| Outline of Final Research Achievements |
This work proposed a dual-arm task model for controlling myoelectric prosthetic hand with healthy limb in a daily life and realized a training system for the proposed prosthetic hand with the task model. The position and posture information of each arm is extracted from inertia measurement units attached to both arms simultaneously with the measurement of electromyograms signals using electrodes, enabling discrimination of the state of each arm as well as the discrimination of the hand motions used for prosthetic hand control. By estimating the task to be performed based on the state of each arm, the discrimination of the hand motions can be assisted according to the estimated state and cooperative task between the myoelectric prosthetic hand and the healthy limb can be performed with high accuracy.
