Abstract

A system and method provide for selecting a sensor in an array of capacitive sensors, determining a row intensity for the selected sensor, and determining a column intensity for the selected sensor. The system and method may also provide for compensating the selected sensor for multi-touch signal bias drift, wherein the compensating may include adjusting an intensity of the selected sensor based on the row and column intensity.
