Abstract
Previous investigations of the effectsw of control-display (C/D) time delay on performance of continuous tracking systems have all demonstrated a decrease in system performance with increasing delay. A rational analysis of the joint effects of C/D gear ratio and exponential time delay suggests that the effects of increasing exponential delay depend on the particular C/D ratio employed. The present study was designed to demonstratethis interaction between the effects of C/D ratio and exponential time delay on the performance of a two-dimensional tracking task.The experimental results verified the predicted interaction. More specifically, it was demonstrated that with the "highest" C/D ratio (where a given control input produced the smallest display change) increasing delay effected a monotonic degradation in system perfomance. But, with the "lowest" C/D ratio (where a given control input produced the largest display change) increasing delay effected a monotonic improvement in system performance. With an intermediate ratio system perfomance first increase and then decreased with increasing delay.
