So, as researchers, something that we often do is use immense resources to achieve certain capabilities, or achieve certain goals. 做为一个研究人员,我们经常用极大的资源 来实现一些特定功能、或目标。
immense:adj.巨大的,广大的;无边无际的;非常好的; resources:n.[计][环境]资源; v.向…提供资金(resource的第三人称单数);
And this is essential to the progress of science, or exploration of what is possible. 这对科学进步和可行性探索是必要的。 这对科学进步和可行性探索是必要的。
essential:n.要点;要素;实质;必需品;adj.完全必要的;必不可少的;极其重要的;本质的; exploration:n.探索;勘探;探险;[医]探查术;
But it sort of creates this unfortunate situation where a tiny, tiny fraction of the world can actually participate in this exploration or can benefit from that technology . 但是,这种方式造成了一个不幸的情形, 就是只有世界很小很小的一部分人, 可以参与这个探索, 或从科技中获益。
fraction:n.分数;小部分;小数;少量; participate:v.参加;参与; technology:n.技术;工艺;术语;
And something that motivates me, and what gets me really excited about my research is when I see simple opportunities to drastically change that distribution , and make the technology accessible to a much wider percentage of the population. 一个激发我, 让我对自己的研究充满了热情的原因, 是当我看到了很简单的机会 可以显著改善这种分布不均的局面, 让更多人接近科技。 让更多人接近科技。
motivates:v.促使;刺激;给与动机(motivate的三单形式); drastically:adv.彻底地;激烈地; distribution:n.分布;分配;分发;分销; accessible:adj.易接近的;可进入的;可理解的; percentage:n.百分比;百分率;利润的分成;提成;
And I'm going to show you two videos that have gotten a lot of attention recently that I think embody this philosophy . 我准备播放两段视频, 最近很多人关注它们, 而且它们也体现了我之前的观点。
recently:adv.最近;新近; embody:v.具体表现,体现,代表(思想或品质);包括; philosophy:n.哲学;哲理;人生观;
And they actually use the Nintendo Wii remote . 它们其实用的是任天堂游戏机Wii的遥控器,
Nintendo:n.任天堂(日本电子游戏公司及其开发的电脑游戏名称); remote:adj.偏远的;偏僻的;遥远的;久远的;
Now, for those of you who aren't familiar with this device , it's a 40 dollar video game controller. 如果你不熟悉这个小玩意的话, 它是一个40美元的游戏机控制器。
familiar:adj.熟悉的;常见的;亲近的;n.常客;密友; device:n.装置;策略;图案; video game:n.电子游戏;
And it's mostly advertised for it's motion sensor capabilities, so you can swing a tennis racket , or hit a baseball bat. 它最出名的地方就是它的运动传感器。 你可以像这样挥一个网球拍,或者是棒球棍。

But what actually interests me a lot more is the fact that in the tip of each controller is a relatively high-performing infrared camera. 但其实更让我感兴趣的, 是这个遥控器顶部的 一个比较高性能的红外照相机。
tip:n.小窍门,小费;v.给…小费;使倾斜; relatively:adv.相当程度上;相当地;相对地; infrared:n.红外线;adj.红外线的;
And I'm going to show you two demos of why this is useful. 我这就做两个演示来告诉你为什么它很有用。
demos:n.民众;人民;游行;录音样带(demo的复数形式);
So here I have my computer setup with the projector , and I have a Wii remote sitting on top of it. 这是我的电脑,连着投影仪, 我把一个Wii遥控器放在上面。
projector:n.[仪]投影仪;放映机;探照灯;设计者;
And for example, if you're in a school that doesn't have a lot money, which is probably a lot of schools, or if you're in an office environment, and you want an interactive whiteboard , normally these cost about two to three thousand dollars. 比如说,一所学校, 没有很多钱,大概大部分的学校都是这样, 或者是办公室, 如果你想有一个交互式电子白板, 一般要花上2000到3000美元。
interactive:adj.合作的;相互影响的;互相配合的;交互式的;n.交互式视频设备; whiteboard:n.白色书写板; normally:adv.正常地;通常地,一般地;
So what I'm going to show you how to do is how to create one with a Wii remote. 而现在我就要演示, 怎么用一个Wii的遥控器来做一个电子白板。
Now, this requires another piece of hardware , which is this infrared pen. 这还需要另外一个硬件, 一个发射红外线的笔。
hardware:n.计算机硬件;五金器具;
You can probably make this yourself for about five dollars with a quick trip to the Radio Shack . 你自己做一个只需要5块钱, 元件可以在Radio Shack（美国电器公司）买到。
Shack:n.棚屋;小室;vi.居住;
It's essentially got a battery , a button and an infrared LED, and it turns on -- you guys can't see it -- but it turns on whenever I push the button. 它是由一节电池,一个开关和一个红外发光二极管组成的。 按开关可以让它发射红外线,当然肉眼是看不见的, 但是我一按开关它就会发射。
essentially:adv.本质上;本来; battery:n.[电]电池,蓄电池;n.[法]殴打;n.[军]炮台,炮位;
Now, what this means is that if I run this piece of software, the camera sees the infrared dot, and I can register the location of the camera pixels to the projector pixels. And now this is like a whiteboard surface. 这就意味,如果我运行这个软件, 红外照相机就可以看见这个红外线的点, 软件把红外摄像机的像素位置对应到投影仪的像素位置。 现在它就变成了一个电子白板。
register:v.登记;注册;记录;n.登记簿;登记表;注册簿; location:n.地方;地点;位置;定位 pixels:n.像素(组成屏幕图像的最小独立元素);(pixel的复数)
(Applause) （掌声）
So for about 50 dollars of hardware, you can have your own whiteboard. 所以只用50美元的硬件,你就可以做自己的电子白板了。
This is Adobe Photoshop. 这是 Adobe Photoshop（著名图形软件）。
Adobe:n.(建筑用)黏土;黏土坯;adj.用砖坯砌的;
(Applause) （掌声）
Thank you. 谢谢。
(Laughter) （笑声）
Now, the software for this I've actually put on my website and have let people download it for free. 我把这个软件放在了我的网站上, 大家都可以免费下载。
And in the three months that this project has been public it's been downloaded over half a million times. 在这个设计面世3个月里, 已经有50万人下载了。
So teachers and students all around the world are already using this. 全世界的老师和学生们 都已经用到了它。
(Applause) （掌声）
I want to quickly say that although it does do it for 50 dollars, there are some limitations of this approach . 我想说明一下,虽然50美元的硬件能满足大部分要求, 这个方案还是有它的局限和不足。
limitations:n.局限性;(限制)因素;边界(limitation的复数形式); approach:n.方法;路径;v.接近;建议;着手处理;
But you get about 80 percent of the way there, for about one percent of the cost. 但是你实现80%的功能, 只用了1%的花销。
Another nice thing is that a camera can see multiple dots, so this is actually a multi-touch , interactive whiteboard system as well. 另外一个优点就是红外摄像机可以探测到多个点。 所以, 这其实是一个多点触控的电子白板。
multiple:adj.数量多的;多种多样的;n.倍数; multi-touch:多点触摸;
(Applause) （掌声）
For the second demo, I have this Wii remote that's actually next to the TV. 第二个演示,我把这个Wii遥控器 放在电视旁边。

display:n.显示;炫耀;vt.显示;表现;陈列;vi.[动]作炫耀行为;adj.展览的;陈列用的;
And why this is interesting is that if you put on, say, a pair of safety glasses, that have two infrared dots in them, what these two dots are essentially going to give you is give the computer an approximation of your head location. 它有趣的地方是 如果你带上一副保险眼镜, 眼镜上有两个红外发光点, 这两个红外发光点 可以让电脑知道你头部的大概位置。
approximation:n.[数]近似法;接近;[数]近似值;

application:n.应用;申请;应用程序;敷用;
And you can see that it looks like a 3D room if you can see, kind of like a video game, it sort of looks 3D, but for the most part , the image looks pretty flat, and bound to the surface of the screen. 你可以把它看成三维房间, 就像在游戏里的三维一样。 但是,这个画面看起来还是平面的, 它被屏幕的表面所局限。
for the most part:adv.在极大程度上,多半; bound:n.跳跃:v.跳跃着跑:形成…的边界(或界限)adj.一定会:很可能会:

Because this is about 10 dollars of additional hardware if you already have a Nintendo Wii. 因为这只需要额外10美金左右的硬件, 如果你已经有了任天堂Wii游戏机的话。
additional:adj.附加的,额外的;
So I'm looking forward to seeing some games, and actually Louis Castle, that's him down there, last week announced that Electronic Arts, one of the largest game publishers , is releasing a game in May that has a little Easter egg feature for supporting this type of head tracking. 我很期待一些游戏的推出, 其实Louis Castle,他就在下面, 上星期宣告了Electronic Arts,（美国著名游戏公司） 世界上最大的游戏发行商之一,在5月要推出一款游戏, 里面有一个小惊喜的彩蛋功能 支持了这种头部的追踪。

But actually, to me, what's almost more interesting than either of these two products, is how people actually found out about them. 但是其实,对于我来说,更有趣的 比这两个产品更有趣的, 是人们怎么发现了他们。
YouTube has really changed the way, or changed the speed, in which a single individual can actually spread an idea around the world. YouTube（美国视频网站） 改变了 一个个体 可以向这个世界传播想法的方式和速度。
individual:n.个人;有个性的人;adj.单独的;个别的;
You know, I'm doing some research in my lab with a video camera , and within the first week, a million people had seen this work, and literally within days, engineers, teachers and students 你知道,我不过是用摄像头记录了自己实验室里的一些研究, 一个星期之内,有百万人看到了我的工作, 在几天之内,来自各个地方的工程师,老师,学生

from around the world, were already posting their own YouTube videos of them using my system or derivatives of this work. 都在YouTube上传了视频 演示他们使用我的系统,或者是这个系统的延伸。
