Abstract
The present invention relates to a hand motion control system and a control method thereof, and more specifically, to a hand motion control system for a myoelectric hand, and to a control method thereof. The system enables not only grasping motions for grasping an object, but also the expression of hand gestures expressing emotions or intent, based on a limited myoelectric signal transmitted via two myoelectric sensors provided on the myoelectric hand. Furthermore, the system enables a wide variety of hand postures and grasp types that are determined by the position of a thumb, which can be changed by a user, thus easily expanding the range of applications of the myoelectric hand.
