Abstract
A transparent overlay input device includes a transparent non-conductive substrate, a plurality of transparent conductive electrode pairs and a transparent non-conductive cover. The plurality of transparent conductive electrode pairs are formed on the substrate and each form a proximity sensitive region and include a first electrode that receives an input signal and a second electrode that provides an output signal. The first and second electrodes are capacitively coupled and the capacitance of the electrode pair changes when a conductive member, e.g., a user's finger, is located near the electrode pair. The transparent non-conductive cover is formed on the substrate over the electrode pairs.
