1. A method of providing information about a real-world space, comprising the steps of:

  • (a) as the or each of at least one user moves through said space, virtual markers are deposited and stored to indicate associated locations visited by the user in the space, the virtual markers each having an initial strength value;

    (b) the strength values associated with the stored markers, either taken in location-dependent aggregations or individually, are caused to decay with time;

    (c) data about the current strength of the stored markers, either in aggregation or individually, is used to provide information relevant to use of the space.
