So you want to play guitar like Jimmi Hendrix or Carlos Santana, but you just don't have the skills? Don't worry, the Japanese have a solution for you. PossessedHand
, is a device being developed by the University of Tokyo
, and Sony Computer Science Laboratories
, that can move your fingers into the proper positions to play musical instruments. The device electrically stimulates the muscles in the forearm that play a role in moving the fingers, without the users mind instructing the hand to move.
PossessedHand consists of a belt, worn around the user's arm that contains 28 electrode pads. These electrodes flex the joints in the hand, including the joints that enable the fingers, thumb and wrist to bend. Though information about the exact mechanism is spare, it seems as though electrical impulses stimulate the muscles in the forearm, which power the movement of the connective tissues (tendons and ligaments) that allow the joints in the hand to bend.
User's are aware that their hand is moving, however they do not have control over how it moves. Unlike other devices that use electrodes to control hand movements, PossessedHand is non-invasive and doesn't require the electrodes to be embedded in the skin.
