[0012] A map generation system having a map generation device and a map display device according to one embodiment will be described with reference to the drawings. Fig. 1 is a diagram illustrating a map generation system 10. The map generation system 10 has a map generation device 20 and a map display device 30.

[0013] The map generating device 20 generates a music playback map Mp that indicates which music is being played at which position. The configuration of the map generating device 20 will be described later. The music playback map Mp will be described in detail later using Figures 2A and 2B, etc. The map display device 30 has a communication module (not shown) and a display unit 30d. The map display device 30 is, for example, a smartphone, a tablet computer, a personal computer, etc. Both the map generating device 20 and the map display device 30 are connected to a communication network 40.

[0014] The map display device 30 displays the music playback map MP provided by the map generation device 20 on the display unit 30d via the communication network 40. This allows people involved in the music industry to view the music playback map MP. Note that general users may also view the music playback map MP.

[0015] Vehicle 50 is equipped with a position detection device 70, a communication device 72, and a music playback device 74. Figure 1 shows a state in which multiple vehicles 50 are moving at various locations. Position detection device 70 detects the position of vehicle 50 and the current time based on positioning signals from positioning satellites 90.

[0016] The vehicle 50 is also connected to the communication network 40 by the communication device 72. The communication device 72 may be a portable terminal brought into the vehicle 50. The music playback device 74 plays music. The music to be played by the music playback device 74 may be selected from music stored in the music playback device 74. The music to be played by the music playback device 74 may be selected from music that can be distributed from a music distribution server via the communication network 40 and the communication device 72. The music to be played by the music playback device 74 may be selected from music stored in a portable terminal in the vehicle 50.

[0017] Music information about the music played by the music playback device 74 is supplied to the map generation device 20 by the music playback device 74 via the communication device 72, together with location information indicating the location at which the music was played by the music playback device 74. Furthermore, time information indicating the time at which the music was played by the music playback device 74 is supplied to the map generation device 20 by the music playback device 74 via the communication device 72. The music information includes, for example, information about the title of the music and information about the musician of the music.

[0018] If a song includes lyrics, the musician of the song may be, for example, the singer, lyricist, performer, composer, etc. If a song does not include lyrics, the musician of the song may be, for example, the performer, composer, etc. The musician of the song may also be, for example, the producer of the song.

[0019] It is preferable that the music playback device 74 is provided on a mobile body and is mobile, rather than on a fixed structure such as a building. In this embodiment, the music playback device 74 is provided on the vehicle 50, but the music playback device 74 may be mounted on or constituted by another mobile body. An example in which the music playback device 74 is constituted by a mobile terminal will be described later with reference to FIG. 10.

[0020] The map generating device 20 includes a calculation unit 100, a storage unit 102, and a communication module 104. The calculation unit 100 is a computer and includes a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). That is, the calculation unit 100 includes processing circuitry.

[0021] The storage unit 102 is a computer-readable recording medium. The storage unit 102 includes a volatile memory such as a random access memory (RAM) and a non-volatile memory such as a read-only memory (ROM) or flash memory. The volatile memory is used as a working memory for the processor. The non-volatile memory stores programs executed by the processor, map data, etc. In other words, the map generating device 20 has a program product of the program executed by the processor.

[0022] By executing the program stored in the storage unit 102, a music playback map Mp is generated based on the above-mentioned music information and position information.

[0023] The communication module 104 is used for communication between the map generator 20 and the map display device 30 via the communication network 40. The communication module 104 is also used for communication between the map generator 20 and the vehicle 50 via the communication network 40.

[0024] The calculation unit 100 has an acquisition unit 110, a generation unit 112, and a provision unit 114. The acquisition unit 110, the generation unit 112, and the provision unit 114 are realized by the calculation unit 100 executing a program stored in the storage unit 102. At least some of the acquisition unit 110, the generation unit 112, and the provision unit 114 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array), or an electronic circuit including a discrete device.

[0025] The acquisition unit 110 acquires the above-mentioned music information, location information, and time information via the communication network 40 and the communication module 104.

[0026] The generation unit 112 generates a music playback map Mp based on the music information and location information acquired by the acquisition unit 110. When music information relating to multiple songs is acquired, the generation unit 112 generates a music playback map Mp for each song corresponding to each of the multiple songs. The generation unit 112 generates a music playback map Mp for each time further based on the time information acquired by the acquisition unit 110.

[0027] The providing unit 114 provides the music playback map Mp generated by the generating unit 112 to the map display device 30 via the communication module 104 and the communication network 40 .

[0028] The music play map Mp is generated by the generation unit 112 for each music piece and for each time period based on the music information, location information, and time information acquired by the acquisition unit 110. Therefore, it is possible to grasp the number of times a specific music piece is played at a specific time. Furthermore, by comparing the number of times the same music piece is played in the same area at different times, it is possible to grasp the change in the number of times the music piece is played over time.

[0029] 2A and 2B are diagrams showing an example of a music playback map Mp. The music playback map Mp shows where in a specific area a specific song is being played at a specific time. The music playback maps Mp shown in FIGS. 2A and 2B correspond to the same area and the same song, but at different times. The area in question is Japan. The song in question is "On the Sunny Side of the Street," and the musician of the song is Louis Armstrong.

[0030] 2A shows a music playback map Mp corresponding to the position where the music is being played by the music playback device 74 installed in the vehicle 50 as of 8:30 local time on December 17, 2021. The music playback map Mp is displayed on the display unit 30d of the map display device 30.

[0031] When the positions where the songs are being played are displayed, the positions may be crowded together, making the music playback map Mp difficult to see. Therefore, the music playback map Mp shown in FIG. 2A is color-coded according to the density of the positions where the songs are being played. This makes the music playback map Mp easier to see. The density of the positions where the songs are being played corresponds to the number of times the songs are being played. In other words, the music playback map Mp is color-coded according to the number of times the songs are being played.

[0032] In the example shown in FIG. 2A, area A1 in the music playback map Mp is displayed in green. This indicates that the music is being played in area A1. Area A2 in the music playback map Mp is displayed in yellow. This indicates that the number of times the music has been played in area A2 is greater than the number of times the music has been played in area A1. Area A3 in the music playback map Mp is displayed in red. This indicates that the number of times the music has been played in area A3 is greater than the number of times the music has been played in area A2.

[0033] In addition, areas in the music playback map Mp that are not area A1, area A2, or area A3 are not colored. The number of times a song has been played in an area that is not colored is even less than the number of times that song has been played in area A1, or is zero.

[0034] Fig. 2B shows a music playback map Mp corresponding to the position where the music is being played by the music playback device 74 installed in the vehicle 50 as of 8:30 local time on April 24, 2022. In other words, the time corresponding to the music playback map Mp shown in Fig. 2B is later than the time corresponding to the music playback map Mp shown in Fig. 2A. The music playback map Mp is displayed on the display unit 30d of the map display device 30.

[0035] As in Fig. 2A, the song playback map Mp shown in Fig. 2B is color-coded according to the number of times the song has been played. The song playback map Mp shown in Fig. 2B shows that the number of times the song has been played has decreased compared to the song playback map Mp shown in Fig. 2A. The number of times a song has been played corresponds to the popularity of the song. Therefore, it can be understood that the popularity of the song has decreased as a result of the decrease in the number of times the song has been played over time.

[0036] Fig. 3 is a flowchart showing an example of the operation of the map generating device 20. Fig. 3 shows the processing procedure of the map generating method by the map generating device 20. This processing procedure is performed by the calculation unit 100 of the map generating device 20 executing a program stored in the storage unit 102.

[0037] When this processing procedure starts, in step S1, the acquisition unit 110 acquires song information, location information, and time information via communication. In step S2, the generation unit 112 generates a song playback map Mp for each song and for each time based on the song information, location information, and time information acquired in step S1. In step S3, the provision unit 114 provides the song playback map Mp generated in step S2 to the map display device 30 via communication. When the processing of step S3 is completed, this processing procedure ends.

[0038] In this embodiment, the map generation device 20 acquires music information and location information regarding music played by a music playback device 74 provided in the vehicle 50. The map generation device 20 generates a music playback map Mp based on the acquired music information and location information. Therefore, it is possible to know which music is being played at which location inside the vehicle 50.

[0039] The above-described embodiment may be modified as follows: In the following modifications, explanations that overlap with the above-described embodiment will be omitted.

[0040] (Variation 1) In the above-described embodiment, a music playback map Mp is generated for each song, but this is not limiting. In this first modification, the music information acquired by the acquisition unit 110 from the music playback device 74 further includes information indicating the genre of the song. The generation unit 112 generates a music playback map Mp for each genre.

[0041] FIG. 4 is a diagram showing an example of the display of a music playback map Mp. The music playback map Mp is displayed on the display unit 30d of the map display device 30. The music playback map Mp shows where music of a specific genre is being played at a specific time in a specific region.

The music playback map MP shows where music of a specific genre is being played at a specific time in a specific region. FIG. 5 shows the locations in Japan where music containing the keyword "summer" in the lyrics or title is being played as of 16:00 local time on July 29, 2023. As exemplified in FIG. 5, the music playback map MP is displayed in a color-coded manner similar to FIGS. 2A and 2B. This allows users to grasp the number of times music related to a specific keyword is being played at a specific time and in a specific region.

[0044] (Variation 3) In the above-described embodiment, the music playback map Mp is displayed on the display unit 30d of the map display device 30, but this is not limiting. In this third modification, the music information acquired by the acquisition unit 110 from the music playback device 74 further includes information indicating the genre of the music.

[0045] 6 is a block diagram showing an example configuration of the map generating device 20. The calculation unit 100 further includes a search unit 116. Based on the song information, location information, and time information acquired by the acquisition unit 110, the search unit 116 searches, via the communication module 104 and the communication network 40, for activity schedule information regarding the activity schedule of musicians of the song indicated by the song information or the activity schedule of musicians related to the genre of the song.

[0046] The musician's activity schedule is composed of the venue and date and time of the event in which the musician will appear. The generation unit 112 superimposes the activity schedule information searched by the search unit 116 on the generated music playback map Mp. Since the activity schedule information is superimposed on the music playback map Mp, the convenience of the music playback map Mp is improved.

[0047] 7 is a diagram showing a display example in which musician activity schedule information F1 is superimposed on a music playback map Mp. As in FIG. 4, the display unit 30d of the map display device 30 displays a music playback map Mp that shows where in a specific area music of a specific genre is being played at a specific time. Furthermore, superimposed on the music playback map Mp is displayed activity schedule information F1 regarding the activity schedule of musicians related to that genre.

[0048] In the example shown in Figure 7, activity schedule information F1 indicating that a live event by jazz singer "Sato Ichiro" is scheduled to start at 19:00 on October 24, 2023 at Club Tokyo is displayed superimposed on a music playback map Mp showing the locations where jazz music is being played in Japan as of 19:30 local time on October 21, 2023.

[0049] 7, the activity schedule information F1 of musicians related to the genre of music indicated by the acquired music information is displayed on the display unit 30d of the map display device 30. However, this is not limiting. The activity schedule information F1 relating to the activity schedule of musicians of the music indicated by the acquired music information may also be displayed.

[0050] The search unit 116 searches for activity schedule information F1 related to an activity schedule within a predetermined period from the time corresponding to the music playback map Mp. By setting the predetermined period to, for example, about one week to one month, activity schedule information F1 related to an activity schedule in the relatively near future can be searched for. In the example shown in Fig. 7, information about a live event that will start at 19:00 on October 24, 2023, which is within one week from 19:30 on October 21, 2023, which is the time corresponding to the music playback map Mp, is superimposed on the music playback map Mp as activity schedule information F1.

[0051] Fig. 8 is a flowchart showing an example of the operation of the map generating device 20. Fig. 8 shows the processing procedure of the map generating method by the map generating device 20. This processing procedure is performed by the calculation unit 100 of the map generating device 20 executing a program stored in the storage unit 102. Steps that are the same as the steps described above with reference to Fig. 3 are given the same reference numerals, and explanations thereof will be omitted as appropriate.

[0052] When the processing of step S1 is completed, the process proceeds to step S21. In step S21, the search unit 116 searches, via communication, for activity schedule information F1 related to the activity schedule of the musician of the song or the activity schedule of musicians related to the genre of the song, based on the song information, location information, and time information acquired in step S1. When the processing of step S21 is completed, the process proceeds to step S2.

[0053] When the processing of step S2 is completed, the process proceeds to step S22. In step S22, the generation unit 112 superimposes the activity schedule information F1 searched for in step S21 on the music playback map Mp. When the processing of step S22 is completed, the process proceeds to step S3, and the music playback map Mp on which the activity schedule information F1 is superimposed is provided. When the processing of step S3 is completed, the process ends.

[0054] (Variation 4) In this fourth modification, the search unit 116 shown in Fig. 6 further searches for ranking information indicating a ranking of the number of times a song is played. The search unit 116 stores the searched ranking information in the storage unit 102 in association with the time information acquired by the acquisition unit 110. The generation unit 112 adds the ranking information searched by the search unit 116 to the generated song playback map Mp. Since the ranking information of the song is added to the song playback map Mp, the popularity of the song can be more clearly grasped.

[0055] The generation unit 112 further generates trend information relating to changes in the ranking of the number of times a song is played, based on the ranking information stored in the storage unit 102. The trend information indicates, for example, whether the ranking of a song is on an upward or downward trend. The generation unit 112 further adds the generated trend information to the generated song playback map Mp. Since the song trend information is added to the song playback map Mp, changes in the popularity of the song can be grasped.
