Abstract

PROBLEM TO BE SOLVED: To provide the sharable virtual reality space for an infinite number of users on a world scale. SOLUTION: When an URL(uniform resource locator) is sent from a client terminal 13-1 through a network 15, an information server 10 and a mapping server 12 inform the client terminal 13-1 of a three-dimensional virtual reality space consisting of only basic objects that do not change in basic state and the IP (internal protocol) address of the common-user server 11. According to the obtained IP address, the client terminal 13-1 accesses the common-use server 11, which then transmits information regarding avatas (update object) representing the users of other client terminal 13-2 and 13-3, so that a virtual reality space on which the avatas are reflected. Therefore, the three-dimensional virtual reality space can be shared without giving any alteration to the existent Internet.
