A model of manual control during perspective scene viewing is presented, which combines the Crossover Model with a simplied model of perspective-scene viewing and visual cue selection. The model is developed for a particular example task: an idealized constant altitude task in which the operator controls longitudinal position in the presence of both longitudinal and pitch disturbances. An experiment is performed to develop and validate the model. The model corresponds closely with the experimental measurements, and identied model parameters are highly consistent with the visual cues available in the perspective scene. The modeling results indicate that operators used one visual cue for position control, and another visual cue for velocity control (lead generation). Additionally, operators responded more quickly to rotation (pitch) than translation (longitudinal).
