Abstract
A touch sensing method includes: scanning a plurality of first and second sensor lines, aligned in two different directions, of a touch sensor board; generating first and second indications based on the scan result, the first/second indication carrying information of at least one group of the first/second sensor lines that are adjacent to one another on the touch sensor board and that have detected a user's touch on the touch sensor board and of a number of the first/second sensor lines in the group; and generating a status signal that corresponds to a predetermined finger gesture at least based on a comparison result determined by comparing the number of the first sensor lines indicated by the first indication with the number of the second sensor lines indicated by the second indication. An electronic device that implements the touch sensing method is also disclosed.
