Multi-touch Interface using the Wii Remote

This is another incredibly cool Wiimote hack from Johnny Chung Lee (see previous post) that suggests all kinds of interesting possibilities for controlling digital puppet characters in real-time. Since the Wii tracks IR lights, Johnny has discovered that almost any surface - a projector screen, a tabletop, or an LCD - can be turned into a multi-touch screen that you can use like the iPod touch or iPhone. All you need is the Wiimote, a ball point pen equipped with an LED and some free software that can be downloaded here. Watch the video for details.

And as cool as it is, I'm even more excited to see the results of what Johnny is working on next - 3D tracking and head tracking with the Wiimote!

Special thanks to Brian for sending this to me!
