| Abstract(in English) | We investigate trajectory planning for a minimum-movement-time task in human reaching movements. Using computer simulation, we confirmed that the minimum-movement-time trajectory considerably concaves toward a body and its velocity profile has two peaks. By executing psycophysical experiments, we found that the subjects generated roughly straight hand path with a bell-shaped velocity profiles. These features can be reproduced by the minimum-torque-change criterion that requires the smoothness of arm movements. We confirmed that the human could generate minimum-movement-time trajectory by specifying via-point and giving some instructions based on optimal torque profiles. The experimental results suggest that the brain cannot calculate the optimal trajectory according to the performance index except for the smoothness. |
