Motion cues in man-vehicle control : effects of roll-motion cues on Human Operator's Behavior in compensatory systems with disturbance inputs.

The human operator's use of roll-motion cues is investigated for man-vehicle control in a compensatory tracking task with a disturbance input. Extensive data for the human operator’s describing function are taken for a wide range of vehicle dynamics under conditions of visual cues only, roll-motion cues only, and simultaneous visual and roll-motion cues. Addition of roll-motion cues to visual cues permits the human operator to increase his phase lead at frequencies above 3 rad-s.
