Posture Matching Performance Over Time. The same KNN constructed from data collected at the “Week 0” KNN mark was used during posture matching evaluation in every session. Each data point is an average of 80 target hand posture trials from one session with the exception of the first KNN session which was 160 trials from two sessions, one at the beginning and one at the end of the day. The error bars represent the standard deviation of each day’s collected trials. The greater the Path Efficiency and less the Trial Time Used, the better the performance
