Managing real-world and virtual motion

A US Patent was published for the technology presented in the IEEE Access journal and the ACM SIGGRAPH poster on redirected walking by Yashas Joshi and Charalambos Poullis.

TL;DR: Navigating large-scale virtual environments in room-scale physical spaces using natural locomotion is problematic since users will most certainly encounter obstacles, e.g. walls and furniture. We use a VR headset with an embedded eye-tracker to track where the user is fixated and continuously update the 3D content in their peripheral vision to cause a redirection. Users fail to notice the update due to inattentional blindness. Additionally, we update the entire scene when a saccade is detected. Using this technology, users can walk distances of more than 100m while confined in a 3x3sq.m. room.
