Abstract
A technique for operating a capacitive sensor array. The technique includes logically grouping capacitance sensors of an array of capacitance sensors into sensor groups. The sensor groups each include at least two capacitance sensors of the array of capacitance sensors. Values indicative of a capacitance for each of the sensor groups are measured. The measured values are then analyzed to determine a location of a user interaction with the array of capacitance sensors.
