Conventional EMG(Electromyograph)-contorolled prosthetic hands take almost one month until users master the control of hand movements. The EHW controller, however, succeeded in reducing such rehabilitation time drastically (about ten minutes!). The EHW for the hand adaptively synthesizes a pattern recognition circuit which is tailored to each user, because EMG has strong individual differences. A gate-level EHW LSI is developed for this EMG hand. This hand will be commercialized this year.
