　　So for about $50 of hardware, you can have your own whiteboard. This is Adobe Photoshop.

　　2:16

　　(Applause)

　　2:22

　　Thank you.

　　2:23

　　(Laughter)

　　2:25

　　The software for this I've actually put on my website and have let people download it for free. In the three months this project has been public, it's been downloaded over half a million times. So teachers and students all around the world are already using this.

　　2:38

　　(Applause)

　　2:43

　　Although it does do it for 50 dollars, there are some limitations of this approach. You get about 80 percent of the way there, for one percent of the cost. Another nice thing is that a camera can see multiple dots, so this is actually a multi-touch, interactive whiteboard system as well.

　　For the second demo, I have this Wii Remote that's actually next to the TV. So it's pointing away from the display, rather than pointing at the display. And why this is interesting is that if you put on, say, a pair of safety glasses, that have two infrared dots in them, they are going to give the computer an approximation of your head location. And why this is interesting is I have this sort of application running on the computer monitor, which has a 3D room, with some targets floating in it.And you can see that it looks like a 3D room. 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. But if we turn on head tracking -- the computer can change the image that's on the screen and make it respond to the head movements. So let's switch back to that.

　　3:49

　　(Laughter)

　　3:53

　　(Applause)

　　4:03

　　So this has actually been a little bit startling to the game-development community.

　　4:08

　　(Laughter)

　　4:10

　　Because this is about 10 dollars of additional hardware if you already have a Nintendo Wii. 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. And that's from less than five months from a prototype in my lab to a major commercial product.

　　4:34

　　(Applause)

　　4:39

　　Thank you.

　　4:40

　　(Applause)

　　4:43

　　But actually, to me, what's almost more interesting than either of these two projects is how people actually found out about them. YouTube has really changed the way, or changed the speed, in which a single individual can actually spread an idea around the world. 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 from around the world were already posting their own YouTube videos of them using my system or derivatives of this work. So I hope to see more of that in the future, and hope online video distribution to be embraced by the research community.

　　5:19

　　So thank you very much.

　　5:20

　　(Applause)
