Abstract
A touch location on a capacitive touchscreen system is identified by receiving signals in response to a touch from electronic channels connected to one electrode or to a group of semi-adjacent electrodes provided on a substrate. Adjacent ones of the electrodes have substantially triangular shapes that alternate between a first and second orientation to form an interleaved arrangement such that the touch generates a signal cluster comprising the signals generated from a series of adjacent electronic channels. Weights with at least two different numerical values are applied to the signals from the series of adjacent electronic channels. The at least two different numerical values are based on levels of the signals. A location of the touch on the substrate is determined based on the weighted signals.
