Detecting multiple simultaneous touches on a touch-sensor device
First Claim
1. An apparatus, comprising:
- a first set of sensor elements disposed in a first axis in a plane of a touch-sensor device;
a second set of sensor elements and a third set of sensor elements disposed in a second axis in the plane, wherein the second set of sensor elements is disposed in a first section of the touch-sensor device and the third set of sensor elements is disposed in a second section of the touch-sensor device that is adjacent to the first section, wherein the first set, second set, and third set of sensor elements are configured to be separately scanned to detect a presence of one or more conductive objects on the touch-sensor device; and
a processing device coupled to the first set, second set, and third set of sensor elements, wherein the processing device is configured to detect the presence of the one or more conductive objects on the touch-sensor device, and wherein the processing device is configured to resolve a plurality of locations of a plurality of substantially simultaneous touches on the touch-sensor device without an all-points-addressable array of sensor elements in the touch-sensor device.

Abstract
An apparatus and a method for resolving locations of two or more substantially simultaneous touches on a split touch-sensor device. The method may include detecting multiple substantially simultaneous touches on a touch-sensor device having multiple sections in at least one dimension of the touch-sensor device, and resolving locations of the multiple substantially simultaneous touches on the touch-sensor device without an all-points-addressable (APA) array. Resolving the multiple locations includes resolving a first location in a first section of the multiple sections and resolving a second location in a second section that is adjacent to the first section of the touch-sensor device. The apparatus may include a first set of sensor elements disposed in a first axis in a plane of a touch-sensor device, and a second set of sensor elements and a third set of sensor elements disposed in a second axis in the plane.

11. A method, comprising:
-
detecting a plurality of substantially simultaneous touches on a touch-sensor device having a plurality of sections in at least one axis of the touch-sensor device; and resolving a plurality of locations of the plurality of substantially simultaneous touches on the touch-sensor device when the plurality of substantially simultaneous touches are detected on the touch-sensor device without an all-points-addressable array (APA) array of sensor elements in the touch-sensor device, wherein said resolving comprises; resolving a first location of the plurality of locations in a first section of the plurality of sections; and resolving a second location of the plurality of locations in a second section of the plurality of sections that is adjacent to the first section; wherein resolving each of the first and second locations comprises; scanning a first set of sensor elements disposed in a first axis of the touch-sensor device; scanning a second set of sensor elements disposed in a second axis of the touch-sensor device, wherein the second set of sensor elements are disposed in the first section; and scanning a third set of sensor elements disposed in the second axis of the touch-sensor device, wherein the third set of sensor elements are disposed in the second section. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
