Guide display control apparatus, guide display control method, and route guiding system

A guide display control apparatus comprising:

• detection signal obtaining circuitry to obtain a detection signal including identification information of a facility user who has entered one of monitoring areas in each of which a corresponding one of approach detectors is installed, from one of the approach detectors each of which is to detect entry of the facility user into a corresponding one of the monitoring areas, the approach detectors having respective device numbers different from each other, the detection signal further including one of the device numbers, the one of the approach detectors which has detected entry of the facility user having the one of the device numbers;
• schedule obtaining circuitry to obtain a schedule indicating a visit order to destinations, the schedule being associated with the identification information included in the detection signal obtained by the detection signal obtaining circuitry;
• next destination specifying circuitry to specify a next destination in the visit order among at least one of the destinations that has not been visited by the facility user yet on a basis of the schedule obtained by the schedule obtaining circuitry, progress status of the schedule stored in an internal memory, and the one of the device numbers which is included in the detection signal obtained by the detection signal obtaining circuitry, and to update the progress status in such a way as to indicate that a destination before the specified destination in the visit order has been visited;
• and
• display data generating circuitry to search for a route from the one of the monitoring areas to the next destination specified by the next destination specifying circuitry and generate display data for displaying a guide diagram of the route, the one of the monitoring areas being a detection target of the one of the approach detectors which has the one of the device numbers which is included in the detection signal obtained by the detection signal obtaining circuitry.
