Effects of Scene Visual Characteristics on the Perception of Rotation Gains

Rotation gain is a crucial technique in Redirected Walking (RDW) for altering users' virtual trajectories. However, prior research [3] lacked a systematic exploration of how different visual character-istics impact users' perception of rotation speed. Therefore, this study proposes an investigation into this issue by designing eight VR scenes varying in visual density, spatial size, and realism. Through a within-subject study, the impact of these factors on the subjective detection of rotational speed was assessed. The results revealed significant differences in perceptual detection thresholds for rotation gains between room and landscape scenes, particularly in the lower bound of rotation gain thresholds.
