The assessment of motion sickness induced by sensory conflict and posture instability

Abstract

The aim of this study is to analyze and evaluate the factors of motion sickness for the HMD virtual reality system with six-axis dynamic platform. The research team would like to explore the effects of duration of simulator use, virtual object acceleration, degree of control, and user training on motion sickness. According to literature review, the research team constructed the hypotheses of this study from the postural instability theory and the sensory conflict theory. In order to efficiently understand the perception of motion sickness, the research team makes use of the Fast Motion Sickness (FMS) scale to assess the level of motion sickness of subjects. Experimental results show that the duration of simulator use, degree of control, and user training have significant impacts on motion sickness. However, virtual object acceleration does not have an impact on motion sickness.
