Abstract(in English) | We investigate trajectory planning for a time-minimizing task in human reaching movements. Using computer simulation, Suzuki et al.confirmed that the minimum-movement-time trajectory concaves toward a body and its velocity profile has two peaks. Suzuki et al.observed in psychophysical experiments that subjects generated roughly straight hand paths with bell-shaped velocity profiles in the time-minimizing, task, but they performed a few reaching trials. It was possible that the subjects could not produce the optimal trajectory owing to the lack of training. In the current work, subjects were asked to continue quick reaching movement for 7days. We found that the subjects always generated roughly straight hand paths with bell-shaped velocity profiles in the time-minimizing task for 7 days. Moreover, we asked other subjects simple point-to-point movements and taught the subjects movement duration after every trial. In the experiments, we found that the subjects always generated roughly straight hand paths with bell-shaped velocity profiles for 7 days. These features can be reproduced by the minimum commanded torque change model which requires the smoothness of motor command. |
