FIG. 1 shows the overall configuration of an education support system according to the present invention.
The education support system 20 includes one or more server devices 30 and one or more terminal devices 40. In FIG. 1, a plurality of terminal devices 40 are connected to one server device 30 via a network 21 such as the Internet.

In the education support system 20, each learner owns at least one terminal device 40. Each terminal device 40 downloads learning digital content from the server device 30, and each learner uses the learning device for learning. It is for viewing digital content. As a digital content for learning, an electronic book according to the DAISY standard is adopted. When the learner operates the terminal device 40 to reproduce the learning digital content, the sentence portion of the learning digital content is displayed on the terminal device and the terminal device reads out the voice data corresponding to the displayed sentence portion. To work.
The server device 30 can be operated by a person who is in a position to bundle learners, such as a learner's instructor or teacher.

Based on FIG. 2 which shows the structure of the terminal device 40, the terminal device 40 is demonstrated.
The terminal device 40 can employ a tablet terminal (slate PC) that is a portable terminal that can be connected to the Internet.
The terminal device 40 includes a display unit 41 that employs a touch panel, an interface unit 42 for connecting to the Internet, a control unit 44 that includes a CPU, a memory, and the like, and a speaker 47 that outputs sound. The terminal display unit in the claims corresponds to the display unit 41 described above. Further, the above-described speaker 47 corresponds to the sound output unit in the claims.

  The terminal device 40 includes playback software A that plays back digital content stored in the server device 30. The reproduction software includes a program having a function capable of reproducing digital content downloaded from the server device 30 (including streaming reproduction for reproduction while downloading). The reproduction software A is stored in a storage unit 46 such as a semiconductor memory, and the control unit 44 reads out and executes the reproduction software A to reproduce digital content.

  The terminal device 40 can set reproduction time setting information including at least a character format, a character color, and an audio output condition. The digital content is reproduced based on the reproduction setting information. More specifically, the setting information at the time of reproduction includes a typeface of the character, a size of the character, an audio reproduction speed, and the like.

The terminal device 40 has a playback condition setting unit 49 that can set the playback time setting information by an operator (learner) of the terminal device 40 and execute display of digital contents and audio output under the set conditions. ing.
The reproduction condition setting unit 49 is provided not only for the operator (learner) of the terminal device 40 but also for the server device 30. That is, the operator (instructor) of the server device 30 can perform playback settings suitable for each learner, and the learning effect can be improved.

The digital content in this embodiment is assumed to be an electronic book. As a standard for electronic books, the DAISY standard, which is a digital recording book, is typical.
Electronic book data of the DAISY standard includes a smil (Synchronized Multimedia Integration Language) file, an ncc file or ncx file in which header information is described, an html file or xml file in which text data that can be displayed on the display unit 41 is described, And an audio data file that reads out the text data.

  The smil file is a kind of markup language, and describes the display order of each phrase in the html file or xml file, and the playback start / end time of the audio data file corresponding to each phrase.

  In the terminal device 40, when the control unit 44 executes the reproduction software A, text data is displayed on the display unit 41 for each phrase of predetermined digital content. In addition, when the operator (learner) of the terminal device taps a play button 50 described later, the audio data file corresponding to the text data displayed on the display unit 41 is synchronized with the text data and the speaker 47. Audio output.

As the reproduction software A is executed, a screen as shown in FIG. 3 is displayed on the display unit 41 of the terminal device 40, for example.
In the example shown in this figure, a part of a sentence in the digital content is displayed from right to left. Also, a play button 50, a fast forward button 52, a rewind button 54, a next page button 56, and a previous page button 58 are displayed below the sentence.

  Since the display unit 41 is a touch panel, the operator (learner) can select any one of the playback button 50, the fast forward button 52, the rewind button 54, the next page button 56, the previous page button 58, or the phrase he wants to hear. The reproduction software A executes each operation by directly tapping.

For example, when the operator (learner) taps the playback button 50, the playback software A plays back an audio data file corresponding to the text displayed on the display unit 41.
When the reproduction of the audio data file ends, the operator (learner) can reproduce the same phrase again by tapping the rewind button 54 if the understanding does not proceed.
When proceeding to the next page, the playback software causes the display unit 41 to display the text of the next phrase by tapping the next page button 56.

  When the audio data file is reproduced, the phrase ID information and the reproduction start time for each phrase are stored in the storage unit 46 as reproduction log data. Other examples of the reproduction log data include date and time, operation information operated on the terminal device 40 (operations such as a reproduction button and a stop button), reproduction information (contents of the phrase), setting value change information from the server device 30, and the like. Also includes data including

The playback software can also handle pinch-in and pinch-out. When the operator (learner) pinches in, the reproduction software reduces each character displayed on the display unit 41 and displays more characters. Therefore, the number of display characters per screen increases.
On the other hand, when the operator (learner) pinches out, the reproduction software enlarges each character displayed on the display unit 41 and reduces the number of characters displayed. Therefore, the number of display characters per screen is reduced.

  The playback time for each screen varies with pinch-in or pinch-out, but the playback log data includes the first and last phrases displayed on the screen along with the playback time for each phrase. By storing as a log, a pinch-in or pinch-out operation can be recorded. Similarly, scrolling operations can be recorded.

The reproduction log data stored in the storage unit 46 is collectively transmitted to the server device 30 after the reproduction of one learning digital content is completed. The reproduction log data may be transmitted at the reproduction end timing as the reproduction log data transmission timing.
However, the reproduction log data may be transmitted to the server device 30 by transmitting reproduction log data for each phrase every time detection of the reproduction time in one phrase is completed.

Next, the configuration of the server device 30 is shown in FIG.
The server device 30 can employ a general computer (PC). The server device 30 includes a storage unit 60 configured by an HDD or the like, an interface unit 62 for connecting to the Internet, a control unit 64 configured by a CPU and a memory, and a display unit 63 configured by a monitor and the like. And an input unit 65 including a mouse and a keyboard.

  The server display unit in the claims corresponds to the display unit 63, the reception unit in the claims corresponds to the interface unit 62, and the display control unit in the claims includes the above-described display unit. The control unit 64 implements display software to be described later.

In the server device 30, the reproduction log data transmitted from each terminal device 40 is received by the interface unit 62 and stored in the storage unit 60.
The control unit 64 of the server device 30 converts the reproduction log data (including at least the ID information for each phrase and the reproduction start time for each phrase) stored in the storage unit 60 into the number of reproductions for each phrase. Therefore, the control unit 64 of the present embodiment corresponds to a data conversion unit referred to in the claims.

Here, the structure of the reproduction log data is shown in FIG.
The reproduction log data generated in each terminal device 40 includes the date and time when some operation button is operated, the content of the operation, the state of the terminal device 40, the title name, the reproduction file name, the phrase ID, and the text data of the corresponding phrase. It is.
The control unit 64 calculates the number of times of reproduction of each phrase from the reproduction log data as described above, based on how many identical file names exist for the file name for each phrase.

  Then, the control unit 64 changes the character setting of the digital content stored in the storage unit 60 based on the number of times of reproduction of each phrase calculated from the reproduction log data, and sets the character setting on the display unit 63. Display the changed digital content. The display software B executes the display of the digital content whose character setting is changed according to the number of times of reproduction. The control unit 64 of the present embodiment corresponds to a display control unit in the claims.

FIG. 6 shows an example of digital content displayed on the display unit.
In the case of the example shown in FIG. 6, the control unit 64 changes the background color of the digital content character read from the storage unit 60 for each number of playbacks, and displays the changed digital content on the display unit 41.

In the example of FIG. 6, the number of times of reproduction is 0, 1, 2, 3, 4 or more, and the control unit 64 has no background color for the phrase of 0 times of reproduction. The background color is set from light to dark as the number of playbacks increases.
When the number of times of reproduction is four times or more, the background color becomes very dark, so the characters are made white to prevent the characters from becoming inconspicuous in the background color and becoming unreadable.

Note that a browser may be used as the display software B. By using a browser, the storage unit 60 needs to store digital content in a markup language such as html or xml.
When changing the background color in each calculated phrase, the control unit 64 can change the background color by changing the tag of the corresponding part in the markup language describing the digital content.
In this way, by using the display software B as a browser, it is often installed in a normal personal computer or the like in advance, and the setting of characters of digital contents can be easily changed.

In the example of FIG. 6, the control unit 64 changes the background color of the character of the corresponding phrase from a light color to a dark color as the number of reproductions increases. As the number increases, the background color of the characters of the corresponding phrase may be changed from warm to cold. Thus, even if the background color is changed, the number of reproductions can be easily identified.
Further, the control unit 64 may change the background color of the character with the shade of the same system color, and may adopt a different system color as the background color of the phrase of any number of reproductions.

Furthermore, the setting change of the character in each phrase based on the number of times of reproduction is not limited to changing the background color.
For example, the control unit 64 may change the size of characters. In this case, what is necessary is just to change so that a character may become large as the frequency | count of reproduction | regeneration increases.
Further, the control unit 64 may change the color of the character itself. In this case, it is conceivable to change the character color darker as the number of times of reproduction increases, or from warm color to cold color.

It should be noted that the change in the digital content character setting based on the number of reproductions described above is not based on one piece of reproduction log data, but may be based on the total number of reproductions in a plurality of pieces of reproduction log data.
That is, when the same unit is learned a plurality of times, a plurality of reproduction log data is generated, but the learning history of the entire unit can be grasped from a comprehensive view based on the number of reproductions obtained by collecting the results of learning a plurality of times.
Note that even if the same unit is learned multiple times, it is not the total number of playbacks, but one or more playback log data is selected from the multiple times and the character setting of the digital content is changed. May be.

When one or a plurality of reproduction log data is generated, the control unit 64 selects a range (for example, a date and a phrase) designated by the operator, and a selected portion of the one or a plurality of reproduction log data. May be added, and the character setting may be changed based on the added number of reproductions.
As described above, by specifying the date and time range, adding the number of playbacks of the playback log data, and changing the character settings based on this, it is possible to grasp the learning history within a predetermined period from a bird's-eye view it can. In addition, by selecting the phrase and adding the number of playbacks of the selected phrase in the playback log data, and changing the character settings based on this, the learning history of a specific phrase can be seen from a bird's-eye view. .

Next, an example in which the terminal device 40 itself performs display as shown in FIG. 6 will be described.
The configuration of the terminal device 40 in this case is shown in FIG. In addition, about the component same as the component mentioned above, the same code | symbol is attached | subjected and description may be abbreviate | omitted.

  The control unit 44 of the terminal device 40 calculates the number of reproductions of each phrase from the reproduction log data stored in the storage unit 46 based on how many identical file names exist for the file name for each phrase.

  Then, the control unit 44 changes the character setting of the digital content stored in the storage unit 46 based on the number of reproductions of each phrase calculated from the reproduction log data, and sets the character setting on the display unit 41. Display the changed digital content. The display of the digital content with the character setting changed according to the number of reproductions is executed by the display software B, and the same content as that shown in FIG. 6 is displayed. The control unit 44 of the present embodiment corresponds to a display control unit in the claims.

Note that a browser may be used as the display software B. By using a browser, the storage unit 46 needs to store digital content in a markup language such as html or xml.
When the background color in each calculated phrase is changed, the control unit 44 can change the background color by changing the tag of the corresponding part.
As described above, by using the display software B as a browser, it is often preinstalled in a normal tablet or the like, and the setting of characters of digital contents can be easily changed.

Also in the terminal device 40, the change of the digital content character setting depending on the number of times of reproduction may be based on the total number of times of reproduction in the plurality of reproduction log data, not based on one piece of reproduction log data. .
That is, when the same unit is learned a plurality of times, a plurality of reproduction log data is generated, but the learning history of the entire unit can be grasped from a comprehensive view based on the number of reproductions obtained by collecting the results of learning a plurality of times.
Note that even if the same unit is learned multiple times, it is not the total number of playbacks, but one or more playback log data is selected from the multiple times and the character setting of the digital content is changed. May be.

  When one or a plurality of reproduction log data is generated as described above, the control unit 44 selects a range (for example, date and phrase) designated by the operator, and selects the selected portion of the reproduction log data. The number of reproductions may be added, and the character setting may be changed based on the added number of reproductions.

  The above-described embodiments have been described for reproducing recorded audio data. However, it is also possible to employ a text to speech (TTS) system that has no recorded voice data and converts text data to voice data. However, when employing the TTS system, it is necessary to provide a control unit having a TTS function in the terminal device 40.

  While the present invention has been described above with reference to a preferred embodiment, the present invention is not limited to this embodiment, and it goes without saying that many modifications can be made without departing from the spirit of the invention. .
