Method and device for operating a motor vehicle component by means of gestures

1. 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 ( 1 ) 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 ),

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.

2. The method as claimed in claim 1 , wherein the detecting step comprises:

detecting at least one selected from the group consisting of: (a) a movement of the input unit and (b) a state of the input unit, and 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.

3. The method as claimed in claim 1 , wherein the output of the feedback signal is terminated, or an altered feedback signal is output, as soon as a gesture has been detected.

4. The method as claimed in claim 1 , wherein the feedback signal is output as an audible, visual or haptic feedback signal.

5. The method as claimed in claim 4 , wherein the feedback signal is output as a continuous audible feedback signal.

6. The method as claimed in claim 4 , wherein the feedback signal is output as a variable audible feedback signal.

7. The method as claimed in claim 6 , 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 ).

8. The method as claimed in claim 6 , 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 ).

9. The method as claimed in claim 4 , 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 ).

10. The method as claimed in claim 1 , further comprising an activation step, wherein the feedback signal is output only if the activation step has been performed.

11. The method as claimed in claim 1 , wherein the input unit comprises a hand ( 3 ) or portions of a hand of an operator.

12. 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 ( 1 ) 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 ),

wherein the detecting step comprises:

detecting at least one selected from the group consisting of: (a) a movement of the input unit and (b) a state of the input unit, and 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, and

wherein the stored gestures contain a termination gesture, and a detected termination gesture prompts at least one selected from the group consisting of: (a) terminating the feedback signal and (b) ending the gesture input.

13. An operator control unit of a motor vehicle for operator control of a motor vehicle component by a gesture, comprising:

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

an extraction unit that extracts parameters corresponding to at least one selected from the group consisting of: (a) a state of the input unit and (b) a movement of 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 unit enters or has entered the three-dimensional operator control space ( 2 ), the feedback signal being output while the input unit is in the three-dimensional operator control space ( 2 ) and no gesture has been detected.

14. The operator control unit as claimed in claim 13 , wherein the input unit comprises a hand ( 3 ) or portions of a hand of an operator.
