Eye movement characteristics in visually induced motion sickness

Abstract

Visually induced motion sickness (VIMS) is a phenomenon that causessymptoms similar to motion sickness that occur during video viewing.Various explanations have been proposed for the cause of VIMS, but theexact reason is still an open problem. We focused on characteristicsof eye movement during video viewing as one of the causes of videosickness, and measured eye movements during viewing to videos withdifferent spatial frequencies. The degree of sickness was measuredusing SSQ (Simulator Sickness Questionnaire). As a result of eyemovement analysis, subjects with a high SSQ score tended to have a bigeye movements. On the other hand, eye movement distance was not largein subjects with low SSQ score. The phenomenon was remarkable in videothat seemed to have a high spatial frequency. In the future, we planto increase the number of subjects and conduct more precise experiments.
