1. A method for detecting the touch contact of a control element of a machine by a user with which the user controls the machine, the method comprising the steps of:

  • providing at least one desired vibration characteristic (FR0, PIN0, SIN0) which is present in a defined state of said control element;

    during operation, detecting an actual vibration characteristic (FR;

    PIN;

    SIN) of said control element which changes in dependence upon a touch contact of the control element by the user;

    comparing said actual vibration characteristics (FR, PIN, SIN) to said desired vibration characteristic (FR0;

    PIN0;

    SIN0); and

    , outputting an announcement in dependence upon the result of said comparison.
