  The external server 5 has a music database 51 in which a large number of music data is stored. The in-vehicle device 1 can acquire music data from the music database 51 and the acquired music data can be reproduced by the AV unit 13.

  With the above-described configuration, the in-vehicle device 1 has a music feature for music data stored in a predetermined storage area such as the music database 51 of the external server 5, the music memory 22 of the mobile terminal 2, and the memory 11 of the in-vehicle device 1. Generate a song list by quantity. For each music list, the recommendation level (recommended level for the user) of each music is calculated based on the user's operation history, the measurement result of the bracelet 3, the detection result of the vehicle control device 4, and the like. The artwork of some music is presented to the user (displayed on the touch panel TP, see FIG. 3 etc.).

  Next, the functional configuration of the in-vehicle device 1 will be described with reference to FIG. The in-vehicle device 1 includes a display unit 110, an operation unit 120, a music list generation unit 130, a recommendation level determination unit 140, a display control unit 150, and a reproduction control unit 160 as main functional configurations. Among these, the display unit 110 and the operation unit 120 are realized by the touch panel TP. The other units are mainly realized by the AV unit 13 and the control unit 19.

  For example, in the case of the artwork mode, the display unit 110 displays the artworks of a plurality of music pieces in a tiled manner on the touch panel TP (predetermined display area). FIG. 3 is a diagram illustrating a display example of the artwork screen D1 displayed in the artwork mode. In the drawing, tiles (rectangular areas) described as “(AW-***)” indicate artworks (disc jackets, etc.) of each music piece. In addition, tiles described as “GENRE REFRESH”, “HIT CHART REFRESH”, and “EPM REFRESH” correspond to the music feature quantities “genre”, “hit chart”, and “EPM”, respectively, and the artwork screen D1. Are arranged one by one at an arbitrary position. Hereinafter, these tiles indicating the music feature quantities are referred to as “feature quantity tiles”. Since the “feature amount tile” is displayed according to the music feature amount set by the user, the display number is arbitrary. Further, it may be hidden by a refresh tile operation described later.

  A tile described as “ALL REFRESH” is a refresh tile arranged at an arbitrary position on the artwork screen D1. The refresh tile is always displayed only in one place in the artwork screen D1 regardless of the set music feature amount. Further, the tile displayed largely in the center of the touch panel TP indicates the artwork of the music being played. On the other hand, in the status mode, the display unit 110 displays a status screen D2 (see FIG. 12) showing detailed information of the music being played. Details of the screens D1 and D2 will be described later.

  The operation unit 120 performs operations on the screens D1 and D2 displayed on the touch panel TP. For example, in the artwork mode, a replacement of artwork or a reproduction start instruction is performed. In the status mode, playback operation and various settings are performed.

  The music list generation unit 130 generates a music list in which music stored in a predetermined storage area such as the memory 11, the music memory 22, and the music database 51 is classified according to the music feature amount. Here, what is adopted as the music feature amount can be set on the status screen D2. In this embodiment, it is assumed that three types of “genre”, “hit chart”, and “EPM” are set as music feature amounts. Note that the music feature amount refers to information serving as a reference when classifying music. Therefore, in addition to these three types, “age”, “artist”, “BPM (Beats Per Minute)”, “Key”, and the like can be set.

  FIG. 2B is a diagram showing an example of the created music list. Here, the “genre” song list is a list of songs belonging to the genre (jazz, rock, pops, etc.) set on the status screen D2. The song list of the “hit chart” is a list of songs belonging to the top of the ranking determined based on the sales and requests of the songs. The music ranking is assumed to be stored in the music database 51 of the external server 5. The “EPM” song list is a list of songs to which EPM values are added as metadata. The EPM value is a numerical value of the active feeling of music, and is expressed, for example, in 100 levels of “1 to 100”.

  The recommendation level determination unit 140 determines the recommendation level of each song based on one or more elements of “user preference”, “user biometric information”, and “environment information” for each song list. Which of these elements is adopted is set for each music list on the status screen D2. The weighting of each element is also set for each music list on the status screen D2. Therefore, even if the music is the same, the degree of recommendation calculated by the classified music list is different. In the music list shown in FIG. 2B, the identification information (music ID) of each music is listed in descending order of recommendation. The recommendation level is expressed in, for example, 100 levels of “1 to 100” (see parentheses after each music ID).

  Here, the “user preference” is an operation history of each piece of music data in the in-vehicle device 1 and / or the mobile terminal 2 (the number of times each piece of music data is played, the total number of times played, the number of searches, the number of trials, whether or not purchased, etc.). Judgment based on. In other words, the degree of recommendation of the music that is determined to be user's preference from the operation history is high. The “user's biological information” is determined based on the measurement result of the bracelet 3 (the body temperature sensor 32 and / or the heart rate sensor 33). Note that what is adopted as the biological information is set on the status screen D2. However, the “user's biometric information” is reflected only when “EPM” is adopted as the music feature amount on the status screen D2. For example, when it is determined from the measurement result of the bracelet 3 that the user is excited, the recommendation degree of the music with a low active feeling (low EPM value) is high.

  Further, the “environment information” is determined based on the traveling position of the vehicle and / or the traveling state of the vehicle. Note that what is adopted as the environment information is set on the status screen D2. “Vehicle travel position” is registered in the region type (sea, mountain, city area, etc.), road type (highway, national road, prefectural road, municipal road, etc.), nearest tourist destination, and navigation unit 12. The destination and mark point. The “vehicle traveling position” can be detected by acquiring current position information from the navigation unit 12. In addition, the “vehicle running state” refers to a running speed, a degree of vehicle shaking (side slip, wobbling, deviation from diagonal lines, etc.), a brake frequency, and the like. The “vehicle running state” can be detected by acquiring measurement results of the acceleration sensor 42 and the vibration sensor 43 from the vehicle control device 4. When the recommendation level is determined based on “environmental information”, for example, if the current travel position is near “the sea”, the recommendation level of the music related to the sea (a music to which keywords related to the sea are added as metadata) When the vehicle becomes high and the wobbling of the vehicle becomes large, the recommendation degree of the music with a high BPM increases to prevent falling asleep.

  When displaying the artwork screen D1, the display control unit 150 preferentially displays the artwork related to the highly recommended music in each music list. For example, when the music list shown in FIG. 2B is generated, as shown in FIG. 3, the number of artworks that can be displayed on the artwork screen D1 in order from the music with the highest recommendation degree (in the example of FIG. 3). , 16) are selected and displayed. Note that “***” in the notation of each artwork (AW-***) indicates the music feature amount (G: genre, H: hit chart, E: EPM) of the corresponding music and the rank ( 2 digits).

  Further, the display control unit 150 arranges artworks of music pieces belonging to the same music list in the proximity on the artwork screen D1, and replaces the artwork to be displayed with the passage of time. In the present embodiment, the artwork is replaced every predetermined time t2 (periodically). In addition to this, when at least one of “user's biological information” and “environment information” changes, the artwork is replaced. Note that the artwork is replaced by giving priority to the artwork of a song with a low recommendation degree in each song list among the artworks displayed on the touch panel TP. For example, for an arbitrary music list, when five artworks with the first to fifth recommendation degrees are displayed, the artwork with the fifth recommendation degree is first replaced with the artwork with the sixth recommendation degree, and the next timing Then, display control such as replacing the artwork having the fourth recommendation level with the artwork having the seventh recommendation level is performed. It should be noted that, depending on the setting of the status screen D2, a predetermined number of artworks from the top of the recommendation level may not be replaced.

  In addition, when the operation control unit 120 performs a flick operation (operation having a first direction) toward the outside of the touch panel TP with an arbitrary artwork as a starting point (starting point), the display control unit 150 Replace the artwork in with other artwork that is not displayed. The “flick operation” refers to an operation of touching the screen so as to quickly pay off. Further, when the feature amount tile indicating the song feature amount of each song is touched by the operation unit 120, all the displayed artwork is displayed as the art of the song in the song list corresponding to the touched feature amount tile. Replace with work. Further, when the operation unit 120 touches a refresh tile arranged at only one place on the touch panel TP, all the displayed artwork is replaced.

  In addition, the display control unit 150 has the same alphabet in the first “*” of each artwork group (AW-***), which is a collection of artworks of music pieces belonging to the same music list. In the example of Fig. 3, the display positions of the symbols E02 to E04) in the touch panel TP are changed with the passage of time. In the present embodiment, the display position of each feature quantity artwork group (the display position of each artwork constituting the feature quantity artwork group) is gradually turned clockwise every predetermined time t1 (periodically). Rotate.

  When a flick operation toward the inside of the touch panel TP starting from an arbitrary artwork is performed on the artwork screen D1, the reproduction control unit 160 starts to reproduce the music corresponding to the arbitrary artwork. Also, after the music playback is completed, auto playback (automatic selection / auto playback of the next music) is performed. At this time, it is preferable to select the next song based on the song list to which each song belongs and the recommendation level. Note that the playback control unit 160 performs auto-playing after the display of the artwork screen D1 is started until a playback start operation is performed by the user.

  Next, the configuration of the artwork screen D1 will be described with reference to FIG. On the artwork screen D1, as shown by reference numeral E01, the artwork of the music being reproduced (in the example of the figure, the music of “AW-E04”) is displayed largely in the center of the touch panel TP (reproduced music display area) E01). In the example of the figure, the playback music display area E01 is four times as large as other artwork, but it may be set to a user's favorite size by setting. The size of the artwork other than the playback music display area E01 (artwork of a music not being played back) may be set. Note that the size of the artwork may be set as an absolute value such as mm or display pixel, or may be set as a relative value such as large, medium, or small.

  Further, as shown by reference symbols E02 to E04, artwork groups by feature amount are displayed in correspondence with the three types of music feature amounts “genre”, “hit chart”, and “EPM” (display region by feature amount). E02-E04). Also, each feature amount tile (“GENRE REFRESH”, “HIT CHART REFRESH”, “EPM REFRESH”) indicating the corresponding feature amount is arranged so as to be in contact with at least one artwork in each artwork group for each feature amount. To do. In the example shown in the figure, the feature amount tile has the same size as the surrounding artwork, but may be set to a user's favorite size by setting.

  Further, as indicated by reference numerals E02 to E04, the artwork belonging to the same artwork group by feature amount and the feature amount tile are displayed with the same decoration. In the present embodiment, as decoration, a frame of the same color is added for each music feature amount (in the drawing, the color of the frame is expressed by a difference in a filling pattern). Note that the music feature amount and the frame color are not 1: 1, but are determined by the selection order of the music feature amount. For example, when “genre”, “hit chart”, and “EPM” are selected as music feature quantities, the “genre” frame is red, the “hit chart” frame is blue, and the “EPM” frame is If the number is “Yellow” and “Hit Chart” and “EPM” are selected, the “Chart Chart” frame is red and the “EPM” frame is blue. The set color is changed according to the order. In addition, the display position of each artwork group for each feature amount on the touch panel TP is determined according to the set frame color. In the present embodiment, the arrangement order of each artwork group according to feature amount in an arbitrary rotation direction centered on the reproduced music display area E01 is determined according to the hue circle.

  Further, as indicated by reference numeral E05, a refresh tile is displayed only at one position at an arbitrary position on the touch panel TP (refresh tile display area E05). The refresh tile is decorated differently from the decoration added to each feature-based artwork group.

  Next, a change in the artwork screen D1 with time will be described with reference to FIG. FIG. 4 shows a display example of the artwork screen D1 after a fixed time (a time longer than the predetermined times t1 and t2) has elapsed from the state of FIG. However, the music being reproduced is assumed to be the same music.

  As shown in FIG. 4, the feature-specific display areas E02 to E04 are slightly moved in the clockwise direction around the reproduced music display area E01 as compared with the state of FIG. At this time, each feature amount tile also moves in the same manner as the corresponding artwork. Further, the refresh tile display area E05 also moves in the clockwise direction as other tiles move. In FIG. 4, the artwork to be displayed is also replaced. In this case, the artwork of music with a low recommendation level is preferentially replaced in each music list. For example, in the feature area display area E02 of “genre”, two artworks (“AW-G07” and “AW-G08”) are not displayed compared to the state of FIG. In addition, one artwork (“AW-H06”) is added in the feature area display area E03 of “hit chart”, and one artwork (“AW−” is displayed in the feature area display area E04 of “EPM”. E05 ") is added. In addition, in each feature amount display area E02 to E04, the artwork is rearranged together with the artwork. The rearrangement of the artwork is based on a predetermined algorithm such as random arrangement.

  Next, the flow of display control in the in-vehicle device 1 will be described with reference to the flowchart of FIG. Here, it is assumed that the user does not perform an artwork replacement operation. The in-vehicle device 1 (display control unit 150) determines whether or not a predetermined time t1 has elapsed since the previous rotation of the artwork group by feature amount (movement of the display position) (S01). If the predetermined time t1 has elapsed (S01: Yes), the display position of the artwork group by feature amount is rotated (S02). If the predetermined time t1 has not elapsed (S01: No), S02 is omitted.

  Thereafter, it is determined whether or not a predetermined time t2 has elapsed since the previous artwork replacement (S03). If the predetermined time t2 has not elapsed (S03: No), whether or not at least one of “user's biometric information” and “environment information” has changed (whether there has been a change in the order of recommendation of each music list). (S04), and if not changed (S04: No), the process returns to S01. In addition, when a predetermined time t2 has passed since the previous replacement of the artwork (S03: Yes), or when at least one of “user's biometric information” and “environment information” has changed (S04: Yes), the artwork Are replaced (S05), and the process returns to S01.

  Next, with reference to FIGS. 6 to 11, changes in the artwork screen D <b> 1 associated with user operations will be described. As shown in FIG. 6, a flick operation is performed from an arbitrary artwork (“AW-H04” in the example of the figure) toward the outside of the touch panel TP (for example, in the direction of reference numerals 61 to 63). Then, as shown in FIG. 7, instead of an arbitrary artwork, another artwork is displayed (in the example of FIG. 7, “AW-H06”). However, the replacement with another artwork is made on condition that it belongs to the same music list as the music corresponding to an arbitrary artwork.

  Further, as shown in FIG. 8, a flick operation is performed from an arbitrary artwork (“AW-H04” in the example in the figure) toward the inside of the touch panel TP (for example, in the directions of reference numerals 65 and 66). As shown in FIG. 9, an arbitrary artwork is displayed in the reproduction music display area E01, and reproduction of a music corresponding to the arbitrary artwork is started. In addition, in the area where the arbitrary artwork has been displayed, another artwork is displayed instead of the arbitrary artwork ("AW-H06" in the example in the figure). In this case as well, replacement with another artwork is conditional on belonging to the same music list as the music corresponding to the arbitrary artwork.

  As shown in FIG. 10, when an arbitrary feature amount tile (“GENRE REFRESH” in the example of the figure) is touched from the state of FIG. 3, all artwork displayed on the touch panel TP and The feature amount tiles other than the arbitrary feature amount tiles (in the example of the figure, “HIT CHART REFRESH”, “EPM REFRESH”) are replaced with the artwork of the song in the song list corresponding to the touched feature amount tile. In other words, in the example of the figure, all the displayed artwork is the artwork of the music belonging to the “genre” music list. In this case, the artwork is not replaced or rearranged in the display area E02 classified by feature amount “genre”. Further, the display position of the reproduced music (display of the reproduced music display area E01) and the refresh tile display area E05 does not change.

  As shown in FIG. 11, when the refresh tile (“ALL REFRESH”) is touched from the state shown in FIG. 3, all the artworks displayed on the touch panel TP are replaced. In this case, the display position of each feature amount tile does not change. Further, the display position of the reproduced music (display of the reproduced music display area E01) and the refresh tile display area E05 does not change. Further, the display positions of the feature-specific display areas E02 to E04 and the number of artworks constituting each feature-value artwork group do not change.

  Next, the configuration of the status screen D2 will be described with reference to FIG. The display switching from the artwork screen D1 to the status screen D2 (switching from the artwork mode to the status mode) is executed by touching the reproduction music display area E01 of the artwork screen D1 (not shown). As shown in the figure, the status screen D2 is generally designed based on “circle”, and can be distinguished at a glance from the artwork screen D1 based on “square”. The display switching from the status screen D2 to the artwork screen D1 is executed by touching a predetermined screen switching button (not shown) provided on the status screen D2 or a reproduction music display area E11 described later. .

  In the center of the status screen D2, a circular reproduction music display area E11 for displaying the artwork of the music being reproduced is arranged, and the periphery thereof is concentric with the reproduction music display area E11 and has a diameter larger than that of the reproduction music display area E11. A reproduction music information area E12, a reproduction music operation area E13, a recommendation level setting area E14, and a sound setting area E15 are arranged so as to divide a large circular area by a sector. The reproduction music information area E12 displays metadata and source sources (recording media such as the memory 11, the music memory 22, and the music database 51) of the music being reproduced. The playback song operation area E13 displays a GUI (Graphical user interface) related to playback song operations such as a play / pause button, fast forward / rewind button, and the like mounted on a general audio device.

  The recommendation level setting area E14 is an area for selecting and setting each condition for determining the recommendation level, and displays selection buttons and setting areas for the following items. In the recommendation level setting area E14, selection of music feature quantities (selection of feature quantity types such as “genre”, “hit chart”, “EPM”, “age”), and detailed settings thereof (designation of “genre”, “age”) Etc.), selection of parameters for determining the recommendation degree (for each music list, which element of “user preference”, “user biometric information” and “environment information” is adopted, and its weight Setting), selection of biological information (which of temperature sensor 32 and heart rate sensor 33 is adopted), selection of environmental information (which of “traveling position” and “traveling place” of the vehicle is employed), A source source is selected (which of the memory 11, music memory 22, and music database 51 is targeted). If the setting is changed in the recommendation level setting area E14, the recommendation level of each music list is affected, so the display of the artwork screen D1 is updated.

  In addition, the sound setting area E15 displays a GUI related to sound setting such as a setting area for performing equalizer setting and volume setting, and a spectrum analyzer (music waveform) display, which is mounted on general audio equipment.

  A link display area E16 is arranged at the lower right of the status screen D2. The link display area E <b> 16 indicates the link state between the in-vehicle device 1 and the bracelet 3 by ON / OFF of an image imitating the bracelet 3. When the in-vehicle device 1 and the bracelet 3 are in an unlinked state, the biometric information does not affect the recommendation level of the music list “EPM” even when the biometric information is selected in the recommendation level setting area E14.

  As described above, according to the present embodiment, on the artwork screen D1, artwork of one or more songs belonging to each song list classified by feature amount is displayed in a tiled manner on the touch panel TP and displayed. Since the target artwork is replaced with the passage of time, the music can be presented in a better-looking manner as compared with the conventional playlist that lists the music titles according to the reproduction order. Also, by replacing the artwork, it is possible to always present fresh music to the user. Also, by expanding the source of music, such as the external server 5, you can expect encounters with unexpected music that the user has never listened to.

  In addition, when the user does not perform any operation, the music selection operation is not required by auto-play, and thus the user during driving is not bothered. On the other hand, the music can be changed or stopped by user operation. As described above, according to the present embodiment, it is possible to realize a music presentation method that takes advantage of radio and eliminates disadvantages.

  Further, according to the present embodiment, on the artwork screen D1, the artwork is exchanged in order to exchange the arbitrary artwork with another artwork by a flick operation directed to the outside of the touch panel starting from the arbitrary artwork. Can be easily performed in one step. Further, since it is possible to replace a plurality of music pieces at once by touching the feature amount tile or the refresh tile, the operation is further facilitated. Further, since the music corresponding to the arbitrary artwork is started by a flick operation toward the inside of the touch panel starting from the arbitrary artwork, the reproduction operation can be easily performed in one step.

  Further, since the screen can be switched to the status screen D2 by touching the artwork (reproduced music display area E01) of the music being played displayed in the center of the artwork screen D1, a menu screen is displayed and desired. Compared with the conventional screen switching method for switching to this screen, detailed information can be confirmed and detailed settings can be performed with fewer steps.

  In addition, the following modifications can be employed. For example, the display control unit 150 of the above embodiment displays the artwork of all songs except the artwork of the song being played in the same size (see FIG. 3 etc.), but depending on the recommendation level of each song The display size of each artwork may be varied. That is, the artwork of a song with a high recommendation level may be displayed larger than the artwork of a song with a low recommendation level. According to this configuration, the user can grasp the degree of music recommendation at a glance.

  In the above embodiment, the color of the frame to be added to the artwork is varied as the decoration for each music feature. However, the frame pattern (pattern) is variable in place of the frame color or together with the frame color. You may do it. Further, instead of the frame, the background color of each artwork (tile) may be changed, or a predetermined mark may be added.

  As a modification, instead of setting the frame color for each music feature amount, an intermediate color between two types of music feature amounts may be set. For example, a reddish purple frame for an artwork corresponding to a song with a recommendation level of “1” for “genre” set in red and a recommendation level of “5” for “hit chart” set for blue May be added. Thereby, gradation can be formed in the whole artwork, and the appearance can be further improved. Further, since the user can infer two types of music feature amounts from the color of the frame, the music can be selected more intuitively.

  Further, in the above embodiment, the disc jacket of the music is illustrated as the artwork, but the present invention is not limited to this, and for example, an original image created for the music by the user may be used as the artwork. That is, “artwork of music” in the claims means an artwork associated with the music.

  In the above embodiment, when the predetermined time t1 has elapsed, the artwork group by feature amount is rotated, and when the predetermined time t2 has elapsed, or at least one of “user's biological information” and “environment information” Although the artwork is replaced when the value changes (see FIG. 5), rotation of the collection-based artwork group and the replacement of the artwork may be performed at the same timing. Further, the presence / absence and rotation direction of the artwork group by feature amount, the presence / absence of the artwork replacement, the replacement algorithm, and the predetermined times t1 and t2 may be variable by setting.

  Further, in the above embodiment, when an artwork is exchanged or a playback start instruction is given, “an operation on an arbitrary artwork” is an operation starting from an arbitrary artwork. You may prescribe | regulate as operation which makes a work an end point, or operation which makes an arbitrary artwork a waypoint. Further, among these operations, it may be possible to set on the status screen D2 which operation is used to change the artwork or instruct to start reproduction.

  In the above embodiment, the flick operation toward the outside of the touch panel TP is exemplified as the operation for replacing the artwork (operation having the first direction). It may be defined as one or more of a downward direction, a right direction, a left direction, a right diagonal direction, and a left diagonal direction. Moreover, you may prescribe | regulate as an inner side. Similarly, the flick operation toward the inner side of the touch panel TP has been exemplified as the operation for instructing the start of reproduction (operation having the second direction), but may be defined as one or more of the above options. . Further, in addition to the flick operation, the artwork may be replaced or the reproduction may be started by other operations with directionality such as a drag operation, pinch in (pinch close) / pinch out (pinch open), and the like.

  In the above embodiment, in the recommendation level setting area E14 of the status screen D2, a parameter for determining the recommendation level is set for each music list. However, as a parameter common to all music lists, You may set all at once.

  In the above embodiment, the biological information of the vehicle occupant (driver) is detected by the bracelet 3, but the biological information may be detected by another device (for example, a thermometer or a heart rate measuring device). The portable terminal 2 may be provided with a biological information detection function (body temperature sensor 32 and heart rate sensor 33).

  In the above embodiment, the artwork is displayed for the purpose of presenting the music to the user. However, the present invention can also be applied to the case of presenting content (video, still image, etc.) other than the music data. .

  In the above embodiment, the display unit 110 and the operation unit 120 are realized by the touch panel TP, but may be realized by individual hardware. In the above embodiment, the case where the present invention is applied to the in-vehicle device 1 is illustrated, but the present invention can also be applied to other electronic devices (display device, operation device).

  Moreover, it is possible to provide each component of the vehicle-mounted system SY shown above as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each component of the in-vehicle system SY and a recording medium on which the program is recorded are also included in the scope of rights of the present invention. Other modifications can be made as appropriate without departing from the scope of the present invention.
