EFFECT OF PREDICTABILITY OF IMPOSED VISUAL MOTION ON THE OCCURRENCE OF MOTION SICKNESS

by Otten, Edward W

Abstract (Summary)
The prediction and prevention of motion sickness in virtual environments will be critical to the acceptance of virtual environments as a training tool. The postural instability theory of motion sickness suggests that motion sickness results from prolonged exposure to situations where stable control strategies cannot be achieved. In the current research the extent to which the predictability of visual stimuli influences the occurrence of motion sickness was examined. The unpredictability of a complex stimulus versus a simple stimulus did not result in an increase in sickness incidence. Postural motion did show differences between sick and well participants during baseline trails, suggesting possible predisposition, and velocity successfully classified participants into sick and well groups, which may be useful in sickness prediction. Examination of the power of the postural motion revealed an ability of participants to adapt to a simple stimulus versus a relative inability to adapt to a complex stimulus.
