Abstract
A portable device is provided. The device comprises a controller, a touch sensing element, a capacitance measurement element integrated in the touch sensing element and coupled to the controller, and at least one mechanical pressing region coupled to the capacitance measurement element. The capacitance measurement element is configured to measure change in capacitance of at least one mechanical pressing region caused by proximity or physical interaction between the at least one mechanical pressing region and an external object. A system and method are also presented.
