JP5516124B2 - Content reproduction system and reproduction method according to position information - Google Patents

Description

  The present invention relates to a content playback system and a playback method for playing back appropriate content in conjunction with current location information while moving or at a destination using a mobile information terminal capable of acquiring location information.

  For example, as shown in Patent Document 1, a system that provides information according to the position of a user is known. In this system, a plurality of position information transmission devices are installed in an exhibition hall such as a museum, and each position information transmission device performs infrared communication with a portable terminal that has moved within each infrared reachable range. Provides current location information to the terminal. When acquiring the current position information, the portable terminal requests the server to transmit information (image information or audio information) corresponding to the current position. When the information is received from the server, the received information is provided to the user.

  In this way, using an information terminal capable of acquiring position information as an electronic guidebook, provision of a system and a service for reproducing guide content linked to position information in accordance with the movement of a user is being studied.

No. 11-252121

  In recent years, since information terminals such as mobile phones, smartphones, and PDAs having a function of acquiring position information by a GPS device or the like have become widespread, guides related to exhibits such as museums and art galleries are not used indoors. It is also possible to provide commentary information (guide content) such as facilities and sights at the time of outdoor travel and at the destination as sightseeing information and travel guides.

  As such an outdoor usage form, position-linked contents fixedly linked to position information such as specific facilities and sights are prepared, and depending on the position of the user carrying the information terminal, as appropriate It is conceivable to play the prepared position-linked content. That is, the information terminal downloads the corresponding position-linked content by playing back the position-linked content stored in advance in the information terminal or notifying the current position to the content distribution server according to its current position. To play back.

  Since such location-linked content is linked to a specific location, it is necessary to perform editing such as associating location information and content for each usage region in advance. In addition, since these position-linked contents are linked to a specific position, the user cannot enjoy these contents unless he / she goes to a position corresponding to the position-linked contents.

  The present invention has been made in view of the above-described points. In the position information, the position-linked content can be used without being sent to a specific place, and the information provided by the position-linked content can be received. An object of the present invention is to provide a content reproduction system and a reproduction method according to the content.

In order to solve the above-described problem, a content reproduction system according to claim 1 is provided:
Storage means for storing a plurality of course information including a plurality of contents grouped according to various themes and the timing of providing depends on the position;
A mobile information terminal that can acquire its own location information and can play back content,
The plurality of contents include provision position undetermined contents whose provision timing is not tied to a unique position, and are included in the course information when the user of the mobile information terminal selects desired course information. Provided position determining means for determining a position to be provided based on the position information of the mobile information terminal with respect to content whose position is not yet determined among the plurality of contents,
The mobile information terminal reproduces the corresponding content when it is detected from the position information of the mobile information terminal that a position where any of the plurality of contents included in the course information should be provided is detected. To do.

  In the content reproduction system according to claim 1, as described above, when course information is selected by the user, it is included in the course information in consideration of the position of the mobile information terminal at that time, that is, the position of the user. The provision position to be determined is dynamically associated with the provision position. Accordingly, it is possible to link the content whose provision position is not yet determined at a position where the user can easily visit or a position on the way to the content provision position where the provision position is associated with a unique position. As described above, the provision position of the content included in the course information can be set flexibly, so that the user can receive information on the content included in the course information without going to a specific facility or sight.

  As described in claim 2, the provision position undetermined content has a setting condition for a position to be linked, and the provision position determination means is information necessary for searching for a position satisfying the setting condition. It is preferable to determine the provision position of the provision position undetermined content from the position satisfying the setting condition.

  As a result, the corresponding content can be reproduced from the content of the content whose provision position is undetermined at a position suitable for receiving the provision of the content. For example, when course information in which learning content for learning about a certain theme is grouped as course information is provided, each learning content is used to determine a position to be associated from the content of each content. Setting conditions such as facility name and facility type are given. For example, for course information that groups learning content for learning about "post office structure", the setting conditions for each learning content include the location of a post box, a simple post office, a regular post office (local A setting condition for each learning content is determined so that a branch office, a starting station, and the like) are associated as provision positions. In this case, each learning content describes, for example, the role of the corresponding facility, the service provided there, and the equipment necessary for that purpose.

  According to a third aspect of the present invention, when there are a plurality of candidate positions as positions where the provision position undetermined content is to be provided, the provision position determination means determines which candidate position is the provision position of the provision position undetermined content. May be selected by the user of the mobile information terminal. Thereby, a position convenient for the user can be determined as the content providing position.

  Alternatively, as described in claim 4, when there are a plurality of candidate positions as the position where the provision position undetermined content is to be provided, the provision position determination unit provides a candidate position close to the position of the mobile information terminal. It may be a content provision position. In this case, a position as close to the user as possible can be determined as the content providing position.

  As described in claim 5, based on provision positions of a plurality of contents included in course information, including a provision position of provision position undetermined content determined by provision position determination means, a circulation route around the provision positions It is preferable that the mobile information terminal is provided with a cyclic route set by the cyclic route setting unit. Accordingly, if the user moves along the patrol route, the user can reach the provision position of each content, and can prevent the occurrence of a situation where any content is not provided.

  As described in claim 6, when the order in which a plurality of contents are to be reproduced is predetermined in the course information, the traveling route setting means follows the provision position corresponding to the reproduction order of the plurality of contents. It is desirable to set a patrol route. For example, in the case of the learning content described above, a desirable reproduction order of the content may be determined for reasons such as facilitating understanding.

  As described in claim 7, in the course information, when all the orders for reproducing a plurality of contents are not determined, a desired time for patroling the patrol route by the user of the mobile information terminal When instructed, the tour route setting means preferably sets the tour route so that the required time of the tour route for the provision positions of the plurality of contents included in the course information approaches the desired time. Depending on the contents, there may be no problem even if the order of provision is changed. For example, the theme is “introduction of various occupations”, and a facility corresponding to each occupation is set as a content providing position. In such a case, it is possible to respond as much as possible to the user's desire regarding the traveling time by setting the route for traveling the content provision position in consideration of the desired time for traveling the traveling route.

  On the other hand, as described in claim 8, when the order in which a plurality of contents are to be reproduced is not defined in the course information, a desired time for patroling the patrol route by the user of the mobile information terminal If not instructed, the traveling route setting means sets the traveling route so that the required time of the traveling route around the provision positions of the plurality of contents included in the course information or the distance of the traveling route becomes the shortest. It is preferable to do. Thereby, the user can receive the content included in the course information as much as possible in a short time or a short moving distance.

  As described in claim 9, when the mobile information terminal detects that the mobile information terminal has entered the content playback start area set based on the content provision position based on its own location information, the mobile information terminal starts playback of the content. In addition, when it is detected that the user has exited from the content end area that is set as an area that includes the content playback start area and is wider than the content playback start area, it is preferable to end the playback of the content. As described above, by providing hysteresis in the content reproduction start area and the end area, it is possible to prevent the content reproduction and termination from being repeated.

  Claims 10 to 18 are inventions related to the content reproduction method, but their operational effects are substantially the same as those of the content reproduction system of claims 1 to 9, and thus description thereof is omitted.

It is a block diagram which shows the whole structure of the content reproduction system by this embodiment. It is a conceptual diagram of course information and the position interlocking content contained in the course information. (A) is explanatory drawing for demonstrating the dynamic tied content which determines the provision position dynamically from a user's position etc., and the provision position of a content is not predetermined, (b) It is explanatory drawing for demonstrating the position fixed content by which the provision position of the content was tied beforehand by the specific position. It is a figure which shows the state by which the dynamic tied contents 1-3 included in course information were tied to the position A-position C, respectively using a positional information database. It is a figure which shows an example of the patrol route set so that the provision position of each position interlocking content may be patroled. It is a flowchart which shows the flow of the process for the reproduction | regeneration of a position interlocking | linkage content performed in the mobile information terminal of a content reproduction system. It is a figure which shows the reproduction | regeneration start area | region and reproduction | regeneration end area | region set on the basis of the provision position of each position interlocking content in the reproduction | regeneration processing of a position interlocking content.

  Hereinafter, a content reproduction system according to an embodiment of the present invention will be described with reference to the drawings. The content playback system according to the present embodiment uses a mobile information terminal capable of acquiring position information to play back appropriate content in conjunction with the current position information during movement or at a movement destination. FIG. 1 shows the overall configuration of the content reproduction system according to the present embodiment.

  As shown in FIG. 1, the content reproduction system according to the present embodiment includes a mobile information terminal 10 such as a portable information terminal or an in-vehicle information terminal, a content distribution server 20 and a location information data server 30 that can communicate with the mobile information terminal 10. Consists of

  The mobile information terminal 10 includes a position information acquisition device 11 that can acquire its own position information, such as a GPS device. The position information indicating the position of the mobile information terminal 10 acquired by the position information acquisition apparatus 11 is given to the position-linked content interpretation execution apparatus 14 described later.

  In addition, the mobile information terminal 10 includes a communication device 12 for communicating with the content distribution server 20 and the position information data server 30 described above. The communication between the communication device 12 and the content distribution server 20 and the communication between the communication device 12 and the location information data server 30 will be described in detail later.

  Note that the mobile information terminal 10 does not have to include the position information acquisition unit 11 itself. In this case, the current position of the mobile information terminal 10 may be acquired from the external position information acquisition device 11a via the communication device 12. Specifically, when a user with a portable information terminal moves by car, an example of acquiring the current position of the portable information terminal from a navigation device mounted on the car can be considered.

  In addition, the mobile information terminal 10 includes a content storage medium 13, a position-linked content interpretation execution device 14, an input device 15, and a display / output device 16.

  The content storage medium 13 is for storing position-linked content to be played back by the mobile information terminal 10, the position where the position-linked content is provided, and the like. The position-linked content stored in the content storage medium 13 is distributed from the content distribution server 20 and stored in the content storage medium 13. However, the mobile information terminal 10 may read the position-linked content from the memory card 17 storing the necessary position-linked content and store it in the content storage medium 13.

  The position-linked content interpretation execution device 14 performs data communication necessary for reproducing position-linked content with the content distribution server 20 and the position information data server 30 via the communication device 12. Further, the position-linked content interpretation execution device 14 executes position-linked content reproduction processing. Specifically, it is determined from the position information acquired by the position information acquisition device 11 whether or not the current position of the mobile information terminal 10 has reached a position where the position-linked content should be reproduced. When it is determined that the position where the position-linked content is to be reproduced has been reached, the display / output device 16 is instructed to reproduce the position-linked content stored in the content storage medium 13.

  The display / output device 16 has a display and a speaker, and reproduces and displays moving images, videos, texts, and the like included in the position-linked content and reproduces voice and music according to instructions from the position-linked content interpretation execution device 14. Or something to do.

  The input device 15 has a key and a touch panel, and is used for various inputs by a user. For example, a user of the mobile information terminal 10 must first select course information in order to receive information provided by playing position-linked content. The selection of the course information is also performed using the input device 15. Is called. Furthermore, when there is a desired time for the time required to receive the provision of information on the position-linked content according to the course information, the user can input the desired time using the input device 15.

  The content distribution server 20 includes a database that stores a plurality of course information and a plurality of position-linked contents included in each course information.

  FIG. 2 shows a conceptual diagram of the course information and the position-linked content included in the course information. The course information includes a plurality of position-linked contents that are grouped according to various themes and whose provision timing depends on the position. In the position-linked content, as shown in FIG. 3A, the content provision position is not determined, and the dynamically linked content that dynamically determines the provision position based on the position of the user, etc. As shown in b), there is a position-fixed content in which the content providing position is linked in advance to a unique position. However, the course information includes at least one dynamically linked content.

  Then, in the case of dynamic linking content whose provision position is undetermined, as shown in FIG. 2, it has a linking condition for determining the provision position as part of the data. On the other hand, in the case of position-fixed content in which the provision position is linked to a unique position, information (latitude / lightness information, etc.) indicating the unique position is included as part of the data. In the example illustrated in FIG. 2, the contents 1 to 3 are dynamic linking contents. Furthermore, both the dynamically linked content and the position-fixed content have data to be reproduced on the display / output device 16 such as moving images, videos, narration, and text.

  In addition, there are course information in which the order in which a plurality of position-linked contents are to be reproduced is determined in advance, and course information in which the reproduction order is not determined. As an example of the former, for example, when course information is provided to learn about "post office structure", position-linked content for learning each postal facility so that the flow of mail collection and sorting and delivery can be easily understood. The playback order is determined in advance. On the other hand, as the latter example, for example, the theme is “introduction of various occupations”, and a facility corresponding to each occupation is set as a content providing position. In such a case, since there is little need to order the occupations to be introduced, the reproduction order is not determined. FIG. 2 shows course information in which the order in which a plurality of position-linked contents are to be reproduced is determined.

  Here, a procedure of communication performed between the mobile information terminal 10 and the content distribution server 20 and data to be communicated will be described. Note that when the mobile information terminal 10 communicates with the content distribution server 20 and downloads position-linked content or the like, the content distribution server may distribute the position-linked content for free, or charge processing as paid distribution. You can go.

  For example, the content distribution server 20 first distributes various course information to the mobile information terminal 10 in response to a request from the user of the mobile information terminal 10. Then, the desired course information is selected by the user of the mobile information terminal 10, and the selection result is transmitted to the content distribution server 20. When the user of the mobile information terminal 10 determines desired course information in advance, the desired course information is transmitted directly to the content distribution server 20 without downloading various course information from the content distribution server 20. Also good.

  When the course information is transmitted from the mobile information terminal 10, the content distribution server 20 transmits the position-linked content included in the course information to the target mobile information terminal 10. In this case, the content distribution server 20 may transmit all the position-linked content data included in the course information in a batch. Moreover, according to the position of the mobile information terminal 10, the data of a position interlocking | linkage content may be transmitted separately at the appropriate timing before reaching the provision position of each content.

  However, even if the data of location-linked content is sent individually, the data indicating the binding conditions of the dynamically linked content and the position where the fixed location content is provided is selected when the course information is selected by the user. To the mobile information terminal 10. As will be described later, this determines the provision position of the dynamic linking content, and circulates each provision position based on the determined provision position of the dynamic linking content and the provision position of the fixed position content. This is for setting a traveling route to be presented and presenting it to the user of the mobile information terminal 10. The set tour route is presented to the user using the display / output device 16.

  The location information data server 30 has a location information database that stores information such as name, type, location information (latitude, longitude, and address) associated with each other for various facilities and sights. A procedure of communication performed between the location information data server 30 and the mobile information terminal 10 and data to be communicated will be described below.

  When the mobile information terminal 10 acquires the position-linked content data (or the dynamic link content link conditions and the position fix content provision position data) included in the selected course information, the mobile information terminal 10 uses the position information acquisition device 11. The acquired positional information, the dynamic linking content linking conditions, and the position where the fixed position content is provided are transmitted to the position information data server 30.

  In the position information data server 30, first, based on the current position of the mobile information terminal 10 indicated by the received position information and the link condition of the dynamic link content, the position (dynamic The location information database) is searched for in the location information database. Specifically, it is possible to define a search range based on the current position of the mobile information terminal 10, and to match the dynamic linking content in the search range and match the dynamic linking content. Search for the correct position. However, when the position information is included in the course information, it is preferable to search for a position that can be linked in consideration of the position where the position fixing content is provided. Specifically, the search range is set to a range that includes both the current position of the mobile information terminal 10 and the position where the fixed content is provided, or between the current position of the mobile information terminal 10 and the position where the fixed content is provided. Or set to the range. The search range may be enlarged or reduced according to the desired time when the user inputs a desired time related to the required time when selecting the course information.

  When a plurality of positions that can be associated with one dynamic association content are searched in the search range, the search results (a plurality of candidate positions) are transmitted to the mobile information terminal 10. Then, the mobile information terminal 10 presents a plurality of candidate positions and causes the user to select any position. In this case, when the user selects any position, the selected position is transmitted to the position information data server 30. On the other hand, when the user makes an answer that the selection of the position is left to the system, the answer result is transmitted to the position information data server 30. Note that it may be possible to set in advance that the user entrusts position selection to the system, and transmission of a plurality of candidate positions to the mobile information terminal 10 may be omitted.

  When the position information data server 30 obtains an answer from the user that the selection from a plurality of candidate positions is entrusted, the position information data server 30 selects a position close to the current position of the mobile information terminal 10 from the plurality of candidate positions, It is determined as the provision location of attached content.

  FIG. 4 shows a state in which the dynamic association contents 1 to 3 included in the course information shown in FIG. 2 are associated with the positions A to C using the position information database.

  Then, the location information data server 30 sets a patrol route that circulates the provision position of the dynamically linked content and the provision position of the fixed position content. This patrol route is set using the map data that the position information data server 30 has. In this way, by setting a patrol route that goes around the provision positions of all the position-linked contents included in the course information, the user can reach the provision position of each position-linked content as long as the user moves along the patrol route. At the same time, it is possible to prevent a situation in which any position-linked content is not provided.

  Hereinafter, a method for setting a patrol route will be described in detail.

  First, in the course information, when the order in which a plurality of position-linked contents are to be reproduced is determined in advance, the position information data server 30 follows the provided position corresponding to the reproduction order of the plurality of position-linked contents. Set the patrol route.

  On the other hand, in the course information, when not all orders in which a plurality of position-linked contents are to be reproduced (including cases where the reproduction order is set for some position-linked contents), use of the mobile information terminal 10 is used. Depending on whether or not the desired time for patroling the patrol route is instructed by the user, the patrol route setting method differs.

  First, when the user of mobile information terminal 10 is instructed by the user of the desired time for visiting the tour route, the location information data server 30 visits the tour route for providing a plurality of location-linked content provided in the course information. The traveling route is set so that the required time of the vehicle approaches the desired time. Specifically, the required time of the route between two provision positions that are relatively close to each other is calculated based on the map data for each provision position. Then, while visiting all the provided positions, a combination of routes that makes the overall required time closest to the user's desired time is obtained, and this is set as a circulating route. Thereby, it is possible to respond as much as possible to the user's desire regarding the traveling time.

  If the playback order is determined for some position-linked content, the route connecting the position-linked content providing positions for which the playback order is determined is fixed, while the routes related to other provided positions are changed, Find the best combination of routes.

  On the other hand, when the user of the mobile information terminal 10 has not instructed the desired time for patroling the patrol route, the location information data server 30 circulates the provision positions of a plurality of location-linked contents included in the course information. The traveling route is set so that the required time of the traveling route is the shortest or the distance of the traveling route is the shortest. As a result, the user can receive the position-linked content included in the course information as much as possible in a short time or a short moving distance.

  FIG. 5 shows an example of the set cyclic route. When the patrol route is set in this way, the data necessary for displaying the patrol route on the map data and presenting it to the user at the mobile information terminal 10 is moved together with the position where the dynamically linked content is provided. It transmits to the information terminal 10. In this case, if the mobile information terminal 10 has map data, only route data indicating a patrol route may be transmitted. On the other hand, if the mobile information terminal 10 does not have map data, it transmits route data indicating a patrol route and map data covering the route data.

  In the above-described embodiment, the position information data server 30 determines the provision position of the dynamically associated content, and sets a circulation route that circulates the provision position of the dynamically associated content and the fixed position content. However, the mobile information terminal 10 may determine the provision position of the dynamically linked content and set the tour route with reference to the position information database. Furthermore, it is possible to provide the mobile information terminal 10 with a location information database and map data. In this case, communication with the position information data server 30 can be made unnecessary.

  In the above-described embodiment, the example in which the content distribution server 20 and the position information data server 30 are provided separately has been described. However, one server may have both functions of the content distribution server 20 and the position information data server 30. Is possible. In this case, if the mobile information terminal 10 transmits the desired course information and the current position information, the server side can determine the provision position of the dynamically linked content and set the tour route. is there.

  Next, a flow of processing for reproducing position-linked content executed in the mobile information terminal 10 of the content reproduction system according to the present embodiment will be described based on the flowchart of FIG.

  First, in step S100, it is determined whether or not course information is selected in the mobile information terminal 10, and if it is not selected, the process waits until course information is selected. When the course information is selected, the position-linked content included in the selected course information is read in the subsequent step S110. In this case, it is possible to read only the linking condition of the dynamically linked content and the provision position of the fixed position content.

  In step S <b> 120, the position information acquisition device 11 acquires position information indicating the current position of the mobile information terminal 10. In step S130, the current position of the mobile information terminal 10, the link condition of the dynamically linked content read in step S110, and the provision position of the fixed position content are transmitted to the position information data server. Then, in the position information data server, a position suitable for playing back the dynamically linked content based on the current position of the mobile information terminal 10, the linked condition of the dynamically linked content, and the provision position of the fixed position content. Searched. However, when a plurality of candidate positions are searched, there is an inquiry from the position information data server 30 as to which of the plurality of candidate positions should be the provision position of the dynamically linked content. If there is an inquiry, “Yes” is determined in step S140, and the process proceeds to step S150. On the other hand, if there is no inquiry, the process proceeds to step S180.

  In step S150, it is determined whether any of a plurality of candidate positions has been selected by the user. If it is determined that the user has selected, the selection result is transmitted to the location information data server 30 in step S160. On the other hand, if the user does not make a selection and entrusts the selection to the system, the process proceeds to step S170, and a response to that effect is transmitted to the location information data server 30.

  Thereby, in the position information data server 30, the provision position of the dynamically associated content is determined, and the circulation route for circulating the provision position of the dynamically associated content and the fixed position content is set.

  In step S180, data related to the set patrol route is received together with the provision position of the dynamically linked content. In step S190, the mobile information terminal 10 presents the tour route and starts the position-linked content reproduction process.

  In the position-linked content reproduction process, as shown in FIG. 7, the reproduction start area and the reproduction end area are determined based on the position where each position-linked content is provided. The playback end area includes a playback start area and is set as an area wider than the playback start area.

  Then, when the mobile information terminal 10 detects that it has entered the reproduction start area of any position-linked content based on the position information acquired by the position information acquisition unit 11, it starts playing the corresponding position-linked content. . Furthermore, when the mobile information terminal 10 detects that the mobile information terminal 10 has left the playback end area, the mobile information terminal 10 ends the playback of the corresponding position-linked content. Thus, by providing hysteresis in the playback start area and the playback end area of the position-linked content, it is possible to suppress repeated playback and termination of the position-linked content.

  As described above, according to the content reproduction system according to the present embodiment, when the user selects course information, the current position of the mobile information terminal 10 at that time, that is, the current position of the user is taken into consideration. The dynamic association content included in the course information is dynamically associated with an appropriate provision position. Accordingly, the provision position of the dynamically linked content is linked to the position where the user can easily visit or the position where the provision position is linked to the unique position of the position fixed content. It becomes possible. In this way, the location of content-linked content included in the course information can be set flexibly, so that the user can receive information on the location-linked content included in the course information without going to a specific facility or sight. Can do.

  Furthermore, in the content reproduction system according to the present embodiment, the dynamic linking content has a setting condition for the position to be linked as a part of the data, and the dynamic linking content is located at a position that satisfies the setting condition. Attached content is linked. As a result, the dynamic linked content can be reproduced from the content of the dynamic linked content at a position suitable for receiving the provision of the dynamic linked content.

  For example, for course information that groups learning content for learning about "post office structure", the setting conditions for each learning content include the location of a post box, a simple post office, a regular post office (local A setting condition for each learning content is determined so that a branch office, a starting station, and the like) are associated as provision positions. In this case, each learning content describes the role of the corresponding facility, the service provided there, and the facilities necessary for that purpose.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the course information is a group of learning contents for learning about a certain theme. However, the course information is not limited thereto, and can be applied as a sightseeing guide or a travel guide. In this case, the content playback system according to the present embodiment can play back dynamically linked content that is not linked to a specific point in advance, so that the content related to the tourist spot even when moving from home to a tourist spot In addition, various contents such as entertainment contents can be presented regardless of the departure place.

  As course information, course information including position-linked experience game content can be set. For example, when performing a drive date, by describing the contents related to the stop date spot as dynamic linked contents, it is possible to provide course information that can be enjoyed anywhere regardless of the position of the user.

  Further, in the above-described embodiment, when the priority order is given to the position-linked content included in the course information, and the user has designated the desired time for visiting the position for providing the position-linked content, all the contents are specified. In the case where the tour time when the tour location is visited is longer than the desired time by a predetermined time, provision of low priority content may be omitted so that the tour time is within the desired time.

  In addition, important content that is always played back and optional content that is played back as necessary are provided in each content itself, and only important content is provided when the content provision time interval is short depending on the circulation route. When content is reproduced and the provision time interval becomes long, optional content may also be reproduced.
