PDF: Effect of Reclining Angle on the Perception of Horizontal Plane for HMD Users

Abstract

In recent years, head mounted displays (HMDs) have become widely used among general users thanks to the release of low-cost and high-performance versions. It is expected that virtual reality (VR) experiences will often be performed in a relaxed posture, while sitting on a reclining seat at home or in the supine position on a bed in rehabilitation institutions. However, there is no clear knowledge on the subject of how humans perceive the horizontal plane of a virtual world while using HMDs in reclining postures. In this study, we investigated how the angle of the subjective horizontal plane changes in relation to the angle of the upper body in a reclining seat. As a result, we found that the angle of the perceived horizontal plane changes depending on the angle of the upper body, and the physical direction of gravity has little effect on this perception.
