  According to the present invention, a driver can travel toward a destination by displaying a direction indication display in a three-dimensional manner on a substantially horizontally displayed map, and preventing window reflection on the front windshield of the map display. It is possible to easily and surely assist in grasping the position of the host vehicle and determining the course when the vehicle is driven, to reduce the burden of driving the vehicle, and to maintain the safety of driving the vehicle.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a functional block diagram illustrating an example of a main configuration related to the vehicle display apparatus according to the first embodiment. As shown in FIG. 1, the vehicle display device according to the present embodiment includes an operation display 100, a display control device 70, and a 3D display 40 that can display an object in 3D. Moreover, the vehicle-mounted apparatus 80 which implement | achieves predetermined functions, such as an air-conditioner function and an audio function, is provided.

  The display control device 70 is configured around a microcomputer. That is, the display control device 70 includes a CPU that performs various processes in accordance with a given execution program, a memory (for example, ROM, RAM, EEPROM, etc.) that stores an execution program for the CPU, image data, calculation results, a timer, a counter, It has an input / output interface. The CPU, memory, and input / output interface are connected to each other by a data bus. Various operations / functions of the display control device 70 described below are realized by programs executed by the CPU.

  The display control device 70 communicates with the operation display 100 by wireless or wired. Upon receiving various switch signals from the operation display 100, the display control device 70 performs switching of the display screen (generation of various operation menu images) on the stereoscopic display 40 and other control ECUs (for example, car Signals corresponding to various switch signals are sent to navigation ECU, audio ECU, air conditioner ECU, etc. The other control ECU responds to a signal from the display control device 70 and controls the in-vehicle device 80 (for example, an audio and an air conditioner) so as to realize a function according to various switch signals.

  The display control device 70 communicates with the stereoscopic display 40 by wireless or wired. In this example, the three-dimensional display 40 is a three-dimensional display that includes a display arranged substantially horizontally and can display an object three-dimensionally on the horizontal plane.

  FIG. 2 is a perspective view showing the stereoscopic display 40 and the operation display 100 of the vehicle display device according to the present embodiment. The three-dimensional display 40 is disposed substantially horizontally above the instrument panel 10 in front of the vehicle. On the upper surface of the console 20, an operation indicator 100 having an operation display is installed.

  The stereoscopic display 40 is a display that can display a stereoscopic image from a horizontally placed screen. In recent years, the development of a display in which an image can be viewed stereoscopically even with the naked eye is progressing. In particular, the development of a naked-eye stereoscopic display technology that can display a stereoscopic image on a horizontally placed screen has attracted attention. This is called an “integral imaging method”, and is based on the “lenticular method” well known as a naked-eye stereoscopic technique, and has a parallax number of 14 instead of the conventional two-parallax stereoscopic vision. It is increased up to ˜16 to increase the parallax angle and improve the image quality. By using such a flat-type stereoscopic display, a three-dimensional display capable of stereoscopically displaying an arrow symbol or a landmark symbol to be emphasized on map information displayed on a flat screen. 40 can be made.

  The advantage of having the map display screen flat is that, first of all, the vehicle occupant can obtain map information in a form closer to the actual scene, so the burden of considering the course to the destination while driving Is overwhelmingly reduced. That is, when a human is reading a map, on the two-dimensional plane, from the map information given as an image seen from the sky, where is his destination, where is he currently located, Read what kind of route you have to follow to reach the destination, and convert it into information about what will happen on the road where you are, and determine the course Yes. In other words, just looking at the map does not mean that you can immediately know where you are and where you should go, but you are moving from the map information where the north is up or the direction of travel is up. I follow the thought process of thinking about what the relationship between the direction and the direction of the destination will actually be on the road where I am, and proceeding to the course to be followed. Therefore, as in the present embodiment, there is a planar reduced map similar to the actual scene that the vehicle is traveling and is visually recognized by the occupant, and the direction to proceed on the map is three-dimensionally emphasized and instructed. If you give it, the thought process of conversion between this map and the actual road can be omitted, the burden of reading the map will be greatly reduced, and it will be very convenient for passengers.

  A second advantage of displaying map information on a substantially horizontal screen is that a display for displaying a map can be installed substantially horizontally so that the size of the display screen can be made larger than that of a conventional vertical display. Can be mentioned. That is, in the case of a vertically placed screen, if it is too large, there is a risk of obstructing the field of view of an occupant such as a driver. However, if the screen is installed horizontally or horizontally, there is no possibility of obstructing the field of vision in front of the occupant, so that a large screen can be used and map information can be displayed in a larger scale. If the reduction ratio is the same as that of the vertical screen, it is possible to display farther map information, and if the reduction ratio is reduced, a larger and easier-to-read screen display can be provided to the occupant.

  In addition, although the three-dimensional display 40 in a present Example is arrange | positioned substantially horizontally, the near side near a passenger | crew is lowered a little so that a map may be easy to see, and a map should face a passenger | crew a little inside. preferable. If you are facing outwards, the display of the map will face the opposite side of the line of sight, and if it is completely horizontal, the display screen will be almost seen from the side, making it difficult to see the entire map. . Moreover, since the instrument panel 10 is also slightly lowered toward the occupant, it is functionally and designally preferable to have the same inclination as the instrument panel 10 so as to be unified. Because. The degree of inclination may be set so as to be easy to see within a range in which a horizontal feel remains on the display of the stereoscopic display 40. Since the actual scenery spreading in front of the occupant is in the horizontal direction, the higher the level, the better the contrast between the map image displayed on the screen of the stereoscopic display 40 and the actual scenery. Therefore, it may be determined to have an appropriate inclination from the viewpoint of easy visual recognition of the screen of the stereoscopic display 40 and the actual landscape. Further, an appropriate inclination may be fixed, or a movable mechanism that allows the occupant to arbitrarily set the inclination may be provided so that the occupant can set a desired inclination.

  Also, on the map of the three-dimensional display 40, a three-dimensional arrow 43 indicating the direction of the course of the vehicle and a three-dimensional mark 44 that can be a traffic sign such as a signal or a specific building are displayed together with the map information. Can be highlighted. Since the three-dimensional display 40 arranged in a substantially horizontal plane displays three-dimensional arrows 43 and marks 44 such as signals so as to rise up, the presence of these direction indications is simply displayed on the plane screen. Compared with the conventional display method in which only an arrow is displayed, it is emphasized significantly. Since a three-dimensional direction indication display comes out from a map on a two-dimensional plane screen almost parallel to the line of sight of the occupant, the driver can clearly recognize the direction indication display in the field of view and is alerted. The possibility of overlooking the direction indication display is extremely reduced. Thus, the navigation function can be achieved extremely effectively by combining the two-dimensional map display and the three-dimensional display for three-dimensional direction indication. Further, since the map displayed on the display screen of the stereoscopic display 40 has a sense of depth in the same direction as the scenery that the driver actually sees as described above, the three-dimensionally displayed arrows 43 and landmarks are displayed. 44 has the same effect as that displayed on the road that is actually running. In other words, with the same display method as taken from the air in the past, even if a direction indication arrow appears on the map, it is necessary to perform a conversion thinking work that considers the direction of the information once on the actual road. However, according to the present embodiment, such conversion thinking work becomes unnecessary, and the burden of considering the course during driving is remarkably reduced. It should be noted that the color and shape of the solid arrow 43 and the solid mark 44 may be devised to make the display stand out. This is because, in order to effectively perform the navigation function, it is preferable to emphasize important information related to the route to the destination to enhance the degree of attention and to provide it to a passenger such as a driver.

  In addition, the stereoscopic display 40 may perform two-stage display in which the scale of the map information is changed on the left screen 41 and the right screen 42. For example, the left screen 41 employs a map with a large scale ratio so that a rough path to the destination of the vehicle can be understood, and the right screen 42 displays map information around the vehicle on which the vehicle is traveling. However, detailed direction indication information such as the three-dimensional arrow 43 and the three-dimensional mark 44 indicating which intersection is to be bent in which direction may be provided in a three-dimensional manner. A driver or other vehicle occupant needs to understand the current position based on information in a large direction to the destination, and instantly decides where to go to the intersection in front of him. Because it is necessary to go to. In this embodiment, an example of using the above-mentioned “integral imaging method” flat display is described as an example, but a stereoscopic display capable of displaying a stereoscopic image by placing it flat is also available. If so, any type or form can be used suitably.

  The operation display 100 is disposed on the upper surface of the console 20 and is used to operate the stereoscopic display 40 and the in-vehicle device 80. The operation display 100 may be operable by performing a gesture gesture in a predetermined space area 101. For example, when raising the temperature of an air conditioner, increasing the volume of an audio device, or enlarging the map magnification, move your hand from left to right while looking at a predetermined reference point in a predetermined space area. Or may be operated by performing gesture gestures such as bringing a hand from the bottom to the top. The operation space area 101 for performing the gesture gesture operation for these operations is located on the upper surface of the console 20 and on the side of the driver. The person cannot see clearly. Therefore, the driver must operate the vehicle display device in the peripheral field of view that is not clearly visible, and it is very difficult to perform this operation in the air. Therefore, it is desirable that there is a target for the predetermined space area 101. As the target, a virtual target based on a stereoscopic image may be used. That is, for example, an integral imaging display capable of displaying a stereoscopic image as described above is used as the operation display 100, and a substantially cylindrical stereoscopic image 102 extends upward from the operation display 100 as a virtual target. Then, this expands and contracts and swings to attract the operator's attention and promote recognition, and the predetermined operation space area 101 is shown. Using this as a clue, the operator enters the operation space area 101. You may comprise so that it can carry a hand easily. As described above, the target stereoscopic image 102 is provided in the region of the peripheral visual field from the line of sight during driving when the driver operates the display 100 for operation when the operation display 100 is arranged on the upper surface of the console 20. In many cases, there is no idea where in the space to perform the operation for the operation, but it may be ambiguous. If there is a target as shown, it is possible to avoid the inconvenience of performing an operation operation in a completely misplaced place, and a desired operation can be performed even while the vehicle is driving. Note that the stereoscopic image 102 serving as a virtual target is intended to make the driver recognize its presence and approximate position, and therefore, a conspicuous shape and color that do not interfere with driving are preferable.

  FIG. 3 is a diagram showing the vehicle display device according to the present embodiment provided with a louver. 3A is a perspective view, and FIG. 3B is a cross-sectional view. On the upper surface of the instrument panel 10 in front of the vehicle, there is a stereoscopic display 40 arranged substantially horizontally as described above, and a louver 30 is provided in a space above and below the front windshield 60. ing. As described with reference to FIG. 2, since the display screen for displaying the map of the stereoscopic display 40 is placed almost horizontally, there is a problem that if the display is displayed as it is, the display of the map is displayed on the front windshield 60. There is a fear. Therefore, in order to avoid such a problem, a louver extending substantially in the horizontal direction is arranged above the stereoscopic display 40 to solve the problem of map window projection. As for the entire louver 30, the front windshield 60 can be shielded so that an image projected from the entire display of the stereoscopic display 40 can be shielded from being projected on the front windshield 60 in a relative positional relationship with the front windshield 60. You may install in the angle close | similar to the inclination of this, or the angle which makes the intermediate position of both. The reason why the louver extending in a substantially horizontal direction is used without using a simple single plate is to secure the occupant's field of view as shown in FIG. That is, if a single plate is placed above the stereoscopic display 40, the lower part of the front windshield 60 is covered with the single plate from the inside of the vehicle, and the lower part of the front view of the occupant may be obstructed. There is. Therefore, if a louver 30 that is substantially horizontal and substantially parallel to the line of sight of the occupant is used, the sight of the front of the occupant is not obstructed, and the window projection of the map in the vertical direction has a certain width in the vertical direction. Therefore, it is possible to prevent the map from being projected while securing the field of view in front of the occupant. This eliminates the problem when the map image is stereoscopically displayed on the horizontal display, so that the occupant is emphasized by the map display in a form close to a real scene on a substantially horizontal two-dimensional large screen and the stereoscopic display. Only the advantage of easy understanding of the course to be taken, which arises from the combination with the direction indication display of the dimension, can be fully enjoyed. Note that the louver 30 may have a structure in which short slats having a minimum length for preventing window reflection are stacked. This is because it is preferable that the element that blocks the field of view is made as small as possible as long as it prevents window reflection. The louver 30 may be variable so that the angle can be adjusted. Louver angle adjustment means such as the operation handle 31 and the operation lever 32 may be provided in an appropriate place where the operation can be performed so that the angle can be adjusted manually. For example, the rotary operation handle 31 or the slide type operation lever 32 is provided in the vicinity of the middle height of the lateral frame on the operator side of the outer frame of the louver that can be easily operated by reaching the operator. Also good. As long as the louver angle can be arbitrarily changed, the type, type, and mounting position are not limited. In addition, an electric drive mechanism may be provided and operated electrically by an operation switch. The operation switch may be operated in a predetermined operation space area 101 of the operation display 100, for example.

  FIG. 4 is a perspective view showing the inside of the vehicle provided with means for detecting the seat height of the occupant. In order to change the angle of the louver 30 described with reference to FIG. 3 to detect the occupant's sitting height and automatically perform the detection based on the detection result, a seat height detecting means is provided. That is, in the vehicle, a seat height sensor 90 is provided on the seat, and a reflection type object detection sensor 91 is provided at the frame of the door next to the seat. The seat height sensor 90 detects the position of the shoulder when the occupant is seated in the seat by means of 4 to 6 sensor plates arranged in the seat back, and calculates the seat height therefrom. Since the waist to shoulder are in contact with the seat back and the position away from the seat back is the shoulder position, the seat height can be roughly calculated from the waist to shoulder height. The sitting height sensor may be detected by the presence or absence of a load, or may be detected by another appropriate method. The object detection sensor 91 has a plurality of sensors arranged in a vertical direction at different heights, for example, installed on a door frame next to the seat, and the head reflects the infrared rays emitted from the object detection sensor 91. You may make it determine in which height it exists depending on whether there exists. Although not shown, a sensor capable of measuring a distance such as an ultrasonic sensor may be provided on the ceiling above the passenger's seat in the front vehicle, and the overhead distance from the ceiling may be measured to calculate the seat height. One of these sensors may be used alone, or a plurality of these sensors may be used in combination if necessary. For example, if a sensor for detecting the position of the shoulder and a sensor for detecting the position of the head are used in combination, a more accurate eye position can be calculated, and the angle of the louver of the louver 30 can be adjusted more appropriately. In a more generally known method, a camera for photographing an occupant can be provided, and the eye height itself can be calculated by processing the image. Since the approximate eye height of the occupant of the vehicle ahead can be determined from the seat height calculated using the above-described sensor, the angle of the louver 30 is determined based on this. When the angle of the louver 30 is set to an angle along the line of sight during driving, it is preferable because the louver shields the driver's field of view most. The angle of the louver 30 may be calculated based on the seat position and the eye height accurately, and the angle of the louver 30 may be determined based on the angle. However, it is simplified to some extent, and a height reference is provided in about 3 to 6 levels. The angle of the louver 30 may be determined. In addition, when a passenger | crew has both a driver's seat and a passenger seat and seat height differs remarkably, you may make it match | combine preferentially to a driver | operator. This is because it is preferable to give priority to the driver's field of view for safety of vehicle travel.

  FIG. 5 is a perspective view showing an example of the details of the operation indicator 100 of the vehicle display device according to the present embodiment. The same components as those in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted. The difference from FIG. 2 is that a space operation panel 103 is added. This is because, when other functions such as an air conditioner function, an audio function, and a telephone function of the in-vehicle device 80 are operated by the operation display 100, an operation switch is spatially displayed in a predetermined operation space area 101. Thus, the vehicle-mounted device 80 or the stereoscopic display 40 can be operated using this.

  For example, a space operation composed of an air conditioner function operation switch, an audio function operation switch, a telephone function operation switch, and a navigation function destination search switch at a predetermined position in a predetermined operation space area 101 from the left. The panel 103 is displayed by drawing a space at a specific position. If the operator's hand reaches the place of the operation switch having these predetermined functions, the predetermined function may be realized. For realizing these functions, it is sufficient to use a means that can detect a position in the hand space and realize a predetermined function based on the detected position. For example, a proximity sensor is provided at a predetermined operation switch. Alternatively, a predetermined function corresponding to when the hand enters a predetermined switch area for image recognition or the like may be realized, or light or infrared rays or the like in the space of the predetermined switch area may be realized. It may be possible to detect that a hand has entered the predetermined switch region by passing a sound wave such as a sound wave. In addition, any other types and types of detectors can be applied as long as the detector has a function capable of detecting that a hand has entered a predetermined switch region from a remote location. Further, for example, air conditioner temperature, audio volume, map magnification switching, cursor movement on the map, and the like are operations in which a hand crosses the reference object 104 from left to right in a predetermined operation space area 101. It is good also as a structure which shifts from small to large according to it at the time. In this way, when it is desired to adjust the amount of a specific item or to perform an operation of moving something, the stereoscopic display device corresponds to the operation of moving the hand within a predetermined operation space area 101. 40 or the in-vehicle device 80 is operated, the operator operates the stereoscopic display 40 or the in-vehicle device 80 with an operation close to one's own sense while driving the vehicle with less burden of thinking for performing the operation. This reduces the operational burden and allows you to focus more on driving. Such a movement of the hand may be detected by using a sensor capable of detecting the movement of the reference object 104, or using image recognition, motion recognition, or the like. In addition, as described with reference to FIG. 2, the virtual target 102 as a target is displayed as a three-dimensional image so that the operator can easily grasp the position of the predetermined operation space area 101, and is operated by expanding and contracting or swinging. May be configured to draw the attention of the person. Thus, according to the present embodiment, since the stereoscopic display 40 or the in-vehicle device 80 can be operated by the gesture operation of the hand gesture that is close to one's own sense in the predetermined operation space area 101, the operation burden is reduced, and more You will be able to concentrate on driving.

  As described above, according to the present embodiment, a map can be displayed on a substantially horizontal plane so that the surrounding situation can be grasped in a form close to an actual landscape, and by providing a substantially horizontal louver above the stereoscopic display 40, The problem of window projection on the map screen can also be solved. In addition, since a three-dimensional direction indication display such as a three-dimensional arrow 43 and a three-dimensional mark 44 is displayed on the map displayed on the three-dimensional display 40, the driver's attention is drawn and the course to be taken smoothly toward the destination is displayed. Can be taken. Furthermore, since the virtual target 102 can be displayed in a three-dimensional manner on the operation display 100 and a predetermined operation space 101 for performing a gesture operation can be shown to the operator, high operability can be obtained.

  FIG. 6 is a diagram illustrating details of screen display of the stereoscopic display 40 of the vehicle display device according to the second embodiment. The basic configuration is the same as that of the vehicular display device according to the first embodiment, and the same components are denoted by the same reference numerals and description thereof is omitted. In this embodiment, the screen of the three-dimensional display 40 is different in that not only the three-dimensional arrow 43 and the three-dimensional mark 44 for indicating directions but also all the components on the map such as buildings are three-dimensionally displayed. . The screen basically has a two-plane structure that is substantially divided from the center to the left and right. On one side, in order to recognize the approximate position of the vehicle and the destination, a map with a large reduction ratio and a relatively wide area can be seen. 41 is that. Since the display is on a plane, the whole is displayed in three dimensions, and a three-dimensional display such as a three-dimensional map or a diorama model is performed to show the great directionality of the vehicle. On the other hand, the remaining one side is composed of a map for showing the peripheral information closer to the vehicle in detail, and the map display 42 on the right side corresponds to FIG. Buildings and signals such as buildings are displayed in three dimensions, places close to the vehicle are also close on the map, and distant places are also displayed far away on the map, so the vehicle occupant is as if viewing from the vehicle It is possible to grasp the surrounding situation with the same feeling as the scenery seen when driving on an actual road. In this way, in a state where the surrounding situation is grasped with the same sense of depth as the actual scene, the direction indication arrow and the sign are further emphasized and displayed in a three-dimensional manner. In the right diagram of FIG. 6, an intersection with a signal where a building is built is three-dimensionally displayed, and a three-dimensional arrow 43 is further highlighted to turn the intersection to the right. If the driver actually enters the same intersection as this display and turns right as indicated by the arrow without thinking anything, he is steadily heading to the destination. That is, in the map of the conventional navigation system, for example, when a right turn guidance comes out, the right turn is made while considering the relationship with the actual road, but according to the present embodiment, the right three-dimensional display is performed. It is only necessary to turn right according to the three-dimensional arrow 43 while viewing the map, so that the driving burden is greatly reduced. Note that the solid direction instruction display such as the solid arrow 43 or the solid mark 44 in the present embodiment may use a conspicuous color, luminance, shape, or the like, compared to the solid direction instruction display in the first embodiment. Since surrounding structures such as buildings are also displayed in three dimensions and the three-dimensional direction indication display may be relatively inconspicuous, it is preferable to make the three-dimensional direction indication display more conspicuous in terms of the balance with the three-dimensional map. It is.

  According to the present embodiment, all the components on the map including buildings and the like are displayed in three dimensions, so that if the screen of the three-dimensional display 40 is viewed, the navigation function can be enjoyed as if it were a real scene. be able to. Further, since all the components on the map are three-dimensionalized, the comparison between the map and the actual scene is better than that of the first embodiment, and the map information can be recognized in a state closer to a more horizontal actual scene. Become.

  FIG. 7 is a diagram showing details of the screen display of the stereoscopic display 40 of the vehicle display device according to the second embodiment, which is different from FIG. 6. The same reference numerals as those in FIG. 6 are given, and the description of the same components is omitted. FIG. 7 is different from the screen display of FIG. 6 only in that the left screen 41 is a normal map display of a flat display. This is because for a map with a large reduction ratio that represents a large directionality, it is sufficient to check the large direction to the destination, so that the display on the screen becomes complicated and the load on the eyes is thought to be large. The display is stopped and the normal two-dimensional plane display is displayed. On the other hand, it is necessary to determine the course of the vehicle in real time for an enlarged view with a small reduction ratio. In this way, the route is guided to reduce the burden of thinking about the route while driving. According to the present embodiment, the map for confirming a large direction is a normal plan view that reduces the burden on the eyes, and all the surrounding information maps that require flexible response such as turning left and right at the intersection are all By using the three-dimensional display, it is possible to recognize in a form close to a real scene, and it is possible to more reliably prevent an error in the course of the driver.

  In both the first and second embodiments, the screen is divided at the center to provide a two-step map according to the map reduction ratio. However, traffic information such as VICS and G-BOOK is used. However, a one-screen configuration may be adopted in which the reduction ratio of the map on the screen is automatically changed according to the situation. That is, for example, because there are many signals in urban areas and the frequency of turning left and right at intersections is high, it is desirable to display the surrounding information in a form that is as close as possible to the actual scene with a small reduction ratio, while on the other hand, the traveling speed is fast in a state close to a straight line On national roads, if a map with a relatively large reduction rate and a wider area can be displayed, it is better to get a sense of distance to the target. If the display has a one-screen configuration in which the reduction rate of the map changes and the operator can arbitrarily change the reduction rate of the map, a vehicle display device that is extremely easy for the user to handle can be provided.

  FIG. 8 is a perspective view illustrating details of the operation display 100 of the vehicle display device according to the second embodiment. Other components are the same as those described in the first embodiment with reference to FIGS. 1 to 5, and the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 8A is a perspective view showing details of the operation display 100 when a CCD (Charged Couple Device) camera is used. The operation display 100 is arranged on the upper surface of the console 20, and a display capable of stereoscopic display may be used as the display as in the above-described stereoscopic display 40. The operation is performed when the operator performs a hand gesture for operation in a predetermined operation space area 101 by hand. Two CCD cameras 50 are installed on the operation display 100 side so as to image the predetermined operation space area 101. The number of CCD cameras is not limited, and may be installed at any position as long as the area of the operation space area 101 can be imaged. For example, it can be installed on the ceiling.

  For example, when the operator performs a gesture of making one finger in the predetermined operation space area 101, the vehicle display device executes the air conditioner function of the in-vehicle device 80 and makes the operation of making two fingers. After that, make sure to perform the audio function. Alternatively, a target button for executing an air conditioner function and a target button for executing an audio function may be prepared, and when a gesture pointing at the target is performed, the air conditioner function and the audio function may be realized. These operations may be realized using image recognition or motion recognition technology. That is, the operation space area 101 is configured so that it can be detected and recognized by the image recognition means 50 such as a CCD camera, and a gesture for gesture operation is recognized by performing 3D image recognition or motion recognition. Then, an operation according to the command is performed. For example, when the switch operation is set to be performed according to the number of fingers, the difference in the number of fingers is recognized as an image or a motion, and the display control device 70 responds to the motion command in accordance with the stereoscopic display. 40 or in-vehicle device 80 to realize a predetermined function. Further, when the vehicle display device is operated by a hand gesture that points to the target button, the target button such as the space switch panel 103 described in FIG. A target button is displayed on the display screen of the display device 100, an operation of pointing to the target button is performed, and a difference in pointing direction is set to be recognized as an image or an operation, and a desired response is made accordingly. You may comprise so that the function of can be implement | achieved. In this case, it is needless to say that the virtual target 102 may appear from the screen of the operation display 100 and perform operations such as expansion and contraction and swinging to attract the operator's attention.

  FIG. 8B is a diagram showing details of the operation display 100 when the proximity detection means is used. Although it is the same as the embodiment in FIG. 8A that the stereoscopic image 102 as a virtual target extends upward from the operation display device 100, expands and contracts or swings, and recognizes it with the driver's attention. The difference is that the operation command is not based on a gesture operation by hand gesture, but operates by detecting that the hand is close to each of the air conditioner function switch 105 and the audio function switch 106. That is, the driver can operate the vehicle display device according to the present embodiment by bringing his or her hand close to a switch that realizes a predetermined function. In this case, for example, the air conditioner function switch 105 and the audio function switch 106 may be three-dimensionally displayed, or may be fixed switches as long as the driver can recognize the height. However, the side of the driver on the upper surface of the console 20 enters the peripheral visual field when viewed from the driving field of view from the driver, and is not a place where the driver can visually recognize, but the display of the air conditioner function switch 105 and the audio function switch 106. Since it is easy for the driver to visually recognize the vehicle if it is at a position as high as possible, it is desirable to display it three-dimensionally so as to assist the recognition of the proximity region that is the switch region. In the present embodiment, only the air conditioner function switch 105 and the audio function switch 106 have been described in order to make the story easy to understand. However, other switches having necessary functions are provided and the same as in the present embodiment. Needless to say, it can be applied as a proximity switch having a stereoscopic display function.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.
