-What's a 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.
-How's it Work?-
--------------------------------------
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.

1/8in, but anything thick enough to sustain pressure is ok.

that box looks huge. Can you make it slimmer and achieve same results?

yeah, you can make it smaller. It can be almost any size you want as long as the camera can see the surface.

It wouldn't be comfortable. You'd have to keep your hand high off the paper as you draw so that the webcam doesn't pick up your hand's shadow.
