Multi Touch … with a Wii Remote.

I guess that Wii Remote hacks are a bit old hat now, but Johnny Chung Lee has come up with a few nice demonstrations which impressed me a fair bit.

It turns out that (for those like me who didn’t know..) the Wii Remote not only has a 3D axis accelerometer, it also has an infra red camera, which I’d assumed was just a simple infra red emitter. The IR camera is a 1024×768 (1MPixel) with a scan rate of 100hz, which allows you to do some fairly cool things.

In my favourite project Johnny has setup an IR emitter in front of the Wii Remote so that reflective objects will be seen more clearly by the IR Camera in the Wii Remote. Add a couple of finger reflectors to your left and right index fingers and hey-presto you have a functional multi-touch interface for around $50 (£25).
