Vehicle operation device
A vehicle operation device is provided, including: a gesture sensor configured to sense a user's hand to generate image information, and a gesture recognizer configured to recognize a gesture by using the image information and generate feature information of the recognized gesture. A controller is configured to generate vehicle state information by sensing a vehicle state and perform a control operation corresponding to the feature information, in which the gesture recognizer determines whether the gesture or the vehicle state correspond to a gesture cancellation condition by using the image information and the vehicle state information and initializes a recognition operation of the gesture when the gesture or the vehicle state corresponds to the gesture cancellation condition.
1. A vehicle operation device, comprising:
a gesture sensor configured to sense a user's hand to generate image information;
a gesture recognizer configured to recognize a gesture by using the image information and generate feature information of the recognized gesture; and
a controller configured to generate vehicle state information by sensing a vehicle state and perform a control operation corresponding to the feature information,
wherein the gesture recognizer determines whether the gesture or the vehicle state correspond to a predetermined gesture cancellation condition by using the image information and the vehicle state information, and initializes a recognition operation of the gesture when the gesture or the vehicle state corresponds to the gesture cancellation condition during the recognition operation, such that generation of a feature information by the cancelled recognition operation may be prevented.
2. The vehicle operation device of claim 1 , wherein:
the gesture sensor includes at least one of a camera capturing an image of the user's hand and a sensor sensing a motion of the hand.
3. The vehicle operation device of claim 1 , wherein:
the gesture recognizer detects the hand from the image information and tracks a motion of the detected hand to recognize the gesture.
4. The vehicle operation device of claim 3 , wherein:
the gesture recognizer tracks the motion of the hand depending on whether a pattern of the detected hand satisfies a detection condition.
5. The vehicle operation device of claim 4 , wherein:
the detection condition includes a gesture input pattern which activates a gesture input mode.
6. The vehicle operation device of claim 3 , wherein:
the gesture recognizer generates a trajectory corresponding to the motion of the hand and recognizes the gesture depending on whether the trajectory of the hand satisfies a gesture recognition condition.
7. The vehicle operation device of claim 6 , wherein:
the gesture recognition condition includes at least any one of a state in which the motion of the hand stops, a state in which the motion of the hand passes a predetermined period of time or more, and a state in which the gesture is input as an input completion pattern which inactivates the gesture input mode.
8. The vehicle operation device of claim 1 , wherein:
the gesture cancellation condition is at least any one of a situation in which the input of the gesture stops, a situation in which the gesture is input as an input cancellation pattern, a situation in which an operation of a physical button disposed in a vehicle is sensed, and a situation in which a driving environment of the vehicle is changed.
9. The vehicle operation device of claim 1 , wherein:
the gesture recognizer initializes a recognition operation of the gesture when the feature information is generated.
10. The vehicle operation device of claim 1 , wherein:
the gesture recognizer detects a specific hand pause of the user and recognizes the gesture with the detected hand pause.
