1. A cursor simulator installed in a main system, the main system comprising a display device having a predetermined display frame for displaying a cursor, the main system is connected to an optical reading device having a predetermined view scope, wherein when the optical reading device receives a plurality of optical signals, the optical reading device transmits the optical signals to the main system, and the main system transmits the optical signals to the cursor simulator, the cursor simulator comprising:

  • a receiving module for receiving the optical signals;

    a position corresponding module for corresponding the view scope of the optical reading device to the display frame of the display device so that each position in the view scope corresponds to a position on the display frame;

    a display module for detecting the position on the display frame corresponding to the position of the optical signal in the view scope, and displaying the optical signal on a simulation display frame, wherein the simulation display frame comprises a plurality of optical signal display positions, and each optical signal display position corresponds to a specific position on the display frame;

    a specific area display module for marking a specific area on the display frame;

    a limb image color parameter acquiring module for reading the color parameter of each optical signal display position in an area on the simulation display frame corresponding to the specific area of the display frame so as to obtain a limb image color parameter according to the variation of the color parameter of the optical signal display position; and

    a limb image forming module for reading the color parameter of each optical signal display position on the simulation display frame, wherein when the color parameter is approximately equal to the limb image color parameter, the limb image forming module records the optical signal display position, and then form a simulated limb image according to all of the recorded optical signal display positions.
