Whenever a tourist is going to visit a point of interest, PSiS Mobile shows detailed information about it (Fig. 3c). In this interface the tourist can see point of interest information, give feedback about the recommended sight (which is used to evolve tourist stereotype and preferences) or call, send email or go to the sight website. A map is also available (Fig. 3b) to help user orientation, which gives the directions from the user location to the point of interest.
