Revolutionary Gadget: Soap - The Mid-Air Mouse

Soap puts a new twist on tradional optical mice by adding mid-air functionality. This technology is “based on hardware found in a mouse” and “consists of an optical sensor device moving freely inside a hull made of fabric.” Video demonstration look at here.

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
