Abstract:

The effect of multisensory cues 3-D, audio, tactile belt to overcome a vestibular illusion in a rotating Barany Chair was investigated. Seated subjects were rotated about their spinal axis Z axis from a standing stop to a predetermined velocity. The acceleration experienced by the subjects as they changed velocity caused their semi-circular canals to react which they sensed as a rotation. When the chair was slowed, or stopped, the direction of the acceleration cue reversed and the subjects sensed a false rotation in the opposite direction. This illusion, called the somatogyral illusion, can occur in flight. The purpose of this research was to see if multisensory countermeasures could be applied to the subjects that would reduce or eliminate the false rotation. The 3-D audio countermeasure proved to be successful in reducing the velocity of the chairs rotation and the tactile belt countermeasure produced the highest success rating among the subjects.
