Abstract
Abstract The mobile object data storage unit of the management center manages and stores the positional information and the attribute information about a number of unspecified mobile objects such as persons, creatures, objects, etc. moving outdoors, etc. Upon receipt of the detection condition of the position and the attribute of another mobile object from the terminal unit, the retrieval unit searches the mobile object data storage unit, and displays a list of corresponding mobile objects on the requesting terminal unit. The guiding information computation unit computes the guiding information to a detected mobile object selected by the requesting mobile object terminal unit depending on a predetermined privacy setting level, and transmits the guiding information to the requesting mobile object terminal unit.
