Exploration of the Virtual Reality Locomotion Methods using Hand-tracking, Eye-tracking, and EEG

Abstract

Although recent developments in VR tracking technology have enabled VR to become more portable and convenient, VR must overcome limited traversable space to be used for more general purposes. Since future VR HMDs aim to embed bio-sensors, such as eye-tracking and electroencephalography (EEG), the present study investigates how bio-sensors could be integrated into VR locomotion and how usability could be improved. In this study, teleportation methods were developed by combining EEG, eye-tracking, and hand-tracking for location targeting and teleport triggering processes. In a static teleportation task, we compared the efficiency, accuracy, and usability of each method as well as the interactions between different combinations of methods. The experimental results verified that these locomotion methods were overall suitable for hands-free VR contents, and revealed relative strengths and weaknesses of each method for the future approach.
