Goals

The goal is to use your hand as a pointing device (like the mouse) using a webcam. Just move your hand to the right to make the pointer on the screen go to the right.

Novelty

It's cordless. It's optical. Nothing new so far, but it also requires no battery charges, and you can never loose it! (Even if you did, you can still use the rest of your body). It's useful in situations where no room is available for a mouse, or in 'extreme conditions' where a mouse might break down easily.

Challenges

Designing the hand/mouse movements to be natural and intuitive.
