Patent ID: 8717303

Claim:
A method of controlling visual output produced by an application, the method comprising: sensing a contiguous region of contact from at least a portion of a human hand on a surface of a transparent touchpad, the transparent touchpad comprising a sensor array comprising a plurality of sensors, each sensor having a unique spatial location and an associated unique address, the transparent touch pad for positioning over a visual display, the sensing comprising generation of sensor measurement values associated with each of the plurality of sensors; identifying a plurality of sensor spatial locations having associated sensor measurement values responsive to the sensed contiguous region of contact; measuring a change in at least one of the associated sensor measurement values; interpreting the measured change in sensor measurement values as a touch gesture; deriving a value of at least one control parameter for the contiguous region of contact responsive to the measured change in sensor measurement values by performing a calculation on the associated sensor measurement values; and assigning at least one derived control parameter to a specific control signal, wherein the at least one control parameter is associated with the touch gesture; wherein the touch gesture comprises a finger flick touch gesture recognized from sequential dynamics among postures derived from pressure profiles.
