Abstract:
1. An apparatus comprising: distinct capacitive sensor electrodes irregularly configured across a sensing area, wherein each capacitive sensor electrode is an island associated with a unique combination of two positional components within the sensing area; and a plurality of conductive traces each of which is operatively connected to one of the distinct capacitive sensor electrodes and wherein at least some of the conductive traces extend over the sensing area; wherein the capacitive sensor electrodes comprise perimeters comprising an upper portion, a lower portion, a right portion and a left portion and wherein the upper portion is an inversion of the lower portion and the left portion is an inversion of the right portion such that when the capacitive sensor electrodes are arranged as an array there is: an upper fixed gap between the upper portion and a lower portion of an adjacent capacitive sensor electrode; a lower fixed gap between the lower portion and an upper portion of another adjacent capacitive sensor electrode; a right fixed gap between the right portion and a left portion of a further adjacent capacitive sensor electrode; and a left fixed gap between the left portion and a right portion of another adjacent capacitive sensor electrode.
