Study on the Influence of Delayed Vision Using Virtual Reality on the Performance of a Target Game

Abstract

Sports training and rehabilitation using virtual reality (VR) are attracting attention. However, there is a problem that VR training is subject to input and visual delays due to the high processing load. It is important to improve athletic performance through training even when there is a delay. Therefore, the purpose of this study was to investigate the effects of artificially added delays on athletic performance in an environment with visual delays. Specifically, we used VR to add delayed vision, and then played VR target game under this environment to investigate the effect of delay on target game performance as a two-dimensional ball landing position with the center of the target as the origin. The experimental results showed that the delay significantly affected the performance in the x direction. In order to clarify the effect of delay on the human motor system, we conducted a simulation using a model of the human brain during target game. The simulation results showed that the experimental results were reproduced for the x direction, and that the forward model was changed by the visual delay.
