Embodiment 1
Based on FIGS. 1-6, the 1st Embodiment (Embodiment 1) of this invention is described.

[Outline of robot cleaner 10]
Based on FIG. 3, the outline | summary of the robot cleaner 10 is demonstrated. FIG. 3 is a schematic diagram illustrating an example of a situation in which the robot cleaner 10 operates. FIG. 3A is a schematic diagram showing a scene in which a mother gives a morning greeting to the robot cleaner 10, and FIG. 3B shows a scene in which a father gives a morning greeting to the robot cleaner 10. It is a schematic diagram, (c) is a schematic diagram showing a scene in which a mother greets the robot cleaner 10 when going out.

  The robot cleaner (reproducing device) 10 is a self-propelled cleaner that automatically cleans the floor. In particular, the robot cleaner 10 presents the content 7 recorded in the audio data 1 as the audio to the user by reproducing the audio included in the audio data (audio information) 1. Here, the above “content” includes individual information provided from an arbitrary information source (Internet, television broadcast, satellite broadcast, cable television, radio broadcast, etc.) such as news, weather information, route information, and regional information. It is composed of video, images, music, audio, text, characters, mathematical formulas, numbers, symbols, or combinations thereof.

  The robot cleaner 10 also has a function of communicating with the server 15 (which will be described in detail later with reference to FIG. 2), a function of recording an operation log, a function of detecting the remaining charge level, a function of outputting, and an image. It has a shooting function, a voice recognition function, a voice output function, and the like. Further, the robot cleaner 10 transmits a control signal to a home device (refers to a device placed in the home such as a television receiver, an air conditioner, a lighting device, a recording device, a fully automatic washing machine), and It also has a function to control household devices.

  It should be noted that functions equivalent to the functions provided by the robot cleaner 10 (particularly, the content recorded in the audio data 1 as the audio by reproducing the audio included in the audio data 1 as described below) 7) can also be realized by a mobile phone, a personal computer, a tablet terminal, or the like. That is, the device need not be the robot cleaner 10 as long as the device can input and output necessary information.

  As shown in FIG. 3A, when the mother (user) greets the robot cleaner 10 with “Good morning”, the robot cleaner 10 recognizes that the mother has started communication (the user has ) "And return a greeting saying" Mom, good morning ". And "Today's news is announced. Today's news is economic news 1-1, economic news 1-2, economic news 1-3, weather information 1-1, route information 1-1, regional information 1- 1, “Regional information 1-2”, the robot cleaner 10 provides a table of contents (title of the content 7) of the content 7 to be presented to the identified user (mother) in a predetermined order. To list).

  As shown in FIG. 3B, the robot cleaner 10 reproduces the sound included in the sound data 1, thereby presenting the content 7 recorded in the sound data 1 as the sound to the mother. When the father (user) greets the robot cleaner 10 with “Good morning”, the robot cleaner 10 recognizes that the father has started communication (the new user is “dad”. To identify). That is, the robot cleaner 10 recognizes that the content 7 can be presented to another user (dad) different from the user (mother).

  Then, the robot cleaner 10 performs a predetermined timing (a timing that does not give an unnatural impression to the user even if the playback is interrupted, a timing that the playback is ended up to the position of the audio data that can interrupt the playback, or any other arbitrary timing) After returning a greeting saying “Dad, good morning”, “New political user 2-1 will be added to today ’s news” and a new user (mother) will be specified. The new content 7 is added to the other user (dad) who has made the change and the predetermined order is changed.

  Here, as a user who can use the robot cleaner 10, a user (a father, a mother, and a daughter) registered in advance in the robot cleaner 10 is given priority. For example, in the example shown in FIG. 3B, a higher priority is given to the father than the mother (detailed later with reference to FIG. 4A). Accordingly, when the content 7 is presented to the mother, the content 7 can be presented to a father having a higher priority than the mother (the father is present in the range where the audio can be heard). When newly recognized), the robot cleaner 10 presents new content 7 (political news 2-1) in accordance with the user (dad) with a high priority. Further, the robot cleaner 10 changes the predetermined order so that the new content 7 in which the user with higher priority is interested is presented first.

  The robot cleaner 10 changes the predetermined order so that the contents 7 (economic news 1-3 and weather information 1-1) that both the father and the mother are interested in are presented first. Also good. If the audio data 1 in which the new content 7 is recorded has not yet been acquired at the time when the predetermined order is changed, the robot cleaner 10 acquires the new content 7 from the server 15.

  As shown in FIG. 3C, when the mother greets the robot cleaner 10 “I will go”, the robot cleaner 10 recognizes that the mother has finished communication (“mom”). Recognizes that the user has deviated from the user who is within the range where the voice can be heard), and returns a greeting saying “Mom, please go” at the predetermined timing. Then, the robot cleaner 10 changes the order of presenting the content 7 again so that the content 7 in which only the father is interested is presented. For example, the robot cleaner 10 removes the content 7 (regional information 1-1 or the like) that only the mother is interested in from the candidates for the content 7 that should be presented to the user, or the content 7 is all other content 7. The predetermined order is changed so as to be presented after being presented.

  As described above, unlike the conventional device that only reproduces a predetermined sound regardless of the user, the robot cleaner 10 changes the user (for example, when the content 7 is presented to the mother, the dad The content 7 to be presented can be dynamically acquired so as to adapt to the newly recognized presence of the. Moreover, the robot cleaner 10 can change the order of presenting the content 7 according to the dynamically acquired content 7. Therefore, the robot cleaner 10 can improve user convenience.

[Configuration of the robot cleaner 10]
Based on FIG. 1, the structure of the robot cleaner 10 is demonstrated. FIG. 1 is a block diagram showing a main configuration of the robot cleaner 10. In addition, in order to ensure the conciseness of description, the structure which is not directly related to this Embodiment is abbreviate | omitted from description and a block diagram. However, in accordance with the actual situation of implementation, the robot cleaner 10 may have the omitted configuration (the same applies to other block diagrams). As shown in FIG. 1, the robot cleaner 10 includes a communication unit 30a, a reception unit 31a, a transmission unit 32a, a storage unit 40a, a control unit 20a, a voice acquisition unit 21, a sequence change unit 22, a voice reproduction unit 23, and a user. An identification unit 24, a microphone unit 60, and a speaker unit 50 are provided.

  The communication unit 30a communicates with the outside via a communication network according to a predetermined communication method. It is only necessary to have an essential function for realizing communication with an external device (such as the server 15), and a communication line, a communication method, a communication medium, and the like are not limited. The communication unit 30a can use a communication method or a communication medium such as IEEE802.11 wireless communication or Bluetooth (registered trademark). The communication unit 30a includes a reception unit 31a and a transmission unit 32a.

  The receiving unit 31a receives the audio data 1 and the data management file 2 by communicating with the server 15 via a communication network according to a predetermined communication method. The receiving unit 31a outputs the received audio data 1 and data management file 2 to the audio acquiring unit 21. When the data transmission request 8 (referred to as information requesting the server 15 to transmit predetermined data) is input from the voice acquisition unit 21, the transmission unit 32a sets a communication network according to a predetermined communication method. Then, the data transmission request 8 is transmitted to the server 15.

  The storage unit 40 a is a storage device that can store the audio data 1 and the data management file 2. The storage unit 40a can be configured by, for example, a hard disk, an SSD (silicon state drive), a semiconductor memory, a DVD, or the like.

  The control unit 20a controls the various functions of the robot cleaner 10 in an integrated manner. The control unit 20 a includes an audio acquisition unit 21, an order change unit 22, an audio reproduction unit 23, and a user identification unit 24.

  When the user who can present the content 7 changes, the audio acquisition unit (selection unit) 21 selects at least one audio data 1 according to the changed user. Here, “when the user has changed” refers to a case where the number of users who can present the content 7 has increased, has decreased, and / or has been replaced. For example, as in the example shown in FIGS. 3A and 3B, when the content 7 is presented to the mother, the content 7 can be presented to the father (hereinafter referred to as “case”). A)). Alternatively, as in the example shown in FIGS. 3B and 3C, when the content 7 is presented to the father and the mother, the content 7 can be presented only to the father (hereinafter referred to as the following). , Referred to as “Case B”).

  Specifically, when user identification information 3 (referred to as information that can uniquely identify a user) is input from the user identification unit 24, the voice acquisition unit 21 acquires the data management file 2. Next, the voice acquisition unit 21 refers to the acquired data management file 2 and acquires (selects) the voice data 1 associated with the user identification information 3. For example, in the case A, the voice acquisition unit 21 refers to the data management file 2 and selects the voice data 1 associated with the user identification information (other user identification information) 3 for identifying “dad”. (Alternatively, voice data 1 in which user identification information 3 for identifying “mother” and user identification information 3 for identifying “dad” are both associated may be selected). Alternatively, in the case B, the voice acquisition unit 21 refers to the data management file 2 and selects the voice data 1 associated with only the user identification information 3 that identifies “dad”. That is, the sound acquisition unit 21 selects the sound data 1 in which the content 7 to be presented to at least one user included in the changed user is recorded.

  When the voice data 1 or the data management file 2 is already received from the server 15 and stored in the storage unit 40a, the voice acquisition unit 21 stores the voice data 1 or the data management file 2 in the storage unit. Select from 40a. When not yet received from the server 15 and stored in the storage unit 40a, the audio acquisition unit 21 transmits the data transmission request 8 to the server 15 via the transmission unit 32a, thereby the audio data 1 or the The data management file 2 is selected from the server 15 via the receiving unit 30.

  The audio acquisition unit 21 outputs the selected audio data 1 to the audio reproduction unit 23, and outputs the acquired data management file 2 to the order change unit 22. The voice acquisition unit 21 updates the data management file 2 according to the selected voice data 1, and stores the voice data 1 and the updated data management file 2 in the storage unit 40a.

  The voice acquisition unit 21 compares the data management file 2 managed in the server 15 with the data management file 2 stored in the storage unit 40a during the time period when the content 7 is presented, and the former voice data list. The missing voice data 1 is acquired from the server 15 and the unnecessary voice data 1 is deleted from the storage unit 40a so that the latter voice data list is the same (described later with reference to FIG. 4). Good (mirroring download).

  The order changing unit (changing unit) 22 changes the reproduction order 4 of the audio included in the audio data 1 selected by the audio acquiring unit 21 according to the order determination policy (predetermined policy) corresponding to the audio data 1. To do. Specifically, when the data management file 2 is input from the voice acquisition unit 21, the order changing unit 22 refers to the order determination flag included in the updated data management file 2 and indicates the order determination flag. The reproduction order 4 of the audio included in the audio data 1 is changed based on the order determination policy. Then, the order changing unit 22 outputs the playback order 4 to the audio playback unit 23. Details of the order determination policy will be described later.

  The audio reproducing unit (presenting means) 23 presents the content 7 recorded as audio to the user and other users according to the reproduction order 4 changed by the order changing unit 22. Specifically, when the audio data 1 is input from the audio acquisition unit 21 and the reproduction order 4 is input from the order changing unit 22, the audio reproduction unit 23 is included in the audio data 1 according to the reproduction order 4. The audio signal 5 a is generated so as to reproduce the sound to be reproduced, and the audio signal 5 a is output to the speaker unit 50. Thereby, the robot cleaner 10 can make a user listen to the said audio | voice.

  Note that the user can arbitrarily set a time period during which the sound reproduction unit 23 reproduces the sound (a time period during which the user can listen to the sound). Moreover, the audio | voice reproduction | regeneration part 23 can estimate the time slot | zone suitable for reproducing | regenerating the said audio | voice based on the information of a predetermined | prescribed life log or HEMS (home energy monitoring system). Further, when the robot cleaner 10 is provided with an illuminance sensor (not shown in FIG. 1), if it is detected that the electricity in the room is turned on, even if the sound reproduction unit 23 starts reproducing the sound, Good.

  The user identification unit (identification means) 24 identifies a user who exists in a range where sound can be heard. Specifically, when the audio signal 5b is input from the microphone unit 60, the user identification unit 24 analyzes the audio signal 5b, thereby generating a user who uttered the microphone unit 60 (in FIG. 3). In the example shown in (b), the robot cleaner 10 is identified as “Dad” who says “Good morning” to the robot cleaner 10, and the user identification information 3 that can identify the user is output to the voice acquisition unit 21.

  The method used by the user identification unit 24 to identify the user from the voice may be a known voice recognition technique. Moreover, the user identification part 24 may identify a user using methods other than identifying a user based on a speech recognition technique. For example, when the robot cleaner 10 includes a predetermined input interface (not shown in FIG. 1), the user identification unit 24 receives the input that can uniquely identify the user from the input interface, thereby May be identified. Furthermore, the user identification part 24 may identify a user by cooperating with a domestic device. For example, the user identifying unit 24 can identify the user by detecting that a predetermined household device located in the same room as the robot cleaner 10 is turned on.

  The microphone unit 60 is a microphone that collects ambient sounds, converts them into audio signals 5 b, and outputs the audio signals 5 b to the user identification unit 24. The speaker unit 50 is a speaker that outputs the sound represented by the audio signal 5 a based on the audio signal 5 a input from the audio reproduction unit 23. In addition, when the speaker which comprises the speaker part 50 can output multiplexed audio | voice, the robot cleaner 10 can reply with a voice | voice with respect to a user so that it may overlap with reproduction | regeneration of an audio | voice. For example, in the example shown in FIG. 3C, the robot cleaner 10 can output a reply “Mother, please go” superimposed on the reproduction of the sound.

[Configuration of Server 15]
Based on FIG. 2, the structure of the server 15 is demonstrated. FIG. 2 is a block diagram illustrating a main configuration of the server 15. As shown in FIG. 2, the server 15 includes a communication unit 30b, a reception unit 31b, a transmission unit 32b, a control unit 20b, a data acquisition unit 71, a data generation unit 72, a management file generation unit 73, an information transmission unit 74, and The storage unit 40b is provided.

  The server 15 is communicably connected to the robot cleaner 10 and sends predetermined data (voice data 1 and data management file 2) to the robot cleaner 10 in response to a data transmission request 8 from the robot cleaner 10. To be sent.

  The communication unit 30b communicates with the outside via a communication network according to a predetermined communication method. It is only necessary to have an essential function for realizing communication with an external device (such as the robot cleaner 10), and a communication line, a communication method, a communication medium, and the like are not limited. The communication unit 30b can use a communication method or a communication medium such as IEEE802.11 wireless communication or Bluetooth (registered trademark). The communication unit 30b includes a reception unit 31b and a transmission unit 32b.

  The reception unit 31b receives the data transmission request 8 from the robot cleaner 10 by communicating with the robot cleaner 10 via the communication network according to the predetermined communication method, and receives the data transmission request 8 from the data acquisition unit. To 71. In addition, the receiving unit 31 b receives the content 7 from an external device (for example, another server) and outputs the content 7 to the data acquisition unit 71. When the voice data 1 and the data management file 2 are input from the information transmission unit 74, the transmission unit 32b communicates with the robot cleaner 10 via the communication network according to the predetermined communication method, thereby the robot cleaner The audio data 1 and the data management file 2 are transmitted to 10.

  The control unit 20b controls the various functions of the server 15 in an integrated manner. The control unit 20b includes a data acquisition unit 71, a data generation unit 72, a management file generation unit 73, and an information transmission unit 74.

  When the data acquisition unit 71 acquires the data transmission request 8 from the robot cleaner 10 via the reception unit 31b, the data acquisition unit 71 acquires the content 7 from the external device via the reception unit 31b. The data acquisition unit 71 outputs the acquired content 7 to the data generation unit 72 and the management file generation unit 73. Here, as described above, the content 7 acquired by the data acquisition unit 71 is individual information provided from an arbitrary information source. For example, it may be an article acquired from a predetermined news site via the Internet, or may be audio data distributed from a predetermined content distribution server. In addition, the information submitter may supply the content 7 to the server 15 at any time.

  The data generation unit (first generation unit) 72 generates audio data 1 in which the content 7 is recorded by audio. For example, when an article acquired from a predetermined news site is input as the content 7 from the data acquisition unit 71, the data generation unit 72 reads out the article (a known speech synthesis method that converts character information into speech information). The voice data 1 is generated, and the voice data 1 is output to the information transmission unit 74. Alternatively, when the audio data distributed from a predetermined content distribution server is input as the content 7 from the data acquisition unit 71, the data generation unit 72 outputs the audio data to the information transmission unit 74.

  When the content 7 is input from the data acquisition unit 71, the management file generation unit (second generation unit) 73 is data in which at least one user identification information 3 that can uniquely identify a user is associated with the audio data 1. A management file (corresponding information) 2 is generated. The management file generation unit 73 outputs the generated data management file 2 to the information transmission unit 74.

  When the audio data 1 is input from the data generation unit 72 and the data management file 2 is input from the management file generation unit 73, the information transmission unit (transmission means) 74 receives the audio data 1 and the data via the transmission unit 32b. The data management file 2 is transmitted to the robot cleaner 10. When the management file generation unit 73 periodically generates the data management file 2 (at a predetermined interval), the information transmission unit 74 transmits the data management file 2 to the robot cleaner 10 at the predetermined interval. It's okay.

  The storage unit 40 b is a storage device that can store the audio data 1 and the data management file 2. The storage unit 40b can be configured by, for example, a hard disk, an SSD (silicon state drive), a semiconductor memory, a DVD, or the like, similar to the storage unit 40a described above.

[Configuration of data management file 2]
The configuration of the data management file 2 will be described with reference to FIG. FIG. 4A is a table showing an example of a priority table included in the data management file 2 as a table for defining information categories and viewing member priorities, and FIG. 4B is data of “economic news”. 5 is a table showing an example of a management file 2, and FIG. 6C is a table showing an example of a data management file 2 of “political news”. (D) is a table showing an example of the data management file 2 of “weather information”, (e) is a table showing an example of the data management file 2 of “route information”, and (f) is “region information”. It is a table | surface which shows an example of the data management file 2 of.

  As shown in FIG. 4A, the data management file 2 includes an “information category” (refers to a label that classifies content according to a predetermined standard) and a “viewing member” (the robot cleaner 10 can be used). As a user, a priority table that defines the priority order of each of the robot cleaners 10 (referred to as users registered in advance) is included. Here, in the priority table, in the “information category” column, “news 1” (category including economic news 1-1, economic news 1-2, economic news 1-3, FIG. 4 (see (b)), “news 2” (category including political news 2-1; see FIG. 4 (c)), “weather information 1” (see FIG. 4 (d)), “route information 1” (See (e) of FIG. 4) is set. In the priority table, “dad” (father), “mother” (mother), and “daughter” are set in the “viewing member” column in order from the member with the highest priority.

  As shown in FIGS. 4B to 4F, the data management file (corresponding information) 2 exists for each information category to which the content 7 belongs, and includes at least an order determination flag and an audio data list. The “order determination flag” is a flag indicating an order determination policy based on the case where the order changing unit 22 determines the reproduction order 4 (which will be described in detail later with reference to FIG. 5). The “audio data list” is a list of audio data 1 managed by the data management file 2 and includes an identifier of audio data, a delivery time, a viewing time limit, and a target person (user identification information 3).

  Here, it should be noted that the data management file 2 associates at least one user identification information 3 that can uniquely identify a user with the audio data 1. As shown in FIG. 4B, for example, the voice data 1 of “Economic News 1-1” is associated with user identification information 3 that identifies “mom”. Also, as shown in FIG. 4C, the voice data 1 of “political news 2-1” is associated with user identification information 3 that identifies “dad”. Further, as shown in FIG. 4D, the voice data 1 of “weather information 1-1” corresponds to user identification information 3 for identifying “dad”, “mother”, and “daughter”. It is attached.

  Therefore, as illustrated in FIGS. 3A and 3B, when the content 7 is presented to the mother, the content 7 can be presented to the father (case A). The voice acquisition unit 21 refers to the user identification information 3 included in the data management file 2 and is interested in a user (dad) having a high priority in the priority table (a user identifying “dad”). The audio data 1 in which the content 7 (political news 2-1) included in the information category having a high priority is recorded is selected. Or, as described above, the voice acquisition unit 21 is interested in both the father and the mother (user identification information 3 for identifying “dad” and user identification information 3 for identifying “mother”). You may select the content 7 (both matched) (economic news 1-3, weather information 1-1). In this case, the information category (weather information 1) including “economic news 1-3” has a higher priority than the information category (news 1) including “weather information 1-1”. “Economic news 1-3” may be presented to both parties earlier than “1-1” (but not limited to this).

[Method for determining playback order 4]
Based on FIG. 5, a method in which the order changing unit 22 determines the playback order 4 will be described. FIG. 5A is a time chart showing the playback order 4 determined when the order determination policy is not set, and FIG. 5B is determined when the order determination policy is “emergency”. 6 is a time chart showing a reproduction order 4; (C) is a time chart showing the playback order 4 determined when the order determination policy is “latest only”, and (d) is determined when the order determination policy is “viewing time priority”. 6 is a time chart showing the reproduction order 4; (E) is a time chart showing the playback order 4 determined when the order determination policy is “priority for latest distribution time”, and (f) is the playback order determined when a new genre is added. 4 is a time chart representing 4. FIG.

  As shown in (a) of FIG. 5, when nothing is set in the order determination flag included in the data management file 2 and the order determination policy (predetermined policy) is “normal”, the order change unit 22 determines the reproduction order 4 so that the audio included in the audio data 1 in which the content 7 is recorded is reproduced according to the order in which the content 7 is distributed. That is, in the example shown in FIG. 5A, “information B” is presented after “information A”.

  As shown in (b) of FIG. 5, when the “emergency” order determination policy is set in the order determination flag included in the data management file 2, the order change unit 22 determines the time when the content 7 is distributed. The reproduction order 4 is determined so that the content 7 with a short interval (period) between the (delivery time) and the time limit (viewing time limit) for viewing the content 7 is preferentially presented to the user. That is, in the example shown in FIG. 5B, “Information A” is presented after “Information B”.

  As shown in (c) of FIG. 5, when the “latest only” order determination policy is set in the order determination flag included in the data management file 2, the order change unit 22 displays the most recently delivered content. The playback order 4 is determined so that only 7 is presented to the user. That is, in the example shown in FIG. 5C, “information A” is not presented to the user, but only “information B” is presented.

  As shown in (d) of FIG. 5, when the order determination policy of “viewing time limit priority” is set in the order determination flag included in the data management file 2, the order changing unit 22 has the closest viewing time limit. The reproduction order 4 is determined so that the content 7 is preferentially presented to the user. That is, in the example shown in FIG. 5D, “Information A” is presented after “Information B”.
