Abstract
An apparatus of one embodiment includes a sensor having a plurality of electrodes and a controller having a processor and a memory. The memory includes logic operable to configure the electrodes to form a first cluster pattern having a plurality of first clusters of two or more electrodes, apply voltage to each first cluster, and determine a plurality of first values associated with a capacitance of a first cluster. The logic is further operable to configure the electrodes to form a second cluster pattern having a plurality of second clusters of two or more electrodes, apply voltage to each second cluster, and determine a plurality of second values associated with a capacitance of a second cluster. At least one second cluster is interleaved with an adjacent second cluster. The logic is further operable to determine a position of an object based at least on the second values.
