• identifier, if the detector detects that the user has left the current entrance/exit point, for identifying the next entrance/exit point to the current entrance/exit point among the entrance/exit points within the route;
• acquirer for acquiring map showing the route from the current entrance/exit point to the next entrance/exit point identified by the identifying means through the communication between the communication apparatus provided at the exit of the current entrance/exit point and the computer;
• and
• display controller for controlling a display screen of the computer so as to display the map showing the route from the current entrance/exit point to the next entrance/exit point acquired by the acquirer.
