Abstract

Communication between users not accessing a shared virtual reality space at the same time is realized. A client terminal sends a calling card and a mail. A hard disk drive of a mail server holds the calling card and the mail. When a user to whom the calling card and the mail are to be sent accesses the shared virtual reality space, the mail server transfers the calling card and the mail to the client terminal.
