System and method for optimizing the consumption of power while maintaining performance in capacitive sensor arrays. A limited sensing area is used to improve the update rate and sensitivity of a row/column array of capacitive sensors. According to one embodiment, a method is provided for scanning a plurality of capacitive sensors by: detecting a stimulus in the field of capacitive sensors, scanning the field of capacitive sensors to determine the position of the stimulus. Once the position of the stimulus is determined, a subsection of the field comprising window corresponding to the position of the stimulus remains activated while the remaining sensors in the field are deactivated.
