Soap is a pointing device based on hardware found in a mouse, yet works in mid-air. Soap consists of an optical sensor device moving freely inside a hull made of fabric. As the user applies pressure from the outside, the optical sensor moves independent from the hull. The optical sensor perceives this relative motion and reports it as position input. Soap offers many of the benefits of optical mice, such as high-accuracy sensing.

I really love this new design of the computer mouse. The video below is very intriguing and really makes me want to make my own version soon. Depending on just how functional it really is, I could see this blowing past the gyration mouse to be the most innovative mouse advancement in thirty years.
