Abstract: An apparatus may include a touch sensor, a touch region of the touch sensor that is free of sense electrodes, a first peripheral region of the touch sensor and a second peripheral region of the touch senor and the touch region is located between the first peripheral region and the second peripheral region, a first sense electrode is located in the first peripheral region, a second sense electrode is located in the second peripheral region.

Abstract: A system and method for increasing the proximity sensing distance of a touch and proximity sensitive touch sensor to thereby enable greater distance of detectability of a user in a proximity sensing mode of a touch sensor by driving a time varying voltage or drive signal onto a user who is also holding a touch sensor with at least one hand, and then sensing the drive signal from the user's fingers or thumb on sense electrodes that are on the touch sensor when the fingers are within a proximity sensing distance of sense electrodes in the touch sensor.

Abstract: A system and method for extending a sensitivity range of a touch and proximity sensor that uses mutual capacitance sensing, the system and method providing projecting electrodes that generate an electric field in a three dimensional volume of space above a touch and proximity sensor to thereby enable the touch and proximity sensor to accurately detect the presence of one or more objects at a greater distance as compared to a touch and proximity sensor that does not have the projecting electrodes to generate a stronger electric field.
