1. A capacitive sensing device comprising:
a substantially transparent substrate; and
a first set of patterned conductive traces formed above said substantially transparent substrate, said first set of conductive traces comprising a plurality of layers, at least one of said plurality of layers comprising a material that is substantially non-reflective and optically absorbent, and at least another of said plurality of layers being a substantially opaque material, each of said first set of patterned conductive traces having a width such that said capacitive sensing device does not have to be arranged with respect to an underlying image in order to avoid deleterious obstruction of said underlying image by said first set of patterned conductive traces, said underlying image is separate from said capacitive sensing device, wherein said capacitive sensing device is separate from active components used to comprise an information display device.
