Abstract
A touch sensor employing capacitive sensing technology in which a series of conductive pads enabling the detection of levels of capacitance imparted to each of the conductive pads as a result of the close proximity of a tip of a digit of a user, in which adjacent pairs of the conductive pads form slider controls, in which one of the conductive pads is a corner-type conductive pad at which two adjacent slider controls formed by the corner-type conductive pad and each of two adjacent conductive pads forms a corner in the series of slider controls, and in which the series of slider controls perhaps forms a rectangular ring shape loop of slider controls in which there are four of the corner-type conductive pads at which four different pairs of slider controls meet at right angles.
