This setup is used for scientific study of how the human brain processes visual and equilibrial information simultaneously. This in turn can be used to optimize the combination of simulated images and movements so that the test person can no longer distinguish them from actual movements. Up to now no solution has been found for this problem in con-ventional driving and flight simulators in spite of considerable technological research and financial outlays. In one concrete experiment, for example, an attempt was made to determine the sensory stimuli which are most important for helicopter pilots when trying to keep a helicopter stationary and stable in the air ("hovering"). A realistic physical model of heli-copter navigation controls was installed for this purpose on the movement platform, along with the corresponding navigation instruments. Both experienced helicopter pilots and lay pilots participated in the experiment.
