This singing game will be described in detail later.

  FIG. 4 is a diagram showing how user information is transmitted and received. A user who visits a karaoke store inputs identification information composed of his / her user ID and password, or causes the identification information stored in the IC card to be read by an IC card reader provided in the remote control device 1 or the like. The authentication process S101 is executed. The commander 2 or the remote control device 1 that has read the identification information of the user transmits the identification information to the karaoke host 5 (S102), and the karaoke host 5 that has received the identification information from the database stored in the storage unit 1, User information of the corresponding user is extracted (S121), and transmitted to the commander 2 or remote control device 1 that made the inquiry (S122).

  On the commander 2 side that has received the user information (S103), various service processes such as a music selection process and a performance process are provided based on the received user information (S104). When logout is requested by the user (S105), the service process is interrupted, and various histories (logs) during the service process or user information reflecting the setting change by the user is transmitted to the karaoke host 5 (S106). Here, as the user information, not only all the information but also the updated difference may be transmitted. The karaoke host 5 updates the database stored in the storage unit 1 based on the received user information (S124).

  The flow from one user authentication process (login) to logout has been described above, but the commander 2 and the remote control device 1 of this embodiment are in a state where a plurality of authenticated users (authenticated users) are logged in at the same time. By using the user interface described with reference to FIG. 2, it is possible to switch and use a user who provides a service (hereinafter referred to as “active user”).

  FIG. 5 is a diagram showing an active user top screen according to the embodiment of the present invention. As shown in this figure, when a plurality of people are logged in, the logged-in user column 103 displays the logged-in images 103a to 103e (face portions in this embodiment) of the logged-in user. In the login user column 103, the user whose background is highlighted at the right end is the active user 103e. In the state shown in the figure, the service for the active user 103e, that is, the user information of the active user 103e is used. The service is running.

On this active user top screen, by selecting “Search for a song”, a search based on a singer name and a song name can be performed as in the case of a conventional song book. In particular, in the present embodiment, by specifying “preference search”, it is possible to search for a song having a preference similar to the previously selected song by the active user. In addition, by designating a “singing game”, it is possible to play a country stealing game using this preference retrieval system.

  Then, two embodiment is described about the case where the singing information processing apparatus which concerns on this invention is applied to such a karaoke system. The present invention can also be provided as a program that can be executed on a karaoke system or various computers. First, an embodiment of “preference search” that can be selected from the active user top screen of FIG. 5 will be described.

  FIG. 6 is a flowchart showing the music selection process in this preference search. When “preference search” is selected for operation on the active user top screen of FIG. 5, the music reserved by the active user last time is acquired in S201. This music can be obtained by referring to a history table in the user information. Next, in S202, a category screen is displayed. In the present embodiment, a song having a preference similar to the previously reserved song acquired in S201 is selected as a recommended song. Further, in the selection, the recommended music is selected in consideration of the category designated by the user and the category item.

  FIG. 7 is a diagram showing this category designation screen. On this screen, the singer name (artist name), song name, and score (scoring information) are displayed for the previously reserved song acquired in S201. Furthermore, the user can specify a category and its category item. In this embodiment, the category and the category item can be selected from those preset by the pull-down menu. In the figure, “Region (Prefecture)” is selected as the category, and “Akita Prefecture” is selected as the category item. As described above, the category item can be selected from a plurality of category items corresponding to the selected category in a pull-down format. In addition, in addition to such regions (prefectures), various categories such as age (age), song age, constellation, blood type, etc. can be selected as appropriate for the category. For the user corresponding to the selected category and category item, a filtering process is performed on a classification diagram described later, and a recommended music is selected.

  In S203, categories and category items are received from the user, and when search execution is instructed (S204), filtering processing for the classification diagram is executed (S205). This classification diagram is created based on a history table acquired from a plurality of users who use the karaoke system, and is created by aggregation processing by the karaoke host 5 or the like. The commander 2 or the remote control device 1 receives this classification chart from the karaoke host 5 as occasion demands and uses it for the preference search.

  The classification diagrams according to this embodiment will be described with reference to FIGS. FIG. 9 is a diagram showing a classification diagram according to the embodiment of the present invention, and FIGS. 10 and 11 are diagrams for explaining music position determination in the classification diagram according to the embodiment of the present invention.

  FIG. 9 shows an overall view of the classification diagram 80 and an enlarged view of a part thereof. The classification diagram 80 includes a plurality of user classification cells 81 as shown in the figure. In this embodiment, 10 cells × 10 cells = 100 cells. A user who uses the karaoke system is classified so as to belong to any one of the user classification cells 81 based on the use history of music stored in the history table. At that time, the user's preference belonging to the adjacent user classification cell 81 is classified so as to be similar.

Specifically, it is executed by clustering a plurality of user history tables stored in the karaoke host 5 using a known appropriate method for each user. As an example of the method, a plurality of user history tables are classified for each user (user ID) corresponding to the history table. Then, using a plurality of user history tables classified for each user, a user feature vector for a plurality of music pieces, for example, a feature vector having a plurality of music identifiers as components, is generated for each user. Thereafter, using the initial values of the representative vectors of a plurality of user classification cells prepared in advance, a plurality of feature vectors generated for each user are obtained by a clustering technique such as a known K-means method or SOM method. Categorize in user classification cell. That is, the users are classified so that users whose feature vectors are short from each other, that is, users who sing or will sing similar music gather. Corresponding to the classification result, the history tables of a plurality of users are respectively associated with the user classification cells into which the feature vectors corresponding to the user IDs of the users are classified.

  The music that can be used in the karaoke system is positioned as a music icon 82 as shown in the enlarged view of the classification diagram. FIG. 10 shows how the position of each piece of music (music icon 82) is determined on the separation diagram. In the user classification cell 81, it is assumed that users with similar preferences belong based on the history table, but in the case of the music A used only by the user belonging to the user classification cell 81a, the music icon 82a It is assumed to be located at the center of the user classification cell 81a. On the other hand, when the music A is used in another user classification cell 81b, the music icon 82a of the music A is positioned so as to be pulled in the direction of the user classification cell 81b. As the number of uses of the user belonging to the user classification cell 81b increases, the user classification cell 81b is positioned closer. A music icon corresponding to one music identifier is determined at one position on the classification diagram. At this time, based on the number of times of use of the music corresponding to one music identifier of each user within a predetermined period, it is determined at any position on the user classification cell where the total number of usage of the users belonging to the user classification cell is the highest. The Rukoto.

  In FIG. 10, the music A is positioned so as to be pulled only by the user classification cell 81 b, but actually, the music icon 82 is positioned on the classification diagram by being pulled by the plurality of user classification cells 81. . FIG. 11 shows the music icon 81a of the music A used in the user classification cells 81b and 81c located symmetrically with respect to the user classification cell 81a of interest. When the number of uses in the user classification cells 81b and 81c is equal, the strength pulled from both is equal, and as a result, the music icon 82a is moved upward.

  The classification diagram of this embodiment has been described above. In this embodiment, the user's filtering process (S205) is executed for the category specified by the user and the category item for this classification diagram, and the recommended music is selected. You are going to choose. FIG. 12 is a diagram for explaining recommended music selection according to the embodiment of the present invention. FIG. 12A shows a classification diagram before the filtering process is executed, and FIG. 12B shows a classification diagram after the filtering process is executed. The filtering process is a process of extracting a specified category and music used by a user corresponding to the category item. As shown in FIG. 12B, as a result of the filtering process, some music icons 82 are excluded from the recommended music targets as indicated by broken lines.

Returning to the flowchart of FIG. 6, in S206, the recommended music is specified. In the present embodiment, on the classification diagram after the filtering process is performed, a song that is close in distance to the previously reserved song, that is, has a similar preference is selected. In FIG. 12B, the distance a between the music icon 82a of the previously reserved music A and the music icon 82 existing therearound is determined, and music B (distance a1) and music K (distance a2) are in order of increasing distance. ), Music H (distance a3)... Specified as recommended music.

  As described above, in the present embodiment, a song with a similar preference is selected for a song that the user has reserved, and a song with a preference close to a known song from a huge number of songs is recommended. Is done. In addition, because the category specified by the user and the music selected for the category item are recommended, it is recommended from the category that the user is interested in and the music that the user belonging to the category item has used. It becomes. Note that when karaoke is enjoyed by a plurality of users, the music reserved for a predetermined period after another user logs in may be excluded.

  In this embodiment, in S207, music already reserved in the period after the user logs in is excluded. With such a configuration, it is possible to avoid duplicate music reservations. The recommended music extracted by the above processing is displayed on the recommended music selection screen shown in FIG. 8, and music reservation can be accepted. In the present embodiment, a plurality of songs are displayed in the order similar in preference to the previously reserved song A, that is, in the order of the closest distance on the classification diagram after the filtering process, but the recommended song is one song. It doesn't matter.

  When the reservation is executed on the recommended music selection screen (S210), the music is stored in the reservation table managed by the commander 2, and is sequentially read and played by the acoustic control unit 70. After the performance is performed, various information is stored in the user's history table.

  As described above, in the preference search according to the present embodiment, by specifying a category and its category item, a song that is similar in preference to the previously reserved song is recommended. Not only the reserved music but also the user can select it appropriately. For example, arbitrarily selecting from songs stored in the history table, arbitrarily selecting from songs that can be used in the karaoke system, or selecting a song used under a predetermined condition It may be targeted. Further, although it is assumed that a plurality of categories can be selected, a configuration in which only one category item is selected by fixing to one category may be used.

  Next, an embodiment when the search system used in the preference search is used for a game will be described. This embodiment is a case where “singing game” is selected on the active user top screen of FIG. 5. The singing game of this embodiment is a country stealing game in which prefectures are acquired based on the singing scoring results, and the prefectures to be acquired are category items. Furthermore, the prefectures to be acquired can be selected only from the prefectures adjacent to the already acquired prefectures.

  When the process is started, first, one piece of music to be subjected to similarity determination is specified (S301 to S303). In S301, it is determined whether it is the first time in the singing game. This determination can be made by referring to the singing game table in the user information. If it is the first time for the user to perform a singing game (S301: Yes), one piece of music to be subjected to similarity determination is selected (S302). The selection of the music may be performed by the user himself / herself or on the apparatus side from the music located in the user classification cell to which the user belongs in the above-described classification diagram. In that case, it is good also as referring to the personal information of the user who performed the game, and selecting from the music filtered by the residence (prefecture).

In the present embodiment, music pieces that are similar in preference to one piece of music are sequentially selected, and thus the music used at the first time is preferably a music piece that is close to the user's taste. The music selection at the first time is not limited to this example. For example, the music may be selected from the music pre-registered by the user as the eighteenth, or the pre-registered artist (singer), or the music handled by the commander 2 It is good also as making a user choose from all.

  On the other hand, when it is determined that the singing game is executed for the second time or later (S301: No), the music is acquired when used in the previously executed singing game (S303). This musical piece may be a musical piece that has been successfully acquired by a prefecture, or may be a previously used musical piece regardless of whether or not the prefecture has been acquired. At the time of this game execution, a song that is similar in taste to this song is recommended as a task song for acquiring a prefecture. In S304, a category item designation screen for allowing the user to designate a prefecture to be acquired is displayed.

  FIG. 15 shows this category item designation screen. The category item designation screen is formed with reference to the singing game table in the user information. The singing game table stores the prefectures already acquired. On the category item designation screen, the already acquired prefecture is indicated by shading, and the avatar of the active user is displayed on the prefecture. In addition, the prefectures adjacent to the acquired prefectures are indicated by hatching as selectable acquisition candidates. The figure shows the category designation screen for user A, with Hokkaido, Aomori and Akita prefectures shaded as already acquired, and Iwate, Yamagata and Miyagi prefectures as shaded candidates for acquisition. Has been. In addition, at the first game that has not yet acquired a prefecture, the prefecture of the residence in the user's personal information can be a candidate for acquisition, or the neighboring prefecture can be acquired with the prefecture of the residence being acquired. It can be considered.

  In S305, selection of prefectures to be acquired as category items is accepted on the category item designation screen. FIG. 15 shows a state where Yamagata Prefecture is selected from the acquisition candidates. In S306, a filtering process is executed based on Yamagata Prefecture designated as a category item. That is, on the classification map, music extraction is executed for users who have Yamagata Prefecture as their residence. In S307, the music closest to the music acquired in S302 or S303 is specified as the recommended music on the filtered classification chart. At this time, as in the previous embodiment, it is also possible to specify the music piece closest to the distance after excluding the music piece designated by the user during a predetermined period after login. In S308, the music specified in S307 is displayed on the category designation screen, and the reservation of the music is awaited. In FIG. 15, the music name and singer name are displayed for the music piece as the subject song of Yamagata Prefecture. The user can reserve the music piece by operating a “reservation” button displayed on the screen.

  When the recommended music is reserved by such a series of processes (S309: Yes), it is managed in the reservation list of the commander 2 like the normal music, and the performance information corresponding to the music is sequentially played. Will be executed.

FIG. 14 is a flowchart showing music performance processing (game mode) according to the embodiment of the present invention. When the performance of the music described in the flowchart of FIG. 13 is started (S401), scoring processing is executed in synchronization with the performance (S402). This scoring process is a process of calculating scoring information by comparing the main melody included in the performance information with the pitch and volume of the singing voice signal input from the singing microphone 44. When the end of the performance is determined (S403: Yes), this scoring process is also ended (S404). In S405, as a result of the scoring process, it is determined whether the calculated scoring information is a predetermined score or more. If the score is equal to or higher than the predetermined score (S405: Yes), the prefecture (category item) and the like that are candidates for acquisition for the music are recorded in the singing game table (S406), and a display that informs the user of the acquisition is displayed. Execute (S407). On the other hand, when the predetermined score is not reached (S405: No), the display notifying that it could not be acquired is executed (S407) and the process is terminated.

  FIG. 16 is a diagram showing a result display screen displayed in S407, and is displayed on the monitor 41 on the commander 2 side in this embodiment. This figure is the result display screen that acquired Yamagata Prefecture specified on the category item specification screen of FIG. 15. The newly acquired Yamagata Prefecture is shaded and the score as a scoring result is also displayed. Has been.

  As described above, in the singing game to which the search system according to the present invention is applied, in the filtered classification diagram, music similar to one music can be set as the recommended music. Furthermore, scoring processing is performed for recommended music at the time of performance, and when the score exceeds a predetermined score, the category item is stored in the user information, so that it is possible to have a game characteristic of conquering multiple category items. ing.

  In the present embodiment, the country stealing game has been described in which the region (prefecture) is adopted as a category. However, the category is not limited to this form, and the game uses the various categories described in FIG. Is possible.
