An experimental and analytical study was undertaken jointly by the Aerospace Medical Research Laboratory and Bolt Beranek and Newman Inc. to test a model for the pilot's use of roll-axis motion cues. Principal experimental variables were the presence or absence of simulator motion, the nature of the external disturbance, simulated vehicle dynamics, and the nature of the motion cues provided during moving-base simulation. The effects of motion cues on closed-loop system performance and pilot response behavior were qualitatively and quantitatively dependent on the details of the tracking task. The optimal-control model for pilot/vehicle analysis provided a relatively task-independent framework for accounting for the pilot's use of motion cues. The availability of motion cues was modeled by augmenting the set of assumed perceptual variables to include the position, velocity, acceleration, and acceleration rate of the roll-axis simulator with the exception that position information was omitted when the roll tilt cue was absent. Results were consistent with the hypothesis of attention-sharing between visual and motion variables. (Author)
