I think a robotic hand would prove uselful for those who are handicapped. A hand with 5 individual prehensile digits would be even more preferable. What would be really neat though, is if motions and gestures could be programmed onto it and activated when reacting to electrodes that could possibly be placed on the outside of the skin.
