G-2-5 筋電信号と脳波信号を用いた上腕の動作推定

Abstract

An electromyogram signal is one of the commonly used input signals to control an electrical arm. Some estimation methods of the user's motion intention based on the electromyogram signals have been proposed in order to control electrical arms according to the user's motion intention. However, in the cases of above elbow amputees, the muscles which are used to generate the forearm and wrist motions are missing, and electromyogram signals of those muscles could not be measured. To control the forearm and wrist motions of an electrical arm for above elbow amputees, other input signals are necessary. In this paper, to control the forearm and wrist motions of an electrical arm, we estimate the target position of the hand based on the electroencephalogram signals, the shoulder and elbow angles.
