Figure 5From: Using visual feedback distortion to alter coordinated pinching patterns for robotic rehabilitation(a) Performance of a single subject on trial 21. The solid line represents the normalized position of the target line as a function of time, and the dashed line represents the normalized position of the index finger. (b) Performance of the same subject on trial 200. The subject has reduced the error of the index finger relative to the target line, but the lag between the target line and the path of the index finger has remained approximately the same.Back to article page
