Description

  The present disclosure relates to an event management server and a program for providing a participation type event in which a user in a karaoke apparatus achieves a goal.

  In the karaoke apparatus, there is known a karaoke apparatus equipped with a function for providing enjoyment of competing for a singing score with other users by using a scoring application for scoring a user's singing technique. For example, Patent Document 1 describes a karaoke system that allows a team to compete in a karaoke song scoring result among a plurality of teams. In addition, a service is provided that ranks singing scores of customers nationwide in real time and gives a privilege to the users according to the ranking results. Thus, the device which raises the customer's willingness to visit a karaoke store is made by providing various ways of enjoying to the customer.

JP 2003-255964 A

  By the way, in order to increase the willingness of customers to visit the karaoke store and promote the use of the karaoke service, it is conceivable to hold a participatory event that grants a privilege according to the use performance of the karaoke service. For example, a privilege is given on condition that a specific task music is set and the evaluation of a scoring result or the like for a user who sang the task music satisfies a standard.

  By holding such a participatory event, it is possible to increase the appeal to users, and to expect an increase in revenue due to an increase in the number of users and improvement in the utilization rate of the karaoke service. In such a participatory event, the administrator must select specific issues to be reviewed and target conditions to be achieved by users in order to maintain a uniform standard for judging the achievement of the target conditions. Operation such as setting arbitrarily is conceivable.

  However, when a specific song is set as a task song, the task song is a song that is easy to sing for one user, but is not easy to sing for another user. In addition, there is a case where the affinity with the subject music is different among users. In addition, the following can be considered as an element for measuring the affinity (that is, good compatibility) between the subject song and the user. For example, the gender mismatch between the original artist of the music and the user, the mismatch between the sound range that the user can produce and the sound range of the music, whether or not the music is acceptable to the user.

  It seems that it is difficult to achieve the target condition for users who have low affinity with the theme song. Such a customer has a high possibility of not being able to achieve the target condition even if he / she participates, so it becomes difficult to improve his / her motivation for the participation type event. As a result, there is a risk that it will not be possible to expect an increase in the number of users due to participatory events and an improvement in the operating rate of the karaoke service.

  Therefore, in order to improve the user's willingness to participate in a participatory event, it is important to appropriately set a subject song that is a target of the participatory event. However, there is a problem that it is burdensome for an administrator to accurately grasp the customer base that changes from time to time and to set appropriate task music flexibly.

  Therefore, the present disclosure provides a technique for flexibly setting a subject song for a participation type event in which a user of a karaoke apparatus achieves a target condition.

  The event management server which concerns on 1 aspect of this indication is comprised so that the user of at least 1 karaoke apparatus may manage the participation type event which achieves target conditions. The event management server includes an attribute information acquisition unit, a candidate determination unit, a task song determination unit, a notification unit, and a difficulty level determination unit.

  The attribute information acquisition unit is configured to acquire attribute information that is information representing at least one attribute of the customer. The candidate determination unit is configured to determine a candidate for a song that is a song to be sung by a user in a participation type event from a plurality of given karaoke songs. Specifically, the candidate determination unit is classified according to the content of the matching attribute from among a plurality of karaoke songs that match the attribute of the customer represented by the attribute information acquired by the attribute information acquisition unit. The candidate song is determined for each level of difficulty.

  The assignment song determination unit selects a assignment song candidate from among the candidates of the assignment songs at multiple levels of difficulty determined by the candidate decision unit according to the progress of the holding period, which is a period during which the participation event is held. It is comprised so that the subject music to apply may be determined. The notifying unit is configured to notify the karaoke apparatus of information representing the task song determined by the task song determining unit. The evaluation information acquisition unit is configured to acquire evaluation information, which is information indicating evaluation of singing when the user sings the task song, from the karaoke apparatus notified of the task song by the notification unit.

  The achievement determination unit is configured to determine whether or not a target condition that is an evaluation condition to be achieved by the customer in the participation type event is achieved based on the evaluation information acquired by the evaluation information acquisition unit. Yes. The difficulty level determination unit determines whether or not the evaluation of the user's song has reached a determination reference value at a predetermined timing in the holding period under a condition in which the target condition is determined not to be achieved by the achievement determination unit. It is configured to judge. The determination reference value is a reference for determining whether or not to change the difficulty level of the subject song.

  In addition, the task song determination unit determines the candidate corresponding to the highest difficulty among the candidate song candidates for each level of difficulty as the task song corresponding to the first stage of the holding period. It is configured. Furthermore, when the difficulty determination unit determines that the evaluation of the user's singing has not reached the determination reference value, the task song determination unit determines whether the task song determination unit has a previous problem song candidate for each level of difficulty. A candidate corresponding to a difficulty level lower than the difficulty level is determined as a task song. Furthermore, the notification unit is configured to notify the karaoke apparatus of information indicating the newly determined task song when the new task song is determined by the task song determining unit.

  In the present disclosure, the music selected by the event management server from the karaoke music that matches the user's attributes is the subject music that the user should sing in the participation type event. According to the event management server configured as described above, the task music corresponding to the difficulty level in a plurality of stages classified according to the content of the suitable attribute is set from among the karaoke music suitable for the user attribute. can do. If it is a participatory event that has a theme song that matches the attributes of the user, it is expected that users will actively participate in the participatory event, and profits will increase due to an increase in the number of users and improvement in the utilization rate of karaoke services Can contribute to the improvement. In addition, such a flexible event can be automatically created, thereby reducing the burden on the administrator.

  Furthermore, if the target condition is not achieved during the participatory event period and the evaluation of the singing does not meet the criteria, the task song is less difficult as the participatory event period elapses Can be changed. In this way, even if it was difficult to achieve the target condition in the original task song, the customer achieved the target condition by replacing the task song with a less difficult one depending on the situation. It becomes easy. Thereby, a user's willingness to participate can be raised and a staying time can be improved, without making a user give up on the way.

  In the above configuration, the following may be further performed. That is, the attribute information acquisition unit is information that is registered in advance as music that the user is interested in as attribute information of the user, and information that represents a sound range (that is, a pitch range) that the user can sing. The information includes at least one of information representing the age of the user, information representing the gender of the user, and information representing the number of times the user sang a specific song.

  Music that the customer is interested in (for example, the so-called eighteenth song that the customer is good at), songs that have been sung a lot, and songs that are related to the user's age group are used for songs. It is considered suitable as a task song that has a deep understanding of customers and is easy to sing by customers. In addition, if the range and gender that the user can sing match with the range that composes the song and the gender of the original artist, the song is considered suitable as a subject song that is easy for the user to sing. . Therefore, by determining the task music based on the attributes of the user as described above, it is possible to present a task music with good compatibility that is easy to sing by the user.

  In the above configuration, the following may be further performed. That is, the difficulty level determination unit determines whether or not the evaluation of the singing of the user reaches the determination reference value set individually for each of the plurality of timings at each of the plurality of timings in the holding period. It is configured. Further, the determination reference value is set so that it is lower as the timing is earlier and higher as the timing is later.

  According to such a configuration, the difficulty level of the subject song is unlikely to decrease at an early stage of the holding period, and the difficulty level of the subject song tends to decrease as the remaining time of the holding time decreases. As a result, it is possible to have the challenge song with as high a difficulty as possible, unless the difficulty level of the issue song is excessively high at the beginning of the holding period. By doing so, the participatory event can be rewarding for the user. On the other hand, since the target condition becomes easier to achieve as the remaining time of the holding time decreases, it is possible to prevent the user from giving up until the end.

  In the above configuration, the following may be further performed. That is, the attribute information acquisition unit is configured to obtain, as the user attribute information, information registered in advance as music that the user is interested in, information indicating a range in which the user can sing, and the age of the user. Information that includes at least the information to be represented is acquired.

  The candidate determination unit has a high degree of difficulty for music composed of a sound range that matches a sound range that the user can sing and is associated with an age group including the age of the user. The assignment is determined as a candidate song corresponding to the first difficulty level. In addition, a musical piece that is composed of a musical range that matches a musical range that can be sung by the user, and that is interested in the user, a subject musical piece that corresponds to the second difficulty level, which is a low level of difficulty. As a candidate.

  The task song determination unit determines a candidate corresponding to the first difficulty level as a task song as the task song corresponding to the first stage of the holding period. Then, when the difficulty level determination unit determines that the evaluation of the user's singing has not reached the determination reference value, the candidate corresponding to the second difficulty level is determined as the task song.

  According to such a configuration, on the premise that the music is composed of a sound range that matches the sound range that the user can sing, the music that is associated with the same age group as the user has a high degree of difficulty. It is possible to set a song that is of interest to the user as a task song and a task song with a low difficulty level. This is based on the viewpoint that the music suitable for the user's age group has good compatibility with the user, but the music that the user is interested in is more compatible with the user.

  Or you may comprise as follows. That is, the attribute information acquisition unit includes, as user attribute information, information registered in advance as music that the user is interested in, the number of times the user sang music that the user is interested in, and the user singing It is configured to acquire information including at least the sound range that can be played and the age of the user.

  The candidate determination unit is a song composed of a range that matches the range that the user can sing, and given the number of times it has been sung by people in the age group including the age of the user. The music corresponding to the lower rank in the ranking is determined as a candidate song candidate corresponding to the first difficulty level, which is the highest difficulty level. In addition, music that is composed of a sound range that matches a sound range that can be sung by a user and that is relatively higher in the ranking is assigned to the second difficulty level that is the second highest difficulty level. Decide as a candidate for the corresponding assignment.

  In addition, a song that is composed of a range that matches the range that can be sung by the user and that has a relatively low frequency of singing among the songs that the user is interested in is the third As a candidate for the subject song corresponding to the third difficulty level, which is a high difficulty level. In addition, the music that is composed of a sound range that matches the sound range that can be sung by the user and that has a relatively high frequency of singing among the music that the user is interested in is the lowest. It is determined as a candidate for the subject song corresponding to the fourth difficulty level, which is the difficulty level.

  The difficulty level determination unit evaluates the singing of the user in the order of the predetermined first timing, second timing, and third timing under the condition that the target condition is determined not to be achieved by the achievement determination unit. Is configured to determine whether or not the determination reference value has been reached.

  The task song determination unit determines a candidate corresponding to the first difficulty level as a task song as the task song corresponding to the first stage of the holding period. Furthermore, when the difficulty level determination unit determines that the evaluation of the user's singing has not reached the determination reference value at the first timing, the candidate corresponding to the second difficulty level is determined as the task music. Alternatively, when the difficulty level determination unit determines that the evaluation of the user's singing has not reached the determination reference value at the second timing, the candidate corresponding to the third difficulty level is determined as the task song. Alternatively, when the difficulty level determination unit determines that the evaluation of the user's singing has not reached the determination reference value at the third timing, the candidate corresponding to the fourth difficulty level is determined as the task song.

  According to such a configuration, on the premise that the music is composed of a sound range that matches the sound range that the user can sing, the music that is associated with the same age group as the user has a high degree of difficulty. It is possible to set a song that is of interest to the user as a task song and a task song with a low difficulty level. This is based on the viewpoint that the music suitable for the user's age group is compatible with the user, but the music that the user is interested in is more compatible with the user. In addition, based on the viewpoint that the more frequently sung songs are, the deeper the user's understanding is, the less frequently sung songs are set as difficult task songs, and the more frequently sung songs are difficult. It can be set as a low-priority assignment.

  The present disclosure can also be realized in the form of a program executed on a computer or a storage medium storing the program.

<First Embodiment>
Hereinafter, a first embodiment of processing executed by the event management server 10 regarding a participation type event will be described.

<< Explanation of event processing >>
The procedure of event processing (first embodiment) executed by the control unit 11 of the event management server 10 will be described with reference to the flowchart of FIG. This process is executed at a predetermined timing (for example, a timing designated by the administrator) in the business period of the karaoke store where the event management server 10 is installed.

  In S100, the control part 11 acquires the attribute information of the user who is logging in to each karaoke apparatus 20 at the present time. Specifically, the control unit 11 makes an inquiry to each karaoke device 20 to identify a logged-in user, and requests the center server 30 to acquire attribute information corresponding to the identified customer identification information. The center server 30 reads out attribute information regarding the customer corresponding to the request from the event management server 10 from the database, and transmits it to the event management server 10 that is the request source. The user attribute information includes the above-described customer information and music use history information. Or the control part 11 may acquire directly the attribute information which each karaoke apparatus 20 acquires from the center server 30 and holds from each karaoke apparatus 20. FIG.

  In S <b> 102, the control unit 11 corresponds to the “first difficulty level” based on the age of the user indicated by the attribute information acquired in S <b> 100 and the national ranking for each age group distributed from the center server 30. Identify the candidate songs. The “first difficulty level” corresponds to a relatively high difficulty level in the first embodiment. Specifically, the control unit 11 selects a music that matches the user's range from the music included in the national ranking corresponding to the user's age group (hereinafter referred to as the age-specific ranking music). Identifies candidate songs for “Difficulty”. The music that matches the user's sound range here is a music composed of sounds in which the melody of the singing part is included in the range of the user's sound range.

  For example, the control unit 11 compares information representing the sound range constituting the singing part of the ranking song by age and the user's sound range, and determines whether or not the age-ranked song matches the user's sound range. . If there is no age-ranked music that matches the user's range, the user's gender indicated by the attribute information is compared with the gender of the artist of the age-ranked music, and the matching music is identified as “first difficulty level”. ”May be specified as a candidate song candidate. Alternatively, if there is no age-ranking song that matches the user's range, specify the key settings for adjusting the age-ranked song key to match the user's range, and then rank the song and key settings by age And may be specified as a candidate song candidate of “first difficulty level”.

  In S <b> 104, the control unit 11 identifies a candidate song candidate corresponding to the “second difficulty level” based on the attribute information acquired in S <b> 100. The “second difficulty level” corresponds to a relatively low difficulty level in the first embodiment. Specifically, the control unit 11 selects a song that matches the user's range from among the registered songs of the customer indicated by the song use history information included in the attribute information, and has a “second difficulty” assignment song. Identify candidates. For example, the control unit 11 compares information representing a sound range constituting the singing part of the registered music with the user's sound range, and determines whether or not the registered music and the user's sound range are compatible. If there is no registered music that matches the user's range, the user's gender indicated in the attribute information is compared with the gender of the artist of the registered music, and the matching music is assigned to the “2nd difficulty” task music. You may specify it as a candidate. Alternatively, if there is no registered music that matches the user's range, the user adjusts the key when the user sings the registered music in the past, and the registered music and the user sings the registered music. Together with the key setting, it may be specified as a candidate song candidate of “second difficulty”.

  It is expected that the registered music registered as a favorite or eighteenth by the user has higher affinity (that is, better compatibility) with the user than the unregistered music. In addition, although the ranking music by age of the same age as the user is compatible with the user to some extent, it is considered that the music that the user is interested in is more compatible with the user. Based on such a viewpoint, in the first embodiment, it is assumed that the task music selected from the registered music is less difficult for the user than the music selected from the national ranking. ing.

  In S102 and S104, a plurality of songs may be identified as candidate song candidates for each of the “first difficulty level” and “second difficulty level” difficulty levels. In addition, when there are a plurality of karaoke devices 20 to which the users are logged in, based on the attribute information of the users who are logged into each karaoke device 20, the “first difficulty level” and the karaoke device 20 are individually set. You may comprise so that the subject music candidate of "2nd difficulty" may be specified.

  In S <b> 106, the control unit 11 sets the subject song candidate of “first difficulty” identified in S <b> 102 as the initial task song in the participation type event. In other words, among the candidate song candidates for each difficulty level identified in S102 and S104, the task song candidate with the higher difficulty level is set as the first task song.

  In S108, the control unit 11 sets a target condition and a holding period, which are constituent requirements of the participation type event. The target condition in the present embodiment is a score that serves as a reference for determining success or failure of the target with respect to individual scoring results when the user sings the task song. That is, if the scoring result when the user sings the task song is equal to or higher than the target condition, it is determined that the target condition has been achieved. The holding period is a time zone in which a participatory event is held (that is, from the start time to the end time). For example, the control unit 11 receives the input of each information of the target condition and the holding period from the administrator, and sets the target condition and the holding period to be applied to the participation type event. Or the control part 11 may set a target condition on the basis of the average value etc. of the result of scoring a subject music.

  In S <b> 110, the control unit 11 transmits a participation event holding notification to each karaoke apparatus 20. The notification of the participation type event includes information indicating the set task song, the target condition, and the holding period, and information such as the contents of a privilege provided when the target condition is achieved. In addition, when the subject music is individually set for each of the plurality of karaoke devices 20, the control unit 11 notifies the holding notification of the participation type event including information on each subject music to the karaoke device 20 corresponding to the subject music. Send.

  On the other hand, each karaoke apparatus 20 that has received the notification of the participation type event sets an operation mode for participating in the participation type event. At this time, the control unit 21 of the karaoke apparatus 20 causes the display 26 to display information indicating the subject song, the target condition, the content of the privilege, the holding period, and the like included in the notification of the participation type event. Announce the contents of the event.

  In S112, the control unit 11 starts measuring the elapsed time in the holding period. On the other hand, in the karaoke apparatus 20, when the operation mode of the participation type event is set, thereafter, evaluation information related to the subject song of the participation type event is transmitted to the event management server 10 during the set holding period. Specifically, when the control unit 21 of the karaoke apparatus 20 receives a request for performance of a task song, the control unit 21 scores a user's song performed during the performance of the task song using a predetermined scoring function. And the control part 21 transmits the evaluation information containing the information showing the score of the scoring result, and the identification information of the own karaoke apparatus 20 to the event management server 10.

  In S <b> 114, the control unit 11 acquires evaluation information transmitted from each karaoke apparatus 20. And in S116, the control part 11 compares the scoring result contained in the evaluation information acquired from each karaoke apparatus 20, and target condition, and determines whether the target condition was achieved for every karaoke apparatus 20. FIG. Here, it is determined that the target condition has been achieved on condition that the scoring result is equal to or higher than the target condition.

  In S118, the control unit 11 determines whether to end the participation type event. Specifically, the control unit 11 determines to end the participation type event when the participation period of the participation type event has expired. When the participation type event is not terminated (S118: NO), the control unit 11 returns to S114. On the other hand, when the participation type event is ended (S118: YES), the control unit 11 proceeds to S120.

  In S <b> 120, the control unit 11 transmits an event result notification that is information indicating success or failure of achievement of the target condition of the participation type event to each karaoke device 20. Specifically, the control unit 11 transmits an event result notification indicating that the target condition has been achieved to the karaoke apparatus 20 that has been determined to have achieved the target condition in S116. On the other hand, an event result notification indicating that the target condition has not been achieved is transmitted to the karaoke apparatus 20 that has not been determined to have achieved the target condition before the participation event has expired. After S120, the control unit 11 ends the event process.

  On the other hand, each karaoke apparatus 20 control unit 21 that has received the result notification of the participation type event displays information representing the content of the result notification on the display 26 and notifies the user of the result of the participation type event.

《Explanation of assignment song update processing》
The procedure of the task song update process (first embodiment) executed by the control unit 11 of the event management server 10 will be described with reference to the flowchart of FIG. This assignment song update process is performed in parallel with the event process under the condition that the target condition is determined not to be achieved in S116 when the participatory event is held in the event process described above (see FIG. 3). Executed. Moreover, when the some karaoke apparatus 20 is participating in a participation type event, the control part 11 performs a subject music update process for every karaoke apparatus 20 (henceforth the said karaoke apparatus).

  In S200, the control unit 11 determines whether or not a time corresponding to 50% of the holding period has elapsed since the time measurement was started in S112 of the event process. When the time corresponding to 50% of the holding period has not elapsed (S200: NO), the control unit 11 repeats the process of S200. On the other hand, when the time corresponding to 50% of the holding period has elapsed (S200: YES), the control unit 11 proceeds to S202.

  In S202, whether the evaluation result of the singing included in the evaluation information for the evaluation information acquired from the karaoke apparatus 20 from the start of the participatory event to the present time has achieved a predetermined difficulty reference point. Determine whether or not. The difficulty reference point is a score serving as a reference for determining whether or not it is necessary to lower the difficulty level of the subject song in the middle of the holding period. The difficulty reference point corresponds to the determination reference value in the present disclosure.

  The difficulty level reference point is set to a score lower than the target condition. For example, it is conceivable to apply a score obtained by subtracting a value corresponding to the ratio of the remaining time of the holding period from the target condition as the difficulty level reference point. As a result, if the customer has not achieved the difficulty reference point at a predetermined timing during the holding period (in the first embodiment, when 50% of the holding period has elapsed), the current assignment song is held as it is It can be estimated that it is difficult for the customer to achieve the target condition by the end of the period.

  When the evaluation result of the song up to the present time has achieved the difficulty level reference point (S202: YES), the control unit 11 ends the task song update process. On the other hand, when the evaluation result of the song up to the present time does not achieve the difficulty reference point (S202: NO), the control unit 11 proceeds to S204.

  In S204, the control unit 11 sets the candidate song candidate of “second difficulty” specified for the karaoke apparatus 20 in S104 of the event process as a new subject song. In S <b> 206, the control unit 11 notifies the karaoke apparatus 20 of the “second difficulty level” task song newly set in S <b> 204. After S206, the control unit 11 ends the task song update process.

  On the other hand, when a new task song is notified from the event management server 10, the control unit 21 of each karaoke apparatus 20 displays information representing the new task song on the display 26 and uses the fact that the task song has been updated. Notify customers. At the same time, the control unit 21 discards the setting of the previous assignment music and continues the operation mode related to the participation type event according to the new assignment music.

<< Effects of First Embodiment >>
According to 1st Embodiment, there exist the following effects.
Assuming that the music is compatible with the user's range, the ranking music by age, which is a music associated with the same age group as the user, is set as a highly difficult task music, and the music is of interest to the user. The registered music can be a low difficulty task music. As illustrated in FIG. 7, the registered music that the user has registered as a favorite or eighteenth has a higher affinity with the user than a non-registered music, and the degree of difficulty as a task music is high. Based on low viewpoint. Moreover, although the ranking music according to age in the same age as the user has good compatibility with the user, the music that the user is interested in is more compatible with the user than that.

  If the evaluation of the song does not satisfy the difficulty level reference point at a predetermined timing during the holding period of the participation type event, the task song can be changed to one having a low difficulty level. In this way, as illustrated in FIG. 7, the difficulty level of the task song decreases as the period of the participatory event elapses, and the affinity between the user and the task song improves accordingly. It is easier for customers to achieve the target conditions. Thereby, even if it is difficult to achieve the target condition in the original task song, the user is not given up on the way, and the user's willingness to participate can be increased and the staying time can be improved.

  In addition, the participation of events that are set based on attributes such as the registered music of the user and attributes such as the range and age of the user are expected to lead to the active participation of the user. It can contribute to the improvement of profits by improving the utilization rate of the karaoke service. In addition, since the task music that is flexible can be automatically set, the burden on the administrator is reduced.

Second Embodiment
Hereinafter, as an embodiment different from the above-described first embodiment, a second embodiment of processing executed by the event management server 10 regarding a participation type event will be described. The second embodiment is different from the first embodiment described above in that the setting of the difficulty level of the subject song is further subdivided from the first difficulty level to the fourth difficulty level. Note that, in the following description, matters common to the above-described first embodiment may be omitted after showing that fact.

<< Explanation of event processing >>
The procedure of event processing (second embodiment) executed by the control unit 11 of the event management server 10 will be described with reference to the flowchart of FIG. This process is executed at a predetermined timing (for example, a timing designated by the administrator) in the business period of the karaoke store where the event management server 10 is installed.

  In S300, the control part 11 acquires the attribute information of the user who is logging in to each karaoke apparatus 20 at the present time. About the content of the attribute information to acquire, it is the same as that of S100 of the above-mentioned 1st Embodiment.

  In S <b> 302, the control unit 11 corresponds to the “first difficulty level” based on the age of the customer indicated by the attribute information acquired in S <b> 300 and the national ranking for each age group distributed from the center server 30. Identify the candidate songs. The “first difficulty level” corresponds to the highest difficulty level in the second embodiment. Specifically, the control unit 11 is suitable for the user's range from among the ranking songs by age included in the national ranking corresponding to the user's age group, and is relatively lower in the national ranking. ”Is identified as a candidate song candidate of“ first difficulty ”. The method for specifying the music that matches the user's range is the same as in the first embodiment.

  In S304, the control unit 11 identifies a candidate song candidate corresponding to the “second difficulty level” from the age-specific ranking songs. The “second difficulty level” corresponds to the second highest difficulty level in the second embodiment. Specifically, the control unit 11 selects a song that is suitable for the user's range and is relatively “higher” in the national ranking from among the songs ranked by age and is a “second difficulty” task song. Identify candidates. In S302 and S304, if there is no age-ranking song that matches the user's range, a relatively lower or upper song is selected from the age-ranked songs that match the user's sex indicated by the attribute information. You may specify to the candidate music candidate of "1st difficulty" or "2nd difficulty".

  In S <b> 306, the control unit 11 specifies a candidate song candidate corresponding to the “third difficulty level” based on the attribute information acquired in S <b> 300. The “third difficulty level” corresponds to the third highest difficulty level in the second embodiment. Specifically, the control unit 11 matches the user's musical range from the registered songs of the user indicated by the song use history information included in the attribute information, and the number of times the user has sung. Among the registered songs, relatively “small” songs are identified as candidate song candidates for the “third difficulty level”.

  In S <b> 308, the control unit 11 identifies a candidate song candidate corresponding to the “fourth difficulty” from among the registered songs of the user. The “fourth difficulty level” corresponds to the lowest difficulty level in the second embodiment. Specifically, the control unit 11 selects, from among the registered music pieces of the user, music pieces that match the user's range and that the user has sung at a relatively “large” number among the registered music pieces. The subject song candidate of “4th difficulty” is specified. In S306 and S308, if there is no registered song that matches the user's range, a song that has a relatively high or low number of times of singing is selected from registered songs that match the user's gender indicated by the attribute information. You may specify to the candidate music candidate of "3rd difficulty" or "4th difficulty".

  In the second embodiment, similarly to the first embodiment described above, the task music selected from the registered music is less difficult for the user than the task music selected from the national ranking. Assuming that Furthermore, in the second embodiment, a registered song with a large number of singing is a problem with a relatively low difficulty level from the viewpoint that a song with a larger number of times the user sang among registered songs has a higher affinity with the user. It is set as a song, and a registered song with a small number of singings is set as a task song with a relatively high difficulty level. Also, among songs that are not registered songs, songs that are popular with people of the same age as the customer have more opportunities to listen to them, and from the perspective that their affinity with the customer is higher, songs with higher national rankings are selected. A low-difficulty task song is set, and a low-ranked song is set as a high difficulty task song.

  In S302 to S308, a plurality of pieces of music may be specified as assignment candidates for each of the “first difficulty level” to “fourth difficulty level” difficulty levels. In addition, when there are a plurality of karaoke devices 20 to which the users are logged in, based on the attribute information of the users who are logged in to each karaoke device 20, the “first difficulty level” to the individual karaoke devices 20. You may comprise so that the subject music candidate applicable to "4th difficulty" may be specified.

  In S310, the control unit 11 sets the candidate song candidate of “first difficulty” identified in S302 as the initial task song in the participation type event. That is, the task music candidate with the highest difficulty is set as the first task music among the task music candidates of each difficulty specified in S302 to S308.

  Thereafter, the processing contents of S312 to S324 are the same as the processing contents of S108 to S120 in the first embodiment described above. After S324, the control unit 11 ends the event process. On the other hand, each karaoke apparatus 20 control unit 21 that has received the result notification of the participation type event displays information representing the content of the result notification on the display 26 and notifies the user of the result of the participation type event.

《Explanation of assignment song update processing》
The procedure of the task song update process (second embodiment) executed by the control unit 11 of the event management server 10 will be described with reference to the flowchart of FIG. This assignment song update process is performed in parallel with the event process under the condition that the target condition is determined not to be achieved in S320 when the participation type event is held in the event process (see FIG. 5). Executed. Moreover, when the some karaoke apparatus 20 is participating in a participation type event, the control part 11 performs a subject music update process for every karaoke apparatus 20 (henceforth the said karaoke apparatus).

  In the second embodiment, the difficulty level reference point in the first embodiment described above is subdivided into three stages of a first difficulty level reference point to a third difficulty level reference point. This is different from the first embodiment. The first difficulty level reference point to the third difficulty level reference point are scores lower than the target condition, and the magnitude relationship is as follows: target condition> third difficulty level reference point> second difficulty level reference point> first difficulty level criterion It has become a point.

  In S400, the control unit 11 determines whether or not a time corresponding to 25% of the holding period has elapsed since the time measurement was started in S316 of the event process. When the time corresponding to 25% of the holding period has not elapsed (S400: NO), the control unit 11 repeats the process of S400. On the other hand, when the time corresponding to 25% of the holding period has elapsed (S400: YES), the control unit 11 proceeds to S402.

  In S402, for the evaluation information acquired from the karaoke apparatus 20 up to the current time after the participation type event is started, the control unit 11 has achieved the first difficulty reference point for the evaluation result of the singing included in the evaluation information. Determine whether or not. The first difficulty reference point is a score lower than the target condition, and is the lowest score among the first to third difficulty reference points. When the evaluation result of the singing up to the present time achieves the first difficulty level reference point (S402: YES), the control unit 11 proceeds to S408. On the other hand, when the evaluation result of the song up to the present time does not achieve the first difficulty reference point (S402: NO), the control unit 11 proceeds to S404.

  In S404, the control unit 11 sets the candidate song candidate of “second difficulty” specified for the karaoke apparatus 20 in S304 of the event process as a new subject song. In S <b> 406, the control unit 11 notifies the karaoke apparatus 20 of the subject song of the “second difficulty level” newly set in S <b> 404.

  In next step S408, the control unit 11 determines whether or not a time corresponding to 50% of the holding period has elapsed since the start of timing. When the time corresponding to 50% of the holding period has not elapsed (S408: NO), the control unit 11 repeats the process of S408. On the other hand, when the time corresponding to 50% of the holding period has elapsed (S408: YES), the control unit 11 proceeds to S410.

  In S410, whether the evaluation result of the singing included in the evaluation information has achieved the second difficulty reference point for the evaluation information acquired from the karaoke apparatus 20 until the present time after the participation type event is started, in S410 Determine whether or not. The second difficulty level reference point is a score lower than the target condition, and is the second lowest score among the first to third difficulty level reference points. When the evaluation result of the singing up to the present time has achieved the second difficulty level reference point (S410: YES), the control unit 11 proceeds to S416. On the other hand, when the evaluation result of the singing up to the present time does not achieve the second difficulty level reference point (S410: NO), the control unit 11 proceeds to S412.

  In S <b> 412, the control unit 11 sets the candidate song candidate of “third difficulty” specified for the karaoke apparatus 20 in S <b> 306 of the event process as a new issue song. In S <b> 414, the control unit 11 notifies the karaoke device 20 of the subject song of the “third difficulty level” newly set in S <b> 412.

  In next S416, the control unit 11 determines whether or not a time corresponding to 75% of the holding period has elapsed since the time measurement was started. When the time corresponding to 75% of the holding period has not elapsed (S416: NO), the control unit 11 repeats the process of S416. On the other hand, when the time corresponding to 75% of the holding period has elapsed (S416: YES), the control unit 11 proceeds to S420.

  In S420, the control unit 11 determines whether the evaluation result of the singing included in the evaluation information has reached the third difficulty reference point for the evaluation information acquired from the karaoke apparatus 20 up to the present time after the participation type event is started. Determine whether or not. The third difficulty level reference point is a score lower than the target condition, and is the highest score among the first to third difficulty level reference points. When the evaluation result of the singing up to the present time achieves the third difficulty level reference point (S420: YES), the control unit 11 ends the task song update process. On the other hand, when the evaluation result of the singing up to the present time does not achieve the third difficulty level reference point (S420: NO), the control unit 11 proceeds to S422.

  In S422, the control unit 11 sets the candidate song candidate of the “fourth difficulty” identified for the karaoke device 20 in S308 of the event process as a new task song. In S424, the control unit 11 notifies the karaoke apparatus 20 of the subject song of the “fourth difficulty” newly set in S422. After S424, the control unit 11 ends the task song update process.

  On the other hand, when a new task song is notified from the event management server 10, the control unit 21 of each karaoke device 20 displays information representing the new task song on the display 26 and the task song is updated. To inform customers. At the same time, the control unit 21 discards the setting of the previous assignment music and continues the operation mode related to the participation type event according to the new assignment music.

<< Effects of Second Embodiment >>
According to 2nd Embodiment, in addition to the effect of the above-mentioned 1st Embodiment, there exist the following effects further.
As illustrated in FIG. 7, a registered music with a relatively low difficulty level is obtained from a viewpoint that a song with a larger number of times the user has sung among registered songs has a higher affinity with the user. It can be set as a song, and a registered song with a small number of singings can be set as a task song with a relatively high difficulty level. Also, among the songs that are not registered songs, the songs that are popular with people of the same age as the customer have more opportunities to listen to them, and the top songs in the nationwide ranking are compared from the viewpoint that the affinity with the customer is higher It is possible to set a task song with a low difficulty level and set a lower-order song as a task song with a relatively high difficulty level.

  Then, at a plurality of timings during the holding period (for example, when 25%, 50%, and 75% of time have elapsed), depending on the success or failure of achievement of the difficulty reference point according to each timing, The difficulty level can be lowered step by step.

  Further, the difficulty level reference point is set so that the earlier the lower timing, the higher the difficulty level, and the higher the later timing. As a result, it is possible to have the challenge song with as high a difficulty as possible, unless the difficulty level of the issue song is excessively high at the beginning of the holding period. By doing so, the participatory event can be rewarding for the user. On the other hand, since the target condition becomes easier to achieve as the remaining time of the holding time decreases, it is possible to prevent the user from giving up until the end. In addition, for the customers who participated from the middle of the participatory event period, it is possible to set a task song with a degree of difficulty corresponding to the remaining time of the period, so that even if the user is in the middle of the period, It is possible to hold participatory events that are easy to challenge.
