Intelligent recognition system for hand gestures

In this article a new recognition system for hand gestures developed for the purpose of controlling active hand prosthesis is presented. The recognition system allows for the measurement and classification of muscle contractions around the lower arm. The system associates muscle contractions to corresponding finger grips of an electrically controlled prosthesis. Thus, a user can control a hand prosthesis by contracting the muscles of his arm through making hand gestures. This contribution describes the setup of the system and a first analysis of the stability and precision for recognizing and differentiating discrete hand gestures.
