1. A computer-implemented method of automatically calibrating a pointing device respective to a writing surface during normal operation of the writing surface, the method comprising the steps of:

  • (a) displaying data on a display device having a writing surface thereon, the display device being in operative communication with a computing device;

    (b) receiving at least one operational user input on at least one actual location upon the writing surface during usage of the computing device, wherein the user input is indicative of attempting at least one function other than calibration;

    (c) determining a miscalibration vector between the location on the writing surface of the at least one user input and at least one expected location on the writing surface of the at least one user input; and

    (d) recalibrating the writing surface with respect to at least one axis.
