Description

[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing system. [Background technology]

[0002] Systems are known that allow users to send and receive messages with others using communication terminals such as smartphones or tablets (see, for example, Patent Document 1). Communication terminals that allow users to send and receive messages are becoming popular among the elderly, and the number of elderly people using such systems to send and receive messages is increasing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7043665 Summary of the Invention [Problem to be solved by the invention]

[0004] It is believed that users of communication devices can maintain and improve their cognitive function by sending and receiving messages using the device. In particular, there is a possibility that the act of teaching something to others can lead to a protégé effect, which deepens understanding of what has been taught, and improve cognitive function. Therefore, sending and receiving messages using communication devices by elderly people can help improve their cognitive function.

[0005] However, many users of communication terminals find it troublesome to operate a communication terminal to send a message, and therefore there is a need to increase the motivation of communication terminal users to send messages.

[0006] The present invention has been made in view of these points, and has as its object to motivate users of communication terminals to send messages. [Means for solving the problem]

[0007] An information processing device according to a first aspect of the present invention is an information processing device that sends a message to a communication terminal, and includes a message sending unit that sends a character message including erroneous text in which part of normal text is an error to the communication terminal, and a message receiving unit that receives a user message from the communication terminal including the normal text corresponding to the erroneous text after the message sending unit sends the character message to the communication terminal.

[0008] The information processing device may further have a memory unit that stores one or more erroneous texts, each having an error, in association with a plurality of the normal texts, and the message sending unit may send the character message including the erroneous text associated in the memory unit with the normal text selected from the plurality of normal texts stored in the memory unit.

[0009] The message sending unit may input the normal text to be included in the character message to a machine learning model that outputs the incorrect text when the normal text is input, and then send the character message including the incorrect text output from the machine learning model.

[0010] The message sending unit may send the character message including the regular text corresponding to the sent erroneous text after the message receiving unit receives the user message including the regular text corresponding to the erroneous text.

[0011] After the message receiving unit receives the user message including the normal text corresponding to the erroneous text, the message sending unit may send the character message including the erroneous text that corresponds to the normal text included in the received user message and that is different from the erroneous text that was sent.

[0012] The message sending unit may resend the character message including the erroneous text when the message receiving unit does not receive the user message including the regular text corresponding to the erroneous text.

[0013] The message sending unit may not send the character message including the second erroneous text different from the first erroneous text until a predetermined period of time has elapsed since the message receiving unit received the user message including the normal text corresponding to the first erroneous text, and may send the character message including the second erroneous text after the predetermined period of time has elapsed.

[0014] The storage unit may store the regular text, the erroneous text, and the genre to which the noun represented by the regular text belongs in association with each other, and the message sending unit may send the character message including a second erroneous text associated with a genre different from the genre associated with the first erroneous text after a predetermined period of time has elapsed since sending the character message including a first erroneous text.

[0015] The erroneous text may be text in which two adjacent characters among a plurality of characters included in the normal text are swapped, or text in which one or more characters among a plurality of characters included in the normal text are swapped with a character that has the same vowel as the vowel of the character but a different consonant.

[0016] The message sending unit sends audio data of the character message, and the audio data may be audio data in which clear sounds included in the regular text are replaced with voiced sounds, audio data that is pronounced faster than the audio data corresponding to the regular text, or audio data that is pronounced quieter than the audio data corresponding to the regular text.

[0017] When the message receiving unit receives the user message including the correct text corresponding to the erroneous text, the message sending unit may send the character message including text expressing gratitude.

[0018] The information processing device may further have an image generation unit that generates a character image, and the message sending unit may send the character message including the erroneous text together with a first character image, and after the message receiving unit receives the user message including the correct text corresponding to the erroneous text, may send the character message including a second character image obtained by changing a part of the first character image.

[0019] The memory unit may further store scenario data in which a stage of progress and a situation are associated, and the message sending unit may, after sending a first character message including a first erroneous text associated with a first stage of progress indicated by the scenario data, send a second character message including a second erroneous text associated with a second stage of progress that is the next stage of the first stage of progress.

[0020] A second aspect of the information processing method of the present invention is an information processing method for a computer to send a message to a communication terminal, in which the computer performs the steps of sending a character message including erroneous text in which part of normal text is erroneous to the communication terminal, and after sending the character message to the communication terminal, receiving a user message from the communication terminal including the normal text corresponding to the erroneous text.

[0021] An information processing system of a third aspect of the present invention comprises a communication terminal and an information processing device that sends a message to the communication terminal, wherein the information processing device has a message sending unit that sends a character message including erroneous text in which part of normal text is an error to the communication terminal, and a message receiving unit that receives a user message from the communication terminal including the normal text corresponding to the erroneous text after the message sending unit sends the character message to the communication terminal, and the communication terminal has a display unit that displays the character message. [Effects of the Invention]

[0022] The present invention has the effect of motivating users of communication terminals to send messages. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0024] [Outline of Information Processing System S] 1 is a diagram illustrating an overview of an information processing system S. The information processing system S includes an information processing device 1 and a communication terminal 2. The information processing device 1 and the communication terminal 2 can send and receive chat messages to and from each other via a network N. The communication terminal 2 accesses the network N via, for example, a wireless communication line.

[0025] The communication terminal 2 is, for example, a smartphone or a tablet, and has a display that is a display unit that can display messages received from the information processing device 1. The communication terminal 2 also has a touch panel that is an operation unit that allows a user U who uses the communication terminal 2 to input messages. In this specification, a message of a virtual character transmitted by the information processing device 1 is referred to as a character message, and a message input by the user U and transmitted by the communication terminal 2 is referred to as a user message.

[0026] The communication terminal 2 displays the character messages and the user messages in chronological order. The communication terminal 2 displays the character messages received from the information processing device 1 in association with at least one of the name of the character or the image of the character generated by the information processing device 1, and displays the user messages in association with at least one of the user name or the image of the user.

[0027] The information processing device 1 is a computer capable of communicating with a plurality of communication terminals 2 used by a plurality of different users U. The information processing device 1 is, for example, a server managed by a provider that provides a chat service, and causes the communication terminal 2 to display a chat screen including character messages and user messages. The information processing device 1 causes the communication terminal 2 to display the character messages by transmitting the character messages to the communication terminal 2. Details will be described later, but the information processing device 1 sequentially creates character messages according to a predetermined scenario, for example.

[0028] The information processing device 1 generates a character message uttered by a virtual character. The information processing device 1 generates a character message whose content corresponds to the content of a user message transmitted by the user U. The information processing device 1 transmits the generated character message to the communication terminal 2. The information processing device 1 may transmit the character message to the communication terminal 2 together with a character image showing the character's face. For example, the information processing device 1 transmits the character message together with an image of a character selected by the user U from a plurality of character images generated in advance.

[0029] The information processing device 1 has a function of transmitting a character message including text of an incorrect word (hereinafter referred to as "incorrect text") to the communication terminal 2. The information processing device 1 may transmit a character message including incorrect text at any timing, but conditions for transmitting a character message including incorrect text may be determined in advance. A condition for transmitting a character message including incorrect text may be, for example, that a predetermined period (e.g., one day or more) has passed since the previous transmission of incorrect text. A condition for transmitting a character message including incorrect text may also be that no user message has been transmitted from the user U for a predetermined period (e.g., one week or more).

[0030] Fig. 2 is a diagram showing an example of messages being sent and received between a character and a user U. Fig. 3 is a diagram showing examples of character messages and user messages displayed on the communication terminal 2. In the example shown in Fig. 2, messages sent by the information processing device 1 are displayed above the communication terminal 2, and user messages input by the user U to the communication terminal 2 are displayed below the user U. In Fig. 3, messages with facial images displayed on the left side are character messages, and messages with facial images displayed on the right side are user messages.

[0031] First, the information processing device 1 sends a character message "I'll put on some ketchup," which includes the erroneous text "Kepatchu." User U, seeing this character message, inputs a user message "It's ketchup," which includes the correct text (hereinafter referred to as "regular text") that corrects the erroneous text and tells the character that "Kepatchu" is incorrect.

[0032] After receiving a user message containing normal text, the information processing device 1 transmits a character message "Yes, kechatchu" containing erroneous text "kechatchu" that is different from the previously transmitted erroneous text. In response to this, the user U inputs a user message "So, it's ketchup," which contains the normal text "ketchup," to inform the character that "kechatchu" is incorrect.

[0033] In this way, when the information processing device 1 transmits to the communication terminal 2 a character message including erroneous text, which is halting or slightly incorrect language, unlike normal text used by adults, the user U experiences an impulse to correct the error. As a result, the user U is motivated to input a user message to correct the error. By inputting a user message to correct the erroneous text in this way, communication is promoted and cognitive functions such as memory, comprehension, and problem-solving ability are stimulated, which is expected to prevent the user U from suffering from dementia or cognition (hereinafter referred to as "dementia, etc.") and to improve the condition of the user U's dementia, etc.

[0034] [Configuration of information processing device 1] 4 is a diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 has an image generation unit 131, a message transmission unit 132, and a message reception unit 133.

[0035] The communication unit 11 includes a communication interface for transmitting and receiving messages to and from the communication terminal 2 via the network N. The communication unit 11 transmits a character message input from the message sending unit 132, and inputs a user message received from the communication terminal 2 to the message receiving unit 133.

[0036] The storage unit 12 has storage media such as a read-only memory (ROM), a random access memory (RAM), and a solid-state drive (SSD). The storage unit 12 stores programs executed by the control unit 13. The storage unit 12 also stores data used by the message sending unit 132 to create character messages. The storage unit 12 stores, for example, one or more erroneous texts each having an error in part, in association with each of a plurality of regular texts.

[0037] 5 is a diagram showing an example of the erroneous text database stored in the storage unit 12. In the erroneous text database, a text ID, a regular text, an erroneous text, and a genre to which the noun represented by the regular text belongs are associated with each other. As shown in the example of FIG. 5, the erroneous text is, for example, text in which two adjacent characters among a plurality of characters included in the regular text are swapped (e.g., "ice cream" or "eberator"), or text in which one or more characters among a plurality of characters included in the regular text are swapped with characters that have the same vowel as the original character but different consonants (e.g., "otachi" or "panpanpan").

[0038] In the incorrect text database, the text ID may be associated with a corresponding normal text or a situation in which the incorrect text can be used. The storage unit 12 may also store multiple incorrect texts in association with one normal text.

[0039] FIG. 6 is a diagram showing an example of scenario data stored in the storage unit 12. In the scenario data, a progress stage ID, a situation name, and a genre of usable text are associated with each other. The scenario data is referenced when the message sending unit 132 generates a character message. In the scenario data, a progress stage ID, correct text, and incorrect text may be associated with each other. The scenario data may include information that can identify the progress stage ID that sent a character message in the past. The scenario data may include information indicating the time (e.g., the date) when a character message related to each progress stage was sent in the past.

[0040] The storage unit 12 may further store data of an image (e.g., a facial image) of a character to be transmitted to the communication terminal 2 together with a character message. The storage unit 12 stores, for example, a plurality of initial character images created in advance. The storage unit 12 may store, in association with the user U, a character image to be used when the message sending unit 132 transmits a character message to the user U. The storage unit 12 may store, in association with the initial character image, one or more changed character images obtained by partially changing the initial character image. The storage unit 12 may store a plurality of changed character images in association with information indicating the order in which the character images are changed.

[0041] The following describes the operation of each part of the control unit 13. The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes a program stored in the storage unit 12, thereby functioning as an image generation unit 131, a message transmission unit 132, and a message reception unit 133.

[0042] The image generation unit 131 generates a character image. For example, the image generation unit 131 reads out an initial character image stored in the storage unit 12, thereby generating a character image to be transmitted by the message sending unit 132 to the communication terminal 2. After the image generation unit 131 generates a first character image to be transmitted by the message sending unit 132 to the communication terminal 2 at a first time point, the image generation unit 131 may generate a second character image, which is obtained by changing a part of the first character image, to be transmitted by the message sending unit 132 to the communication terminal 2 at a second time point after the first time point. For example, the image generation unit 131 generates the second character image by selecting a changed character image to be used next from a plurality of changed character images stored in the storage unit 12, based on information indicating the order in which the character images stored in the storage unit 12 are to be changed.

[0043] As an example, the image generation unit 131 does not generate the second character image if the message receiving unit 133 does not receive a user message including correct text corresponding to the incorrect text after the message sending unit 132 sends a character message including incorrect text together with the first character image. The image generation unit 131 generates the second character image on the condition that the message receiving unit 133 receives a user message including correct text corresponding to the incorrect text after sending a character message including incorrect text together with the first character image.

[0044] The image generation unit 131 may determine how to change the first character image to generate the second character image according to the content of the user message. For example, the longer the user message correcting the erroneous text, the greater the change amount from the first character image that the image generation unit 131 generates the second character image.

[0045] When the user message does not contain regular text with the erroneous text corrected, the image generation unit 131 may generate a second character image by modifying the first character image to be contrary to the preferences of the user U stored in the memory unit 12, and when the user message contains regular text with the erroneous text corrected, the image generation unit 131 may generate a second character image by modifying the first character image to be consistent with the preferences of the user U stored in the memory unit 12.

[0046] If user U likes cute characters, when the user message contains correct text in which the erroneous text has been corrected, image generation unit 131 generates a second character image that contains more features that make the character appear cuter than the first character image. By image generation unit 131 generating the second character image in accordance with the content of the user message in this way, user U is motivated to input a user message that corrects the erroneous text.

[0047] The message sending unit 132 sends either a character message including erroneous text or a character message not including erroneous text to the communication terminal 2 via the communication unit 11. The message sending unit 132 selects a character message to send from a large number of character message templates stored in the storage unit 12. The message sending unit 132 sends a character message including erroneous text associated in the storage unit 12 with regular text selected from a plurality of regular texts stored in the storage unit 12. As an example, if the erroneous text database contains erroneous text corresponding to the regular text included in the selected character message, the message sending unit 132 sends a character message in which the regular text in the selected character message has been replaced with the erroneous text.

[0048] The message sending unit 132 transitions through the stages of progress indicated by the scenario data stored in the storage unit 12 over time, and sends character messages corresponding to the situations associated with the current stage of progress in the scenario data. When the message sending unit 132 refers to the scenario data shown in FIG. 6, the message sending unit 132 first sends a character message on a topic related to the zoo, which is the situation with a stage of progress ID of S001. For example, the message sending unit 132 first sends a character message saying, "Grandpa, we came to the zoo today," and starts exchanging messages with the user U.

[0049] The message sending unit 132 shifts the progress stage in the scenario data every time a predetermined period (for example, one day or one week) has passed. For example, after a predetermined period has passed since sending a character message about a topic related to a zoo, the message sending unit 132 sends a character message about a topic related to an amusement park, which is a situation with a progress stage ID of S002.

[0050] The message sending unit 132 sends a character message including erroneous text of a usable genre associated with each stage ID at each stage. For example, the message sending unit 132 sends a first character message including first erroneous text associated with a first stage indicated by the scenario data stored in the storage unit 12, and then sends a second character message including second erroneous text associated with a second stage that is the stage following the first stage.

[0051] As an example, the message sending unit 132 sends a food-related character message saying "I want to eat ice cream" when the progress stage ID is S001. The message sending unit 132 sends a hero-related character message saying "There are lots of people at this amusement park" when the progress stage ID is S002. In this way, the message sending unit 132 shifts the progress stage in the scenario data over time and changes the error text included in the character message for each progress stage, allowing the user U to enjoy sending and receiving messages without getting bored.

[0052] The message sending unit 132 sends a character message including erroneous text, and then the message receiving unit 133 receives a user message including normal text corresponding to the erroneous text, and then sends a character message including normal text corresponding to the sent erroneous text. For example, if the message sending unit 132 receives a character message saying "I'll put some ketchup on you," and then the message receiving unit 133 receives a user message saying "Ketchup, okay?", the message sending unit 132 sends a character message saying "Yes, I'll put some ketchup on you." By the message sending unit 132 operating in this manner, the user U recognizes that the effect of inputting a user message to correct the erroneous text has been achieved, which increases the user U's satisfaction and motivates him or her to input a user message to correct the erroneous text when he or she notices it.

[0053] However, if a user message containing normal text is received only once and character messages containing no erroneous text are subsequently sent, the user U may lose interest and become less motivated to enter user messages. Therefore, after receiving a user message containing normal text, the message sending unit 132 may send a character message containing erroneous text (e.g., "kechachu") that corresponds to the normal text and that differs from the erroneous text (e.g., "kepatchu") previously sent. By the message sending unit 132 sequentially sending character messages corresponding to a plurality of erroneous texts with different error patterns in this way, the user U's enjoyment increases, and the user U is motivated to enter user messages.

[0054] If the message sending unit 132 has sent a character message including erroneous text but the message receiving unit 133 has not received a user message including correct text corresponding to the erroneous text within a predetermined time, the message sending unit 132 may resend the character message including the erroneous text. The predetermined time is a time, for example, one day, determined based on statistics of the time required for the user U to send a user message after the message sending unit 132 has sent the character message. By resending the character message including erroneous text in this way, it is possible to give the user U an opportunity to notice the erroneous text if the user U has not noticed the erroneous text.

[0055] When retransmitting a character message including erroneous text, the message sending unit 132 may make the erroneous text bold or enclose it in parentheses so that the user U can easily notice the erroneous text. By operating the message sending unit 132 in this manner, the user U can easily notice the erroneous text, thereby increasing the probability that the user U will send a user message to correct the erroneous text.

[0056] After the message sending unit 132 sends a character message including erroneous text, if the message receiving unit 133 receives a user message including correct text corresponding to the erroneous text, the message sending unit 132 may send a character message including text expressing gratitude to the user U. The message sending unit 132 sends a character message including text expressing gratitude along with the erroneous text and the correct text, such as, for example, "Oh, it's ketchup, not kepatchu. Thank you for letting me know." When the user U receives such a character message, the user U's sense of satisfaction increases, and the user U is motivated to input a user message to correct the erroneous text when he or she notices it.

[0057] However, if character messages containing erroneous text are frequently sent, the user U may find it troublesome to correct the erroneous text and may avoid entering user messages. Therefore, the message sending unit 132 may not send a character message containing second erroneous text different from the first erroneous text until a predetermined first period has elapsed since the message receiving unit 133 received a user message containing correct text corresponding to the first erroneous text, and may send a character message containing the second erroneous text after the predetermined first period has elapsed. The predetermined first period may be, for example, one day. The predetermined period may be set by the user U, and the set predetermined first period may be stored in the storage unit 12 in association with the user U.

[0058] When the genre of the erroneous text sent to the user U is different, it is expected that the user U will be less bothered to correct the erroneous text than when erroneous text of the same genre is sent. Therefore, the message sending unit 132 may send a character message including second erroneous text associated with a genre different from the genre associated with the first erroneous text after a predetermined second period has elapsed since sending the character message including the first erroneous text.

[0059] The message sending unit 132 may send a character message including erroneous text when the user U has not sent a user message for a predetermined period of time (for example, one week or more). This may motivate the user U to send a user message by creating an urge to correct the user U who sees the character message including erroneous text.

[0060] The message sending unit 132 may send a character message that includes the erroneous text and a question for the user U. When teaching something to others, people think about how to organize information and explain it concisely. As a result, a protégé effect occurs in which the person teaching the other person deepens their own understanding. By the message sending unit 132 sending a character message that includes a question for the user U, the user U is motivated to send a user message to answer the question. As a result, the cognitive ability of the user U is activated, and it may be possible to prevent the user U from suffering from dementia, etc.

[0061] The message receiving unit 133 receives, via the communication unit 11, a user message input by the user U and transmitted by the communication terminal 2. After the message transmitting unit 132 transmits a character message including erroneous text to the communication terminal 2, the message receiving unit 133 receives from the communication terminal 2 a user message including correct text corresponding to the transmitted erroneous text. The message receiving unit 133 associates the received user message with the date and time of reception and stores it in the storage unit 12. The message receiving unit 133 may notify the message transmitting unit 132 of the received user message.

[0062] [Character image changes] To further motivate the user U to input a user message for correcting the erroneous text, the message sending unit 132 may change the character image to be sent next together with the user message when the message receiving unit 133 receives a user message for correcting the erroneous text. That is, the message sending unit 132 may send a character message including the erroneous text together with a first character image, and after the message receiving unit 133 receives a user message including correct text corresponding to the erroneous text, send a character message including a second character image obtained by changing a part of the first character image.

[0063] The message sending unit 132 may send a second character image that is a change from the first character image depending on the content of the user message. For example, the longer the user message correcting the erroneous text, the more the message sending unit 132 sends a second character image that is a larger change from the first character image.

[0064] The message sending unit 132 may send a second character image that has been changed from the first character image to be contrary to the preferences of the user U stored in the memory unit 12 when the user message does not contain regular text with the erroneous text corrected, and may send a second character image that has been changed from the first character image to be consistent with the preferences of the user U stored in the memory unit 12 when the user message contains regular text with the erroneous text corrected.

[0065] If user U likes cute characters, when the user message contains regular text in which the erroneous text has been corrected, message sending unit 132 sends a second character image that contains more characteristics that make the character appear cuter than the first character image. By sending the second character image, which is a change from the first character image in accordance with the content of the user message, message sending unit 132 motivates user U to input a user message that corrects the erroneous text.

[0066] [Processing flow in information processing device 1] 7 is a flowchart showing the flow of processing in the information processing device 1. The flowchart shown in FIG.

[0067] The message sending unit 132 selects a stage of progress corresponding to a situation in which a character message is to be sent (S11). The message sending unit 132 selects a stage of progress by, for example, referring to information stored in the storage unit 12 indicating stages of progress at which character messages have been sent in the past, or information indicating the time when character messages related to each stage of progress were sent in the past. The message sending unit 132 selects, for example, a stage of progress at which no character message has been sent in the past, or a stage of progress at which the longest time has passed since a character message was sent in the past.

[0068] Next, the message sending unit 132 identifies the available genre associated with the selected stage in the scenario data, and selects the error text corresponding to the available genre by referring to the error text database as shown in Figure 5 (S12). If there are multiple selectable error texts, the message sending unit 132 selects text that has not been sent before, or the error text that has been sent the longest time ago. The message sending unit 132 sends a character message including the selected error text (S13).

[0069] When the message receiving unit 133 receives a user message (YES in S14), the message sending unit 132 determines whether the received user message contains correct text corresponding to the erroneous text included in the sent character message (S15). If the user message contains correct text corresponding to the erroneous text (YES in S15), that is, if the user U has sent a user message to correct the erroneous text, the message sending unit 132 sends a character message containing erroneous text that differs from the erroneous text included in the character message sent in S13 (S16). Note that the message sending unit 132 may send a character message expressing gratitude to the user U, a character message that does not contain erroneous text, or the like, between S15 and S16.

[0070] If the user message does not include correct text corresponding to the erroneous text (NO in S15), that is, if the user U has not sent a user message to correct the erroneous text, the user U may not have noticed the erroneous text. Therefore, the message sending unit 132 sends a character message including the same erroneous text as the erroneous text included in the character message sent in S13 (S17). At this time, the message sending unit 132 may send the character message in a manner that makes the erroneous text more noticeable than the character message sent in S13.

[0071] Next, the message sending unit 132 determines whether it is time to change the stage of the scenario (S18). If it is not time to change the stage of the scenario (for example, midnight) and there is no need to change the stage of the scenario (NO in S18), the message sending unit 132 repeats the processes from S14 to S17. If it is time to change the stage of the scenario (YES in S18) and the user U has not performed an operation to end the message transmission and reception (NO in S19), the message sending unit 132 returns to S11 and selects the next stage of the scenario (S11). If the user U has performed an operation to end the message transmission and reception (YES in S19), the information processing device 1 ends the message transmission and reception.

[0072] [First Modification] In the above description, a case has been exemplified in which the message transmitted and received between the information processing device 1 and the communication terminal 2 is a message displayed as text, but the message may also be an audio message. In this case, as shown in Fig. 3, the message may be displayed on the communication terminal 2 and audio reading the message may be output from the speaker of the communication terminal 2. Audio reading the message may also be output from the speaker of the communication terminal 2 without the message being displayed on the communication terminal 2. In other words, the message sending unit 132 sends audio data of a character message including erroneous text.

[0073] When the message is output as audio, the erroneous text may be text corresponding to a pronunciation that is difficult to hear, rather than text corresponding to a correct pronunciation that is pre-stored in the storage unit 12. As an example, the audio data may be audio data in which clear sounds included in the correct text have been replaced with voiced sounds, audio data that is pronounced faster than the audio data corresponding to the correct text, or audio data that is pronounced quieter than the audio data corresponding to the correct text. In this way, the same effect can be achieved by the message sending unit 132 sending audio data that is difficult to hear, different from the correct audio data.

[0074] [Second Modification] In the above description, the message sending unit 132 identifies the incorrect text corresponding to the normal text by referring to the data stored in the storage unit 12. However, the message sending unit 132 may also identify the incorrect text using a machine learning model (e.g., a generative AI). The machine learning model is a first machine learning model that outputs incorrect text when normal text is input. The message sending unit 132 receives normal text to be included in the character message and transmits a character message including the incorrect text output from the first machine learning model.

[0075] The message sending unit 132 may use a second machine learning model that outputs a character message by inputting a user message received by the message receiving unit 133. The message sending unit 132 acquires a character message including normal text by inputting the user message received by the message receiving unit 133 into the second machine learning model. The message sending unit 132 transmits a character message including erroneous text by inputting the acquired character message into a first machine learning model. The first machine learning model may have the function of the second machine learning model, and the message sending unit 132 may transmit a character message including erroneous text by inputting the user message received by the message receiving unit 133 into the first machine learning model.

[0076] [Effects of information processing device 1] As described above, the information processing device 1 includes the message sending unit 132 that sends a character message including erroneous text to the communication terminal 2, and the message receiving unit 133 that receives a user message from the communication terminal 2. After the message receiving unit 133 receives a user message including correct text corresponding to the erroneous text, the message sending unit 132 sends a character message including correct text corresponding to the sent erroneous text, or sends a character message including erroneous text different from the sent erroneous text. With the information processing device 1 configured in this way, the user U is motivated to send a message to correct the erroneous text. As a result, it is possible to prevent the user U from suffering from dementia or improve the condition of dementia or the like.

[0077] The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination also have the effects of the original embodiments. [Explanation of symbols]
