Redirected Walks Through Hazardous Environments: Detection Thresholds of Curvature Gains in 360 Video and 3D Telepresence Setups

This paper investigates the application of redirected walking techniques in the context of a virtual reality (VR) telepresence system designed for remote control of a maintenance robot within hazardous environments. We estimate detection thresholds for curvature gains in two distinct environments: a 360-degree video-based VR setup and a three-dimensional (3D) modeled environment. Building upon prior work that focused on translation and rotation gains in 360 video-based VR, this research explores curvature gains in 360 video-based VR. Moreover, we compared results to detection thresholds of 3d modeled environments. Our findings reveal differences in detection thresholds between the 360-degree video and 3D modeled environments, with the latter displaying a larger shift of thresholds for curvature, and therefore offer insights into perceptual aspects and limitations of human sensory system.
