Use of Electromyogram Information to Improve Human Operator Performance.
Abstract
This research was conducted to investigate the effects of electromyogram (EMG) biofeedback on learning and performance of a compensatory hand-eye tracking task. A total of twenty male subjects took part in the experiments, with each participating in at least 48 scored tracking runs on the Roll Axis Tracking Simulator. The subjects were divided into three groups. The control group received no biofeedback, the first experimental group received biofeedback relaxation training and biofeedback while tracking, and the second experimental group received biofeedback relaxation training only. Comparisons across the three groups showed significant differences in muscle tension levels, but no significant differences in performing the tracking task. Analysis of scores from each subject showed learning to have the most significant relationship to score, and demonstrated the log/log nature of the learning curve. When averages were taken across all subjects, 98 percent of the variance in logarithm of score was accounted for by the relationship with logarithm of run number. (Author)
