Claim 4:
5. A remote operation system in which a plurality of users who are present in locations away from each other remotely operate a plurality of respective remote operation mobile bodies that are located in one place by operating respective remote operation terminals that the plurality of users have, the remove operation system comprising:
the plurality of remote operation mobile bodies; and
the plurality of remote operation terminals, wherein
each of the remote operation mobile bodies comprises:
a control command reception unit configured to receive a control command from the corresponding remote operation terminal;
an operation control unit configured to control the operation of the own remote operation mobile body based on the control command;
an imaging unit;
a captured image information acquisition unit configured to acquire captured image information from the imaging unit;
a captured image information transmission unit configured to transmit the captured image information to the corresponding remote operation terminal;
a mobile-body-side microphone;
a mobile-body-side sound pressure information acquisition unit configured to acquire sound pressure information from the mobile-body-side microphone;
a mobile-body-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the mobile-body-side sound pressure information acquisition unit to the corresponding remote operation terminal;
a mobile-body-side sound pressure information reception unit configured to receive sound pressure information from the corresponding remote operation terminal; and
a mobile-body-side output unit configured to output the sound pressure information received by the mobile-body-side sound pressure information reception unit, and

each of the remote operation terminals comprises:
a control command input unit configured to accept an operation of inputting the control command;
a control command transmission unit configured to transmit the control command to the corresponding remote operation mobile body;
a captured image information reception unit configured to receive the captured image information from the corresponding remote operation mobile body;
a captured image information display unit configured to display the captured image information;
a terminal-side microphone;
a terminal-side sound pressure information acquisition unit configured to acquire sound pressure information from the terminal-side microphone;
a first-terminal-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the terminal-side sound pressure information acquisition unit to the corresponding remote operation mobile body;
a first-terminal-side sound pressure information reception unit configured to receive sound pressure information from the corresponding remote operation mobile body;
a second-terminal-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the terminal-side sound pressure information acquisition unit to another remote operation terminal;
a second-terminal-side sound pressure information reception unit configured to receive sound pressure information from another remote operation terminal;
a terminal-side output unit configured to output the sound pressure information received by the first-terminal-side sound pressure information reception unit or the second-terminal-side sound pressure information reception unit; and
a conversation control unit configured to execute an inter-mobile-body conversation mode that establishes conversation with another user using the first-terminal-side sound pressure information transmission unit and the first-terminal-side sound pressure information reception unit and an inter-terminal conversation mode that establishes conversation with another user using the second-terminal-side sound pressure information transmission unit and the second-terminal-side sound pressure information reception unit in such a way that they can be switched, wherein

each of the remote operation mobile bodies comprises:
a current location information acquisition unit configured to acquire current location information of the own remote operation mobile body; and
a current location information transmission unit configured to transmit the current location information to the corresponding remote operation terminal,

each of the remote operation terminals comprises:
an own body current location information reception unit configured to receive the current location information from the corresponding remote operation mobile body;
an own body current location information transmission unit configured to transmit the current location information received by the own body current location information reception unit to another remote operation terminal; and
an another body current location information reception unit configured to receive current location information of another remote operation mobile body from the other remote operation terminal, and

the terminal-side output unit calculates the distance between remote operation mobile bodies that correspond to the respective users talking to each other based on the current location information of the own remote operation mobile body received by the own body current location information reception unit and the current location information of the other remote operation mobile body received by the other body current location information reception unit while the conversation control unit is executing the inter-terminal conversation mode, and decreases an amplification rate of the sound pressure information when the sound pressure information is output as the calculated distance becomes longer.
