Description

  The present invention relates to a content reproduction apparatus that reproduces content such as moving images, a control method for the content reproduction apparatus, a control program, and a recording medium.

  In recent years, learning systems that perform learning using a terminal device such as a personal computer have become widespread. In such a learning system, learning content such as images and voices is reproduced on a terminal device, and the user learns by viewing the content.

  According to the learning system as described above, there is an advantage that it is possible to take a lecture without going to the instructor, and to provide a lecture with the same contents to a large number of persons at remote locations. For this reason, various techniques for further improving the convenience of the learning system have been proposed.

  For example, in the following Patent Document 1, a user inputs a comment during playback of an electronic teaching material, and the input comment and the playback time of the electronic teaching material when the comment is input are stored in association with each other. Is described. In Patent Document 1, when the comment is displayed and the displayed comment is selected, the electronic teaching material is reproduced from the reproduction time associated with the comment, that is, the comment is used as a bookmark. It is described to review.

JP 2007-150552 A (released on June 14, 2007) JP 2010-015042 A (published January 21, 2010)

  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.

  For example, when a term is examined using a paper-based dictionary or an electronic dictionary while the learning content is being reproduced, the term and / or the result of the examination are shown by using the technique of Patent Document 1 or 2. The text can be stored in association with the learning content playback time.

  However, in order to store the examined term in the terminal device, it is necessary to input the term into the terminal device, and such processing is troublesome for the user. Patent Documents 1 and 2 use a comment as a bookmark for learning content. When one comment is selected from a list of comments displayed, the learning time is determined from the playback time associated with the comment. Content playback starts.

  For this reason, when the user wants to confirm the meaning of the term after selecting a comment and starting playback, the user needs to stop playing the learning content and check the dictionary again. There is.

  Furthermore, since there is time until the user actually records the comment after the term that the user wants to check is found, the playback time associated with the comment and the playback time at which the term checked by the user appears Is different. Specifically, the playback time associated with the comment is later than the playback time at which the term examined by the user appears.

  For this reason, when the learning content is started to be played back from the playback time associated with the comment, there is a problem in that the scene in which the term examined by the user appears is not played back. Then, in order to confirm the scene of the content that triggered the search, the user must perform an operation of returning the content reproduction position, which hinders smooth learning.

  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 the object of the present invention is content that triggers a search when the user resumes the reproduction of the content after performing the search during the reproduction of the content. It is an object of the present invention to provide a content playback apparatus or the like that can confirm the above scenes without operating the playback position.

  In order to solve the above-described problems, a content playback apparatus according to the present invention is a content playback apparatus that plays back content, and includes an input unit that accepts a user input operation, and an input to the input unit during playback of the content. A search means for performing a search using a database according to the operation and displaying the search result, and an input operation for the input unit to start searching for the playback position of the content when the playback of the content is resumed Content reproduction means for returning the content by a predetermined content return time from the content reproduction position when the content is received.

  In addition, 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, an input step for receiving a user input operation, and the content playback device During the playback of the content, a search step for performing a search using the database according to the input operation in the input step and displaying the search result, and the playback position of the content when restarting the playback of the content, A content playback step of returning the content by a predetermined content return time from the content playback position when the input operation for starting the search is accepted in the input step.

  According to the above configuration, when the content reproduction apparatus is reproducing the content, the input operation for starting the search is accepted, the database is searched, and the search result is displayed. You can search during playback and check the search results. For example, when a matter that the user does not know appears during playback of the content, the user can check the meaning of the matter by searching the matter from the database.

  Furthermore, when the content reproduction apparatus resumes the reproduction of the content, the content reproduction position is set to a predetermined content return time from the content reproduction position when the input operation for starting the search is accepted. Go back.

  Therefore, as the content return time, the input for the user to start the search from the playback position of the content that triggered the search (for example, the playback position when a matter that the user does not know is used in the content) By setting a time longer than the required time until the operation is performed, the reproduction of the content is resumed from before the reproduction position of the content that triggered the search.

  Therefore, after viewing the search result and confirming the meaning of the matter, the user can confirm again the scene that triggered the search without manipulating the playback position of the content. For example, if the user does not understand the meaning of a term used in the content, the user searches the database for the meaning of the term, and then operates the playback position of the scene of the content in which the term is used. It can be confirmed without.

  Note that when the above-described content reproduction is resumed, the content is paused when the search is performed during the reproduction of the content, and after the user finishes browsing the search result, the content is reproduced again. It may be. In addition, when the reproduction of the content is resumed, even when the content is reproduced and the search is performed during the reproduction of the content, even when the user ends the confirmation of the search result and returns to the viewing of the content. Good.

  Further, it is preferable that the content reproduction means resumes the reproduction of the content when the search means finishes displaying the search result.

  According to the above configuration, the content reproduction means resumes the reproduction of the content when the search means finishes displaying the search result.

  Therefore, the user who has finished checking the search result can return to viewing the content without performing any operation. Note that the search result display termination is not particularly limited. For example, the search result may be triggered by a user's operation, or after the search result is displayed, the search result may be displayed for a predetermined time (the user can confirm the content of the search result It may be triggered by the elapse of time.

  Further, the content playback apparatus according to the present invention, when playing back the content that has been searched by the search means in the past, when the input unit accepts an input operation for starting the search at the time of the search It is preferable to provide an object display means for displaying an object for displaying the search result when the playback position is a predetermined display timing correction time before the content playback position.

  Here, when the content searched in the past is replayed, the search result may be forgotten by the user, so that the search result can be easily confirmed at the timing when the search is performed in the past. If it is, it is convenient. However, as described above, there is a difference between the playback position of the content that triggered the search and the playback position when the search is actually performed.

  For this reason, when the above-mentioned object is displayed at the playback position when the search is actually performed, it may be too far from the playback position of the content that triggered the search, resulting in poor usability. For example, when the meaning of a term used in the content is examined, if the object is displayed for a while after the scene in which the term is used is completed, smooth viewing of the content is hindered.

  Therefore, according to the above configuration, when the content that has been searched by the search means in the past is played back, the content when the input unit accepts an input operation for starting the search at the time of the search An object for displaying the search result is displayed when the playback position is a predetermined display timing correction time before the playback position.

  In this way, by shifting the object display timing before the content playback position when the input operation for starting the search is accepted, the playback position of the content that triggered the search and the actual search are performed. It is possible to reduce the deviation from the reproduction position when performing.

  In other words, according to the above configuration, an object can be displayed at a playback position that is closer to the playback position of the content that triggered the search, so that the user can check the search result at a more desirable timing. it can. Further, when the user determines that there is no need to reconfirm the search result, the user can continue to view the content as it is without selecting an object.

  Note that the display timing correction time is the time when the user starts searching from the playback position of the content that triggered the search (for example, the playback position when an item unknown to the user is used during playback). It is preferable to set it longer than the time required for performing the input operation.

  As a result, when the content that has been searched by the search means in the past is played back, the object is displayed at the playback position that triggered the search, so that the search result can be confirmed at the playback position. .

  For example, if a user wants to check the search result again while viewing a scene in which a term searched in the past is used, the search result can be selected with a very simple operation of selecting a displayed object. Can be presented. Further, when it is determined that there is no need to reconfirm the search result, the user can continue viewing the content as it is.

  Also, the content playback apparatus of the present invention provides position information indicating the playback position of the content when the input unit accepts an input operation for starting a search, and access information for accessing a search result by the search means History data generating means for generating history data in association with each other, the object display means refers to the history data generated by the history data generation means, specifies the timing for displaying the object, and When the object displayed by the display means is selected, it is preferable to include search result display means for displaying the search result acquired using the access information included in the history data.

  According to the above configuration, the history data generation unit accesses the position information indicating the reproduction position of the content when the input unit receives an input operation for starting the search, and the search result by the search unit. History data associated with the access information is generated.

  Further, the object display means refers to the history data and specifies the timing for displaying the object. Since the history data includes position information indicating the reproduction position of the content when the input unit accepts an input operation for starting a search, the reproduction position that is the display timing correction time before the reproduction position indicated by the position information. Can be specified as the display timing of the object.

  The search result display means displays the search result acquired using the access information included in the history data when the object displayed by the object display means is selected. Since the object is displayed based on the position information included in the history data, the position information used for displaying the object can be specified from the selected object, and further, the object is associated with the position information. Can identify the access information. Therefore, when an object is selected, access information corresponding to the object can be specified, and a search result can be acquired and displayed using this access information.

  Note that the retrieval result acquisition method depends on what information is the access information. For example, when the access information is information specifying a database that has been searched and a search condition, a search result can be obtained by performing a search again using that database under that condition. 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.

  In the content reproduction apparatus of the present invention, the search means performs a search using a keyword received by the input unit, the history data generation means generates history data including the keyword, and the object display means Preferably, the object including the keyword included in the history data generated by the history data generating means is displayed.

  According to said structure, the said search means performs the search by the keyword input into the said input part, The said log | history data production | generation means produces | generates the log | history data containing the said keyword, The said object display means is the said keyword Displays objects that contain

  That is, according to the above configuration, when the content that has been searched by the search means in the past is played back, the object including the keyword input to the input unit is displayed. Therefore, the user can recognize that a search has been performed in the past with the displayed keyword. If the search result is forgotten, the search result can be reconfirmed by selecting an object including the keyword.

  In addition, the content playback apparatus of the present invention can store the object or history data corresponding to the search result when the object display means displays the object or when the search result display means displays the search result. It is preferable to include history data deleting means for displaying a deletion object for deletion.

  According to the above configuration, the deletion object for deleting the object or the history data corresponding to the search result is displayed. Therefore, the user selects the deletion object and deletes the history data corresponding to the object or the search result, so that the object or the search result is not displayed when the content is reproduced after the next time. be able to. This is useful, for example, when the user has already stored the search results (displayed when an object is selected).

  In order to solve the above-described problem, the content playback device of the present invention is a content playback device that plays back content, and includes an input unit that accepts a user input operation, and the input unit during content playback. In accordance with the input operation, when a search is performed using a database and the search results are displayed, and the content that has been previously searched by the search means is played back, the input unit An object for displaying the search result is displayed when the playback position is a predetermined display timing correction time before the content playback position when the input operation for starting the search is accepted. And an object display means.

  According to the above configuration, when content that has been searched by the search means in the past is played back, the content is played back when the input unit receives an input operation for starting the search during the search. An object for displaying the search result is displayed when the playback position comes before the position by a predetermined display timing correction time.

  Therefore, the object can be displayed at a reproduction position that is closer to the reproduction position of the content that triggered the search, and the user can check the search result at a more desirable timing.

  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 reproduction apparatus according to the present invention performs a search using a database according to an input operation to the input unit that receives an input operation of a user and the input unit during content reproduction, and the search result is obtained. Content that has been determined in advance from the search means to display and the playback position of the content when the playback of the content is resumed from the playback position of the content when the input unit accepts an input operation to start the search The content reproduction means is provided with a content reproduction means for returning by the return time.

  In addition, as described above, the method for controlling the content playback apparatus of the present invention uses a database in accordance with the input step for accepting a user input operation and the input operation in the input step while the content playback apparatus is playing back the content. A search step for performing a search and displaying the search result, and a content when the input operation for starting the search in the input step is accepted for the reproduction position of the content when the reproduction of the content is resumed And a content playback step of returning by a predetermined content return time from the playback position.

  Accordingly, when the user resumes the content reproduction after the user performs a search during the reproduction of the content, the user can check the scene of the content that is the trigger of the search without operating the reproduction position. it can.

It is a block diagram which shows the principal part structure of the electronic learning apparatus and server which are contained in the electronic learning system concerning one Embodiment of this invention.

  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 (content reproduction unit) 20, a search processing unit (search unit, search result display unit) 21, a history data generation unit ( A history data generation unit, a history data deletion unit) 22, and a keyword display processing unit (object display unit) 23.

  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).

  Furthermore, the reproduction processing unit 20 inputs a keyword into the input unit 10 during reproduction of the content, the search processing unit 21 performs a search and displays the search result, and when the user finishes browsing the search result (search When the processing unit 21 finishes displaying the search result), the content of the content from the playback time that is a predetermined content return time before the playback time of the content when the search start instruction is input to the input unit 10. Resume playback. In other words, the reproduction processing unit 20 determines the content reproduction position in advance from the content reproduction position when the input unit 10 receives an input operation for starting the search when resuming the reproduction of the content. Move back by the content return time. Details of the content return time will be described later.

  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 when a search start instruction (dictionary selection keys K1 to K3 described later) is input to the input unit 10 during reproduction of content. It is displayed on the display unit 11. When a keyword is input to the input unit 10, the search processing unit 21 searches the database using the keyword received by the input unit 10 during display of the keyword input screen, and displays the search result on the display unit 11. To display. Here, it is assumed that the database to be searched is dictionary data stored in the storage unit 13. That is, the search processing unit 21 performs a search using the database in accordance with an input operation to the input unit 10 during content reproduction, and displays the search result.

  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 (time information) indicating a reproduction position of the content (reproduction position from the top of the content) when the keyword search is performed, and a search result by the keyword. History data is generated by associating the access information and the keyword with the keyword and stored in the storage unit 13. Here, it is assumed that the reproduction time of content is used as the position information, and information indicating a database to be searched and a keyword used for the search are used as the access information.

  Although the details will be described later, the position information included in the history data by the history data generation unit 22 is to access the search result at the timing when the user searches the past when the same content is reproduced next time. It is used to make it possible. For this reason, the said positional information should just be what can identify the timing which performed the search.

  Here, it is assumed that the content reproduction time when the input unit 10 receives an input operation for starting a search is used as the position information. Of course, the position information is not limited to this example as long as it indicates the reproduction position of the content when the search is performed. For example, position information indicating when a keyword is input, when a search is executed, when a search result is displayed, or when display of a search result ends may be used. The access information is not limited to this example as long as it is information that can access the search result.

  The keyword display processing unit 23 displays the keyword used for the search on the display unit 11 at a timing earlier than the timing at which the keyword search was performed in the past when the content is reproduced. Specifically, the keyword display processing unit 23 refers to the display timing correction time included in the setting data 33 and the history data generated by the history data generation unit 22, and from the timing when the keyword search has been performed in the past. The timing earlier by the display timing correction time and the keyword used for the search are specified, and the above display is performed. More specifically, the keyword display processing unit 23 determines that the playback position of the content is the input unit 10 during the search while the playback processing unit 20 is playing back the content searched by the search processing unit 21 in the past. An object (keyword) for displaying the search result when the playback position is a predetermined display timing correction time before the playback position of the content when the input operation for starting the search is received. ) 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 storage unit 13 stores various data used by the electronic learning device 1, and includes moving image data (content) 30, dictionary data (database) 31, history data 32, and setting data 33.

  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 three dictionaries, a national language dictionary, an English-Japanese dictionary, and a Japanese-English dictionary, is stored as the dictionary data 31. ing. 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. This is data in which information is associated with the keyword.

  The setting data 33 is data indicating values of content return time and display timing correction time currently set in the electronic learning device 1. The content return time and display timing correction time values included in the setting data 33 may be predetermined values as defaults, or the user may set the content return time and display timing correction time values. Good.

[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 data in which a number, a reproduction time, a usage dictionary, and a keyword are associated with each other.

  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 a keyword search is performed during the reproduction of the content (when the input unit 10 accepts an input operation for starting the search). 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 started.

  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 history data 32 may be any data that can identify the timing at which the keyword search was performed in the past and the keyword, and can identify information for accessing the search result by the keyword. It is not restricted to the example of FIG.

  For example, history data 32 as shown in FIG. 3 may be used. FIG. 3 is a diagram illustrating another example of the history data 32. The history data 32 in FIG. 3 is different from the history data 32 in FIG. 2 in that dictionary ID and keyword ID data are added.

  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.

  As described above, FIG. 2 and FIG. 3 show an example in which a keyword and a used dictionary or a dictionary ID and a keyword ID are included in the history data 32 as information for accessing a search result by keyword. However, the history data 32 only needs to include the reproduction time and access information for accessing the search result by the keyword, and is not limited to the above example. For example, information (address or the like) indicating the storage location of the search result may be included as access information.

[About setting data 33]
The setting data 33 may be data as shown in FIG. 4, for example. FIG. 4 is a diagram illustrating an example of the setting data 33. In the illustrated setting data 33, the content return time is set to 60 seconds, and the display timing correction time is set to 30 seconds.

  In the illustrated example, the content return time is set to 60 seconds and the display timing correction time is set to 30 seconds. However, the values of the content return time and the display timing correction time are not limited thereto. The value of the content return time is determined from the time when the term comes out during the playback of the content (when the search trigger occurs) so that the user can view the content after confirming the meaning of the term. It is desirable that the time is set longer than the time until the user inputs a search start instruction for the term.

  In addition, when the term that is the target of the search is used at the latest, the display timing correction time value is displayed when the term appears during playback of the previous content in order to display a key indicating the term. It is desirable that the time is set to be equal to or longer than the time from when the search trigger occurs until the user inputs a search start instruction for the term.

  In the illustrated example, the content return time is set to 60 seconds and the display timing correction time is set to 30 seconds, but different values are set. However, the present invention is not limited to this. May be set.

  The keyword display timing is preferably close to the timing at which the keyword is used in the content. On the other hand, if the term you want to search for appears while viewing the content, you may not be able to understand the content of the previous content, so the position where playback resumes is before the timing at which the keyword was used. It is preferable that For this reason, it is preferable to set the content return time longer than the display timing correction time as in this example.

  By using the above-described history data 32 and the display timing correction time included in the setting data 33, when reproducing “training video 1-1”, the display timing is higher than the timing at which a keyword search was performed in the past. The keyword used for the keyword search can be displayed at the timing before the correction time. When the displayed keyword is selected, the search by the keyword can be executed again and the search result can be displayed.

[Example of operation of electronic learning device 1 (history data generation / recording and content return playback)]
Next, an operation example of the electronic learning device 1 will be described with reference to FIG. FIG. 5 is a diagram illustrating an operation example of the electronic learning device 1. FIG. 5A is a diagram before selecting a dictionary, FIG. 5B is a keyword search using the selected dictionary, and FIG. 5C is a keyword. An example of operation after execution of a search is shown.

  In the example of FIG. 6A, an image of content is displayed in the image display area A1, and keys K1 to K3 are displayed next to the image display area A1. The keys K1 to K3 are so-called software keys, and the electronic learning device 1 is caused to execute processing pre-assigned to the keys K1 to K3 by performing a touch operation on the keys K1 to K3 with the touch pen P or a finger. be able to. Specifically, when the keys K1 to K3 are selected, the search is started.

  Specifically, the key K1 is a key for calling a Japanese language dictionary. When a touch operation is performed on the key K1, the electronic learning device 1 displays a keyword search screen using the national language dictionary. Thus, when a term whose meaning is to be confirmed appears during learning, the user can easily search for the term.

  The key K2 is a key for calling an English-Japanese dictionary. When a touch operation is performed on the key K2, the electronic learning device 1 displays a keyword search screen using the English-Japanese dictionary. As a result, the user can easily search for a Japanese translation of English when the user wants to confirm the meaning during learning.

  The key K3 is a key for calling up a Japanese-English dictionary. When a touch operation is performed on the key K3, the electronic learning device 1 displays a keyword search screen using the Japanese-English dictionary. Thereby, when the term which wants to translate into English comes out during the learning, the user can easily translate the term into English.

  Thus, the keys K1 to K3 are keys for calling up the dictionary, and when starting the search, any of the keys K1 to K3 is selected. That is, the keys K1 to K3 receive an input operation for starting a search.

  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 example shown in the figure, the name of a dictionary used for keyword search (◯ × Japanese dictionary) is displayed, and a keyword display area A2 and a keyboard K4 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 K4 with the touch pen P or the like. The entered characters are displayed in the keyword display area A2, and by selecting “OK” on the keyboard K4, a search is performed using the entered character string as a keyword.

  In FIG. 5 (b), it is assumed that the user inputs and decides "Compliance", whereby the display as shown in FIG. 5 (c) is performed. In the example shown in the figure, the name of the dictionary used for the keyword search is displayed, and the result of searching “COMPLEANS” in the dictionary is displayed. In addition, a key K5 for ending display of the dictionary search result and returning to the reproduction of the content is also displayed.

  Here, when a touch operation is performed on the key K5, the electronic learning device 1 ends the display of the dictionary search result, and the content is returned only by the content return time before the playback time of the content at the time of pause. The playback time is returned, and the playback of the content is resumed from the playback time. Thereby, the electronic learning apparatus 1 can reproduce | regenerate again the scene from which the term which the user confirmed the meaning comes out after displaying a dictionary search result. Therefore, when a term whose meaning is to be confirmed appears during the reproduction of the content, the user can re-view the scene of the content after confirming the meaning of the term.

  In addition, when such a keyword search is performed, the electronic learning device 1 obtains the reproduction time of the content when the keyword search is started, the dictionary that is the target of the keyword search, and the keyword used for the search. The associated history data 32 is generated and stored.

  Then, the electronic learning device 1 refers to the history data 32 and the display timing correction time included in the setting data 33 next time the content is reproduced, and from the timing when the keyword search has been performed in the past. In addition, the keyword used for the search is displayed at a timing before the display timing correction time. Note that an operation example when displaying a keyword will be described later.

  Next, another 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. 6C shows a keyword. An example of operation after execution of a search is shown. The operation example shown in FIG. 6 is different from the operation example shown in FIG. 5 in the case where the keyword search is performed while reproducing the content without pausing the reproduction of the content during the keyword search.

  The example of FIG. 6A is the same as the example of FIG. 5A, and the image of the content is displayed in the image display area A1, and the keys K1 to K3 are adjacent to the image display area A1. Is displayed.

  Here, when the touch operation is performed on the key K1, the electronic learning device 1 divides the screen of the display unit 11 into two, displays the content image, and reproduces the content while searching for the image. Is displayed. Specifically, the electronic learning device 1 divides the screen of the display unit 11 into two, generates a content display area B1 and a search display area B2, and displays a screen as shown in FIG. 6B. .

  In the illustrated example, the content display area B1 displays an image display area A1 and keys K1 to K3, and the search display area B2 contains the name of a dictionary used for keyword search (◯ × Japanese dictionary). In addition to the display, a keyword display area A2 and a keyboard K4 are displayed.

  In the state shown in FIG. 6B, if “COMPLEANS” is input and a keyword search is performed, a display as shown in FIG. 6C is performed. In the example shown in the figure, the name of the dictionary used for the keyword search is displayed in the search display area B2 while the content is played back in the content display area B1, and the result of the search for “companies” in the dictionary is shown. Is displayed. In addition, the search display area B2 also displays a key K5 for ending the display of the dictionary search result and returning to the reproduction of the content (resuming the reproduction of the content).

  Here, when a touch operation is performed on the key K5, the electronic learning device 1 ends the display of the dictionary search result, and the content return time is earlier than the content reproduction time at the time when the key K1 is input. Then, the reproduction time of the content is returned, and the reproduction of the content is resumed from the reproduction time. Thereby, the electronic learning apparatus 1 can reproduce | regenerate again the scene from which the term which the user confirmed the meaning comes out after displaying a dictionary search result. Therefore, when a term whose meaning is to be confirmed appears during the reproduction of the content, the user can view the content after confirming the meaning of the term.

  Note that the content reproduction may be resumed while the search result is displayed in the search display area B2. In this case, for example, in the state of FIG. 6C, a “search result confirmed” key (not shown) is newly provided in the search display area B2, and the “search result confirmed” key is selected. In the content display area B1, the electronic learning device 1 may resume the reproduction of the content from the content return time before the content reproduction time when the key K1 is input. The electronic learning device 1 also displays the content at the time when the key K1 is input in the content display area B1 while the search result is displayed in the search display area B2 after a certain time has elapsed since the search result was displayed. The playback of the content may be automatically resumed from the playback time before the content return time.

[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. 5A, when no keyword is displayed, the content image is displayed in the image display area A1 and keys K1 to K3 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 that is earlier than the reproduction time stored in the history data 32 by the display timing correction time. If it is confirmed, the keyword associated with the reproduction time after the display timing correction time after the coincident reproduction time is displayed.

  For example, in the example of FIG. 5C, when it is 13 minutes and 15 seconds, which is the display timing correction time before the playback time associated with the keyword “compliance”, as shown in FIG. The key K6 (object) displayed as “compliance” is displayed.

  When the displayed key K6 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 searching the term at the timing when the term appears during the reproduction of the content. This keyword has been previously examined by the user using the dictionary data 31, so if the user remembers the meaning or the like at that time, the search result by the keyword is displayed again. There is no need, and it is desirable to continue playing the content. On the other hand, the user may have forgotten the search result (meaning of the term).

  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 in the history data 32 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, in addition to the key K6 displayed as “Compliance”, a key K7 (object) displayed as “CSR” is displayed. The user can select any of these keys (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, as shown in FIG. 9, the user may 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 K5 displayed as “Close” is displayed and the key (deletion object) K8 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 K8. Thus, the next time the same content is reproduced, the “compliance” keyword is not displayed.

  Note that the timing for displaying the key K8 for deleting history data is not limited to the above example, and the key K8 may be displayed when a keyword is displayed, for example. 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.

[Example of setting data 33 setting screen]
Next, an example of a setting screen when the electronic learning apparatus 1 causes the user to input a content return time will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of a setting screen when the electronic learning device 1 causes the user to input a content return time. Note that the electronic learning device 1 displays the content return time setting screen illustrated in FIG. 10 when receiving an instruction to start the content return time setting process from the user.

  In the example shown in FIG. 10, a character string “content return time” is displayed on the display unit 11, and a content return time display area A3 and keys K9 and K10 are displayed. In the content return time display area A3, the numerical value of the content return time input by the user is displayed.

  If the key K9 “OK” is selected while the content return time value is displayed in the content return time display area A3, the electronic learning device 1 returns the content return included in the setting data 33 of the storage unit 13. The time is set to a numerical value (60 seconds in the illustrated example) displayed in the content return time display area A3, and the content return time setting process is terminated. On the other hand, when “cancel” of the key K10 is selected in the state shown in the drawing, the electronic learning device 1 ends the content return time setting process without updating the setting data 33.

  Next, an example of a setting screen when the electronic learning device 1 causes the user to input the display timing correction time will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of a setting screen when the electronic learning device 1 causes the user to input the display timing correction time. It is assumed that the electronic learning device 1 displays the display timing correction time setting screen shown in FIG. 11 when receiving an instruction to start the display timing correction time setting process from the user.

  In the example shown in FIG. 11, a character string “display timing correction time” is displayed on the display unit 11, and a display timing correction time display area A4 and keys K11 and K12 are displayed. In the display timing correction time display area A4, the numerical value of the display timing correction time input by the user is displayed.

  When “OK” of the key K11 is selected in the state where the numerical value of the display timing correction time is displayed in the display timing correction time display area A4, the electronic learning device 1 is included in the setting data 33 of the storage unit 13. The display timing correction time is set to a numerical value (30 seconds in the illustrated example) displayed in the display timing correction time display area A4, and the display timing correction time setting process is terminated. On the other hand, when “cancel” of the key K12 is selected in the state shown in the drawing, the electronic learning device 1 ends the display timing correction time setting process without updating the setting data 33.

[History data generation processing]
Next, history data generation processing in which the electronic learning device 1 generates the history data 32 will be described with reference to FIG. FIG. 12 is a flowchart illustrating an example of history data generation processing. The history data generation process is a process performed during content reproduction. In the history data generation process shown in FIG. 12, as shown in FIG. 5, when a keyword search is performed during content reproduction, content reproduction is temporarily stopped.

  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 (S1). 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 selection of a dictionary (S2), and when it is confirmed that a dictionary has been selected (YES in S2), the reproduction processing unit 20 pauses the reproduction of content. The process proceeds to (S3) and S4. On the other hand, if it is not confirmed that the dictionary is selected (NO in S2), the process proceeds to S10.

  In S4, the search processing unit 21 displays a keyword input screen on the display unit 11 (S4) and waits for a search to be executed (S5). Note that, for example, since characters to be input change according to the dictionary used for the search, such as English-Japanese dictionary and Japanese-English dictionary, it is preferable to display the keyword input screen according to the dictionary.

  When a keyword is input and a search execution instruction is input, the search processing unit 21 searches the keyword in the dictionary selected in S2 and displays the search result on the display unit 11 (S6). In addition, the search processing unit 21 notifies the history data generation unit 22 of the keyword and dictionary used for the search.

  Upon receiving the keyword and dictionary 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 S3, the acquired playback time, and the search processing unit. The history data 32 is generated by associating the keyword and the dictionary notified from 21 and stored in the storage unit 13 (S7).

  On the other hand, the search processing unit 21 displaying the search result in S6 confirms whether or not to end the display of the search result (S8). Here, when it is confirmed that the display of the search result is finished (YES in S8), the search processing unit 21 instructs the reproduction processing unit 20 to resume the reproduction of the content. Receiving the instruction, the playback processing unit 20 starts playback of the content from the playback time that is the content return time before the playback time at which the currently playing content is paused. 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 (S9).

  The reproduction processing unit 20 that has resumed the reproduction confirms whether or not to end the reproduction of the moving image (S10). If it is confirmed that the reproduction is not terminated (NO in S10), the process returns to S2. On the other hand, when it is confirmed that the moving image reproduction is to be ended (YES in S10), the process proceeds to S11, and the reproduction processing unit 20 ends the reproduction of the moving image, thereby ending the history data generation process.

  Note that 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 receives an input operation to terminate the reproduction.

[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. 13 is a flowchart illustrating an example of the keyword display process. Similar to the history data generation process, the keyword display process is also 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 and displays only the display timing correction time from the current reproduction time of the content and the reproduction time stored in the history data 32. Whether there is a match with the previous reproduction time is checked (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 matches the playback time in the history data 32 by a display timing correction time after the current video data playback time. The keyword associated with the reproduction time to be identified is specified. 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, it is determined that the display of the search result is ended when the key K8 is selected (YES in S28) and recorded. Is determined to be deleted (YES in S29). On the other hand, when the key K5 is selected in the screen example of FIG. 9, it is determined that the display of the search result is finished (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 K5 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.

[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.

  Here, an example of an electronic learning system that causes another device to execute a keyword search will be described with reference to FIG. FIG. 14 is a block diagram showing a main configuration of the electronic learning device (content reproduction device) 40 and the server 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, the search processing unit 21 is replaced with a search processing unit (search means, search result display unit) 24, The difference is that the dictionary data 31 is not stored in the storage unit 13.

  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 search processing unit 24 causes an external device (here, the server 50) to execute a search using a keyword and displays the result. Specifically, the search processing unit 24 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.

  The server 50 is a device that performs a keyword search in accordance with an instruction from the electronic learning device 40 and transmits the result to the electronic learning device 40. 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 via a communication network.

  The server control unit 52 controls the operation of the server 50 in an integrated manner, and the server control unit 52 includes a server search processing unit 54. The server search processing unit 54 performs keyword search according to instructions from 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 dictionary data 31.

  According to the electronic learning system 60 described above, when the user of the electronic learning device 40 performs an input operation for performing a keyword search during the reproduction of content, the search processing unit 24 inputs a keyword for causing the keyword to be input. The screen is displayed on the display unit 11.

  When the user inputs a keyword and performs an input operation to execute the search, the search processing unit 24 uses the input keyword, information for specifying a dictionary to be searched with the keyword, and the keyword. A search execution instruction is transmitted to the server 50 via the communication unit 14.

  In the server 50 that has received these information and instructions, the server search processing unit 54 specifies the dictionary specified by the received information from the dictionary data 31 and searches for the keyword received from the electronic learning device 40 using the specified dictionary. I do. Then, the search result is transmitted to the electronic learning device 40 via the server communication unit 51.

  In the electronic learning device 40 that has received the search result, the search result received by the search processing unit 24 is displayed on the display unit 11 so that the user can recognize the search result.

[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 shown in the example of FIG. 14, when searching in an external database, it is expected that re-searching will take time. Therefore, the search result may be stored in the electronic learning device 40. preferable.

[Search target database]
In the above description, an example in which a keyword is searched in any one of three databases, a national language dictionary, an English-Japanese dictionary, and a Japanese-English dictionary, has been described, but the database used for the search is not limited 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.

[Modification of configuration for displaying keywords]
In the above description, the keyword display processing unit 23 specifies the keyword display timing based on the reproduction time at the time of keyword search included in the history data 32 and the display timing correction time included in the setting data 33. The method for specifying the keyword display timing is not limited to this.

  For example, instead of the reproduction time of the history data 32, “keyword display time” may be stored. That is, the history data generation unit 22 calculates the playback time before the display timing correction time from the playback time of the content when the keyword search is performed when the history data 32 is generated, and uses this playback time as the “keyword display time”. May be included in the history data 32.

  When the history data generation unit 22 generates the history data 32 including the keyword display time, the keyword display processing unit 23 refers to the history data 32 and displays the content reproduction time and the history data 32 when reproducing the content. Check if there is a match with the stored keyword display time. Then, the keyword display processing unit 23 specifies the keyword associated with the keyword display time that matches the reproduction time of the current content in the history data 32, and displays the specified keyword on the display unit 11.

  The history data generation unit 22 may generate history data 32 including both the content reproduction time when the keyword search is performed and the keyword display time.
