1. An apparatus comprising:
- a transparent touchpad positioned over a visual display, the transparent touchpad configured to sense a contiguous region of contact from at least a portion of a human hand on a surface of the transparent touchpad, the transparent touch pad comprising a sensor array having a plurality of sensors, each sensor having a unique spatial location and an associated unique address, wherein the transparent touch pad is configured to sense the contiguous region of contact by a generation of sensor measurement values associated with each of the plurality of sensors, 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 finger flick touch gesture, wherein the at least one control parameter is associated with the finger flick touch gesture; and
at least one derived control parameter assigned to a specific control signal;
wherein the finger flick touch gesture is recognized from sequential dynamics among postures derived from spatial pressure distribution profiles.

Abstract
Touch screen user interfaces configured to detect a touch gesture for controlling software applications, computers, devices, machinery, and process environments. 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 touch screen can be realized with a transparent touch sensor array positioned over a visual display. The touch screen can be configured to measure a spatial pressure distribution profile from a touch on the touch screen and recognize gestures based on dynamics among spatial pressure distribution profiles. In an example implementation, the gesture recognition may rely solely on dynamics of shape differences between hand contact patterns and omit the use of pressure, as the shape of the spatial pressure distribution profile does not vary much by pressure.

13. An apparatus comprising:
-
a transparent touch sensor array comprising a plurality of transparent sensors positioned over a display associated with the apparatus to form a transparent touchpad, wherein the transparent touch sensor array is configured to sense contact with one or more fingers on a corresponding contiguous region on the transparent touch pad, wherein each transparent sensor of the plurality of transparent sensors has a corresponding spatial location, associated address, and is configured to provide associated sensor measurement values; at least one control parameter associated with a finger flick touch gesture, the finger flick touch gesture recognized from sequential dynamics among postures derived from spatial pressure distribution profiles and associated with a measured change to at least one of the associated sensor measurement values; and at least one control signal associated with the at least one control parameter; and wherein the finger flick touch gesture corresponds to one or more interactions with displayed visual content of an application operating on the apparatus. - View Dependent Claims (14, 15, 16, 17, 18)
