Abstract
In this study, we analyzed fixation eye movements immediately after watching certain length of movie contents which contain some factors to induce motion sickness. Motion sickness is defined as nausea, dizziness, vomiting and related symptoms caused by repetitive viewing of highly tremble movies. This symptom is caused by visual exposure; however, there is no evidence that motion sickness affects the dynamics of fixation eye movements. We apply a microsaccade rate analysis, a fluctuation energy analysis, and a random walk analysis to fixation eye movements for the purpose of evaluate the effects of motion sickness on the behavior of subjects objectively. The results show that the microsaccade rate and the fluctuation energy defined by root mean square of eye movements increase, and the dispersion of two-dimensional fixation paths varies widely in connection with deterioration of the symptoms. These results suggest that fixation eye movements could be a quantitative measure of motion sickness.
