Webcam based Whiteboard

I have been working on an IR marker tracking application using a webcam as acquisition device, when I found about Johnny Lee's low-cost whiteboard great idea based on the Nintendo Wiimote I knew I had to give it a try.

Using an IR pen and a commonly available webcam, it is possible to mimic the Wiimote Whiteboard application, though it requires a bit more processing.

actually.. whats grt with the wiimote whiteboard is the fps.. normally availaible webcams cant come close to that resulting in considerable delay which is evident in your video too...

@hanusingh, not sure whether you can refer to the wii remote update rate as fps, but it is true that it is a lot faster since there is no processing involved for the PC application.With a decent PC one can expect acceptable delay, my application is not optimized in any way, including those slow debugging messages being output to the console, but is a bit faster than other first version attempts.
