If a device can control human hands, the device can be use- ful for HCI and tangible application’s output. To aid the controlling of finger movement, we present PossessedHand, a device with a forearm belt that can teach when and which fingers should be moved.
Please also see the article by New Scientist.
PossessedHand controls the user’s fingers by applying electrical stimulus to the muscles around the forearm. Each muscle is stimulated via 28 electrode pads.
Muscles at different depths in the forearm can be se- lected for simulation by varying the stimulation level. PossessedHand can automatically calibrate the system for individuals. The automatic calibration system estimates rela- tions between each electrode pad, stimulation level and mus- cle movement. Experiments show that PossessedHand can control the motion of 16 joints in the hand.
We also present an application of this device to help a beginner learn how to play musical instruments such as the koto.
We are looking for partners who are interested in PossessedHand applications including:
– Rehabilitation support
– Learning support
