Abstract: An input device includes an insulation substrate, a switch element, and a detection portion. The switch element includes a fixed electrode portion that is provided on the substrate, and a movable electrode portion that is provided on a main surface side of the substrate, at least part of the movable electrode portion being elastically displaceable toward a direction approaching and leaving the fixed electrode portion. The movable electrode portion is displaceable toward a direction approaching the fixed electrode portion due to pressure from an object to be detected that is an electric conductor. The detection portion is capable of detecting a capacitance change caused by the object to be detected approaching and leaving the movable electrode portion and a capacitance change between the movable electrode portion and the fixed electrode portion produced by displacement of the movable electrode portion due to pressing.

Abstract: A touch-sensing apparatus may include a first controller configured to measure a first set of capacitance values from a first area of a touch-sensing surface and a second controller coupled with the first controller, where the second controller is configured to receive the first set of capacitance values from the first controller, and calculate a first position of a contact at the touch-sensing surface based on the first set of capacitance values and a second set of capacitance values measured from a second area of the touch-sensing surface adjacent to the first area of the touch-sensing surface.

Abstract: An apparatus for determining at least one centroid location for a contact at a touch-sensing surface may include a first slave controller coupled to a first capacitive touch panel comprising a first plurality of sensor elements, where the first slave controller is configured to measure a first set of capacitance values for a plurality of intersections of the first plurality of sensor elements, and a master controller coupled with the first slave controller, where the master controller is configured to receive the first set of capacitance values and calculate a first centroid position of a contact based on the first set of capacitance values and a second set of capacitance values.
