A study on cyber sickness reduction by oculo-motor exercise performed immediately prior to viewing virtual reality (VR) content on head mounted display (HMD)

The purpose of this study was to investigate the effect of performing an oculo-motor exercise, immediately prior to watching VR (virtual reality) content on HMD (head mounted display), on cyber sickness. Eight subjects participated in a test. The results were analyzed based on three categories of symptoms associated with cyber sickness (nausea, disorientation, oculomotor) to assess the effect of oculo-motor exercise on cyber sickness. Additionally, the Simulator Sickness Questionnaire (SSQ) test was used as a parameter for the evaluation. The proposed method resulted in a significant reduction in cyber sickness ( p < 0.01) in all the three groups. Therefore, the proposed method was effective in alleviating cyber sickness.
