Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Outline of information processing system)
An outline of an information processing system 1 according to an embodiment of the present invention will be described with reference to FIG. The information processing system 1 includes an information processing device 10 and a plurality of terminal devices 20. The information processing device 10 is, for example, a server device, but is not limited to this, and may be any device having an information processing function. Further, the information processing device 10 according to the present embodiment may be replaced with a plurality of devices that can communicate with each other. The terminal device 20 is, for example, an electronic device such as a PC (Personal Computer) or a smartphone, but is not limited to these and may be any device used by the user. Although only three terminal devices 20 are shown in FIG. 1 for simplicity of explanation, the information processing system 1 may include any number of terminal devices 20.

The information processing device 10 and the terminal device 20 can communicate with each other via a network 30 including a mobile communication network and the Internet, for example. The information processing device 10 can communicate with a node on a distributed network (hereinafter, referred to as a block chain network) that stores a distributed ledger (for example, a block chain), or the information processing device 10 itself blocks. Functions as a node on the chain network. Alternatively, for example, as shown in FIG. 9, each of the information processing device 10 and the terminal device 20 may function as a node on the block chain network.

First, an outline of this embodiment will be described, and details will be described later. The information processing device 10 provides a user with a service using cryptographic assets. The crypto asset is, for example, a virtual currency or a crypto token, but is not limited to these. Cryptographic assets may be managed, for example, in a client-server model system or on a distributed network (eg, using blockchain). The user receives the service by transmitting the account information (that is, the login ID, the password, and the like) to the information processing device 10 by using the terminal device 20 and logging in. The service is, for example, a posting function for a user to post content such as an article, an evaluation function for another user to evaluate the posted content, and a cryptographic asset for giving a cryptographic asset to the poster and the evaluator of the content. The asset providing function is provided, but the present invention is not limited to these and may have an arbitrary function. Hereinafter, posting and evaluation of content will be referred to as “activity” without distinction.

In the present embodiment, the information processing apparatus 10 has, for each user, the number of cryptographic assets held, the first parameter t (hereinafter, referred to as “temperature t”), and the first function v(t) having the temperature t as arguments. User information including a second parameter a indicated by (hereinafter, referred to as “validation ratio a”), a score, and the like is stored. As will be described later, the temperature t is, for example, a parameter that changes with the passage of time, but may be any parameter that requires time for its value to change. Further, the temperature t changes, for example, in the range of −50≦t≦50. When the user carries out an activity (that is, posting or evaluation of content), the score of the user increases based on the number obtained by multiplying the possession number of the cryptographic asset of the user by the activation ratio a. Then, the cryptographic asset is given to the user based on the score of the user.

Here, a non-linear function is used as the first function v(t). Specifically, the first function v(t) decreases with an increase in the temperature t in a range that the temperature t can take (that is, −50≦t≦50), and the range is at the center and both sides thereof. When divided into three small ranges, the small ranges on both sides (for example, −50≦t<−25, and 25<t≦50) are smaller than the central small range (for example, −25≦t≦25). The feature is that the temperature changes gently with respect to the temperature t.

With this configuration, it is possible to promote the fixation of users who use the service. That is, in the present embodiment, the score is increased based on the number obtained by multiplying the number of possessed cryptographic assets of the user by the activation ratio a, and the cryptographic asset is given to the user based on the score, with the implementation of the activity as a trigger. It Therefore, it is desirable for the user who wants to acquire the cryptographic assets to actively carry out the activity and increase the activation ratio a. As described above, the activation rate a is represented by the first function v(t) with the temperature t that requires time for the value to change as an argument. Here, for example, consider that the temperature t decreases with the passage of time. When the temperature t is around t=50, the activation ratio a does not easily change from a small value over time, but when the temperature t drops to around t=0 over time, On the other hand, the activation rate a increases sharply. Then, when the temperature t drops to around t=−50 over a longer period of time, the activation rate a becomes difficult to change from a large value. Therefore, the user can be motivated to continue the activity for a long period of time, so that the fixation of the user who uses the service can be promoted.

Next, the information processing device 10 included in the information processing system 1 will be described in detail.

As shown in FIG. 2, the information processing device 10 includes a communication unit 11, a storage unit 12, and a control unit 13.

The communication unit 11 includes a communication module connected to the network 30. The communication module corresponds to, for example, a wired LAN (Local Area Network) standard, but is not limited to this and may correspond to any communication standard. In the present embodiment, the information processing device 10 is connected to the network 30 via the communication unit 11.

The storage unit 12 includes one or more memories. In the present embodiment, the “memory” is, for example, a semiconductor memory, a magnetic memory, an optical memory, or the like, but is not limited to these. Each memory included in the storage unit 12 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 12 stores arbitrary information used for the operation of the information processing device 10.

In the present embodiment, the storage unit 12 stores user information for each user. The user information is, for example, as shown in FIG. 3, a user ID, wallet information, the number of cryptographic assets held, a temperature t (first parameter t), an activation ratio a (second parameter a), and a withdrawal. It includes, but is not limited to, the possible ratio b (third parameter b), the score, and the change mode, and may include arbitrary information about the user, such as account information.

The user ID is information that can uniquely identify the user in the service provided by the information processing device 10.

The wallet information is information about a wallet that manages cryptographic assets owned by the user. In this embodiment, the wallet is an online wallet or a web wallet. For example, the wallet information may include a private key, a public key, and a wallet address. The private key and public key are used when transmitting a transaction request for cryptographic assets to a node on the blockchain network. The wallet address is information designated as a transfer source or transfer destination when moving the cryptographic asset.

The number of crypto assets held is the number of crypto assets held by the user in the wallet. Here, the “number” of cryptographic assets may be represented by an integer or a decimal.

The temperature t is a parameter of a first function v(t) and a second function l(t) described later. In the present embodiment, the possible range of the temperature t is −50≦t≦50. However, the range that the temperature t can take is not limited to this. The range of temperature t may be defined in advance. The temperature t is controlled so as not to deviate from the above range (−50≦t≦50). The initial value of the temperature t is, for example, t=−50, but is not limited to this and may be set arbitrarily. The temperature t is a parameter that requires time for its value to change. In other words, the temperature t is a parameter indicated by a function that takes time itself as an argument or a function that takes an arbitrary variable that requires time to change its value as an argument. Specifically, the temperature t may be a parameter that changes with time. In such a case, the temperature t may change every time a predetermined time elapses, or may change in real time. Further, specifically, the temperature t is the number of evaluations (for example, the number of so-called “likes”) from other users with respect to the content posted by the user, the centrality in the social network (for example, eccentricity centrality, closeness centrality). , Or eigenvector centrality), or a parameter that changes according to Pagerank or the like. In the present embodiment, as will be described later, the temperature t is exemplarily described as being controlled so as to change every time a predetermined time (for example, one day) elapses. In addition, in the present embodiment, it is assumed that the user cannot directly operate, specify, or change the value of the temperature t.

ここでαは、調整パラメータであって、例えば０．０３であるが任意に定められてもよい。式（１）によれば、有効化割合ａは、例えば図４に示すように、温度ｔが低下するほど増加し、ｔ＝−５０において有効化割合ａは１（すなわち、１００％）となる。しかしながら、第１関数ｖ（ｔ）は上記の式（１）に限られない。例えば、第１関数ｖ（ｔ）は階段関数であってもよい。 The activation ratio a is a parameter represented by the first function v(t) having the temperature t as an argument. The activation rate a is used when increasing the score of the user as described later. Specifically, the score of the user increases based on the number obtained by multiplying the number of possessed cryptographic assets of the user by the activation ratio a. The first function v(t) is a non-linear function, decreases with an increase in the temperature t in a range of the temperature t (that is, −50≦t≦50), and the range is at the center and both sides thereof. When divided into three small ranges, the smaller range on both sides (for example, -50≦t<-25, and 25<t≦50) is smaller than the central small range (for example, −25≦t≦25). However, it changes gently with respect to the change of the temperature t. In the present embodiment, the following expression (1) is adopted as the first function v(t).

Here, α is an adjustment parameter and is, for example, 0.03, but may be arbitrarily set. According to the equation (1), the activation rate a increases as the temperature t decreases, as shown in FIG. 4, for example, and the activation rate a becomes 1 (that is, 100%) at t=−50. .. However, the first function v(t) is not limited to the above equation (1). For example, the first function v(t) may be a step function.

ここでｎは、ユーザが保有する全暗号資産を引出すのに必要な引出操作の最大回数（すなわち、ｔ＝−５０の状態でユーザが全保有暗号資産を引出すのに必要な引出操作の回数）であり、例えば１３であるが任意に定められてもよい。式（２）によれば、引出可能割合ｂは、例えば図５に示すように、温度ｔが上昇するほど増加し、ｔ＝５０において引出可能割合ｂは１（すなわち、１００％）となる。しかしながら、第２関数ｌ（ｔ）は上記の式（２）に限られない。例えば、第２関数ｌ（ｔ）は階段関数であってもよい。 The drawable ratio b is a parameter represented by the second function l(t) having the temperature t as an argument. The withdrawable ratio b is used when the withdrawal process of the cryptographic assets held by the user is executed as described later. More specifically, the upper limit number of withdrawals is determined by multiplying the number of cryptographic assets held by the user by the withdrawable ratio b. The second function l(t) is a non-linear function, and increases with an increase in the temperature t in the range that the temperature t can take (that is, −50≦t≦50), and the temperature t is the same in the range. The closer to the upper limit value (ie, 50) of the range, the more rapidly it changes with respect to the change of the temperature t. In the present embodiment, the following equation (2) is adopted as the second function l(t).

Here, n is the maximum number of withdrawal operations required to withdraw all cryptographic assets owned by the user (that is, the number of withdrawal operations required for the user to withdraw all cryptographic assets possessed at t=-50). And, for example, 13 but may be arbitrarily determined. According to the formula (2), the drawable ratio b increases as the temperature t increases, and the drawable ratio b becomes 1 (that is, 100%) at t=50, as shown in FIG. 5, for example. However, the second function l(t) is not limited to the above equation (2). For example, the second function l(t) may be a step function.

The score is a parameter that increases as a user performs an activity. The initial value of the score is, for example, 0, but is not limited to this and may be set arbitrarily. Specifically, when the user performs the activity, the score increases based on the number of the possessed cryptographic assets of the user multiplied by the activation rate a. As will be described later, the score is used when giving a cryptographic asset to the user.

ここでｄは、ユーザが暗号資産を引出可能な機会のインターバル日数であり、例えば７日であるが任意に定められてもよい。 The change mode is a parameter used when changing the temperature t over time. In the present embodiment, one of the first mode (hereinafter referred to as “cooling mode”) and the second mode (hereinafter referred to as “heating mode”) is used as the change mode. The change mode can be switched between the cooling mode and the heating mode in response to a request from the user's terminal device 20, for example. The initial setting of the change mode is, for example, the cooling mode. When the change mode is the cooling mode after the predetermined time (for example, one day) elapses as described above, the temperature t decreases by the temperature change amount Δt represented by the following formula (3), while the change mode changes. In the heating mode, the temperature t increases by the temperature change amount Δt.

Here, d is the interval number of days when the user can withdraw the cryptographic asset, and is, for example, 7 days, but may be arbitrarily determined.

The control unit 13 illustrated in FIG. 2 includes one or more processors. In the present embodiment, the “processor” is a general-purpose processor or a dedicated processor specialized for specific processing, but is not limited to these. The control unit 13 has a timekeeping function for grasping the current time. The control unit 13 controls the operation of the entire information processing device 10.

For example, the control unit 13 carries out a process for realizing the above-described posting function and evaluation function. Specifically, the control unit 13 accepts posting of content from the user's terminal device 20. The content may include, for example, text data, image data, video data, and/or music data, but is not limited thereto. The control unit 13 stores the content received from the terminal device 20 via the network 30 in the storage unit 12 and publishes the content via the network 30. Alternatively, the control unit 13 may store the content in the block chain. The content disclosure target may be limited to the user who has logged in to the service, or may be any terminal device 20 connectable to the network 30. The control unit 13 also receives an evaluation of the content from the terminal device 20 of the user who browsed the published content. The evaluation of the content may include, for example, setting a flag indicating an impression of the content (for example, adding a so-called “like” or the like), and scoring the content (for example, any one of −5 to 5 points). May be included, or posting a comment for the content may be included. As described above, in the present embodiment, the control unit 13 receives two activities of content posting and evaluation.

Other typical operations of the information processing device 10 controlled by the control unit 13 will be described with reference to FIGS. 6 to 8.

FIG. 6 is a flowchart showing the first operation of the information processing device 10 controlled by the control unit 13. As a summary, the first operation is an operation of changing the temperature t of the user. As described above, the temperature t is a parameter that requires time to change its value, but here, as a specific example, the temperature t of the user is changed every time a predetermined time (for example, one day) elapses. The configuration will be described.

Step S100: The control unit 13 stores the user information in the storage unit 12 for each user. As described above, the user information includes, for example, the user ID, the wallet information, the number of cryptographic assets held, the temperature t (first parameter t), the activation rate a (second parameter a), and the withdrawable rate. b (third parameter b), a score, and a change mode are included.

Step S101: The control unit 13 determines whether or not a predetermined time (for example, one day) has elapsed. In detail, the control unit 13 may determine whether or not a predetermined time has passed from a predetermined time (for example, 00:00), or a predetermined time from a timing when the predetermined time has been finally determined. It may be determined whether or not time has elapsed. If it is determined that the predetermined time has not elapsed (step S101-No), the process repeats step S101. On the other hand, if it is determined that the predetermined time has elapsed (step S101-Yes), the process proceeds to step S102.

Step S102: The control unit 13 changes the temperature t of each user. Specifically, the control unit 13 decreases or increases the temperature t of the user according to the change mode of the user. In the present embodiment, when the user's change mode is the cooling mode, the control unit 13 reduces the temperature t by the temperature change amount Δt described above (that is, t=t−Δt). On the other hand, when the change mode of the user is the heating mode, the control unit 13 increases the temperature by the temperature change amount Δt (that is, t=t+Δt). After that, the process returns to step S101.

FIG. 7 is a flowchart showing the second operation of the information processing device 10 controlled by the control unit 13. As a summary, the second operation is an operation of increasing the score of the user when the user carries out an activity and giving the user a cryptographic asset based on the score.

Step S200: The control unit 13 determines whether or not the user has performed a predetermined activity (that is, content posting or evaluation) in the service. For example, when the control unit 13 accepts posting or evaluation of content from the user's terminal device 20, the control unit 13 determines that the user has performed the activity. If it is determined that the user has not performed the activity (step S200-No), the process proceeds to step S202. On the other hand, if it is determined that the user has performed the activity (step S200-Yes), the process proceeds to step S201.

Step S201: The control unit 13 increases the score of the user based on the value obtained by multiplying the number of possessed cryptographic assets of the user by the activation rate a. Specifically, the control unit 13 greatly increases the score of the user as the value obtained by multiplying the possession number of cryptographic assets by the activation rate a is larger.

Step S202: The control unit 13 determines whether or not the score collection period (for example, one week) has expired. Specifically, the control unit 13 may determine whether or not the score tabulation period has expired starting from a predetermined time (for example, 00:00 on Sunday), or that the score tabulation period has expired. It may be determined whether or not the new score tabulation period started from the timing of the final determination has expired. When it is determined that the score tabulation period has not expired (step S202-No), the process returns to step S200. On the other hand, when it is determined that the score tabulation period has expired (step S202-Yes), the process proceeds to step S203.

Step S203: The control unit 13 gives a cryptographic asset to the user based on the score of the user. Specifically, the control unit 13 gives more cryptographic assets to the user as the score of the user is higher. The cryptographic asset is given by, for example, transmitting a transaction request for adding the cryptographic asset to the user's wallet to a node on the blockchain network.

Step S204: The control unit 13 resets the score of the user (that is, returns it to the initial value). Thereafter, the process returns to step S200.

FIG. 8 is a flowchart showing a third operation of the information processing device 10 controlled by the control unit 13. As a summary, the third operation is an operation of setting the upper limit number of withdrawal of cryptographic assets and executing withdrawal processing of the possessed cryptographic assets of the user when the user performs the withdrawal operation of the possessed cryptographic assets.

Step S300: The control unit 13 determines whether or not the user has performed a withdrawal operation of the possessed cryptographic assets. For example, when the control unit 13 receives the withdrawal request for the possessed cryptographic assets from the terminal device 20 of the user, the control unit 13 determines that the user has performed the withdrawal operation. When it is determined that the drawing operation is not performed (step S300-No), the process repeats step S300. On the other hand, when it is determined that the drawing operation has been performed (step S300-Yes), the process proceeds to step S301.

Step S301: The control unit 13 carries out the withdrawal process of the possessed cryptographic assets, with the withdrawal upper limit number being the number obtained by multiplying the number of possessed cryptographic assets of the user by the withdrawable ratio b. In detail, the control unit 13 moves a transaction from one wallet to another wallet, based on a withdrawal request from the user's terminal device 20, the number of cryptographic assets specified by the user or the withdrawal upper limit number, whichever is smaller. Send the request to a node on the blockchain network. Thereafter, the process returns to step S300.

As described above, the information processing apparatus 10 according to the embodiment includes, for each user, user information (for example, the number of cryptographic assets held, the temperature t that requires time for the value to change, the first function v(t). ) Is stored, the temperature t of the user is changed, and when the user performs a predetermined activity in the service, the activation ratio a is stored in the number of cryptographic assets held by the user. The score of the user is increased based on the multiplied number, and the cryptographic asset is given to the user based on the score of the user. Here, the first function v(t) decreases with an increase in the temperature t in a possible range of the temperature t, and when the range is divided into the center and three small ranges on both sides of the range, the small value at the center is small. The small ranges on both sides of the range change more gently with respect to changes in the temperature t.

With this configuration, it is possible to promote the fixation of users who use the service. That is, in the present embodiment, it is desirable for a user who wants to acquire a cryptographic asset to actively perform the activity and increase the activation rate a. As described above, the activation rate a is represented by the first function v(t) with the temperature t that requires time for the value to change as an argument. Here, for example, consider that the temperature t decreases every time a predetermined time elapses. When the temperature t is around t=50, the activation ratio a does not easily change from a small value over time, but when the temperature t drops to around t=0 over time, On the other hand, the activation rate a increases sharply. Then, when the temperature t drops to around t=−50 over a longer period of time, the activation rate a becomes difficult to change from a large value. Therefore, it is possible to give the user motivation to continue the activity for a long period of time, and it is possible to promote the retention of the user who uses the service. Therefore, the technology related to services using cryptographic assets is improved.

Further, the information processing apparatus 10 according to the embodiment of the present invention further stores the withdrawable ratio b indicated by the second function l(t) for each user, and when the user performs the withdrawal operation of the possessed cryptographic assets. , The withdrawal processing of the possessed cryptographic assets is performed with the number obtained by multiplying the possessed number of the cryptographic assets of the user by the withdrawable ratio b as the withdrawal upper limit number. Here, the second function l(t) increases with the increase of the temperature t in the range of the temperature t, and the temperature t changes as the temperature t approaches the upper limit of the range in the range. On the other hand, it changes rapidly.

With such a configuration, it is possible to reduce the risk that a user who is active in the service, such as a user who continues activity for a long time, quits using the service. That is, when the user quits using the service, it is conceivable to withdraw the possessed cryptographic assets, for example, in order to dispose of the possessed cryptographic assets at an external exchange to make a profit. On the other hand, a beneficial user who continues the activity for a long period of time is considered to have a relatively low temperature t in order to obtain more crypto assets as the activity is performed. In other words, it is suggested that a user who has a low temperature t and who holds a lot of crypto assets is a user who is useful for activating the service. Therefore, according to the configuration using the withdrawable ratio b described above, the lower the temperature t, the smaller the ratio of the cryptographic assets that can be withdrawn at one time, and thus the risk that a user useful for activating the service may quit using the service. Is reduced. For this reason, the technology relating to services using cryptographic assets is further improved.

Although the embodiments of the present disclosure have been described with reference to the drawings, it should be noted that those skilled in the art can easily make various variations or modifications based on the present disclosure. Therefore, it should be noted that these variations or modifications are included in the scope of the present disclosure. For example, the functions and the like included in each means or each step can be rearranged so as not to logically contradict. For example, it is possible to combine or divide a plurality of means or steps into one.

For example, in the above-described embodiment, a user who has a low temperature t and who holds many cryptographic assets is highly likely to be a user who is useful for activating the service, such as continuing the activity for a long period of time. In other words, the low temperature t and the large number of possession of cryptographic assets means that the user is highly reliable as a useful user. However, it is also assumed that the user acquires the cryptographic assets through a route other than the activity execution, such as purchasing the cryptographic assets using an external exchange. In such a case, the reliability that a user who has a large number of cryptographic assets is a useful user is deteriorated.

On the other hand, in another embodiment of the present invention, when the user acquires the cryptographic asset, the temperature t is changed according to the acquisition route. Specifically, when the user acquires the cryptographic asset, the control unit 13 of the information processing apparatus 10 has the cryptographic asset assigned by the information processing apparatus 10 (that is, the cryptographic asset assigned by the activity). Or not.

ここで、Ａはユーザの暗号資産の現在の保有数であり、ΔＡはユーザに付与された暗号資産の数であり、ｔは変化前の温度であり、ｔ´は変化後の温度である。また、関数ｖ^-1（ａ）は、第１関数ｖ（ｔ）の逆関数である。 When it is determined that the cryptographic asset is given by the information processing apparatus 10, the control unit 13 reduces the temperature t of the user. For example, the control unit 13 reduces the temperature t of the user based on the following equation (4).

Here, A is the current number of cryptographic assets owned by the user, ΔA is the number of cryptographic assets given to the user, t is the temperature before the change, and t′ is the temperature after the change. The function v ^-1 (a) is the inverse function of the first function v(t).

ここで、関数ｌ^-1（ｂ）は、第２関数ｌ（ｔ）の逆関数である。かかる構成によれば、例えば外部の取引所を利用して暗号資産を購入したユーザは、購入により暗号資産の保有数が多くなる一方で温度ｔが高くなるので、誤って当該ユーザが有益なユーザであると直ちに判断される蓋然性が低下する。 On the other hand, when the control unit 13 determines that the cryptographic asset is not assigned by the information processing apparatus 10, the control unit 13 increases the temperature t of the user. For example, the control unit 13 increases the temperature t of the user based on the following equation (5).

Here, the function l ^-1 (b) is an inverse function of the second function l(t). According to such a configuration, for example, a user who purchases a cryptographic asset using an external exchange increases the number of cryptographic assets held by the purchase, but the temperature t becomes high. The probability of being immediately judged to be lower decreases.

Further, in the above-described embodiment, the configuration in which the score is reset when the score collection period expires has been described. However, the storage unit 12 of the information processing device 10 may store the “score integrated value” as the user information. In such a case, for example, when resetting the score, the control unit 13 resets the score by adding the score to the score integrated value. A user with a high score integration value is highly likely to be a user who is useful for activating the service such as continuing the activity for a long time. Therefore, the score integrated value can be used as an index of whether or not the user is a useful user.

Further, in the above-described embodiment, the range in which the temperature t can be −50≦t≦50 (here, referred to as the first range) has been described as an example. However, the range of the temperature t may be set arbitrarily. For example, the range that the temperature t can take is −100≦t≦200(
Here, it is referred to as the second range. ) Or the like. In such a case, the range that the temperature t can take is the second range, but the above-described embodiment is applicable to the first range that is at least a part of the second range. In other words, if the above-described embodiment is applied to the first range, the parts other than the first range in the second range may not be applied.

Further, in the above-described embodiment, the configuration has been described in which, when the user performs the activity in the service, the score of the user is increased. Here, for example, the increase amount of the score may be different depending on the type of the performed activity (for example, posting or evaluation of the content). Further, in the above-described embodiment, two activities of content posting and evaluation have been described. However, there may be more than two activities depending on the content of the service. For example, services such as browsing content posted by a user, registration of service use (that is, account creation), single-play or multi-play of a predetermined game, execution or download of a predetermined application program, or account linkage with an external service. It is also possible to treat any activity that can be performed by the user as an “activity” through.

Further, in the above-described embodiment, the example in which the wallet for managing the cryptographic assets is the online wallet or the web wallet has been described. However, the wallet may be, for example, a desktop wallet or a mobile wallet. In such a case, the terminal device 20 may store the wallet information instead of the information processing device 10, and the information processing device 10 may receive the information on the number of cryptographic assets held from the terminal device 20.

Further, in the above-described embodiment, the two modes, that is, the first mode (cooling mode) and the second mode (heating mode), have been described as the user change modes. However, there may be more than two change modes. For example, there may be a third mode (hereinafter, referred to as “temperature maintaining mode”) in which the user's temperature t is controlled so as not to change. Specifically, the control unit 13 of the information processing device 10 controls the temperature t of the user so as not to change with the passage of time while the change mode of the user is the temperature maintenance mode.

As the information processing device 10 according to the above-described embodiment, any information processing device such as a general-purpose computer can be adopted. For example, a program that describes the processing content that realizes each function of the information processing device 10 according to the embodiment is stored in the memory of the device and is executed by the processor of the device. Therefore, the embodiment of the present invention can be realized as a program.
