A COMPARISON OF THREE TYPES OF MANUAL CONTROLS ON A THIRD-ORDER TRACKING TASK,
Abstract
Three types of control levers--the spring-centered-displacement control, the on-off control, and the pressure control--were compared on a third-order compensatory tracking task. Based on an analysis of the control transfer functions, the predicted ranking of the three controls are: (1) pressure, (2) displacement, and (3) on-off. The results of a study in which five subjects tracked six trials with each control for 18 sessions were as follows: The data at the beginning of training indicated rankings of (1) pressure, (2) on-off, and (3) displacement. However, the data taken during the latter sessions ranked the controls as predicted, although the difference between displacement and on-off was not statistically significant. Differences in results between early and late training and comparisons of these results with other studies are discussed. (Author)
