Sensor array touchscreen recognizing finger flick gesture and other touch gestures
DC CAFCFirst Claim
1. 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.

Abstract
Touchscreen user interfaces for controlling software applications, computers, devices, machinery, and process environments with at least finger flick touch gestures. Such user interfaces can be manipulated by users and provide a wide range of uses with computer applications, assistance to the disabled, and control of electronic devices, machines, and processes. Enhancements can include velocity and pressure sensing capabilities. The touchscreen can be realized with a transparent touch sensor array positioned over a visual display. Dynamically assigned labels can be provided by the visual display. Gestures other than finger flicks can be recognized. Multitouch capabilities can be included that are responsive to additional contact, for example by other parts of a user hand. Displayed visual content, including visual content selection, motion, and sizing, can be controlled by finger flicks and other touch gestures. Finger movement trajectories can be tracked, and pluralities of control parameters can be associated with each gesture.
