The Keyglove is a portable Arduino-powered glove that uses touch combinations to generate keyboard and mouse control codes using only one hand. Once learned, the glove can easily be used without looking, making it perfect for embedded/wearable environments. The glove is thin and light, built to allow other activities (such as writing or driving) without being in the way.

nice MEGA-based project. Have a look at the similar devices page to have a nice compairason of similar project online with different hardware solutions.
