hi, i a video in youtube that explains how to make a multitouch screen with a wii remote and i was wondering if you can make the same but with an ir webcam/video camera. [and i have a probably stupid question but how to make a 4 point calibration in windows vista...} {Sorry for the bad english but I'm portuguese}


yes you can :simple answer:

There's a much easer version that you can build, I'll post a link when I can find it.

You can search "whiteboard" or "touchscreen" on this site to see if any of those designs will help. The links to the software they use may give you ideas. Good luck.
