The study was designed to determine interaction effects of central tracking performance and performance on variously located toggle switch controls. Subjects were required to operate toggle switches located in various positions to their left while maintaining control of a primary tracking task. Performance times for toggle switch operation and absolute integrated error scores corresponding to each toggle switch location were collected and analyzed. The results indicated that a Variation of toggle switch location had no effect on tracking performance. b Vertical displacement of toggle switch controls affected only the reach time, while angular displacement affected only the manipulation time. The results of this study were compared with the results of a study completed earlier which used a centrally located fixation point rather than a tracking task. With the tracking task substituted in place of the fixation point, the reaction time the time to release the starting switch to secondary control operations decreased. Author
