Minimum Torque Change Model Vs. Power Law for Elliptic Movements

This study compared between the minimum torque change model and the power law model, for human elliptic movements. In simulations, trajectories based on the two models were computed, at different movement velocities and joint viscosities. The computed trajectories, based on the power law model could reproduce the characteristics of actual human movements, better than the other model. The results suggest the criteria of computational simplicity, in addition to the optimization of smoothness in human motor planning.
