Abstract

The purpose of this study is to investigate the display fatigue quantitatively when operating 2D and HMD-based 3D VR bicycles. Though it is generally accepted that the display fatigue induced by 3D VR is greater than that induced by 2D VR, there have been few studies which attempted to measure the display fatigue scientifically. The subjective degree of cybersickness and quantitative flicker fusion frequency (FFF) were measured in twenty subjects (Male 10, Female 10) before and after they operated 2D and 3D VR bicycles for 5 min. Two dependent variables affected by the 2D and 3D VR displays were analyzed and compared statistically based on scientific evidence and research. This study showed that 3D VR resulted in a significantly higher cybersickness rate and a significant lower FFF rate than 2D VR. Given the current propensity to couple VR techniques with exercise equipment, it seems appropriate to verify the general beliefs through scientific methods and experimental measures such as the FFF and cybersickness questionnaires.
