Hereinafter, preferred embodiments of a music support apparatus, a music support method, a music support program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

[0016] (Embodiment 1)

(Schematic configuration of music support device)

FIG. 1 is a block diagram showing a schematic configuration of the music support apparatus according to the first embodiment. The music support apparatus according to Embodiment 1 includes an extraction unit 101, a determination unit 102, an output unit 103, a calculation unit 104, an acquisition unit 105, a determination unit 106, and a detection unit 107. The music support apparatus according to Embodiment 1 is mounted on a moving body such as a vehicle, for example.

[0017] The extraction unit 101 extracts information about the characteristics of the route to the destination point. The route may be a route from the current location to the destination location, or a route from any location to the destination location. The extraction unit 101 extracts, for example, information about features related to the shape of the route. Further, the extraction unit 101 may extract, for example, information related to features related to a route stop point.

[0018] Based on the information on the feature extracted by the extraction unit 101, the determination unit 102 determines the music content associated with the information on the feature. Here, the music content is specifically digital information for playing a music for viewing purposes by playing it. The determination unit 102 may determine the music content based on the past appreciation history.

[0019] The determining unit 102 may determine the music content according to the state of the viewing target based on the detection result detected by the detecting unit 107. Specifically, for example, the decision unit 102 provides information on characteristics up to the destination point and information on the status of the audience. The music content may be determined by searching a database that stores the music content in association with the music content. For example, in the case where a music support device is mounted on a vehicle, the audience is a person who is on the vehicle.

The output unit 103 outputs the music content determined by the determination unit 102. The output unit 103 may output the music content according to the timing calculated by the calculation unit 104. The output unit 103 may output the music content determined to be output by the determination unit 106. The calculating unit 104 calculates the output timing of the music content determined by the determining unit 102 based on the position of the feature portion extracted by the extracting unit 101 on the route.

The acquisition unit 105 acquires sample content that is a part of the music content determined by the determination unit 102. The determining unit 106 determines whether or not to output music content including the sample content acquired by the acquiring unit 105. The detecting unit 107 detects the state of the person who is viewing the music content. For example, the detection unit 107 detects the state of the viewing target person by analyzing ambient environmental sound collected using a microphone. In addition, the detection unit 107 may detect the state of the person to be watched by analyzing surrounding images taken using a camera, for example.

[0022] (Processing procedure of music support apparatus)

FIG. 2 is a flowchart showing a processing procedure of the music support apparatus according to the first embodiment. In the process shown in FIG. 2, it is first determined whether or not a route to the destination point has been acquired (step S201). If it is determined that the route to the destination point has not been acquired (step S201: No), the process waits as it is. If it is determined that the route to the destination point has been acquired (step S201: Yes), information on the characteristics of the acquired route is extracted (step S202). In the present embodiment, the extraction process is realized by the process of step S202.

[0023] In step S202, for example, when extracting information related to characteristics related to the shape of the route, information such as height difference (such as ups and downs, altitude, etc.) of the route, curve of the curve, speed, and road width are included. Based on this, information on route characteristics is extracted. In step S202, for example, the feature related to the route stopover When extracting information related to the route, information on the characteristics of the route is extracted based on whether it is a tourist spot, whether it is a large-scale commercial city, whether there is a landmark, or the like. In addition, the status of the person who is viewing the music content is detected (step S203).

Next, the music content is determined based on the information on the extracted features or the detected state of the audience (step S204). In the present embodiment, the determination process is realized by the process of step S204. In step S204, for example, the corresponding music content is determined by searching a music database provided in advance based on information on the characteristics of the route and the state of the audience. In the music database, for example, information that is considered as a feature of the route and information that is considered as the state of the audience is stored in association with the music content.

Subsequently, based on the determined music content, sample content that is a part of the music content is acquired (step S205). The sample content may be configured by extracting data of a predetermined size from the start position of the music content, or may be configured by predetermined data set in advance.

[0026] Then, it is determined whether or not to output music content including the acquired sample content (step S206). The determination in step S206 is performed based on an input operation by the user. As a result of viewing the sample content, the user performs an input operation not to output the music content when it is determined that the music content including the sample content is unnecessary. On the other hand, when requesting music content including the viewed sample content, an input operation to that effect is performed. If it is determined that the music content including the acquired sample content is not to be output (step S206: No), the process ends.

If it is determined that the music content including the acquired sample content is to be output (step S206: Yes), the music content is output (step S207). In the present embodiment, an output process is realized by the process of step S207. In step S207, the music content is reproduced by, for example, playing the music content using a computer, D / A converting the resulting reproduction signal, and amplifying it through a speaker. Output.

[0028] As described above, according to the music support apparatus in the first embodiment, based on the information on the characteristics of the route to the destination point, the music content associated with the information on the characteristics is output. Therefore, the music content associated with the route to the destination point can be acquired at the stage when the route is determined. As a result, it is possible to output the music content associated with the route to the destination point without the user's work.

[0029] Further, according to the music support apparatus in the first embodiment, the music content is output according to the output timing calculated based on the position of the extracted feature portion on the route. Therefore, the music associated with the route to the destination point can be output according to the timing of passing the characteristic portion on the route.

By the way, in the music support apparatus according to Embodiment 1, after acquiring sample content that is a part of the determined music content, it is determined whether or not to output music content including the sample content. Then, the music content determined to be output is output. Therefore, for example, it is possible to prevent output of music content that does not match the user's image, or to prevent excessive output of music content.

[0031] In the music support apparatus in the first embodiment, when information related to the feature related to the shape of the route is extracted, the music associated with the shape of the route that travels is output. As a result, even if the user (especially the driver) is not suitable for performing music playing operations, such as when passing through a path with continuous curves or a forest road with severe undulations, The music associated with the route to the point can be output immediately through the user's work.

[0032] Similarly, in the music support apparatus according to the first embodiment, when information related to the characteristics related to the route via point is extracted, the music associated with the route via point of passage is output. As a result, for example, even when the user has no knowledge about the waypoint, it is possible to output the music associated with the route to the destination point without going through the user's work.

[0033] Furthermore, in the music support apparatus according to Embodiment 1, based on past appreciation history. The music content is determined. As a result, it is possible to output music that is associated with the route to be traveled and that is suitable for the user's preference.

[0034] In addition, the state of the appreciation target person of the music content is detected, and the music content corresponding to the state of the appraisal target person is determined based on the detection result. As a result, it is possible to output music suitable for the route to be traveled and the state of the audience.

In the process shown in FIG. 4, first, it is determined whether or not information on the current location and the destination location of the mobile object has been received (step S401). In FIG. 4, the process of step S401 is described as “Did you receive the current location / target location of the moving object?”. If it is determined that information on the current location and the destination location of the mobile unit has not been received (step S401: No), the system waits as it is.

[0038] If it is determined that information on the current location and the destination location of the mobile body has been received (step S401: Yes), a route search is performed based on the received information on the current location and destination location (step S402). . In step S402, an optimum route is searched for in accordance with the preset priority conditions, etc., among the routes from the current location to the destination location. In the second embodiment, the reception is performed by the process of step S401: Yes. The communication process is realized.

Next, information about the acquired route characteristics is extracted (step S403). In the second embodiment, the extraction process is realized by the process of step S403. In step S 403, as in step S 202 in FIG. 2, for example, information related to the feature related to the route shape, information related to the feature related to the route stop point, and the like are extracted.

[0040] Then, the music content is determined based on the extracted information about the feature (step S404). In the second embodiment, the determination process is realized by the process of step S404. Based on the determined music content, it is determined whether or not the sample content that is a part of the music content is transmitted to the mobile body (step S405). In FIG. 4, “Send sample content?” Is described as the process of step S405.

[0041] In step S405, for example, the presence / absence of necessity for transmission of sample content may be determined by performing wireless communication with a mobile unit. In step S401, information indicating the necessity of content transmission may be received in advance in addition to information on the current location and the destination location of the mobile object.

[0042] When it is determined that the sample content is to be transmitted to the mobile body (step S405: Yes), the sample content is transmitted to the mobile body that is the transmission source of the information on the current location and the destination location. (Step S406). If it is determined that the sample content is not transmitted to the moving body (step S405: No), the process proceeds to step S408.

Next, it is determined whether or not the music content is transmitted to the mobile body (step S 407). When it is determined that the music content is to be transmitted (step S407: Yes), the music content is transmitted to the mobile body (step S408). In the second embodiment, the transmission process is realized by the process of step S408. If it is determined that the music content is not to be transmitted (step S407: No), the process is terminated as it is.

[0044] As described above, according to the music support apparatus in the second embodiment, the receiving unit 201 and the transmitting unit 202 communicate with the moving body so that the mobile body is installed separately from the moving body. The obtained music support apparatus also obtains the same effects as those of the first embodiment described above. That power S.

In addition, a memory area for storing information associated with the departure route is provided in the RAM 503 in the ROM 502. The predetermined memory area stores information in a non-volatile manner regardless of whether the engine equipped with the navigation device is ONZOFF.

[0058] In the memory 503 in the ROM 502, for example, a memory that stores information on the route searched (including re-search) by the CPU 501 or information on the destination point set at the time of searching for the route in a rewritable manner. An area may be secured. These various memory areas are not limited to those secured in ROM502 or RAM503, but may be secured in HD517, for example. These various memory areas are not limited to those provided in the navigation device, and may be provided in a server, for example.

The operation key 504 outputs information input by the user, such as characters, numerical values, and various instructions, to the input I / F 505. The input I / F 505 outputs information input from the operation key 504 to the CPU 501. As the configuration of the operation key 504, various known forms such as a push button switch for detecting physical depression / non-pressing, a touch panel, a keyboard, and a joystick can be employed. The operation key 504 may be configured to perform an input operation by voice using a microphone 510 that inputs voice from the outside.

[0060] The operation key 504 may be provided integrally with the navigation device, or may be configured to be operated separately from the navigation device, such as a remote control. The operation key 504 may be configured in any one of the various forms described above, or may be configured in a plurality of forms.

The user inputs information by appropriately performing an input operation according to the form of the operation key 504. Examples of information input by operating the operation key 504 include a destination point.

The received traffic information is used when searching for a route (including re-searching), and is used, for example, for searching for a route that avoids traffic jams and time restriction points.

[0074] The ability to omit detailed explanations because it is a well-known technology "VICS" means that traffic information such as traffic jams and traffic regulations that have been edited and processed at the VICS center is sent in real-time and written to car navigation systems. 'It is an information communication system that displays graphics. Edited by VICS center one, as a method for transmitting the processed traffic information (VICS information) to car navigation device, a method forces ^s use is installed on each road as "beacon" to "FM multiplex broadcasting" .

“Beacons” include “radio wave beacons” mainly used on expressways and “optical beacons” used on major general roads. When “FM multiplex broadcasting” is used, traffic information in a wide area can be received. When using a “beacon”, it is possible to receive necessary traffic information at the location where the vehicle is located, such as detailed information on the most recent road based on the location of the vehicle.

[0076] 0/0 ¥ 0 drive 515 controls reading and writing of information on CD (CD-ROM, CD-R, CD-RW, etc.) and DVD. Although not shown in FIG. 5, for example, arbitrary music content may be stored on the CD / DVD by the user.

[0077] Instead of or in addition to CDZDVD, MO (Magneto-Optical disk), memory A portable storage medium such as a card may be used. When a portable storage medium such as an MO or memory card is used, a dedicated drive device that controls the reading / writing of information to the portable storage medium such as an MO or memory card will be installed separately.

An HDD (Hard Disk Drive) 516 controls reading / writing of information with respect to an HD (Hard Disk) 517. The HD517 records various control programs and various information so that they can be read by a computer. In the first embodiment, it is assumed that a music support program for realizing the present invention is recorded in HD517.

Note that the music support program for realizing the present invention is not limited to the one recorded in HD517. Instead of HD517, a music support program stored in a portable medium such as CDZDVD may be executed. The HD 517 accepts writing of information by the HDD 516 and records the written information in a nonvolatile manner.

[0080] Map information is recorded in HD517. Map information is used for route search and route guidance by CPU501. The map information includes background information that represents features (features) such as buildings, rivers, and the ground surface, and road shape information that represents the shape of the road, and can be displayed in two or three dimensions on the display screen of the display 506. Drawn.

The background information includes background shape information representing the shape of the background and background type information representing the type of the background. The background shape information includes, for example, information indicating feature points, polylines, polygons, feature coordinates, and the like. The background type information includes, for example, text information indicating the name, address, telephone number, and the like of the feature, type information indicating the type of the feature such as a building “river”, and the like.

[0082] The road shape information is information relating to a road network having a plurality of nodes and links. The node is information indicating an intersection where a plurality of roads intersect, such as a three-way “crossroad” and a five-way. A link is information indicating a road connecting nodes. Some links have shape interpolation points that allow the expression of curved roads. Road shape information has traffic condition information. The traffic condition information is information indicating the characteristics of the intersection, the length (distance) of each link, vehicle width, traveling direction, traffic prohibition, road type, and the like.

[0083] The characteristics of the intersection include, for example, a complicated intersection such as a three-way or a five-way and a shallow corner. These include intersections where roads diverge at different degrees, intersections around destination points, highway entrances and junctions, and intersections with a high route departure rate. The route departure rate can be calculated from, for example, past travel history. Examples of road types include highway, toll road, and general road.

[0084] In this embodiment, the power to record the map information on HD517 is not limited to this. The map information may be provided outside the navigation device, not the one recorded with the navigation device hardware. In this case, the navigation device acquires map information from the outside of the navigation device through communication IZF514, for example. The acquired map information may be recorded in HD517, or stored in RAM503 or CD / DVD.

[0085] HD 517 is provided with a music database (not shown) that stores information related to route characteristics and music content in association with each other. Information on route characteristics includes, for example, height differences in the route (such as ups and downs and altitudes), presence or absence of curves, and information such as roads. Information on the characteristics of the route includes information such as the frequency of traffic jams and latitude / longitude.

[0086] Information on the characteristics of the route is not limited to information on the road itself. As other information on the characteristics of the route, for example, information on the characteristics related to the waypoint of the route can be cited. Information on the characteristics related to the waypoints of the route includes information such as whether or not it is a tourist destination \ whether or not it is a large-scale commercial city and whether or not there is a landmark.

[0087] Information regarding the characteristics of the route is associated with each piece of music content. In the music database, information related to the situation in which music content has been determined in the past is associated. Examples of information on the determined situation include weather, time 時 ij, and the like.

[0088] In the music database, information related to the in-vehicle atmosphere is associated with each music content. Examples of information related to the atmosphere in the vehicle include information related to the state of a passenger (a person who appreciates music content) of a vehicle equipped with a navigation device. [0089] Specifically, as the information on the passenger's state, for example, the state of the person to be viewed is detected by analyzing surrounding environmental sounds collected using a microphone. In addition, the detection unit 107 may detect the state of the person to be viewed by analyzing surrounding video captured using a camera, for example.

[0090] Further, the music content is associated with a sample content that is a part of the music content. The sample content is data for viewing that allows a part of the music content to be viewed. For example, the sample content may be configured by extracting data of a predetermined size from the start position of the music content, and may be configured by a predetermined amount of data set in advance. Anyway.

FIG. 6 is a flowchart illustrating a processing procedure of the navigation device according to the first embodiment. The process shown in FIG. 6 first determines whether or not a route search has been instructed (step S601). If it is determined that route search is not instructed (step S601: No), the process waits as it is.

If it is determined that a route search has been instructed (step S601: Yes), it is determined whether information regarding the destination point is set (step S602). In FIG. 6, as the processing of step S602, “Does the destination point be set?” Is entered.

When it is determined that the information regarding the destination point is not set (step S602: No), information requesting the setting of the destination point is notified (step S603). The information for requesting the setting of the destination point may be displayed on the display 506 with the screen requesting the setting of the destination point, and even if the audio requesting the setting of the destination point is output from the speaker 509, the screen table Both display and audio output may be used.

[0094] Then, it is determined whether or not a predetermined time has elapsed since the information requesting the setting of the destination point was notified (step S604). If it is determined that the predetermined time has not elapsed (step S604: No), the process proceeds to step S602. If it is determined that the predetermined time has elapsed (step S604: Yes), the process is terminated as it is.

[0095] If it is determined that the information on the destination point is set (step S602: Yes), the route search from the current point to the target point is performed based on the information on the current point and the information on the destination point. Perform (step S605). In step S605, your current location The route from the point to the destination point may be searched instead of being limited to the route from the point to the destination point. In the first embodiment, after the route search, the movement is started at an arbitrary timing according to the searched route, and the route guidance according to the route searched in Step S605 is started with the start of the movement.

[0096] Next, based on the searched route, information on the feature of the route is extracted.

(Step S606). In step S606, for example, when the searched route includes a portion that passes along the coast, the coast, sea, water, and the like are extracted as characteristic portions of the route.

[0097] Further, the state of the driver and passengers (hereinafter referred to as passengers) of the vehicle equipped with the navigation device is detected (step S607). The music database is searched based on the information on the route characteristics and the passenger's state (step S608), and it is determined whether or not there is corresponding music content (step S609). If it is determined that there is no corresponding music content (step S609: No), the process is terminated as it is.

[0098] In step S609, for example, when a coastal part of the searched route is extracted as a characteristic part of the route, the music content associated with the sea (or reminiscent of the sea) is displayed as the corresponding music. Determine as content.

If it is determined that the corresponding music content exists (step S609: Yes), it is determined whether or not sample content is to be acquired (step S610). In step S610, whether or not to acquire sample content may be set in advance or may be set as appropriate. If it is determined that the sample content is not acquired (step S610: No), the process proceeds to step S614.

[0100] When it is determined that the sample content is acquired (step S610: Yes), the sample content is acquired (step S611), and it is determined whether or not the acquired sample content is played back (step S612). In step S612, whether or not to play the acquired sample content may be set in advance, or may be set appropriately each time sample content is acquired.

[0101] If it is determined not to play the acquired sample content (step S612: No ), Go to step S614. If it is determined that sample content is to be played back (step S612: Yes), the acquired sample content is played back (step S613).

[0102] Next, it is determined whether or not to acquire music content (step S614). In step S614, it is determined whether or not the music content including the sample content determined in step S610 is acquired. If it is determined that the music content is not acquired (step S614: No), the process is terminated.

[0103] If it is determined that the music content is to be acquired (step S614: Yes), the target music content is acquired (step S615). In FIG. 6, “song content acquisition” is described as the process of step S615. After that, it waits until it is determined that it is time to play the acquired music content (step 616: No).

[0104] For example, when a coastal part of a searched route is extracted as a characteristic part of the route and music content associated with the sea (or reminiscent of the sea) is determined, navigation is performed. The timing when the vehicle carrying the device passes along the coast and in the vicinity thereof is determined as the regeneration timing.

When it is determined that it is time to reproduce the acquired music content (step 616: Yes), the acquired music content is reproduced (step S617). Thereafter, it is determined whether or not the destination point has been reached (step S618). If it is determined that the destination has been reached (step S618: Yes), the process is terminated as it is. At the same time, the route guidance is terminated.

If it is determined that the destination has not been reached (step S618: No), it is determined whether there is any other music content (step S619). If it is determined that there is another music content (step 619: Yes), the process proceeds to step S616. If it is determined that there is no other music content (step 619: No), the process is terminated.

[0107] As described above, according to the navigation device in the first embodiment, based on the information on the feature of the route to the destination point, the music content associated with the information on the feature is output. Therefore, the music associated with the route to the destination point can be determined when the route is searched. As a result, the music associated with the route to the destination point can be played back without the user's work, and entertainment can be improved. [0108] Also, according to the navigation device in the first embodiment, the music content is output according to the output timing calculated based on the position of the extracted feature portion on the route. Therefore, the music associated with the route to the destination point can be output according to the timing of passing the characteristic part in the route.

By the way, in the music support apparatus according to the first embodiment, after acquiring the sample content that is a part of the determined music content, whether or not to output the music content including the sample content is determined. When it is determined and output, the determined music content is output. Therefore, for example, output of music content that does not match the user's image can be prevented, or output of excessive music content can be prevented.

[0110] In the music support apparatus according to the first embodiment, when information related to the feature related to the shape of the route is extracted, the music associated with the shape of the route that travels is output. As a result, even if the user (especially the driver) is not suitable for performing music playing operations, such as when going through a path with continuous curves or a forest road with undulations, The music associated with the route to the point can be output without the user's work.

[0111] Similarly, in the music support apparatus according to the first embodiment, when information related to the feature related to the route via point is extracted, the music associated with the route route along which the route passes is output. Thereby, for example, even when the user has no knowledge about the waypoint, the music associated with the route to the destination can be output without going through the user's work.

Furthermore, in the music support apparatus according to the first embodiment, the music content is determined based on the past appreciation history. As a result, it is possible to output music that is associated with the route to be traveled and that is suitable for the user's preference.

[0113] The state of the appreciator of the music content is detected, and the music content corresponding to the state of the appraisal target is determined based on the detection result. As a result, it is possible to output music suitable for the route to be traveled and the state of the audience.

[0114] Here, as a specific example, for example, when traveling near a leisure facility such as an amusement park, a light up-tempo musical piece is played to create a pleasant atmosphere. You could think so. However, when going through the same point, if you are going to go home and your child is sleeping in the car, a light uptempo music will be played. There is a concern that the child may wake up, or that he / she has departed to the amusement park. On the other hand, it is possible to further improve the entertainment properties by outputting music that takes into consideration not only the route to be taken but also the state of the audience.

[0115] In the first embodiment, the traffic jam information acquired via the communication iZF 514 may be used in the determination in step S609 of FIG. Specifically, for example, when passing through a congested part, music content that can be expected to have a relaxed and sedative effect may be determined as the corresponding music content. Example 2
