Visual information is the most important information that humans use to perceive their own movements. In this study, we investigated how the perception of our own movement changes when we walk with a more expanded field-of-view (FOV). To expand the visual field, we constructed an FOV expansion system using a wide-field head-mounted display (HMD), two omnidirectional cameras, and a control PC. Using this system, the human FOV could be freely expanded from 160 to 360° in real-time. The results of the experiment indicated that the greater the expansion of the FOV, the faster the subject perceived their own walking speed. In addition, there was one case wherein the faster the perceived walking speed was, the shorter the perceived walking distance was. These results suggested that FOV expansion could create the illusion of increased athletic performance.
