ABSTRACT:
One embodiment in accordance with the invention includes a capacitive sensor apparatus that includes a first sensing element having substantially constant width along its length and configured to have varying capacitive coupling to an object proximate to a capacitive sensing reference surface, along a first axis of the capacitive sensing reference surface. The length of the first sensing element is oriented along the first axis. The capacitive sensor apparatus can include a second sensing element having substantially constant width along its length and configured to have varying capacitive coupling to the object proximate to the capacitive sensing reference surface along the first axis. The length of the second sensing element is oriented along the first axis. The first and second sensing elements are conductive, and are configured to provide information corresponding to a spatial location of the object relative to the first axis of the capacitive sensing reference surface.
