ABSTRACT
Teleportation is a popular locomotion technique that lets users safely navigate beyond the confines of available positional tracking space without inducing VR sickness. Because available walking space is limited and teleportation is faster than walking, a risk with using teleportation is that users might end up abandoning walking input and only relying on teleportation, which is considered detrimental to presence. We present redirected teleportation; an improved version of teleportation that uses iterative non-obtrusive reorientation and repositioning using a portal to redirect the user back to the center of the tracking space, where available walking space is larger. A user study compares the effectiveness, accuracy, and usability of redirected teleportation with regular teleportation using a navigation task in three different environments. Results show that redirected teleportation allows for a better utilization of available tracking space than regular teleportation, as it requires significantly fewer teleportations, while users walk more and use a larger portion of the available tracking space.
