Detecting Slow Changes in System Dynamics.

Abstract

Two experiments were performed under laboratory conditions to study the human operator's adaptive behavior in manual control of slowly changing system dynamics. In the first experiment, the dynamics changed from rate to acceleration control. In the second experiment, the control stick sensitivity either slowly increased or decreased from a standard level. Four subjects participated in each experiment. Tracking performance on a compensatory task demonstrated that the human operator lags in adapting to the changing system dynamics, but he does adapt when given sufficient time. As the rate of change increases, the human operator needs a larger change for detection and a decreasing judgment time to detect the changing system dynamics. (Author)
