Abstract
Techniques for obtaining force-based data of an input device are provided. The techniques include driving sensor electrodes in transcapacitive mode and in absolute capacitive mode, obtaining profiles for each of the modes, scaling the transcapacitive profile, and subtracting the scaled transcapacitive profile from the profile for absolute capacitive sensing. The result of this subtraction is force-based data that indicates the degree of force with that input object applies to the input device. These techniques may be used with an input device in which a plurality of sensor electrodes are divided into two or more segments. Independent sets of force-based data can be obtained for each segment, which allows for determination of a location associated with each set of force-based data.
