Abstract
One embodiment in accordance with the present invention includes a capacitive sensing device. The capacitive sensing device comprises a substantially transparent substrate and a set of patterned conductive traces formed above the substantially transparent substrate. Each of the set of patterned conductive traces has a width such that the capacitive sensing device does not have to be arranged with respect to an underlying image in order to avoid deleterious obstruction of the underlying image by the set of patterned conductive traces. The underlying image is separate from the capacitive sensing device. The capacitive sensing device is separate from active components used to comprise an information display device.
