  In the sound reproduction device of Patent Document 1, when the user causes the sound reproduction device to perform automatic music selection and automatic reproduction, the user music selection mode (S110 in FIG. 2 in Patent Document 1 and S213 in FIG. 5) is performed prior to that. Unless manually switched to the history search mode or the automatic music selection mode, automatic music selection and automatic reproduction are not performed at the next power-on (S101 in FIG. 2 and S201 in FIG. 5). In other words, the sound reproduction device of Patent Document 1 is to perform automatic music selection at the next power-on (S101 in FIG. 2 and S201 in FIG. 5) in the user music selection mode. The user needs to manually switch to the history search mode or the automatic music selection mode while the power is turned on.

  Also in the reproduction apparatus of Patent Document 2, when the user performs automatic music selection and automatic reproduction, the user needs to manually press the AUTO-PLAY key (S60 in FIG. 9 of Patent Document 2).

  It is an object of the present invention to provide a user with an appropriate timing even if the user does not manually operate the proposal instruction or when manual selection of content is possible, without manually switching the mode. To provide a content proposal device, a content proposal method, and a program capable of executing a content proposal.

  The content proposal device of the present invention has a content proposal means for proposing content to a user, and a time setting means for setting a proposal hold time until the next content proposal. The next content proposal is made after the proposal hold time elapses.

  The content proposal method of the present invention includes a content proposal step for proposing content to a user, a time setting step for setting a proposal hold time until the next content proposal, and after the content proposal, And the above-described content proposal step for making a content proposal.

  The program of the present invention causes a computer to function as each means of the content proposal device of the present invention.

  According to the present invention, the user can automatically receive a content proposal from the content proposal device at an appropriate timing without issuing a content proposal instruction manually or by uttering or switching to the content proposal mode.

  FIG. 1 is a schematic configuration diagram of an in-vehicle AV (Audio & Visual) device 10. The in-vehicle AV device 10 typically serves as a car navigation device. The input unit 11 includes a microphone, a touch panel, and a remote controller, and is operated by the user when the user issues a predetermined instruction to the in-vehicle AV device 10. The user's voice input from the microphone of the input unit 11 is converted into data recognized by the language analysis unit 12, and the processed data is sent to the agent processing unit 15. Input data other than voice is sent directly to the agent processing unit 15.

  The agent processing unit 15 includes a music search unit 16. The music search unit 16 searches for music based on a character DB (database) 26 described later and a music DB in the storage device 27. The output unit 19 includes a speaker and a display, and agent characters 60a to 60d (FIG. 5) are appropriately displayed on the display. The display normally serves as a touch panel of the input unit 11, and the user can touch the icon or button displayed on the display with a finger to perform a predetermined instruction or selection.

  The agent processing unit 15 generates speech data for reading a text other than the utterance of the agent character or the speech of the agent character, and sends it to the speech synthesis unit 18. The voice synthesizer 18 converts the voice data into a voice signal and emits the sound from the speaker of the output unit 19. An audio signal such as a music reproduction sound, a program audio of a tuner (not shown), and a video signal are directly sent to the output unit 19.

  The communication unit 21 can communicate with a mobile phone and a base station of DSRC (Dedicated Short Range Communication) by radio 22. The agent processing unit 15 sends transmission data to the radio 22 and receives reception data from the communication unit 21. The vehicle information detection unit 23 detects the current location using a GPS (Global Positioning System) signal and sends a detection signal to the agent processing unit 15.

  The character DB 26 stores images, sounds, and setting data associated with each agent character. The agent processing unit 15 uses the character DB 26 to operate the agent character on the display of the output unit 19 or outputs the utterance of the agent character being displayed on the display from the speaker of the output unit 19. The storage device 27 is equipped with a music database, a reproduction history, and an association list for extracting a music search keyword related to content preference associated with each agent character as audio data of each music. The character DB 26 can be stored in the storage device 27 together with the music database and the like.

  FIG. 2 is an explanatory diagram of the relationship between the music proposal execution time and the date and time of engine start of the user car in the music proposal method 35 (FIG. 3) implemented in the in-vehicle AV device 10. The music proposal method 35 determines the scheduled date and time of music proposal as 10:10 on February 11, 2006 at the time of the previous music proposal. When the engine is started on February 9, 2006, 13:00 and on February 11, 2006, 9:00, the current time is before the scheduled date and time, so the music is not proposed. However, when the engine is started on February 11, 2006 at 13:50, the music proposal date is February 10, 2006, 10:10, and the music proposal is executed.

  The music proposal method 35 updates the scheduled date and time for the next music proposal to 13:55 on March 11, 2006 after the music proposal. On March 11, 2006, 13:55, the next scheduled date and time is the date and time when a predetermined time has passed since the previous music proposal execution end time, and the predetermined time may be determined by the user himself / herself. The in-vehicle AV device 10 may determine an appropriate value. Note that the next scheduled date and time March 11, 2006 13:55 is the time after the passage of January, assuming that the current end time of the music proposal method 35 is February 11, 2006 13:55. is there.

  When the engine is started on March 11, 2006 at 13:50, since the scheduled date and time is before March 11, 2006 at 13:55, the music proposal method 35 is not activated. However, when the engine is started on March 11, 2006 at 15:15, the music proposal is scheduled since March 11, 2006, 13:55 on March 11, 2006. Thus, if each start date and time has passed the scheduled date and time of the music proposal, the music proposal is performed, and the scheduled date and time of the next music proposal is determined at the end.

  In the explanatory diagram of FIG. 2, music proposal is made only when the engine is started, but if the current time becomes the scheduled date and time of music proposal during the engine operation period from the engine start to the next engine stop. As soon as possible, the music proposal by the music proposal method 35 may be performed. Further, instead of when the engine is started, the time when the vehicle-mounted AV device 10 is turned on or when a predetermined event occurs may be compared with the scheduled date and time of music proposal. Furthermore, the date and time of the next music proposal may be determined at a different time from the end of the music proposal in the music proposal method 35, for example, when the engine is stopped.

  FIG. 3 is a flowchart of the music proposal method 35. The music proposal in the flowchart is limited when the engine is started in the user's car. In S36, it is checked whether or not the current time, that is, the current engine start time has passed the music proposal scheduled date and time. If not, the music proposal method 35 is immediately terminated, and if it has passed, the process proceeds to S37. It should be noted that when the engine is started, the user uses the same meaning as when the user starts driving the automobile.

  In S37, the music proposal start screen is displayed on the display (the output unit 19 in FIG. 1). In S38, the proposed music is searched. FIG. 4 is an example of a screen displayed on the display when S37 and S38 are executed.

  Strictly speaking, the search in S38 is a search for semi-automatic music selection, not automatic music selection. That is, in the music suggestion method 35, as can be seen from the selection buttons “listen now”, “listen later” and “do not listen” in FIG. Ignore it and do not force playback, and get the user's consent. Only when there is an approval, that is, when the user selects “listen now” or “listen later”, the reproduction is performed, and the automatic music selection is not performed.

  The search criteria for music selection in S38 can be set arbitrarily. Statistics of the playback date / time and attributes (genre, artist, album name or song name) of the music that the user has played in the past are kept, and those that match the user's taste based on the statistics, which I have often heard before, The search criteria can be those that you no longer listen to, that you have recently heard frequently in the vicinity of the current location or the current time zone, or that you have heard once in the past.

  In S39, the music found as a result of the search in S38 is proposed to the user. FIG. 5 shows an example of a screen displayed on the display at this time. In the screen, the proposed music has a music name: AABBCC and an artist name: aabbcc. The user can select “Listen Now”, “Listen Later”, “Do Not Listen”, and “Cancel Proposal” from the screen of FIG. The selection is performed by, for example, touching each selection button on the touch panel with a user's finger or speaking by the user.

  If the user selects “Listen now” on the user selection screen in FIG. 5 (S40 right → S48 right), the process immediately proceeds to S55, and the proposed music is reproduced.

  When the user selects “Do not listen” on the user selection screen in FIG. 5 (S40 positive → S47 NO), S39 is performed again. FIG. 6 shows an example of a screen displayed on the display at this time.

  If the user selects “Cancel proposal” on the user selection screen of FIG. 5 (No in S40 → S48 correct), the process proceeds to S56, the date and time of the next music proposal is decided, and the music proposal method 35 is terminated. .

  When the user selects “listen later” on the user selection screen of FIG. 5 (S40 forward → S48 NO), the process proceeds to S49, and the reproduction of the proposed music is reserved. FIG. 7 shows an example of a screen displayed on the display at this time. Thereafter, when the user gives an instruction to play the reserved music (S50 right), the process proceeds to S55 to play the proposed music.

  When the reproduction of the current proposal music in S55 is completed, the process proceeds to S56, the date and time of the next music proposal is decided, and the music proposal method 35 is finished. The date and time of the next music proposal is stored in a non-volatile storage device that retains the memory even when the engine is stopped.

  The music proposing method 35 is supposed to be executed when the engine is started. However, during the operation after the engine is started, the determination of S36 is performed at regular time intervals, and as soon as the determination of S36 becomes positive, the process proceeds to S37. Also good. In the music proposing method 35, the music proposing method 35 is ended only by reproducing one piece of music proposed to the user in S55. However, after the execution of S55, a predetermined condition (for example, the total number of the current proposed music) If the number of reproductions or the reproduction time is less than or equal to a predetermined value), it is possible to return from S55 to S39.

  Furthermore, in the music proposal method 35, only one song can be reserved for playback, but the user asks the user whether or not he / she wishes further music proposal between S49 and S50, and the user proposes further music. If desired, the process can return to S39.

  FIG. 8 is a block diagram of the content proposal device 70. The above-described in-vehicle AV device 10 is a specific example of the content proposal device 70. The content proposal device 70 is not limited to a vehicle-mounted type, and may be a type that is deployed indoors, particularly at home, or a portable type (including a pocket type and a palmtop type). The content proposal device 70 may be incorporated as an additional function in a mobile communication terminal or a mobile information terminal, not as a dedicated device.

  The content proposal device 70 includes content proposal means 71 and time setting means 72. The content proposing means 71 proposes content to the user. The time setting means 72 sets the proposal hold time until the next content proposal. The content proposal means 71 proposes the next content after the proposal hold time elapses after the content proposal.

  The content is typically music, but may be video content or audio content other than music. The content may be, for example, a radio program, a television program, an Internet site, a book, a movie ticket, a destination, a route, a travel pack, a restaurant, or a learning course.

  The content proposed by the content proposing means 71 is typically a reproduction target when it is a music piece, but is subject to purchase, download, or display route depending on the content. Things can be used. The user is free to accept or reject the content proposal proposed by the content proposal means 71. In the typical content proposal device 70, even when the user accepts the content proposal, the user can immediately select whether to start the processing such as reproduction or reserve the processing such as reproduction and perform the processing later. ing. In the preferred content proposal device 70, the user can arbitrarily select whether to execute or end the next content proposal after accepting or rejecting the first content proposal from the content proposal means 71. ing.

  The time setting means 72 may set the proposed suspension time to a time designated by the user or may be set automatically. In the case of the automatic setting of the proposed hold time, the time setting means 72 can set the analysis of the indoor situation, outdoor situation, driving situation, and / or user of the automobile as a setting factor. Further, preferably, the time setting means 72 may change the proposal hold time based on the change of the setting factor after the proposal hold time is set once and before the next content proposal is performed.

  These various situations are used as judgment materials for whether or not the user wants to propose content such as music, and if it can be judged that the atmosphere has been established, the suggestion hold time is set at the end of the content proposal. If the setting is set to be shorter or the change before the next content proposal is implemented, the proposal is shortened so that the implementation of the content proposal is accelerated (including the immediate execution of the shortening). The holding time is lengthened at the setting at the end of the content proposal, or is extended so that the implementation before the next content proposal is extended so that the implementation of the next content proposal is extended.

  For example, the indoor conditions of a car include whether the passenger's conversation is playing, is interrupted, whether the passenger has children etc. and is busy taking care of it, is currently listening to the radio, etc. is there. The outdoor situation of an automobile includes the outdoor environment and the outdoor traffic situation. The outdoor environment includes, for example, temperature, atmospheric pressure, humidity, wind speed, wind direction, solar radiation, and / or weather. As for the traffic situation, for example, it is possible to know whether the traffic flow is smooth or congested from the vehicle speed or the like.

  The driving situation of a car is, for example, whether it is running on a road with many steering operations or acceleration / deceleration, that is, a busy road, or a certain time or more while maintaining a constant speed, that is, a relatively idle period of driving operation, etc. is there. The current location is a place near a certain famous place, a point where the sea or a mountain is seen in front of the traveling direction, an expressway, or a road with few intersections. In addition, although the same situation may overlap with the outdoor situation, the driving situation of the car, or the current location of the car, it is sufficient that the same situation is grasped as belonging to any one of them. . In short, the proposal hold time is determined so that the content proposal is executed at a time when it is not bothered by the driver and is appreciated by the driver.

  The user analysis is, for example, a user who frequently listens to music while traveling, a user who uses TV, DVD, or radio more frequently than music, or always plays only the same CD (music). This is an analysis of whether the user is a user, a user whose driving time is concentrated in which time zone, or a user who drives for many hours every day.

An example of the relationship between the analysis of the user and the length of the proposal hold time when the content is a song and the song proposed by the content proposal device 70 is reproduced is as follows. The shorter the proposal hold time, the more frequently music proposals are made.
(A) If the user frequently listens to music while traveling, the user estimates that there is a piece of music he wants to listen to, and increases the proposal hold time.
(B) If the user uses TV, DVD, or radio more frequently than music, the proposal hold time is lengthened.
(C) If the user always reproduces only the same CD (music), the proposal hold time is shortened.

(D) If the user is driving frequently at night, the user is tired at night, and the user predicts that it will be troublesome to select the music by himself, so that the proposal hold time is shortened.
(E) If the user is driving for hours every day, the suggestion hold time is shortened by predicting that driving tends to be ruined.

  An example of the relationship between various factors other than the analysis of the user and the proposal hold time is as follows. When the conversation between the passengers is frequent as the indoor state of the automobile, the proposal hold time is lengthened, and when the conversation between the passengers is small, the proposal hold time is shortened. During the driving period in which acceleration / deceleration is frequently repeated or the steering wheel operation is frequently performed as the driving situation, the content proposal hinders the driver's attention, so the proposal holding time is lengthened.

  The proposal hold time may not be set immediately after execution of the current content proposal and processing (eg, reproduction) for the content proposal. It may be performed when a predetermined event occurs, or once set, it may be reset (extended or shortened) or canceled in response to the predetermined event.

  Preferably, when the proposal holding time has elapsed while the operation of the content proposal device 70 is stopped, the content proposal means 71 performs the content proposal after the next operation of the content proposal device 70 is started. The operation start of the content proposal device 70 is, for example, when the user turns on the power of the content proposal device 70 or when the engine of the automobile on which the content proposal device 70 is mounted is started.

  Preferably, the content proposing means 71 receives a reproduction interruption instruction from the user during the reproduction period of the content related to the content proposal and does not accept a reproduction resumption instruction within the proposal holding time, after the suggestion holding time has elapsed. When the content is proposed, the content interrupted by the reproduction interruption instruction is proposed.

  In this way, the content proposal device 70 can implement the content proposal at a nifty timing even if the user does not instruct the content proposal. When the content proposal device 70 is mounted on an automobile and the occupant is one driver, the driver can produce a space as if there is a passenger and the passenger is helping to propose content.

  FIG. 9 is a flowchart of the content proposal method 80. The aforementioned music proposal method 35 (FIG. 3) is a specific example of the content proposal method 80. The music proposal method 35 described above is to be executed when the automobile engine is started. However, the content proposal method 80 is not limited to when the engine is started, and periodically after the engine is started at regular time intervals. Regardless of whether it is an in-vehicle type or a non-in-vehicle type disc, it may be executed at regular intervals during the power-on period when the content proposal device is turned on.

  In S81, it is determined whether or not the proposal hold time has elapsed after the previous content proposal. In the first execution of S81, the proposal hold time is a default value. If the determination result in S81 is positive, the process proceeds to S82, and if not, the content proposal method 80 is terminated.

  In S82, content is proposed to the user. In S83, a proposal hold time until the next content proposal is set.

  The content proposal method 80 executes each function of the content proposal device 70 as steps, and a specific example of the function of the content proposal device 70 can be directly applied as a specific example of the steps of the content proposal method 80. The function of the content proposal unit 71 corresponds to the processes of S81 and S82, and the function of the time setting unit 72 corresponds to the process of S82.

  The program to which the present invention is applied causes a computer to function as each means of the content proposal device 70. Another program to which the present invention is applied causes a computer to execute each step of the content proposal method 80.

  Although the present invention has been described with respect to various specific embodiments, the present invention is not limited to this, and each component in the various specific embodiments is modified (including deletion) without departing from the gist of the invention. And can be materialized. Various inventions can also be formed by replacing constituent elements between various specific forms or combining a plurality of constituent elements in various specific forms.
