Real-World Distance Reduction in a Virtual Reality-Based Wheelchair Simulation on Flat Surfaces
Pages 438 - 448
Abstract
A virtual reality (VR)-based wheelchair simulator based on a combination of motions attainable by an electric-powered wheelchair and vection-inducing videos displayed on a head-mounted display has been proposed for patient rehabilitation and training. This simulator requires the actual physical distance traveled by the wheelchair and the distance traveled by the wheelchair in the virtual environment to be the same. This requirement limits the locations where users can use this simulator. We clarify the relationship between these distances and aim to reduce the physical distance required to perform VR-based wheelchair simulations. To this end, we conducted an experiment whereby participants drove a wheelchair on a flat ground at a constant speed and at a decreasing speed for 8 m. The experimental results showed that the required physical distance can be reduced by 30% and 20% using the constant speed and deceleration approaches, respectively. The results of this study are expected to contribute to the development of wheelchair simulators that require less space.
