-How’s it Work and What Conditions are Necessary?-
For this to work, all you need is a room with (at least) some light. The results will be best when the room lighting is even (no bright lights shinning from one direction onto the multitouch pad).
When you place you fingers on the surface, shadows are created where your fingers are. The webcam sees these shadows and sends the image to the tracking software which tracks the shadows as they move around. It’s really that simple!
