Abstract: In an information exchange system in which a user terminal is connected to a network, the system is capable of transmitting and/or receiving messages via the network. A display area displaying messages transmitted and/or received can be increased with an increase in the number of networks connected, thereby causing the efficiency of processes due to reduction of the display area to deteriorate when such a display area is used simultaneously with other applications. The present invention reduces the display area by centralizing messages transmitted and/or received by each network, and displays these messages to an independent area on a time series basis. The system also enables transmission of messages to the network, to which the relevant message is transmitted, by identifying the message centralized for display. As a result, manipulation efficiency of the information exchange system is improved.

Abstract: A server and plural terminal devices form a network. Messages are transferred among the terminal devices via a plurality of virtual communication spaces formed on the network. The transmitted and received messages are displayed on a display device of each terminal device together with the message sender identifying information. The identifiers of members utilizing the virtual communication spaces and character-train information corresponding to the respective identifiers are stored in a display name management table. When an identifier and a message are sent from a terminal device, the server converts the identifier into a character train by means of the display name management table and sends the character train to the terminal devices.
