Abstract

A method for the operation of a capacitive, matrix touchscreen for use in a motor vehicle, wherein touching the matrix touchscreen in the region of a matrix element produces a signal level associated with the matrix element, wherein the extent of a signal level which is produced by touching the matrix touchscreen in the region of the matrix element and which is associated with the matrix element is altered, and wherein the thus modified signal levels of two adjacent matrix elements are taken as a basis for determining whether the two matrix elements are being touched as part of collective areal touching of the matrix touchscreen.
