| Outline of Final Research Achievements |
Estimating not only hand motions but also their speeds from the surface electromyogram (sEMG) is required in order to operate a myoelectric prosthetic hand like human hand. In this study, we constructed an estimation system of types and speeds for six hand motions (wrist flexion, wrist extension, grasping, opening up, wrist supination, and wrist pronation) from multi-channel sEMG signals. Furthermore, we also conducted a system that can estimate joint angular velocities from multi-channel sEMG signals for handling numerous motions. Experimental results showed that both of the proposed systems achieved higher estimation accuracy than conventional methods.
