Abstract: A device is provided. The device comprises a conductive element comprising one or more grooves, a capacitive field measurement element coupled to the conductive element, and a controller coupled to the capacitive field measurement element. The grooves comprise material with conductivity lower than the conductivity of the conductive element. The capacitive field measurement element is configured to measure change in the capacitive field in proximity of the grooves caused by physical interaction or proximity between the grooves and an external object, and provide the measurement to the controller. The controller is configured to trigger at least one function assigned to the one or more grooves when a change in the capacitive field in proximity of the one or more grooves is measured. Methods of operation and manufacture are also presented.

Abstract: A method may comprise obtaining image data of a plurality of digital image frames captured of an assumed eye having an iris and a pupil while illuminating the assumed eye from different directions; obtaining comparison data dependent on similarities in parts of image data of at least two of the plurality of digital image frames corresponding to an area of interest of the assumed eye; and automatically determining, on the basis of the comparison data, presence of a verification feature in the assumed eye indicating a real eye.

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.
