  In the above configuration, the control unit 22 is an example of a display control unit and a change unit in the present invention, and the touch display 25 is an example of a display unit and an acquisition unit in the present invention.

[Playback control]
Next, playback control by the content playback apparatus 20 will be described. The music reproduction control by the content reproduction apparatus 20 is mainly performed by the user operating the touch display 25.

(Basic display)
FIG. 3A shows a basic display example of the main display 24, and FIG. 3B shows a basic display example of the touch display 25. In the song information display mode, as shown in FIG. 3A, the main display 24 displays information relating to the currently played song. Specifically, album artwork 31 including the song being played is displayed, and song information 32 regarding the song being played is further displayed. As the song information 32, a song name, an artist name, and an album name are displayed.

  On the other hand, as shown in FIG. 3B, the touch display 25 displays three areas, a timeline area 30, a recommendation area 40, and a stock area 50. The timeline area 30 and the recommendation area 40 are arranged side by side so as to contact each other. On the other hand, the stock area 50 is arranged below them so as to contact both the timeline area 30 and the recommendation area 40.

  The timeline area 30 displays a list of songs to be played (hereinafter also referred to as “playback list”). Specifically, in the timeline area area 30, the currently played song, the song to be played back, and the already played song are displayed in time series. In FIG. 3B, the lower side of the timeline area 30 corresponds to the past, and the upper side corresponds to the future. Conversely, the lower side of the timeline area 30 may correspond to the future, and the upper side may correspond to the past. In the timeline area 30, an artwork 31 and song information 32 of each song are displayed. The artwork 31 and the song information 32 are paired for each song, and move together from the top of the timeline area 30 to the bottom. In addition, on the artwork 31 of the song being played, a playing mark 31x indicating that the song is being played is superimposed and displayed. The position of the song being played in the timeline area 30 is fixed near the lower end of the timeline area 30. In the timeline area 30, a song positioned above the currently playing song with the playing mark 31 x is a song to be played back, and a song located below the currently playing song has already been played. It is a song.

  In the example of FIG. 3B, song A is currently being played back, and thereafter song B, song C, and song D are scheduled to be played in order. When the reproduction of the song ends, the artwork 31 and song information 32 of the song move downward and disappear from the timeline area 30. At the same time, the artwork 31 and the song information 32 of the next song move to the vicinity of the lower end of the timeline area 30, the song is played back, and a playing mark 31x is given to the artwork 31 of the song. . Thereafter, the artwork 31 and the song information 32 of each song scheduled to be reproduced are shifted downward by one song. In this way, each time the reproduction of the music is completed, the artwork 31 and music information 32 of each music in the reproduction list move from the top to the bottom of the timeline area 30. In the example of FIG. 3B, the display of a part of the artwork 31 and the song information 32 of the song that has just been played back is visible, but instead, playback has ended just before. The music artwork 31 and the music information 32 may be displayed so as to be visible. Conversely, the music artwork 31 and the music information 32 of the music that has just been played back may be completely invisible.

  In the recommendation area 40, songs recommended (recommended) for the user (hereinafter referred to as “recommended songs”) are displayed. Specifically, as shown in FIG. 3B, the recommended song object 41 is displayed in the recommendation area 40. The object 41 appears from above the recommendation area 40 and moves downward. In other words, the object 41 is dynamically displayed so as to drop from the recommendation area 40. In the area 42 above the recommendation area 40, the object 41 is displayed so as to drop instantaneously. That is, the object 41 is displayed in the area 42 so as to fall earlier than the other areas. Further, instead of displaying so as to drop instantaneously, the object 41 may be displayed so as to fall relatively faster in the area 42 than in other areas. Thereby, a visual impression that the object 41 has fallen from the top can be given to the user. The object 41 displayed in the recommendation area 40 flows downward as time passes and disappears below the recommendation area 40. By repeating this, the object 41 in the recommendation area 40 is updated. Although details will be described later, the user can add the object 41 of the recommended song to be reproduced to the reproduction list by moving the object 41 to the timeline area 30.

  The stock area 50 is an area for temporarily stocking the recommended song object 41 displayed in the recommendation area 40. The user can temporarily move to the stock area 50 songs that may not be heard immediately but may be heard later, or songs that are of interest to the user. When the user moves the object 41 to the stock area 50, the object 41 is displayed in the stock area 50. A plurality of objects 41 can be stocked in the stock area 50. The user can also save a plurality of objects 41 in the stock area 50 by dragging and dropping them together.

(Resize area)
Next, the size change of each area will be described. In the present embodiment, it is assumed that the user can arbitrarily change the sizes of the timeline area 30, the recommendation area 40, and the stock area 50 within the display area of the touch display 25. That is, the user can enlarge and reduce each area.

  Now, as shown in FIG. 3B, a state in which the timeline area 30 and the recommendation area 40 are approximately the same size is defined as a standard state. The user can enlarge the recommendation area 40 by performing a pinch-out operation in the recommendation area 40. “Pinch-out operation” refers to an operation of moving two fingers in contact with the touch display 25 so as to spread them. Instead, the user can reduce the timeline area 30 by performing a pinch-in operation in the timeline area 30, and as a result, can enlarge the recommendation area 40. “Pinch-in operation” refers to an operation of moving two fingers brought into contact with the touch display 25 closer to each other. FIG. 4A shows a state in which the recommendation area 40 is enlarged by performing a pinch-out operation in the recommendation area 40. When the recommendation area 40 is enlarged, the timeline area 30 is reduced accordingly, but the size of the stock area 50 is not changed. Further, instead of the pinch-out operation and the pinch-in operation, the user performs a drag operation in the left-right direction based on the boundary line between the timeline area 30 and the recommendation area 40, so that the timeline area 30 and the recommendation area 40 are changed. Each may be enlarged or reduced.

  When the recommendation area 40 is enlarged, the number of objects 41 displayed in the recommendation area 40 basically increases. However, instead of increasing the number of objects 41, the size of the object 41 displayed in accordance with the enlargement of the recommendation area 40 may be increased. Further, the number of objects 41 may be slightly increased and the size of each object 41 may be slightly increased. When the number of displayed objects 41 is increased, the speed at which the objects 41 flow from top to bottom may be slowed so that the user can easily see each object 41.

  When the timeline area 30 is reduced as the recommendation area 40 is enlarged, the artwork 31 and the music information 32 are basically reduced and displayed in the timeline area 30. However, depending on the size of the timeline area 30 after reduction, the number of artworks 31 and music information 32 to be displayed may be reduced, and the music information 32 may be omitted as shown in FIG. Only the work 31 may be displayed.

  On the other hand, the user can expand the timeline area 30 by performing a pinch-out operation in the timeline area 30. Instead, the user can also reduce the recommendation area 40 by performing a pinch-in operation in the recommendation area 40, and as a result, the timeline area 30 can be enlarged. FIG. 4B shows a state in which the timeline area 30 is enlarged by performing a pinch-in operation within the recommendation area 40. When the timeline area 30 is enlarged, the recommendation area 40 is reduced accordingly, but the size of the stock area 50 is not changed.

  When the timeline area 30 is enlarged, basically the artwork 31 and song information 32 displayed in the timeline area 30 are enlarged. At this time, the number of artworks 31 and song information 32 displayed may be reduced. By enlarging the artwork 31 and the song information 32, the user can easily see the image of the artwork 31 and the contents of the song information 32. Depending on the size of the enlarged timeline area 30, the information displayed as the song information 32 may be increased. For example, in the standard state, the song name, artist name, and album name are displayed as the song information 32. However, in the state where the timeline area 30 is enlarged, the song information 32 includes the genre, Release date, songwriter, composer, etc. may be displayed. In the example of FIG. 4B, the genre and release date are added to the song information 32 with the expansion of the timeline area 30.

  When the recommendation area 40 is reduced as the timeline area 30 is enlarged, the object 41 is basically reduced and displayed in the recommendation area 40. However, the number of objects 41 to be displayed may be reduced depending on the size of the timeline area 30 after reduction.

  Further, the user can enlarge or reduce the stock area 50 by moving the upper end of the stock area 50 up and down. FIG. 5 shows a state in which the stock area 50 is enlarged by moving the upper end of the stock area 50 upward. When the stock area 50 is enlarged, the corresponding area is displayed on the recommendation area 40 and the timeline area 30, but the display in the recommendation area 40 and the timeline area 30 does not change.

  When the stock area 50 is enlarged, the number of objects 41 displayed in the stock area 50 basically increases. Therefore, when the user stocks a large number of objects 41 in the stock area 50, the user can make the objects 41 in stock easier to see by enlarging the stock area 50. Depending on the size of the enlarged stock area 50 and the number of objects 41, the size of each object 41 may be enlarged.

(Object type)
Next, the types of objects displayed in the recommendation area 40 will be described. FIG. 6 shows display examples of various objects. In the recommendation area 40, a recommended song object (hereinafter also referred to as “recommended song object”) 41a for the user is basically displayed. However, in addition to the recommended song object 41a, a playlist object (hereinafter also referred to as “playlist object”) 41b and an acoustic control object (hereinafter referred to as “acoustic control object”) as shown in FIG. ) 41c is also displayed. In the present specification, when the type of the object is not specified, it is simply referred to as “object 41”.

  The playlist object 41b is a playlist object composed of a plurality of songs. In FIG. 6, a playlist object 41b composed of four songs E to H includes a four-divided area indicating the songs E to H on the display. The playlist object 41b composed of two songs P to Q includes a two-divided area indicating the songs P to Q on the display. By selecting the playlist object 41b, the user can add the playlist itself to the reproduction list in the timeline area 30.

  The acoustic control object 41c is an object indicating acoustic control applied to the music to be played. In the example of FIG. 6, the acoustic control object 41c is an object for applying acoustic control that reproduces a sound field in a live house. The user can apply acoustic control to a specific music piece by operating the acoustic control object 41c. The acoustic control object 41c will be described in detail later.

  In addition, although each object 41 flows from top to bottom in the recommendation area 40, the flow speed may vary depending on the type of the object 41. For example, the speed of the acoustic control object 41c may be slower than the recommended song object 41a and the playlist object 41b, and the speed of the acoustic control object 41c may be faster than the recommended song object 41a and the playlist object 41b. .

(Preview operation)
Next, the preview operation will be described. Although the recommended music object 41a is displayed in the recommendation area 40, the user can preview the recommended music temporarily by touching the recommended music object 41a. FIG. 7A shows a display example of the main display 24 during the preview operation, and FIG. 7B shows a display example of the touch display 25 during the preview operation.

  As shown in FIG. 7B, when the user touches the object 41c of the song M in the recommendation area 40, the song M is temporarily played while the user touches the object 41c (hereinafter referred to as “preview playback”). Also called.). During preview reproduction, as shown in FIG. 7A, the artwork 31 and song information 32 of the song M to be previewed are temporarily displayed on the main display 24. During the preview operation, the recommended song object 41a touched by the user stays at the same position in the recommendation area 40, but the other objects 41 flow downward as usual.

  Next, a method for reproducing a song by preview reproduction will be described in detail. Preview playback can be performed by any of the following first to third preview playback methods. Now, it is assumed that another song (assumed to be “Song X”) was played before the user performed the preview operation, that is, before touching the recommended song object 41a of the song M. In the first preview reproduction method, the reproduction of the music X is temporarily stopped when the user touches the recommended music object 41a of the music M, and a part of the music M is reproduced. When the user releases the touch on the recommended music object 41a of the music M, the music M is finished playing and the original music X is resumed. In this case, the reproduction of the original song X is resumed from the reproduction position when the user touches the recommended song object 41a of the song M. Note that switching between the music X and the music M may be performed by crossfading.

  In the second preview playback method, the playback of the original song X is continued without stopping during preview playback as described above, and the sound played back from the speaker 26 is muted (the playback sound is set to zero). Specifically, when the user touches the recommended song object 41a of the song M, the playback volume of the song X is temporarily muted and the song M is played back. Even during the reproduction of the music piece M, the reproduction sound of the original music X proceeds while the reproduction sound is not output. Then, when the user releases the touch of the recommended music object 41a of the music M, the music M is finished playing, the original music X is unmuted, and the playback volume is returned to the original volume.

  In the third preview reproduction method, reproduction of the music piece M is performed only with the specific speaker 26, preferably the speaker closest to the user who performed the preview operation, and the reproduction of the original music piece X is continued from the other speakers 26. For example, it is assumed that left and right speakers 26 are provided at the front and rear seats of the vehicle 1, respectively. Here, when the user sitting in the passenger seat performs a preview operation, the song M is reproduced only from the left front speaker 26 closest to the passenger seat, and the original song X is continuously reproduced from the other three speakers. The In this method, only the user who has performed the preview operation can try and listen to the preview reproduction of the song M, and the preview reproduction does not prevent other passengers from continuing to listen to the original song X.

  As another example of the preview operation, instead of continuing to touch the recommended song object 41a, as shown in FIG. 8B, the recommended song object 41a is moved upward with a finger and thrown out of the recommendation area 40. It may be. As shown in FIG. 1, since the main display 24 is usually arranged above the touch display 25 in the vehicle interior, this operation is an image operation in which the recommended song object 41 a is thrown into the main display 24. .

  When the user performs this operation, the recommended music object 41a of the music M once moves out of the recommendation area 40 and disappears. The music M is temporarily previewed and reproduced, and the artwork and music information of the music M are displayed on the main display 24. In the case of this preview operation, preview playback of the recommended song M and display of artwork and song information may be automatically terminated after a predetermined time has elapsed, or a separate operation button for preview playback is provided for the user. The preview reproduction may be terminated at any timing. When the preview reproduction ends, the recommended music object 41a of the music M is displayed again at the original position in the recommendation area 40. This allows the user to select this song M after preview playback.

(Select object)
Next, a method for selecting the object 41 flowing through the recommendation area 40 will be described. When the recommended song object 41a and the playlist object 41b flowing through the recommendation area 40 include a favorite one, the user moves (drags and drops) the object 41 to the timeline area 30 to make it into the playlist. Can be added. The selection of the acoustic control object 41c will be described later.

  FIG. 9 shows a method for selecting the object 41. As shown in FIG. 9A, when the user moves the object 41a of the recommended song M from the recommendation area 40 to the timeline area 30, the recommended song M is moved to the timeline area 30 as shown in FIG. Is added to the playlist displayed in. Specifically, the recommended music M is inserted into the playback position corresponding to the dropped position in the timeline area 30. In the example of FIG. 9A, since the user dropped the object 41a of the recommended song M between the albums B and C in the timeline area 30, the recommended song M is the album B as shown in FIG. Are inserted between the music B corresponding to the album C and the music C corresponding to the album C. Alternatively, when the user moves the object 41 to the timeline area 30, the recommended song may be added to the end of the current playlist.

  When the drop position of the object 41a by the user overlaps with the album position in the timeline area 30, the recommended song may be inserted before the album or after the album. Also good.

  In addition, the user can add the playlist object 41b to the playlist by dragging and dropping it in the timeline area 30 in the same manner as the recommended song object 41a. The playlist object 41b is also inserted at the playback position corresponding to the dropped position in the timeline area 30. As described above, the user can add a recommended song or a playlist to the reproduction list by a simple operation of dragging and dropping the recommended song object 41a and the playlist object 41b.

(Delete object)
Next, a method for deleting the object 41 flowing through the recommendation area 40 will be described. The user can delete the object 41 flowing through the recommendation area 40 by swiping out (sweeping out) the object 41 that is not of interest. This operation is similarly applied not only to the recommended song object 41a but also to the playlist object 41b and the acoustic control object 41c described above.

  FIG. 10 shows a method for deleting the object 41. In the example of FIG. 10, the user swipes the objects 41 of the recommended music M and L flowing in the recommendation area 40 and moves them out of the recommendation area 40. As a result, the objects 41 of the recommended songs M and L are deleted from the recommendation area 40. In the recommendation area 40, many objects 41 flow downward from above. If the user does not show interest and does not perform any operation, the object 41 disappears below the recommendation area 40, but the user actively deletes the object 41 that is not interested in other spaces. The object 41 can be displayed. By providing such a deletion operation, a user can recommend a large number of songs and sound control.

(Sound control)
Next, the sound control of the reproduced music by the sound control object will be described. As described above, the object 41 flowing through the recommendation area 40 includes the acoustic control object 41c. The acoustic control object 41c indicates acoustic control applied to the reproduced music. Here, “acoustic control” includes sound field control for controlling the sound field of the reproduced sound, and reproduction control for controlling the characteristics and the reproduction method of the reproduced sound itself. The sound field control is for controlling the characteristics of the reproduced sound in accordance with the characteristics of the sound field for reproducing the music, such as a live house, a concert hall, a church, and karaoke. “Playback control” controls the characteristics of the playback sound and the playback method according to user settings such as bass boost, loudness, equalizer settings by the user, playback speed, and playback volume change. Since the acoustic control object 41c can be basically applied to any music piece, the speed of flowing in the recommendation area 40 may be reduced. By making the flow speed of the acoustic control object 41c slower than the recommended song object 41a and the playlist object 41b, the user can easily apply the acoustic control to many songs.

  Specifically, the user can apply sound field control to the reproduced music by dragging and dropping the acoustic control object 41 c flowing in the recommendation area 40 into the timeline area 30. FIG. 11 shows an example of sound field control. Now, it is assumed that the acoustic control object 41c of the live house flows in the recommendation area 40 as shown in FIG. The user drags the sound control object 41c into the timeline area 30 and drops it on the artwork 31 of the album A corresponding to the song A currently being reproduced. Then, the sound field control of the live house is applied to the music A currently being reproduced, and the music A is reproduced from the speaker 26 in the live house mode. In this way, by dragging and dropping the acoustic control object 41c to the position of a predetermined reproduction music piece in the timeline area 30, the sound field control can be easily applied to the reproduction music piece. Note that the application target of the acoustic control object 41c is not limited to the music being reproduced. The sound control object 41c can also be applied by dragging and dropping it on the artwork 31 of the song in the reproduction list in the timeline area 30, that is, the song to be reproduced in the future.

  As shown in FIG. 11A, when the sound field control is applied, a mode display 24a indicating that the song A is being played in the live house mode is added to the main display 24, and the artwork 31 and song information 32 are further added. The background 24b is changed to a color, pattern, image, or the like corresponding to the sound field control of the live house. Thereby, the user can recognize that the acoustic control of the live house is applied to the currently reproduced music by looking at the display on the main display 24.

  In the above example, the user drags and drops the acoustic control object 41 c onto the artwork 31 of the specific song in the timeline area 30, but the user does not use the specific artwork 31 in the timeline area 30. When the sound control object 41c is dragged and dropped into the space, the sound control may be applied to all the songs in the current play list.

  Moreover, you may apply the some acoustic control object 41c to one music. For example, a sound field control object for reproducing a specific sound field and a reproduction control object for changing the reproduction speed may be applied to the same reproduction music.

  Further, preview reproduction may be performed using the acoustic control object 41c. Specifically, while the user touches the acoustic control object 41c, reproduction is performed by applying the acoustic control to the currently reproduced song. When the user releases the touch on the acoustic control object 41c, the application of the acoustic control is also canceled. In the example of FIG. 11B, while the user touches the acoustic control object of the live house in the recommendation area 40, the currently playing song A is played in the live house mode, and the display on the main display 24 is also shown. 11 (A) shows the live house mode. Thus, the user can perform trial playback and temporarily listen to the sound before the acoustic control object 41c is actually applied.

(Stock area)
Next, the stock area 50 will be described in detail. As described above, the stock area 50 is an area for temporarily storing the object 41 that the user is interested in, although it is not immediately applied to the playlist in the timeline area 30. The user can also drag and drop a plurality of objects 41 at the same time and save them in the stock area 50.

  FIG. 12 shows a basic operation using the stock area 50. When the user is interested in the object 41 a of the recommended song K in the recommendation area 40 and wants to listen to it later, the user drags and drops the object 41 a in the stock area 50 as indicated by an arrow 71. As a result, the object 41a of the song K moves into the stock area 50 and is saved. Thereafter, when the user wants to listen to the song M, the user drags and drops the song 41 object 41 a stored in the stock area 50 into the timeline area 30 as indicated by an arrow 72. In the example of FIG. 12, since the object 41a of the song K is dropped between the currently playing song A and the next song B, the song K is added next to the song A in the playlist. .

  Note that the object 41 that can be stored in the stock area 50 is not limited to the recommended song object 41a, and the playlist object 41b and the acoustic control object 41c can also be stored in the stock area 50. The user can temporarily store the playlist object 41b in the stock area 50, and drag and drop the playlist object 41b to the timeline area 30 for playback. In addition, the user temporarily stores the acoustic control object 41c in the stock area 50, and on the artwork 31 of the song in the timeline area 30 until the reproduction of the song to which the acoustic control is applied is started. If you drag and drop to, you can apply the sound control to the song and play it.

  In addition, the user can combine a plurality of objects 41 stored in the stock area 50. For example, the user can create a playlist by combining a plurality of recommended song objects 41 a temporarily stored in the stock area 50. FIG. 13 shows an example of an operation for creating a playlist in the stock area. As shown in FIG. 13A, recommended music objects 41 a of music P and music Q are stored in the stock area 50. When the user combines the recommended song object 41a of the song P and the recommended song object 41a of the song Q with a finger, a playlist object 41b including the song P and the song Q is generated as shown in FIG. .

  Similarly, the user can combine the recommended song object 41a and the playlist object 41b to generate a new playlist object 41. For example, by combining the recommended music object 41a of the music M and the playlist objects of the music P and Q, a new playlist object 41b including the music M, P, and Q is generated. In addition, the user can combine the playlist objects 41b to generate a new playlist object 41b. For example, by combining the playlist object 41b including the songs M and P and the playlist object 41b including the songs Q and R, a new playlist object 41b including the songs M, P, Q, and R is generated. The

  Further, the user can combine the recommended song object 41a and the acoustic control object 41c in the stock area 50 to generate the recommended song object 41a with acoustic control. For example, the recommended music object 41a of the music M in the live house mode is generated by combining the recommended music object 41a of the music M and the acoustic control object 41c of the live house.

  The user can delete unnecessary objects 41 stored in the stock area 50 by swiping unnecessary objects 41 and sweeping them out of the stock area 50. As a result, the user has stored in the stock area 50 in the hope of playing back later, but can delete the objects 41 that are no longer needed to organize the stock area 50. In this case, the user may sweep out the object 41 either in the left-right direction or below the stock area 50. It is also possible to delete a plurality of objects 41 by sweeping them together.

(Add related objects)
Regarding the object 41 displayed in the recommendation area 40, a related object may be added by a user operation. For example, as shown in FIG. 14, when an object 41a of a song M of a certain genre flows, if the user performs an operation of shaking (shaking) the object 41a, the song object 41a related to the song M is performed. May fall further. In the example of FIG. 14, when the user shakes the object 41 a of the music M, the music 41 and music objects 41 a related to the music M are added.

  In this case, the related music includes, for example, music of the same genre, music of the same artist, music of the same age, etc., and may be set in advance. In addition, the type of related music may be changed according to the direction of shaking the object 41a. For example, a song of the same genre may be added when shaken vertically, and a song of the same age may be added when shaken horizontally. The operation for adding the related object is not limited to the shake described above, and may be another operation such as a continuous tap operation and a simultaneous touch with two fingers.

(Object display control according to vehicle speed)
Next, object display control according to the vehicle speed will be described. The size and speed of the object 41 flowing through the recommendation area 40 can be changed according to the speed of the vehicle 1 on which the content reproduction apparatus 20 is mounted.

  First, the speed at which the object 41 flows in the recommendation area 40 can be changed according to the speed of the vehicle 1. Specifically, as shown in FIG. 15A, when the vehicle 1 is at a high speed, the falling speed of the object 41a is decreased, and when the vehicle 1 is at a low speed, the falling speed of the object 41 is increased. Accordingly, the user can easily see the object 41 according to the speed of the vehicle 1.

  Further, the size of the object 41 may be changed according to the speed of the vehicle 1. Specifically, as shown in FIG. 15B, the size of the object is increased when the vehicle 1 is at a high speed, and the size of the object is decreased when the vehicle 1 is at a low speed. Accordingly, the user can easily see the object 41 according to the speed of the vehicle 1. The control of the size of the object 41 may be executed in combination with the control of the drop speed of the object.

  Instead, the display interval of the object 41 in the recommendation area 40 may be changed according to the speed of the vehicle 1 without changing the size of the object 41. Specifically, the display interval of the object 41 is increased when the vehicle 1 is at a high speed, and the display interval of the object 41 is decreased when the vehicle 1 is at a low speed. This makes it easier for the user to see the object 41 even when the vehicle speed is high.

  Furthermore, the number of objects 41 that simultaneously flow in the recommendation area 40 may be changed according to the speed of the vehicle 1. Specifically, the number of objects 41 is reduced when the vehicle 1 is high speed, and the number of objects 41 is increased when the vehicle 1 is low speed. Accordingly, the user can easily see the object 41 according to the speed of the vehicle 1.

  When the vehicle 1 is stopped, the object 41 may basically be increased in speed or reduced in size, but when the vehicle 1 is temporarily stopped due to a signal or the like. Similarly to the traveling, the falling speed of the object 41 may be decreased or the size of the object 41 may be increased. Whether or not the vehicle is waiting for a signal can be determined based on, for example, turn signal information acquired from the vehicle 1, information on right and left turns on the route being guided, and the like.

  When the vehicle 1 is traveling, the speed of the object 41 is basically decreased or the size of the object 41 is increased. However, when the vehicle 1 is an automatic driving vehicle, the speed of the object 41 is in the automatic driving mode. You can speed up or reduce the size.

(Object display control according to the recommendation level)
Next, object display control according to the recommendation level will be described. The size and speed of the object 41a flowing through the recommendation area 40 can be changed according to the recommendation level of the content (song) corresponding to each object 41a.

  First, the falling speed of the object 41a can be changed according to the recommendation level of the content corresponding to the object 41a. Specifically, as shown in FIG. 16A, when the content recommendation level is high, the falling speed of the object 41a is decreased, and when the content recommendation level is low, the falling speed of the object 41a is increased. . As a result, the content object 41a having a higher recommendation level is more easily selected by the user.

  Further, the size of the object 41a may be changed according to the recommendation level of the content corresponding to the object 41a. Specifically, as shown in FIG. 16B, the size of the object 41a is increased when the recommended level of content is high, and the size of the object 41a is decreased when the recommended level of content is low. As a result, the content object 41a having a higher recommendation level is more easily selected by the user. The control of the size of the object 41a may be executed in combination with the control of the speed of the object.

  As described above, when the fall speed of the object 41a is changed in accordance with the recommended level of the content, the object 41a with the faster fall speed overtakes the object 41a with the slower fall within the recommendation area 40. In this case, it is possible that a plurality of objects 41a are temporarily overlapped. In this case, among the overlapping objects 41a, the object 41a with the higher recommendation degree may be displayed on the upper side. That is, the object 41a having the lower recommendation level falls through the back side of the object having the higher recommendation level.

  Furthermore, the operability of the object 41a on the touch display 25 may be changed according to the recommendation level of the content. Here, “operability” is the ease (weight) of movement of the object 41a by the user's operation. Specifically, as shown in FIG. 17, when the user moves the object 41 a displayed in the recommendation area 40 to the timeline area 30 or the stock area 50, the object 41 a corresponding to the highly recommended content is operated. The object 41a corresponding to the content having a low recommendation level is deteriorated (heavy) and made difficult to select. This makes it easier for the user to select content with a high recommendation level.

  Further, when the user sweeps out the object 41a displayed in the recommendation area 40 and deletes it, the object 41a corresponding to the highly recommended content has poor operability (heavy) and is difficult to delete. In addition, the object 41a corresponding to the content having a low recommendation level is improved (lighter) so that it can be easily deleted. This makes it difficult for the user to delete content with a high recommendation level. As a result, when the user tries to delete a plurality of objects 41a by sweeping them out of the recommendation area 40, the object 41a corresponding to the highly recommended content remains without being deleted. It is possible to prevent accidental deletion of highly recommended content. In addition, as shown in FIG. 17, it is preferable to display the object 41a with poor operability (heavy) so that the afterimage when moved is shown longer.

(Content recommendation)
Next, the recommended level of content will be described. The recommendation level is an index indicating the degree of recommendation of content to the user, is set for each content, and is stored in the storage unit 23 of the content playback device 20. In the present embodiment, music is reproduced as content, so the degree of recommendation is determined and stored for a large number of music. Note that the recommendation level information may be basically managed by a server, and may be downloaded to the content reproduction device 20 of each user's vehicle and used as necessary.

  The degree of recommendation for each song is determined based on a large amount of information. Typically, first, the recommendation degree is determined based on the popularity of each song in the world. For example, the basic recommendation degree of each song is determined based on the ranking in a domestic or overseas music chart, the number of times of music selection at a karaoke shop, and the like. Furthermore, the recommendation level is corrected for each user. Specifically, the basic recommendation level is weighted according to the attribute information such as the user's age, sex, etc., the user's preference for music (such as the favorite music genre), and the user's past music selection history. Then, the recommended degree of each song is corrected for each user. In this way, the degree of recommendation for a large number of songs is stored in the storage unit 23 for each user. Note that the above method is merely an example, and the degree of recommendation can be determined by various known methods for recommending content to the user.

  Next, a method for recommending content will be described. When recommending the content, the control unit 22 refers to the recommendation level of each song stored in the storage unit 23 and extracts a song having a recommendation level equal to or higher than a predetermined value as a recommended song. And the control part 22 selects those recommended music in a predetermined order or at random, and displays them on the recommendation area 40 as the recommended music object 41a. Basically, music with a higher recommendation level is recommended more frequently, but it is preferable to provide a certain time interval so that the same music is not recommended continuously. In this way, a recommended song is recommended based on the degree of recommendation. Note that the above method is merely an example of a method for recommending music based on the recommended degree, and other known methods may be adopted.

  Next, a method for changing the recommendation level based on a user operation on the object 41 will be described. The recommendation level of each song is determined as described above, and the object 41a corresponding to the song is displayed in the recommendation area 40. Here, the operation performed by the user on the object 41a reflects the user's preference for the corresponding recommended song. Therefore, in the present embodiment, the recommended degree of each song is corrected as follows according to the operation performed by the user on the object 41a displayed in the recommendation area 40.

  First, when the user moves the object 41a displayed in the recommendation area 40 to the timeline area 30 and adds it to the playlist, the user is interested in the song and guesses that the song is the user's favorite song. be able to. Therefore, the control part 22 increases the recommendation degree of the music. On the other hand, when the user deletes the object 41a displayed in the recommendation area 40, the user can be inferred that he / she has little interest in the song and is not so liking. Therefore, the control part 22 reduces the recommendation degree of the music.

  If the user does not perform any operation on the object 41 displayed in the recommendation area 40 and disappears from the recommendation area 40 with the passage of time, it cannot be determined whether the preference for the song is good or bad, so the recommendation level is not changed. . However, if the user does not perform any operation on the object 41 displayed in the recommendation area 40 and disappears from the recommendation area 40 over time, it is determined that the preference for the song is bad. May be.

  If the user previews and plays an object 41a and adds it to the playlist, the user can be inferred that he / she is highly interested in the song. Therefore, the control part 22 increases the recommendation degree of the music. In this case, the degree of increasing the recommendation degree may be larger than when the music is added to the playlist without preview playback. On the other hand, when the user deletes the object 41a after preview playback, the user can be inferred that the user is not interested in the object 41a. Therefore, the control part 22 reduces the recommendation degree of the music. In this case, the degree of reduction of the recommendation degree may be increased as compared with the case where the music is deleted without preview playback.

  Furthermore, the user may determine a predetermined operation for expressing his / her preference in advance for the object 41 displayed in the recommendation area 41, and increase or decrease the recommendation level depending on whether or not the operation has been performed. good. For example, when it is determined that an operation of tracing the periphery of the object 41a with a finger or an operation of enlarging the object 41a by a pinch-out operation is an operation indicating that the object 41 is a favorite object, such an operation is performed. The recommendation degree of the music corresponding to the performed object 41a is increased. On the other hand, when it is determined that the operation of reducing the object 41 by the pinch-in operation is an operation indicating that the object is not a favorite object, the recommendation of the music corresponding to the object 41a on which such an operation has been performed is recommended. Decrease the degree. The operation indicating that the object is a favorite object and the operation indicating that the object is not a favorite object may be performed on the plurality of objects 41a at the same time.

  The music object 41 whose recommendation level has been increased as described above has a high display frequency or a large display size when it is displayed in the recommendation area 40 after the next time. On the other hand, the music object 41 with the reduced recommendation level is displayed less frequently or displayed smaller when it is displayed in the recommendation area 40 after the next time.

  FIG. 18 is a flowchart of the recommendation level changing process. This process is executed by the control unit 22 of the content reproduction apparatus 20. First, the control unit 22 displays the object 41a corresponding to the recommended song in the recommendation area 40 (step S11). Next, the control unit 22 determines whether or not the user has performed a recommendation degree increasing operation on the displayed object 41a (step S12). Here, the “recommendation increasing operation” is a predetermined operation such as an operation of adding the object 41 to the timeline area 30 or an enlargement of the object 41 as described above.

  When the recommendation degree increasing operation is not performed (step S12: No), the process proceeds to step S14. On the other hand, when the recommendation degree increasing operation is performed (step S12: Yes), the control unit 22 increases the recommendation degree of the music corresponding to the object 41 (step S13), and proceeds to step S14.

  In step S <b> 14, the control unit 22 determines whether or not the user has performed a recommendation level reduction operation on the displayed object 41. Here, the “recommendation degree reduction operation” is a predetermined operation such as an operation for deleting the object 41 from the recommendation area 40 or a reduction of the object 41 as described above.

  If the recommendation degree decreasing operation has not been performed (step S14: No), the process ends. On the other hand, when the recommendation level reduction operation is performed (step S14: Yes), the control unit 22 decreases the recommendation level of the music corresponding to the object 41a (step S15), and ends the process. In this way, by changing the recommendation level of each song according to the user's operation on the displayed object 41a, it is possible to always recommend content that matches the user's preference.

[Modification]
Next, various modifications of the above embodiment will be described. Note that the modifications described below can be applied in any combination.
(Modification 1)
In the above embodiment, each object 41 flows from the top to the bottom in the recommendation area 40 and disappears from the lower end of the recommendation area 40. However, the display method of the object 41 is not limited to this. For example, as shown in FIG. 19, a saucer 45 is displayed below the recommendation area 40, and after each object 41 is caught by the saucer 45, it is displayed so that it gradually becomes smaller on the saucer 45 and eventually disappears. May be.

  When displaying the tray 45, the object 41 caught by the tray 45 may be automatically moved to the timeline area 30 after a predetermined time. In this case, the user can save time and effort to move each object 41 to the timeline area 30. Instead, the user needs to move the object 41 that he / she does not like out of the recommendation area 40 and delete it.

  Note that the moving direction of the object 41 in the recommendation area 40 is not limited to top to bottom, and may be displayed so as to move from bottom to top. At this time, the object 41 may be displayed so as to move in a floating shape in the image of a balloon or a soap bubble. In this case, the object 41 may be displayed so as to disappear upward from the upper end, or the object 41 is deleted by adding an effect that images that a balloon or a soap bubble breaks when the object 41 reaches the vicinity of the upper end. May be. Alternatively, when the object 41 reaches the vicinity of the upper end, the balloons and the soap bubbles may be gradually reduced so as to be deflated and then disappear.

(Modification 2)
In the above embodiment, the content playback device 20 is mounted on a right-hand drive vehicle, but can also be mounted on a left-hand drive vehicle. In that case, as shown in FIG. 20, the timeline area 30 and the recommendation area 40 displayed on the touch display 25 may be interchanged.

(Modification 3)
In the above embodiment, the user's touch operation on the touch display 25 is detected. Instead, a non-contact operation such as an air gesture by the user may be detected using a separation sensor or the like.
