The Cornell University Airmouse Initiative is a motion sensing glove with buttons on it that plugs into your computer to function as a mouse.
Many tasks that are performed on the computer require the use of both a keyboard on the mouse, and many people find it frustrating and awkward to have to switch back and forth between them. So, we've created what we believe to be the solution to this dilemma, as you can wear the glove on your hand while you're typing and then when you want to move the mouse cursor, simply push a button that is already on your hand and point your finger at the screen and move it around. The Airmouse is comfortable to wear, and does not significantly inhibit typing. It functions completely as a two button serial mouse, and even implements variable rate vertical scrolling.
