The core of soap is an optical sensor. The core can rotate freely inside soap’s elastic hull. While pointing, users cause soap’s core to rotate by applying off-axis pressure. The relative motion between core and hull is picked up by the optical sensor inside the core.

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. We have tried soap for a variety of application scenarios, including wall display interaction, Windows Media Center, slide presentation, and interactive video games described in this list of example scenarios.
