Abstract
This application is directed to detecting touch events on a touch sensing surface coupled to a capacitive sense array and one or more force sensors. The capacitive sense array includes a plurality of sense electrodes configured to provide a plurality of capacitive sense signals. The force sensors are configured to provide one or more force signals. In accordance with the plurality of capacitive sense signals, one or more candidate touches are determined on the touch sensing surface, and used to determine an expected force shape. An actual force shape caused on the touch sensing surface by the candidate touches is determined from the one or more force signals. The actual and expected force shapes are compared to determine magnitudes of force associated with each of the one or more touch candidates, thereby determining whether each of the one or more candidate touches is a valid touch.
