Experiment B results averaged for each controller with standard error bars (n = 7). (a) Completion rate (CR) refers to percentage of successful attempts during virtual hand posture matching task. (b) Movement time (MT) describes time to completion during virtual hand matching task. (c) Average electromyography (EMG) amplitude (AMP) is measure of effort based on root-mean-square average of EMG activity and is calculated as percent difference from subject average. Positive AMP describes more than average EMG activity. *p < 0.05. C1 = controller 1, C2 = controller 2, C3 = controller 3.
