車椅子シミュレータにおける固定格子表示によるVR酔い軽減の検討

抄録

This paper describes a method for reducing VR sickness in a wheelchair simulator. Our previous study developed a wheelchair simulator that can evaluate and examine barrier-free houses for wheelchair users at the design phase. However, this simulator had a problem of VR sickness caused by the discrepancy between the sensation obtained from the virtual space and the sensation predicted from past experiences. In particular, it was known that VR sickness occurred frequently and strongly during rotational motion. Furthermore, among rotational motions, VR sickness occurs most easily during yaw rotation. Therefore, this paper proposes two methods to reduce VR sickness by focusing on the yaw rotation. To verify the effectiveness of the methods, an experiment was conducted on a subject.
