Johnny Lee’s Wiimote magic

Via O’Reilly Radar I came across this video by Johnny Lee on DIY Multitouch with the Wiimote.

Johnny Chung Lee is a graduate student at the Human-Computer Interaction Institute at Carnegie Mellon University. He’s a gifted hacker who realized that you can do a lot more with the Nintendo Wii remote than play games with it. The Wii remote is a cheap, well-engineered widget for accurately tracking up to four infrared light sources. That’s the short technical description, but I love the fact that guys like Johnny Lee can take that description and then say “Hey, I can take this and make a cheap electronic white board.”

Watch the video, and then look at the rest of his stuff on YouTube. The Head Tracking for Desktop VR Displays is particularly impressive.
