Patent ID: 8743061

Claim:
A touch sensing method for a touch sensor board including a plurality of first and second sensor lines, the first sensor lines and the second sensor lines being aligned in two different directions, respectively, said touch sensing method comprising: a) scanning the first and second sensor lines to generate scan results; b) generating first and second indications based on the scan results of step a), wherein the first indication carries information of at least one group of the first sensor lines and an amount of the first sensor lines of the group, which are adjacent to one another and have detected a user's touch on the touch sensor board, and the second indication carries information of at least one group of the second sensor lines and an amount of the second sensor lines of the group, which are adjacent to one another and have detected the user's touch on the touch sensor board; and c) generating a status signal that corresponds to a predetermined finger gesture, which at least based on a comparison result determined by comparing the amount of the first sensor lines adjacent to one another detected simultaneously as indicated by the first indication with the amount of the second sensor lines adjacent to one another detected simultaneously as indicated by the second indication.
