Outline of Final Research Achievements	In a shared space where pedestrians and mobility vehicles can pass freely, they come across each other in any direction, they should pay attention to every directions. In such case, external HMI (eHMI) enables the transmission of state and intent information from the vehicle to the rest of the traffic participants are useful. In this study, we developed a technology to construct a shared space where pedestrian space and vehicle space are physically independent and integrated using VR/AR technology as an experimental environment without collisions with mobility vehicles. As an external HMIs (eHMIs) that mutually communicates with conditions of pedestrians and vehicles with graphical information was developed. The effectiveness of presenting three-dimensional information such as the expected area of one's own presence, information on the possibility of collision, and information on the movement of the effective field of view was suggested as an element required for eHMI.
Free Research Field	ヒューマンインタフェース
Academic Significance and Societal Importance of the Research Achievements	多人数参加の歩車共有空間において、3次元eHMIの有用性が示唆されたことは、今後のインタフェース普及において、ARグラスなど情報提示機器による移動支援の可能性を示す成果と言える。一方でこのことはARグラスを持たないユーザを阻害することを直ちに意味するものではなく、持たないユーザがいるという情報を共有することで全体としての円滑な通行を実現する上でも重要と言える。
