The subject of the project is the development, initiation and sustainable anchorage of mobile games to identify unambiguously landmarks, which support pedestrian navigation in space and allow public use.

Humans orient themselves and control their movements through their world by means of landmarks. Landmarks are meaningful markers of a way or a location. It makes sense, to employ landmarks as basic modules of navigation systems and location-based mobile applications.

Navigation systems are based traditionally on routes for car drivers. They do not use landmarks and are not transferable to pedestrian navigation. With the increasing use of GPS-phones the task arises, to integrate landmarks in route descriptions of navigation systems and location based mobile applications.

The problem is: the automatic generation of landmarks has limits. What and why something becomes a meaningful landmark, depends above all from the actor and the actor's activities. Locations, routes, landmarks further permanently change. The consequence is the automatic determination has to be complemented by human determination of landmarks. But it is almost unaffordable for small, middle-sized or even large companies to let humans determine landmarks unambiguously. However, humans do it voluntarily and for free, if the determination of landmarks becomes a game, makes fun and occurs playfully.

The project develops a solution for the determination of landmarks starting from the Human Computation Games approach, Luis von Ahn [Ahn & Dabbish 2008], and its further advancement in the area of mobile games for the determination of landmarks by the Geo-Informatics,

University Bamberg, by taking into account the borders of the automatic landmark determination, University Hannover. The project implements the solution in form of directly realizable applications. The proposal combines the development of the games and the technology, the initiation of mobile game cycles, which deploy the technology, the anchorage of these in a Living Lab for Mobile Entertainment in Bremen and the scientific modeling of the geospatial interaction.
