  Here, in the learning system as described above, terms or the like that the user does not know may be used in the reproduced moving image or audio, and when such terms appear during learning, the user In order to understand the meaning of terms and the like, it is often examined using a dictionary or the like. However, the conventional technology as described above has a problem that convenience in performing a search using a dictionary or the like is not considered.

  That is, in recent years, the price of storage devices such as hard disks has decreased, and it has become easier to store a plurality of dictionaries in a terminal device. When a plurality of dictionaries are stored, it is necessary for the user to select a dictionary to be used for search from the plurality of dictionaries. Such selection becomes more troublesome and complicated for the user as the number of selection target dictionaries increases.

  However, Patent Documents 1 and 2 that do not assume that a search by a dictionary is performed during content reproduction do not describe any configuration for facilitating the user's selection of a dictionary.

  Note that such a problem is not limited to the terminal device used in the learning system, and is a problem that occurs in all content playback devices that play back content such as moving images, still images, or audio. This is because performing a search related to the content using an arbitrary database during the reproduction of the content is not limited to the learning content and exists.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a content reproduction apparatus and the like that allow a user to easily perform a search using a desired database.

  In order to solve the above-described problem, the content playback apparatus of the present invention is a content playback apparatus that plays back content, and refers to priority data in which priorities are set for each of a plurality of databases. An object display means for displaying an object corresponding to a high database in priority during the reproduction of content over an object corresponding to a database having a low priority, and when the object displayed by the object display means is selected, the object And a search means for performing a search using a database corresponding to.

  The content playback apparatus control method according to the present invention is a content playback apparatus control method for playing back content in order to solve the above-described problem, and includes priority data in which priorities are set for each of a plurality of databases. The object display step for displaying an object corresponding to a database with a high priority during content playback in preference to an object corresponding to a database with a low priority, and the object displayed in the object display step are A search step of performing a search using a database corresponding to the object when selected.

  According to said structure, with reference to priority data, the object corresponding to a database with high priority is displayed preferentially over the object corresponding to a database with low priority. When the displayed object is selected, a search is performed using a database corresponding to the object.

  Therefore, the user can easily select an object corresponding to a database in which high priority is set in the priority data, and cause the content reproduction apparatus to execute a search using the database.

  That is, according to the above configuration, by setting a high priority to a database that is highly likely to be selected by the user, the user can easily perform a search using a desired database.

  Note that displaying an object preferentially means displaying the object so that the user can easily confirm and select the object over other objects.

  In order to solve the above problems, the content reproduction apparatus of the present invention is a content reproduction apparatus that reproduces content, the attribute specifying means for specifying the attribute of the content being reproduced by the own device, By referring to the correspondence information associated with the database, the object corresponding to the database associated with the attribute identified by the attribute identification unit is more than the object corresponding to the database not associated with the attribute. Object display means for displaying content during priority reproduction, and search means for performing a search using a database corresponding to the object displayed by the object display means when selected. It is a feature.

  In order to solve the above problems, the content playback device control method of the present invention is a content playback device control method for playing back content, and specifies an attribute of content being played back by the content playback device. With reference to the correspondence information in which the attribute identification step and the attribute and the database are associated, the object corresponding to the database associated with the attribute identified by the attribute identification unit is associated with the attribute. An object display step that is displayed during content playback in preference to an object corresponding to an unsupported database, and a search that uses the database corresponding to the object when the object displayed in the object display step is selected And a step.

  According to said structure, the object corresponding to the database matched with the attribute of the content which the content reproduction apparatus is reproducing | regenerating is displayed preferentially. Therefore, the user can easily select an object corresponding to the database associated with the attribute of the content being reproduced and perform a search using the database.

  Therefore, according to the above configuration, a user can search a desired database by using correspondence information associated with the attribute of a database that is highly likely to be selected by the user according to the attribute of the content. Can be made easier.

  Further, the content reproduction apparatus refers to usage history data in which a plurality of the databases and frequency information indicating the frequency of the search using the databases are associated with each other. It is preferable to provide priority data generation means for generating the priority data in which higher priority is set for a higher database.

  According to the above configuration, referring to the usage history data in which the database and the frequency information indicating the frequency of the search using the database are associated with each other, the database with the higher frequency of the search is higher. Priority data with priority set is generated.

  Here, it can be said that a database that is frequently searched is a database that is highly likely to be selected by the user. Therefore, according to said structure, it can make it easy for a user to search by a desired database.

  The content reproduction apparatus preferably includes usage history data generation means for generating the usage history data by counting the number of times the search means performs a search for each of the plurality of databases.

  According to the above configuration, the usage history data is generated by counting the number of searches for each database. That is, in the above configuration, the counted number of searches is used as frequency information. As a result, the object is displayed based on the usage history data reflecting the number of searches performed by the content reproduction apparatus.

  Since a database having a high number of uses is highly likely to be selected by the user, according to the above configuration, the user can easily perform a search using a desired database.

  The usage history data generating means transmits the generated usage history data to a totaling device that counts usage history data, and the priority data generating means includes the usage history data generating means and the usage history data generating means. For the usage history data received from other devices, obtain the integrated usage history data obtained by summing the number of searches included in each usage history data for each of the plurality of databases from the aggregation device, and refer to the integrated usage history data Thus, it is preferable to generate the priority data.

  According to said structure, based on the priority data produced | generated with reference to the integrated usage history data which totaled the usage history data received from the content reproduction apparatus and other apparatuses, an object is displayed. Since the integrated usage history data also reflects the number of searches performed by the content reproduction apparatus, the user can easily select a database that the user frequently uses.

  In addition, since the integrated use history data also reflects the number of searches performed by other devices, objects corresponding to databases frequently used by users of other devices are also displayed preferentially. For this reason, it is possible to recognize what kind of database is being used by users of other devices, and it is also possible to easily select a database that is frequently used by other users.

  The content playback device includes attribute specifying means for specifying an attribute of the content being played back by the device itself, and the object display means refers to correspondence information in which the attribute is associated with the database. Preferably, the object corresponding to the database associated with the attribute identified by the attribute identifying means is displayed with priority over the object corresponding to the database not associated with the attribute.

  According to said structure, the object corresponding to the database matched with the attribute of the content which the content reproduction apparatus is reproducing | regenerating is displayed preferentially. Therefore, the user can easily select an object corresponding to the database corresponding to the attribute of the content being reproduced and perform a search using the database.

  In other words, according to the above configuration, a user can search a desired database by using correspondence information associated with the attribute of a database that is highly likely to be selected by the user according to the attribute of the content. Can be made easier.

  In addition, the content reproduction apparatus stores history data in which position information indicating a reproduction position of the content when the search unit performs a search and access information for accessing a search result by the search unit are associated with each other. Generating history data generating means, wherein the usage history data generating means refers to the history data generated by the history data generating means to determine the number of times the search means has performed a search for each of the plurality of databases. Preferably, the usage history data is generated by counting.

  According to said structure, the log | history data which matched the positional information which shows the reproduction | regeneration position of the content at the time of searching, the said keyword used for search, and the access information for accessing a search result are produced | generated. .

  By using the history data, when the content is reproduced, the search result can be accessed at the reproduction position where the search has been performed in the past. Therefore, when the content is played back for the second time or later, it is possible to easily access the result of the past search.

  Since the history data includes position information and access information, the number of searches and the database used for the search can be specified from the history data. Therefore, according to the above configuration, the use history data is generated using the history data.

  This makes it possible to generate usage history data without providing a separate configuration for acquiring the database used for the search and the number of searches.

  Further, the search means performs a search in a database corresponding to the selected object using a keyword input to the device, and the history data generation means includes the keyword used by the search means for the search. When the history data is generated and the device is reproducing the content, the playback position of the content matches the playback position indicated by the position information included in the history data generated by the history data generation means When the keyword displayed in the history data is displayed so that the keyword associated with the position information can be selected by the user of the device, and the keyword displayed by the keyword display processing unit is selected, the history is displayed. The search obtained using the access information associated with the selected keyword in the data It is preferable that a search result display means for displaying the results.

  According to the above configuration, when the reproduction position of the content matches the reproduction position indicated by the position information included in the history data, the keyword associated with the position information is displayed. As a result, the user can recognize that a search was previously performed using the keyword.

  And according to said structure, when the displayed keyword is selected, the search result acquired using the access information matched with the keyword is displayed. That is, when the user wants to confirm the search result by the displayed keyword again, the user can receive the search result by an extremely simple operation of selecting the displayed keyword. Further, when it is determined that there is no need to reconfirm the search result based on the displayed keyword, the user can continue viewing the content as it is.

  Note that the retrieval result acquisition method depends on what information is the access information. For example, when the access information is information for specifying a database searched by a keyword, the search result can be acquired by performing a search again using the database using the keyword. For example, when the access information is information (address or the like) indicating the storage location of the search result, the search result can be acquired from the storage location specified by the information.

  The function of the search result display means can also be realized by the search means. That is, the search means may acquire the search result using the access information.

  The history data generating means preferably generates history data including the keyword used for the search by the search means as the access information.

  When the history data including the keyword used for the search is generated as in the above configuration, the search result can be accessed by searching the database using the keyword included in the history data.

  In addition, the content reproduction apparatus is configured to delete history data corresponding to a keyword when the keyword display processing unit displays the keyword or when the search result display unit displays the search result. It is preferable to include a history data deleting means for displaying the deletion object so that the user can select it.

  According to the above configuration, the deletion object for deleting the history data corresponding to the keyword is displayed. Therefore, the user can select the deletion object and delete the history data corresponding to the keyword so that the keyword is not displayed when the content is reproduced next time. This is useful, for example, when the user has already stored the search result based on the keyword.

  The content reproduction apparatus may be realized by a computer. In this case, a control program for realizing the content reproduction apparatus by a computer by causing the computer to operate as each unit of the content reproduction apparatus, and A computer-readable recording medium on which it is recorded also falls within the scope of the present invention.

  As described above, the content playback apparatus of the present invention refers to the priority data in which the priority is set for each of the plurality of databases, and converts the object corresponding to the database with the higher priority to the database with the lower priority. Object display means for displaying during content reproduction with priority over the corresponding object, and search means for performing a search using a database corresponding to the object when the object displayed by the object display means is selected. It is the composition which is provided.

  In addition, as described above, the content playback apparatus control method of the present invention refers to priority data in which priorities are set for each of a plurality of databases, and prioritizes objects corresponding to databases with high priorities. An object display step that is displayed during content playback in preference to an object corresponding to a database having a low degree, and when an object displayed in the object display step is selected, a search is performed using the database corresponding to the object. And a search step to be performed.

  As described above, the other content reproduction apparatus of the present invention refers to attribute identification means for identifying the attribute of the content being reproduced by the apparatus, and correspondence information in which the attribute and the database are associated with each other. Thus, an object corresponding to a database that is a target to be searched when the device is reproducing content and that is associated with the attribute specified by the attribute specifying unit is associated with the attribute. It is configured to include object display means for display so that the user of the own apparatus can select it in preference to the object corresponding to the database that is not provided.

  In addition, as described above, another control method of the content playback apparatus according to the present invention includes an attribute specifying step for specifying an attribute of the content being played back by the content playback apparatus, and a correspondence between the attribute and the database. An object corresponding to a database that is a target to be searched when the device is reproducing content with reference to the information and that is associated with the attribute identified in the attribute identifying step is And an object display step in which the user of the own apparatus displays the object in a selectable manner in preference to the object corresponding to the database not associated with the attribute.

  According to each of the above configurations, the object corresponding to the database that is likely to be selected by the user is preferentially displayed, so that the user can easily perform a search using the desired database.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. Here, first, the configuration of the electronic learning apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a main configuration of an electronic learning device (content reproduction device) 1.

  The electronic learning device 1 is a device that reproduces content, and includes an input unit 10, a display unit 11 that displays an image, a control unit 12, and a storage unit 13, as illustrated.

  The input unit 10 receives user input operations, and the user controls the operation of the electronic learning apparatus 1 via the input unit 10. Here, it is assumed that the input unit 10 is a so-called touch panel that detects an input operation on the display surface of the display unit 11 and receives the detected input operation. Of course, the input unit 10 only needs to be able to accept a user's input operation, and may be configured with an input key, a keyboard, or the like. Here, an example in which the electronic learning device 1 includes the input unit 10 is shown, but the input unit 10 may be a device separate from the electronic learning device 1.

  The display unit 11 displays an image according to the control of the control unit 12. For example, a liquid crystal display device, an EL display device, or the like can be applied as the display unit 11. Similarly to the input unit 10, the display unit 11 may be a separate device from the electronic learning device 1.

  The control unit 12 controls the operation of the electronic learning apparatus 1 in an integrated manner, and includes a reproduction processing unit 20, a search processing unit (search unit, search result display unit) 21, a history data generation unit (history data generation unit, History data deleting means) 22, keyword display processing section (keyword display processing means) 23, dictionary display order determining section (priority data generating means, usage history data generating means) 24, content type determining section (attribute specifying means) 25, And a dictionary key display processing unit (object display means) 26.

  The reproduction processing unit 20 performs processing for reproducing content. Specifically, the reproduction processing unit 20 reads content corresponding to the content of the input operation received by the input unit 10 from the storage unit 13 and causes the display unit 11 to display the content. Here, it is assumed that the playback processing unit 20 plays back moving image content. However, the playback processing unit 20 may perform slideshow display of content made up of still images or play back content made up of audio. . When the content to be reproduced includes sound, the reproduction processing unit 20 outputs the sound of the content from a speaker (not shown).

  The search processing unit 21 displays, as a search result, an image based on data detected by performing a database search with a keyword input when the reproduction processing unit 20 is reproducing content. Specifically, the search processing unit 21 displays a keyword input screen for inputting a keyword on the display unit 11. Then, the database is searched using the keyword accepted by the input unit 10 during display of the keyword input screen, and the search result is displayed on the display unit 11. Here, it is assumed that the database to be searched is dictionary data stored in the storage unit 13.

  The history data generation unit 22 generates history data indicating a history of keyword search. Specifically, the history data generation unit 22 accesses position information indicating the reproduction position of the content (reproduction position from the beginning of the content) when the keyword search is performed, and access for accessing the search result by the keyword. The history data is generated in association with the information and stored in the storage unit 13. The history data generation unit 22 associates the history data with the keyword used for the search in addition to the position information and the access information.

  Here, it is assumed that the reproduction time of the content is used as the position information, and a dictionary ID indicating a database to be searched and a keyword ID indicating a keyword used for the search are used as the access information. ing.

  Of course, the position information is not limited to this example as long as it indicates the reproduction position of the content when the keyword search is performed. The access information is not limited to this example as long as it is information that can access the search result. For example, information specifying a keyword and information specifying a dictionary may be used as access information.

  The keyword display processing unit 23 displays the keyword used for the search on the display unit 11 at the timing when the keyword search was performed in the past during the reproduction of the content. Specifically, the keyword display processing unit 23 refers to the history data stored in the history data generation unit 22 and identifies the timing at which the keyword search was performed in the past and the keyword used for the search. Is displayed.

  Further, when the displayed keyword is selected, the keyword display processing unit 23 acquires a search result based on the keyword using the access information of the history data and displays it. Specifically, when the displayed keyword is selected, the keyword display processing unit 23 notifies the search processing unit 21 of the selected keyword and a database that has been searched using the keyword, and performs keyword search. Let it be done and display the results.

  The dictionary display order determination unit 24 determines the order in which the dictionary used by the search processing unit 21 for search is presented to the user of the device itself. Specifically, the dictionary display order determination unit 24 generates / updates usage history total data indicating the usage history of the dictionary, and uses the usage history total data to define dictionary display order data that defines the display priority of the dictionary. Is generated. Details of the usage history tabulation data and the dictionary display order data will be described later.

  The content type determination unit 25 determines the type of content being played back by the playback processing unit 20 and notifies the dictionary key display processing unit 26 of the determination result. Note that the content type refers to an attribute of a content serving as a reference for determining what dictionary should be presented to the user during the reproduction of the content.

  Specifically, it is assumed here that the subject to which the content belongs is set as the content type. This is because if the subject is known, the dictionary to be presented during the reproduction of the content can be specified to some extent. Of course, the content type determined by the content type determination unit 25 is not limited to this example as long as it is an attribute of the content that can specify to some extent a dictionary to be presented during the reproduction of the content.

  The dictionary key display processing unit 26 determines a dictionary to be assigned to the dictionary key according to the content type determined by the content type determination unit 25. Then, the dictionary key display processing unit 26 displays the dictionary keys (objects) in the display order determined by the dictionary display order determining unit 24.

  Specifically, the dictionary key display processing unit 26 specifies a dictionary corresponding to the content type determined by the content type determination unit 25 using the type-dictionary correspondence data in which the content type and the dictionary are associated with each other. Then, dictionary keys corresponding to these dictionaries are preferentially presented to the user. Further, referring to the dictionary display order data generated by the dictionary display order determination unit 24, the dictionary key corresponding to the dictionary having the higher display order is displayed with priority over the dictionary key corresponding to the dictionary having the lower display order.

  The storage unit 13 stores various data used by the electronic learning apparatus 1, and includes moving image data (content) 30, dictionary data (database) 31, history data 32, usage history total data (use history data) 33, Dictionary display order data (priority data) 34 and type-dictionary correspondence data (correspondence information) 35 are included.

  The moving image data 30 is moving image data of content to be reproduced by the reproduction processing unit 20. That is, the reproduction processing unit 20 reads and reproduces the moving image data 30. Here, an example in which the moving image data 30 is stored in the storage unit 13 will be described. However, the moving image data 30 only needs to be stored so that the reproduction processing unit 20 can reproduce it. It may be stored in a connected external storage device. For example, it may be stored in a device such as a server that is communicably connected to the electronic learning device 1. In this case, the moving image data 30 may be downloaded to the electronic learning device 1 and played back, or streaming playback may be performed without downloading.

  The dictionary data 31 is a database used by the search processing unit 21 for keyword search. Here, it is assumed that a database of a plurality of dictionaries such as an English-Japanese dictionary or a Japanese dictionary is stored as the dictionary data 31. In these databases, headwords (words to be searched for keywords) are associated with data indicating their meanings, etc., and search is performed with keywords that match the headwords, so that the headwords are supported. It is possible to access data indicating the meaning or the like of the attached headword.

  As described above, the history data 32 is data generated and stored by the history data generation unit 22, and the access time for accessing the content reproduction time when the keyword search is performed and the search result by the keyword. Data associated with information.

  The usage history total data 33 indicates the usage history of the dictionary. Here, it is assumed that the usage frequency of each dictionary is specified using the usage history total data 33, and the display order of the dictionary is determined based on this usage frequency. For this reason, the usage history total data 33 only needs to include frequency information indicating the usage frequency of each dictionary.

  The dictionary display order data 34 is data indicating the display order of the dictionary. As described above, the dictionary display order data 34 is generated based on the usage history total data 33. Specifically, the dictionary display order data 34 is generated such that the dictionary having a higher count number in the usage history total data 33 has a higher numerical value in the order.

  The dictionary display order is determined with reference to the dictionary display order data 34. For this reason, the dictionary display order data 34 can also be expressed as priority data in which the priority for presenting each dictionary to the user is set.

  The type-dictionary correspondence data 35 is data in which a content type and a dictionary are associated with each other. As described above, referring to the type-dictionary correspondence data 35, a dictionary corresponding to the type of content being reproduced is specified.

[History data 32]
The history data 32 may be data as shown in FIG. FIG. 2 is a diagram illustrating an example of the history data 32. The illustrated history data 32 is generated for the content “training video 1-1”, and is associated with a number, a reproduction time, a used dictionary, a keyword, a dictionary ID, and a keyword ID. It is data.

  The number is a number for managing a combination of a reproduction time, a use dictionary, and a keyword included in the history data 32. This number is assigned when the history data generation unit 22 stores the reproduction time, the used dictionary, and the keyword.

  The reproduction time indicates the reproduction time of the content when the keyword search is performed. As for the reproduction time, the history data generation unit 22 acquires and stores the reproduction time of the content when the keyword search is performed.

  The use dictionary indicates a dictionary used for keyword search. The usage dictionary is stored by specifying the dictionary used by the history data generation unit 22 for keyword search.

  The keyword indicates a keyword used for keyword search. The keyword is acquired and stored by the history data generation unit 22 when a keyword search is performed.

  The dictionary ID specifies the dictionary used for keyword search, and the keyword ID specifies the position where the keyword is stored in the dictionary used for search. That is, here, it is assumed that a keyword ID is assigned in advance to a headword (word to be searched for a keyword) included in each dictionary. Then, it is assumed that when a keyword search is performed and the keyword used in the search matches the headword, history data 32 including the keyword ID assigned to the headword is generated.

  According to this configuration, each headword included in the dictionary is matched with the keyword, and the storage position of the headword that matches the keyword is specified without performing the process of searching for the headword that matches the keyword. The data indicating the meaning of the headword, that is, the search result can be accessed. Therefore, it is possible to shorten the time until the search result by the keyword is reached as compared with the case of performing the search again by the keyword.

  By using such history data 32, when the “training video 1-1” is reproduced, the keyword used for the keyword search can be displayed at the timing when the keyword search was performed in the past. When the displayed keyword is selected, the search by the keyword can be executed again and the search result can be displayed.

  The history data 32 may be a keyword that can be displayed at the timing when a keyword search has been performed in the past, and when the displayed keyword is selected, a search result based on the keyword can be displayed. Well, it is not limited to the example of FIG.

  That is, in the example of FIG. 2, an example in which the dictionary ID and the keyword ID are included in the history data 32 as information for accessing the search result by the keyword is shown. However, the history data 32 only needs to include position information indicating the reproduction position when the search is performed and access information for accessing the search result, and is not limited to the above example. For example, the access information may include only information indicating a keyword and a used dictionary, or may include information (address or the like) indicating a storage position of a search result.

[About usage history data 33]
The usage history total data 33 may be as shown in FIG. FIG. 3 is a diagram illustrating an example of the usage history summary data 33. The illustrated usage history tabulated data 33 is data in which a dictionary ID and a count number are associated with each other. That is, the usage history tabulated data 33 shown in the figure is a counter that counts the number of times each dictionary is used.

  By using such usage history tabulation data 33, it is possible to identify which dictionary is used frequently, so that a dictionary with high usage frequency is given priority to a user with low usage frequency. Can be presented.

  The usage history total data 33 is not limited to the example shown in the drawing as long as the information specifying each dictionary is associated with information indicating the usage frequency of the dictionary. For example, a dictionary name may be stored instead of the dictionary ID. Further, for example, information indicating the level of use frequency such as “high”, “medium”, and “low” may be stored instead of the number of times of use.

  Here, it is assumed that the usage history total data 33 is generated using the history data 32. Specifically, for each “dictionary ID” included in the history data 32, the number of cases where “reproduction time” is recorded is counted, and the dictionary ID is associated with the counted number as shown in FIG. Usage history total data 33 is generated.

[About dictionary display order data 34]
The dictionary display order data 34 may be as shown in FIG. FIG. 4 is a diagram illustrating an example of the dictionary display order data 34. The illustrated dictionary display order data 34 is data in which a numerical value indicating the display order (priority) of a dictionary is associated with a dictionary name.

  That is, in the illustrated example, it is assumed that the dictionary is presented (assigned to the dictionary key) in ascending order of the numerical value indicating the display order. The dictionary display order data 34 is not limited to the example shown in the drawing as long as it can specify the display order of each dictionary. For example, information for specifying a dictionary such as a dictionary ID may be associated instead of the dictionary name.

  Here, it is assumed that the dictionary display order determination unit 24 generates the dictionary display order data 34 using the usage history tabulation data 33, but the electronic learning device 1 has never been searched. Therefore, the dictionary display order data 34 may be stored in the storage unit 13 in advance.

  Further, the value of the dictionary display order data 34 may be set / changed by a user operation. Thereby, it is also possible to present the dictionary in the display order desired by the user.

[About Type-Dictionary Data 35]
The type-dictionary correspondence data 35 may be as shown in FIG. FIG. 5 is a diagram illustrating an example of the type-dictionary correspondence data 35. The illustrated type-dictionary correspondence data 35 is data in which a content type and a dictionary name are associated with each other.

  In the illustrated example, “national language”, “English”, and “society” are included as types. In other words, it is assumed here that “subject” is the type of content. Each subject is associated with a dictionary frequently used in the subject.

  Specifically, “Japanese language dictionary K”, “Japanese language dictionary D”, and “Japanese language dictionary M” are associated with “national language”. In addition, “English” is associated with “English-Japanese Dictionary G”, “English-Japanese Dictionary P”, and “English-English Dictionary O”. “Society” is associated with “person encyclopedia A”, “map B”, and “map C”. These dictionaries and encyclopedias are stored in the storage unit 13 as dictionary data 31. The same applies to the map. The map database is a database for performing a search using a place name or the like as a keyword and presenting a map including the place name or the like as a search result.

  By using this type-dictionary correspondence data 35, a dictionary or the like corresponding to the type of content being reproduced can be specified. For example, when the content being reproduced is “National Language” content, it is possible to specify that the dictionary to be displayed is “National Language Dictionary K”, “National Language Dictionary D”, and “National Language Dictionary M”. .

  In the illustrated example, a number is associated with each dictionary. This number is a number for managing a dictionary associated with each subject.

[Operation Example of Electronic Learning Device 1 (Generation and Recording of History Data)]
Next, an operation example of the electronic learning device 1 will be described with reference to FIG. FIG. 6 is a diagram showing an example of the operation of the electronic learning device 1. FIG. 6A shows a pre-dictionary selection, FIG. 6B shows a keyword search using the selected dictionary, and FIG. An example of operation after execution of a search is shown.

  In the example of FIG. 5A, an image of content is displayed in the image display area A1. Here, it is assumed that content for learning English conversation is reproduced and the image is displayed in the image display area A1.

  Further, keys K1 to K5 are displayed next to the image display area A1. The keys K1 to K5 are so-called software keys, and the electronic learning device 1 is caused to execute processing pre-assigned to the keys K1 to K5 by performing a touch operation on the keys K1 to K5 with a touch pen P or a finger. be able to.

  Keys K1 to K4 are dictionary keys for calling a dictionary. The dictionary assigned to the dictionary key is determined according to the content being reproduced. Each dictionary is assigned to a dictionary key with a priority according to the usage frequency of the dictionary.

  Here, since it is assumed that content related to English is being reproduced, the keys K1 to K4 are most likely to be used during English learning. The English-Japanese Dictionary G, English-Japanese Dictionary P, English-English Dictionary O and Japanese language dictionary K are assigned respectively. These dictionaries are assigned in order of use frequency.

  That is, here, a dictionary (English-Japanese dictionary G in this example) having the highest use frequency is assigned to the key K1 displayed at the top of the screen that is easily noticeable by the user and easy to be selected by the user. Hereinafter, the English-Japanese dictionary P, the English-English dictionary O, and the national language dictionary K are assigned to the keys K2 to 4 in order of use frequency.

  It should be noted that the display of the dictionary key is not limited as long as the dictionary key corresponding to the dictionary with the higher display priority is easier for the user to select than the dictionary key corresponding to the dictionary with the lower priority. It is not limited to the example. For example, a dictionary key corresponding to a dictionary with a high priority may be highlighted such as changing the color of other dictionary keys, turning it on, or displaying it larger than other dictionary keys.

  When a touch operation is performed on these dictionary keys, the electronic learning device 1 displays a screen for performing a keyword search using a dictionary associated with the dictionary keys. Thereby, the user can easily search for a word or a word whose meaning is to be confirmed during learning. Then, the dictionary corresponding to the content being reproduced is displayed in order of use frequency, so that the user can easily select a desired dictionary.

  The key K5 is a switching key for switching a dictionary to be selected. When a touch operation is performed on the switching key, the electronic learning device 1 uses other candidates for the dictionary that can be used for the search as dictionary keys. indicate. A dictionary that is not related to the content being played back or a dictionary that is not frequently used can be selected by operating this switching key.

  Here, when a touch operation is performed on the key K1, the electronic learning device 1 pauses the reproduction of the content and displays a screen as shown in FIG. In the illustrated example, a dictionary name (English-Japanese dictionary G) used for keyword search is displayed, and a keyword display area A2 and a keyboard K6 are displayed.

  That is, here, it is assumed that characters constituting a keyword (a term to be examined in the dictionary) used for the search are input by selecting characters included in the keyboard K6 with the touch pen P or the like. The input characters are displayed in the keyword display area A2, and by selecting “Enter” on the keyboard K6, a search is performed using the input character string as a keyword.

  In FIG. 6B, it is assumed that “Compliance” is entered and determined (the “Enter” key is entered), whereby the display as shown in FIG. 6C is performed. In the illustrated example, the name of the dictionary used for keyword search is displayed, and the result of searching for “Compliance” in the dictionary is displayed. Also displayed is a key K7 for ending the display of the dictionary search result and returning to the reproduction of the content.

  Here, when such a keyword search is performed, the electronic learning device 1 accesses the content reproduction time when the keyword search is performed and the data indicating the result of the keyword search. Is generated and stored. Here, it is assumed that the access information includes a dictionary ID of a dictionary subjected to keyword search, a keyword used for the search, and a keyword ID of the keyword.

  Then, when the electronic learning device 1 next reproduces the content, the electronic learning device 1 refers to the history data 32 and displays the keyword used for the search at the timing when the keyword search was performed in the past. An operation example when displaying a keyword will be described below.

[Operation Example of Electronic Learning Device 1 (Keyword Display)]
Next, an operation example when the electronic learning device 1 displays a keyword based on the history data 32 will be described with reference to FIG. FIG. 7 is a diagram showing an example of an operation when the electronic learning device 1 displays a keyword during content reproduction. FIG. 7A shows an example of a screen when no keyword is displayed. FIG. 4B shows an example of a screen when a keyword is displayed, and FIG. 4C shows an example of a screen when the displayed keyword is selected.

  As shown in FIG. 6A, when no keyword is displayed, the content image is displayed in the image display area A1 and keys K1 to K5 are displayed as in the example of FIG.

  Here, the electronic learning device 1 monitors whether the reproduction time of the content matches the reproduction time stored in the history data 32. When it is confirmed that the content matches, the electronic learning device 1 Display associated keywords. For example, when the playback time associated with the keyword “Compliance” is reached, as shown in FIG. 7B, a key K8 displayed as “Compliance” is displayed.

  When the displayed key K8 is selected with the touch pen P or the finger, the electronic learning device 1 displays the result of the search using the keyword “Compliance” as shown in FIG. 7C.

  As described above, the electronic learning device 1 displays the keyword used for the search at the timing when the keyword search has been performed previously. Since this keyword was previously examined by the user using the dictionary data 31, if the user memorizes the meaning or the like at that time, there is no need to display the search result by the keyword again. It is desirable to continue the playback. On the other hand, the user may have forgotten the results of previous searches.

  Therefore, when the displayed keyword is not selected, the electronic learning device 1 does not display the result of the search using the keyword, and displays the result of the search using the keyword when the displayed keyword is selected.

  Thereby, when it is determined that the display of the search result is unnecessary, the user can continue the reproduction of the content as it is. Further, since only the keywords are displayed, content viewing is not hindered. Then, when it is desired to confirm the search result, it can be confirmed without taking the trouble of inputting characters as shown in FIG.

  The search results may be displayed instead of displaying the keywords. However, if the search results are long, it is considered that the viewing of the content is hindered, and the search results by the keywords are remembered by the user. Since it is difficult to confirm whether or not it has been, it is preferable to display a keyword and display a search result when the keyword is selected.

  Moreover, the display of a keyword should just be an aspect which a user can recognize a keyword, and is not restricted to the example of FIG.7 (b). For example, the keyword may be displayed so as to be superimposed on the content image, such as a caption super.

  Further, when a plurality of keywords are recorded at the same playback time or near playback time, a plurality of keywords may be displayed simultaneously as in the example of FIG. FIG. 8 is a diagram illustrating an example in which a plurality of keywords are displayed simultaneously.

  In the example of FIG. 8, the keyword “CSR” is displayed in addition to “Compliance”. The user can select any of these keywords, and by selecting the keyword, the search result by the keyword can be confirmed.

  It is also conceivable that a user who selects a displayed keyword and confirms a search result based on the keyword determines that it is not necessary to display the keyword the next time the same content is reproduced. In other words, since the user's knowledge is fixed by repeatedly reproducing the content, it is preferable that the keyword to be displayed can be changed according to the degree of knowledge fixing.

  For example, a screen as shown in FIG. 9 may be displayed to allow the user to select whether or not to delete the record from the history data 32. FIG. 9 shows an example of a display screen for allowing the user to select whether or not to delete the record from the history data 32.

  In the example of FIG. 9, the key K7 displayed as “Close” is displayed and the key (deletion object) K10 displayed as “Delete” is displayed as in the example of FIG. 7B. Yes. That is, the user can delete the “Compliance” data from the history data 32 by selecting the key K10. Thus, the next time the same content is reproduced, the keyword “Compliance” is not displayed.

  Note that the timing for displaying the key K10 for deleting history data is not limited to the above example, and for example, the key K10 may be displayed when a keyword is displayed. Thereby, it is possible to delete the keyword history data without checking the search result.

  If the displayed keyword is not selected, it is considered that the user determines that the display of the search result of the keyword is unnecessary. Therefore, the history data 32 of the keyword that has not been selected is deleted. Also good.

[Process flow]
Next, the flow of processing executed by the electronic learning device 1 will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of processing executed by the electronic learning device 1.

  The reproduction processing unit 20 waits for selection of content to be reproduced (S1). Here, when it is confirmed that there has been a content reproduction instruction from an input operation on the input unit 10 (YES in S1), the reproduction processing unit 20 notifies the content type determination unit 25 to that effect. Receiving this notification, the content type determination unit 25 performs dictionary assignment processing and assigns a dictionary to each dictionary key (S2). Details of the dictionary assignment process will be described later.

  In addition, the reproduction processing unit 20 that has confirmed that there has been an instruction to reproduce the content reads the content instructed to reproduce from the moving image data 30 in the storage unit 13 and starts reproduction (S3). That is, it is assumed that the content to be reproduced here is a moving image content.

  Here, the search processing unit 21 waits for the selection of the dictionary key to which the dictionary is assigned in S2 (S4), and when it is confirmed that the dictionary key has been selected (YES in S4), the reproduction process is performed. The content reproduction is temporarily stopped by the unit 20 (S5), and the process proceeds to S6. On the other hand, if it is not confirmed that the dictionary key has been selected (NO in S4), the process proceeds to S12.

  In S6, the search processing unit 21 displays on the display unit 11 a keyword input screen corresponding to the selected dictionary key, more specifically, a keyword input screen for search using a dictionary assigned to the selected dictionary key. (S6) and wait for the search to be executed (S7).

  In S6, for example, when a dictionary key to which a dictionary for inputting a keyword in alphabet is assigned is selected, such as an English-Japanese dictionary, a keyword input screen for alphabet input is displayed. Similarly, when a dictionary key to which a dictionary for inputting keywords by kana is assigned as in the Japanese-English dictionary is selected, a keyword input screen for inputting kana is displayed.

  When a keyword is input and a search execution instruction is input, the search processing unit 21 searches for the keyword in the dictionary assigned to the dictionary key selected in S4, and the search result is displayed on the display unit 11. Display (S8). Further, the search processing unit 21 notifies the history data generation unit 22 of the keyword used for the search, the keyword ID of the keyword, and the dictionary ID of the dictionary used for the search.

  Receiving the above notification, the history data generation unit 22 acquires the current playback time of the content from the playback processing unit 20, that is, the playback time when paused in S5, and the acquired playback time and the search processing unit 21. The history data 32 is generated by associating the notified keyword, keyword ID, and dictionary ID, and stored in the storage unit 13 (S9).

  On the other hand, the search processing unit 21 displaying the search result in S8 checks whether or not to end the display of the search result (S10). Here, when it is confirmed that the display of the search result is finished (YES in S10), the search processing unit 21 instructs the reproduction processing unit 20 to resume the reproduction of the content. As a result, the display of the search result is completed, and the image of the content is displayed on the display unit 11 instead (S11).

  The reproduction processing unit 20 that has resumed the reproduction confirms whether or not to end the reproduction of the moving image (S12). If it is confirmed that the reproduction is not terminated (NO in S12), the process returns to S4. On the other hand, when it is confirmed that the moving image reproduction is to be ended (YES in S12), the process proceeds to S13, and the reproduction processing unit 20 ends the reproduction of the moving image. In addition, the reproduction processing unit 20 notifies the dictionary display order determination unit 24 that the reproduction of the moving image is to be ended.

  In S12, the reproduction processing unit 20 determines that the moving image reproduction is to be terminated when the reproduction is performed until the end time of the content being reproduced, or when the input unit 10 accepts an input operation for ending reproduction.

  The dictionary display order determination unit 24 that has received the notification to end the reproduction of the video performs a history totaling process (S14), whereby the history of the search performed during the content reproduction is stored in the usage history total data 33. Reflected. Details of the history tabulation process will be described later.

  In S11, the playback processing unit 20 may restart playback from the position where the playback of the content is stopped, but from the stopped playback position (playback position when the input operation for starting the search is performed). Playback may be resumed from the previous playback position (close to the beginning of the content). This is because there is a difference between the timing that triggers the search (for example, when an unknown term is used) and the timing when the user performs an input operation to start the search. In other words, by restarting the content playback from before the content playback position that triggered the search, the user can recognize the search result scene (for example, an unknown term It is possible to check the scenes where the is used, and to deepen the understanding of the content.

[Keyword display processing]
Next, a keyword display process in which the electronic learning device 1 displays a keyword will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of the keyword display process. The keyword display process is a process performed during content reproduction.

  The reproduction processing unit 20 that has confirmed that there has been a content reproduction instruction from the input operation on the input unit 10 reads the content instructed to reproduce from the moving image data 30 in the storage unit 13 and starts reproduction (S20).

  When the reproduction of the content is started, the keyword display processing unit 23 refers to the history data 32 to determine whether there is a match between the current reproduction time of the content and the reproduction time stored in the history data 32. Confirm (S21).

  If no match is confirmed (NO in S21), the process proceeds to S32. On the other hand, if a match is confirmed (YES in S21), the keyword display processing unit 23 specifies a keyword associated with the playback time that matches the current video data playback time in the history data 32. To do. Then, the keyword display processing unit 23 displays the identified keyword on the display unit 11 (S22). Then, the keyword display processing unit 23 checks whether or not the displayed keyword is selected (S23).

  Here, when the selection of the keyword is not confirmed (NO in S23), the keyword display processing unit 23 confirms whether or not a predetermined time has elapsed after the keyword is displayed (S24).

  If it is confirmed that the predetermined time has passed (YES in S24), the keyword display processing unit 23 ends the keyword display (S25), and proceeds to the process of S32. On the other hand, if it is not confirmed that the fixed time has passed (NO in S24), the process returns to S23.

  Here, when it is confirmed in S23 that a keyword has been selected (YES in S23), the keyword display processing unit 23 instructs the reproduction processing unit 20 to pause reproduction (S26). In addition, the keyword display processing unit 23 notifies the search processing unit 21 of the selected keyword and information indicating a dictionary searched with the keyword. Receiving this notification, the search processing unit 21 searches the dictionary notified by the notified keyword, and displays the result on the display unit 11 (S27).

  The search processing unit 21 that has displayed the search result confirms whether or not to end the display of the search result (S28). If it is confirmed that display of the search result is to be ended (YES in S28), the search processing unit 21 determines whether to delete the record of the history data 32 corresponding to the keyword displaying the search result. (S29).

  For example, if the search result is displayed on the screen as shown in FIG. 9 in S27, when the key K10 is selected, it is determined that the display of the search result is ended (YES in S28) and recorded. Is determined to be deleted (YES in S29). On the other hand, when the key K7 is selected in the screen example of FIG. 9, it is determined that the display of the search result is terminated (YES in S28), and it is determined not to delete the record (NO in S29).

  If it is confirmed in S29 that the recording is to be deleted (YES in S29), the search processing unit 21 notifies the history data generation unit 22 to that effect. Upon receiving this notification, the history data generation unit 22 deletes the corresponding record from the history data 32. For example, when the key K10 is selected in the screen example of FIG. 9, the history data corresponding to the keyword “Compliance” is deleted.

  In S31, the search processing unit 21 instructs the reproduction processing unit 20 to resume content reproduction. As a result, the display of the search result ends, and the content image is displayed instead.

  The reproduction processing unit 20 that has resumed the reproduction of content confirms whether or not to end the reproduction of the moving image (S32). If it is confirmed that the reproduction is not completed (NO in S32), the process returns to S21. On the other hand, if it is confirmed that the reproduction of the content is to be ended (YES in S32), the process proceeds to S33, and the reproduction processing unit 20 ends the reproduction of the content, thereby ending the keyword display process.

  In the above example, when the current playback time of the content matches the playback time stored in the history data 32, the keyword associated with the playback time is displayed. The keyword may be displayed before the reproduction time of the history data 32.

  For example, if the keyword display timing is shifted before the content playback position when the input operation for starting the search is accepted, the content playback position that triggered the search is actually This is preferable because the deviation from the reproduction position when the search is performed can be reduced.

[Dictionary assignment processing]
Next, details of the dictionary assignment processing performed in S2 of FIG. 10 will be described based on FIG. FIG. 12 is a flowchart illustrating an example of the dictionary assignment process.

  First, the content type determination unit 25 determines the type of content being played back by the playback processing unit 20 (S40), and notifies the dictionary key display processing unit 26 of the determination result. A content type determination method will be described later.

  Next, the dictionary key display processing unit 26 that has received the determination result of the content type specifies a dictionary corresponding to the notified content type (S41). Specifically, the dictionary key display processing unit 26 refers to the type-dictionary correspondence data 35 and specifies a dictionary associated with the notified type.

  Subsequently, the dictionary key display processing unit 26 determines the order of the dictionary (S42). Specifically, the dictionary key display processing unit 26 refers to the dictionary display order data 34, and the dictionaries specified in S41 are arranged in order from the smallest “order” value defined in the dictionary display order data 34. In this way, the order of dictionaries is determined. Subsequently, the dictionary key display processing unit 26 determines the order of dictionaries so that dictionaries other than the dictionary specified in S41 are arranged in descending order of the “order” value defined in the dictionary display order data 34. To do. Thereby, the arrangement order (display priority) of all the dictionaries is determined.

  Finally, the dictionary key display processing unit 26 assigns a dictionary to the dictionary key in accordance with the arrangement order determined in S42 (S43), and ends the dictionary assignment process. Specifically, the dictionary key display processing unit 26 displays a predetermined number of dictionary keys on the display unit 11 and displays dictionary names on the displayed dictionary keys according to the arrangement order determined in S42. For example, the dictionary that is not assigned to the dictionary key is displayed when the key K5 in FIG. 6A is selected and the display of the dictionary key is switched.

  Thereafter, when a dictionary key is selected, the search processing unit 21 performs a search in the dictionary associated with the selected dictionary key by the dictionary key display processing unit 26.

[Content type judgment method]
Next, a method in which the content type determination unit 25 determines the content type will be described with reference to FIG. FIG. 13 is a diagram showing the configuration of a folder storing content in a tree format. In the figure, in order to distinguish between a folder and a file, (F) is added after the name of the folder.

  In the example of FIG. 13, the “content” folder includes a “text” folder and a “moving image” folder. The “Text” folder includes a “Japanese history” folder in which “person encyclopedia.pdf” and the like are stored, and a “World History” folder in which “world map.pdf” and the like are stored. ing.

  The “Movie” folder stores subject folders of “National Language”, “Mathematics”, and “English”, and “Country I” that further classifies the subject in each subject folder. , “Number I”, “TOEIC 600 point break course” and the like are included. In the “TOEIC 600 points breakthrough course” folder, three moving image files “TOEIC 600 points breakthrough course (1) .avi” to “TOEIC 600 points breakthrough course (3) .avi” are stored.

  As described above, in the example of FIG. 13, the content is classified and divided into folders according to the standard “subject”. Therefore, the content type determination unit 25 identifies a folder in which the content being reproduced is stored, and confirms to which “department” the folder belongs to which “subject”. Can be determined.

  Note that the content type determination method is not limited to the above example. For example, when the type of content is included in information such as a property added to the content file, the type of content can be determined by referring to this information. Further, for example, when information associated with the content is recorded in a file (for example, an XML file) different from the content file, the type of the content is determined by referring to the file. You can also.

[History summary processing]
Next, details of the history tabulation process performed in S14 of FIG. 10 will be described based on FIG. FIG. 14 is a flowchart illustrating an example of the history tabulation process.

  First, the dictionary display order determination unit 24 refers to the history data 32 and counts the number of times each dictionary is used. Then, the usage history count data 33 is generated by associating the counted number of times of use with the dictionary ID of the dictionary (S50).

  Next, the dictionary display order determination unit 24 stores the use history total data 33 generated in S50 in the storage unit 13. That is, the dictionary display order determination unit 27 updates the usage history total data 33 based on the usage count counted in S50 (S51). As a result, the history tabulation process ends.

[Example of counting search histories on multiple devices]
In the above description, the example in which the display order of the dictionary is determined based on the history of the search performed in the electronic learning device 1 has been described. However, the display order of the dictionary is determined based on the history of the search performed in a plurality of devices. May be.

  Here, an example of an electronic learning system that determines the display order of dictionaries based on the history of searches performed by a plurality of devices will be described with reference to FIG. FIG. 15 is a block diagram showing a main configuration of an electronic learning device (content reproduction device) 40 and a server (aggregation device) 50 included in the electronic learning system 60. In addition, about the structure similar to the electronic learning apparatus 1 of FIG. 1, the same reference number is attached | subjected and the description is abbreviate | omitted.

  Compared to the electronic learning device 1 of FIG. 1, the electronic learning device 40 includes a communication unit 14, and the dictionary display order determination unit 24 has a dictionary display order determination unit (priority data generation means, usage history data generation). Means) The point of replacing 27 is different. The usage history total data (terminal) 33 stored in the storage unit 13 is different in name from the usage history total data 33 in FIG. 1, but has the same data configuration.

  The communication unit 14 is for the electronic learning device 40 to communicate with other devices. Here, it is assumed that the electronic learning device 40 is connected to the communication network from the communication unit 14 and communicates with the server 50 via the communication network.

  The dictionary display order determination unit 27 transmits usage history total data (terminal) indicating the history of the search performed by the own device to the server 50. Thereby, the server 50 can generate usage history total data (server) (integrated usage history data) reflecting the history of the search performed by the electronic learning device 40.

  Then, the dictionary display order determination unit 27 receives the usage history total data (server) generated (updated) by the server 50 and updates the usage history total data (terminal) 33. Since the history of searches in other devices is also reflected in the usage history total data (server), the history of searches in other devices is reflected in the usage history total data (terminal) 33 by the above update.

  The server 50 receives the usage history total data (terminal) transmitted from the electronic learning device 40, updates the usage history total data (server), and transmits the updated usage history total data (server) to the electronic learning device 40. It is a device to do. As illustrated, the server 50 includes a server communication unit 51, a server control unit 52, and a server storage unit 53.

  The server communication unit 51 is for the server 50 to communicate with other devices. Here, it is assumed that the server communication unit 51 communicates with the electronic learning device 40 and a device that generates and transmits usage history total data (terminal) 33 in the same manner as the electronic learning device 40 via the communication network. Yes.

  The server control unit 52 controls the operation of the server 50 in an integrated manner, and the server control unit 52 includes a usage history totaling unit 54. The usage history totaling unit 54 receives the usage history total data (terminal) transmitted from the electronic learning device 40, updates the usage history total data (server), and uses the updated usage history total data (server) as the electronic learning device. 40.

  The server storage unit 53 stores various data used by the server 50, and the server storage unit 53 includes usage history total data (server) 55. The usage history total data (server) 55 is data reflecting dictionary usage history in a plurality of apparatuses. The usage history total data (server) 55 may be anything as long as information specifying a dictionary is associated with information indicating the frequency of use of the dictionary, for example, as shown in FIG. .

[History tabulation processing (terminal side)]
Next, the history totaling process (terminal side) executed by the electronic learning device 40 will be described with reference to FIG. FIG. 16 is a flowchart illustrating an example of a history tabulation process (terminal side) executed by the electronic learning device 40. This process is performed in S14 of FIG. 10 instead of the process of FIG.

  First, the dictionary display order determination unit 27 refers to the history data 32 and counts the number of times each dictionary is used. Then, the usage history count data (terminal) 33 is generated by associating the counted number of times of use with the dictionary ID of the dictionary (S60).

  Next, the dictionary display order determination unit 27 transmits the use history total data (terminal) 33 generated in S60 to the server 50 via the communication unit 14 (S61). The server 50 that has received the usage history total data (terminal) 33 transmits the usage history total data (server) 55 to the electronic learning device 40 by a history totaling process (server side) described later.

  Then, the dictionary display order determination unit 27 receives the usage history total data (server) 55 (S62), and stores the received usage history total data (server) 55 in the storage unit 13 as usage history total data (terminal) 33. To do. That is, the dictionary display order determination unit 27 updates the usage history total data (terminal) 33 with the usage history total data (server) 55 (S63). Thereby, the history totaling process (terminal side) ends.

  By determining the display order of dictionaries using the usage history total data (terminal) 33 updated in this way, dictionaries frequently used by users of other devices are also preferentially assigned to dictionary keys. For this reason, it is possible to recognize what kind of dictionary the user of another device is using, and it is also possible to select a dictionary that is frequently used by other users.

[History summary processing (server side)]
Next, the history totaling process (server side) executed by the server 50 will be described with reference to FIG. FIG. 17 is a flowchart illustrating an example of a history totaling process (server side) executed by the server 50.

  The usage history totaling unit 54 of the server 50 receives the usage history totaling data (terminal) 33 transmitted by the dictionary display order determining unit 27 of the electronic learning device 40 (S70). Subsequently, the usage history totaling unit 54 updates the usage history totaling data (server) 55 stored in the server storage unit 53 using the received usage history totaling data (terminal) 33 (S71). Specifically, the usage history totaling unit 54 adds each count number included in the received usage history total data (terminal) 33 to the count number of the corresponding dictionary ID in the usage history total data (server) 55. As a result, the usage history total data (server) 55 is updated.

  The count number stored in the usage history total data (server) 55 is a count of the counts of the usage history total data (terminal) 33 received from the electronic learning device 40 and / or other devices. The updated number of counts is obtained by counting the usage history tabulated data (terminal) 33 of the electronic learning device 40 and / or other devices.

  Then, the usage history totaling unit 54 transmits the updated usage history totaling data (server) 55 to the electronic learning device 40 via the server communication unit 51 (S72). Thereby, the history tabulation process (server side) ends.

[Modification of usage data]
Although the example in which the dictionary display order is determined using the dictionary display order data 34 generated from the usage history total data 33 has been described above, the dictionary display order can also be determined directly from the usage history total data 33. For example, when the usage history total data 33 of FIG. 3 is used, the display order may be determined in descending order of the number of counts.

  In the above description, the usage history total data 33 is generated using the history data 32. However, it is of course possible to generate the usage history total data 33 without using the history data 32. For example, a configuration for counting the number of searches for each dictionary may be provided, and the usage history total data 33 may be generated by this configuration. However, when the history data 32 is used, it is not necessary to increase the configuration of the electronic learning device 1, so it is preferable to use the history data 32.

[Modification of dictionary data storage destination]
In the above description, the example in which the dictionary data 31 is stored in the storage unit 13 included in the electronic learning device 1 has been described. However, the electronic learning device 1 can present a search result based on the dictionary data 31 to the user. If so, the dictionary data 31 may be stored in another device. Further, the search using the dictionary data 31 may be performed by a device other than the electronic learning device 1 and the electronic learning device 1 may acquire the search result.

  In this case, the electronic learning apparatus 1 should just be provided with the communication part 14 like the electronic learning apparatus 40 of FIG. And the search process part 21 should just make the external apparatus perform the search using a keyword, and should display the result.

  Specifically, the search processing unit 21 displays a keyword input screen for inputting a keyword on the display unit 11. Then, the keyword input by the input unit 10 during the display of the keyword input screen, the information for specifying the database to be searched with the keyword, and the search execution instruction by the keyword are externally transmitted via the communication unit 14. Send to device. Then, the search result is received from an external device and displayed on the display unit 11.

[Modification of configuration for displaying search results]
In the above description, an example has been described in which, when a keyword displayed during content reproduction is selected, a search result is displayed by performing a search again using the selected keyword. However, the electronic learning device 1 or 40 only needs to be able to display the search result using the selected keyword when the keyword displayed at the time of content reproduction is selected, and is limited to the above example. Absent.

  For example, the search result may be included in the history data 32. In this case, when a keyword is selected, the search result can be acquired from the history data 32, so that the search result can be displayed without performing a search again. Further, for example, the search result may be stored separately from the history data 32, and information for accessing the search result (for example, the storage address of the search result) may be included in the history data 32.

  In particular, as in the configuration described in [Modification of Dictionary Data Storage Destination], when searching in an external database, it is expected that re-searching will take time. It is preferable to store in the inside.

[Search target database]
Although the example which searches a keyword in either databases, such as a national language dictionary and an English-Japanese dictionary, was demonstrated above, the database used for a search is not restricted to these examples. For example, a database such as an encyclopedia or dictionary may be used, or a dictionary database of foreign languages other than English may be used. Further, for example, a search may be performed using a database provided on a network such as the Internet.

  In addition, when performing a search in a database on a network, it is conceivable to perform a search by adding a keyword or a search condition to obtain a desired search result.

  When such a search is performed, information (for example, an address) for accessing the final search result may be stored in the history data 32. In addition, the search condition may be stored in the history data 32. In this case, the search is performed again using the stored search condition.

  Furthermore, the search using the database is not limited to the keyword search, and any search method can be applied. Also in this case, information for accessing the search result may be stored in the history data 32 according to the search method.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope shown in the claims. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.
