1. A method for controlling the operation of a computer system using a pointing device, the computer system including a keyboard having a plurality of keys, a display for displaying visual information, a processor to generate and manage the visual information, and a storage medium, the pointing device being coupled to the computer system and including means for generating movement information to effect the movement of a cursor to any of a plurality of cursor positions at different coordinates on the display, the method comprising the steps of:

  • (a) storing in the storage medium a representation of the pointing device movement information indicative of a cursor trajectory caused by movement of the pointing device;

    (b) calculating a cursor-heading, time variation-profile from the stored representation of the pointing device movement information; and

    (c) comparing the cursor-heading, time variation-profile with a pre-defined characteristic cursor-heading, time variation-profile and controlling said computer system to execute a predetermined command when the cursor-heading, time variation-profile substantially matches the pre-defined characteristic cursor-heading, time variation-profile.
