PROBLEM TO BE SOLVED: To dispense with the need to visit a WWW site for confirming a specific update position of the WWW site. SOLUTION: An information group that is a monitoring object is managed by a variable in a monitoring object information DB 19. A monitoring object operation part 16 registers, when positing information in a 3D space, the information to the monitoring object DB 19, and deletes, when deleting the information from the 3D space, the information from the monitoring object information DB 18. When the 3D space is periodically updated, a space generation part 15 examines, with respect to the information included in the monitoring object information DB 19, whether or not the information is updated from an updating time DB 18 and converts, when it is updated, the updating time or a numerical value calculated from the updating time to coordinates. The browser part 32 of a user terminal 3 arranges the information in the coordinates. COPYRIGHT: (C)2005,JPO&NCIPI
