SENSOR ARRAY TOUCHSCREEN RECOGNIZING TOUCH GESTURES
First Claim
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;
a plurality of sensor spatial locations having 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 postures derived from pressure profiles.

Abstract
Touchscreen user interfaces for controlling software applications, computers, devices, machinery, and process environments with 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. 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.

14. 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 touch pad, 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; a plurality of control parameters associated with a plurality of postures and a plurality of touch gestures, each of the plurality of touch gestures comprised of sequential dynamics among a set of postures from the plurality of postures, each of the plurality of touch gestures associated with a measured change to at least one of the associated sensor measurement values, wherein each of the plurality of postures is associated with a corresponding pattern of contact of the one or more fingers on the transparent touch pad sensed by the plurality of transparent sensors, wherein at least one of the plurality of control parameters is derived from recognizing one of the plurality of touch gestures from the corresponding sequential dynamics among postures from the plurality of postures, and a plurality of control signals associated with the plurality of control parameters; and
wherein the set of postures and gestures correspond to interactions with displayed visual content of an application operating on the apparatus. - View Dependent Claims (15, 16, 17)
