The Effect of Screen Fluctuation Rate Changes in a VR Environment on Users' Feelings of Sickness

Abstract

The purpose of this study is to investigate the impact of the rate of screen variability in a VR environment on eye fatigue and the feeling of sickness, and to explore methods for reducing VR-induced discomfort. Experiments were conducted using a VR game in a controlled environment. The incidence of screen sickness during character movement and at different resolutions was measured, and physiological indices were recorded. The frequency of VR sickness increased when the rate of screen fluctuation was high or the resolution was low, and was also correlated with changes in the LF/HF ratio. It was shown that visual optimization may contribute to the reduction of VR sickness.
