Claim 16:
17. The apparatus of claim 14, further comprising:
a third pair of electrodes orthogonal to the first pair of electrodes, comprising a sixth fixed electrode and a seventh fixed electrode separated from the sixth fixed electrode by a third distance; and
a fourth pair of electrodes orthogonal to the second pair of electrodes and adjacent to the third pair of electrodes, comprising an eighth electrode and a ninth electrode separated from the eighth electrode by a fourth distance,
wherein the capacitance sensing circuit is further coupled to the third and fourth pairs of electrodes and further configured to determine capacitances of a fifth capacitor and a sixth capacitor using the third pair of electrodes and the capacitances of a seventh capacitor and an eighth capacitor using the fourth pair of electrodes.
