ENI: Quantifying Environment Compatibility for Natural Walking in Virtual Reality

Abstract

Figure 1: A visualization of our Environment Navigation Incompatibility (ENI) scores for physical environment paired with three different virtual environments with increasing environment area. Our metric is used to accurately quantify whether it is possible to compute a good mapping between the geometric layouts of these environment. We sample points across the virtual environment to represent the user's position (shown as colored circles) and compute the corresponding point in the physical environment based on comparing the local neighborhoods. Overall, our metric helps us to determine which regions or subsets of the VE are more compatible with the PE. Through this visualization, we can see which regions of the VE are more or less compatible with the PE.
