1. An image-based object tracking system, comprising:

  • a controller, the controller comprising two or more color clusters;

    a camera, configured to capture real-time images of the controller; and

    a processing unit, for receiving the real-time images of the controller and executing an object tracking algorithm so as to provide real-time display of processed image contents from the captured images of the controller on a monitor screen;

    wherein the processing unit configured for;

    performing color learning on the controller using a learning box and a color learning algorithm;

    upon determining color learning being successful, storing the color learning results of the controller, and starting object tracking of the controller using the color learning results; and

    upon determining that color relearning of the controller is required, repeating the performing color learning step, otherwise showing a learning error message;

    capturing images of the controller;

    separating and splitting the controller and the background by color differences using the color learning results;

    providing color labeling and color filtering to the controller and the background; and

    performing an object pairing procedure on the controller, and upon determining that the object pairing of the controller is successful, performing output of the object features of the controller;

    wherein the controller is configured to be directly interacting with the displayed processed image content on the monitor screen.
