How to Make a Cheap Multitouch Pad - MTmini

How to Make a Cheap Multitouch Pad - MTmini A Multitouch Mini, MTmini for short, is a cheap, small, portable multitouch pad. It can be used for all different purposes including: drawing, OS navigation, multitouch operation, games, entertainment, experimentation, and more. I created the Multitouch Mini to show people how something that seems complicated or 'magical' can be made simply and at low cost. When you place your fingers on the surface, shadows are created where your fingers are placed. The webcam sees these shadows and sends the image to the tracking software which tracks the shadows as they move on the touch surface (paper).

All you need is a room with (at least) some light; a dark room will not work. Even room lighting gives the best results. Lights shinning from multiple directions onto the multitouch pad gives better results than lights from one direction. and is it possible to with 2 webcams make touch-screen??(just to recognize fingers and pen)
