Abstract
A sensor for a touch screen operates to detect a touch and any associated movement thereof on the screen and determine a required control function for a device on which the touch screen is mounted. The sensor includes integrated control logic. The sensor operates to identify the existence of a feature associated with the touch and movement on the screen. The feature is processed by the logic to determine the location of the touch and any associated movement thereof on the touch screen. The feature location and any associated movement are converted by the logic into an output from which the control function can be derived by the device.
Claims28
An apparatus, comprising:
- a sensor for a touch screen configured to detect a touch and any associated movement thereof on the touch screen and to determine a required control function for a device associated with the touch screen,
- wherein the sensor includes integrated control logic that is configured to identify the existence of a feature associated with touch and movement on the screen;
- and
- wherein the integrated control logic is further configured to process the feature to determine the location of the touch and any associated movement thereof on the touch screen and convert the feature location and any associated movement into an output from which the control function can be derived by the device.
An image processing circuit, comprising:
- a first sensor;
- and
- a second sensor;
- wherein each of the first and second sensors comprises:
- a sensor configured to detect a touch and any associated movement thereof and to determine a required control function,
- wherein the sensor includes integrated control logic that is configured to identify the existence of a feature associated with touch and movement;
- and
- wherein the integrated control logic is configured to process the feature to determine the location of the touch and any associated movement thereof and convert the feature location and any associated movement into an output from which the control function can be derived;
- and
- wherein the integrated control logic of the first sensor is able to output its identified feature to the second sensor, and
- wherein the integrated control logic of the second sensor is able to process both the identified feature of the first sensor and the identified feature of the second sensor to determine the location of the touch and any associated movement thereof and convert the feature location and any associated movement into an output from which the control function can be derived.
A method for detecting a touch and any associated movement thereof on a touch screen, by means of at least one sensor including integrated control logic therein, to thereby determine a required control function for a device on which the touch screen is mounted, wherein the method comprises:
- identifying the existence of a feature associated with the touch and any associated movement on the screen;
- and
- processing the feature to determine the location of the touch and any associated movement thereof on the touch screen and convert the feature location and any associated movement into an output from which the control function can be derived by the device.
