1. A position detecting system comprising:

  • an information transmission device, comprising a plurality of transmitters, for transmitting predetermined information;

    a mobile terminal for receiving the predetermined information; and

    a control device capable of communicating with the mobile terminal, the mobile terminal including;

    a display for displaying a first image and a second image, wherein the second image is part of the first image;

    first receiver circuitry for receiving the predetermined information transmitted from the information transmission device;

    an image processing unit for changing the first image in accordance with the predetermined information received by the first receiver circuitry;

    a pointing device for accepting an input by a user, whereinthe input by the user comprises a selection of a predefined course comprising course data, wherein the course data includes predetermined coordinates of a series of predetermined destination positions of the mobile terminal associated with the selected course; and

    transmitter circuitry for transmitting, to the control device, current positional information corresponding to the predetermined information received by the first receiver circuitry and operation information indicating the input entered by the user through the pointing device,the control device arranged separately from the mobile terminal and the information transmission device and including;

    second receiver circuitry for receiving the current positional information and the operation information transmitted from the mobile terminal;

    provider circuitry for providing feedback information to a user of the mobile terminal, whereinthe image processing unit changes the second image in accordance with the current positional information, andthe provider circuitry provides the feedback information based on the operation information and the received current positional information transmitted by the mobile terminal, whereinthe image processing unit changes a display form of the second image between a first display form indicating the second image is selectable by the user and a second display form indicating the second image is not selectable by the user when the current positional information indicates a predetermined destination position of the series of predetermined destination positions associated with the selected course, and whereinthe display form indicates that the second image is selectable when the current positional information indicates the predetermined destination position.
