Abstract
A capacitive sensor apparatus comprises a first sensing element and a second sensing element. The first sensing element has a length oriented along a first axis of a contactable capacitive sensing reference surface; has a substantially constant width along its length; and is configured to have varying capacitive coupling, along the first axis, to an object proximate to the contactable capacitive sensing reference surface. The second sensing element has a length oriented along the first axis; has substantially constant width along its length; and is configured to have varying capacitive coupling, along the first axis, to the object proximate to the contactable capacitive sensing reference surface. The first sensing 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.
