A method and device for compressed transfer of signals of an operating element, to a display unit in a vehicle is disclosed. The method includes transmission of an optical signal to a surface of the operating element, receiving of an optical signal reflected by a finger of a user on the surface of the operating element in a predetermined scanning cycle, conversion of the reflected optical signal into a digital signal that has relative movement coordinates of the finger in a first direction and a perpendicular second direction, compression of the relative movement coordinates of the finger by a non-linear compression characteristic curve for obtaining a compressed digital signal, transfer of the compressed digital signal to the display unit and decompression of the compressed digital signal in the display unit by a non-linear decompression characteristic curve that is inverse to the non-linear compression characteristic curve.
