Abstract: A virtual space management unit 60 generates a virtual space information and manages the virtual space information. An icon position acquisition unit 61 acquires icon position information of each of the users U. A transmission-side voice acquisition unit 62 acquires a transmission-side voice information. A distance calculation unit 63 calculates a distance between each of the icons based on a position within the virtual space of the icons corresponding to each of the users U. A correction factor determination unit 64 determines a correction factor of an output information based on the distance between the icons calculated by the distance calculation unit 63. A reception-side voice transmission control unit 65 transmits the acquired transmission-side voice information and the determined correction factor to each of the second user terminals 3.

Abstract: A positional information management unit 80 specifies a position within a virtual space of icons corresponding to respective users based on an icon positional information. When an instruction operation by a user related to an object arranged in the virtual space is performed, the object conversation management unit 62 acquires an object instruction operation information transmitted from each of the user terminals 2. When an instruction operation of the user regarding the object is not performed, a normal conversation management unit 63 executes various processing related to a normal conversation mode. The communication method determination unit 64 determines a method of communication to be provided to the user and a communication method for realizing the communication. An output information generation unit 65 generates an output information to be output at each of the user terminals.
