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

  With the above-described configuration, the on-vehicle device 1 targets the 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 on-vehicle device 1. Generate a music list by volume. Then, for each music list, the recommendation degree (recommendation degree to 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, etc. The artworks of several songs are 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 on-vehicle apparatus 1 includes a display unit 110, an operation unit 120, a music list generation unit 130, a recommendation degree 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 components 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 artworks of a plurality of music pieces arranged in a tile on the touch panel TP (predetermined display area). FIG. 3 is a view showing a display example of the artwork screen D1 displayed in the artwork mode. In the same figure, the tile (rectangular area) described as "(AW-***)" indicates artwork (such as a disc jacket) of each music. The tiles described as "GENRE REFRESH", "HIT CHART REFRESH", and "EPM REFRESH" correspond to the music feature amounts "genre", "hit chart", and "EPM", respectively, and the artwork screen D1 It is arranged one by one at any position of. Hereinafter, a tile indicating each of the music feature amounts is referred to as a “feature amount tile”. Since the “feature amount tile” is displayed according to the music feature amount set by the user, the number of display is arbitrary. In addition, there are also cases where it becomes non-displayed by the operation of the refresh tile described later.

  In addition, the 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 at one place in the artwork screen D1, regardless of the set music feature amount. Also, a tile that is displayed large at the center of the touch panel TP indicates the artwork of the music being played. On the other hand, in the case of 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 an operation on each of the screens D1 and D2 displayed on the touch panel TP. For example, in the artwork mode, replacement of artwork and reproduction start instruction are performed. Also, in the case of 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 the present 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 indicates information that serves as a reference when classifying music. Therefore, in addition to these three types, “age”, “artist”, “BPM (Beats Per Minute)”, “key (Key)” and the like can be set.

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

  The recommendation degree determination unit 140 determines the recommendation degree of each music based on one or more elements among “user preference”, “user's biometric information”, and “environment information” for each music list. Which element of these 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 for the same music, the degree of recommendation calculated is different depending on the classified music list. In the music list shown in FIG. 2B, identification information (music ID) of each music is listed in descending order of recommendation degree. In addition, a recommendation degree is represented, for example with 100 steps of "1-100" (refer to parenthesis writing after each music ID).

  Here, “user preference” is the operation history of each music data (the number of times of reproduction of each music data, the total number of times of reproduction, the number of times of search, the number of times of audition, etc. of purchase) It is judged based on. That is, the music determined to be the user's preference from the operation history has a high degree of recommendation. Also, “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). In addition, what is employ | adopted as biometric information is set by 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 in a state of being excited, the degree of recommendation of music having a low sense of activity (low EPM value) is high.

  The "environmental information" is determined based on the traveling position of the vehicle and / or the traveling state of the vehicle. In addition, what is adopted as environmental information is set on the status screen D2. In addition, “traveling position of the vehicle” is registered in the area type (sea, mountain, city area etc.), road type (highway, national road, prefectural road, municipal road etc.), nearest tourist spot, navi unit 12 Point and marked point. The “traveling position of the vehicle” can be detected by acquiring current position information from the navigation unit 12. In addition, the “traveling state of the vehicle” refers to the traveling speed, the swinging condition of the vehicle (slip, sway, deviation from oblique lines, etc.), the frequency of braking, and the like. The “traveling state of the vehicle” can be detected by acquiring the measurement results of the acceleration sensor 42 and the vibration sensor 43 from the vehicle control device 4. When determining the degree of recommendation based on "environmental information", for example, if the current travel position is near "sea", the degree of recommendation of a song related to the ocean (a song to which a keyword related to the ocean is added as metadata) When the vehicle becomes more unstable, the recommendation of music with high BPM becomes higher to prevent sleepiness.

  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. 2 (b) is generated, as shown in FIG. 3, as many songs as the artwork screen D1 can display (in the example of FIG. 3) , 16), select and display. Note that “***” in the notation (AW-***) of each artwork is the music feature amount (G: genre, H: hit chart, E: EPM) of the corresponding music, and the order in each music list ( 2 digits are shown.

  In addition, the display control unit 150 arranges the artworks of the music pieces belonging to the same music list in proximity on the artwork screen D1, and replaces the artworks to be displayed according to the passage of time. In the present embodiment, the artwork is replaced every predetermined time t2 (periodically). In addition, if at least one of "user's biometric information" and "environment information" changes, the artwork is replaced. It should be noted that the replacement of the artwork gives priority to the artwork of the music having a low recommendation degree in each music list among the artworks displayed on the touch panel TP. For example, if five artworks with a recommendation degree of 1st to 5th are displayed for any music list, the artwork with a recommendation degree of 5th place is replaced with the artwork with a recommendation degree of 6th at first, and the next timing Then, display control is performed such as replacing the artwork with the recommendation degree 4th with the artwork with the recommendation degree 7th. It should be noted that a predetermined number of artworks from the top of the recommendation degree may not be replaced by the setting of the status screen D2.

  In addition, when a flick operation (an operation having a first directivity) toward the outside of the touch panel TP having an arbitrary artwork as a starting point (starting point) is performed by the display control unit 150 using the operation unit 120, the arbitrary Replace the artwork of with other artwork not shown. The “flick operation” refers to an operation of touching the screen so as to quickly clear it. In addition, when the feature amount tile indicating the music feature amount of each music is touched by the operation unit 120, the art of the music in the music list corresponding to the touched feature amount tile is displayed for all the artworks displayed Switch to work. Further, when the refresh tile arranged at one place on the touch panel TP is touched by the operation unit 120, all displayed artworks are replaced.

  In addition, the display control unit 150 is a collection of artworks by feature amount that is a collection of artworks of music belonging to the same music list (the alphabet of the first "*" of each artwork (AW-***) is the same) In the example of FIG. 3, the display position in the touch panel TP, which is denoted by E02 to E04, is changed according to the passage of time. In the present embodiment, the display positions of the artwork groups by feature amount (display positions of the artworks making up the artwork group by feature amount) are gradually rotated clockwise (periodically) every predetermined time t1. Rotate.

  The reproduction control unit 160 starts the reproduction of the music corresponding to the arbitrary artwork when the flick operation toward the inside of the touch panel TP starting from the arbitrary artwork is performed on the artwork screen D1. In addition, after the music reproduction ends, automatic reproduction (automatic selection / automatic reproduction 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 degree of recommendation. Note that the reproduction control unit 160 performs automatic reproduction after the display start of the artwork screen D1 until the reproduction start operation is performed by the user.

  Next, the configuration of the artwork screen D1 will be described with reference to FIG. In the artwork screen D1, as shown by the code E01, the artwork of the music being played (the music of "AW-E04" in the example in the figure) is largely displayed at the center of the touch panel TP (a reproduced music display area E01). Although the reproduction music display area E01 is four times as large as the other artworks in the example of the figure, it may be set as the size desired by the user. In addition, the size of the artwork (artwork of the music being not reproduced) other than the reproduction music display area E01 may be set. The size of the artwork may be set as an absolute value, for example, in mm units or display pixel units, or may be set as a relative value such as large, medium, or small.

  Further, as indicated by reference symbols E02 to E04, artwork groups by feature amount are displayed respectively corresponding to three types of music feature amounts "genre", "hit chart", and "EPM" (a feature amount display area) E02 to E04). Also, each feature amount tile (“GENRE REFRESH”, “HIT CHART REFRESH”, “EPM REFRESH”) indicating the corresponding feature amount is arranged so as to contact at least one artwork in each feature amount artwork group Do. Although the feature amount tile is set to the same size as the surrounding artwork in the example of the figure, it may be set as the size desired by the user.

  Further, as indicated by reference symbols E02 to E04, the artwork and the feature amount tile belonging to the same feature amount classified artwork group are displayed with the same decoration. In the present embodiment, a frame of the same color is added for each music feature amount as a decoration (in the drawing, the color of the frame is expressed by the difference in the filling pattern). Note that the music feature amount and the color of the frame 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 amounts, the frame of "genre" is red, the frame of "hit chart" is blue, and the frame of "EPM" is If it is yellow and two “hit chart” and “EPM” are selected, the number of selected music feature amounts or selection, such as setting the “hit chart” frame in red and the “EPM” frame in blue The setting color is changed according to the order. Further, the display position of the artwork group classified by feature amount on the touch panel TP is determined according to the color of the set frame. In the present embodiment, the arrangement order of artwork groups by feature amount in an arbitrary rotation direction centering on the reproduction music display area E01 is determined in accordance with the hue circle.

  Further, as indicated by a symbol E05, the refresh tile is displayed at only one place on the touch panel TP (refresh tile display area E05). The refresh tile is decorated with a decoration different from the decoration added to each feature amount artwork group.

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

  As shown in FIG. 4, the display areas E02 to E04 by feature amount are slightly moved in the clockwise direction centering on the reproduction 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. Furthermore, the refresh tile display area E05 also moves clockwise as the other tiles move. Further, in FIG. 4, the artwork to be displayed is also replaced. In this case, the artwork of the music with a low recommendation degree is preferentially replaced in each music list. For example, in the display area E02 classified by feature amount of "genre", two artworks ("AW-G07" and "AW-G08") are not displayed as compared with the state shown in FIG. Moreover, in the display area E03 classified by feature amount of the “hit chart”, one artwork (“AW-H06”) is added, and in the display area E04 classified by feature amount of “EPM”, one artwork (“AW E05 ") has been added. Further, in each of the feature amount-by-feature amount display areas E02 to E04, rearrangement of artwork is also performed along with exchange of artwork. Artwork rearrangement is based on a predetermined algorithm such as random arrangement.

  Next, the flow of display control in the on-vehicle device 1 will be described with reference to the flowchart in FIG. Here, it is assumed that the user does not perform the work of replacing artwork. The in-vehicle device 1 (display control unit 150) determines whether a predetermined time t1 has elapsed from 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 classified by feature amount is rotated (S02). Moreover, when the predetermined time t1 has not passed (S01: No), S02 is abbreviate | omitted.

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

  Next, with reference to FIGS. 6 to 11, the change of the artwork screen D1 accompanying the user operation will be described. As shown in FIG. 6, starting from an arbitrary artwork (“AW-H04” in the example of FIG. 6), the flick operation is performed 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, in place of any artwork, another artwork is displayed (in the example of FIG. 7, "AW-H06"). However, replacement with another artwork is conditional on being belonging to the same music list as the music corresponding to any artwork.

  In addition, as shown in FIG. 8, flicking operation toward the inside of the touch panel TP (for example, in the direction of reference numerals 65 and 66) from an arbitrary artwork (“AW-H04” in the example of FIG. When is performed, as shown in FIG. 9, an arbitrary artwork is displayed on the reproduced music display area E01, and the reproduction of the music corresponding to the arbitrary artwork is started. In addition, in the area where any artwork is displayed, another artwork is displayed instead of any artwork (in the example of the figure, “AW-H06”). Also in this case, replacement with another artwork is conditional on belonging to the same song list as the song corresponding to any artwork.

  Further, as shown in FIG. 10, when any feature amount tile (“GENRE REFRESH” in the example of FIG. 3) is touched from the state of FIG. 3, all the artwork displayed on the touch panel TP and A feature amount tile other than an arbitrary feature amount tile ("HIT CHART REFRESH", "EPM REFRESH" in the example of the figure) is replaced with the artwork of the music in the music list corresponding to the touched feature amount tile. That is, in the example of the same figure, all the displayed artworks become artworks of music belonging to the music list of "genre". In this case, replacement and rearrangement of artworks in the feature amount classified display area E 02 of “genre” are not performed. Further, the reproduction music (display of reproduction music display area E01) and the display position of the refresh tile display area E05 also do not change.

  Further, as shown in FIG. 11, when the refresh tile (“ALL REFRESH”) is touched from the state of FIG. 3, all 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 reproduction music (display of reproduction music display area E01) and the display position of the refresh tile display area E05 also do not change. Furthermore, the display position of each feature amount classified display area E02 to E04 and the number of artworks constituting each feature amount classified artwork group do not change.

  Next, the configuration of the status screen D2 will be described with reference to FIG. 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 reproduced 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 reproduced 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 disposed, and around it, concentric with the reproduction music display area E11 and having 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 degree setting area E14, and a sound setting area E15 are arranged so as to divide a large circular area in a fan shape. The reproduced music information area E12 displays metadata of the music being reproduced and a source (recording media such as the memory 11, the music memory 22, and the music database 51). Further, the reproduction music operation area E13 displays a graphical user interface (GUI) related to reproduction music operation such as a play / pause button, a fast-forwarding / rewinding button, and the like mounted on a general audio device.

  The recommendation degree setting area E14 is an area for selecting and setting each condition for determining the recommendation degree, and displays selection buttons and setting areas for the following items. In the recommendation degree setting area E14, selection of music feature amount (selection of feature amount type such as "genre", "hit chart", "EPM", "age", and detailed setting thereof (designation of "genre", "age" And so forth), selection of parameters for determining the recommendation degree (for each music list, which element is adopted among “user preference”, “user's biometric information” and “environment information”, and its weighting) Setting), selection of biological information (which one of the temperature sensor 32 and the heart rate sensor 33 is adopted), selection of environmental information (which one of the “traveling position” and “traveling place” of the vehicle is adopted), Selection of a source (which one of the memory 11, the music memory 22, and the music database 51 is to be targeted) is performed. When the setting change is performed in the recommendation degree setting area E14, the degree of recommendation of each music list is affected, so the display of the artwork screen D1 is updated.

  Further, the sound setting area E15 displays a GUI related to the sound setting that is mounted on a general audio device, such as a setting area for performing equalizer setting and volume setting, and display of a spanner (music waveform).

  Further, a link display area E16 is disposed in the lower right portion of the status screen D2. The link display area E16 indicates a link state of the in-vehicle device 1 and the bracelet 3 by ON / OFF of an image imitating the bracelet 3. When the in-vehicle apparatus 1 and the bracelet 3 are in the non-linked state, the biological information does not affect the recommendation degree of the music list “EPM” even when the biological information is selected in the recommendation degree setting area E14.

  As described above, according to the present embodiment, the artwork of one or more music pieces belonging to each music list classified by feature amount is tiled and displayed on the touch panel TP and displayed on the artwork screen D1. Since the target artworks are replaced according to the passage of time, the music can be presented nicely in comparison with the conventional playlist in which the music titles are listed according to the reproduction order. Also, by replacing the artwork, it is possible to always present fresh music to the user. Further, by expanding the music source source such as the external server 5, it is possible to expect encounters with unexpected music that the user has never heard before.

  In addition, when the user does not perform any operation, there is no need to operate the music selection operation by the automatic reproduction, so that the user while driving is not bothered. On the other hand, it is also possible to change or stop music by user operation. As described above, according to the present embodiment, it is possible to realize the method of presenting music with the disadvantages eliminated by using the merits of the radio.

  Further, according to the present embodiment, in the artwork screen D1, the artwork is replaced with another artwork because the artwork is replaced with another artwork by a flick operation toward the outside of the touch panel starting from the artwork. Can easily be done in one step. Moreover, since it is also possible to collectively replace a plurality of music pieces by touching the feature amount tile or the refresh tile, the operation is further facilitated. In addition, since the music corresponding to the arbitrary artwork is started to be reproduced by the flicking operation toward the inside of the touch panel starting from the arbitrary artwork, the reproduction operation can be easily performed in one step.

  In addition, since the screen can be switched to the status screen D2 by touching the artwork of the music being played (reproduced music display area E01) displayed at the center of the artwork screen D1, the menu screen is displayed and desired. As compared with the conventional screen switching method of switching to the screen of, it is possible to perform confirmation and detail setting of detailed information with fewer steps.

  In addition, the following modification is employable. For example, although the display control unit 150 of the above embodiment displays the artwork of all the songs except the artwork of the song being reproduced in the same size (see FIG. 3 etc.), according to the degree of recommendation of each song The display size of each artwork may be variable. That is, the artwork of the highly recommended music may be displayed larger than the artwork of the less recommended music. According to this configuration, the user can grasp the recommendation degree of the music at a glance.

  In the above embodiment, the color of the frame to be added to the artwork is changed as the decoration for each music feature amount, but the pattern (pattern) of the frame can be changed together with the color of the frame instead of the color of the frame. You may. Also, the background color of each artwork (tile) may be changed, or a predetermined mark may be added instead of the frame.

  Further, as a modification, instead of setting the frame color for each music feature amount, an intermediate color of two types of music feature amounts may be set. For example, a reddish-purple frame for an artwork corresponding to a song whose recommendation degree of “genre” set to red is “1” and recommendation degree of “hit chart” set to blue is “5” May be added. Thereby, the gradation can be formed in the entire artwork, and the appearance can be further improved. Further, since the user can estimate two types of music feature amounts from the color of the frame, the user can more intuitively select music.

  Further, in the above embodiment, although the disc jacket of the music is illustrated as the artwork, the present invention is not limited to this. For example, an original image created by the user for the music may be used as the artwork. That is, "artwork of music" in the claims means 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 biometric information" and "environment information" Although it is assumed that the artwork is replaced when the () changes (see FIG. 5), the rotation of the artwork group by merit and the replacement of the artwork may be performed at the same timing. Further, the presence / absence or rotation direction of the artwork group by feature amount, the presence / absence of replacement of artwork, replacement algorithm, and predetermined times t1 and t2 may be made variable by setting.

  Further, in the above embodiment, when performing replacement of artworks or instructing to start reproduction, the “operation on any artwork” is an operation starting from any artwork, but any art It may be defined as an operation that uses a work as an end point, or an operation that uses any artwork as a passing point. Further, among these, it may be possible to set in the status screen D2 by which operation the replacement of the artwork or the reproduction start instruction is performed.

  In the above embodiment, the flick operation directed to the outside of the touch panel TP is exemplified as the operation (the operation having the first directionality) for replacing the artwork, but the upward direction, other than the outside, The lower direction, the right direction, the left direction, the right oblique direction, and the left oblique direction may be defined as one or more. Also, it may be defined as the inside. Similarly, the flick operation directed to the inside of the touch panel TP has been exemplified as the operation for instructing the start of reproduction (the operation having the second directionality), but it may be defined as one or more of the above options . In addition to the flick operation, other operations with directionality such as drag operation, pinch in (pinch close) / pinch out (pinch open), etc. may realize replacement of artwork and start of reproduction.

  In the above embodiment, in the recommendation degree setting area E14 of the status screen D2, although a parameter for determining the recommendation degree is set for each music list, as a parameter common to all the music lists, You may set it collectively.

  Moreover, in said embodiment, although the biometric information of a vehicle passenger (driver) was detected by the bracelet 3, you may detect biological information by another apparatus (for example, a thermometer and a heartbeat measuring device). Further, the portable terminal 2 may be provided with a detection function of biological information (body temperature sensor 32 and heart rate sensor 33).

  Further, although the artwork is displayed for the purpose of presenting the music to the user in the above embodiment, the present invention is also applicable to the case where contents other than the music data (video, still image, etc.) are presented. .

  Moreover, in said embodiment, although the display part 110 and the operation part 120 were implement | achieved by the touch panel TP, you may implement | achieve with each separate hardware. Moreover, although the case where this invention was applied to the vehicle-mounted apparatus 1 was illustrated in said embodiment, this invention is applicable also to another electronic device (a display apparatus, the operating device).

  In addition, it is possible to provide each component of the in-vehicle system SY described above as a program. It is also possible to store the program in various recording media (CD-ROM, flash memory, etc.) and provide it. That is, a program for causing a computer to function as each component of the in-vehicle system SY, and a recording medium recording the same are also included in the scope of the present invention. In addition, changes can be made as appropriate without departing from the scope of the present invention.
