Target positions and outcome measures. A: Error between target and reached position (control accuracy) when adjusting the wrist; B and C: Optimal and generated paths and end-point errors for hand and wrist, respectively. Trial time as well as optimal times (topt1 and topt2) to adjust each DoF are annotated on the x-axes.
