  FIG. 4 is a flowchart illustrating an example of a control procedure executed by the control unit 401 of the host server 400.

  In FIG. 4, the processing shown in this flow is started by performing a predetermined start operation. First, at step SA10, the control unit 401 accesses the singing history database 4031 stored in the large-capacity storage device 403, and acquires singing history information (user ID, song ID, and singing date and time) of a plurality of users. At the same time, the music information database 4032 stored in the large-capacity storage device 403 is accessed to obtain music information (music ID, music title, and singer name) related to a plurality of music pieces.

  Thereafter, in step SA20, the control unit 401 generates map data that classifies the plurality of users for each singer name based on the singing history information of the plurality of users acquired in step SA10 and the music information regarding the plurality of songs. .

  As an example of the map data generation method, the control unit 401 first associates each singer name with each singing history information using the tune ID included in both the singing history information and the tune information as a key. Then, the plurality of singing history information each associated with the singer name is classified for each user with reference to the user ID included in the singing history information. Then, using a plurality of singing history information associated with each singer name and classified for each user, a feature vector having a plurality of singer names as components for each user (that is, a feature representing a singer's preference) Each vector). Thereafter, the plurality of feature vectors generated for each user are clustered according to these components, and the plurality of feature vectors are classified into a plurality of units arranged on a two-dimensional plane. Note that the clustering is a method of automatically classifying a plurality of data without an external standard using a clustering method such as a known K-means method or SOM (Self Organizing Map) method, or an algorithm thereof. is there. Then, in accordance with the classification result, each user is associated with a unit in which the corresponding feature vector is classified. At the same time, each singer name is plotted in association with the unit having the highest total number of singings by all the users who belong to the corresponding singer's music. As described above, map data is generated.

  That is, on the map data, a plurality of singer names have a predetermined singer similarity that increases as the plotted distance decreases, and decreases as the plotted distance increases. It is distributed in the distribution mode. Thus, users with similar singer preferences may share the same unit (in other words, the same singer name) or similar units arranged in close positions (in other words, similar singer with a close plotted distance). Singer name). Further, users having completely different singer preferences are classified into dissimilar units arranged in a distant position (in other words, dissimilar singer names with a long plotted distance).

  Then, the process proceeds to step SA30, and the control unit 401 uses the map data generated in step SA20 to determine a plurality of singer names distributed in the distribution manner as described above on the map data. According to the category, the classified map data (classification information) classified into a plurality of categories set in advance for the singer is generated.

  5 and 6 are explanatory diagrams conceptually showing an example of the data structure of the classified map data generated in step SA30. FIG. 6 corresponds to an enlarged view of a part A in FIG.

  5 and 6, in the classified map data, a plurality of (in this example, 100) units are plotted as hexagonal cells on a two-dimensional plane and arranged in a hexagonal lattice pattern. In addition, a plurality of singer names are plotted in a circular shape on a two-dimensional plane. The closer the plotted distance is, the higher the corresponding singer's similarity is. The farther the plotted distance is, the corresponding singer's similarity is. Are distributed in such a manner that the value becomes low. The plurality of singer names are classified into a plurality of categories (9 in this example).

  On this classified map data, each user is associated with any one of 100 units. Each singer name is associated with any one of the 100 units.

  Returning to FIG. 4, in step SA40 after that, the control unit 401, among the plurality of singer names included in the classified map data generated in step SA30, a specific plurality of singer names, in this example, nine. A total of 900 singer names that are the names of the top 100 singers with a high frequency of singing songs by a plurality of users in each of the categories are extracted. Then, array data (array information) in which the extracted 900 singer names are arranged in a predetermined array form corresponding to the distribution form on the classified map data is generated.

  Thereafter, in step SA50, the control unit 401 arranges the 900 singer names included in the array data generated in step SA40 in a 10 × 10 grid pattern for each category based on a predetermined algorithm. (Alignment information) is generated.

  FIG. 7 is an explanatory diagram for explaining an example of a method for generating alignment data. Here, in order to prevent the illustration and explanation from being complicated, among the 900 singer names included in the array data generated in step SA40, 9 singer names arranged in appropriate areas are represented by a 3 × 3 grid. An example of alignment in a shape is shown.

  As shown in FIG. 7A, first, an area including nine singer names is divided into three in the X-axis direction so that three singer names are included.

  Thereafter, as shown in FIG. 7B, the three divided areas divided into three in the X-axis direction are divided into three in the Y-axis direction so that one singer name is included for each divided area. Break down.

  Then, as shown in FIG. 7C, the size of each of the nine divided areas divided into three in the X-axis direction and divided into three in the Y-axis direction is made uniform, Each singer name is arranged so that the corresponding singer names are arranged. As a result, data in which the 9 singer names are arranged in a 3 × 3 grid is generated.

  By using the method as described above, it is possible to generate alignment data in which 900 singer names included in the array data are aligned in a 10 × 10 grid for each category.

  8 and 9 are explanatory diagrams conceptually showing an example of the data structure of the alignment data generated as described above.

  8 and 9, the alignment data has a data structure in which the 900 singer names are aligned in a 10 × 10 grid for each category. Note that one singer name is plotted on one grid in FIGS. 8 and 9. That is, a total of 900 grids in which 900 singer names are plotted one by one are classified into 9 areas with 10 × 10 grids corresponding to each category as one area (array area) as shown in FIG. ing. Further, as shown in FIG. 9, the 900 grids are classified into a total of 100 zones with a 3 × 3 grid as one zone (array small area).

  Returning to FIG. 4, in step SA60, the control unit 401 outputs the alignment data generated in step SA50 to the device main body 100 of each karaoke device 10 via the communication control unit 410 and the network NW. Thereafter, the processing shown in this flow is terminated. Note that the control unit 101 of the apparatus main body 100 outputs the alignment data input via the communication control unit 110 to the remote controller 200 via the communication control unit 110. The control unit 201 of the remote controller 200 stores the alignment data input via the communication control unit 210 in the storage device 203.

  FIG. 10 is a flowchart illustrating an example of a control procedure executed by the control unit 201 of the remote controller 200.

  In FIG. 10, the process shown in this flow is started when, for example, a user performs a use start operation of a predetermined music selection assist service for assisting music selection. First, in step SB5, the control unit 201 accesses the host server 400 (or another server on the side of the karaoke service providing company) via the communication control unit 210 and the network NW, and obtains information on the user who uses the music selection assist service. get. For example, the singer name associated with the unit into which the user is classified, the category name of the category into which the singer name is classified, the avatar image data corresponding to the user, and the like are acquired.

  Thereafter, in step SB10, the control unit 201 outputs a display signal to the display unit 202a and causes the display unit 202a to display a category selection screen D1 (see FIG. 11 described later). The procedure of step SB10 functions as the first display control means described in the claims.

  FIG. 11 is an explanatory diagram illustrating an example of the category selection screen D1 displayed in step SB10.

  In FIG. 11, the category selection screen D1 includes category names (in this example, “category 01”, “category 02”, “category 03”, “category 04”, “category 05”, “category”) that are the identifiers of the nine categories. Images P1, P2, P3, P4, P5, P6, P7, P8, and P9 including “06”, “Category 07”, “Category 08”, and “Category 09”). Of these images P1 to P9, an image including a category name of a category in which a singer name associated with a unit in which a user who is using the music selection assist service is classified (in this example, “category 05”). ”Includes an avatar image AP corresponding to the user in an overlapping manner. Thereby, the user can visually recognize to which category he belongs.

  Returning to FIG. 10, in the subsequent step SB20, in the state where the display unit 202a displays the category selection screen D1, the control unit 201 performs the touch panel unit 202b portion corresponding to any one of the images P1 to P9. By touching, it is determined whether or not a category selection operation for selecting a category corresponding to the image of the touched part has been performed. Until the user performs the category selection operation, the determination in step SB20 is not satisfied, and the process waits in a loop. When the user performs a category selection operation (when a user category selection operation is accepted), the determination in step SB20 is satisfied, and the process proceeds to step SB30. The procedure of this step SB30 functions as the first selection receiving means described in the claims.

  In step SB30, the control unit 201, among a plurality of singers belonging to the category (selected category) according to the category selection operation received in step SB20, a singer (first singer) having the highest frequency of singing music by a plurality of users. , The name of the first singer) is detected. Hereinafter, the singer detected in step S30 will be referred to as a “first singer” as appropriate.

  Then, the process proceeds to step SB40, and the control unit 201 reads the alignment data stored in the storage device 203. And the zone (specific arrangement | sequence small area) containing the said 1st singer's name is specified among the several zones contained in the area corresponding to the said category selection operation in the said alignment data.
