Hand trajectories and kinematic parameters in different WS conditions. Hand trajectories in the coronal plane for C1 and C6 (left panel). Kinematic parameters of hand motion (right panel). Ac - accuracy, TD - target distance, MPV - maximum peak velocity, NJ - normalized jerk. For each parameter, each bar height represents the average value across subjects and targets and the error bar represents the standard error. A grey scale is used to show the results for different WS conditions, as reported in the legend.
