Post
03:04
we created創建 this one physical物理 pixel像素.
64
172310
3644
一起研發出這一個具像化的畫素
03:07
Well, in this case案件, this spherical球形 magnet磁鐵
65
175954
2624
這組模組中的球狀磁鐵
03:10
acts行為 like a 3D pixel像素 in our space空間,
66
178578
2352
就好像是現實生活中的3D像素
03:12
which哪一個 means手段 that both computers電腦 and people
67
180930
2904
也就是說無論是
使用電腦或人用手
03:15
can move移動 this object目的 to anywhere隨地
68
183834
1898
都可以在這個小小的三度空間裡
03:17
within this little 3D space空間.
69
185732
1969
自由且同步地移動它
03:19
What we did was essentially實質上 canceling取消 gravity重力
70
187701
3492
基本上我們所做的
就是拿掉重力這個因素
03:23
and controlling控制 the movement運動 by combining結合
71
191193
2139
透過結合磁浮
03:25
magnetic磁性 levitation磁懸浮 and mechanical機械 actuation啟動
72
193332
2824
及力學效應
03:28
and sensing傳感 technologies技術.
73
196156
2477
再加上感應技術
來讓它動起來
03:30
And by digitally數字 programming程序設計 the object目的,
74
198633
2505
並透過程式來將物件數位化
03:33
we are liberating解放 the object目的 from constraints限制
75
201138
2777
就讓它脫離了時間空間的限制
03:35
of time and space空間, which哪一個 means手段 that now,
76
203915
3435
也就是說現在
03:39
human人的 motions運動 can be recorded記錄 and played發揮 back
77
207350
3896
人的動作可以被紀錄並重新播放
03:43
and left permanently永久 in the physical物理 world世界.
78
211246
3619
並且在現實生活中被永久保存下來
03:46
So choreography編舞 can be taught physically物理 over distance距離
79
214865
3033
所以現在芭蕾舞
也可以進行遠距教學
03:49
and Michael邁克爾 Jordan's約旦 famous著名 shooting射擊 can be replicated複製
80
217898
2525
麥可喬丹的傳奇飛人之姿
03:52
over and over as a physical物理 reality現實.
81
220423
3549
也可以真實地一再重現
03:55
Students學生們 can use this as a tool工具
82
223972
2180
學生也可以使用它
03:58
to learn學習 about the complex複雜 concepts概念
83
226152
1942
來學習像行星運動或物理學
04:00
such這樣 as planetary行星 motion運動, physics物理,
84
228094
4084
這類比較複雜的概念
04:04
and unlike不像 computer電腦 screens屏幕 or textbooks教科書,
85
232178
2819
相較於一般的電腦螢幕或教科書
04:06
this is a real真實, tangible有形 experience經驗
86
234997
2482
這是個有形有體的真實經驗
04:09
that you can touch觸摸 and feel, and it's very powerful強大.
87
237479
3658
你可以觸摸跟實際感受
這會令人印象深刻
04:13
And what's more exciting扣人心弦
88
241137
1982
更令人興奮的是
04:15
than just turning車削 what's currently目前 in the computer電腦 physical物理
89
243119
3348
不是只是將電腦裡的東西實體化
04:18
is to start開始 imagining想像 how programming程序設計 the world世界
90
246467
3189
而是當我們生活週遭
很多東西開始被程式化之後
04:21
will alter改變 even our daily日常 physical物理 activities活動.
91
249656
3696
我們的日常生活也將會隨之改變
04:27
(Laughter笑聲)
92
255460
2483
(笑聲)
04:29
As you can see, the digital數字 information信息
93
257943
2756
就如各位所看到的
04:32
will not just show顯示 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開始 directly acting演戲 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部分 of our physical物理 surroundings環境
96
264327
2299
就好像是我們生活週遭的一部份
04:38
without disconnecting斷開 ourselves我們自己 from our world世界.
97
266626
4198
我們不再需要將自己
從這個世界中抽離出來
04:42
Today今天, we started開始 by talking about the boundary邊界,
98
270824
4346
我們今天是從這層隔閡開始講起
04:47
but if we remove去掉 this boundary邊界,
99
275170
2680
但如果這層隔閡不再復存
04:49
the only boundary邊界 left is our imagination想像力.
100
277850
3888
那唯一會限制我們的
就只剩下自己的想像力了
04:53
Thank you.
101
281738
1248
謝謝
04:54
