概要/Abstract

On the mobile devices, navigation services using the location information such as GPS are widely used. Thus, those services are mostly intended to lead the user to a goal set in advance. In the real space like a town or an exhibition hall, we often wonder around to find an interesting place to go. In this research, we define that type of navigation as ”browsing”. We propose an interface called ”Flat”, which represents other user’s activities on a radar screen.To realize the browsing, three design principles are applied: 1)social navigation, 2)ego-centric mapping, and 3)the analogy of the scent. In Flat, individual points and the history of the multiple users movements are used as an analogy to scent. The virtual scents could be composed of multiple features. The strength of the scent of each point is in reverse proportion to the distant from the user. Then, the scents are grouped into 8 directions and summed. Finally, the strength of the scent to the surrounding directions are shown. In this way, the direction which includes closer and stronger points are recomended.
