<P>PROBLEM TO BE SOLVED: To provide a roll call system capable of allowing a roll called person himself/herself to easily recognize an order of roll call of roll called persons. <P>SOLUTION: The roll call system is a roll call system including a roll calling side device used by a roll call manager who performs a roll call and a plurality of roll-called side devices each of which is used by a roll called person for whom a roll call is performed for sending a state of the roll called person to the roll-calling side device by a sound and an image. The roll called side device transmits a request for roll call to the roll calling side device, and the roll calling side device adds a roll called person to a roll call waiting list which is a list of roll called persons waiting for a roll call in response to the request, and enables a roll call through the roll called side device according to an order of the roll called persons in the roll call waiting list. A PC of the roll called side device obtains the roll call waiting list from the roll calling side device (S141), and distinguishes and displays a roll called person making a request from the roll called side device to which itself belongs from the other roll called person in the roll call waiting list (S143). <P>COPYRIGHT: (C)2012,JPO&INPIT |
