Claim 7:
8. A sensor system comprising:
a sensing area disposed along a surface of the sensor system;
a first sensing region disposed within the sensing area comprising a first sensor configured to detect a first applied force applied to the surface of the sensing area;
a second sensing region disposed within the sensing area comprising a second sensor configured to detect a second applied force applied to the surface of the sensing area; and
a processor that, when executing computer readable and executable instructions of the sensor system, causes the sensor system to:
detect a force applied to the sensing area of the sensor system;
calculate the first force and the second force using stored calibration curves including a relationship between peak generated electrical signals and a corresponding force measurement;
determine 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;
determine that the second sensing region is an incorrect sensing region when a second relative magnitude is not within the relative threshold of the total applied force;
determine an activation area of the incorrect sensing region;
determine a force distribution of the incorrect sensing region; and
calculate a corrected corresponding force measurement of the incorrect sensing region based on the activation area and force distribution of the incorrect sensing region.
