Soap: a Pointing Device that Works in Mid-Air
Patrick Baudisch, Mike Sinclair, and Andrew Wilson

I found this interesting idea in the CHI2007.
The idea is to take out the optical sensor from your wireless and optical mouse and to directly put it in a lovely and silky hull. Then, instead of using your desk as a reference for the optical sensor of your mouse, the new reference is the hull, and you just need to move it around the sensor to give it the direction, the position and so on. You can now use it to play sitting in your sofa or walking when you make a presentation...
