Mitigating VR Motion Sickness in Visual Sharing Based on Observer-Observed Coupled Movements

Abstract: Visual sharing via Virtual Reality (VR) significantly enhances skill transfer within complex industrial domains. However, sharing another's viewpoint can lead to severe motion sickness. Although many researchers have proposed numerous solutions to address VR sickness, few are specifically tailored for visual-sharing experiences. This study aims to propose the VR sickness mitigation method for VR visual-sharing experiences introducing Observer-Observed (Observer and Operator) Coupled Movements. This method can reduce the disparity between the body's movements and the visuals by field of view restriction and motion-compensated point rendering with observer-observed coupled movements in the visual-sharing system. Furthermore, this study experimented to verify the effects of the proposed method. The results indicate that using this method during shared viewpoints can reduce the sickness caused by perceptual and visual discrepancies to some extent without significantly impacting the observer's understanding of the content in the VR experience.
