Abstract
A method serves for detecting the touch contact of an operator-controlled element of a machine by a user. In order to be able to continuously and with great safety and meaning carry out the detection, it is suggested that an actual vibration characteristic (FR) of the operator-controlled element is detected during operation, which changes in dependence upon a touch contact of the operator-controlled element by a user, and is compared to at least one desired vibration characteristic (FR0), which is present in a defined state of the operator-controlled element (34, 42), and an announcement (48, 52) takes place in dependence upon the result of the comparison.
