In recent years our lives have become more convenient with the abundant information being provided by our information society. We utilize that abundant information in living more effectively. A similar thing could be said about sightseeing. For example, tourist navigation systems have many features that allow the most suitable route to a destination to be displayed, similar to car navigation systems. However, there is a need to incorporate accidental encounters so that walking type sightseeing can be reviewed. This study does not support effective sightseeing but instead supports sightseeing that can be leisurely enjoyed. This study emphasizes “a sense of fun” and suggests a tourist navigation system that intentionally limits route information and induces accidental encounters. Or more concretely a navigation system was experimentally created in which the map around you disappears with movement. The effectiveness of it was then tested in assessment experiments utilizing a subject.
