In addition, the wearable device 12 is provided with a battery (not shown), which can supply power to the camera unit 30, the display unit 32, and the sensor unit 34.

(Functional configuration of the transportation facility display device 10)
The traffic facility display device 10 realizes various functions using the above hardware resources. The functional configuration realized by the traffic facility display device 10 will be described with reference to FIG.

As shown in FIG. 2, the traffic facility display device 10 is configured to include, as functional components, a location information acquisition unit 40, a speed calculation unit 42, a user situation determination unit 44, a other user information acquisition unit 46, a traffic facility display unit 48, and an information display unit 50. Each functional component is realized by the CPU 20 reading and executing a program stored in the ROM 22 or storage 26.

The location information acquisition unit 40 acquires location information of the wearable device 12, which is a display device. Specifically, the location information acquisition unit 40 acquires location information based on a signal from the sensor unit 34 of the wearable device 12. Note that if it is clear that the user is a vehicle occupant, the location information of the wearable device 12 may be acquired indirectly based on a signal from a GPS (Global Positioning System) device mounted on the vehicle.

The speed calculation unit 42 calculates the speed of the user wearing the wearable device 12 based on the position information acquired at predetermined time intervals. The user status determination unit 44 determines whether the user is a pedestrian or a vehicle occupant from the user's speed calculated by the speed calculation unit 42. For example, the user status determination unit 44 may determine that the user is a pedestrian if the user's average speed in a predetermined time period is equal to or lower than a predetermined threshold. The user status determination unit 44 may also determine that the user is riding a two-wheeled vehicle such as a bicycle.

The other user information acquisition unit 46 acquires location information of other users around the user wearing the wearable device 12. Here, "other users" refers to users wearing a similar wearable device 12. For example, the other user information acquisition unit 46 may acquire location information of other users by receiving signals transmitted from a similar wearable device within a predetermined range centered on the position of the user wearing the wearable device 12.

The traffic facility display unit 48 displays on the display unit 32 traffic facility images relating to traffic facilities that are pre-stored in the storage 26 as a memory unit, so as to be superimposed in the user's line of sight. Here, the traffic facility display unit 48 displays traffic facility images that correspond to the user's current location information and direction. In addition, the traffic facility display unit 48 of this embodiment displays traffic facility images such as roads, traffic signals, signs, lanes, and guardrails, as an example.

The information display unit 50 displays other information that does not correspond to the traffic facility image on the display unit 32. Here, an example of the display contents displayed by the traffic facility display unit 48 and the information display unit 50 will be described with reference to Figures 3 and 4.

Figure 3 shows the front of the vehicle as seen from inside the vehicle cabin. As shown in Figure 3, vehicles V1, V2, and V3 traveling ahead can be seen from inside the vehicle cabin through the windshield glass 52.

A building H can be seen to the right front of the vehicle, and a tree T can be seen to the left front of the vehicle. In this embodiment, the road on which the vehicle is traveling is not well-maintained, and does not have any traffic facilities such as roads or traffic signals. In FIG. 3, reference numeral 54 denotes an instrument panel, and reference numeral 56 denotes a steering wheel.

As shown in FIG. 4, traffic facility images M1, M2, and M3 are displayed on the left display panel 32L (display unit 32) by the traffic facility display unit 48. In addition, a mark M4 that does not correspond to a traffic facility image is displayed on the left display panel 32L by the information display unit 50.

The traffic facility image M1 is an image that mimics a road, and is displayed superimposed on the scenery ahead of the vehicle. For this reason, the traffic facility image M1 is displayed in a virtual three-dimensional space so that the road appears narrower from the user's perspective in the distance than closer. The traffic facility image M1 also includes an image of a road that branches off to the left, allowing the user to make a left turn along this road.

The traffic facility image M2 is an image that imitates a traffic signal, and is displayed with its color changing based on a predetermined lighting pattern. Here, the lighting pattern of the traffic facility image M2 is displayed so that the color changes at the same timing as seen by surrounding users. In addition, as an example in this embodiment, the traffic facility image M2 is displayed in a floating state, but this is not limited to this, and it may be displayed as if it is standing on the ground like an actual traffic signal.

The traffic facility image M3 is an image that imitates a sign that displays a speed limit, and is an image that is displayed only when the user is a vehicle occupant. In this embodiment, as an example, the traffic facility image M3 is displayed in a floating state, but this is not limited to this, and it may be displayed as if it is standing on the ground like an actual sign. In addition, the traffic facility display unit 48 may display stop lines (not shown) and the like.

Mark M4 is superimposed on vehicle V1 and vehicle V3. Specifically, mark M4 is a mark for displaying the location information of other users in the vicinity, and in the state shown in FIG. 4, it can be seen that vehicle V1 and vehicle V3 are vehicles using similar wearable devices. On the other hand, since mark M4 is not displayed on vehicle V2, it can be seen that the occupant of vehicle V2 is not using a wearable device.

In this manner, the traffic facility display unit 48 displays traffic facility images M1, M2, and M3, and the information display unit 50 displays mark M4. The traffic facility display unit 48 also changes the display mode of the traffic facility images based on the location information of other users around the user.

Specifically, when there are no other users around the user, i.e., when vehicles V1 and V3 are not traveling in FIG. 4, the traffic facility display unit 48 changes the display mode of the traffic facility image. For example, the traffic facility display unit 48 may display the traffic facility image M1, which imitates a road, with a wider vehicle width. In addition, the traffic facility display unit 48 may display the traffic facility image M2, which imitates a traffic signal, in a color that allows constant progress.

Also, for example, in a situation where there are many other users around the user, the display mode may be changed to increase the number of lanes in the traffic facility image M1 that resembles a road.

Next, other examples of the display content displayed by the transportation facility display unit 48 and the information display unit 50 will be described with reference to FIG. 5.

As shown in FIG. 5, a building H and a tree T can be seen ahead of the user, who is a pedestrian wearing the wearable device 12.

Here, traffic facility images M5 and M6 are displayed on the left display panel 32L (display unit 32) by the traffic facility display unit 48. Also, a mark M7 that does not correspond to a traffic facility image is displayed on the left display panel 32L by the information display unit 50.

The traffic facility image M5 is an image that imitates a traffic signal, and is displayed with its color changing based on a predetermined lighting pattern. The lighting pattern of the traffic facility image M5 is also displayed so that the color changes at the same time as seen by surrounding users.

The traffic facility image M6 is an image that imitates a pedestrian crossing, and is an image that is displayed only when the user is a pedestrian. In other words, in this embodiment, the traffic facility display unit 48 changes the display mode of the image depending on whether the user is a pedestrian or a vehicle occupant.

Mark M7 is displayed on the right edge of the left display panel 32L and is an image of a vehicle pictogram and an arrow pointing to the right. Mark M7 is a mark to alert the user that a vehicle is approaching from the right side.

(Action)
Next, the operation of this embodiment will be described.

(Transportation facility display processing)
An example of a traffic facility display process by the traffic facility display device 10 will be described with reference to the flowchart shown in Fig. 6. This display process is executed by the CPU 20 reading out a display program from the ROM 22 or the storage 26, expanding it in the RAM 24, and executing it.

The CPU 20 acquires location information in step S102. Specifically, the CPU 20 acquires the user's location information directly or indirectly through the function of the location information acquisition unit 40.

The CPU 20 calculates the speed in step S104. Specifically, the CPU 20 calculates the average speed of the user using the function of the speed calculation unit 42.

In step S106, the CPU 20 determines whether the user is a pedestrian. Specifically, if the average speed is equal to or less than a predetermined threshold value due to the function of the user status determination unit 44, the CPU 20 determines that the user is a pedestrian and proceeds to the process of step S108.

The CPU 20 displays an image in step S108. Specifically, the CPU 20 uses the function of the traffic facility display unit 48 to display a traffic facility image corresponding to the user's current location on the display unit 32 of the wearable device 12. At this time, the image displayed on the display unit 32 is only the image displayed to pedestrians, and no image is displayed to vehicle occupants. The CPU 20 also uses the function of the information display unit 50 to display other marks that do not correspond to the traffic facility image on the display unit 32 of the wearable device 12. Then, the CPU 20 ends the traffic facility display process.

On the other hand, if the CPU 20 determines in step S106 that the user is not a pedestrian, the process proceeds to step S110. The CPU 20 displays an image in step S110. Specifically, the CPU 20 uses the function of the traffic facility display unit 48 to display a traffic facility image corresponding to the user's current location on the display unit 32 of the wearable device 12. At this time, the image displayed on the display unit 32 is only the image displayed to the vehicle occupants, and no image for pedestrians is displayed. The CPU 20 also uses the function of the information display unit 50 to display other marks that do not correspond to traffic facility images on the display unit 32 of the wearable device 12. Then, the CPU 20 ends the traffic facility display process.

As described above, in the traffic facility display device 10 according to this embodiment, the traffic facility image corresponding to the position information of the wearable device 12 is displayed on the display unit 32 so as to overlap with the user's line of sight. This makes it possible to build a traffic system even in areas where roads, traffic signals, etc. are insufficiently developed.

In addition, in this embodiment, when a user is driving a vehicle and there are many users around, congestion can be avoided by changing the display mode to increase the number of lanes on the road. Conversely, when there are no users around, convenience can be improved by changing the display mode to change the display of traffic lights so that the user does not have to stop.

Furthermore, in this embodiment, when the user is a pedestrian, as shown in FIG. 5, information about approaching vehicles and pedestrian crossings are displayed, while signs necessary only for the vehicle driver are hidden, thereby reducing annoyance. On the other hand, when the user is a vehicle passenger, as shown in FIG. 4, signs indicating speed limits are displayed, allowing the vehicle to travel safely.

Furthermore, in this embodiment, by looking at the mark M4, the user can grasp the location information of other users, and can indirectly recognize non-users who are not using the traffic facility display device 10. This allows the user to act with consideration for non-users who cannot see the traffic facility image. For example, vehicle V2 in FIG. 4 is a non-user who cannot see the traffic facility image, so even if the traffic signal is emitting a color indicating a stop, it can be determined that vehicle V2 is highly likely to proceed. On the other hand, since other vehicles are traveling in a queue, the occupants of vehicle V2 can follow the other vehicles and drive in an orderly manner, even though they are non-users who are not using the traffic facility display device 10.

In addition, in this embodiment, the wearable device 12 that can be worn on the head of the occupant is used as a display device, so that the traffic facility image can be displayed by following the line of sight of the occupant. Furthermore, even if the user gets off the vehicle and is walking, by keeping the wearable device 12 attached, the traffic facility image can be viewed without performing any special operations.

Second Embodiment
Next, a transportation facility display system S2 according to a second embodiment will be described with reference to the drawings. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

As shown in FIG. 7, the traffic facility display system S2 of this embodiment includes a traffic facility display device 10 similar to that of the first embodiment. Here, the traffic facility display device 10 is electrically connected to a forward camera 62 and a display device 64.

The forward camera 62 is mounted on the vehicle and is a camera that captures an image in front of the vehicle. The display device 64 is mounted on the vehicle and includes a display unit located in front of the driver's seat, and is a device that displays content such as images and text using AR technology. For example, the display device 64 may be a head-up display device that projects an image onto the windshield glass 52. Also, for example, the display device 64 may be a transparent display device equipped with a dimming unit inside the windshield glass.

As shown in FIG. 8, the windshield glass 52 is provided with a display unit 66 on which a traffic facility image is displayed by a display device 64. For ease of explanation, the boundary of the display unit 66 is drawn, but in reality, the display unit 66 is transparent, so the boundary is not visible.

Traffic facility images M1, M2, and M3 are displayed on the display unit 66, as in the first embodiment. In addition, a mark M4 is displayed above the vehicles V1 and V3. The traffic facility images M1, M2, and M3 are displayed by the function of the traffic facility display unit 48, and the mark M4 is displayed by the function of the information display unit 50.

(Action)
Next, the operation of this embodiment will be described.

In this embodiment, the display unit 66 of the display device 64 is disposed in the front of the vehicle interior, including the driver's seat, so that images of traffic facilities in front of the vehicle can be viewed without wearing a dedicated device such as a wearable device. Other functions are the same as those of the first embodiment.

The above describes the traffic facility display systems S1 and S2 according to the first and second embodiments, but it goes without saying that the present invention can be embodied in various forms without departing from the spirit of the present invention. For example, in the above embodiment, a traffic facility image resembling a traffic signal is displayed in a location where there is no traffic signal, but the present invention is not limited to this. That is, an image may be superimposed on a broken traffic signal. Specifically, the operation status of the traffic signal may be acquired, and if there is a traffic signal that is not working, the image of the traffic signal may be superimposed on the position of the traffic signal. This makes it possible to maintain the traffic system even in a situation where the traffic signals are not functioning due to a power outage or the like.

In the above embodiment, as shown in FIG. 4, the mark M4 indicating other surrounding users is described, but the present invention is not limited to this. For example, the position information of non-users who are not equipped with a traffic facility display device 10 and are present around the user may be displayed. That is, in FIG. 4, a mark similar to the mark M4 may be placed on the vehicle V2, which is a non-user. In this case, compared to the case where a mark is placed on the user, the user can intuitively grasp which vehicles to watch out for.

In addition, in the above embodiment, the information display unit 50 displays images that do not correspond to traffic facility images as marks M4 and M7, but other images may be displayed. For example, the information display unit 50 may display disaster information, etc. on the display unit 32 in the event of a disaster.
