Description

  The present invention relates to a data reproduction apparatus and a data reproduction method, and more specifically, even when digital content (including text data) to be reproduced is operated by a user other than a reproduction operation such as a fast-forward operation. The present invention relates to a data reproduction apparatus and a data reproduction method that make it possible to determine that a digital content whose content has been substantially confirmed by a user has been read.

  A data playback device that outputs digital content stored in a storage unit arranged on the main unit or on a network (on the so-called cloud) to a display unit or an audio output unit has a configuration adapted to the intended use of the user Many are provided. As an example of such a data reproducing apparatus, a DAISY reproducing apparatus in which digital content is generated in accordance with the DAISY (Digital Accessable Information System) standard is known.

  The DAISY playback device is suitably used as a learning support device for children who are difficult to read and students (hereinafter referred to as users). Some DAISY playback devices proposed by the applicant have a function of collecting a user's operation history log for digital content (see Patent Document 1). In recent years, an attempt has been made to grasp the learning status of the user by analyzing the contents of the user's operation history log collected by the DAISY playback device.

Japanese Unexamined Patent Publication No. 2007-164776

  According to the DAISY playback apparatus capable of collecting such user operation history logs, since it is possible to determine that the digital content that the user has performed playback has already been read, The digital content that has been read (reproduced) and the digital content that has not been read (unreproduced) can be easily distinguished, which is convenient in understanding the learning status of the user. However, when displaying the digital content on the screen as the display unit, the user displays the digital content on the screen and confirms the content of the text data of the digital content without outputting the audio data to the audio output unit. After that, a fast-forward operation (confirmation of the contents of the digital content only by screen display (so-called digital content silent reading)) may be performed. As for the digital content that the user has read silently in this way, although the user recognizes that it has been played, it can detect that the playback has been performed even after analyzing the user's operation history log. The whereabouts of new issues that can not be made clear.

  Therefore, the present invention is effective even when the user has not performed a normal reproduction operation (an operation to display text data on the display unit and output audio data to the audio output unit) on the digital content. The purpose of the present invention is to provide a data reproduction apparatus and a data reproduction method that can determine whether or not a digital content is already read when the content of the digital content is confirmed (silently reading the digital content) It is said.

  As a result of inventor's earnest research to solve the above problems, the digital content when the user searches for a phrase (meaning a unit of division in a sentence such as a phrase, a single sentence, or a plurality of sentences) in the digital content. Between the actual display time (digital content residence time) on the display unit for each phrase of the phrase, the display time of the digital content when silently reading the digital content, and the standard display time when the digital content is normally played back Paying attention to the difference, we came up with the following configuration.

  That is, the present invention provides a display unit that displays the text data of digital content including text data, an audio output unit that outputs the content of the text data by voice, and the text data is actually displayed for each phrase in the display unit. A substantial display time storage unit that stores the displayed display time as a substantial display time for each phrase, a standard display time storage unit that previously stores a standard display time for each phrase of the text data, and the substantial Multiplying the actual display time taken out from the display time storage unit and the standard display time corresponding to the real display time taken out from the standard display time storage unit by a predetermined threshold, and from the real display time storage unit The extracted actual display time corresponds to the actual display time extracted from the actual display time storage unit. A read determination unit that determines that the phrase corresponding to the substantial display time is read regardless of the presence or absence of voice output to the voice output unit when the display time is equal to or longer than the time obtained by multiplying the predetermined threshold. And a data reproducing apparatus characterized by comprising:

  As a result, even if the user does not perform normal playback operations on the digital content, if the content of the phrase in the digital content is substantially confirmed (read silently), The already-read determination can be performed on the phrase of the digital content.

  Further, a unit sounding time data storage unit storing standard reproduction time per phoneme of the text data as unit sounding time data, and a phoneme structure for each phrase in the text data are stored as phrase phoneme structure data. The phrase phoneme composition data storage unit, the unit pronunciation time data retrieved from the unit pronunciation time data storage unit, and the phrase phoneme composition data retrieved from the phrase phoneme composition data storage unit are multiplied by the standard display. It is preferable to further include a standard display time calculation unit that calculates time.

  Further, among digital contents including text data, a data output process for outputting at least the text data to a display unit, and a display time during which the text data is actually displayed for each phrase in the display unit, for each phrase A substantial display time storage step for storing the substantial display time in the substantial display time storage unit, the substantial display time is extracted from the substantial display time storage unit, and a standard display time for each phrase of the text data is stored in advance. Taking out the standard display time corresponding to the substantial display time from the standard display time storage unit and multiplying the standard display time by a predetermined threshold, and the substantial display time taken out from the substantial display time storage unit, The standard display time corresponding to the substantial display time taken out from the substantial display time storage unit An invention as a data reproduction method, further comprising: a read determination step that determines that the phrase corresponding to the substantial display time is read when the time is equal to or longer than a time multiplied by the predetermined threshold. is there.

  As a result, even if the user does not perform normal playback operations on the digital content, if the content of the phrase in the digital content is substantially confirmed (read silently), The already-read determination can be performed on the phrase of the digital content.

  A step of retrieving the unit sounding time data from a unit sounding time data storage unit in which a standard reproduction time per phoneme of the text data is stored as unit sounding time data; and a phoneme configuration for each phrase in the text data Extracting the phrase phoneme configuration data from the phrase phoneme configuration data storage unit stored as phrase phoneme configuration data, the unit pronunciation time data extracted from the unit pronunciation time data storage unit, and the phrase phoneme configuration data storage unit It is preferable to further include a standard display time calculation step of calculating the standard display time for each phrase by multiplying the phrase phoneme configuration data extracted from the phrase.

  Moreover, it is preferable that the threshold value can be changed. Thereby, the already-read determination of the digital content according to the user's text reading skill can be performed.

  The unit sounding time data is preferably changeable. This makes it possible to adjust the standard display time for each phrase of the digital content according to the age of the user.

  By adopting the configuration of the data reproducing apparatus and the data reproducing method according to the present invention, the content of the phrase of the digital content is substantially obtained even when the user does not perform the normal reproducing operation on the digital content. Can be determined for the phrase of the digital content. Thereby, the instructor who gives guidance to the user can more accurately grasp the learning status of the user of the data reproducing apparatus and can perform appropriate learning guidance.

  Embodiments of a data reproducing apparatus and a data reproducing method according to the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic configuration diagram of a data reproducing apparatus according to the present embodiment, and FIG. 2 is a flowchart of a data reproducing method by the data reproducing apparatus according to the present embodiment. In the present embodiment, as shown in FIG. 1, a description will be given based on a form in which a data reproducing apparatus 10 is configured by an electronic device called a so-called tablet terminal or slate personal computer. The digital content DC of the data reproducing apparatus 10 is stored in the storage unit 12 typified by a nonvolatile memory composed of a semiconductor or the like. When the data reproducing apparatus 10 has the network connection unit 14, the digital content DC stored in the storage unit 30 provided on the network connected via the network connection unit is downloaded or streamed. For example, the storage unit 12 may be used by permanently or temporarily storing it. In this case, the storage unit 12 may be a volatile memory. Further, the connection form of the network connection unit 14 may be any type of wired connection / wireless connection.

  Note that the digital content DC in the present embodiment refers to digital data including at least sound data obtained by reading out text data and text data. It is also possible to include other data such as image data in addition to text data and audio data.

  The digital content DC stored in the storage unit 12 is read from the storage unit 12 by the operation control unit 18 (data reading process). The digital content DC read from the storage unit 12 is represented by a display unit 16A represented by a liquid crystal screen of the data reproducing apparatus 10 and displaying text data and image data, and an audio output unit 16B represented by a speaker and outputting audio data by voice. The data is output to the configured data output unit 16 (data output process). The operation control unit 18 typified by the CPU of the data reproduction apparatus 10 causes the data output unit 16 to sequentially output the digital content DC based on the reproduction program PP installed in the storage unit 12 in advance.

  The operation control unit 18 also has a function as a phrase reproduction log collection unit 18A. When the text data of the digital content DC is output to the display unit 16A, the phrase reproduction log collection unit 18A determines the time (display start time OT) when each phrase in the text data is actually displayed on the display unit 16A. Collected and stored in the storage unit 12. The phrase reproduction log collection unit 18A collects the operation contents OP of the user within the display time of the phrases on the display unit 16A in the text data of the digital content DC and stores them in the storage unit 12 as the phrase reproduction log FL. . Here, the process of collecting the display start time OT and the operation content OP for each phrase is a phrase reproduction log collecting process. The storage unit 12 as a standard time storage unit stores a standard display time NT for each phrase in the text data of the digital content DC.

  Then, the phrase reproduction data creating unit 18B has an identification number ID and a standard display time NT given to each phrase in the text data of the digital content DC registered in the reproduction program PP, and a display start time OT of the phrase reproduction log FL. Then, the phrase reproduction data FP (see FIG. 3) associated with the operation contents OP is created (phrase reproduction data creation step), and the created phrase reproduction data FP is stored in the storage unit 12 (phrase reproduction data storage) Process). In addition to the above information, the phrase reproduction data FP can be associated with other information related to phrase reproduction to the phrase identification number ID.

  Here, a method of collecting the substantial display time RT on the display unit 16A for each phrase of the text data of the digital content DC by the substantial display time calculation unit 18C in the present embodiment will be described. The substantial display time calculation unit 18C calculates the difference between the display start time OT of the Nth phrase of the text data of the digital content DC and the display start time OT of the (N + 1) th phrase from the phrase reproduction data FP. The substantial display time RT of the Nth phrase is obtained (actual display time calculation step). Then, the substantial display time calculation unit 18C stores the substantial display time RT of the Nth phrase in the storage unit 12 which is a substantial display time storage unit (substantial display time storage step). Here, when automatic playback or normal playback operation is performed by the playback program PP, the actual display time RT in the Nth phrase of the digital content DC is the standard display time NT in the Nth phrase of the digital content DC. Is equal to.

  In response to the normal reproduction operation of the digital content DC, after a phrase in the text data of the digital content DC is output to the display unit 16A, the user performs a sending operation or a return operation on the displayed phrase. In this case, the actual display time RT for the phrase is shorter than the standard display time NT for the phrase. More specifically, when the user is searching for a phrase in the digital content DC to be output, the actual display time RT is almost much shorter than the standard display time NT.

  Even when the user performs a sending operation or a return operation on a specific phrase of text data of the digital content DC, the user performs so-called silent reading or the like on the specific phrase (text of the digital content DC It is also conceivable that the content of the specific phrase in the data has been sufficiently confirmed). In such a case, the substantial display time RT corresponding to the specific phrase may be shorter than the standard display time NT corresponding to the specific phrase, but may not be extremely short. It has become clear from the experimental results (see FIG. 4).

  In the present embodiment, the read determination unit 18D realized by the operation control unit 18 confirms the content of the phrase for the Nth phrase of the text data of the digital content DC based on the phrase reproduction data FP ( It is determined whether or not (read). For this determination, as shown in FIG. 5, the read determination unit 18D compares the standard display time NT with a predetermined threshold value TH stored in the storage unit 12 and the actual display time RT. Is done.

  Specifically, in the read determination unit 18D, the substantial display time RT in the Nth phrase of the text data of the digital content DC is equal to or longer than the time obtained by multiplying the standard display time NT in the Nth phrase by the threshold value TH. In this case, the Nth phrase is determined as being read regardless of whether audio data of the digital content DC is output, and the actual display time RT in the Nth phrase of the text data of the digital content DC is in the Nth phrase. If it is less than the time obtained by multiplying the standard display time NT by the threshold value TH, the Nth phrase is determined to be unread regardless of whether or not the audio data of the digital content DC is output (read determination step). The read determination unit 18D creates the read determination data JD in which the result of the read or unread determination performed as described above is associated with the identification number ID of the phrase and is a storage determination data storage unit 12 is stored (read determination data storage step). An identifier for the digital content DC and the text data in the digital content DC can be given to the read determination data JD.

  The threshold TH is a data input unit (not shown) output to the display unit 16A by the playback program PP before the read determination unit 18D performs the read determination process for each phrase of the text data of the digital content DC. Can be used, or can be stored in advance in the storage unit 12 according to the user's age, silent reading skill, or the like. The threshold value TH may be set so as to be changeable from a numerical value previously input by the data input unit or a numerical value previously stored in the storage unit 12 to a new numerical value input by the data input unit (threshold change). Process).

  The already-read determination unit 18D can confirm from the phrase reproduction data FP that the specific phrase of the text data of the digital content DC has been automatically reproduced or that the user has performed a reproduction operation. Can skip (omit) the already-read determination process for the phrase.

  As described above, the data reproduction device 10 according to the present embodiment determines whether each digital content DC registered in the reproduction program PP is read or unread for each phrase in the text data in the digital content DC. The already-read determination data JD for determination can be stored in the storage unit 12. The user's instructor activates the management software stored in advance in the storage unit 12 of the data reproducing apparatus 10, and the operation control unit 18 uses the already-read determination data JD on the display unit 16A based on the management software. The learning situation of the user can be graphed and output. Thus, the instructor can accurately determine the reproduction state of the digital content DC by the user data reproduction device 10 based on the read determination data JD obtained from the data reproduction device 10 used by the user. This is advantageous in that it makes it possible to perform appropriate learning guidance according to the learning situation of the user.

(Second Embodiment)
Of the configuration of the data reproducing apparatus 10 in the present embodiment, the same components as those in the data reproducing apparatus 10 in the first embodiment will be described in detail by using the reference numerals used in the first embodiment. Is omitted. As shown in FIG. 6, the data reproducing apparatus 10 according to this embodiment includes a storage unit 12 as a unit sounding time data storage unit as a standard sounding time data TD as a standard sounding time per phoneme in text data of digital content DC. Is stored in advance. Further, the phoneme configuration for each phrase in the text data of the digital content DC is stored in advance in the storage unit 12 as the phrase phoneme configuration data storage unit as the phrase phoneme configuration data FD. The phrase phoneme configuration data FD in the present embodiment is data on the number of phonemes included in each phrase. In addition, a standard display time calculation unit 18E is provided in the operation control unit 18.

  The standard display time calculation unit 18E extracts the unit pronunciation time data TD and the phrase phoneme configuration data FD from the storage unit 12 (unit pronunciation time data extraction step, phrase phoneme configuration data extraction step). Further, the standard display time calculation unit 18E calculates the standard display time NT for each phrase in the text data of the digital content DC by multiplying the unit pronunciation time data TD and the phrase phoneme configuration data FD (standard display time calculation). (Step) and the storage unit 12 as a standard display time storage unit (standard display time storage step). Using the standard display time NT for each phrase, the substantial display time RT, and the threshold value TH calculated in this way, the already-read determination unit 18D can perform the already-read determination for each phrase in the same manner as in the previous embodiment. .

  When such a configuration of the data reproducing apparatus 10 is adopted, it is not necessary to associate the standard display time NT in advance for each phrase in the text data of the digital content DC, and the data reproducing apparatus 10 has a TTS function. If so, the audio data of the digital content DC can be omitted, and the data capacity of the digital content DC can be reduced. The user's instructor can also change the numerical value of the unit sounding time data TD via the input means (not shown) displayed on the display unit 16A by the reproduction program PP (change the unit sounding time data). Process). Thus, the instructor can set the data reproducing apparatus 10 according to the user's text-to-speech reading skill without performing a process of greatly replacing the digital content DC stored in the storage unit 12 of the data reproducing apparatus 10. It is convenient in that it can.

  The data reproducing apparatus 10 and the data reproducing method using the same according to the present invention have been described in detail above based on the embodiments. However, the technical scope of the present invention is not limited to the above embodiments. Absent. For example, in the above embodiment, the phrase control log collecting unit 18A, the phrase playback data creation unit 18B, the substantial display time calculation unit 18C, and the already-read determination unit 18D are performed by the operation control unit 18 built in the data playback device 10. However, the present invention is not limited to this embodiment. Specifically, a form as a data reproduction state determination system 100 as shown in FIG. 7 can be adopted.

  The data reproduction state determination system 100 is a reproduction state determination system 100 that includes the data reproduction apparatus 10 in which some functions of the data reproduction apparatus 10 in the above embodiment are omitted, and a personal computer 50 that substitutes for some functions that are omitted. It is an embodiment. Since the personal computer 50 has a well-known configuration, a detailed description thereof is omitted here. As shown in FIG. 7, the data reproducing apparatus 10 and the personal computer 50 are connected so as to be capable of data communication via a network connection unit 14 or a hardware interface (not shown). The data reproducing apparatus 10 here has a configuration limited to the function that causes the phrase reproduction log collecting unit 18A to execute the process up to the data reproduction log storage step. Further, in a storage unit (not shown) of the personal computer 50, a phrase reproduction data creation unit 18B, a substantial display time calculation unit 18C, and a read determination unit 18D (and a standard display time calculation unit 18E) are connected to a CPU (not shown) of the personal computer 50. Application software to make it function is installed.

  In the second embodiment, the standard playback time per phoneme is the same regardless of the characters, and the phrase phoneme configuration data FD is the number of phonemes included in the phrase. is there. As a modification of the second embodiment, unit sounding time data TD obtained by associating a standard reproduction time per phoneme with different times according to characters, and the number of characters and characters included in each phrase It is also possible to adopt an embodiment using phrase phoneme configuration data FD linked with.

  Further, in the above embodiment, whether or not the substantial display time RT in a specific phrase in text data of a certain digital content DC is equal to or longer than the time obtained by multiplying the standard display time NT corresponding to the same phrase by the threshold value TH. As described above, the description has been given of the form of performing the read determination (determining that the threshold value TH is less than 1) for determining whether the phrase in the text data of the digital content DC is read or not. It is not something. For example, the threshold TH is set to a numerical value greater than 1, and the actual display time RT in a specific phrase in text data of a certain digital content DC is equal to or longer than the time obtained by multiplying the standard display time NT corresponding to the same phrase by the threshold TH. Depending on whether or not, it is possible to adopt a usage form for determining the degree of difficulty in reading a specific phrase of text data of the digital content DC by the user.

  In the case of such usage, if the total reproduction frequency data is additionally linked to the phrase identification number ID for each phrase of the text data of the digital content DC in the phrase reproduction data FP, more detailed digital content by the user It is possible to analyze the degree of difficulty in reading for each phrase in the DC text data. Further, in the form of analyzing the degree of difficulty in reading for each phrase in the text data of the digital content DC, the case where the text data of the digital content DC is left on the display unit 16A while being displayed for each phrase is excluded. Therefore, it is more preferable to set an upper limit value for the threshold value TH.

Further, in the above embodiment, the actual display time RT for each phrase in the text data of the digital content DC is described in the form of calculating the difference in reproduction start time between the Nth phrase and the (N + 1) th phrase. However, the Nth and (N + 1) th are not necessarily the display order of the phrases registered in the text data, but the phrases actually displayed on the display unit 16A of the data reproducing apparatus 10 by the user's operation. It may be in order. Such a form corresponds to the case where the user is silently reading the phrase of the text data in the digital content DC in the return direction.
And it is also possible to employ | adopt the form which combined the form demonstrated in the above embodiment and the said modification suitably.
