Abstract
A processing system includes a transmitter module, a receiver module, and a determination module. The transmitter module is configured to drive a first contact, a second contact, and a third contact of a first transmitter electrode, wherein the first contact is disposed between the second contact and the third contact. This produces a first voltage gradient between the first contact and the second contact, and produces a second voltage gradient between the first contact and the third contact. The receiver module receives, with a first receiver electrode, a first resulting signal including effects of the first voltage gradient, and to receive, with a second receiver electrode, a second resulting signal comprising effects of the second voltage gradient. The determination module determines positional information for an input object located within a sensing region based on the first resulting signal and the second resulting signal.
