Mathematical models of human operators in simple two-axis manual control systems

An application of continuous parameter optimization techniques to the synthesis of a model of human tracking behavior in a simple two-axis task is presented. Considerable emphasis is placed on the measurement of performance criteria for estimating the relative difficulty of single-axis and two-axis tasks as well as for evaluation of the validity of mathematical models. It is shown that the modeling technique can be used to yield a quantitative indication of the degree of cross coupling between axes introduced by the operator.
