Patent ID: 8553003

Claim:
An input detection method for separately detecting multiple touches input to a touch sensor, wherein the touch sensor is provided with a plurality of electrodes arranged in a matrix, and the touch sensor detects the multiple touches by sequentially scanning electrode lines where the electrodes are arranged, comprising: (a) scanning a first electrode line to detect whether a plurality of contact areas sandwiching a non-touch area exist in the scanning direction; (b) labeling the plurality of contact areas in sequence; (c) determining the non-contact area between the labels as a separation area in the case where the non-touch area between the labels is within a predetermined spacing of a distance of one coordinate or two coordinates in a predetermined coordinate system; (d) handling an area on a second electrode line, which is to be scanned after the first electrode line, as a separation area comprising of a non-contact area, wherein the location of the area on the second electrode line directly corresponds to the location of the separation area detected on the first electrode line prior to scanning the second electrode line; and (e) performing steps (a)˜(d) in sequence for each electrode line, and finding the central locations of the touches according to the labels.
