LABORATORY AND MOVING-BASE SIMULATOR EXPERIMENTS ON SPEED AND ACCURACY OF VISUAL AND WHOLE-BODY MOTION PERCEPTION

Abstract In a roll tracking task with an artificial horizon as the single instrument, changes in human operator control behaviour and more accurate performance were found due to addition of cockpit motion and visual motion in the peripheral field of vision. In two subsequent, stimulus-response type experiments, on speed and accuracy of motion perception, under similar experimental circumstances, data were obtained which explain a number of effects found in the tracking task experiment. The main finding is that cockpit motion improves tracking performance due to a faster motion perception process.
