PLD includes FPGA (Field-Programmable Gate Array). The control unit 22 may be one of SoC (System on a Chip) and SiP (System in a Package) in which one or a plurality of processors cooperate.

  For example, when acquiring a command to shift to the communication mode from the charging stand 12 as will be described later, the control unit 22 controls each component of the portable terminal 11 in order to execute various functions in the communication mode. Here, the communication mode refers to the communication system 10 together with the portable terminal 11 together with the charging stand 12, such as dialogue with a user to be dialogued including a specific user, observation of the specific user, and message transmission to the specific user. This is the mode to be executed.

  The control unit 22 executes a registration process for registering a user who executes the communication mode. The control unit 22 starts the registration process, for example, by detecting an input requesting user registration to the input unit 20.

  For example, in the registration process, the control unit 22 issues a message to the user to see the lens of the camera 18 and drives the camera 18 to capture the user's face. Further, the control unit 22 stores the captured image in association with user information such as a user name and attributes. The attributes are, for example, the owner of the mobile terminal 11 and the relationship or friendship with the owner, sex, age group, height, weight, and the like. The relationship indicates a family relationship with the owner of the mobile terminal 11 such as a parent and child or a brother. The friendship relationship indicates the degree of interaction with the owner of the mobile terminal 11 such as an acquaintance, best friend, classmate, or work colleague. The control unit 22 acquires user information by input by the user to the input unit 20.

  In the registration process, the control unit 22 further transfers to the charging stand 12 together with user information associated with the registered image. In order to give to the charging stand 12, the control unit 22 determines whether communication with the mobile terminal 11 is possible.

  When the control unit 22 cannot communicate with the charging stand 12, the control unit 22 displays a message for enabling communication on the display 19. For example, in a configuration in which the mobile terminal 11 performs wired communication with the charging stand 12, when the mobile terminal 11 and the charging stand 12 are not connected, the control unit 22 displays a message requesting connection on the display 19. Further, in the configuration in which the mobile terminal 11 performs wireless communication with the charging base 12, when the mobile terminal 11 and the charging base 12 are separated so as not to communicate, the control unit 22 displays a message requesting that the charging base 12 be approached. 19 is displayed.

  When the mobile terminal 11 and the charging stand 12 are communicable, the control unit 22 causes the registered image and user information to be transferred toward the charging stand 12 and displays on the display 19 that transfer is in progress. Further, when acquiring the transfer completion notification from the charging stand 12, the control unit 22 causes the display 19 to display an initial setting completion message.

  During the transition to the communication mode, the control unit 22 causes the communication system 10 to interact with the user to be interacted with by executing at least one of speech processing and speech recognition processing. The dialogue target user is a user registered in the registration process, for example, the owner of the portable terminal 11. Moreover, the control part 22 carries out the audio | voice output with the speaker 17 of the various information with respect to the user of dialog object as speech processing. The various information includes, for example, schedule contents, memo contents, mail sender, mail subject, telephone caller, and the like.

  The utterance content in the utterance process executed by the control unit 22 is changed according to the private level. The private level is a degree indicating the degree to which private information of the user to be interacted (information related to the individual who identifies the user to be interacted) can be included in the utterance content. The private level is set according to people around the mobile terminal 11. The private level may vary depending on the relationship or friendship between the person around the mobile terminal 11 and the user to be interacted with. The private level includes a first level including, for example, a person (for example, another person) who is not familiar with the user to be interacted with around the mobile terminal 11. The private level includes, for example, a second level in which people around the mobile terminal 11 are a user who is a conversation target and a person who is close to the user who is a conversation target (for example, a family or a best friend). In addition, the private level includes, for example, a third level in which a person around the mobile terminal 11 is only a user to be interacted with.

  The utterance contents when the private level is the first level (hereinafter referred to as “first level utterance contents”) are, for example, contents that do not include any private information, or disclosure is permitted for unspecified users. Contents. For example, the utterance content of the first level in the case of outputting a voice about a schedule is “There is a schedule today”. Further, for example, the content of the first level utterance in the case of outputting a voice about a memo is “I have a memo”. Also, for example, the first level utterance content when a voice is output for a mail is “mail is coming”. Also, for example, the first level utterance content when a voice is output for a telephone is “There was an incoming call”.

  The utterance content when the private level is the second level or the third level (hereinafter referred to as “second or third level utterance content”) is, for example, content including private information or a user to be interacted with This is the content permitted to be disclosed. For example, the content of the utterance at the second or third level in the case of outputting a voice about the schedule is “There is a schedule for a welcome and farewell party at 19:00 today”. Further, for example, the content of the utterance at the second or third level in the case of outputting a voice about a memo is “It is necessary to submit a report Y tomorrow”. Further, for example, the content of the utterance at the second or third level in the case of outputting a voice about a mail is “A mail comes from Mr. A to Z”. Further, for example, the content of the utterance at the second or third level when the voice is output for the telephone is “Mr. A received an incoming call”.

  Here, the user can set the content permitted to be disclosed from the first level to the third level by the input unit 20. For example, the user can individually set, for example, whether or not to notify by voice that there is a schedule set in the schedule, that there is a memo, that an email is received, that there is a call, and the like. Further, the user can individually set, for example, whether or not to output the contents of the schedule, the contents of the memo, the mail sender, the mail subject, the telephone caller, and the like. Also, the user can individually set whether or not to execute a change in accordance with the private level, for example, the contents of the schedule, the contents of the memo, the sender of the mail, the subject of the mail, the caller of the telephone. In addition, the user can set a person who discloses information at the second level, for example, based on a relationship or friendship. These set contents (hereinafter referred to as “setting information”) are stored, for example, in the storage unit 21, and are synchronized and shared with the charging stand 12.

  In the utterance process, the control unit 22 determines the current time, the place where the charging stand 12 is installed, the user to be interacted with specified as the charging stand 12 as described later, the mail and phone received by the mobile terminal 11, the mobile terminal 11 The words to be uttered are determined based on the memo and schedule registered in, the voice uttered by the user, and the past conversation contents of the user.

The control part 22 performs the content change process which changes the content output by the speaker 17 according to a private level, when the word to speak is based on predetermined information. In the present embodiment, the predetermined information is a schedule, a memo, an email, and a telephone. The control unit 22 determines whether or not the content to be output is a content change process target in accordance with the setting information. The control unit 22 executes content change processing for the target content.

  The control unit 22 determines whether it is placed on the charging stand 12 or detached from the charging stand 12 in order to determine the utterance content. Based on the placement notification acquired from the charging stand 12, the control unit 22 determines whether it is placed or detached. For example, the control unit 22 determines that the information is placed on the charging stand 12 while acquiring the notification indicating that it is placed from the charging stand 12. Further, for example, the control unit 22 determines that it has been detached when the notification cannot be acquired. Alternatively, the control unit 22 controls the charging base 12 of the mobile terminal 11 based on whether the power receiving unit 14 can acquire power from the charging base 12 or whether the communication unit 13 can communicate with the charging base 12. The placement relationship may be determined.

  Further, in the voice recognition process, the control unit 22 performs a morphological analysis of the voice detected by the microphone 16 and recognizes the content of the user's utterance. The control unit 22 executes predetermined processing based on the recognized utterance content. The predetermined process is, for example, a process for executing an utterance process for the utterance content recognized as described above, a search for desired information, a display of a desired image, and a call and mail transmission to a desired partner. is there.

  Further, the control unit 22 stores the above-described utterance processing and voice recognition processing, which are continuously executed during the transition to the communication mode, in the storage unit 21, and learns the conversation contents for the specified user to be interacted with. To do. Based on the learned conversation content, the control unit 22 is used to determine words to be uttered in the subsequent utterance processing. Further, the control unit 22 may transfer the learned conversation content to the charging stand 12.

  Further, the control unit 22 detects the current position of the mobile terminal 11 while shifting to the communication mode. The detection of the current position is based on, for example, the installation position of the base station in communication or the GPS that the mobile terminal 11 may have. The control unit 22 notifies the user of the area information associated with the detected current position. The notification of the area information may be a voice utterance by the speaker 17 or an image display on the display 19. The regional information is, for example, sales information on nearby stores.

  In addition, when the input unit 20 detects a start request for watching processing for a specific target while shifting to the communication mode, the control unit 22 notifies the charging base 12 of the start request. The specific target is, for example, a registered specific user and a room where the charging stand 12 is installed.

  The watching process is executed by the charging stand 12 regardless of whether the portable terminal 11 is placed. When acquiring a notification that the specific target is in an abnormal state from the charging stand 12 that is executing the watching process, the control unit 22 notifies the user of that fact. The notification to the user may be a voice transmission by the speaker 17 or a warning image displayed on the display 19.

Therefore, when the mobile terminal 11 is placed on the charging stand 12, the control unit 32 can cause the mobile terminal 11 to execute at least one of the speech process and the voice recognition process. In addition, the control unit 32 can cause the mobile terminal 11 to execute at least one of the speech process and the voice recognition process until a predetermined time after the mobile terminal 11 is detached from the charging stand 12.

  While the mobile terminal 11 is placed on the charging stand 12, the control unit 32 determines the presence or absence of a person around the charging stand 12 based on the detection result of the human sensor 29. When determining that there is a person, the control unit 32 activates at least one of the microphone 26 and the camera 28 to detect at least one of sound and image, respectively. The control unit 32 specifies a user to be interacted with based on at least one of the detected voice and image. And the control part 32 determines the relationship with the user of a dialog target about the person around the charging stand 12, and determines a private level. In the present embodiment, the control unit 32 determines the private level based on the image.

  For example, the control unit 32 determines the number of persons around the charging stand 12 (or around the portable terminal 11 when placed) from the acquired image. Moreover, the control part 32 specifies the user of the dialogue target around the charging stand 12 from features, such as a person's face contained in an image, a back appearance, and a whole outline. Further, the control unit 32 specifies a person other than the user to be interacted with around the charging stand 12. Here, the control part 32 may acquire an audio | voice further. The control unit 32 may verify (or specify) the number of people around the charging stand 12 based on the loudness, height, and voice quality of the acquired voice. Further, the control unit 32 may verify (or specify) the user to be interacted with based on these features of the voice. Further, the control unit 32 may verify (or specify) a person other than the user to be interacted with based on these features of the voice.

When the control unit 32 specifies the user to be interacted with, the control unit 32 identifies the relationship between other users around the charging stand 12 and the user to be interacted with. The control unit 32 determines the private level as the third level when there is no other person around the charging stand 12, that is, when there is only a user who is an object of interaction around the charging stand 12. The control unit 32 notifies the mobile terminal 11 that the private level is the third level along with the information on the identified user to be interacted with. The control unit 32 determines the private level as the second level when there are only a user who is a conversation target and a person close to the user who is a conversation target (for example, family, best friend, etc.) around the charging stand 12. Here, the control unit 32 determines whether or not a person other than the conversation target user is a close person based on the user information transferred from the portable terminal 11 to the charging stand 12. The control unit 32 notifies the mobile terminal 11 that the private level is the second level, along with information about the identified user to be interacted with and other people around the charging stand 12. The control unit 32 determines the private level as the first level when there is a person (for example, another person) who is not familiar with the user to be interacted around the charging stand 12. The control unit 32 notifies the mobile terminal 11 that the private level is the first level along with the information on the identified user to be interacted with. When the person around the charging stand 12 includes a person who cannot be determined based on the user information, the control unit 32 determines the private level as the first level and notifies the portable terminal 11 of it. Here, when the control unit 32 determines that the content change process is not executed (invalid) for all information (for example, schedule, memo, mail, and telephone) based on the setting information, The determination and notification to the mobile terminal 11 may not be executed.

  While the mobile terminal 11 is placed on the charging stand 12, the control unit 32 continues imaging with the camera 28 and searches for the face of the user as a specific dialogue target for each image.

  When the placement sensor 30 detects the placement of the mobile terminal 11, the control unit 32 starts the transition of the communication system 10 to the communication mode. Therefore, when the portable terminal 11 is placed on the charging stand 12, the control unit 32 causes the portable terminal 11 to start executing at least one of the speech process and the voice recognition process. In addition, when the placement sensor 30 detects the placement of the mobile terminal 11, the control unit 32 notifies the mobile terminal 11 that it is placed.

  In addition, the control unit 32 ends the communication mode in the communication system 10 when the placement sensor 30 detects the detachment of the mobile terminal 11 or after a predetermined time after the detection. Therefore, the control unit 32 causes the portable terminal 11 to finish executing at least one of the speech process and the voice recognition process when the portable terminal 11 is detached from the charging stand 12 or after a predetermined time has elapsed after detection.

  Further, when acquiring the conversation content for each user from the mobile terminal 11, the control unit 32 stores the conversation content in the storage unit 31 for each mobile terminal 11. The control part 32 is made to share the conversation content memorize | stored between the different portable terminals 11 which communicate directly or indirectly with the charging stand 12 as needed. Here, indirect communication with the charging stand 12 means that the charging stand 12 is connected to a telephone line, communicates via the telephone line, and via the mobile terminal 11 placed on the charging stand 12. And at least one of communicating.

  Moreover, the control part 32 performs a monitoring process, when acquiring the command which performs a monitoring process from the portable terminal 11. FIG. In the watching process, the control unit 32 activates the camera 28 and performs continuous imaging of a specific target. The control unit 32 extracts a specific target from the image captured by the camera 28. The control unit 32 determines the state of the extracted specific target based on image recognition or the like. The state of the specific target is, for example, an abnormal state in which the specific user has fallen down, or a detection state of a moving object in the absence room. When determining that the specific target is in an abnormal state, the control unit 32 notifies the mobile terminal 11 that has instructed execution of the watching process that the specific target is in an abnormal state.

  Next, an initial setting process executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG. The initial setting process starts when the input unit 20 detects an input for starting the initial setting by the user.

  In step S <b> 100, the control unit 22 causes the display 19 to display a message requesting that the camera 18 of the mobile terminal 11 meet the face. After displaying on the display 19, the process proceeds to step S101.

  In step S101, the control unit 22 causes the camera 18 to perform imaging. After imaging, the process proceeds to step S102.

  In step S102, the control unit 22 causes the display 19 to display a question asking for the user name and attributes. After displaying the question, the process proceeds to step S103.

  In step S103, the control unit 22 determines whether or not there is an answer to the question in step S102. If there is no answer, the process repeats step S103. When there is an answer, the process proceeds to step S104.

  In step S104, the control unit 22 stores the face image captured in step S101 in the storage unit 21 in association with the answer to the question detected in step S103 as user information. After storing, the process proceeds to step S105.

  In step S <b> 105, the control unit 22 determines whether communication with the charging stand 12 is possible. When communication is impossible, the process proceeds to step S106. When communication is possible, the process proceeds to step S107.

  In step S <b> 106, the control unit 22 causes the display 19 to display a message requesting an action that enables the display 19 to communicate with the charging stand 12. In the configuration in which the mobile terminal 11 performs wired communication with the charging stand 12, the message requesting the action for enabling communication is, for example, “Place it on the charging stand”. In addition, the message requesting the action for enabling communication is, for example, “Please move closer to the charging stand 12” in the configuration in which the mobile terminal 11 performs wireless communication with the charging stand 12. After displaying the message, the process returns to step S105.

  In step S107, the control unit 22 transfers the face image and user information stored in step S104 to the charging stand 12. Further, the control unit 22 causes the display 19 to display a message indicating that the transfer is in progress. After starting the transfer, the process proceeds to step S108.

  In step S <b> 108, the control unit 22 determines whether a transfer completion notification has been acquired from the charging stand 12. If not, the process repeats step S108. If so, the process proceeds to step S109.

  In step S109, the control unit 22 causes the display 19 to display a message indicating completion of the initial setting. After the display, the initial setting process ends.

  Next, private setting processing executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG. The private setting process starts when the input unit 20 detects an input for starting the private setting by the user.

  In step S <b> 200, the control unit 22 causes the display 19 to display a message requesting the user to execute the private setting. After displaying on the display 19, the process proceeds to step S201.

  In step S201, the control unit 22 protects private information when, for example, notifying that there is a schedule set in the schedule, that there is a memo, that an e-mail has been received, or that there was a call, by voice. A question asking whether or not is displayed on the display 19. In addition, the control unit 22 displays a question asking whether or not to protect private information when, for example, the contents of a schedule, the contents of a memo, the sender of an email, the subject of an email, the caller of a phone call, etc. 19 is displayed. Moreover, the control part 22 displays the question which asks the range of the person who discloses information when a private level is a 2nd level on the display 19. FIG. After displaying the question, the process proceeds to step S202.

  In step S202, the control unit 22 determines whether or not there is an answer to the question in step S201. If there is no answer, the process repeats step S202. When there is an answer, the process proceeds to step S203.

  In step S <b> 203, the control unit 22 associates the answer to the question detected in step S <b> 202 as setting information, and stores it in the storage unit 21. After storage, the process proceeds to step S204.

  In step S204, the control unit 22 determines whether or not communication with the charging stand 12 is possible. When communication is impossible, the process proceeds to step S205. When communication is possible, the process proceeds to step S206.

  In step S <b> 205, the control unit 22 causes the display 19 to display a message requesting an action that allows the display 19 to communicate with the charging stand 12. In the configuration in which the mobile terminal 11 performs wired communication with the charging stand 12, the message requesting the action for enabling communication is, for example, “Place it on the charging stand”. In addition, the message requesting the action for enabling communication is, for example, “Please move closer to the charging stand 12” in the configuration in which the mobile terminal 11 performs wireless communication with the charging stand 12. After displaying the message, the process returns to step S204.

  In step S206, the control unit 22 transfers the setting information stored in step S203 to the charging stand 12. Further, the control unit 22 causes the display 19 to display a message indicating that the transfer is in progress. After starting the transfer, the process proceeds to step S207.

  In step S <b> 207, the control unit 22 determines whether or not a transfer completion notification has been acquired from the charging stand 12. If not, the process repeats step S207. If so, the process proceeds to step S208.

  In step S208, the control unit 22 causes the display 19 to display a message indicating the completion of private setting. After the display, the private setting process ends.

  Next, speech execution execution determination processing executed by the control unit 32 of the charging stand 12 in the present disclosure will be described with reference to the flowchart of FIG. The control unit 32 may periodically start execution determination processing such as speech.

  In step S <b> 300, the control unit 32 determines whether or not the placement sensor 30 detects the placement of the mobile terminal 11. If so, the process proceeds to step S301. When not detected, the execution determination process such as utterance ends.

  In step S <b> 301, the control unit 32 drives the fluctuation mechanism 25 and the human sensor 29 to detect whether or not there is a person around the charging stand 12. After driving the fluctuation mechanism 25 and the human sensor 29, the process proceeds to step S302.

  In step S <b> 302, the control unit 32 determines whether or not the human sensor 29 detects a person around the charging stand 12. When detecting surrounding people, the process proceeds to step S303. When the surrounding people are not detected, the execution determination process such as utterance ends.

  In step S303, the control unit 32 drives the camera 28 to detect an image. After obtaining the detected image, the process proceeds to step S304. Here, the detected image includes at least an image around the charging stand 12. Here, in step S303, the control unit 32 may drive the microphone 26 together with the camera 28 to detect sound.

  In step S304, the control unit 32 searches for a human face included in the image acquired by imaging in step S303. After the face search, the process proceeds to step S305.

  In step S <b> 305, the control unit 32 compares the face searched in step S <b> 304 with the registered face image stored in the storage unit 31, thereby specifying the user to be interacted with. The control unit 32 also specifies a person other than the conversation target user included in the image. That is, when there are a plurality of persons around the charging stand 12, the control unit 32 specifies each person. For example, the control unit 32 recognizes that there is another person around the charging stand 12 when an unidentified person (for example, a person who has not registered a face image) is included in the image. Moreover, the control part 32 specifies the position in the image of the face of the user of the dialogue target for the process of directing the direction of the face of the user of the dialogue target on the display 19 of the mobile terminal 11. After identification, the process proceeds to step S306.

  In step S306, the control unit 32 determines the private level based on the identification of the person included in the image in step S305. The control unit 32 specifies a relationship or friendship with the user who is the dialog target for a person other than the specified user who is the dialog target. After determining the private level, the process proceeds to step S307.

  In step S307, the control unit 32 notifies the portable terminal 11 of the private level determined in step S306. After notification, the process proceeds to step S308.

  In step S308, based on the face position detected in step S305, the control unit 32 changes the change mechanism 25 so that the display 19 of the mobile terminal 11 faces the face of the user to be interacted captured in step S303. Drive. After driving the fluctuation mechanism 25, the process proceeds to step S309.

  In step S309, the control unit 32 notifies the portable terminal 11 of an instruction to start at least one of the speech process and the voice recognition process. After notification, the process proceeds to step S310.

  In step S <b> 310, the control unit 32 determines whether or not the placement sensor 30 has detected the detachment of the mobile terminal 11. If not, the process returns to step S303. If so, the process proceeds to step S311.

  In step S311, the control unit 32 determines whether or not a predetermined time has elapsed since the detection of separation. If the predetermined time has not elapsed, the process returns to step S311. If the predetermined time has elapsed, the process proceeds to step S312.

  In step S312, the control unit 32 notifies the portable terminal 11 of an instruction to end at least one of the speech process and the voice recognition process.

  Next, private level recognition processing executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG. The private level recognition process starts when the private level notified by the charging stand 12 is acquired.

  In step S400, the control unit 22 recognizes the acquired private level. Based on the recognized private level, the control unit 22 executes a content change process for changing the utterance contents in the subsequent utterance process. After the recognition of the private level, the private level recognition process ends.

  Next, the content change process which the control part 22 of the portable terminal 11 performs in this indication is demonstrated using the flowchart of FIG. The content change process starts when the mobile terminal 11 recognizes the private level notified by the charging stand 12, for example. The content change process may be executed periodically, for example, from when the mobile terminal 11 recognizes the private level until receiving a command to end the speech process.

  In step S500, the control unit 22 determines whether or not there is a schedule to be notified to the user to be interacted with. For example, if there is a schedule that has not yet been notified to the user to be interacted and is within a predetermined time until the scheduled execution date and time, the control unit 22 determines that there is a schedule to be notified. If there is a schedule to be notified, the process proceeds to step S600. If there is no schedule to be notified, the process proceeds to step S501.

  In step S600, the control unit 22 executes a schedule notification subroutine to be described later. After execution of the schedule notification subroutine, the process proceeds to step S501.

  In step S501, the control unit 22 determines whether there is a memo to be notified to the user to be interacted with. For example, if there is a newly registered memo that has not yet been notified to the user to be interacted with, the control unit 22 determines that there is a memo to be notified. If there are notes to be notified, the process proceeds to step S700. If there is no memo to be notified, the process proceeds to step S502.

  In step S700, the control unit 22 executes a memo notification subroutine to be described later. After execution of the memo notification subroutine, the process proceeds to step S502.

  In step S502, the control unit 22 determines whether there is an email to be notified to the user to be interacted with. For example, if there is a newly received mail that has not yet been notified to the user to be interacted with, the control unit 22 determines that there is a mail to be notified. If there is an email to be notified, the process proceeds to step S800. If there is no mail to be notified, the process proceeds to step S503.

  In step S800, the control unit 22 executes a mail notification subroutine to be described later. After execution of the mail notification subroutine, the process proceeds to step S503.

  In step S503, the control unit 22 determines whether there is a telephone call to be notified to the user to be interacted with. For example, if there is an incoming call addressed to the user to be interacted with, or if there is a recording memo of a telephone that has not been notified to the user to be interacted with, the control unit 22 determines that there is an incoming call to be notified. If there is an incoming call to be notified, the process proceeds to step S900. If there is no incoming call to be notified, the content change process ends.

  In step S900, the control unit 22 executes a telephone call notification subroutine described later. After executing the telephone call notification subroutine, the content change process ends. In addition, when there is at least one of a schedule, a memo, an email, and an incoming call to be notified in the content change process, the control unit 22 outputs the utterance content that has undergone the content change process in the utterance process.

  Next, a schedule notification subroutine S600 executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG.

  In step S601, the control unit 22 determines whether or not the private level is the first level. If it is not the first level (when it is the second level or the third level), the control unit 22 ends the schedule notification subroutine S600. If it is the first level, the process proceeds to step S602.

  In step S602, the control unit 22 determines whether the private setting is valid for notifying the schedule by voice based on the setting information. Here, that the private setting is valid means that the private information is protected. By referring to the setting information generated in the private setting process, the control unit 22 determines whether the private setting is valid for each of predetermined information (schedule, memo, mail, and telephone) that is the target of the content change process. It is possible to determine whether or not. If the private setting is valid for notifying the schedule by voice, the process proceeds to step S603. If the private setting is not valid, the process proceeds to step S604.

  In step S603, the control unit 22 changes the utterance content to none. That is, the control unit 22 changes the schedule so as not to speak.

  In step S604, the control unit 22 determines whether the private setting is valid for the contents of the schedule. If the private setting is valid, the process proceeds to step S605. If the private setting is not valid, the control unit 22 ends the schedule notification subroutine S600.

  In step S605, the control unit 22 changes the utterance content to a fixed phrase. For example, the fixed phrase is stored in the storage unit 21. For example, the control unit 22 changes the utterance content “There is a schedule for a welcome and farewell party at 19:00 today” to “There is a schedule today” which is a fixed phrase that does not include private information. After changing the utterance content, the control unit 22 ends the schedule notification subroutine S600.

  Next, a memo notification subroutine S700 executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG.

  In step S701, the control unit 22 determines whether or not the private level is the first level. If it is not the first level (if it is the second level or the third level), the control unit 22 ends the memo notification subroutine S700. If it is the first level, the process proceeds to step S702.

  In step S <b> 702, the control unit 22 determines whether the private setting is valid for notifying the memo by voice based on the setting information. If the private setting is valid, the process proceeds to step S703. If the private setting is not valid, the process proceeds to step S704.

  In step S703, the control unit 22 changes the utterance content to none. That is, the control unit 22 changes so as not to speak about the memo.

  In step S704, the control unit 22 determines whether the private setting is valid for the contents of the memo. If the private setting is valid, the process proceeds to step S705. If the private setting is not valid, the control unit 22 ends the memo notification subroutine S700.

  In step S705, the control unit 22 changes the utterance content to a fixed phrase. For example, the fixed phrase is stored in the storage unit 21. For example, the control unit 22 changes the utterance content “It is necessary to submit the report Y tomorrow” to “I have a memo” which is a fixed phrase that does not include private information. After changing the utterance content, the control unit 22 ends the memo notification subroutine S700.

  Next, a mail notification subroutine S800 executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG.

  In step S801, the control unit 22 determines whether or not the private level is the first level. When it is not the first level (when it is the second level or the third level), the control unit 22 ends the mail notification subroutine S800. If it is the first level, the process proceeds to step S802.

  In step S <b> 802, the control unit 22 determines whether the private setting is valid for notifying the mail by voice based on the setting information. If the private setting is valid, the process proceeds to step S803. If the private setting is not valid, the process proceeds to step S804.

  In step S803, the control unit 22 changes the utterance content to none. That is, the control unit 22 changes so as not to speak about the mail.

  In step S804, the control unit 22 determines whether the private setting is valid for at least one of the mail destination and the subject. If the private setting is valid, the process proceeds to step S805. If neither the mail destination nor the subject is private, the control unit 22 ends the mail notification subroutine S800.

  In step S805, the control unit 22 changes the mail address and subject whose private setting is valid to the fixed phrase or “none”. For example, the fixed phrase is stored in the storage unit 21. For example, when the private setting of the mail destination and subject is valid, the control unit 22 changes the utterance content “A mail is received from Mr. A to Z” to “A mail is received”. For example, if only the private setting of the email subject is valid, the control unit 22 changes the utterance content “A message from Mr. A to Z” to “A message from Mr. A”. To do. For example, when only the private setting of the mail destination is valid, the control unit 22 changes the utterance content “A message is received from Mr. A in the case of Z” to “A mail is received in the case of Z”. change. After changing the utterance content, the control unit 22 ends the mail notification subroutine S800.

  Next, an incoming call notification subroutine S900 executed by the control unit 22 of the mobile terminal 11 in the present disclosure will be described with reference to the flowchart of FIG.

  In step S901, the control unit 22 determines whether or not the private level is the first level. If it is not the first level (if it is the second level or the third level), the control unit 22 ends the subroutine S900 for the incoming call notification. If it is the first level, the process proceeds to step S902.

  In step S902, based on the setting information, the control unit 22 determines whether the private setting is valid for notifying the incoming call by voice. If the private setting is valid, the process proceeds to step S903. If the private setting is not valid, the process proceeds to step S904.

  In step S903, the control unit 22 changes the utterance content to none. That is, the control unit 22 changes so as not to speak about incoming calls.

  In step S904, the control unit 22 determines whether the private setting is valid for the caller of the incoming call. If the private setting is valid, the process proceeds to step S905. If the private setting is not valid, the control unit 22 ends the incoming call notification subroutine S900.

  In step S905, the control unit 22 changes the utterance content to a fixed phrase. For example, the fixed phrase is stored in the storage unit 21. For example, the control unit 22 changes the utterance content “There was an incoming call from Mr. A” to “There was an incoming call” which is a fixed phrase that does not include private information. For example, the control unit 22 changes the utterance content “There is a message memo of Mr. A” to “I have a message memo” which is a fixed phrase that does not include private information. After changing the content of the utterance, the control unit 22 ends the telephone call notification subroutine S900.

  The interactive electronic device according to the present embodiment having the above-described configuration executes a content change process for changing the content to be output by the speaker based on the private level of the user to be interacted with. The private level is set according to the people around the device. In an interactive electronic device, convenience is enhanced by performing various notifications by voice to a user who is to interact. On the other hand, when there is a person who is not close to the user to be interacted around the interactive electronic device, it is not preferable to output the sound including the private information. With the configuration as described above, the interactive electronic device according to the present embodiment can protect the personal information of the user to be interacted with by executing the content change process. Thus, the function of the interactive electronic device is improved as compared with the conventional interactive electronic device.

  The interactive electronic device according to the present embodiment is a mobile terminal 11. The control unit 22 executes the content changing process when the own device (mobile terminal 11) is placed on the charging stand 12. Generally, the user of the mobile terminal 11 who is out often starts charging the mobile terminal 11 immediately after returning home. Therefore, the interactive electronic device can notify the user of a notification addressed to the user at an appropriate timing such as when the user returns home. Thus, the function of the interactive electronic device is improved as compared with the conventional interactive electronic device.

  Moreover, the charging stand 12 which concerns on this embodiment makes the portable terminal 11 perform at least one of an utterance process and a speech recognition process, when the portable terminal 11 is mounted. With such a configuration, the charging stand 12 can be a conversation partner with the user together with the portable terminal 11 that executes a predetermined function alone. Therefore, for example, the charging stand 12 becomes a conversation partner during the meal of the elderly living alone, and can prevent the elderly from eating alone. Thus, the function of the charging stand 12 is improved compared to the conventional charging stand.

  Moreover, the charging stand 12 according to the present embodiment causes the mobile terminal 11 to start executing at least one of the speech process and the voice recognition process when the mobile terminal 11 is placed. Therefore, the charging stand 12 can start a dialogue with the user without requiring a complicated input by placing the portable terminal 11.

  Moreover, the charging stand 12 according to the present embodiment causes the mobile terminal 11 to finish at least one of the speech process and the voice recognition process when the mobile terminal 11 is detached. Therefore, the charging stand 12 can terminate the dialogue with the user and the like only by detaching the mobile terminal 11 without requiring a complicated input.

  In addition, the charging stand 12 according to the present embodiment drives the variation mechanism 25 so that the display 19 of the mobile terminal 11 faces the user who is the execution target of at least one of the speech process and the voice recognition process. Therefore, the charging stand 12 can make the said user recognize the communication system 10 like the person who actually talks at the time of a dialog with a user.

  In addition, the charging stand 12 according to the present embodiment can share the content of the conversation with the user between the different mobile terminals 11 that communicate with the charging stand 12. With such a configuration, the charging stand 12 can cause other users to understand the conversation contents of a specific user. Therefore, the charging stand 12 can share the conversation content with a family at a remote location, and can facilitate communication between the families.

  Moreover, the charging stand 12 which concerns on this embodiment judges the state of a specific object, and notifies it to the user of the portable terminal 11 when it is in an abnormal state. Therefore, the charging stand 12 can watch over a specific object.

  In addition, the communication system 10 according to the present embodiment determines words to be uttered based on past conversation contents, voices uttered, a place where the charging stand 12 is installed, and the like for a user who is a conversation target. With such a configuration, the communication system 10 can perform a conversation in accordance with the current conversation contents and past conversation contents of the user who is talking and the installation location.

  In addition, the communication system 10 according to the present embodiment can learn an action history of a specific user and output advice to the user. With such a configuration, the communication system 10 enables the notification when the medicine should be taken, the proposal of the user's favorite meal, the proposal of the meal contents for the user's health, and the user can continue and effectively By proposing exercise, it is possible to make the user recognize that it is easy to forget and that the user is unknown.

  In addition, the communication system 10 according to the present embodiment notifies information associated with the current position. With such a configuration, the communication system 10 can teach the user regional information specialized in the vicinity of the user's residence.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various variations and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention.

  For example, in the present embodiment, the control unit 22 of the mobile terminal 11 executes a content change process according to the private level, a speech process with a content according to the content change process, and a voice recognition process. The control unit 32 may execute. In the configuration executed by the control unit 32 of the charging stand 12, the microphone 26, the speaker 27, and the camera 28 of the charging stand 12 may be driven in the dialog with the user, or the microphone 16, the speaker 17 of the portable terminal 11, The camera 18 may be driven via the communication units 23 and 13.

  In the present embodiment, the control unit 22 of the mobile terminal 11 may cause at least a part of the process (for example, a private level determination process) executed by the control unit 32 of the charging stand 12 to be executed.

  In the present embodiment, the schedule notification subroutine, the memo notification subroutine, the mail notification subroutine, and the telephone call notification subroutine indicate that the private level is the first level (step S601). , Step S701, Step S801 and Step S901). However, these subroutines may be individually (independent of each other) that the private level is “first level or second level” and that the subroutine is not in a private state.

  In the present embodiment, when the private level is the second level or the third level, the utterance content is not changed because it is in the private state. Here, when the private level is the second level, the utterance content may be changed from the content of the third level (content that completely includes private information). For example, in the case of outputting a voice about a schedule, it is assumed that the content of the utterance at the third level is “There is a farewell party scheduled at place X at 19:00 today”. At this time, the control unit 22 may change the content of the utterance at the second level to “there is a farewell party”. That is, the control unit 22 may omit the content determined as important private information (in this example, time and place) and set it as the second level utterance content. At this time, the utterance content is adjusted so that private information is included in stages in accordance with the private level from the first level to the third level. Therefore, it is possible to protect private information more appropriately according to the private level.

  Moreover, in this embodiment, combining the said modification, the control part 32 of the charging stand 12 performs a content change process, a speech process, a speech recognition process, etc., and the control part 22 of the portable terminal 11 determines private level. Processing or the like may be executed.

  Moreover, in this embodiment, although the control part 22 of the portable terminal 11 performs a registration process, the control part 32 of the charging stand 12 may perform.

  In the present embodiment, the private setting process is executed by an input to the input unit 20 by the user. The private setting process generates setting information that individually sets whether or not the private setting is valid for each of predetermined information (schedule, memo, mail, and telephone) that is a target of the content change process. The setting information can be changed by executing the private setting process again. Here, the batch setting information change (private setting valid / invalid switching) may be executed by a specific conversation between the interactive electronic device and the user. For example, when the user utters a specific word (for example, a reply “Yes”) after talking about the weather, the setting information is updated by the control unit 22, and all of the schedule, memo, mail, and phone call are batched. Private settings may be enabled (or disabled). In addition, for example, when an image registered by the user on the touch panel (for example, a character's face) is displayed and the user touches a specific position of the registered image in a specific order (for example, the order of eyes, mouth, and nose) Private settings may be enabled (or disabled) for all schedules, memos, emails, and calls. In addition, for example, when there is no conversation between the interactive electronic device and the user for a certain period of time, the private setting may be enabled (or disabled) for all of the schedule, memo, mail, and telephone. Also, for example, when face recognition performed by an interactive electronic device makes it impossible for the user to confirm, private settings may be enabled (or disabled) for all schedules, memos, emails, and telephones. Further, for example, when the user presses down a specific button such as a power button, the private setting may be enabled (or disabled) for all of the schedule, memo, mail, and phone. With such a function, the private setting can be made as quickly as the user thinks. For example, when a conversation is made without initially setting a private setting and another person suddenly comes in, the private setting can be enabled without being noticed by the other person. Also, when another person leaves and becomes a private space, it is possible to output necessary information by voice by invalidating the private setting at once. Here, a confirmation screen may be displayed to the user before the private setting is collectively enabled (or disabled). Further, in the present embodiment, whether or not there is another person around is confirmed by the control unit 32 driving the camera 28 and searching for a human face from the image (steps S303 to S305 in FIG. 6). ) Was running. Here, the control unit 32 may confirm whether or not there is another person around by voice recognition (voiceprint recognition). In addition, the control unit 32 may check whether there is another person around by using a specific conversation between the interactive electronic device and the user as described above. In addition, the control unit 32 may check whether there is another person around by using the order of touching the registered images as described above.

  In the present embodiment, the content change process is executed when words spoken in the utterance process are based on a schedule, a memo, an email, and a telephone. Here, the content change process may be executed for all words (for example, including a general dialogue) uttered in the utterance process. For example, the control unit 22 indicates that the mobile terminal 11 is placed on the charging stand 12 provided at a place other than a specific place (for example, the home of the user to be interacted with), or the positional information acquired from the charging stand 12 or GPS When it is detected from a signal or the like, the content change process may be executed for all words spoken. At this time, all private information included in the spoken words may be replaced with fixed phrases or common words. For example, when the mobile terminal 11 is placed on the charging stand 12 provided outside the home of the user to be interacted with, the control unit 22 executes content change processing for all words spoken. . At this time, for example, the control unit 22 changes the utterance content in the general dialogue “Today is Mr. B's birthday” to “Today is a friend's anniversary”. By executing the content change process for all utterance contents including the general dialogue, it becomes possible to protect the personal information of the user who is the dialogue target more firmly.
