  By the way, in order to increase the motivation of customers to come to the karaoke store and to promote the use of the karaoke service, it is conceivable to give a privilege according to the usage record of the karaoke service. For example, a specific holding period is set, and a privilege is given on the condition that the accumulation of song scores and the like satisfies the standard during the holding period. As a result, the user will enthusiastically repeat the song in order to obtain a privilege during the holding period, and it is expected that the staying time of the user will be increased. Furthermore, by implementing the service of giving such a privilege as a participatory event in which a plurality of users cooperate to achieve a common goal, it is possible to expect many customers to come to the store. Moreover, by holding such a participatory event during a time when the number of visitors is small, it is considered that the utilization rate of the karaoke room can be increased and the profit of the karaoke store can be increased.

  In such a participatory event, the administrator can estimate the number of users and the singing skills of the users and set the length of the holding period and the target height to be achieved by the users. Conceivable. However, it is difficult to properly set the event period and goals based on speculation. For example, if the goal is set too high for the skill of the customer or the length of the holding period, it may be difficult to achieve the target during the holding period. In such a case, a customer who gives up on achieving the goal may leave the shop early without waiting for the expiration of the holding period, and it may not be possible to extend the staying time of the customer as desired. For this reason, it is necessary to devise a way for more users to reach their goals and stay until the end of the event.

  Therefore, an object of the present disclosure is to provide a technique for increasing the motivation of users and improving their staying time in a participatory function in which users of a plurality of karaoke devices cooperate to achieve a goal.

Furthermore, when the extension holding period is set by the extension setting unit, the achievement determining unit is configured to determine whether or not the target condition is achieved before the extension holding period expires.

  According to the above configuration, when it is estimated that it is impossible to achieve the target condition set for the participatory function during the holding period, the extended holding period is automatically changed according to the progress of the aggregate value of the singing evaluation. It is possible to notify the customer of the extended holding period. As a result, even if it becomes difficult to achieve the target conditions within the time, the new extended holding period will be set so that the users will not give up and stay more motivated to participate. The time can be improved.

  In the above configuration, the following may be further performed. That is, the estimation unit may achieve the target condition by the end of the holding period if the aggregated value at that time has not reached the predetermined level at the predetermined time point during the holding period. It is configured to assume that it is impossible. With such a configuration, it is possible to determine whether or not to set the extended holding period at a predetermined time point during the holding period.

  Alternatively, it may be configured as follows. That is, the estimation unit calculates a predicted aggregate value that is a value obtained by predicting the aggregate value of evaluations at the end time of the holding period, and achieves the target condition according to the difference between the calculated aggregate predicted value and the target condition. Is configured to estimate whether or not it is possible. Note that the predicted aggregate value is statistically calculated from the current aggregate value, the estimated number of times of singing performed by the participating terminals in the remaining time until the holding period expires, and the evaluation represented by the evaluation information. It is calculated based on the estimated evaluation per song performed. With such a configuration, it is possible to determine at any time whether it is necessary to set the extended holding period based on the predicted aggregate value.

[Explanation of management server processing]
The procedure of the process executed by the control unit 11 of the management server 10 will be described with reference to the flowchart of FIG. This process is repeatedly executed at a predetermined control cycle while the management server 10 is operating.

  In S100, the control unit 11 determines whether or not an operation instruction for setting a target condition in the participation-type event has been received. When the operation instruction for setting the target condition is received (S100: YES), the control unit 11 proceeds to S102. On the other hand, when the operation instruction for setting the target condition has not been received (S100: NO), the control unit 11 repeats S100. In S102, the control unit 11 initializes the contents of the management table managed in the memory.

  Here, the configuration of the management table will be described with reference to FIG. 4A. As illustrated in FIG. 4A, in the management table, information items such as a target condition, a holding period, and a target achievement privilege are described as information indicating the constituent requirements of the participation type event. The information item of the target condition describes a common target condition that users of a plurality of karaoke devices 20 in the store should achieve jointly in the participation-type event. In the case of FIG. 4A, the total score is set as the target condition. The target condition of the total score is an achievement criterion regarding the total score of all the singing score results performed in all the karaoke devices 20 (hereinafter, also referred to as participating terminals) that have decided to participate under the target condition. Further, in the information item of the holding period, information indicating a time zone (that is, from the start time to the end time) in which the participation-type event based on the above target condition is held is described.

  The information item of the goal achievement privilege describes the content of the privilege given to the user of the participating terminal when the target condition is achieved. Each piece of information on the target condition, the holding period, and the target achievement privilege is designed by, for example, the manager of the karaoke store and registered in the management server 10. In addition, the management table is provided with information items that represent the result of totaling the target conditions for each of the plurality of karaoke devices 20 installed in each room. In the example of FIG. 4A, information items such as “subtotal score” and “participation presence / absence” are provided for each room in which each karaoke device 20 is installed.

  The subtotal score is a value obtained by adding the scores of the scoring results of the songs performed while participating in the corresponding karaoke device 20 under the target condition. The presence / absence of participation is information indicating whether or not the corresponding karaoke device 20 participates in the participation-type event under the target condition, “1” indicates participation, and “0” indicates non-participation. The information about the subtotal score and the presence / absence of participation is information that is automatically updated by the management server 10 based on the information notified from each karaoke device 20. Further, in the management table, the total score obtained by summing the subtotal scores of the respective karaoke devices 20 participating in the participation type event is recorded.

  In the initialization in S102, the control unit 11 registers each information of the target condition, the holding period, and the target achievement privilege input by the administrator in the corresponding information item in the management table. Further, the values of the subtotal score of each room and the presence / absence of participation in the management table are reset to “0”. That is, the initial state illustrated in FIG. 4A is set.

  Returning to the description of the flowchart in FIG. In S104, the control unit 11 notifies the plurality of karaoke devices 20 connected to the LAN 50 of invitation to participate in the participation type event. This invitation for participation is information for notifying the karaoke device 20 that a participation-type event is held and inquiring each karaoke device 20 as to whether or not to participate, and information such as the target condition registered in S102. included.

  In S106, the control unit 11 determines whether or not the participation presence / absence notification has been received from the karaoke device 20. The participation presence / absence notification is information transmitted in S406 and S426 of the karaoke device process (see FIG. 8) described later. In this participation presence / absence notification, the identification information of the karaoke device 20 of the transmission source, the information of “participation present” indicating participation in the participation type event, or the cancellation of participation in the participation application by exiting the store is displayed. No participation ”information is included. When the participation presence / absence notification is received (S106: YES), the control unit 11 proceeds to S108. On the other hand, when the participation presence / absence notification has not been received (S106: NO), the control unit 11 proceeds to S110.

  In S108, the control unit 11 updates the content of “participation presence / absence” in the management table for the room number corresponding to the karaoke device 20 that is the transmission source of the participation presence / absence notification. Specifically, the control unit 11 updates the value of “participation presence / absence” corresponding to the room number in the management table to “1” when receiving the participation presence / absence notification including the information indicating participation participation. The value of “participation presence / absence” in the management table is changed to “1” in accordance with the transmission / reception of the participation notification, so that the karaoke device 20 is treated as a participation terminal in the management server 10.

  Regarding the karaoke device 20 that has not transmitted the information indicating the participation, the value of “presence or absence of participation” in the management table remains “0” and is treated as a non-participation terminal by the management server 10. On the other hand, when the control unit 11 receives the participation presence / absence notification including the information indicating no participation, the control unit 11 updates the value of “participation presence / absence” corresponding to the room number in the management table to “0”. However, information items for subtotal points will be maintained without updating.

  In S110, the control unit 11 determines whether or not the scoring information is received from the participating terminal. The scoring information is the information transmitted in S418 of the karaoke device processing (see FIG. 8) described later. This scoring information is information indicating the score of the scoring result of the song performed at the transmission source participating terminal. When the scoring information is received (S110: YES), the control unit 11 proceeds to S112. On the other hand, when the scoring information has not been received (S110: NO), the control unit 11 proceeds to S114. In S112, the control unit 11 adds the score represented by the scoring information to the value of the “subtotal score” in the management table for the room number corresponding to the participating terminal that is the transmission source of the scoring information, and updates the total score. .

  Here, the state of the management table in the middle of the participation type event will be described with reference to FIGS. 4B and 4C. First, the case of FIG. 4B represents a state in which the achievement status of the target condition has progressed to some extent from the initial state illustrated in FIG. 4A. In the example of FIG. 4B, the participation presence / absence value for the room numbers 101, 102, and 103 is “1”, which indicates that the karaoke device 20 in each room participates in the participation type event. And the score of the scoring result of the song performed in each karaoke device 20 participating in the participation type event is added to the column of each subtotal score. On the other hand, with respect to the room number 104, the participation presence / absence value remains “0”, indicating that the karaoke device 20 in the room 104 is not participating in the participation type event. In the case of FIG. 4B, the target condition for the total score has not been achieved.

  Next, the case of FIG. 4C represents a state in which the achievement status of the target condition has progressed to some extent from the status illustrated in FIG. 4B. In the example of FIG. 4C, the value of presence / absence of participation has changed from “1” to “0” for the room number 101, which represents a state in which the user has left the store during the holding period of the participation type event. On the other hand, the value of presence / absence of participation in the room numbers 102 and 103 is “1”, which indicates that the karaoke device 20 in each room continues to participate in the participation-type event. Then, the score of the singing score performed in each karaoke device 20 that is currently participating in the participation-type event and the karaoke device 20 that the user withdrew during the process is added to each subtotal score column. There is. On the other hand, with respect to the room number 104, the participation presence / absence value remains “0”, indicating that the karaoke device 20 in the room 104 is not participating in the participation type event. In the case of FIG. 4C, the target condition for the total score is unachieved.

  Returning to the description of the flowchart in FIG. In S114, the control unit 11 determines whether or not a transmission request for the management table has been received from the karaoke device 20. This transmission request is information transmitted in S412 of the karaoke device processing (see FIG. 8) described later. When the transmission request of the management table is received (S114: YES), the control unit 11 proceeds to S116. On the other hand, when there is no request for transmission of the management table (S114: NO), the control unit 11 proceeds to S118. In S116, the control unit 11 transmits the data of the management table to the karaoke device 20 that is the request source.

  In S118, the control unit 11 determines whether or not the target condition is achieved based on the management table. Specifically, the control unit 11 sets the target score on the condition that the total score obtained by summing the subtotal scores of each room (including the room that has left the store on the way) in the management table is equal to or more than the total score of the target condition. Judge that the conditions are met. When the target condition is not achieved (S118: NO), the control unit 11 proceeds to S120. In S120, the control unit 11 compares the current time with the holding period registered in the management table, and determines whether the holding period has expired. When the holding period has not expired (SS120: NO), the control unit 11 proceeds to S122.

  In S122, the control unit 11 executes extension determination processing. In the extension determination process, the control unit 11 estimates whether or not the target condition can be achieved before the holding period expires, depending on the total score of the management table and the progress status of the holding period. Then, when it is estimated that it is impossible to achieve the target condition, the control unit 11 sets an extended holding period which is a time for extending the holding period.

  Here, the first embodiment of the extension determination process executed in S122 will be described with reference to the flowchart of FIG. In S200, the control unit 11 determines whether the current time corresponds to the determination time. The determination time is a time set to an arbitrary time during the holding period (for example, a time when 50 to 75% of the holding period is consumed). When the current time does not correspond to the determination time (S200: NO), the control unit 11 proceeds to S206. On the other hand, when the current time corresponds to the determination time (S200: YES), the control unit 11 proceeds to S202.

  In S202, the control unit 11 compares the current total score in the management table with the achievement level value at the determination time. The achievement level value is a standard for estimating whether or not it is possible to achieve the target condition before the event period expires. For example, under the condition that the total score is proportional to time, assume a model of the function that the total score at the end time of the holding period reaches within a certain range based on the target condition, and from this model, the total score at the judgment time It is conceivable to apply the derived value as the achievement level.

  In S204, the control unit 11 estimates, based on the comparison result in S202, whether or not the target condition can be achieved before the holding period expires. Specifically, the control unit 11 estimates that the target condition can be achieved when the current total score is equal to or higher than the achievement level value. On the other hand, if the current total score is less than the achievement level, it is presumed that the target condition cannot be achieved. When it is estimated that the target condition can be achieved (S204: YES), the control unit 11 proceeds to S206. In S206, the control unit 11 determines not to extend the holding period, and ends the extension determination process.

  On the other hand, when it is estimated in S204 that the target condition cannot be achieved (S204: NO), the control unit 11 proceeds to S208. In S208, the control unit 11 calculates an extended holding period obtained by extending the end time of the current holding period. Specifically, the control unit 11 predicts the time required for the current total score to reach the target condition based on the current total score and the progress of the holding period, and based on the required time. Set an extension period.

  A specific method for calculating the extension period will be described with reference to the graph in FIG. In the graph illustrated in FIG. 6, the horizontal axis represents the time corresponding to the holding period of the participation-type event, and the vertical axis represents the total score of the singing scoring results performed at each participating terminal.

  In FIG. 6, the solid line TA is a graph showing the transition of the total score of the scoring results of the songs performed at the participating terminals in rooms 101, 102, and 103. In the case of FIG. 6, it is assumed that it is presumed that it is impossible to achieve the target condition at the time of 10:45 in the initial holding period from 10:00 to 11:00. ing. It is assumed that, among rooms 101 to 103, the guest in room 101 has already left the store. In the extension determination process of the first embodiment, if the total score TAa at the determination time 10:45 is less than the achievement level value TR corresponding to this determination time, it is impossible to achieve the target condition. It is estimated to be.

  In the present embodiment, the transition of the total score is represented by a straight line to estimate whether or not the target condition is achieved. However, even when the transition of the total score is not a straight line, for example, a well-known prediction method such as a moving average method. Can be used. In addition, the determination of the determination time in S200 is performed after a fixed time (45 minutes after the start of 10:00 in this embodiment) from the start time, so that the total score immediately after the start is small (there is little data). The influence of the estimation error that occurs in some cases is reduced.

  At the time when it is estimated that it is impossible to achieve the target condition, the control unit 11 takes into consideration the total score expected to be acquired in the future for each room in which participation continues, and adds the total score. Estimate the time required to reach the target condition. The control unit 11 sets the extended holding period based on the estimated required time. Specifically, the extended holding period may be set by directly adding the required time estimated from the current time, or the extended holding period may be set by adding a predetermined weight to the estimated required time and added. Good.

  In the case of FIG. 6, the increase rate of the subtotal points per unit time from the start time of the holding period to the determination time is calculated for the room 102 and the room 103 in which participation continues at the determination time 10:45. The time required for the total score TA to reach the target condition can be predicted by dividing the difference between the target condition and the total score TAa at the determination time by the increase rate of the room 102 and the room 103. The transition of the total score TA in this case is as shown by the broken line portion of the graph. Therefore, the control unit 11 sets the extended holding period based on the estimated required time. In the example of FIG. 6, it is assumed that the end time of the holding period is extended from 11:00 to 11:40.

  Further, as a different embodiment from the above-described first embodiment, a second embodiment of the extension determination process executed in S122 will be described with reference to the flowchart of FIG. In S300, the control unit 11 calculates a predicted value of the total points at the end time of the holding period. Specifically, the control unit 11 adds the subtotal score predicted to be acquired in the remaining time of the holding period to the total score at the present time for each room in which participation continues at the present time, and Calculate the predicted total score. In addition, the value obtained by dividing the actual subtotal score of each room at the current time by the time from the start time to the current time is taken as the increase rate of the subtotal score per unit time, and by multiplying this increase rate by the remaining time, It is possible to predict the subtotal score that will be acquired in the room during the remaining time.

  In S302, the control unit 11 estimates, based on the predicted value calculated in S300, whether or not the target condition can be achieved before the holding period expires. Specifically, when the predicted value of the total score reaches the score in a predetermined range based on the target condition, the control unit 11 estimates that the target condition can be achieved. On the other hand, when the predicted value of the total score does not reach the score of the predetermined range based on the target condition, the control unit 11 estimates that the target condition cannot be achieved. When it is estimated that the target condition can be achieved (S302: YES), the control unit 11 proceeds to S304. In S304, the control unit 11 determines not to extend the holding period and ends the extension determination process.

  On the other hand, when it is estimated in S302 that the target condition cannot be achieved (S302: NO), the control unit 11 proceeds to S306. In S306, the control unit 11 calculates an extended holding period obtained by extending the end time of the current holding period. Specifically, the control unit 11 predicts the time required for the current total score to reach the target condition based on the current total score and the progress of the holding period, and the predicted required time. Set an extension period based on. Note that the method of calculating the extension period is the same as that of S208 of the above-described first embodiment (see FIG. 5).

  Returning to the description of the flowchart in FIG. In S124, the control unit 11 branches the process according to the determination result in the extension determination process of S122. When the extension holding period is calculated in the extension determination process (S124: YES), the control unit 11 proceeds to S126. On the other hand, when it is determined in the extension determination process that the holding period is not extended (S124: NO), the control unit 11 returns to S106.

  In S126, the control unit 11 updates the "holding period" of the management table according to the extension holding period calculated in the extension determination process of S122. Here, the state of the management table when the holding period is extended will be described with reference to FIG. 4D. The example of FIG. 4D represents a state in which the holding period is extended by the control unit 11 after a further time has elapsed from the state illustrated in FIG. 4C. In the example of FIG. 4D, the end time of the holding period is extended from 11:00 at the beginning to 11:40.

  Returning to the description of the flowchart in FIG. In S128, the control unit 11 notifies each participating terminal of information indicating that the holding period has been extended (notice of extended holding period). This extended holding period notification includes information indicating that the holding period has been extended and information indicating a management table that reflects the extended holding period set in S122. After S128, the control unit 11 returns to S106.

  On the other hand, when it is determined in S118 that the target condition is achieved (S118: YES), the control unit 11 proceeds to S130. In S130, the control unit 11 notifies the administrator of information indicating that the target condition has been achieved. For example, the control unit 11 displays a message indicating that the target condition is achieved, a room number corresponding to the participating terminal, and image information such as content of the privilege provided to the guest of the room corresponding to the participating terminal. It is displayed on the display unit 14. In S132, the control unit 11 notifies each participating terminal of information indicating that the target condition has been achieved (target condition achievement notification). After S132, the control unit 11 returns to S100 and waits for the setting of the target condition for the next participation type event.

  On the other hand, when it is determined in S120 that the holding period has expired (S120: YES), the control unit 11 proceeds to S134. In S134, the control unit 11 notifies each karaoke device 20 of information indicating that the participation-type event has ended. This ends this participatory event. After S134, the control unit 11 returns to S100 and waits for the setting of the target condition for the next participation type event.

[Explanation of Karaoke device processing]
The procedure of the process executed by the control unit 21 of the karaoke device 20 will be described with reference to the flowchart of FIG. This process is repeatedly executed at a predetermined control cycle while the karaoke device 20 is operating.

  In S400, the control unit 21 determines whether or not a notification of invitation to participate in the participation-type event has been received from the management server 10. This participation invitation notification is information transmitted in S104 of the above-described management server process (see FIG. 3). When the participation invitation notification is received (S400: YES), the control unit 21 proceeds to S402. On the other hand, when the invitation for participation invitation has not been received (S400: NO), the control unit 21 repeats S400.

  In S402, the control unit 21 displays the participation acceptance screen based on the received participation invitation notification on the display 26. This participation acceptance screen includes, for example, image information indicating the target condition of the participation type event, and a graphical user interface (GUI) to which a function of accepting an operation for determining whether to participate in the participation type event is assigned. In S404, the control unit 21 determines whether or not an operation instruction for determining participation is input by the user. It is assumed that the operation instruction is input by the user via the operation unit 24 or a remote control terminal (not shown), for example. When the operation instruction to determine participation is input (S404: YES), the control unit 21 proceeds to S406. On the other hand, when the operation instruction for deciding not to participate in the participation-type event is input (S404: NO), the control unit 21 returns to S400.

  In S <b> 406, the control unit 21 transmits a participation presence / absence notification including the identification information of the own karaoke device 20 and the “participation present” information indicating participation in the participation type event to the management server 10. When the management server 10 receives this participation presence / absence notification, the management server 10 handles the karaoke device 20 as a participation terminal.

  In S408, the control unit 21 determines whether or not the target condition achievement notification has been received from the management server 10. The target condition achievement notification is information transmitted in S130 of the management server process (see FIG. 3). When the target condition achievement notification is received (S408: YES), the control unit 21 proceeds to S410. In S410, the control unit 21 causes the display 26 to display an effect image regarding achievement of the target condition. This effect image includes, for example, image information such as a message for notifying the user that the target condition has been achieved. After S410, the control unit 21 returns to S400.

  On the other hand, when it is determined that the target condition achievement notification is not received in S408 (S408: NO), the control unit 21 proceeds to S412. In S412, the control unit 21 requests the management server 10 to transmit the management table and acquires the data in the management table (see FIG. 4). In S414, the control unit 21 causes the display 26 to display an effect image that encourages the user to achieve the target condition based on the management table acquired in S412.

  Here, a specific example of the effect image that encourages the achievement of the target condition will be described with reference to FIG. 9A. The example of FIG. 9A shows a situation in which the effect image 30a that encourages the achievement of the initial target condition is displayed by being superimposed on the background image displayed in the performance processing of the karaoke piece. In the effect image 30a, image information of 30b, 30c, and 30d is drawn using a space other than the display area of the lyrics telop corresponding to the music being played. 30b is image information indicating that the own karaoke device 20 is participating in a participation-type event.

  30c is image information indicating the achievement status of the target condition. In the example of FIG. 9A, the subtotal score of the song scoring result in each room is described as the image information 30c. 30d is image information that represents the remaining total points required to achieve the target condition and the benefits obtained by achieving the target condition.

  Returning to the description of the flowchart in FIG. In S416, the control unit 21 determines whether or not a new song scoring result has been created in the own karaoke device 20. When the song scoring result is created (S416: YES), the control unit 21 proceeds to S418. In S418, the control unit 21 transmits the rating information including the identification information of the own karaoke apparatus 20 and the score of the song rating result to the management server 10. On the other hand, when the song scoring result is not created (S416: NO), the control unit 21 proceeds to S420.

  In S420, the control unit 21 determines whether or not the extended holding period notification has been received from the management server 10. The target condition reset notification is the information transmitted in S128 of the management server process (see FIG. 3). When the notification of the extended holding period is received (S420: YES), the control unit 21 proceeds to S422. In S422, the control unit 21 causes the display 26 to display the effect image that reflects the extended holding period based on the management table included in the notification of the extended holding period. On the other hand, when the extended holding period notification is not received in S420 (S420: NO), the control unit 21 proceeds to S424.

  Here, a specific example of the effect image displayed in S422, which reflects the extended holding period, will be described with reference to FIG. 9B. The example of FIG. 9B shows a situation in which the effect image 31a reflecting the extended holding period is displayed by being superimposed on the background image displayed in the performance processing of the karaoke music. Image information 31b, 31c, and 31d is drawn on the effect image 31a by using a space other than the display area of the lyrics telop corresponding to the music being played. 31b is image information notifying that the holding period of the participation type event has been extended.

  Reference numeral 31c is image information representing the achievement status of the target condition. In the case of FIG. 9B, the subtotal score of the song scoring result in each room is described as the image information 31c. 31d is image information that represents the remaining total score required to achieve the target condition and the additional privilege obtained by achieving the target condition.

  Returning to the description of the flowchart in FIG. In S424, the control unit 21 determines whether or not the user has received an instruction to leave the store. When the user receives the instruction to leave the store (S424: YES), the control unit 21 proceeds to S426. In S426, the control unit 21 transmits a participation presence / absence notification including the identification information of the own karaoke apparatus 20 and the information of “no participation” indicating cancellation of participation in the participation type event to the management server 10. When the management server 10 receives this participation presence / absence notification, the management server 10 treats the user of the karaoke device 20 as having left the room. After S426, the control unit 21 returns to S400.

  On the other hand, if the store exit instruction has not been received in S424 (S424: NO), the control unit 21 proceeds to S428. In S428, the control unit 21 determines whether an event end notification has been received from the management server 10. The event end notification is information transmitted in S134 of the management server process (see FIG. 3). When the event end notification is received (S428: YES), the control unit 21 returns to S400. On the other hand, when the event end notification has not been received (S428: NO), the control unit 21 returns to S408.

[effect]
The karaoke system 1 of the embodiment has the following effects.
If it is estimated that it is impossible to achieve the target condition during the holding period in the participation type event with the holding period set, the extended holding period will be automatically set according to the progress of the total score of the singing evaluation. The customer can be notified of the extended holding period. As a result, even if it becomes difficult to achieve the target conditions within the time, the new extended holding period will be set so that the users will not give up and stay more motivated to participate. The time can be improved.

  In addition, at the given judgment time during the holding period, is it possible to achieve the target condition by the end of the holding period based on whether or not the total score at that judgment time has reached the achievement level value? It can be estimated whether or not. Alternatively, a predicted value that is a value that predicts the total points at the end time of the holding period is calculated, and it is estimated whether or not the target condition can be achieved according to the difference between the calculated predicted value and the target condition. can do.

  In addition, based on the current total score and the progress of time during the event period, the total time to be acquired in the future is predicted to reach the target condition, the required time is estimated, and the extended time is held based on the predicted time. You can set the period. By doing so, the event period can be extended until the time when the customer can achieve the target condition. Thereby, it is possible to prevent the customer from giving up the achievement of the target condition on the way.
