Description

[Technical field]

[0001] The present invention relates to an electronic device, a learning level estimation method, and a program. [Background technology]

[0002] Slash reading is one method of learning English. Slash reading is known to be effective in training the user to understand the meaning of a sentence in English without changing the word order. However, many of the long-text contents of current electronic dictionaries are equipped with natural Japanese translations for each sentence or paragraph, but are unable to display Japanese translations for each phrase, making learning through slash reading difficult.

[0003] On the other hand, technology has been proposed to realize learning through slash reading in conjunction with video and audio, using general English movies, dramas, anime, etc. as learning materials and devices (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0008] The learning level estimation method of the present invention is a learning level estimation method for estimating the learning level of a user who is reading a text, and is characterized in that it includes the steps of: when a position before or after a word contained in the text is selected based on a user operation, displaying a delimiter symbol on a display unit at the selected position; acquiring information regarding the displayed delimiter symbol; and estimating the user's learning level based on the acquired information regarding the delimiter symbol.

[0009] The program of the present invention is a program to assist a user in learning to read and understand text, and is characterized by having the following features: a display control function that causes a delimiter to be displayed on the display unit at a location before or after a word contained in the text when the location is selected based on user operation; an acquisition function that acquires information regarding the delimiter displayed by the display control function; and an estimation function that estimates the user's learning level based on the information regarding the delimiter acquired by the acquisition function.

[0012] A. Configuration of the embodiment The best mode for carrying out the present invention will be described below with reference to the drawings. However, the embodiment described below is provided with various limitations that are technically preferable for carrying out the present invention, and the scope of the invention is not limited to the following embodiment and illustrated examples. In the following description, the "delimiter" is defined in the foreign language text using terms such as "input (setting)" and "display", and both expressions mean that the phrase position in the foreign language text corresponds to the position of the delimiter (hereinafter, the delimiter position). In other words, the delimiter may be held as separate data that links the word position in the foreign language text to the position of the delimiter. In either case, it is possible to display the phrase position of the foreign language text in association with the delimiter position.

[0013] 1 is a block diagram showing the configuration of an electronic device (electronic dictionary) 1 according to this embodiment. The electronic device 1 may be configured as a portable device dedicated to an electronic dictionary, as described below, or may be configured as a PDA (personal digital assistant), PC (personal computer), mobile phone, electronic book, portable game machine, or the like, equipped with a dictionary function. The electronic device 1 is capable of inputting (displaying) a delimiter at any position in a foreign language (e.g., English) text in response to a manual operation by a user.

[0014] The electronic device 1 has a CPU 11, a storage unit 12, a key input unit 13, a touch panel display unit 14, and a communication unit 15. The CPU 11 is a CPU that controls various operations of the electronic device 1. The CPU 11 may be a CPU, an ASIC, an FPGA, or the like. The CPU 11 may also be composed of two or more CPUs. The CPU 11 operates as a determination unit that determines input of a specific operation key in the key input unit 13, or input of a touch operation (such as a touch with a finger or a touch with a stylus pen) on the touch panel 14b. The CPU 11 also operates as a control unit that changes the processing to be executed depending on the operation of the specific operation key or the touch operation.

[0015] The storage unit 12 stores a system program (not shown) that controls the overall operation of the electronic device 1, a communication program (not shown) for data communication with a server (cloud) on a network via the communication unit 15, a translation program 12a for translating a foreign language text, a delimiter control program 12b for inputting and displaying delimiters for a foreign language text and displaying a learning level, various dictionary data 12c for translation, foreign language text data (plural) 12d including delimiter position information, input grammar rule data 12e for specifying the input position of a delimiter, and the like. The delimiter position information is information indicating the position where a delimiter should be input for each input grammar rule in a foreign language text. The input grammar rule data 12e is a grammar rule that specifies the position where a delimiter should be input. The key input unit 13 is various keys for a user to operate the electronic device 1. When an operation using the key input unit 13 is accepted, an input signal corresponding to the operation is transmitted to the CPU 11.

[0016] The touch panel display unit 14 has a structure in which a touch position detection device that detects the position touched by the user with a stylus pen or finger and a display device are integrated, and is configured by overlapping the touch panel 14b on the display unit 14a. The display unit 14a is an m x n dot display such as a liquid crystal display, and displays foreign language text, menu buttons, delimiters, translation results, learning levels, and input grammar rules according to the learning levels. The communication unit 15 performs data communication with a server (not shown) via a network under the control of the CPU 11.

[0017] In addition, since the present embodiment is mainly directed to inputting, displaying and setting delimiters for performing slash reading on foreign language text, a description of the translation operation of foreign language text will be omitted.

[0018] B. Operation of the embodiment 2 and 3 are flow charts for explaining the basic operation of the electronic device 1 according to this embodiment. It is assumed that the electronic device 1 has loaded a foreign language text 12d including delimiter position information that has been stored in advance. The CPU 11 first loads the default input grammar rule data 12e used for slash input (step S10), and displays the foreign language text (English text in this case) on the touch panel display unit 14 (display unit 14a) (step S12).

[0019] Here, Fig. 4 is a schematic diagram showing an example of a delimiter input screen of the electronic device 1 of this embodiment. As shown in Fig. 4, a foreign language text (in this case, English) is displayed in the upper part of the display unit 14a, and a slash input start button 21a and a setting button 21b are displayed in the lower part of the display unit 14a.

[0020] Next, the CPU 11 determines whether the setting button 21b has been pressed (touched) (step S14), and if the setting button 21b has been pressed (touched) (YES in step S14), it displays a grammar setting screen on the touch panel display unit 14 (display unit 14a) (step S16).

[0021] 5 is a schematic diagram showing an example of a grammar setting screen 22 for setting input grammar rules for delimiters in the electronic device 1 of this embodiment. As shown in FIG. 5, when the setting button 21b is pressed (touched), the grammar setting screen 22 is displayed on the touch panel display unit 14 (display unit 14a). The grammar setting screen 22 is a screen for setting input grammar rules based on the input grammar rule data 12e when inputting delimiters into the foreign language text 20.

[0022] The grammar setting screen 22 displays a list of input grammar rules that specify the position where a delimiter should be input, including "before a preposition," "before a relative pronoun," "before a present participle or past participle," "before a conjunction," "before or after a comma, colon, etc.," "after a long subject," and "before a long object." Each input grammar rule has a check box for setting whether the input grammar rule is valid or invalid. The user inputs a delimiter into a predetermined position in the foreign language text 20 according to the input grammar rule whose check box is checked. Which input grammar rule is valid or invalid is set according to the input grammar rule data 12e. For example, if the check box "before a preposition" is checked, it means that a delimiter is input before a preposition in the foreign language text 20, and if the check box "before a relative pronoun" is checked, it means that a delimiter is input before a relative pronoun. The same applies to other grammar conditions.

[0023] In the grammar setting screen 22 that is displayed for the first time, valid / invalid is set according to the default grammar rules read in step S10, and the checkboxes for the input grammar rules that are set to valid are checked. However, as described later, as learning by slash input progresses, which input grammar rules are to be valid or invalid are updated according to the user's learning level. For example, the higher the user's learning level, the fewer the input grammar rules that are to be valid (checked). In other words, as the learning level increases, the number of places where delimiters should be input decreases, and the user can read longer sentences. In other words, even if the learning level increases, if the user inputs many delimiters and reads short sentences, the user cannot learn efficiently. Therefore, as the user's learning level increases, the number of delimiters that must be input is reduced, and the user can learn efficiently by reading sentences of a length appropriate to the learning level.

[0024] The user can also enable / disable the input grammar rules on the grammar setting screen 22. In other words, the user can select (change) which input grammar rules to enable or disable when the user wishes to input more delimiters to read in shorter sentences or fewer delimiters to read in longer sentences depending on the user's learning level or the contents of the foreign language text.

[0025] After the user checks which input grammar rules are enabled (checked) on the displayed grammar setting screen 22, or enables / disables the input grammar rules according to the user's own learning level (acquisition level), etc., the user presses (touches) the decision button 21c. When the decision button 21c is pressed (touched), the CPU 11 returns to the display screen of the foreign language text 20 shown in FIG.

[0026] The CPU 11 determines whether or not the slash input start button 21a has been pressed (touched) on the display screen of the foreign language text 20 shown in FIG. 4 (step S18), and if the slash input start button 21a has not been pressed (touched) (NO in step S18), the process returns to step S12 and the display of the foreign language text 20 shown in FIG. 4 continues.

[0027] On the other hand, if the slash input start button 21a is pressed (touched) (YES in step S18), the grammar setting screen 22 shown in FIG. 5 is displayed again for final confirmation (step S20). The user checks the input grammar rules again. The user may also further change the input grammar rules at this stage. Next, the CPU 11 displays the delimiter input screen 23 on the touch panel display unit 14 (display unit 14a) (step S22) and starts a timer (step S24).

[0028] 6 is a schematic diagram showing an example of a delimiter input screen of the electronic device 1 of the present embodiment. On the delimiter input screen 23 shown in FIG. 6, the user touches a predetermined position of the foreign language text (with a finger, a stylus pen, or the like) according to the input grammar rule confirmed (selected) on the grammar setting screen 22 shown in FIG.

[0029] During the delimiter input process, the CPU 11 determines whether or not a delimiter has been input (step S26), and if no delimiter has been input (NO in step S26), determines whether or not the input has been completed, that is, whether or not the slash input end button 21d on the delimiter input screen 23 shown in Fig. 6 has been pressed (touched) (step S32). If the slash input end button 21d on the delimiter input screen 23 has not been pressed (NO in step S32), the process returns to step S26.

[0030] On the other hand, if a delimiter has been input (YES in step S26), CPU 11 saves the input position where the delimiter was input and the time elapsed by the timer at that time (step S28). Next, CPU 11 displays a delimiter (slash) at the location touched by the user in foreign language text 20 on delimiter input screen 23 shown in Fig. 6 (step S30). Next, it is determined whether input has been completed (step S32), and if slash input end button 21d has not been pressed (NO in step S32), the process returns to step S26.

[0031] Then, the CPU 11 repeats the above steps S26 to S32 until the slash input end button 21d is pressed on the delimiter input screen 23 shown in FIG. 6. More specifically, the user touches a predetermined position of the foreign language text (with a finger, a stylus pen, or the like) according to the input grammar rules. When the predetermined position is touched, the CPU 11 displays a delimiter (slash) at the position touched by the user. The user reads the sentence (English sentence) between the previous delimiter and the delimiter input this time. When the reading is finished, the user touches the next predetermined position to display the delimiter (slash), and again reads the sentence (English sentence) between the delimiters. In this way, the user repeats the designation of the input position of the delimiter and the reading of the sentence between the previous delimiter and the current delimiter. Every time the user designates the input position of the delimiter (every time the delimiter is displayed), the CPU 11 saves the input position and the elapsed time at that time. The touch panel display unit 14 (display unit 14a) of the electronic device 1 displays an elapsed time 21e measured by a timer, as shown in FIG.

[0032] Then, when the user has finished inputting all the delimiters and reading the sentences and presses the slash input end button 21d on the delimiter input screen 23 shown in Fig. 6 (YES in step S32), the CPU 11 stops the timer (step S34). Next, the CPU 11 analyzes the input position, elapsed time, input frequency, etc. of the delimiters saved in step S28 (step S36), and displays the analysis result (learning level) on the touch panel display unit 14 (display unit 14a) (step S38).

[0033] Here, Fig. 7 is a schematic diagram showing an example of an analysis result screen of the electronic device 1 of this embodiment. In the analysis result screen 24 shown in Fig. 7, the analysis results consisting of five indices, "degree of agreement with grammar rules," "input frequency," "reading speed," "speed stability," and "level of understanding of key sentences," derived based on the input position of delimiters, elapsed time, or input frequency, are displayed in a radar chart 25 with scores given out of 20 points, and a total score 26 obtained by adding up the scores for all the indices is also displayed.

[0034] For "degree of agreement with grammar rules," points are subtracted if the input position of a delimiter does not match the input grammar rules, or if the delimiter is not input at the position specified by the input grammar rules. For "input frequency," points are added if the number of delimiters actually input is small compared to the number of delimiters that would be input according to the input grammar rules. This means that if a user actually looks at a foreign language text and determines that the text can be read sufficiently without inputting delimiters at the positions specified by the input grammar rules, input of delimiters may be omitted, and the number of delimiters actually input will be smaller than the number of delimiters that would be input according to the input grammar rules.

[0035] In other words, if the number of delimiters actually input is small compared to the number of delimiters according to the input grammar rules, this indicates that the user's learning level is higher than expected, so "input frequency" is increased. In this case, the user may not fully understand grammar and may not input delimiters at the positions specified by the input grammar rules, but this corresponds to a case where delimiters are not input at the positions specified by the input grammar rules, so "grammar rule agreement" is decreased.

[0036] If the score for "input frequency" is high but the score for "grammar rule agreement" is low, the user can see that the settings of the input grammar rules in the grammar rules for slash input do not match the current learning level. Therefore, the next time slash reading is performed, the settings of the input grammar rules in the grammar rules for slash input can be changed appropriately. Alternatively, in the electronic device 1, if the score for "input frequency" is high but the score for "grammar rule agreement" is low, it may be determined that the settings of the input grammar rules in the grammar rules for slash input do not match the current learning level, and the settings of the input grammar rules in the grammar rules for slash input may be automatically changed.

[0037] "Reading speed" is judged from the time elapsed until the end of reading in relation to the number of words in a long text, and a score is given according to the judgment result. "Speed ​​stability" is judged based on the difference in input speed between the first and second halves of inputting delimiters, and a score is given based on information on whether there are sentences where the input speed was extremely slow. "Key sentence comprehension" judges the comprehension level of a specific sentence (key sentence) that is considered important for comprehension of the content of a long text from the degree of agreement with grammar rules and the input speed, and a score is given according to the comprehension level. The user can check the analysis results on the analysis result screen 24 shown in FIG. 7 and know his / her current learning level from the score and balance of each indicator and the total score 26 displayed in a radar chart 25.

[0038] Next, the CPU 11 updates the input grammar rules for inputting delimiters into the foreign language text 20 based on the analysis results indicating the user's reading comprehension in order to adjust the learning level for the next and subsequent implementations (step S40).

[0039] Here, FIG. 8 is a schematic diagram showing an example of a grammar setting screen 22 for specifying the input position of a delimiter, which is updated according to the learning level in the electronic device 1 according to this embodiment. For example, as shown in FIG. 8(a), the default grammar rules enable all input grammar rules. By enabling all of them, it is aimed at so-called beginners (beginners in slash reading). If the user becomes accustomed to slash reading by performing slash reading several times and the total score 26 indicating reading comprehension increases, as shown in FIG. 8(b), "after a long subject" and "before a long object" are disabled. This allows the number of delimiter inputs to be reduced, and slash reading can be performed according to the learning level. Furthermore, if the total score 26 increases, as shown in FIG. 8(c), in addition to "after a long subject" and "before a long object", "before a conjunction" and "before or after a comma, colon, etc." are disabled. This allows the number of delimiter inputs to be further reduced, and slash reading can be performed in longer sentence units according to the learning level. As described above, the grammar rules for entering delimiters are updated according to the learning level, but the user can change them as appropriate from the grammar setting screen 22 shown in FIG. 6 before starting slash reading.

[0040] C. Variation 1 In the above-mentioned embodiment, when judging the user's reading comprehension, some questions about the contents of the foreign language text may be presented to the user, and the answers from the user to the questions may be collected and the correctness or incorrectness of the answers may be used as an index for judging the reading comprehension. In other words, if the correct answer rate is high, the total score 26 of the reading comprehension may be added. In this case, sentences or paragraphs for which the user's understanding is low may be estimated based on the input positions of delimiters and the time required for input, and questions related to those sentences or paragraphs may be given priority.

[0041] D. Variation 2 FIG. 9 is a schematic diagram showing an example of Modification 2 of the electronic device 1 of the present embodiment. In Modification 2 of the present embodiment, as shown in FIG. 9, a warning screen 27 may be displayed when the delimiter position is grammatically inappropriate, to promote the user's understanding. The illustrated example shows a state in which the user is about to input a delimiter between "even" and "though". In this case, "even though" is an idiom (phrase or idiomatic phrase) in which two or more words are combined to have a special meaning, such as "despite being", and "despite being", so it is not preferable to separate "even" and "though" with the delimiter and interpret it (it cannot be interpreted correctly). Therefore, a warning is issued that inputting a delimiter between "even" and "though" is inappropriate.

[0042] E. Variation 3 Fig. 10 is a schematic diagram for explaining Modification 3 of the electronic device 1 of this embodiment. In Modification 3 of this embodiment, as shown in Fig. 10, the user may be prompted to input a delimiter other than a slash (for example, an underline) for the subject of an English sentence, and the correctness of the result may be judged and displayed in a pop-up window 28 to facilitate the user's understanding. In the illustrated example, the user is prompted to input an underline for the subject. In response, the user has underlined the subject "I", and so the display indicates that the answer is correct, saying "It's the subject. That's correct."

[0043] In the above-described embodiment, all processing is performed by the electronic device 1 alone, but this is not limited to the above. Foreign language text, break position information, input grammar rules, etc. may be downloaded from a server (cloud) on the Internet, and the learning level may be estimated on the server (cloud) side and provided to the electronic device 1.

[0044] In addition, in the above-described embodiment, the input grammar rules for inputting delimiters are changed according to the user's learning level. In addition to this, the content of the foreign language text to be presented to the user (number (quantity) of vocabulary, short / long sentences, etc.) may be determined based on the user's learning level, and foreign language text appropriate to the user's learning level may be selectively presented.

[0045] According to this embodiment, when a point before or after a word in a sentence is selected based on a user operation, a delimiter is displayed at the selected point, and the user's learning level is estimated based on information about the displayed delimiter, so that the user's learning level when reading a sentence can be effectively estimated.

[0046] According to the present embodiment described above, the information relating to the delimiters includes position information of the delimiters displayed in the text, so that the learning level of the user when reading the text can be effectively estimated.

[0047] According to the present embodiment described above, the learning level is indicated by a score that represents the degree to which the user was able to input delimiters appropriately, so that the user's learning level when reading a sentence can be effectively estimated and the user's learning level can be effectively presented to the user.

[0048] According to the present embodiment described above, the input grammar rules that specify the locations where delimiters should be displayed can be set by the user, so that the learning level of the user when reading a sentence can be effectively estimated.

[0049] According to the present embodiment described above, the input grammar rules that specify the locations where delimiters should be displayed are changed based on the estimated learning level of the user, so that the learning level of the user when comprehending a sentence can be effectively estimated.

[0050] According to the present embodiment described above, at least one question is presented regarding the content of the text, and the learning level of the user is estimated based on the user's answer to the at least one question, so that the learning level of the user when reading the text can be effectively estimated.

[0051] According to the above-described embodiment, the user's learning level is estimated based on at least one of the following information regarding delimiters: grammar rule agreement, which is the agreement with the input grammar rules that specify the locations where delimiters should be displayed; input frequency, which indicates the number of delimiters; reading speed, which indicates the elapsed time until reading is completed relative to the number of words in a sentence; speed stability, which indicates fluctuations in the speed at which the locations where delimiters should be displayed are selected; and key sentence comprehension, which is derived from the grammar rule agreement and the input speed of delimiters for specific sentences that are considered important for comprehension of the content of a long sentence, so that the user's learning level when reading a sentence can be effectively estimated.

[0052] According to the present embodiment described above, information regarding the estimated learning level of the user is displayed on the display unit, so that the learning level of the user when comprehending a text can be effectively estimated and the learning level of the user can be effectively presented to the user.

[0053] According to the present embodiment described above, it is determined whether the portion selected by the user's operation is grammatically appropriate for displaying a delimiter, so that the learning level of the user when reading a sentence can be effectively estimated.

[0054] According to the present embodiment described above, the user is prompted to input specific delimiter marks for specific words in a sentence, and the correctness of the input is determined based on the position of the specific delimiter mark input by the user's operation, so that the user's learning level when reading a sentence can be effectively estimated.
