1. A method for recognizing a push gesture made on a touch sensing element of a pointing device providing X and Y pointing information to a host, including the steps of:

  • detecting a presence of an object on said touch sensing element at a pressure greater than a threshold;

    initiating a push gesture signal to the host when said pressure becomes greater than said threshold;

    detecting when said pressure of said object falls below a second threshold; and

    maintaining said push gesture signal and repeatedly sending X and Y pointing information to said host until said pressure drops below said second threshold.
