Abstract (in Japanese) (See Japanese page) 
(in English) In the field of AR, smartphones are often used for navigation, but since the hands are occupied and the immersive experience is compromised, it is preferable to use a stand-alone HMD for AR. However, AR navigation using HMDs is easily affected by the external environment, which inhibits immersion and realism. In addition, the only way to know the traces of a person who was there in the past is to view two-dimensional content, which does not provide a sense of presence or realism. In this research, we aim to implement an AR navigation system that enables interaction with avatars by eliminating factors that impair the sense of presence and realism. As a preliminary step, we investigated how to display avatars with a sense of presence, using HoloLens 2, and experimented with three levels of abstraction, each with motion, superimposed on the Keio University Shonan Fujisawa Campus. The results suggest that the avatar with the lowest level of abstraction and the appearance closest to that of a human being has a greater presence on certain questions. We also observed the "uncanny valley phenomenon," in which people feel fear and discomfort toward the Avatar when its appearance is closer to reality.
