Virtual reality (VR) allows users to be placed in a computer-generated environment and provides realistic visual feedback through motion tracking, high refresh rates, and a stereoscopic display [16]. VR presents a new opportunity to provide immersive experiences with applications to job training, entertainment, social interactions, and therapy and rehabilitation. One important aspect of providing users with a comfortable, immersive virtual experience is granting users the ability to freely explore the virtual environment (VE) [5, 6, 30]. Due to the importance of exploration for virtual experiences, it is crucial that we develop locomotion interfaces that provide the best user experience.
