INPUT DETECTION METHOD, INPUT DETECTION DEVICE, INPUT DETECTION PROGRAM AND MEDIA STORING THE SAME
First Claim
1. 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;
(d) handling an area on a second electrode line, which is to be scanned after the first electrode line, as a separation area, wherein the location of the area on the second electrode line corresponds to the location of the separation area detected on the first 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.

Abstract
The invention provides an input detection method, wherein when multiple touch points are input a touch sensor 30 detects touch points 41, 42 individually. The detection method includes: scanning a first electrode line, and if a plurality of touch areas 43, 45 sandwiching a non-touch area 44 are detected, labeling the plurality of touch areas 43, 45 sequentially; determining the location of the non-touch area as a separation area in the case where the non-touch area between the labels is within a predetermined spacing; when a second electrode line next to the first electrode line where a separation area is detected is scanned, handling the area on the second electrode line corresponding to the separation area on the first electrode line as a separation area; and practicing the above steps for every electrode line and detecting the labels.
