　　Johnny Lee

　　Researcher Johnny Lee became a YouTube star with his demo of Wii Remote hacks — bending the low-cost game piece to power an interactive whiteboard, a multitouch surface, a head-mounted display ...

　　Why you should listen

　　To understand Johnny Lee, just take a look at his website. Aside from his Wii Remote hacks -- voted the #1 tech demo of all time by Digg -- you can see all the other places his mind has turned: typography, photography, urban renewal ... to say nothing of his interesting sideline in Little Great Ideas, like the hypnotic "___ will ___ you."

　　After earning his PhD from the Human-Computer Interaction Institute at Carnegie Mellon University, he joined the team at Microsoft responsible for Project Natal, a controller-free motion sensing device for the Xbox 360. He's since turned his attention to accelerated technology R&D at Google.

　　What others say

　　“This guy deserves a medal.” — Cmdr Taco, Slashdot

　　So, as researchers, something that we often do is use immense resources to achieve certain capabilities, or achieve certain goals. And this is essential to the progress of science, or exploration of what is possible. But it creates this unfortunate situation where a tiny, tiny fraction of the worldcan actually participate in this exploration or can benefit from that technology. Something that motivates me, and 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.

　　I'm going to show you two videos that have gotten a lot of attention that I think embody this philosophy. And they actually use the Nintendo Wii Remote. For those of you who aren't familiar with this device, it's a $40 video game controller. And it's mostly advertised for its motion-sensing capabilities: so you can swing a tennis racket, or hit a baseball bat. 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.And I'm going to show you two demos of why this is useful.

　　So here, I have my computer set up with the projector, and I have a Wii Remote sitting on top of it.And, for example, if you're in a school that doesn't have a lot money, 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. So I'm going to show you how to create one with a Wii Remote. Now, this requires another piece of hardware, which is this infrared pen. You can probably make this yourself for about five dollars with a quick trip to the Radio Shack. It's got a battery, a button and an infrared LED -- you guys can't see it -- but it turns on whenever I push the button.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 an interactive whiteboard surface.
