"This report describes an experiment in which the subjects, using an aircraft-type stick control, attempted to keep the pointers on a simulated cross-pointer display on center in spite of random disturbances. Both the difficulty of the problem, expressed in terms of rate of pointer motion, and the motion relationship between control and display were varied. The effects on performance of these variations, singly and in combination, were assessed. The results indicate that: (a) tracking performance improves as the rate of movement of the pointers decrease; (b) the motion relationship is superior to its converse; (c) no significant interaction effects result from combinations of rates of pointer movement and direction of motion relationship; (d) practice extending over 140 trials, each of 50 seconds duration, was not sufficient to nullify the effects of an adverse motion relationship or of higher rates of pointer motion."--Abstract.
