ABSTRACT:
A method and apparatus are disclosed for providing information about a real-world space such as an exhibition space. In a preferred embodiment, users visiting a space are equipped with mobile devices in communication with a service system. The mobile devices are arranged to deposit virtual markers with the service system as the users progress around the space. These markers are stored used to provide trail information concerning use of the space. An operator provided with an interface to the service system can directly modify the stored markers or their significance to thereby modify the trail information.
