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 electrodes are configured to provide one or more force signals. In accordance with the capacitive sense signals, one or more candidate touches are detected on the touch sensing surface, and the detected candidate touches include a first candidate touch. When it is determined that force associated with the one or more force signals is associated with a grip on an edge area of the touch sensing surface, the first candidate touch is associated with the grip on the edge area of the touch sensing surface, and is designated as an invalid touch.
