Abstract
A device includes sensor substantially coplanar with one another in a sensor plane, each sensor generating a sense value that varies according to a physical distance between the sensor and an object without physically contacting the object. The device also includes control circuits configured to generate a first position value, a second position value, and a third value using the sense values. The first position value and the second position values identify a two-dimensional position of the object in the sensor plane and the third value varies in response to movement of the object in a Z-direction substantially perpendicular to the sensor plane. The control circuits include a programmable integrated circuit including an analog portion and a digital portion.
