Utilization of “Nudge” in providing information for energy conservation and power saving promotion measures: Case study of energy report for household in the US. Report of Central Research Institute of Electric Power Industry. Y, 2013, 12035: Intro 1-3, 1 -31.

  As described above, in the prior art, a smartphone or a game is prevented from being used for a long time simply by performing a rule-based warning or prior forced management. However, in general warnings and the like as in the prior art, the user often feels pressing, and the effect of suppressing long-term use is limited. That is, the conventional technique has a limited suppression effect in that it does not provoke the user's own willingness to actively stop using for a long time.

  On the other hand, in recent years, as introduced in Non-Patent Document 2 and the like, a method for promoting natural behavioral change using a behavioral psychological element called nudge has been proposed. Nudge encourages user behavior change without forcibly changing user behavior. For example, in the case of US Opower, which is disclosed in Non-Patent Document 3, instead of a message such as “Let's turn off cooling to save money” in order to prevent excessive use of electricity, I'm nudging the savings with the message "I'm turning off the air. You are with me". This uses psychology such as "showing my position objectively" or "I want to stay near the average (I don't want to be off)".

  Therefore, it is expected that a method such as Nudge will be applied to this issue (such as the suppression of long-term use of smartphones).

  In view of the above-described problems of the conventional technology, an object of the present invention is to provide an information terminal and a program that can be appropriately used by a user.

In order to achieve the above object, the present invention is an information terminal for notifying a user of a usage record,
A reference setting unit for setting a reference value of the actual use record, a result acquisition unit for acquiring a use result of the information terminal by the user, and a comparison result between the acquired use result and the set reference value. And a notification unit that generates optimization promotion information for use of the information terminal and notifies the user of the optimization promotion information and the acquired usage record.

  Further, the present invention is a program for causing a computer to function as the information terminal.

  ADVANTAGE OF THE INVENTION According to this invention, the willingness to correct a utilization track record effectively can be alerted to a user by notifying the utilization track record of the information terminal by a user using nudge.

It is a functional block diagram of a notification system. It is a figure which shows the structural example of a notification system. It is a figure which shows the example of the hardware constitutions of an information terminal (and server). It is a figure which shows the example notified by a facial expression icon in a notification part. It is a figure which shows the example notified by a facial expression icon in a notification part. It is a figure which shows four type classification | category (character type) in the player of an online game.

  First, Nudge will be explained. Nudge is defined in Non-Patent Document 1 as follows. In other words, it is defined as “any element of a selection architecture that changes people's behavior in a predictable way without prohibiting selection or changing economic incentives significantly”. Therefore, it is necessary for the user to naturally take action by giving some information to the user, and generally, a technique applying psychology is often used.

  The present invention proposes a technique for reducing the usage time of smartphones and games using the psychology of “I do not want to deviate significantly from the average from many people”. Specifically, feedback of the usage time (or unauthorized use) to the user is performed using the facial expression of a specific character.

  FIG. 1 is a functional block diagram of a notification system according to an embodiment. The notification system 30 includes the information terminal 10 and the server 20. The information terminal 10 includes an information acquisition unit 1, a reference setting unit 2, a result acquisition unit 3, a notification unit 4, and a timing determination unit 5. The server 20 includes an information collection unit 6 and a performance collection unit 7. The processing outline of each part is as follows.

  The information acquisition unit 1 acquires user information (for example, a user profile) of a user who uses the information terminal 10 by receiving a user input. As shown in the figure, the acquired user information can be referred to in the reference setting unit 2. Further, the acquired user information may be transmitted to the information collecting unit 6 of the server 20 so as to be aggregated together with user information of other users in the server 20.

  The reference setting unit 2 sets a reference value regarding the usage status of the information terminal 10 by the user, which is used when the notification unit 4 notifies the user who uses the information terminal 10. As shown in the figure, in the setting in the reference setting unit 2, various information can be referred to, the user information of the user acquired by the information acquisition unit 1, the usage record of the user acquired by the result acquisition unit 3 Any combination of information obtained from the information collecting unit 6 (a grouping result described later) and information obtained from the result collecting unit 7 (used results of other users described later) may be referred to.

  The result acquisition unit 3 acquires the result of the usage status of the information terminal 10 by the user. The result can be acquired as a result of the user using the application for each type of application executed on the information terminal 10 (a game if the information terminal 10 is a game machine). As shown in the figure, the acquired results can be referred to by the notification unit 4 and the reference setting unit 2, and are aggregated by being transmitted to the result collection unit 7 of the server 20 (along with the results of other users). You may make it.

  The notification unit 4 compares the reference value set by the reference setting unit 2 with the result acquired by the result acquisition unit 3, and notifies the user of the information terminal 10 to improve the use situation. Do. In the notification, the user's willingness to improve is promoted by using the Nudge method.

  Specifically, the notification unit 4 generates the optimization promotion information in a form reflecting the comparison result between the reference value and the actual result (that is, the form using the nudge), and uses it for the user together with the optimization promotion information. Notify the status of the situation. Although the details of the optimization promotion information will be described later, by receiving the notification of the information, the user should improve the usage when the user's usage record of the information terminal 10 is poor (for example, when it is overused). In the case where the usage record is good (for example, when the user is using it with moderation instead of being overused), the user will be motivated to maintain the good result as it is. .

  In addition, as a method of reflecting the comparison between the reference value and the actual result in the optimization promotion information generated by the notification unit 4, a method of giving the comparison result between the reference value and the actual result as information, or as described later It is possible to use a method of giving information such as a message for prompting the user to optimize the usage record, or any combination of these methods and other methods. As will be described later, the message that prompts the optimization is generated by the notification unit 4 as a message having a predetermined content corresponding to the comparison result (and the user's profile, etc.) between the reference value and the actual result, so that the nudge is given to the user. It becomes possible to motivate the optimization of behavior by the method.

  The timing determination unit 5 determines a timing suitable for performing notification in the notification unit 4 by monitoring a user's operation status and the like with respect to the information terminal 10, and instructs the notification unit 4 of the timing. The notification unit 4 can notify the user at a time desired by the user, and can notify the user at the timing instructed by the timing determination unit 5.

  The information collection unit 6 acquires and collects user information of each user from the information acquisition unit 1 in the information terminal 10 of each user. The result collection unit 7 acquires and collects the use results of each user from the result acquisition unit 3 in the information terminal 10 of each user. As will be described in detail later, each of the units 6 and 7 may transmit the result of processing the collected information to the reference setting unit 2.

  FIG. 2 is a diagram illustrating a configuration example of a notification system according to an embodiment. The notification system 30 includes an information terminal 10 for each user configured as the information terminal 10 shown in FIG. 1 (the information terminal 10A of the user A, the information terminal 10B of the user B, as an example of a part thereof in FIG. The information terminal 10C of the user C is shown.) And the server 20.

  Although FIG. 1 shows the relationship between one information terminal 10 and the server 20, as shown in the example of FIG. 2, each information terminal 10 exists for each user and communicates with the server 20 via the network N. . In FIG. 2, an example of three users is shown, but the number of users and the number of information terminals 10 may be arbitrary. The information collecting unit 6 and the result collecting unit 7 of the server 20 shown in FIG. 1 collect each information from the information terminal 10 of each user as in the example of FIG.

  Various general information devices can be used for the information terminal 10. For example, a smartphone, a feature phone, a game machine (which may be a portable game machine or a stationary game machine), a tablet terminal, a notebook personal computer, a desktop personal computer, and other various information devices can be employed as the information terminal 10.

  The information terminal 10 can be realized by a computer having a general hardware configuration. FIG. 3 is a diagram illustrating an example of a hardware configuration for realizing the information terminal 10.

  As shown in FIG. 3, the information terminal 10 includes a CPU (Central Processing Unit) 31, a RAM 32 as a main storage device that provides a work area to the CPU 31, a ROM 33 and / or HDD 34 as an auxiliary storage device, a communication unit 35, a touch panel. , An input unit 36 including a keyboard, keypad, game operation controller, etc., a display unit 37 for performing display display, a speaker for outputting sound, an output unit 38 including a vibrator for outputting vibration, an acceleration sensor, a gyro sensor and other movements The sensor 39 to detect and the bus 40 which bears data communication between these each parts 31-39 are provided.

  The units 1 to 5 of the functional blocks of the information terminal 10 in FIG. 1 can be realized by the CPU 31 that reads a program stored in the ROM 33 and / or the HDD 34 as an auxiliary storage device and executes a predetermined command.

  Note that the hardware configuration of the server 20 can be the same as (or part of) the same as that shown in FIG. Similarly, the units 7 and 8 of the server 20 in FIG. 1 can be realized by the CPU 31 that reads a program stored in the ROM 33 and / or the HDD 34 as an auxiliary storage device and executes a predetermined command.

Hereinafter, the operation of the notification system 30 according to an embodiment will be described. The outline of the processing procedure in this operation is as follows.
[Procedure 1] The reference setting unit 2 sets a reference value for notifying the user.
[Procedure 2] The result acquisition unit 3 acquires the use record of the user.
[Procedure 3] The notification unit 4 notifies the user at a specific timing determined by the timing determination unit 5, or at a predetermined timing desired by the user.

  In the following, details of the processing of each unit in FIG. 1 will be described while describing details of [Procedure 1] to [Procedure 3].

  In addition, as an example of the usage history of the information terminal 10 by the user, a case where the usage time history is acquired and compared with a preset reference value will be mainly described. Similarly, it is possible to obtain a result and notify about other usage modes. An example of performing an evaluation other than the usage time will be described as a supplement as appropriate.

[Procedure 1] Setting of the reference value As described below, the reference value can be either (1) the average value of usage time, (2) the average value of past usage time, or (3) the number of users. Can be set in the reference setting unit 2.

  (1) When the average value of usage time is set as a reference value, the average (group average) usage time of the information terminal 10 in a certain user group for a certain period can be used as the average value.

  For this reason, the achievement acquisition unit 3 in each user's information terminal 10 acquires the usage time for a certain period (for example, the past week), and the usage time for a certain user group (for example, a group of students at a specific school). The results may be collected by the result collection unit 7 in the server 20. The result collection unit 7 obtains the group average of the usage time for the predetermined period and notifies the reference setting unit 2 so that the reference setting unit 2 can set the notified usage time of the group average as a reference value. .

  Here, the usage time may be acquired by the result acquisition unit 3 using various known methods as the time when it is determined that the user is using the information terminal 10. For example, the use time can be acquired as the total time during which the one or more types of predetermined applications (at least one of them) are operating in the foreground by the function of the OS (operating system). Here, the usage time may be acquired for each application type. Further, in addition to the foreground operation for each application type, a user operation (operation on the input unit 36 in FIG. 3) or the like may be added to the determination of the use state. Further, the distinction between application types and the like may be omitted, and the time during which the display (display unit 37) is in the on state (displayed state) may be acquired as the usage time.

  Although the usage time may be defined in various ways as described above, it is preferable to collect the usage time of the common definition for each user when the performance collection unit 7 of the server 20 collects the usage time.

  Also, when the group average is obtained by the performance collection unit 7 of the server 20, the user information of each user is acquired by the information acquisition unit 1 of the information terminal 10, and the users are grouped by the user information collected by the information collection unit 6. The result collecting unit 7 calculates the average for each group, and when notifying the reference setting unit 2 of the information terminal 10 of each user, the average value of the group to which the user belongs may be notified. For example, an average is obtained for each group of “youth” and “working people”, and the user notifies the information terminal 10 of “youth” to the average usage time of the youth. To the information terminal 10 can be notified of the average usage time of members of society.

  User information that is acquired and collected for grouping includes user profiles (age, sex, deviation values related to academic ability, institution, etc.) obtained by the user inputting or selecting for each predetermined item, life Patterns (communication status such as packets, output of acceleration sensor, etc.) can be used.

  In the above user profile, the application download history (that is, the history of applications downloaded and installed on the network so that each user can use them in their own information terminal 10), Information obtained from the history (for example, tag information given in advance for each application (tag information such as a learning application or a sports application)) may be included.

  When the information collecting unit 6 performs grouping, the user profile or the like may be divided according to a preset rule base, or the user information may be converted into a user feature vector and the feature vector Alternatively, a well-known clustering method such as k-means may be applied to separate them. You may make it subdivide further by clustering, after dividing roughly according to a rule base.

  (2) When setting the average value of past usage time as the reference value, the actual acquisition unit 3 acquires the usage time of the user (self) in the past for a certain period, and the average value for the certain unit period Can be obtained as a reference value by obtaining them in the reference setting unit 2. For example, the usage time for the past week can be acquired, and the average value for each day can be used as the reference value. In addition, about acquisition of utilization time, what is necessary is just to acquire by various well-known methods similarly to having demonstrated in said (1).

  (3) When setting the number of users as a reference value, whether the user is using the information terminal 10 from the result acquisition unit 3 of the information terminal 10 of each user in the result collection unit 7 of the server 20 Whether or not it is received in real time and aggregated, and the number of people in use is counted to obtain a reference value. Further, the result collection unit 7 notifies the reference setting unit 2 in each information terminal 10 of each user in real time of the reference value as the number of people in the usage state that is counted in real time, thereby setting the reference value as the reference value.

  It should be noted that “totaling and notifying in real time” above means that the latest values at the present time are totaled and notified at a predetermined rate (for example, every minute or every ten minutes). In order to determine whether or not the performance collecting unit 3 is in use, it may be determined based on whether or not the usage time is acquired in (1) above.

Acquisition of usage record in [Procedure 2] and notification in [Procedure 3] Each of the above (1) to (3) can be acquired and notified as follows. The details of the notification timing and notification contents will be described later.

  (1) When the group average value of usage time is set as a reference value, the actual acquisition unit 3 acquires the actual usage value of the user for a certain period of time similar to the reference value, and the notification unit 4 The user can be notified in the form of enumerating his own results and the reference value as the group average value. In this case, the notification unit 4 generates the optimization promotion information in the form of the listed information. And the information of the said user's own performance will be included as a part (one of the enumerated information) of the optimization promotion information.

  For example, the group average of the usage time of one day (the most recent day) in a certain grade group of a certain school to which the user belongs is one hour, and the user's one day (the most recent day) It is possible to notify that the actual usage time was 2 hours. In this case, by using the property that many people feel uncomfortable that the deviation is larger than the average, the user can be motivated to effectively stop overuse. .

  In addition to notifying the reference value and the actual value in a form of listing, the result of comparing the reference value and the actual value is classified based on a predetermined rule base, and an evaluation result such as “good” or “bad” The optimization promotion information may be generated and notified in the form of In this case, notification may be made visually with an icon representing an expression as described later with reference to FIGS. For example, if the actual value is less than or equal to the reference value, it is determined that the result is “good” and a “smile” icon is displayed. If the actual value is greater than the reference value, the result is determined to be “bad”. Then, the “problem face” icon may be displayed.

  When notification is given to the user of the information terminal 10 in the form of an evaluation result such as “good / bad”, the evaluation result such as “good / bad” is given to the user in advance or at the time of notification. By telling that it is given as a comparative evaluation between the actual value and the reference value, the evaluation result such as “good / bad” functions as the optimization promotion information. (In other words, the user is not only notified of the result of “good / bad” or the like, but is notified including the reason why such a result is obtained.) Also, the optimization in this case The promotion information includes information related to the user's performance in the form of evaluation results such as “good / bad” as in the case of enumerating the above-mentioned results and averages. Separately from the optimization promotion information, the notification unit 4 may notify the user.

  (2) When the average value of usage time in the past fixed period is set as the reference value, the usage time of the most recent unit period is acquired as the actual result by the actual acquisition unit 3, and the actual result of the unit period and the average of the past fixed period Can be generated and notified by the notification unit 4. Also in this case, information on the user's own performance is included in the optimization promotion information.

  In addition, instead of or in addition to generating optimization promotion information in the form listed, it is optimized as information indicating how the performance of the latest unit period has changed with respect to the average of the past fixed period Promotion information may be generated. For example, it may be generated as the optimization promotion information whether the latest result corresponds to “increase”, “decrease”, or “no change” with respect to the past average. It may be determined by applying a predetermined threshold to the difference between the past average and the latest record.

  For example, a certain user is notified that the average daily usage time for the past week has been 1 hour and the most recent daily usage time was 2 hours (ie, You may make it notify that "the last one day use time has increased from the past average" as information which shows a change. By giving the notice that the user is less aware of his / her changes and has a tendency to prevent the usage time from increasing, the notification has increased from the average usage time, It is possible to urge the user to effectively stop overuse.

  In the same way as in the case of (1), in the case of (2), in addition to listing and notifying the past average and the latest results, “good” or based on the comparison result between the past average and the latest results The optimization promotion information may be generated in the form of an evaluation result such as “bad” and notified using a facial expression icon or the like.

  In addition, when making an evaluation judgment by comparing the past average with the latest results, it may be judged on the basis of each group to which the user belongs, and the optimization promotion information may be generated. Here, as for the group to which the user belongs, the user information acquired by the information acquisition unit 1 is aggregated and grouped by the information collection unit 6 in the same manner as described in [Procedure 1] in (1). do it. And based on what totaled the comparison result of the past average of the user who belongs for every group, and the latest performance, you may make it define the criteria of evaluation judgment in each user.

  For example, for each group, the group average of the rate of increase or decrease of the latest results with respect to the past average is obtained, and a “bad” evaluation is given to users showing an increase rate larger than the group average, and “good” is given to users within the group average. May be given.

  (3) When setting the number of users as a reference value, the standard setting unit 2 monitors the number of users in the usage state notified in real time, and the notification unit 4 indicates that the number has been reduced when it is determined that the number of users has decreased. This information can be generated as optimization promotion information and notified to the user. Also in the notification, by making each user aware of the status of other users, as in (1) and (2), the user is encouraged to effectively stop overuse. Can do.

  To determine whether the number of users has decreased, linear fitting (linear fitting on a graph with time on the horizontal axis and the number of users on the vertical axis) is applied to the time change of the number of users over the last fixed period, etc. It may be determined that the slope of the straight line has decreased when the slope of the straight line is negative. In addition, the number of users may be compared with the latest past time, and it may be determined that the number of users has decreased once or when it has decreased for a predetermined number of times. The determination may be performed in the timing determination unit 5.

  In addition, when the notification unit 4 notifies the decrease, it may be notified as text information indicating the decrease, or may be notified with an expression icon such as “problem face”. Further, in the same manner as described in [Procedure 1] in (1) above, based on the result of the user information acquired by the information acquisition unit 1 being aggregated and grouped by the information collection unit 6, the user belongs to You may make it generate and notify the optimization promotion information in the form of the user ratio in a group. For example, the notification may be made in the form of “only 5% of students of the desired school A are currently playing this game”.

  Heretofore, in each of [Procedure 1] to [Procedure 3], the cases where (1) to (3) are used as the reference value and the actual value have been described. Hereinafter, an example of the notification mode by the notification unit 4 and the determination of the notification timing by the timing determination unit 5 that can be applied to each of these cases will be described.

  The notification unit 4 can visually notify using a facial expression icon or the like as a technique for expressing all or part of the optimization promotion information. 4 and 5 are diagrams showing examples of notifications using facial expression icons.

  In FIG. 4, examples of performing notification with a facial expression icon or the like on the screen of the application when acquiring the usage record of the text interaction application between users are shown as [1] and [2]. On the screen D10 in [1], the dialogue sentences S10, S11, S12 and S20, S21 between the users are frequently input, and it is determined that the user is in an overuse state. A mark M10 representing “face” is displayed on the screen D10 by the notification unit 4. In the screen D30 of [2], the dialogue sentences S30, S31, S32 and S40, S41 between the users are not frequently input, and it is determined that the user is not overused. A mark M30 representing “smile” is displayed on the screen D30 by the notification unit 4.

  Here, for example, when the optimization promotion information is generated including the evaluation result in the form of “good” or “bad” described above (two-stage evaluation result), the “smile” corresponding to the expression of the evaluation result respectively. "Or" Frustrated face "mark can be used. Even when evaluation results of three or more levels are used, a mark (such as an expression icon) corresponding to each level can be used.

  As in the example of FIG. 4, when acquiring a usage record for a specific application, the notification unit 4 may make a notification in a form of displaying and / or outputting sound on the screen of the application. Good.

  FIG. 5 shows an example of a screen in the case where reference values are set and results are acquired for various usage results in addition to the usage time, and notifications are given for the respective results. That is, the usage results include the number of hours used (regardless of the type of application), the time zone used (regardless of the type of application), the game usage time (especially the game usage time among the applications), the SNS usage time (application SNS (social networking service usage time)), negative speech (presence / absence), walking smartphone (whether or not the smartphone is operated while walking), and overall evaluation of these, respectively, with facial expression icons Has been notified.

  As for the game usage time and the SNS usage time, it is possible to set the reference value and acquire the results as described above as the usage time after limiting the application type. Regarding the presence or absence of negative utterances, the number of negative words can be made the actual value by a known technique such as referring to a predetermined negative word dictionary or the like for utterances input in an application where the user speaks. The reference value can also be obtained for each group as in the case of usage time. As for the presence or absence of a walking smartphone, a reference value is set in the same manner as in the usage state by monitoring the “walking usage time” that is in the walking state and in the usage state by a well-known method such as analysis of the acceleration sensor output. And achievement acquisition can be performed. The comprehensive evaluation can be obtained as a weighted average of the various evaluation items as described above.

  Next, each embodiment of notification timing determination by the timing determination unit 5 will be described.

  In particular, when the subject to be notified is a game, it is preferable to set a timing appropriate for quitting an enthusiastic game or the like and set it as a notification timing. Basically, the undulations of the user's emotion are estimated from the log information that can be acquired from the information terminal 10 such as a smartphone, etc., and the location where the emotion is easily settled is set as the notification timing. In this case, the timing may be embedded by analyzing the application in advance, or it may be analyzed in real time.

  Hereinafter, a case where the notification timing is determined without depending on the type of application and a case where the timing is determined using a characteristic amount specific to the individual application will be described.

  First, the timing determination unit 5 determines the notification timing by monitoring the feature values that can be collected from general information when handling the information terminal 10 regardless of the type of application for which the reference value is set and notified. Each embodiment is shown. Each embodiment can also be used to suppress long-term use of the information terminal 10 itself regardless of the application type.

  In other words, the following [1] to [5] can be individually monitored as the feature amount or any combination thereof can be monitored to determine the notification timing.

[1] Screen change (pixel value change)
The timing at which the pixel value of the screen (display unit 37 in FIG. 3) changes greatly is likely to be a point when a certain work or the like (application termination, etc.) has been completed, and the user's emotion may have calmed down. high. Therefore, the point in time when the pixel value on the screen changes by a threshold value or more may be determined as the notification timing. It should be noted that the pixel value change may be obtained by a known SAD (sum of absolute differences), SSD (sum of squares of differences), or the like.

[2] Changes in the acceleration sensor, etc. When the acceleration sensor, etc. (sensor 39 in FIG. 9) continues to detect a certain amount of movement, and it is determined that the movement suddenly stops at a certain point in time, the emotions calm down. Therefore, the notification may be made at the determined timing. The presence or absence of movement may be determined as a threshold at each time.

[3] Change in voice Since the timing when the voice calms down is likely to calm down the user's feeling, the timing when the voice calms down may be determined as the notification timing. As for the sound, the power of the sound input to the information terminal 10 by the microphone may be monitored in time series, and the time when the sound is settled by the threshold determination may be detected as in [2] above.

[4] Presence / absence of operation of input device such as touch panel At the timing when the input device (input unit 36 in FIG. 3) is not operated, some operation is completed and it is highly possible that emotions will settle down. can do. Here, it is possible to monitor an input signal corresponding to an input device such as a touch panel or a keypad, and to detect a time when the operation is not performed in the threshold determination and the operation is settled as in [2] and [3].

[5] GPS information and other location information For example, when the user is at home, it is considered that the degree of enthusiasm is higher. Good. That is, a place where there is a high possibility that the user is not settled is registered in advance, and a case where the place is not located can be determined as the notification timing. The position information can be acquired by a known method using GPS (sensor 39 in FIG. 3) or the like.

  As described above, various feature amounts such as [1] to [5] may be used individually, or any combination of these may be used as an input value, and the user's emotion (degree of heat) as an output value. You may make it estimate. In the case of the combination, for example, the output value may be obtained from the input value based on the machine learning relationship established in advance, and the notification timing may be determined, or a combination of individual results in each feature amount based on the rule base. As a result.

  Next, an example in which the notification timing is determined with the feature amount corresponding to the type of the individual application will be described as (1) to (4). When various feature quantities are used in combination, the feature quantity A and the feature quantity B may be used as expanded feature quantities each having a vector element, or the feature quantities A and B may be used respectively. The notification timing may be determined on a rule basis for the entire determined result.

(1) In the case of a game application Although it is possible to detect game milestones and the like based on the screen change described in [1] above, it is also possible to estimate the emotional calming points as follows.

In general, as shown in FIG. 6 and the following, online game players studied in the field of gamification and the like are considered to have four type classifications (personality types). (Richard Bartle)
・ Achiever: There is a strong tendency to feel satisfaction by achieving the goals presented in the game ・ Explorer: Satisfied by making new discoveries about the world in the game ・ Socializer … Prefers friendly relations with other players • Killer… Aims to be superior to other players

  In FIG. 6, the positions of the above four personality types and the description of desirable states in each type are depicted.

Therefore, in each type classification, points at which emotions settle (satisfied points) are extracted from the game.
・ Achiever: When the goal is achieved. When clearing. It may be estimated from the data obtained from the smartphone or the like shown above or embedded in advance so as to output the timing in the game.
・ Explorer: The stage when new elements in the game are released. This may also be estimated from the data obtained from the smartphone shown above or embedded in advance so as to output the timing in the game.
・ Killer: Ranking update, victory. This may also be estimated from the data obtained from the smartphone or the like described above, or embedded in advance so as to output the timing in the game.
・ Socializer: When a friend interrupts the game. This may also be estimated from the data obtained from the smartphone or the like described above, or embedded in advance so as to output the timing in the game.

  Further, the content of the game application may be analyzed in advance to classify the game type. Furthermore, the message when the notification by the notification unit 4 is performed for each type may be changed.

  It should be noted that whether each user corresponds to one of the above types may be determined by acquiring an action in the game in advance and classifying the action on a rule basis. Then, it may be determined on a rule basis from the profile acquired by the information acquisition unit 1 or the like.

(2) In the case of a communication application In the case of a communication application (such as an interactive application or an email in FIG. 4), the notification timing can be determined by a method similar to the method for the socializer in the case of the above game. In addition to this, or instead of this, the contents of communication such as conversation, packet exchanges, etc. are monitored, the calming of both emotions is measured by a well-known method, and the time point when it is determined that it is calm may be used as the notification timing. Specifically, the notification timing is a stage where communication is reduced due to threshold determination, and a stage where the change in content is reduced.

(3) In the case of a moving image application In the case of a moving image, it is possible to estimate a rising point or the like according to the content of a movie or the like, and set a calming point as a notification timing. In addition to the pixel value change, it can be estimated by a well-known method using caption information and comment information (such as Nico Nico Douga (registered trademark)).

(4) In the case of the browser In the case of the browser, it is presumed that the psychology of the explorer and the achievementr in the case of the above game is working. After obtaining some purpose information or after obtaining new information (information that is not in the history), it can be estimated as a calm point and set as a notification timing. For these estimations, the packet communication status or the like may be used. (It is considered that packet communication will decrease after obtaining the target information.) Similarly, as described above, the pixel change of the screen is monitored, and the time point at which it is determined that the change does not occur is used as the notification timing. Good.

  The embodiments of the notification timing have been described above. Note that the notification in the notification unit 4 may be performed by generating a message effective for the user as the optimization promotion information using the method according to the type classification of the user described in FIG. Is possible. For example: The following messages can be used when the achievement acquisition unit 3 acquires game usage results (game play results), but may be used in the same manner for other types of usage results, or otherwise. The corresponding predetermined message may be used in the case of the type of usage record.

・ Achiever: Send a message to remind yourself of your goals (for example, “The study time for people who take the XX university is XX hours”)
・ Explorer: Recall that this type of user can acquire new knowledge because they tend to feel joy in sharing and teaching what they know. Send a message (for example, "Do you know the study time of the person who takes the university?")
・ Killer: Send a message that reminds you of your rivals (for example, “Rival XX is studying XX hours”)
・ Socializer: Send a message to make you aware of the relationship with others (for example, “To go to the same university as Mr. XX, you need to study XX hours on average”)

  Each message as described above is prepared in advance when determining the type of the user from the profile or the like for each type of achievement (for example, game achievement or the like) to be optimized for the user. In addition, the notification unit 4 can generate the information as part of the optimization promotion information. For example, “XX University”, “Rival XXX”, and study time “XX hours” above are based on user profiles (including SNS registration information) acquired by the information acquisition unit 1. Rules may be prepared so that the contents corresponding to the user can be automatically generated on a rule basis.

  Further, the following is also possible as a primary embodiment of the optimization promotion information generated by the notification unit 4. In other words, in the description of [Procedure 2] and [Procedure 3] above, in (1) “When the group average value of usage time is set as the reference value”, the reference values and the results of the users are listed and optimized. Although the embodiment for generating the promotion information has been described, the following may be used instead of or in addition to this.

  That is, grouping and the like are performed in exactly the same way as described above, and the result collection unit 7 acquires the distribution of the actual value of the usage time for each user in the group to which the user belongs, and the notification unit 7 The optimization promotion information may be generated as information expressing the position of the actual value in the distribution of the entire group. For example, with regard to usage time, the usage time of all users belonging to the group is aggregated, and the content such as the ranking in which the usage time of the user is higher (higher in a bad sense) is higher. Optimization promotion information can be generated.

  For example, if the user is in the top 20% of users in the group who are long-time users (that is, users who are using inappropriate long time and want to improve) It can be generated as promotion information. In combination with the above message, for example, “of the university students taking the exam, your smartphone usage time is the longest 20% use time.” It may be generated. In this case, the information collection unit 6 of the server 20 may identify the group “XX university student” to which the user belongs.

  It should be noted that optimization promotion information is generated not only for the usage time but also for other general usage results in the form of expressing the position of the user's performance in the distribution of the usage results within the group to which the user belongs. be able to. In addition, when the optimization unit generates the promotion information in the notification unit 4 in the form of positioning the actual value within the group distribution, the standard setting unit 2 instead of setting the standard value as the average value or the like, The distribution information may be passed directly to the notification unit 4 (after being received from the result collection unit 7 of the server 20), or the distribution within the group may be expressed concisely and the ranking of the user's usage results may be simplified. As information for obtaining, a predetermined quantile or the like may be set as a reference value.

  Next, another embodiment using the timing determination unit 5 will be described. That is, the timing determination unit 5 can determine the time point when it is determined that the user has settled according to each of the embodiments described above. Therefore, at the time of the determination, the notification unit 4 instead of or in addition to notifying the user of the optimization promotion information and the usage record as described above, the predetermined information is sent to the user. You may make it notify. This is because the user is calm at the time of the determination, and notification of the predetermined information is considered to be effectively realized.

  As an example of notification of the predetermined information, application recommendation (application recommendation) suitable for the user may be performed. The application recommendation can be performed in a text or other multimedia format, for example, in a format in which a web page with a predetermined URL is presented by a browser executed on the information terminal 10. Here, the web page may be configured to include the location information of the file of the recommended application so that the recommended application can be installed in the information terminal 10.

  In addition, about the application suitable for the said user, according to the said user's profile etc. which the information acquisition part 1 acquires, and / or the said user's utilization track record acquired by the track record acquisition part 3, predetermined 1 on a rule base The above applications may be automatically determined. Here, an application to be recommended may be prepared for each group to which the user belongs, which is determined as described above based on the collection information of the information collection unit 6 of the server 20. For example, in the case of an examinee group, an application related to study may be prepared as a recommendation target.

  As described above, according to the present invention, the use of smartphones and other information terminals 10 can be optimized by performing notification using a psychology that the user wants to stay on average (not to deviate greatly from the average from many people). Can do. In particular, long-term use of adolescent smartphones can be prevented.
