Abstract

A method for operator control of a motor vehicle component by a gesture includes: detecting the gesture being executed by an input unit of an operator in a three-dimensional operator control space, which is part of an interior of a motor vehicle; executing an operator control function associated with the identified gesture; and outputting a feedback signal as soon as the input unit enters or has entered the three-dimensional operator control space from outside the three-dimensional operator control space.

Claims

1-14. -14. (canceled)

15. A method for operator control of a motor vehicle component by a gesture, the method comprising:

detecting the gesture being executed by an input unit of an operator in a three-dimensional operator control space (2), which is part of an interior (2) of a motor vehicle;

executing an operator control function associated with the identified gesture; and

outputting a feedback signal as soon as the input unit enters or has entered the three-dimensional operator control space (2) from outside the three-dimensional operator control space (2).

16. The method as claimed in claim 15, wherein the detecting step comprises:

detecting a movement and/or a state of the input unit extracting corresponding parameters;

comparing the extracted parameters with stored gesture parameters; and

selecting an operator control function linked to said gesture if there is a sufficient match between the extracted parameters and the stored gesture parameters.

17. The method as claimed in claim 15, wherein the feedback signal is output while the input unit is in the three-dimensional operator control space (2) and no gesture has been detected.

18. The method as claimed in claim 17, wherein the output of the feedback signal is terminated, or an altered feedback signal is output, as soon as a gesture has been detected.

19. The method as claimed in claim 17, wherein the feedback signal is output as an audible, visual or haptic feedback signal.

20. The method as claimed in claim 19, wherein the feedback signal is output as a continuous audible feedback signal.

21. The method as claimed in claim 19, wherein the feedback signal is output as a variable audible feedback signal.

22. The method as claimed in claim 21, wherein the audible feedback signal is output at a variable frequency on the basis of a speed of movement of the input unit or a position of the input unit in the three-dimensional operator control space (2).

23. The method as claimed in claim 21, wherein the audible feedback signal is output at variable volume on the basis of a speed of movement of the input means or the position of the input unit in the three-dimensional operator control space (2).

24. The method as claimed in claim 19, wherein the input unit is a hand (3) and the audible feedback signal is output with a harmonic distortion on the basis of an open state of the hand (3).

25. The method as claimed in claim 15, further comprising an activation step, wherein the feedback signal is output only if the activation step has been performed.

26. The method as claimed in claim 16, wherein the stored gestures contain a termination gesture, and a detected termination gesture prompts the feedback signal to be terminated and/or the gesture input to be ended.

28. The operator control unit as claimed in claim 27, wherein the operator control unit is configured to execute the method as claimed in claim 15.

29. The method as claimed in claim 15, wherein the input unit comprises a hand (3) or portions of a hand of an operator.

27. An operator control unit of a motor vehicle for operator control of a motor vehicle component by a gestures, comprising:

a detecting unit that detects a movement by an input unit in a three-dimensional operator control space (2) that is part of an interior (1) of the motor vehicle;

an extraction unit that extracts state and/or movement parameters for the input unit;

a comparison unit that compares the extracted parameters with stored gesture parameters for gestures;

a selecting unit that selects an operator control function for the motor vehicle component, which operator control function is linked to an identified gesture; and

a feedback unit (9) that produces a feedback signal as soon as the input means enters or has entered the three-dimensional operator control space (2).

30. The operator control unit as claimed in claim 27, wherein the input unit comprises a hand (3) or portions of a hand of an operator.
