　　I'm wearing a camera, just a simple web cam, a portable, battery-powered projection 1 system with a little mirror. 我佩戴着一个相机，就是一个简单的网络摄像头，一个便携的用电池供电的投影仪和一个小镜子。

　　These components 2 communicate to my cell phone in my pocket which acts as the communication and computation device. 这些组件跟我口袋中的手机进行通讯，手机作为一个通讯和计算的设备。
　　And in the video here we see my student Pranav Mistry, who's really the genius who's been implementing 3 and designing this whole system. 画面中是我的天才学生Pranav Mistry，他设计并制造了这整套系统。
　　And we see how this system lets him walk up to any surface and start using his hands to interact with the information that is projected in front of him. 我们可以看到，当他靠近任何表面时，信息就会被投影到表面上，他就用双手来进行操作。
　　The system tracks the four significant fingers. 系统会跟踪四个主要的手指。
　　In this case, he's wearing simple marker caps that you may recognize. 在这里，你可以看到他戴着用于标示的指套。
　　But if you want a more stylish 4 version, you could also paint your nails in different colors. 如果你想要更美观，可以把你的指甲染成不同的颜色。
　　And the camera basically tracks these four fingers and recognizes any gestures that he's making so he can just go to, 摄像头会跟踪这四个手指，识别他的任何手势，
　　for example, a map of Long Beach, zoom 5 in and out, etc. 例如，他可以打开Long Beach的地图，进行放大或者缩小等等操作。
　　The system also recognizes iconic gestures such as the "take a picture" gesture, and then takes a picture of whatever is in front of you. 这个系统也能识别“象征性手势”，比如，当你做出这个“拍照手势”，系统就会拍照，把你面前的东西拍下来。
　　And when he then walks back to the Media Lab, he can just go up to any wall and project all the pictures that he's taken, 当他回到Media Lab实验室之后，他可以走近任何一面墙，投影出他拍的所有照片，
　　sort through them and organize them, and re-size them, etc., again using all natural gestures. 用各种自然手势，进行整理、归类、改变大小等各种操作。所有操作都用手势来完成。
