technical issues to be resolved

It is an object of the present invention to provide an operating device for a vehicle and a method for operating the operating device for a vehicle, by means of which a particularly simple and comfortable operation of the operating device can be achieved.

Technical solutions

This object is solved by an operating device with the features of patent claim 1 and a method with the features of patent claim 8 . Advantageous embodiments which facilitate the development of the invention are shown in the other claims of the patent.

A first aspect of the invention relates to an operating device for a vehicle, in particular a passenger vehicle. The operating device comprises a gesture recognition unit configured to recognize at least one gesture performed by a human user of the vehicle, the operating device being configured to perform at least one function dependent on the recognition of the gesture.

In order to achieve a particularly simple and comfortable operation of the operating device, according to the invention the gesture recognition unit has at least one three-dimensional detection region which is arranged, for example, in the interior of the vehicle. The operating means are configured to perform respective functions based on the recognition of the eight gestures performed by the user within the detection area. In other words, when the user performs a corresponding gesture within the detection area, the user can implement or activate one of the functions of the operating device.

In the operating device according to the invention, the first of the gestures comprises a translational movement of the user's hand along the first movement axis in the first direction. A second of the gestures includes translational motion of the hand along the first axis of motion in a second direction opposite the first direction. In other words, the user can move their hand forward and backward along the first axis of motion within the detection area, so that by moving their hand along the first axis of motion in the first direction, the user can realize the second function in the function. One, and by moving their hand along the first axis of motion in a second direction, the user can implement the second of the functions.

A third of the gestures includes translational motion of the user's hand in a third direction along a second axis of motion, the second axis of motion being perpendicular to the first axis of motion. A fourth of the gestures includes translational motion of the hand along the second axis of motion in a fourth direction opposite the third direction. In other words, the first axis of motion and the second axis of motion are virtual axes extending perpendicularly with respect to each other. By moving their hand forward and backward along the second axis of motion within the detection zone, the user can implement the third of the functions and the fourth of the functions.

A fifth of the gestures includes translational movement of the hand in a fifth direction along a third axis of motion, the third axis of motion being perpendicular to the first axis of motion and the second axis of motion. A sixth of the gestures includes translational motion of the hand along the third axis of motion in a sixth direction opposite the fifth direction. This means that the third axis of motion is a virtual axis extending perpendicular to the first and second axes of motion. By moving their hand forward or backward along the third axis of motion within the detection zone, the user can achieve the fifth of the functions and the sixth of the eight functions.

In addition, the seventh of the gestures includes a rotational movement of the hand around the third movement axis in a first rotational direction, the first rotational direction being the seventh direction. The eighth of the gestures includes rotational movement of the hand around the third axis of motion in a second rotational direction opposite to the first rotational direction, the second rotational direction being an eighth direction. For example, by rotating their hand left and right about the third axis of motion within the detection area, the user can implement the seventh and eighth of the functions of the operating device.

Since the user can very easily perform gestures with his hand within a detection range that can be kept very small, the user can operate the operating device according to the invention particularly comfortably and easily. Furthermore, the gestures described are very simple inputs by means of which complex systems such as operating devices can be operated very simply.

In an advantageous embodiment of the invention, the gesture recognition unit is configured to switch from the locked state to the unlocked state upon recognition of a ninth gesture performed by the user within the detection area, the gesture recognition unit being configured to detect the ninth gesture. A ninth gesture includes movement of two fingers of the hand towards each other. In other words, the user performs the ninth gesture by moving two fingers of their hand towards each other within the detection area. In the locked state, the recognition of the first eight gestures is omitted. In other words, when the gesture recognition unit is in the locked state, the eight functions corresponding to the first eight gestures cannot be realized by performing the first eight gestures. In the unlocked state, the gesture recognition unit is ready to recognize the first eight gestures, so that in the unlocked state, the user can realize eight functions by performing the corresponding first eight gestures within the detection area. As a result, the risk of incorrect operation can be kept particularly low since the user first needs to switch the gesture recognition unit from the locked state to the unlocked state in order to realize the eight functions. However, the gesture recognition unit is configured to detect a ninth gesture in the locked state.

In a particularly advantageous embodiment of the invention, the gesture recognition unit is configured to switch from the unlocked state to the locked state according to a tenth gesture performed by the user within the detection area, the gesture recognition unit being configured to recognize the tenth gesture, wherein the tenth A gesture consists of the movement of two fingers away from each other. In other words, when the user moves their fingers away from each other within the detection area, the gesture recognition unit is switched from the unlocked state to the locked state. Thus, the gesture recognition unit can be switched particularly easily from the unlocked state to the locked state, so that the risk of incorrect operation can be kept particularly low.

In a further advantageous embodiment of the invention, the gesture recognition unit is configured to remain in the unlocked state as long as the fingers are kept together. This means that as soon as the user opens their fingers, ie moves their fingers away from each other, the gesture recognition unit switches from the unlocked state to the locked state. This also means that as long as the user keeps their fingers together, the gesture recognition unit is ready to recognize the first eight gestures. Thus, the risk of mishandling can be kept particularly low.

In a further advantageous embodiment of the invention, the operating device is configured as a navigation system for the vehicle. Such navigation systems are very complex systems and their operation can often be cumbersome. However, the operating device according to the invention allows a particularly simple and comfortable operation of any complex system. Thereby, the user can operate the navigation system in a quick and simple manner without being distracted from traffic.

For example, a navigation device includes a display unit configured to display a virtual map, and functions related to adjusting the virtual map. In other words, the user can adjust the virtual map by performing the first eight gestures described. For example, the area represented by the virtual map can be changed and/or enlarged and/or scaled down by performing the first eight gestures. Furthermore, for example, a user may perform gestures to confirm or reject an input and/or navigate through a manual structure comprising different manuals and/or tabs and/or menu interfaces by performing said gestures.

A second aspect of the invention relates to a vehicle, in particular a passenger vehicle, comprising an operating device according to the invention. The advantages and advantageous embodiments of the first aspect of the invention are considered to be advantages and advantageous embodiments of the second aspect of the invention and vice versa.

A third aspect of the invention relates to a method for operating an operating device of a vehicle, the operating device comprising a gesture recognition unit by means of which at least one gesture performed by a user of the vehicle can be recognized, wherein depending on the recognition of the gesture, the operating device performs at least a function.

In order to achieve a particularly simple and comfortable operation of the operating device, according to the invention the gesture recognition unit has at least one three-dimensional detection area in which the operating device performs the respective function when the human user performs the recognition of eight gestures within the detection area. Wherein, the first of the gestures includes translational motion of the user's hand along the first motion axis in the first direction, and the second of the gestures includes the hand along the second motion axis in the second direction opposite to the first direction The third of the gestures includes the translation of the user's hand in the third direction along the second axis of motion, the second axis of motion is perpendicular to the first axis of motion, and the fourth of the gestures includes the hand moving along the second axis of motion The second movement axis is a translational movement in a fourth direction opposite to the third direction, the fifth of the gestures includes a translational movement of the hand along the third movement axis in a fifth direction, the third movement axis is perpendicular to the first movement axis and The second axis of motion, the sixth of the gestures includes translational motion of the hand along the third axis of motion in a sixth direction opposite to the fifth, the seventh of the gestures includes the first rotation of the hand around the third axis of motion The eighth of the gestures includes a rotational movement of the hand around a third movement axis in a second rotational direction opposite to the first rotational direction. Advantages and advantageous embodiments of the first and second aspects of the invention are considered to be advantages and advantageous embodiments of the third aspect of the invention and vice versa.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawings.

detailed description

The same elements or elements with the same function are denoted by the same reference symbols in the figures.

FIG. 1 shows a schematic perspective view of an operating device in the form of a navigation system for a vehicle in the form of a passenger vehicle. The navigation system comprises a display unit 10 configured to display eg a virtual map 12 of the environment. In other words, at least part of the earth's surface is represented by the virtual map 12 , wherein a human user of the navigation system can adjust said part to be represented by the virtual map 12 , ie to be displayed by the display unit 10 .

In this case, the display unit shows a character or lens barrel with an outer peripheral surface 14 forming a three-dimensional virtual map 12, so that, for example, buildings and/or mountains arranged in the portion displayed by the virtual map 12 are represented in a three-dimensional manner . Furthermore, FIG. 1 shows the front surface 16 of the lens barrel or character.

In order to achieve a particularly simple and comfortable operation of the navigation system, the navigation system comprises a gesture recognition unit 18 configured to recognize a plurality of gestures performed by a human user, wherein the navigation system is configured to perform a function depending on the recognition of the respective gestures.

The gesture recognition unit 18 has a three-dimensional detection area 20 arranged in the interior of the passenger vehicle, and the operating device is configured to perform a respective function based on the recognition of the first eight gestures performed by the user within the detection area 20 . The first of the first eight gestures includes a translational movement of the user's hand along a first axis of motion 22 in a first direction shown by directional arrow 24 . The second of the first eight gestures involves translational movement of the hand along the first axis of motion 22 to a second direction opposite to the first direction and shown by directional arrow 26 . The third of the first eight gestures involves translational movement of the user's hand along a second axis of motion 28 , which extends perpendicular to the first axis of motion 22 , in a third direction shown by directional arrow 30 . The fourth of the first eight gestures includes translational movement of the hand along the second axis of motion 28 in a fourth direction opposite to the third direction and shown by directional arrow 32 . The fifth of the first eight gestures involves translational movement of the hand along a third axis of motion 34 which is perpendicular to the first axis of motion 22 and the second axis of motion 28 in a fifth direction shown by directional arrow 36 extend.

The sixth of the first eight gestures includes translational movement of the hand along the third axis of motion 34 in a sixth direction opposite to the fifth direction and shown by directional arrow 38 . The seventh of the first eight gestures involves a rotational movement of the hand about the third axis of motion 34 in the first rotational direction indicated by the directional arrow 40 . Furthermore, the eighth of the first eight gestures includes a rotational movement of the hand about the third axis of motion 34 into a second rotational direction opposite to the first rotational direction and indicated by the directional arrow 42 . Therefore, a gesture operation of four plus four is realized to operate the navigation system.

For example, the first axis of motion 22 corresponds to the lateral direction of the vehicle. The second axis of motion 28 corresponds to the vertical direction of the vehicle and the third axis of motion 34 corresponds to the longitudinal direction of the vehicle. Furthermore, the virtual map 12 and/or the lens barrel may be moved left and right, for example, by moving their hand along the first axis of motion 22, ie left and right. For example, by moving the hand along the second axis of motion 28, ie, up and down, the virtual map 12 and/or the lens barrel can be moved up and down. For example, the scale of the virtual map 12 can be enlarged by rotating the hand around the third axis of motion 28 in the first rotation direction, ie clockwise. Furthermore, for example, the scale of the virtual map 12 can be reduced by rotating the hand around the third axis of motion 34 in the second rotation direction, ie, counterclockwise.

Alternatively or additionally, the user may navigate through the menu structure of the graphical user interface (GUI) of the navigation system by performing gestures within the detection area 20 . For example, the user may confirm an input into the navigation system by moving the hand along the third axis of motion 34 in a fifth direction, ie forward. Additionally, for example, by moving the hand along the third axis of motion 34 in a sixth direction, ie backwards, the user can reject an input and/or navigate to a previous menu interface of the navigation system. The gesture recognition unit 18 is configured to switch from the locked state to the unlocked state based on recognition of a ninth gesture performed within the detection area 20 as shown in FIG. mutual motion such that the respective ends of finger 44 and finger 46 meet at a point 50 . In the locked state, the recognition of the first eight gestures is omitted. In the unlocked state, the gesture recognition unit 18 is ready to recognize only the first eight gestures described.

The gesture recognition unit 18 is configured to switch from the unlocked state to the locked state according to the recognition of the tenth gesture described in FIG. 3 , the tenth gesture comprising a movement of the finger 44 and the finger 46 away from each other. As shown in FIG. 3 , the tenth gesture is performed by spreading the fingers 44 and 46 such that the ends of the fingers are arranged at a distance from each other. In this case, finger 44 is the index finger of hand 48 and finger 46 is the thumb of hand 48 .

Furthermore, acoustic and optical feedback to the user is achieved by playing respective sounds and/or changing the color of the front surface 16 according to the recognition of the gesture. For example, in the locked state, the front face 16 is gray as a default color and the gesture recognition unit 18 scans in. Preferably, in the locked state, the gesture recognition unit 18 cannot recognize any gestures except the ninth gesture. Therefore, when the user performs the ninth gesture, that is, moves the finger 44 and the finger 46 toward each other in the detection area 20 , the gesture recognition unit 18 switches from the locked state to the unlocked state. For example, when the user moves finger 44 and finger 46 into detection area 20 and then gesture recognition unit 18 detects that finger 44 and finger 46 are arranged spaced apart from each other, then a brief activation sound is played and front surface 16 rotates rapidly. The Color effect changes its color from gray to green. When the user moves finger 44 and finger 46 towards each other, i.e. performs a ninth gesture and the gesture recognition unit 18 recognizes the ninth gesture, a brief activation sound is played and the rapidly rotating color effect is stopped, causing the front surface 16 or its green color to stabilize .

Gesture recognition unit 18 is kept unlocked as long as finger 44 and finger 46 , in particular the fingertips, remain together within detection region 20 . The user can then execute the first eight gestures described in order to realize the corresponding eight functions of the navigation system. For example, whenever the gesture recognition unit 18 recognizes one of the first eight gestures, a corresponding adjustment sound is played to inform the user that the respective gesture is correctly detected. When the user opens finger 44 and finger 46 , ie performs a tenth gesture, gesture recognition unit 18 switches from an unlocked state to a locked state, wherein the front surface 16 changes its color from green back to a static gray.

A navigation system is an operating device with several different functions. In this case, the functionality is related to adjusting the virtual map 12 . Therefore, navigation systems are very complex systems. However, this complex system can be operated in a particularly simple and comfortable manner by the user by performing the gestures described.
