  • Patent number: 6057830
    Abstract: Systems and methods for the detection of motions of a pointed object upon a digitizing surface such as a touchpad is disclosed. The motions will be detected and converted to digital codes representing the absolute coordinates of the pointed objects upon the touchpad. The absolute coordinates will be translated into a stroke signal to interpret a single tap, a double tap, and a tap and drag of the pointed object on the touchpad. Further, multiple sets of absolute coordinates will be translated into a relative motion code that will contain the speed and direction of the pointed object as it is moved across the touchpad. The absolute coordinates will be interpreted by an autocursor controller to determine if the pointed object has transited between a workzone and an edgezone of the touchpad. If the pointed object is in the edgezone, a predefined relative motion code will be transmitted as an autocursor code.
