Couple of days back, I found this very interesting project. This guy (Johnny Lee) creates a Touch Screen Whiteboard using Wiimote and an Infrared pen. Ideally, this would be more useful to do it using a laser pen and a webcam. I'll try to write a code for the same. But, you know, I'm a bit lazy. I can't set a deadline on this.



Here is the video folks for those who are interested: (Btw, I've set this one up at my home and it works nearly well. The resolution and stability of the camera becomes a bit of a problem though!)
