DESCRIPTION OF SYMBOLS 300 Music playback apparatus 301 Episode period setting part 302 Episode period place information acquisition part 303 Living / habitation list generation part 304 Position information acquisition part 305 Music reproduction list generation part 306 Music reproduction part 307 Destination candidate presentation part

In one aspect of the present invention, a music playback apparatus, a music information holding unit that holds music information including music attribute information, an episode period setting unit that sets an episode period based on user-specific information, Living and living list generation for generating living and living list information, which is information relating the episode period and location information corresponding to the episode period, and the episode period and location information acquiring means for acquiring the place information corresponding to the episode period Music reproduction for generating a music reproduction list of music related to the life residence list information corresponding to the position information using the means, position information acquisition means for obtaining position information, and the position information and the life residence list information A list generation unit; and a music reproduction unit that reproduces music based on the music reproduction list.

Specifically, the above-described music reproducing device can be applied to a device capable of sequentially acquiring position information, such as a navigation device. The music playback device holds music information including music attribute information in advance. Here, the music attribute information refers to information such as a music release date and a genre.

The episode period setting means sets the episode period based on the user's specific information (for example, the date of birth) acquired by a predetermined method (for example, an input operation). Here, the episode period refers to a period divided into a plurality of user growth processes. For example, the episode period is based on an era such as “elementary school age”, “junior high school age”, “working person”, etc. To do. As described above, the episode setting means sets an episode obtained by dividing a human growth process into a plurality of times.

And the episode period location information acquisition means acquires the location information corresponding to the episode period. As an acquisition method, there is an input operation by a user. The living and living list generating means generates living and living list information in which the episode period set by the music setting means and the place information acquired by the episode period place information acquiring means are associated with each other.

The position information acquisition means acquires position information of the music playback device itself. The music reproduction list generating means specifies the living list information corresponding to the position information acquired by the position information acquiring means, generates a music reproduction list of the music information related to the episode period of the living list information, and plays the music The means reproduces the music based on the music reproduction list.

As described above, the music reproducing device sets a plurality of periods for the user's past period, acquires place information corresponding to the set period, and associates the set period with the place information. By generating the list information, a music playback list for a set period (episode period) corresponding to the position of the music playback device can be generated and played based on the music playback list. The song of the corresponding episode period will be played, and the user's memory and experience will be recalled, and the user can enjoy emotions such as “Energy”, “Relax” and “Exhilaration”.

In one aspect of the music playback device, the episode period setting means sets based on music evaluation. In this case, the music reproducing device can generate the music list according to the subdivision degree of the episode period by setting the episode period based on the music evaluation.

In another aspect of the music playback device, the episode period setting unit subdivides the episode period hierarchically, and the music playback list generation unit generates a music playback list according to the level of the episode period hierarchy. Is generated. In this case, the episode period setting means stratifies the episode period based on the music evaluation. For example, for an episode period in which many songs that can be judged to have a high song evaluation, such as the number of playbacks being equal to or greater than a predetermined value, are included, the hierarchy level is set deep. Then, if the music reproduction list generating means changes the number of songs to be selected according to the hierarchy level, the music corresponding to the episode having a deep hierarchy level is preferentially included in the music reproduction list, On the other hand, clear memories and experiences can be recalled, and emotions such as “Energy”, “Relax” and “Exhilaration” can be enjoyed.

In addition, the music reproduction list generating means preferentially includes the music corresponding to the episode having a deep hierarchical level in the music list even when the hierarchical level is weighted for the music evaluation, so that a clear memory or Experiences can be recalled and emotions such as “Energy”, “Relax” and “Exhilaration” can be enjoyed.

As an example of music evaluation, for example, the evaluation may be made higher by weighting the number of reproductions and the number of requests as the hierarchy becomes deeper. Thereby, the music reproducing device can reflect the user's intention more faithfully.

In another aspect of the music playback device, the episode period setting means resets the episode period based on the music evaluation or the number of times of driving to a place corresponding to the episode period. Even in this case, the music reproducing device can include music that matches the user's preference in the music list by changing the priority ratio for selecting music according to the hierarchical level.

In another aspect of the music playback device, the music playback list generation unit generates a music playback list based on a result of weighting the hierarchical level for the music evaluation of each music. In this case, the music playback device uses the result obtained by weighting the depth of the hierarchical level of the episode corresponding to the music for the music evaluation (number of times played, information input by the user, etc.) in the music playback list. Decide which songs to include. As a result, the music playback device can generate a music playback list that more accurately reflects the user's intention.

In another aspect of the music reproducing device, the apparatus further includes destination candidate presenting means for presenting a location corresponding to the music being arbitrarily reproduced. In this case, the music playback device presents the location of the episode corresponding to the music being played back as a candidate drive destination, and when the user has not determined the destination, A place that can be a place can be presented as a destination place candidate.

In another aspect of the music reproducing device, the living and living list information includes range information corresponding to the location information, and the range information is in accordance with a degree of dispersion of the location information location corresponding to each episode. Then, the music reproduction list generation means refers to the range information of the living and living list information, and specifies the living and living list information corresponding to the position information. As a specific example of determining the range information according to the degree of dispersion, if the location in the living and living list information is relatively wide (such as “Hokkaido” or “Kyushu”), The reference range is large, and conversely, in the case of a narrow range (the degree of dispersion is small) in the same city, the reference range is reduced. According to this, when the music reproducing device refers to the above range information and specifies the episode corresponding to the position information, the range of the location corresponding to the episode period is too wide, so that the plurality of episodes are at the same position. It can be avoided that the position corresponding to the episode period is limited, or the position corresponding to the episode period is limited due to the narrow range of locations corresponding to the episode period.

In another aspect of the above music playback device, the music playback device further includes route search means for searching for a route, wherein the music play list generation means includes two locations on the route corresponding to episode periods, If there is no place corresponding to the episode period in the section between the two places on the route, the section displays a music playlist of the songs in the episode period between the episode periods corresponding to the two places on the route. Generate.

In this case, the music playback device allows the episodes corresponding to the two places when the section between the two predetermined places is located in the section even if the section does not correspond to any episode. Since a music playlist for episodes is generated and music is played based on the music playlist, songs in consecutive episode periods will be played back. You can enjoy feelings such as “exhilarating”.

In another aspect of the present invention, there is a music playback method performed by an apparatus that holds music information including music attribute information, the episode period setting step of setting an episode period based on user-specific information, An episode period location information acquisition step for acquiring location information corresponding to an episode period, and a life residence list generation step for generating life residence list information, which is information relating the episode period and location information corresponding to the episode period And a position information acquisition step of acquiring position information, and a music reproduction list for generating a music reproduction list of music related to the life and residence list information corresponding to the position information using the position information and the life and living list information A generation step and a music reproduction step of reproducing the music based on the music reproduction list.

Even with the above-described music playback method, a plurality of periods are set for the growth process of the user, place information corresponding to the set period is acquired, and living list information in which the set period is associated with the place information Is generated, and a music playback list related to the set period (episode period) corresponding to the position of the music playback device is generated and played based on the music playback list. The song will be played back, and the user's memory and experience will be recalled, and the user can enjoy emotions such as “energetic”, “relaxed”, and “exhilarating”.

In another aspect of the present invention, there is provided a music playback program that is executed by an apparatus that includes a computer and stores music information including music attribute information, and sets an episode period based on user-specific information. Means for acquiring place information corresponding to the episode period, and means for acquiring the place of living list that is information relating the episode period and the place information corresponding to the episode period.

[Music playback method]
Next, a music reproduction method will be described. Here, the music reproduction method is to set an episode period based on information input by the user, acquire location information corresponding to the episode period, and associate the episode period with the location information. This refers to a method of generating list information, generating a music playback list based on episodes at locations related to the position of the music playback device 300, and playing back music information based on the music playback list.

In the music playback device 300, the episode period setting unit 301 sets a plurality of episode periods based on user-specific information (birth date information, etc.). Then, the episode period location information acquisition unit 302 acquires episode period location information, which is location information related to the episode period.

The living and living list generating unit 303 generates living and living list information in which the episode period and the episode period place information are associated with each other. In addition, the living and living list generating unit 303 separately includes the range information of the episode period place information as the living and living list information by an input operation or the like.

The position information acquisition unit 304 acquires the position information of the music playback device 300 in a state where the above-mentioned living and living list information is held, and the music playback list generation unit 305 has location information corresponding to the position information. The living / residenting list information is searched, and a reproduction list of music information at the time of the episode of the searched living / residenting list information is generated and registered. Then, the music playback unit 306 plays back music based on the music playback list.

As described above, the music reproducing device 300 identifies the user's episode period based on the user's unique information such as the date of birth, acquires the location information corresponding to the episode period, the episode period, the location Living and living list information associated with the information is generated, a music reproduction list within the episode period of the location information regarding the position of the music reproducing device 300 is generated, and the music is reproduced based on the music reproduction list.

According to this, since the music reproducing device 300 generates the living and living list information in which the episode period and the place corresponding to the episode period are associated with each other, the music reproducing device 300 corresponds to the episode period related to the position of the music reproducing device 300. Can be provided.

Generally, a person's growth process includes a stage of forming a preference for the person. At the same time, in this growth process, information on episodes and related places is stored as human memory. In particular, the place where you lived or the place where you lived is stored as a user's memory. This long-term user response is effective.

By capturing information in line with the user's growth process and providing the optimal music along with the movement process (location movement), the user is reminded of the memory and is energized, relaxed, and refreshed. ”And other emotions.

When the episode period as shown in FIG. 3 is associated with the location of the episode period, as shown in FIG. 5, the music playback device 300 is located at the point P1 of “G capital H ward”. When it is, the music playback device 300 generates a music playback list including music related to the period of “working person 2” which is an episode corresponding to “G capital H ward”. Similarly, when the music playback device 300 is located at the point P3 that is the point of “A prefecture B city”, the music playback device 300 is in the period of “children to elementary school second semester” that is an episode corresponding to “A prefecture B city”. A music playlist composed of music related to is generated. Note that, as described above, when episodes having different levels are included, songs having a deep level may be preferentially incorporated into the reproduction list.

And when it is located at the point P2 which is the point of “X prefecture Y city” which is a place not included in the living and living list information, it is adjacent to the episode corresponding to the music played immediately before For example, a song reproduction list for an episode is generated, and a song is reproduced based on the song reproduction list.

[Music playback process]
Below, the procedure of a music reproduction process is demonstrated using the flowchart shown in FIG. This process is realized by the system controller 20 of the music playback device 300 executing a program prepared in advance.

First, the input unit 60 acquires information such as the date of birth via a predetermined input device (for example, a touch panel or a voice recognition device) (step S1).

Then, the current time is acquired using the timer function provided in the music playback device 300 (step S2). Then, the episode period setting unit 301 sets a plurality of episode periods based on the user specific information (step S3). And the episode period location information acquisition part 302 acquires the location information corresponding to an episode period by input operation etc. by a user (step S4). Then, the living and living list generation unit 303 generates living and living list information (step S5).

Then, the position information acquisition unit 304 acquires the position information of the music playback device 300 (step S6), and when it is necessary to generate a music playback list, such as when the music playback list is not generated (step S7; Yes). Then, a music reproduction list based on the episode of the living and living list information having the location information corresponding to the position information is generated (step S8). Then, when the music reproduction unit 306 reproduces the music based on the music reproduction list (step S9) and ends the music reproduction device 300 by turning off the power (step S10; Yes), the music reproduction process is terminated.

[Stratified episode period]
In addition, the episode period setting unit 301 determines the hierarchy for the certain period when the song evaluation for a certain period (for example, the first semester of elementary school) within a predetermined episode period exceeds a predetermined threshold. Subdivided. Here, the music evaluation refers to the number of reproductions, evaluation information input by the user, and the like.

According to this, if the music reproduction list generation unit 305 changes the number of songs to be selected according to the hierarchy level, the music corresponding to the episode having a deep hierarchy level is preferentially included in the music reproduction list. Thus, clear memories and experiences can be recalled to the user, and emotions such as “goodness”, “relaxation” and “exhilaration” can be enjoyed.

In addition, the music reproduction list generation unit 305 may generate a music reproduction list based on the result of weighting the hierarchical level with respect to the music evaluation (for example, the number of reproductions and the number of requests) of each music. Also in this case, the music reproduction list generation unit 305 preferentially includes the music corresponding to the episode having a deep hierarchical level in the music reproduction list, and the user is reminded of clear memories and experiences. ”,“ Relax ”and“ Exhilaration ”.

For example, when there are a plurality of episodes corresponding to a predetermined location, the music playback device 300 may include a music playback list with priority given to a song related to an episode at the deepest hierarchical level among the episodes corresponding to the location. It becomes possible, and the music reproduction list reflecting the user's intention more faithfully can be generated.

Also, the episode period setting unit 301 may subdivide when the number of times of driving to the place corresponding to the episode is equal to or greater than a predetermined threshold.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. FIG. 7 shows a schematic configuration of a music playback device 300a according to the second embodiment. In addition, the same code | symbol is attached | subjected to the component same as the music reproduction apparatus 300 of 2nd Example shown in FIG. 7, and the description is abbreviate | omitted.

The music playback device 300a in the second embodiment further includes a “destination candidate presentation unit 307” in the music playback device 300 of the first embodiment.

The destination candidate presenting unit 307 identifies the episode corresponding to the release time of the music being played back by the music playing unit 306 using the living and living list information, and presents the location information corresponding to the episode as the drive location. To do.

Accordingly, the music reproducing device 300a according to the second example corresponds to the release time of the music being reproduced using the living and living list information described in the first example by causing the destination candidate presenting unit 307 to function. An episode is specified, and a location corresponding to the episode is presented as a destination location candidate.

In this case, the music playback device 300a presents the location of the episode corresponding to the music being played back as a drive destination candidate site, and when the user has not determined the destination, A place that can be a destination can be presented as a destination place candidate.

Also, the music playback device 300a presents, as destination candidates, those whose distances from the current position (position of the music playback device 300a) to the user's registered location are close. When the distance from the current position to the location of the user registered in the list is more than a certain value, the music playback device 300a displays a plurality of candidates. Then, the music reproducing device 300a narrows down and displays candidates as it approaches one of the candidate locations.

The location related to the episode corresponding to the release time of the music being played is likely to be suitable as a drive destination for the user, so that the music playback device 300a has the episode corresponding to the music being played back. By presenting a place as a drive destination candidate place, a user can present a desired drive destination.

[Play music compatible place presentation process]
Below, the procedure of the reproduction music corresponding place presentation processing will be described using the flowchart shown in FIG. This process is realized by the system controller 20 of the music playback device 300a executing a program prepared in advance.

First, the input unit 60 acquires information such as the date of birth via a predetermined input device (for example, a touch panel or a voice recognition device) (step S11).

Then, the current time is acquired using the timer function provided in the music playback device 300a (step S12). Then, the episode period setting unit 301 sets a plurality of episode periods based on the user specific information (step S13). And the episode period location information acquisition part 302 acquires the location information corresponding to an episode period by input operation etc. by a user (step S14). Then, the living and living list generation unit 303 generates living and living list information (step S15).

Then, in response to the input operation by the user, when the music reproducing unit 306 is reproducing the music (step S16), the destination candidate presenting unit 307 releases the music using the living and living list information. The episode corresponding to the time is identified, the location corresponding to the episode is presented (step S17), and the process ends.

As described above, the music playback device 300 includes a music information holding unit that holds music information including music attribute information, an episode period setting unit that sets an episode period based on user-specific information, and an episode period. Episodic period location information acquisition means for acquiring corresponding place information, life and residence list generation means for generating life and residence list information that is information relating the episode period and location information corresponding to the episode period, and position information Using the position information acquisition means to acquire, the music reproduction list generation means for generating a music reproduction list of music related to the life residence list information corresponding to the position information, using the position information and the life residence list information; Music playback means for playing back music based on the play list.

As described above, the music reproducing device 300 sets a plurality of periods for the growth process of the user, acquires the location information corresponding to the set periods, and lives that associates the set periods with the location information. By generating the list information, a music playback list for a set period (episode period) corresponding to the position of the music playback device is generated and played based on the music playback list, so that the episode corresponding to the position of the music playback device The music of the period will be played back, and the user's memory and experience will be recalled, and the user can enjoy emotions such as “Energy”, “Relax” and “Exhilaration”.

In addition, the music reproduction device 300 includes range information corresponding to the location information in the life and residence list information, and the range information is determined according to the degree of dispersion of the location of the location information corresponding to each episode, The music reproduction list generating means refers to the range information of the living and living list information, and specifies the living and living list information corresponding to the position information.

An example of determining the range information according to the degree of dispersion is shown in FIGS. 10 (a) and 10 (b). As shown in FIG. 10 (a), when the episode corresponding places L1 to L5 which are places corresponding to an episode of a certain user are relatively dispersed, the music reproducing device 300 uses the living and living list information corresponding to each episode. The range information ranges A1 to A5 are set larger. Also, as shown in FIG. 10B, when the episode correspondence places L6 to L10 of other users are not so dispersed, the music reproducing device 300 displays the range information of the living and living list information corresponding to each episode. The range A6 to A10 is set smaller.

According to this, when the music reproducing device 300 refers to the range information and specifies the episode corresponding to the position information, the range of the location corresponding to the episode period is too wide so that a plurality of positions can be obtained. It is possible to avoid that the position corresponding to the episode period is limited due to the fact that it corresponds to the episode period or that the range of the location corresponding to the episode period is too narrow.

[Other embodiments]
In the above-described embodiment, the case of hierarchization based on the music evaluation has been described, but the present invention is not limited to this, and the episode period is subdivided based on the music evaluation without hierarchization. Also good. In this case, the music playback device 300 can generate a music playback list according to the degree of subdivision. For example, the music playback device 300 may preferentially include songs in an episode period with a high degree of subdivision (short episode period) in the playlist.

In the above-described embodiment, the music reproducing device 300 specifies the living house list information corresponding to the position information acquired at predetermined intervals, and generates the music playing list related to the episode of the living house list information. However, the present invention is not limited to this, and as a result of the route search performed by the music reproducing device 300, there is corresponding living and housing list information for two points in the route, and the position between the two points corresponds to the point. When there is no living and housing list, a song reproduction list of episodes related to the interval between the two episodes may be generated for a section having no corresponding living and living list information.

For example, as shown in FIG. 9, in the case where the route R1 is set, the section including the point P5 corresponds to the episode of “elementary school”, the point P6 corresponds to the episode of “high school”, and includes the point P5. In a case where none of the episodes is supported, the music playback device 300 generates a playlist of music related to the episode of “junior high school” that is an episode between “elementary school” and “high school” in the above section, and Play the music in the playlist.

According to this, when the section between two points having a corresponding episode in the route does not correspond to any episode but is located in the section, Since a music playback list of episodes between episodes in two places is generated and music is played back based on the music playback list, music in continuous episode periods is played back, and the user is more energetic. And "relaxation" and "exhilaration" can be enjoyed.

In the above-described embodiment, the case where an episode at a predetermined time is associated with the location of the episode has been described. However, the present invention is not limited to this, and a plurality of locations may be defined in the same episode. For example, an episode of “working person” may be associated with an address or associated with a work location.

In the above-described embodiment, a case has been described in which a certain long-term episode is associated with the location of the episode. However, the present invention is not limited to this, and a temporary event (for example, summer vacation, birthday, etc.) ) May be an episode.

In the above-described embodiment, the case where the position information acquisition unit 304 specifies the position of the music playback device 300 using the GPS receiver 18 has been described. However, the present invention is not limited to this, and predetermined position information is obtained.

Although not particularly described in the above-described embodiment, when a plurality of people use the vehicle on which the music playback device 300 is mounted, the living location list information of the plurality of people is held and the current position of the vehicle is stored. The episode is changed at a relative distance between and a music reproduction list based on the episode is generated. For example, the music playback device 300 generates a music playback list of episodes of the location of each person's living and living list information that is closest to the current position of the vehicle, and there are a plurality of locations of the living and living list corresponding to the current position of the vehicle. In this case, a music reproduction list in which episodes of the living and living list are mixed is generated.

In the above embodiment, the case where the range information is included in the living and living list information has been described. However, the present invention is not limited to this, and only the coordinate value of the place is held as the place information of the living and living list. Also good. Even in this case, the living and living list information corresponding to the position information can be specified by comparing the position information and the coordinate value of the place.

The present invention can be used for various music playback devices that play back a large number of music stored in a storage medium, such as a mini component, a portable audio player, a car audio, a karaoke device, and a mobile phone.
