Colocation for SLAM-Tracked VR Headsets with Hand Tracking

In colocated multi-user Virtual Reality applications, relative user positions in the virtual environment need to match their physical tracking space. A mismatch between and real might lead harmful events such as collisions. This paper examines three calibration methods that enable scenarios for SLAM-tracked head-mounted displays without an external system. Two of these methods—fixed-point marked-based calibration—have been described previous research; third method uses hand capabilities is novel. We evaluated accuracy experimental procedure with two Oculus Quest devices. The results evaluation show our novel tracking-based provides better consistency while at same time being easy execute. further discusses potential all methods.
