PossessedHand controls human hands for human-computer interaction (HCI). By applying electrical stimuli to the forearm muscles, it directs the motions of 16 finger joints and informs appropriate timing of finger motions. It consists of a micro-controller and two forearm belts, which have 28 electric pads. Each pad stimulates a specific muscle set. Controlling the muscles requires special system calibration because stimulation location, intensity, and timing are different for each person. This demonstration introduces a musical application in which users wear a data-glove to interact with a graphical interface.

The system is intuitive. No special knowledge or training is required to use PossessedHand.
