未来科技探索者之X进化

Wii remote hacks | Johnny Lee

作为研究人员 我们经常用极多的资源
So, as researchers, something we often do is use immense resources
去开发一些特定功能或目标
to achieve certain capabilities, or achieve certain goals.
这对科学发展和未知可能性的探索
And this is essential to the progress of science
是相当重要的
or exploration of what is possible.
但是它又造成了一种令人遗憾的境况
But it has already creates an unfortunate situation
就只有世界上一小部分的人
where a tiny, tiny fraction of the world
可以投入到这个探索之中
can actually participate in this exploration
或从该技术中受益
or can benefit from that technology.
一个激励着我
And something that motivates me
并让我为自己研究感到兴奋的原因
and gets me really excited about my research,
是当我看到一些很小的机会
is when I see simple opportunities
可以彻底改善这种分配 还能使得这技术
to drastically change that distribution and make the technology accessible
为更广泛地为更多人群所用
to a much wider percentage of the population.
我将播放两个最近颇受关注的视频
I’m going to show you two videos that have gotten a lot of attention recently
可以体现我之前的观点
that I think embody this philosophy.
它们运用的是任天堂的Wii遥控器
And they actually use the Nintendo Wii Remote.
现在呢 鉴于现场有些观众还不是很了解这个设备
Now,for those of you who aren’t familiar with this device,
这是一个40美元的电视游戏控制器
it’s a $40 video game controller.
广告上说的最多的就是它的体感性能
And it’s mostly advertised for its motion-sensing capabilities:
让你好似在挥舞着一个网球拍或棒球棍
so you can swing a tennis racket, or hit a baseball bat.
但真正吸引我的是
But what actually interests me a lot more
是每个控制器的顶端
is the fact that in the tip of each controller
都有一个高质量的红外线摄像头
is a relatively high-performing infrared camera.
我会做两个演示来说明它的实用性
And I’m going to show you two demos of why this is useful.
现在我将电脑和投影仪连接起来
So here, I have my computer set up with the projector,
并且我还放了个wii遥控在这上面
and I have a Wii Remote sitting on top of it.
假设你在学校里 且学校钱不多
And, for example, if you’re in a school that doesn’t have a lot money,
很多学校都那样吧
probably a lot of schools,
或者说你在办公室 想要一个交互式的白板
or if you’re in an office environment, and you want an interactive whiteboard,
它们正常价格在两千到三千美元
normally these cost about two to three thousand dollars.
接下来让我演示下如何用wii遥控来 创造一个交互式白板
So I’m going to show you how to create one with a Wii Remote.
首先 它需要另一个硬件
Now, this requires another piece of hardware,
就是这个红外线感应笔
which is this infrared pen.
你也可以自己动手制作一个 大概花费5美元
You can probably make this yourself for about five dollars
元件可以在Radio Shack电器零售公司买到
with a quick trip to the Radio Shack.
它包含一块蓄电池、一个按钮以及一个红外线LED灯
It’s got a battery, a button and an infrared LED —
你们肉眼是看不见的
and turns on you guys can’t see it —
我只要按下开关它就会发射
but it turns on whenever I push the button.
嗯 意思就是 如果我运行这个软件
Now, what this means is that if I run this piece of software,
我现在可以记录通过摄像头观察到的红外线点
I can now register the camera sees the infrared dot,
我也可以记录摄像机像素点到
and I can register the location of the camera pixels
投影仪的像素点
to the projector pixels.
现在 这已然是一个交互式的写字白板
And now this is an interactive whiteboard surface.
(鼓掌)
(Applause)
所以只需要50美元你就可以拥有一块自己的手写板
So for about $50 of hardware, you can have your own whiteboard.
这是款图像处理软件
This is Adobe Photoshop.
(鼓掌)
(Applause)
谢谢你们!
Thank you.
(大笑)
(Laughter)
实际上这款软件我已经放到了我的网站上
Now the software for this I’ve actually put on my website
人们可以免费的下载它
and have let people download it for free.
在三个月内 这款软件已经成功上市了
In the three months this project has been public,
它已经被下载超过了50万次
it’s been downloaded over half a million times.
现在全世界的老师和学生们
So teachers and students all around the world
都已经在用它了
are already using this.
(鼓掌)
(Applause)
我想说 尽管50美元能满足大部分需求
I want quickly say that although it does do it for 50 dollars,
这个方法还是有它的一些局限
there are some limitations of this approach.
但你已经用十分之一的钱换来了80%的体验
You get about 80 percent of the way there, for one percent of the cost.
另一个优点是红外摄像头可以探测到多个点
Another nice thing is that a camera can see multiple dots,
所以实际上这是一个多点触控的交互式白板系统
so this is actually a multi-touch, interactive whiteboard system as well.
(鼓掌)
(Applause)
第二个演示中
For the second demo,
我把wii遥控放在了电视旁边
I have this Wii Remote that’s actually next to the TV.
所以现在它并不是直接指向投影仪
So it’s pointing away from the display, rather than pointing at the display.
它有趣的地方是 在这儿
And why this is interesting
如果你戴上一副感应眼镜
is that if you put on, see, a pair of safety glasses,
眼镜上有两个红外发光点
that have two infrared dots in them,
这两个红外点 会把你头部的大概位置发送给电脑
What these two dots are going to give you is give the computer an approximation of your head location.
有趣的是
And why this is interesting
电脑监控器上正在运行的程序
is I have this sort of application running on the computer monitor,
那是个有目标点浮动的三维平面
which has a 3D room, with some targets floating in it.
你能看出它确实像一个三维房间
And you can see that it looks like a 3D room.
就像是某种全息游戏
kind of like a video game, it sort of looks 3D,
但这些图像大都是都是非常平面的
but for the most part, the image looks pretty flat,
被束缚在屏幕的表面
and bound to the surface of the screen.
如果我们把头部跟踪器打开
But if we turn on head tracking —
电脑就可以改变屏幕上的图案
the computer can change the image that’s on the screen
让它随着头部运动而改变
and make it respond to the head movements.
来 让我们调回去再看看
So let’s switch back to that.
(大笑)
(Laughter)
鼓掌
(Applause)
鼓掌
(Applause)
所以对游戏开发界而言
So this has actually been a little bit startling
这个的确令人惊讶
to the game-development community.
(大笑)
(Laughter)
因为这仅需要大约10美元的额外硬件
Because this is about 10 dollars of additional hardware
前提是你已经拥有了一个任天堂wii主机
if you already have a Nintendo Wii.
所以我期待能看到一些游戏
So I’m looking forward to seeing some games,
而且Louis Castle… 他就在那里
and actually Louis Castle, that’s him down there,
他宣布世界上最大的游戏发行商之一EA
last week announced that Electronic Arts, one of the largest game publishers,
将在5月推出一款有一些彩蛋的游戏
is releasing a game in May that has a little Easter egg feature
就是为了支持这个头部追踪装置
for supporting this type of head tracking.
并且在不到5个月内
And that’s from less than five months
从我开发的原型制作 变成一个商业成品
from a prototype in my lab to a major commercial product.
(鼓掌)
(Applause)
谢谢
Thank you.
(鼓掌)
(Applause)
但实际上 比起这两个项目
But actually, to me, what’s almost more interesting
真正吸引我的是
than either of these two projects
是人们如何发现它们的
is how people actually found out about them.
YouTube视频网站确实改变了
YouTube has really changed the way, or changed the speed,
一个个人
in which a single individual
向这个世界传播想法的方式和速度
can actually spread an idea around the world.
我只是用摄像头记录实验室里的一些研究
I’m doing some research in my lab with a video camera,
在第一个星期内就有百万人发现了这个项目
and within the first week, a million people had seen this work,
几天内全世界的工程师、 老师和学生都上传了视频
and literally within days, engineers, teachers and students
演示他们使用我的软件系统
from around the world were already posting their own YouTube videos
或者是这个软件系统的延伸
of them using my system or derivatives of this work.
我希望在未来看到更多的这种事情
So I hope to see more of that in the future,
并希望网上发布视频这种方式可以被研究机构接受
and hope online video distribution to be embraced by the research community.
非常感谢大家!
So thank you very much.
(鼓掌)
(Applause)
