Touch screen supporting continuous grammar touch gestures
DC CAFCFirst Claim
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.

Abstract
Touch screen user interfaces for controlling software applications, computers, devices, machinery, and process environments with “continuous grammar” touch gestures which begin with finger postures contacting the touch screen with one part of the hand and which conclude with finger postures contacting the touch screen with a different part of the hand without breaking contact with the touch screen. The touch screen can be realized sensor array configured with a visual display arranged to detect touch from one or more fingers. In addition to recognizing simple touch gestures, algorithms comprised by the user interface are additionally arranged to be responsive to pluralities of finger postures executed sequentially without breaking contact with the touch screen. Such user interfaces can be easily used 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.
