In this study, we explore how spatial configurations can be reflected in determining the threshold range of Relative Translation Gains (RTGs), a translation gain-based Redirected Walking (RDW) technique that scales the user’s movement in Virtual Reality (VR) in different ratios for width and depth. While previous works have shown that various cognitive factors influence the RDW threshold, studies investigating the impact of environmental aspects on the RDW threshold with regard to the user’s visual perception were lacking. Therefore, we examined the effect of spatial configurations on the RTG threshold by analyzing the participant’s responses and gaze distribution data in two user studies. The first study concerned the size of the virtual room and the existence of objects within it, and the second study focused on the combined impact of room size and spatial layout. Our results show that room size, the existence of …
