The Dynamic Seat as an Angular Motion Cuing Device

Abstract

The role of advanced motion cuing devices as an alternative to platform motion simulation has been debated for several years. The dynamic seat nas been shown to be an effective device for providing task-critical onset motion information on the roll axis, provided that proper attention is given to the drive laws. Since it is difficult to extrapolate the benefit derived from the dynamic seat to an operationally-realistic task environment, the dynamic seat project has initiated a series of studies that lead to motion cuing in a multi-axis aerial refueling task. In this experiment, twelve subjects controlled a compensatory tracking task in roll only, pitch only, and a combined task condition. Operator performance was evaluated between four levels of drive algorithm across axis. Significant differences in tracking performance were found both within axis and between algorithm. In addition, the rank ordering of the treatment means were consistent with previous findings in our laboratory.
