<A. Embodiment 1>
<A-1. Configuration, operation>
FIG. 1 is a block diagram showing a configuration of a content providing apparatus 10 according to the present embodiment, and FIG. 2 is a schematic diagram during operation of the content providing apparatus 10.

The content providing device 10 is mounted on a vehicle 9 and includes a speaker 2 and a rear projection screen 4 as a content output unit, a head unit 1 that outputs content to the speaker 2 and the rear projection screen 4, and a power supply device 7 outside the vehicle. A power receiving unit 3 that receives power supply is provided. Note that the rear projection screen 4 is not required when outputting only audio content, and the speaker 2 is not required when outputting only video content. The rear projection screen 4 operates as a content display unit.

The head unit 1 holds or obtains content to be provided to the passenger from the outside, and in providing the content, the vehicle mechanism such as the suspension 5, the in-vehicle device such as the air conditioner 6, and the outside device such as the projector unit 8 It operates as a control unit that controls The content may be stored in a storage medium such as a CD, DVD, BD, or HDD, or may be received from the outside by communication.

The power receiving unit 3 is connected to the power supply device 7 outside the vehicle in a wired or wireless manner while the vehicle 9 is parked. The power supply device 7 is, for example, a charging stand installed in a parking lot, and supplies power to the power receiving unit 3. The power receiving unit 3 is connected to the head unit 1 via the in-vehicle LAN, and receives content and a control signal for the projector unit 8 from the head unit 1. The content and the control signal are transmitted from the power receiving unit 3 to the projector unit 8 via the power supply device 7.

The projector unit 8 is installed in the vicinity of a parked vehicle such as a parking lot, for example, and is connected to the power supply device 7 wirelessly or by wire as in the case of the power supply device 7. The projector unit 8 adjusts the attachment angle, the attachment position, the projection angle, and the like based on the control signal acquired from the power supply device 7, and performs alignment with the rear projection screen 4. Thereafter, the projector unit 8 projects the content onto the rear projection screen 4.

The rear projection screen 4 is installed on the front surface of the windshield of the vehicle 9, receives the projection light of the projector unit 8 on the rear surface, and displays an image on the front surface, so that the passenger can view the content. .

Next, the control operation of the head unit 1 will be described. The head unit 1 controls the vehicle mechanism or the in-vehicle device in conjunction with the content.

As an example of control of the vehicle mechanism, for example, the vehicle is vibrated up and down by adjusting the hardness of the suspension 5 in conjunction with the amount of screen movement of the video content (the amount of camera movement during shooting). By independently controlling the suspensions 5, the vehicle can be vibrated not only in the vertical direction but also in the horizontal direction. As a result, the passenger can feel the vibration linked with the video content and have a different experience from a normal movie theater.

In this way, when the vehicle is vibrated, a positional deviation occurs between the projector unit 8 fixed outside the vehicle and the rear projection screen 4 fixed to the vehicle. Therefore, the head unit 1 generates a control signal linked to the movement of the suspension 5 and transmits this to the projector unit 8 via the power receiving unit 3 and the power supply device 7. Since the projector unit 8 adjusts the projection position following the movement of the suspension 5 (controls the posture), even if the vehicle vibrates, there is no sense of incongruity that the image display surface is displaced from the rear projection screen 4.

As an example of control of the in-vehicle device, the air volume of the air conditioner 6 is adjusted based on the screen movement amount of the video content, for example, the air volume of the air conditioner 6 is increased in accordance with the content with fast camera work. It is also possible to adjust the temperature of the air conditioner 6 based on the color of the video content screen. For example, it is conceivable to increase the set temperature of the air conditioner 6 on a screen based on red, and lower the set temperature of the air conditioner 6 on a screen based on blue. In the case of audio content, the hardness of the suspension 5 and the air volume, air direction, and temperature of the air conditioner 6 may be changed in accordance with, for example, the low sound, based on the sound feature.

The air conditioner 6 and the suspension 5 are examples of control objects, such as a vehicle mechanism such as a wiper and a power seat, an in-vehicle device such as a room light and an ion generator that is not generally used for AV output, in other words, an in-vehicle device excluding the AV device. Can be controlled. As a result, it is possible not only to appeal to hearing and vision, but also to provide users with entertainment content with a sense of reality such as the theme park attractions.

The above control operation for the vehicle mechanism and on-vehicle equipment will be described with reference to the flowchart of FIG. First, when the head unit 1 acquires content (step S1), it determines whether or not control information is included in the content (step S2). Here, the control information is information that describes the control content of the control target. If the control information is included in the content in advance, the head unit 1 outputs the control information or a command corresponding thereto (hereinafter simply referred to as control information) to the in-vehicle LAN (step S4). The suspension 5 and the air conditioner 6 that have received the control information operate based on the control information, thereby realizing an operation linked to the content. When the control information is not included in the content (No in step S2), the head unit 1 analyzes the content of the content to generate control information (step S3), and outputs this to the in-vehicle LAN (step S4). . Specifically, as described above, information for controlling the hardness of the suspension 5, the air volume of the air conditioner 6, the wind direction, the set temperature, and the like is created based on the moving amount of the screen image, the hue, and the characteristic amount of the sound.

<A-2. Modification>
Although the projector unit 8 has been described as being provided outside the vehicle, it may be a component of the content providing apparatus 10 mounted on the vehicle, such as a head-up display unit. In this case, instead of projecting an image on the rear projection screen 4 provided on the front surface of the windshield, the video content is displayed by projecting a virtual image on the windshield itself as a projection screen. When the projector unit 8 is mounted on the vehicle 9, there is an advantage that it is not necessary to adjust the projection position of the projector unit 8 in conjunction with the position of the vehicle 9 and the control of the suspension 5.

Further, instead of using the projector unit 8 and the rear projection screen 4 to display the video content, the video content is displayed on a display 14 such as a liquid crystal display mounted on the vehicle 9 as in the content providing device 20 shown in FIG. It is good also as a structure.

Since the content providing apparatus 10 according to the first embodiment provides content in a state in which power is secured from the power supply apparatus 7, it is possible to provide the content for a long time even during parking. Further, it is possible to use the video content such as a movie by using the standby time at the time of charging. However, when the present invention is applied to an engine vehicle, the power supply unit 3 and the power supply device 7 are not necessary, so that the content providing device 30 shown in FIG. 5 is obtained. As a difference in configuration from the content providing device 10, a communication unit 13 is provided instead of the power receiving unit 3, and the communication unit 13 transmits a control signal and content to the projector unit 8 via a communication device 17 outside the vehicle. .

Similarly, when the content providing apparatus 20 is applied to an engine vehicle, the power supply unit 3 is not necessary, so that the content providing apparatus 40 shown in FIG. 6 is obtained.

It should be noted that the function of controlling each unit in conjunction with the contents may be performed by a device outside the vehicle such as the power supply device 7 (FIGS. 1 and 4) and the communication device 17 (FIG. 5) instead of the head unit 1. Thereby, the structure in the head unit 1 can be simplified.
