Task space (left) and null space (right) components of subjects’ trajectories in hand space, H, across four days of training. G.S.U.: Glove Signal Units. Subjects in both the vision and no-vision groups reduced task space motion (shorter cursor trajectories on the screen) and null space motion (movement of the fingers that does not contribute to the motion of the cursor). More marked decreases were observed in null space excursion. Error bars are 99% confidence intervals. (Modified from Mosier et al. 2005)
