Abstract
A method for calibrating a touch sensor includes: at a calibration system during a calibration routine, applying a probe, at a target selection force, to a sequence of locations on a touch sensor surface of a touch sensor; at the touch sensor, capturing a sequence of touch images representing magnitudes of forces detected on the touch sensor surface during the calibration routine; fusing the sequence of touch images into a response map representing magnitudes of forces detected on the touch sensor surface by the touch sensor responsive to application of the target selection force on the touch sensor surface by the probe during the calibration routine; generating a force compensation map defining threshold forces for detecting selections at the target selection force on the touch sensor surface based on the response map.
