Figure 6From: Effects of kinematic vibrotactile feedback on learning to control a virtual prosthetic arm Maximum turn-around virtual arm angle after it passed the waypoint. A larger angle indicates that the arm moved further past the waypoint. Both the group mean (A) and average standard deviation across trials (B) are shown. Data are from late-practice (Block 4). The waypoint was at 45°, indicated by a dashed line in A. *Significant differences between groups.Back to article page
