身為研究人員，我們常會運用大量的資源

So, as researchers, something that we often do is use immense resources

to achieve certain capabilities, or achieve certain goals.

來完成特定功能，或達成特定目標。

這是科學進步

And this is essential to the progress of science,

和探索可能性的要素。

or exploration of what is possible.

但有點可惜的是

But it creates this unfortunate situation

世界上有些地方，

where a tiny, tiny fraction of the world

無法參與這些探索

can actually participate in this exploration

或是無法從這些科技中受益。

or can benefit from that technology.

因而激勵我進行研究，

Something that motivates me,

並且讓我感到振奮的是，

and gets me really excited about my research,

我發現可以透過一些簡單的方法，

is when I see simple opportunities

改變傳播的過程，

to drastically change that distribution and make the technology accessible

讓更多人

從這些科技中受益。

to a much wider percentage of the population.

我想給大家看二支

I'm going to show you two videos that have gotten a lot of attention

最近受到囑目的影片，

它們具體展現了這個想法。

that I think embody this philosophy.

我用的是任天堂 Wii 遙桿

And they actually use the Nintendo Wii Remote.

對於知道它的人來說，

For those of you who aren't familiar with this device,

它不過是市價 40 美元的電玩控制器。

it's a $40 video game controller.

它是用來做動作感應，

And it's mostly advertised for its motion-sensing capabilities:

能用它做出揮動網球拍，或打擊棒球的動作。

so you can swing a tennis racket, or hit a baseball bat.

但事實上，真正吸引我的是，

But what actually interests me a lot more

它前端這個

is the fact that in the tip of each controller

高性能紅外線鏡頭。

is a relatively high-performing infrared camera.

我將要給你看兩個示範，說明它為什麼很有用。

And I'm going to show you two demos of why this is useful.

這邊架設了電腦和投影機，

So here, I have my computer set up with the projector,

Wii 遙控器則放在上面。

and I have a Wii Remote sitting on top of it.

假設你的學校

And, for example, if you're in a school that doesn't have a lot money,

沒有錢，就如同大部份學校一樣，

probably a lot of schools,

或是你在一個辦公室裡

or if you're in an office environment, and you want an interactive whiteboard,

需要一個互動式電子白板，

它的市價大概要 2 至 4 千美元。

normally these cost about two to three thousand dollars.

我來告訴你們如何

So I'm going to show you how to create one with a Wii Remote.

用 Wii 遙控器製做一個電子白板。

你需要另外做一支紅外線筆

Now, this requires another piece of hardware,

做一支紅外線筆。

which is this infrared pen.

只要到 RadioShack（美國電子產品零售商）

You can probably make this yourself for about five dollars

花 5 美元購買以下零件。

with a quick trip to the Radio Shack.

1 顆電池、1 個按鈕、1 個紅外線 LED（發光二極體），

It's got a battery, a button and an infrared LED --

按下按鈕，紅外線 LED 就會發光，

you guys can't see it --

當然，肉眼是看不見紅外線的。

but it turns on whenever I push the button.

現在讓我執行這個軟體，

Now, what this means is that if I run this piece of software,

就能讓鏡頭能看見紅外線光點，

the camera sees the infrared dot,

接下來把它們的位置由鏡頭像素，

and I can register the location of the camera pixels

對應到投影機像素。現在它成了互動式電子白板啦！

to the projector pixels.

And now this is like an interactive whiteboard surface.

（掌聲）

(Applause)

只要 50 美元，你就能擁有自己的電子白板。

So for about $50 of hardware, you can have your own whiteboard.

這個是 Adobe Photoshop。

This is Adobe Photoshop.

（掌聲）

(Applause)

Thank you.

謝謝。

（笑聲）

(Laughter)

這個程式放在我的網站

The software for this I've actually put on my website

免費下載。

and have let people download it for free.

自公開以來，

In the three months this project has been public,

它在 3 個月內已被下載數十萬次。

it's been downloaded over half a million times.

現在世界各地的老師學生

So teachers and students all around the world

已經開始使用它。

are already using this.

（掌聲）

(Applause)

我要聲明一下，它雖然只要 50 美元，

Although it does do it for 50 dollars,

而且，這個做法仍有些限制。

there are some limitations of this approach.

不過想想，以 1% 的成本

You get about 80 percent of the way there, for one percent of the cost.

就能達到 80% 的效果。

另一個好消息是，這個鏡頭可以同時辨識多個光點，

Another nice thing is that a camera can see multiple dots,

所以它還是個

so this is actually a multi-touch, interactive whiteboard system as well.

多點觸控電子白板。

（掌聲）

(Applause)

在第二個展示中，我將 Wii 遙控器

For the second demo,

I have this Wii Remote that's actually next to the TV.

放在電視旁邊。

這次它不再指向螢幕

So it's pointing away from the display, rather than pointing at the display.

而是指向看電視的人。

有趣的是，

And why this is interesting

如果我在這副眼鏡上頭

is that if you put on, say, a pair of safety glasses,

放入 2 個紅外線光點

that have two infrared dots in them,

它就能告訴電腦

they are going to give the computer an approximation of your head location.

你的頭部位置。

更有趣的是，

And why this is interesting

這個電腦螢幕正執行著一個程式，

is I have this sort of application running on the computer monitor,

顯示一些標靶漂浮在 3D 房間裡。

which has a 3D room, with some targets floating in it.

就像很多遊戲裡看到的一樣，

And you can see that it looks like a 3D room.

kind of like a video game, it sort of looks 3D,

它看起來像是 3D，

不過這些影像不但看起來很平，

but for the most part, the image looks pretty flat,

也釘在畫面上不能動。

and bound to the surface of the screen.

現在如果我們把頭部追蹤打開，

But if we turn on head tracking --

電腦就能改變螢幕上的影像，

the computer can change the image that's on the screen

讓它們與你的頭部互動。

and make it respond to the head movements.

我們回頭看看。

So let's switch back to that.

（笑聲）

(Laughter)

(Applause)

（掌聲）

So this has actually been a little bit startling

這著實令遊戲開發業者

吃驚。

to the game-development community.

（笑聲）

(Laughter)

因為只要你擁有任天堂 Wii，

Because this is about 10 dollars of additional hardware

再加上 10 美元的額外硬體費用就行了。

if you already have a Nintendo Wii.

我希望遊戲採用它

So I'm looking forward to seeing some games,

上週 Lou Castle（EA 副總裁），也就是台下坐的這位，

and actually Louis Castle, that's him down there,

宣佈 EA（美商藝電），

last week announced that Electronic Arts, one of the largest game publishers,

最大的遊戲發行商之一，將在 5 月發表一款遊戲

is releasing a game in May that has a little Easter egg feature

附有支援頭部

追蹤的隱藏功能。

for supporting this type of head tracking.

在不到 5 個月的時間內，

And that's from less than five months

將我的實驗原型變成為商業產品

from a prototype in my lab to a major commercial product.

（掌聲）

(Applause)

Thank you.

謝謝。

(Applause)

事實上，對我而言最有意思的，

But actually, to me, what's almost more interesting

不是這兩個實驗本身，

than either of these two projects

而是人們是如何發現這兩個實驗的。

is how people actually found out about them.

Youtube 改變了

YouTube has really changed the way, or changed the speed,

將個人想法

in which a single individual

散播到全世界的速度或方式。

can actually spread an idea around the world.

我不過是使用攝影機，將我在實驗室內的研究錄下，

I'm doing some research in my lab with a video camera,

在一週之內，就有一百萬人看到，

and within the first week, a million people had seen this work,

and literally within days, engineers, teachers and students

在短短幾天內，就有世界各地的工程師、老師、學生們，

使用我的系統或加以變化，

from around the world were already posting their own YouTube videos

of them using my system or derivatives of this work.

並在 Youtube 發佈他們的影片。

我希望未來能看到更多，

So I hope to see more of that in the future,

也希望線上遊戲的發行，

and hope online video distribution to be embraced by the research community.

可以和研究社群結合。

謝謝大家

So thank you very much.

（掌聲）

(Applause)
