The Sloped Shoes: Influence Human Perception of the Virtual Slope

At present, there is little research on redirected walking in the direction of the slope. In this study, people were allowed to walk uphill or downhill in virtual environments by changing the slope of users' shoes, while they walked on a flat wooden board in physical environments. We can explore the impact of the shoe slope on users' perception of walking uphill or downhill in the virtual world. We find that the slope of the shoes affects participants' perception, increasing their sense of realism when walking uphill and downhill in the virtual world. With increasing or decreasing the shoe slope, participants' perception of the possibility of walking uphill or downhill will also change and establish corresponding detection thresholds.
