Do turning visited routes in black maps into white promote sightseeing?

In this paper, we propose a new approach for promoting visiting various areas during a sightseeing based on the ”FUrther BENEfit of a Kind of Inconvenience” (FUBEN-EKI) theory. FUBEN-EKI is a theory such that an inconvenient system in some aspect enables users to obtain more hidden benefits than convenient systems. Familiar navigation systems lead tourists to time efficient routes, and so the systems may limit their opportunities for new discoveries during their sightseeing. It is supposed that if tourists walk freely in various areas then they will have more change to find new discoveries. To promote visiting various areas, we propose a blacked-out map: The map is hidden by a black filter initially, but only the area where the user moves becomes clear. Since the user cannot see the map of unvisited area, the user thinks that the unvisited area might have interesting sightseeing spots. Moreover, to make all of the area clear, the user have to go to all of the area on the map.
