摘要

PROBLEM TO BE SOLVED: To enable the information acquisition and retrieval of system registrants with each other in an actually visible world. SOLUTION: A communication control section 16 sends the position information with time and attribute information relating to a user from a user terminal 1 to a center 2 at every constant interval of time. When an acquisition request for the information on another user is made from the user in a user information management section 21, whether the information provision for the information acquisition request is okay or not is determined according to the access right level relating to each of the information of the user. In the case of the information provision okay, the user sending the acquisition request is provided with the information. In a map information management section 22, the structures where the respective users exist or the structures nearest the users are determined in accordance with the position information of the respective users. A label information forming section 23 forms the user position information for teaching the presence of the users within the structures or near the same to the respective users and adds the information to the label information. The label information is displayed in superposition on a display screen by the label information output sections 18 of the respective user terminals 1.
