  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  An information display device shown as an embodiment of the present invention is configured as shown in FIG. 1, for example. The information display device includes a 2D / 3D display 1, an information display unit 2, an input device 3, a vehicle signal input unit 4, and a traffic jam information input unit 5. This information display device is mounted on a vehicle, for example, and presents various types of information to a vehicle occupant.

  The 2D / 3D display 1 is a multifunction display device that displays a plurality of types of information (display means). The 2D / 3D display 1 is composed of, for example, a liquid crystal display installed on an instrument panel of a vehicle. The 2D / 3D display 1 displays, for example, a menu image, various setting images, a running state image, a map image, and the like. These various images usually contain a lot of information. The 2D / 3D display 1 changes information to be recognized by the user from a two-dimensional display form to a three-dimensional display form.

  The 2D / 3D display 1 displays various information in a two-dimensional display form or a three-dimensional display form. A two-dimensional display form is a display form visually recognized in a plane. That is, the two-dimensional display form is a display form in which information is visually recognized only by image components of only the vertical direction component and the horizontal direction component. The three-dimensional display form is a display form visually recognized in three dimensions. The display form information visually recognized in three dimensions is information that visually includes image components such as depth, thickness, and height. That is, the three-dimensional display form is a display form in which a person who sees information feels not only the vertical and horizontal directions but also the depth, thickness, and height.

  The input device 3 is operated by a person viewing the 2D / 3D display 1. The input device 3 includes, for example, various buttons and a capacitive touch switch built in the 2D / 3D display 1. The input device 3 receives the operation of the operator and supplies an operation signal to the information display unit 2. By the operation signal, the information display unit 2 can acquire an operation result representing the operated content.

  The vehicle signal input unit 4 is connected to various sensors mounted on the vehicle. The vehicle signal input unit 4 is connected to, for example, a sensor that detects fuel consumption, a vehicle speed sensor, and the like. The vehicle signal input unit 4 supplies information such as vehicle speed and fuel consumption information supplied from the sensor to the information display unit 2. With the information from these vehicle signal input units 4, the information display unit 2 can acquire a change in the information. Further, the vehicle signal input unit 4 acquires occupant information such as a seat position sensor and an intelligent key, and supplies it to the interface 25. By the occupant information, the 2D / 3D display 1 can acquire the presence or absence of the occupant and the position of the occupant.

  The traffic jam information input unit 5 is connected to, for example, a VICS (registered trademark) (Vehicle Information and Communication System) receiver. The traffic jam information input unit 5 supplies the traffic information received by the VICS (registered trademark) receiver to the information display unit 2. From the traffic jam information, the information display unit 2 can recognize a change in the traffic jam information.

  The information display device may include various input units other than the vehicle signal input unit 4 and the traffic jam information input unit 5 as long as the information to be displayed on the 2D / 3D display 1 is input. Of course. The input device 3, the vehicle signal input unit 4, and the traffic jam information input unit 5 function as information acquisition means for acquiring information to be displayed on the 2D / 3D display 1.

  The information display unit 2 includes a 2D / 3D image drawing processing unit 21, a CPU (Central Processing Unit) 22, a FROM (flash memory) 23, a RAM (Random Access Memory) 24, and an interface 25.

  The interface 25 is connected to the input device 3, the vehicle signal input unit 4, and the traffic jam information input unit 5. The interface 25 performs predetermined signal processing on the information (analog signal) supplied from the input device 3, the vehicle signal input unit 4, and the traffic jam information input unit 5 and supplies the information to the CPU 22.

  The CPU 22 performs control to display various information on the 2D / 3D display 1. The CPU 22 causes the 2D / 3D display 1 to display information supplied from the interface 25, information stored in storage means such as a FROM 23 and a hard disk (not shown), and the like. The stored information such as a hard disk is, for example, a menu image, various setting images, a running state image, a map image, and the like. The CPU 22 temporarily stores information in the RAM 24 as a work area as necessary.

  The CPU 22 changes the 2D / 3D image rendering processing unit 21 so that information to be recognized by the user among the information displayed in the two-dimensional display form is changed from the two-dimensional display form to the three-dimensional display form. Control. In addition, when the information displayed on the 2D / 3D display 1 is changed, the CPU 22 preferably performs control so that the changed information is changed from the two-dimensional display form to the three-dimensional display form. Further, the CPU 22 may adjust the type or degree of the three-dimensional display form.

  The 2D / 3D image drawing processing unit 21 performs drawing processing on the information supplied from the CPU 22 as a two-dimensional image or a three-dimensional image. The 2D / 3D image drawing processing unit 21 supplies display data obtained by the drawing process to the 2D / 3D display display 1. As a result, the 2D / 3D image drawing processing unit 21 causes the 2D / 3D display 1 to display information in a two-dimensional display form or a three-dimensional display form. The 2D / 3D image drawing processing unit 21 converts information to be recognized by the user from information displayed in the two-dimensional display form on the 2D / 3D display display 1 from the two-dimensional display form to the three-dimensional display form. The drawing process is performed so as to be changed. That is, only a part of the displayed information is changed from the two-dimensional display form to the three-dimensional display form.

  Next, an information display operation by the information display device configured as described above will be described with reference to the flowchart of FIG.

  First, in step S <b> 1, the information display device acquires occupant information such as a seat position sensor and an intelligent key by the vehicle signal input unit 4.

  In next step S <b> 2, the CPU 22 of the information display unit 2 acquires 3D display setting information at the time of previous activation from the FROM 23. 3D display setting information is acquired. This 3D setting display setting information is setting information for identifying which information is displayed in a three-dimensional display form. This 3D setting display setting information may be previously set, or may be changeable by the user.

  In the next step S3, the information display device sets a 3D display item that specifies information to be displayed in a three-dimensional display form according to the occupant information acquired in step S1 and the 3D setting display setting information acquired in step S2. To do. Specifically, the information display device displays, for example, a 3D display item to be displayed in a three-dimensional display form among a large amount of information included in a menu image, various setting images, a running state image, and a map image, which will be described later. Set.

  In the next step S4, the information display unit 2 determines whether or not the seat position has been changed based on a signal from the seat position sensor acquired from the vehicle signal input unit 4. If the sheet position has been changed, the process proceeds to step S5, and if not changed, the process proceeds to step S6.

  In step S5, the information display unit 2 changes the 3D display item according to the sheet position in response to the change of the sheet position in step S4. By changing the 3D display item, the information display unit 2 can display the 3D display item in the changed state when the changed 3D display item is displayed. The change of the 3D display item will be described with reference to FIG.

  In step S <b> 6, the information display unit 2 determines whether the 3D display item has been changed based on the operation signal from the input device 3. For example, the information display unit 2 determines whether or not any information among the images including a lot of information is changed to be a 3D display item or not to be a 3D display item. If the 3D display item has been changed, the process proceeds to step S7. If the 3D display item has not been changed, the process proceeds to step S8.

  In step S7, the information display unit 2 sets arbitrary information to the 3D display item or the 2D display item according to the change in step S6.

  In the next step S8, the information display unit 2 displays the 3D display items to be displayed on the 2D / 3D display display 1 in a normal two-dimensional display form (plane). In step S8, any of a menu image, various setting images, a running state image, and a map image, which will be described later, may be used.

  In the next step S9, the information display unit 2 determines whether or not a switch included in the input device 3 has been operated. If the switch has been operated, the process proceeds to step S10. If the switch has not been operated, the process proceeds to step S13.

  In step S10, when the operated item detected in step S9 is a 3D display item, the CPU 22 changes the display form of the display item to a three-dimensional display form, and performs the process in step S11. Proceed.

  In step S11, the CPU 22 determines whether or not the elapsed time after changing to the three-dimensional display form (stereoscopic display) in step S10 is equal to or longer than a certain time. If the elapsed time is equal to or longer than a certain time, the process proceeds to step S12. If not, step S11 is repeated.

  In step S12, the CPU 22 returns the stereoscopic display changed in step S10 to normal 2D (planar) display, and advances the process to step S17.

  In step S13, the information display unit 2 determines whether or not the displayed information has changed. If there is a change in the displayed information, the process proceeds to step S14, and if there is no change, the process ends. At this time, the CPU 22 includes the 3D display items currently displayed on the 2D / 3D display 1 among the information from the input device 3, the vehicle signal input unit 4, and the traffic jam information input unit 5 received by the interface 25. Judge whether it is. When the information regarding the 3D display item currently displayed on the 2D / 3D display 1 is changed, the process proceeds to step S14.

  In step S14, if the item whose change is detected in step S13 is a 3D display item, the CPU 22 changes the display form of the display item to a three-dimensional display form, and proceeds to step S15. .

  In step S15, the CPU 22 determines whether or not the elapsed time after changing to the three-dimensional display form (stereoscopic display) in step S14 is equal to or longer than a predetermined time. If the elapsed time is equal to or longer than a certain time, the process proceeds to step S16. If not, step S15 is repeated.

  In step S16, the CPU 22 returns the stereoscopic display changed in step S14 to normal 2D (planar) display, and proceeds to step S17.

  In step S <b> 17, the CPU 22 determines whether or not the ignition switch (IGN) remains ON based on the vehicle signal supplied from the vehicle signal input unit 4. If the ignition switch remains on, the process returns to step S4, and if not, the process ends.

  Next, the operation of the information display device that performs the above-described operation will be described with reference to a specific display example.

  In such an information display device, when the menu image 100 including a plurality of icons 101 and arrow buttons 102 as shown in FIG. 3A is displayed, the icons 101 or the arrow buttons 102 are operated. Then, the information display device changes the display form of the icon 101 to a three-dimensional display form. For example, when the “current location” icon 101 in FIG. 3A is operated, the icon 101 is a 3D display item, so that the information display unit 2 displays a three-dimensional display as shown in FIG. The display form is changed to the “current location” icon 101 ′ which is the form. After that, the information display unit 2 displays a map image 110 in a two-dimensional display form including a host vehicle icon 111 as a 2D / 3D display, as shown in FIG. 1 is displayed. This operation can be realized by performing the operations in steps S9 to S12 in FIG.

  Thereby, the information display device improves the visibility by changing only the icon that has been operated as information to be perceived into a three-dimensional display form, and shortens the recognition time of the operated information (icon). Can be made.

  As another example, the operation of FIG. 2 can also be applied to an air-conditioning state setting image 120 as shown in FIG. The setting image 120 includes a plurality of pieces of information such as air conditioner setting information in addition to the right driver's seat side set temperature information 121 and the left passenger seat side set temperature information 122. When the input device 3 is operated and the driver seat side set temperature is changed from 23 ° C. to 24 ° C., the information display unit 2 displays the driver seat side set temperature information 121 in a two-dimensional display form of 23 ° C. as shown in FIG. As shown in (b), it is changed to driver's seat side set temperature information 121 ′ in a three-dimensional display form at 24 ° C. After a certain period of time, the information display unit 2 returns the three-dimensional display form to the driver's seat side set temperature information 121 in the two-dimensional display form as shown in FIG. This operation can be realized by performing the operations in steps S9 to S12 in FIG.

  Thereby, the information display device improves the visibility by changing only the display item for which the setting change as the information to be perceived is changed to a three-dimensional display form, and shortens the recognition time of the changed information. Can be made.

  As yet another example, the operation of FIG. 2 can be applied to a running state image 130 as shown in FIG. The travel state image 130 includes shift information, travel distance information, and the like in addition to the fuel consumption information 131 of the bar graph. The fuel consumption information 131 represents the average fuel consumption in the travel history of the vehicle. The fuel efficiency information 131 is updated according to the traveling of the vehicle. When the average fuel consumption of the vehicle rises or falls, the information display unit 2 displays the fuel consumption information 131 in a two-dimensional display form, as shown in FIG. Change to '. The information display unit 2 returns the fuel consumption information 131 ′ in the three-dimensional display form to the fuel consumption information 131 in the two-dimensional display form as shown in FIG. This operation can be realized by performing the operations in steps S13 to S16 in FIG.

  Thereby, the information display device changes only the changed display information among the plurality of pieces of information displayed on the 2D / 3D display display 1 in the two-dimensional display form as information to be perceived to the three-dimensional display form. . Thereby, the visibility of information can be improved and the recognition time of the changed information can be shortened.

  As yet another example, the operation of FIG. 2 can be applied to a map image 110 as shown in FIG. The map image 110 includes a host vehicle icon 111, a road image, a place name image, and the like. When the traffic information that is not currently displayed is input from the traffic information input unit 5, the information display unit 2 performs display in a three-dimensional display form. Specifically, the information display unit 2 displays the traffic information 112 'as shown in FIG. 6B in a three-dimensional display form based on the road, the traveling direction, and the like included in the traffic information. The information display unit 2 changes the fuel consumption information 112 ′ in the three-dimensional display form to the traffic jam information 112 in the two-dimensional display form as shown in FIG. This operation can be realized by performing the operations in steps S13 to S16 in FIG.

  In this example, even if the information display device is information that is not displayed on the 2D / 3D display 1, if the information is changed, a three-dimensional display is displayed in the image of the two-dimensional display form. It can be displayed as form information. Therefore, according to this information display device, even information to be newly displayed can be displayed in a three-dimensional display form in a two-dimensional display form to improve visibility and shorten recognition time. it can.

  When presenting information on the road, only information on the road on the route recommended for the vehicle to travel can be displayed in a three-dimensional display form.

  As still another example, when displaying information in a three-dimensional display form, the information display unit 2 may change the type or degree of the three-dimensional display form in accordance with the traveling state. The type or degree of the three-dimensional display form is realized by steps S4 to S7.

  The information display unit 2 changes the type of the three-dimensional display mode so as to improve visibility according to the traveling speed of the vehicle, for example. Specifically, as shown in FIG. 7, when the traveling speed of the vehicle is low, a three-dimensional display form of fuel consumption information 131 ′ that floats on the front side of the 2D / 3D display 1 is used. The driver's focal position (the object to be seen) when the vehicle traveling speed is low tends to be close to the vehicle. For this reason, the 2D / 3D display 1 is set to a type of three-dimensional display in which the focal length from the viewpoint becomes short. On the other hand, the 2D / 3D display 1 displays fuel consumption information 131 ′ that forms a recess at the back of the 2D / 3D display 1 when the traveling speed of the vehicle is high. The driver's focal position tends to be far from the vehicle when the traveling speed of the vehicle is high. For this reason, the 2D / 3D display 1 is set to a type of three-dimensional display in which the focal length from the viewpoint is long. Thereby, the kind of three-dimensional display form can be changed according to a vehicle state, visibility can further be improved, and the recognition time of the information can be shortened. In particular, when the driver has a short focal distance, the changed information can be easily noticed. Further, when the driver's focal distance is long, the change in the focal distance from the far focal distance to the 3D display item that is the depth can be reduced, and the information to be visually recognized can be easily seen.

  The information display unit 2 may change the type of the three-dimensional display form according to the steering operation input from the vehicle signal input unit 4. For example, the traveling speed tends to be low while the steering is being operated, and the traveling speed tends to be high when the steering is not being operated. Therefore, the information display unit 2 displays the fuel consumption information 131 'in a three-dimensional display form as shown in FIG. 7A during the steering operation. On the other hand, the information display unit 2 displays the fuel consumption information 131 'in a three-dimensional display form as shown in FIG. 7B when the steering is not operated. Thereby, the kind of three-dimensional display form can be changed according to a vehicle state, visibility can further be improved, and the recognition time of the information can be shortened.

  Further, when changing the degree of the three-dimensional display mode, consider a running state image in which fuel consumption information is set as a 3D display item. When the seat position is changed to be close to the 2D / 3D display 1, the information display unit 2 has a three-dimensional display mode so as to reduce the 3D effect of the fuel consumption information 131 ′, as shown in FIG. Set the degree of. On the other hand, when the seat position is changed so as to be far away from the 2D / 3D display 1, the information display unit 2 is three-dimensional so as to increase the 3D effect of the fuel consumption information 131 ′ as shown in FIG. Sets the degree of display form. FIGS. 8A and 8B show fuel consumption information 131 ′ in which the fuel consumption information is displayed in 3D in the running state image. Comparing the fuel consumption information 131 'between FIGS. 8A and 8B, the depth and height are larger in FIG. 8B. As a result, the information display device can display the fuel efficiency information 131 ′ with enhanced 3D effect when the seat position is far from the 2D / 3D display 1.

  As described above in detail, according to the information display device shown as the present embodiment, the information to be recognized by the user is changed from the two-dimensional display form to the three-dimensional display form. A visual difference can be given between the information changed to the form and the information in the two-dimensional display form. Thereby, according to the information display device, the visibility of information to be perceived can be improved, and the recognition time can be shortened.

  Further, according to the information display device, in response to the change of the information displayed on the 2D / 3D display display 1, the changed information is changed from the two-dimensional display form to the three-dimensional display form. Can do. Thereby, according to the information display device, for example, the visibility of changed information such as the running state and traffic jam information can be improved, and the recognition time can be shortened.

  Furthermore, according to this information display device, the degree of the three-dimensional display form is adjusted according to the viewpoint position of the person viewing the information, so the distance from the analogy viewpoint position to the 2D / 3D display 1 varies. However, it is possible to effectively improve the visibility of information to be perceived and shorten the recognition time.

  Furthermore, according to this information display device, since the type of the three-dimensional display mode is adjusted according to the focal position of the person viewing the information, for example, even if the focal position of the user varies depending on the traveling speed, The visibility of information to be perceived can be effectively improved, and the recognition time can be shortened.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it is possible to change.
