Abstract
A method for performing capacitive force sensing involves acquiring a plurality of changes of capacitance at a plurality of sensor electrodes, determining an input object location, obtaining a mixed signal representing the plurality of changes of capacitance at the input object location, wherein the mixed signal comprises a touch signal portion and a bending signal portion, identifying at least one inflection point using the mixed signal, using the at least one inflection point, identifying a touch signal region of the mixed signal, performing curve fitting to complete the bending signal portion in the touch signal region of the mixed signal to obtain a completed bending signal, and determining an applied force based on the completed bending signal.
