Abstract: The present disclosure relates to a man-machine interface, including a steering wheel rotatably supported about a steering wheel axis and an input device attached to the steering wheel, wherein the input device includes a fingerprint sensor with an acquisition surface for acquiring a fingerprint of a finger of an operator and additionally at least one touch-sensitive and/or operation-sensitive input surface, which is disposed outside the acquisition surface and preferably spaced from the acquisition surface, with an associated detection device, and an evaluation unit connected in an electrically conductive manner with the detection device and the fingerprint sensor, wherein the evaluation unit is configured to verify the data acquired by the fingerprint sensor with a signal of the detection device and, if necessary, to discard them.

Abstract: The present disclosure relates to a sensor device for arrangement in a motor vehicle, including: a transmitting unit for emitting an optical signal into a space region of a passenger compartment of the motor vehicle; a receiving unit for sensing the optical signal; an evaluation unit for assigning a switching function and/or controlling function to the reflected optical signal; a cover which is transmissive with respect to the optical signal and disposed between the passenger compartment and the transmitting unit; and further, a capacitive sensor with at least one electrode for generating a measuring capacitance sensing the passenger compartment at least in some portions, and means for detecting a capacitance change of the measuring capacitance; and wherein the evaluation unit is further designed to vary the switching function and/or controlling function and/or to vary the transmitting power of the transmitting unit in accordance with the capacitance change.
