1. A hybrid touch and force sensing apparatus, comprising:

  • a touch panel having one or more sensors adapted to determine coordinates of a received touch;

    one or more force-based touch sensors coupled to the touch panel; and

    a processor;

    whereinthe touch panel outputs the coordinates of the received touch to the processor and the one or more force-based touch sensor outputs sensors output a z-force coordinate to the processor;

    the processor divides the touch panel into a plurality of zones, determines which of the plurality of zones received the touch, retrieves a predetermined compensation factor for a determined zone, and applies the predetermined compensation factor to the z-force coordinate; and

    the predetermined compensation factor is based on a distance between the coordinates of the received touch and the one or more force-based touch sensors.
