Woot! I managed to get my Wiimote and infrared pen hack working this evening, so I’m now able to use the computer by pointing a pen at the screen and clicking on it. Basically it’s just a matter of setting the Wiimote on a chair off to the side of the screen, connecting it via Bluetooth to the computer, and calibrating the pen. Then it’s possible to use the pen like a mouse.

Here’s Kyra playing around in Tuxpaint on the plasma screen:

My next project will be to connect all of this to a projector so we can use the wall as a whiteboard. The end goal is to use it in my second-grade science class.

Oh, and I’m also going to buy a pair of cheap gloves and attach an IR LED to the index finger, so I can use my finger instead of a pen. Way cool.
