Abstract
A method for determining the number of fingers on a sensing device, which has a plurality of scanlines, includes the steps of: identifying the scanlines that generate a detecting signal, which has a value greater than a threshold value; finding adjacent ones of the scanlines; forming at least one group from the adjacent ones of the scanlines thus found; and counting the number of the scanlines in the at least one group thus formed in order to determine the number of fingers on the sensing device.
