1. An apparatus comprising:

  • a touch screen having a contiguous region sensing contact from at least a portion of a human hand on a surface of the touch screen, the touch screen comprising a display and a sensor array comprising a plurality of sensors in physical contact with the display, each of the plurality of sensors configured with a unique spatial location and an associated unique address, each of the plurality of sensors configured to generate sensor measurement values, wherein a plurality of sensor spatial locations are configured to provide associated sensor measurement values responsive to the contiguous region of contact;

    a value of at least one control parameter for the contiguous region of contact responsive to a measured change in at least one of the associated sensor measurement values, the value obtained by performing a calculation on the associated sensor measurement values and interpreting the results as signifying a touch gesture, wherein the at least one control parameter is associated with the touch gesture; and

    at least one derived control parameter assigned to a specific control signal;

    wherein the touch gesture is recognized from sequential dynamics among hand contact patterns from a first posture associated with a first portion of a user hand at a first location on the touch screen to a second posture associated with a second portion of the user hand at a second location on the touch screen, wherein the first portion of the user hand and the second portion of the user hand are different.
