    Abstract: An at-desk notice system includes plural clients, and a server. Each of clients includes a notice display unit for displaying at-desk notice information on a monitoring-target user, and a state notice unit for notifying the server of a change in state information on a user of the client. The server includes a judgment unit for determining whether the state information, the change of which is notified by the clients, has changed to an at-desk state and whether the change-notified user is monitored by other user, and a notice unit for issuing, to the client of the other user, a notice that the monitoring-target user becomes the at-desk state.
