Quantitative examinations of trajectory planning criteria in multijoint movement - TOPS model

摘要

We examined the optimization models which explain the spatio-temporal features of hand trajectory. The hand trajectories predicted by the minimum torpue change model, the minimum elastic torque change model, and the TOPS(Task Optimization in the Presence of Signal-dependent noise) model were compared with the actual trajectories. In this paper, we analyzed actual and predicted trajectories for point-to-point movement within a wide range of the workspace in the horizonal plane. Quantitatively and statistically, our results indicated that the TOPS model's prediction have similar feature to the actual.
