Claim 0:
1. A method comprising:
detecting a force applied to a sensing area of a sensor system based on a first force applied to a first sensing region of the sensing area determined by a first sensor and a second force applied to a second sensing region of the sensing area determined by a second sensor, the first force and the second force calculated using stored calibration curves including a relationship between peak generated electrical signals and a corresponding force measurement;
determining that the first sensing region is a correct sensing region when a first relative magnitude of the first sensing region is within a relative threshold of a total applied force, the total applied force being a sum of at least the first force applied to the first sensing region and the second force applied to the second sensing region;
determining that the second sensing region is an incorrect sensing region when a second relative magnitude of the second sensing region is not within the relative threshold of the total applied force;
determining an activation area of the incorrect sensing region;
determining a force distribution of the incorrect sensing region; and
calculating a corrected corresponding force measurement of the incorrect sensing region based on the activation area and force distribution of the incorrect sensing region.
