1. A method of operating a touch-sensitive operator control unit for a vehicle, comprising:
- displaying a graphical symbol on the operator control unit;
detecting the presence of input means in a predefined first area in front of the operator control unit in an area of the displayed graphical symbol, wherein the predefined first area comprises an area parallel above a surface of the operator control unit; and
generating a predefined first audio output comprising a context-specific sound associated with a vehicle function of the graphical display symbol in response to the detected presence of the input means; and
detecting direct contact of the input means with the displayed graphical symbol to cause execution of the vehicle function; and
generating another predefined audio output comprising a context-specific sound associated with the vehicle function of the graphical display symbol in response to the detected direct contact with the displayed graphical symbol.

Abstract
User interface and process to support a user in the operation of a touch-sensitive control unit. A presence of a means of input, such as a finger of the user, is detected in a predefined first area relative to the control unit. In response to the detection, an acknowledgement may be produced via a predefined first audio output including a first sound sign, which is associated in a context-specific manner with a button displayed on the control unit.

9. A Human Machine Interface installed in a motor vehicle, comprising:
-
a touch-sensitive operator control unit configured to display a graphical symbol on the operator control unit; a detection device configured to detect the presence of input means in a predefined first area in front of the operator control unit in an area of the displayed graphical symbol, wherein the predefined first area comprises an area parallel above a surface of the operator control unit, detect direct contact of the input means with the displayed graphical symbol to cause execution of the vehicle function; and a processing device, operatively coupled to the detection device and the operator control unit, wherein the processing device is configured to generate a predefined first audio output comprising a context-specific sound associated with a vehicle function of the graphical display symbol in response to the detected presence of the input means, and generate another predefined audio output comprising a context-specific sound associated with the vehicle function of the graphical display symbol in response to the detected direct contact with the displayed graphical symbol. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
