Hereinafter, with reference to the drawings, embodiments of a content providing device, a content providing system, a content providing method, and a program according to the present invention will be described.

Figure 1 is a configuration diagram of a content provision system 1 that uses a content provision device according to an embodiment. The content provision system 1 is a system that provides content to passengers aboard a mobile object. The content is, for example, music. Music refers to music sung by an artist, performed by a musician, or played on a program, and may also include environmental sounds. In the following description, the content is assumed to be music, but the content may also include video content accompanied by images. Mobile objects include, for example, vehicles with a space where passengers can stay (four-wheeled or three-wheeled vehicles, micromobility, etc.), ships, aircraft, or motorcycles. In the case of a motorcycle, music may be played by an audio device installed in the helmet.

The content providing system 1 includes, for example, a music app 32 running on a mobile terminal device 10 and a front server 100. The front server 100 is an example of a content providing device. The mobile terminal device 10 and the audio device 50 are examples of devices used by a user.

[Mobile terminal device]
The mobile terminal device 10 is a portable computer device having communication functions, input/output functions, and application execution functions, such as a smartphone or tablet terminal. The mobile terminal device 10 includes, for example, a short-range communication unit 12, a network communication unit 14, a music application execution unit 16, and a touch panel 18.

The short-range communication unit 12 communicates with the short-range communication unit 60 of the audio device 50 wirelessly or via a wired connection based on communication standards such as Bluetooth (registered trademark), Wi-Fi, or USB (Universal Serial Bus).

The network communication unit 14 communicates with the front server 100 via the network NW. The network NW includes wireless base stations, access points, the Internet, provider terminals, WANs (Wide Area Networks), etc.

The music app execution unit 16 functions when a processor such as a CPU (Central Processing Unit) executes the music app 32 stored in the storage unit 30. The music app execution unit 16 controls each part of the mobile terminal device 10 in response to user input operations performed on the touch panel 18. The music app 32 is, for example, installed in advance on the mobile terminal device 10 from a server device of an app provider.

[Audio Device]
The audio device 50 is installed in a vehicle (or may be installed in a helmet, as described above). The audio device 50 includes, for example, an associated application execution unit 52, an acoustic adjustment unit 54, a speaker system 56, a touch panel 58, and a short-range communication unit 60.

The linked app execution unit 52 functions when a processor such as a CPU executes a linked app (not shown) stored in the storage unit. The linked app execution unit 52 controls each part of the audio device 50 in cooperation with the music app execution unit 16 in response to user input operations made on the touch panel 58.

The acoustic adjustment unit 54 controls the speaker system 56. The speaker system 56 includes, for example, multiple speakers. The acoustic adjustment unit 54 may adjust the volume of each of the multiple speakers to localize the sound image at any desired location.

As mentioned above, the short-range communication unit 60 communicates wirelessly or via a wired connection with the short-range communication unit 12 of the mobile terminal device 10.

[Front Server]
The front server 100 includes, for example, a network communication unit 102, a user information acquisition unit 104, a location information acquisition unit 106, a point of interest (POI) acquisition unit 108, a music data acquisition unit 110, a content providing unit 112, an image providing unit 114, and a storage unit 150. The components other than the network communication unit 102 and the storage unit 150 are realized by, for example, a hardware processor such as a CPU executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transitory storage medium) such as a hard disk drive (HDD) or flash memory, or may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or CD-ROM, and installed by inserting the storage medium into a drive device. The storage unit 150 stores information such as user information 152, map information 154, and required time information 156.

The network communication unit 102 communicates with the mobile terminal device 10 via the network NW. Note that communication between the front server 100 and the back server 200 may also be performed via the same network NW, but communication may also be performed via a dedicated line, LAN (Local Area Network), VPN (Virtual Private Network), etc.

The user information acquisition unit 104 acquires information about the user of the mobile terminal device 10 (user information) and registers it in the user information 152. Figure 2 is a diagram showing an example of the contents of the user information 152. The user information 152 includes, for example, name, age, gender, occupation, favorite music genre, favorite artists, hobbies, etc. The user information acquisition unit 104 updates the user information 152 as appropriate in response to input operations by the user or based on the music playback history.

The location information acquisition unit 106 acquires location information of the user (mobile body). The location information of the user (mobile body) may be determined by a positioning device (such as a GPS (Global Positioning System) receiver, not shown) provided in the mobile body on which the audio device 50 is installed and transmitted to the front server 100 via the audio device 50 and the mobile terminal device 10, or may be determined by a positioning device (not shown) provided in the mobile terminal device 10 and transmitted to the front server 100.

The POI acquisition unit 108 uses the user's location information to refer to map information 154 and acquires POIs within a song recommendation zone (hereinafter referred to as "recommended zones") within which the user has entered (hereinafter referred to as "POIs hit"). Entering a song recommendation zone is an example of approaching a POI (location). Figure 3 is a diagram showing an example of the contents of map information 154. Map information 154 includes multiple pieces of POI information and information on recommended zones corresponding to each of the multiple pieces of POI information. The POI information includes, for example, information such as the location information (latitude, longitude) of the POI and the type of POI associated with the POI (e.g., famous facilities, scenic spots, etc.).

The POIs included in the map information 154 may be changed as appropriate. For example, a POI that is hosting a time-limited event may be included in the map information 154 only during the period that the event is held. Furthermore, each piece of information associated with a POI may be changed as appropriate. For example, if a POI included in the map information 154 is holding an illumination event at a tourist spot, the recommendation area may be expanded only during the hours when the illumination event is held.

Map information 154 may further include information on road structure. If map information 154 includes road structure, the recommendation area may be set based on the distance traveled along the road to reach the POI. Note that POI included in map information 154 are considered to be targets for song recommendation, but map information 154 may also include POI that are not targets for song recommendation. In such cases, a flag indicating that the POI is a target for song recommendation is associated with the POI.

When a POI is found, the music data acquisition unit 110 sends a music request to the back server 200. The music request includes the user's user information (which may be processed to protect personal information, such as deleting the name, changing the age to "30s" or similar, and changing the occupation from detailed information to a more granular level such as "office worker") and POI information (which may be POI identification information) indicating the found POI. When multiple POIs are found, the music data acquisition unit 110 includes the POI information of one of the multiple POIs in the music request. The POI information to be included in the music request will be explained later.

As will be described later, when the back server 200 receives a song request, it automatically selects a song that matches the user and the POI, and acquires the song data of the selected song, for example in streaming format, from the song data 258 and sends it to the front server 100. The song data acquisition unit 110 acquires the song data sent by the back server 200 to be automatically recommended. The song data acquired by the song data acquisition unit 110 is automatically recommended based on the user's information and the POI information where the user falls within the recommendation range.

When the user enters the recommended area, the content provider 112 transmits the music data acquired by the music data acquisition unit 110 to the mobile terminal device 10, enabling the mobile terminal device 10 to play the music data. The mobile terminal device 10 then transmits the music data to the audio device 50, which plays the music data on the speaker system 56. Note that the function of storing the music data 258 and providing the music data may be located in the front server 100 or another server device.

The mobile terminal device 10 or audio device 50 suggests to the user that they play the recommended song because they are approaching a POI. For example, the mobile terminal device 10 or audio device 50 displays an image or outputs a sound asking the user whether they would like to play the suggested song, and if the user replies by touch operation or voice that they agree, the recommended song is played.

The function of the image provider 114 and the significance of the required time information 156 will be described later.

[Back Server]
The back server 200 includes, for example, a user characteristic information generation unit 202, a POI characteristic information generation unit 204, an automatic music selection unit 206, and a storage unit 250. Functional units other than the storage unit 250 are realized, for example, by a hardware processor such as a CPU executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or by a combination of software and hardware. The program may be stored in advance in a storage device such as an HDD or flash memory (a storage device with a non-transitory storage medium), or may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or CD-ROM, and installed by inserting the storage medium into a drive. The storage unit 250 stores information such as user characteristic information 252, POI characteristic information 254, a trained model 256, and music data 258.

The user characteristic information generation unit 202 generates user characteristic information in the form of vectors or the like based on the user information included in the song request. In preparation for second or subsequent song requests from the same user, the generated user characteristic information may be stored in the storage unit 250 as user characteristic information 252.

The POI feature information generation unit 204 generates POI feature information in the form of vectors, etc., based on the POI information included in the song request. In preparation for second or subsequent song requests related to the same POI, the generated POI feature information may be stored in the storage unit 250 as user feature information 252.

Note that one or both of the functions of generating user characteristic information from user information and generating POI characteristic information from POI characteristic information may be functions of the front server 100. In that case, a song request may include, for example, user characteristic information and POI characteristic information.

The automatic music selection unit 206 inputs user characteristic information and POI characteristic information corresponding to the music request into the trained model 256, and extracts music data from the music data 258 for music that matches the user and the POIs the user approaches and passes through, and automatically recommends the music. The automatic music selection unit 206 transmits the automatically recommended music data to the front server 100. The music data acquisition unit 110 of the front server 100 acquires the music data automatically recommended by the automatic music selection unit 206.

The trained model 256 is trained using information previously obtained from feedback experiment results as correct answer data. For example, when a "male in his 30s passes near Tokyo Tower," the trained model 256 is trained to select the song that was actually highly rated in that situation. The feedback experiment involves collecting user feedback, such as high ratings, low ratings, and replays, regarding songs provided through the Music app 32.

Figure 4 shows an overview of the processing flow for song recommendations. When the front server 100 acquires the user's location information transmitted by the mobile terminal device 10 or audio device 50, it references the acquired location information in map information to determine whether a POI has been found. If a POI has been found, the front server 100 includes the user information of the user who transmitted the location information and the POI information of the found POI in a song request and transmits it to the back server 200.

The back server 200 generates user characteristic information based on the user information corresponding to the transmitted song request and inputs it into the trained model 256. The back server 200 generates POI characteristic information based on the POI information corresponding to the transmitted song request and inputs it into the trained model 256. The back server 200 extracts the output data of the trained model 256 from the song data 258 as song data of songs that match the user and the POIs that the user approaches and passes through.

[Image provision function]
The image provision function of the image provision unit 114 will be described below. The image provision unit 114 provides the mobile terminal device 10 or the audio device 50 with an image (hereinafter, a content image) that is superimposed on a map image and indicates a location. For example, the image provision unit 114 has a route search function (or a function for requesting a route search from another device and acquiring a route), and provides, as a content image, an image that indicates a route from the user's location acquired by the location information acquisition unit 106 to a destination input into the mobile terminal device 10 or the like. FIG. 5 is a diagram showing an example of a content image IM1. As shown in the figure, the content image IM1 displays an image showing the user's location PU, the destination DT, the recommended route RP, and a POI (POI (1) in the figure) on the recommended route RP. The content image IM1 is updated in response to changes in the user's location PU. The content image IM1 may also display POIs (in the figure, POI(2), POI(3), and POI(4)) that are not on the recommended route RP but that will take a short time to reach the destination even if the recommended route RP is deviated from, and the additional time T ⁺ that would be required if a detour were made to the POI. The music application execution unit 16 displays the content image provided by the front server 100 on the touch panel 18. In the figure, the images representing the POIs are shown as text images, but the images representing the POIs may also be shown as icons, characters, or the like.

In content image IM1, the image provider 114 obtains the playback time of the content automatically recommended for a first POI (POI (1) in the figure) that the user passes through among multiple POIs, and determines the display mode of the second POI based on a comparison of the playback time of the content with the time required for the user to reach the second POI from the first POI. The second POI is, for example, a POI that is not on the recommended route RP. The required time is, for example, the time required to travel by vehicle, and is calculated based on traffic information obtained via a network, broadcast waves, etc.

For example, the image providing unit 114 acquires information on at least the playback time cT of a song recommended when the user arrives at POI (1) by requesting the song data acquiring unit 110 to query the back server 200 in advance. Then, the image providing unit 114 compares the required time _T12 from POI (1) to POI (2) with the playback time cT, the required time _T13 from POI (1) to POI (3) with the playback time cT, and the required time _T14 from POI (1) to POI (4) with the playback time cT. The image providing unit 114 displays a POI (an example of a first second location) whose required time is longer than the playback time cT in a more prominent manner than a POI (an example of a second second location) whose required time is shorter than the playback time cT on the mobile terminal device 10 or the audio device 50. A prominent manner refers to a high contrast with the surrounding image, high brightness, large size, etc. For example, image providing unit 114 displays, on mobile terminal device 10 or audio device 50, images relating to POIs whose required times are longer than playback time cT in a normal font, and images relating to POIs whose required times are shorter than playback time cT in an inconspicuous font, line, image, or the like such as gray. Alternatively, images relating to POIs whose required times are shorter than playback time cT may not be displayed on mobile terminal device 10 or audio device 50.

5, the time required _T12 to travel from POI (1) to POI (2) is shorter than the playback time cT, and the time required _T13 to travel from POI (1) to POI (3) and the time required _T14 to travel from POI (1) to POI (4) are longer than the playback time cT. Therefore, the image of POI (4) is displayed in a manner that makes it less noticeable than the images of POIs (2) and (3). In this way, the image providing unit 114 obtains the required times for multiple second POIs and determines the display manner for each of the multiple second POIs.

The second POI may include a POI on the recommended route RP. Fig. 6 is a diagram showing an example of a content image IM2 in which the second POI includes a POI on the recommended route RP. In the figure, POI (5) is on the recommended route RP and is a POI for which music recommendations are performed. However, since the required time _T15 from POI (1) to POI (5) is shorter than the playback time cT, the image of POI (5) is displayed in a less prominent manner than the image of POI (1).

The image providing unit 114 may also have a function to regenerate a route and display it on the mobile terminal device 10 or the audio device 50 based on an operation performed by the user on the mobile terminal device 10. In this case, the operation may be, for example, tapping on a POI that is not on the recommended route RP. At this time, the image providing unit 114 regenerates (reroutes) a route from the user's location acquired by the location information acquiring unit 106 to the destination entered in the mobile terminal device 10, using the tapped POI as a stopover. Determining the display mode of the second POI as described above may be performed only when the route is regenerated. FIG. 7 is a diagram showing an example of how the display mode of the second POI is changed in response to the user selecting a POI as a stopover. As shown in the figure, content image IM3 displays the original route, and content image IM4 displays the route after POI (6) is selected as a stopover. In the content image IM3, all POIs around the recommended route RP are displayed in the normal state, but in the content image IM4, the required time T ₆₇ from the newly selected POI (6) is displayed in an inconspicuous manner for POI (7) which is shorter than the playback time cT of the music played at POI (6), and the other POIs are displayed in the normal state.

To perform this processing, the image providing unit 114 may, for example, comprehensively calculate the required travel time between POIs within a predetermined distance and store this in the storage unit 150 as required travel time information 156. The image providing unit 114 may recalculate or reacquire the required travel time obtained from traffic information, for example, every predetermined time (e.g., 10 minutes to 1 hour), and update the required travel time information 156. Figure 8 is a diagram showing an example of the content of the required travel time information 156.

In the embodiment described above, the playback time cT is the time it takes to play a song from start to finish, but it is not limited to this and may be the time it takes to complete playback of the main part of the song, such as from the beginning to the chorus.

Furthermore, the method of acquiring music data is not limited to the above, and a system in which specific music is recommended for each POI may also be adopted. User characteristic information does not need to be referenced when selecting music data.

The functions of the image providing unit 114 described above may also be provided by the Music app 32. In this case, the image providing unit 114 of the front server 100 may provide the playback time cT of the song and the required time between POIs in response to a request from the mobile terminal device 10, and the Music app 32 may change the display mode of the second POI based on a comparison of these.

Furthermore, the terminal device used by the user may be an audio device 50 instead of a mobile terminal device 10. In other words, the above function may be realized by the audio device 50 communicating with the front server 100 without going through the mobile terminal device 10. Figure 9 is a configuration diagram of a content providing system 2 according to a modified example. In this case, the audio device 50 has the same function as the music app 32 in Figure 1, and the music app execution unit 70 uses the network communication unit 72 to display content images provided from the front server 100 on the touch panel 72.

In the embodiment described above, the front server 100 includes a location information acquisition unit 106 that acquires location information of the user; a content acquisition unit (108, 110) that references map information 154 containing information on multiple POIs and acquires content to be automatically recommended when the user's location information approaches one of the multiple POIs; a content provision unit 112 that transmits the acquired content to the terminal device (10, 50) used by the user to enable playback of the content; and an image provision unit 114 that provides the terminal device with a content image showing the POI by superimposing it on a map image, and that determines the display mode of the second POI based on a comparison between the playback time of content to be automatically recommended at a first POI among the multiple POIs that the user passes through and the time required for the user to reach the second POI from the first POI. This makes it possible to appropriately convey information about the location from which content is recommended to the user.

The above-described embodiment can be expressed as follows.

a processor connected to the storage medium;
The processor executes the computer-readable instructions to:
Acquiring location information of a user;
