## Abstract

Methods for recognizing an input of a person with a sensor, wherein the input is recognized by the sensor by at least one gesture of the person assigned to the input, wherein a first gesture for sensing the input is applied, said gesture being sensed by the sensor, wherein a functionality of the sensor for sensing the first gesture is checked, wherein, in the event that the functionality for recognizing the first gesture is not given, alternatively a second gesture is selected and assigned to the input, wherein a switch is made from the first gesture to the second gesture for recognizing the input by the sensor.

## Claims

### Claim 1

A method for recognizing an input of a person comprising:
a sensor,
wherein the input is recognized by the sensor by at least one gesture of the person assigned to the input, wherein a first gesture for sensing the input is applied, said gesture being sensed by the sensor, wherein a functionality of the sensor for sensing the first gesture is checked, wherein, in the event that the functionality for recognizing the first gesture is not given, alternatively a second gesture is selected that is or will be assigned to the input, wherein a switch is made from the first gesture to the second gesture for recognizing the input by the sensor.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the sensor generates a signal upon sensing the first gesture, wherein a first signal is assigned to the first gesture, wherein a quality of the signal generated is controlled by comparison with the first signal, the quality of the signal generated being used to determine whether or not the functionality of the sensor for sensing the first gesture is given.

### Claim 3 (depends on 2)

The method of claim 2, wherein the second gesture is defined, wherein a second signal is assigned to the second gesture.

### Claim 4

System for recognizing an input of a person comprising:
a sensor,
wherein the system has said sensor which is adapted to recognize the input by sensing at least one gesture of the person assigned to the input, wherein a first gesture for sensing the input must be applied, wherein the sensor is adapted to sense the first gesture, wherein the system is adapted to check a functionality of the sensor for sensing the first gesture, wherein, in the event that the functionality for sensing the first gesture is not given, the system is adapted to alternatively select a second gesture for recognizing the input, assign it to the input, and make a switch from the first gesture to the second gesture for recognizing the input by the sensor.

### Claim 5 (depends on 4)

The system according to claim 4, which has a computing unit which is connected to the sensor, wherein the sensor is adapted to generate, in response to sensing a gesture, at least one signal assigned to the gesture and to transmit it to the computing unit.

### Claim 6 (depends on 5)

The system according to claim 5, wherein the computing unit is adapted to control a quality of the at least one signal which is transmitted to it by the sensor and to decide based on the determined quality of the signal assigned to the first gesture, whether or not the functionality of the sensor for sensing the first gesture is given.

### Claim 7 (depends on 5)

The system according to claim 5, wherein the computing unit is adapted to select the second gesture and to switch the sensor from the first gesture to the second gesture for recognizing the input.

### Claim 8 (depends on 4)

The system according to claim 4, for a motor vehicle.

### Claim 9 (depends on 6)

The system according to claim 6, wherein the computing unit is adapted to select the second gesture and to switch the sensor from the first gesture to the second gesture for recognizing the input.

### Claim 10 (depends on 5)

The system according to claim 5, for a motor vehicle.

### Claim 11 (depends on 6)

The system according to claim 6, for a motor vehicle.

### Claim 12 (depends on 7)

The system according to claim 7, for a motor vehicle.
