Abstract
A system for providing information about physical entities to users includes an information server accessible to a plurality of user-held receivers. An exemplary server has access to characteristic accessibility data for candidate physical entities. The server receives a user's request for information about physical entities of interest (which may be mobile), including the user's search domain relative to the user's location (the user may also be mobile). The search domain does not necessarily require the user to provide a network address of, or perform a keyword search for the networked data pages of, the physical entities of interest. The server determines which (if any) of said candidate physical entities satisfy the request, and reports to the user at the receiver over an electronic network.
