Abstract
A method for detecting force applied to a capacitive sensor array and compensating for coordinate inaccuracy due to force includes receiving a plurality of capacitance measurements from the capacitive sensor array, where the plurality of capacitance measurements includes a first capacitance measurement and a second capacitance measurement, and detecting pressure on the capacitive sensor array based on a comparison between the first capacitance measurement and the second capacitance measurement.
