  The CPU 2 controls the operation of each unit in accordance with a program (a control program 31 described later) stored in the storage device 3.

  The storage device 3 is configured by, for example, a flash ROM (Read Only Memory), and stores programs and data for realizing various functions. Specifically, the storage device 3 stores a control program 31, a dictionary database (dictionary DB) 32, a learning word database (learning word DB) 33, and an affix database (affix DB) 34. .

  The control program 31 is a program for causing the CPU 2 to execute word display processing (see FIG. 4) described later.

  The dictionary DB 32 is a database used when the language learning device 1 functions as an electronic dictionary, and includes “words”, detailed “description information” including the meaning of the words, “example sentences” using the words, and the like. Are stored in association with each other.

  The learning word DB 33 and the affix DB 34 use the language learning device 1 to decompose words into affixes (prefixes, suffixes) and stem word components and learn words that share common word components. It is a database used for.

  The data structure of the learning word data stored in the learning word DB 33 will be described with reference to FIG. FIG. 2 is an example of learning word data in the learning word DB 33.

  As shown in FIG. 2, a plurality of learning word data are stored in the learning word DB 33 in association with a learning word 331 and meaning information 332. Further, the learning word data stored in the learning word DB 33 is sorted so that the character strings of the learning words 331 are in ascending order within a range where the prefixes are common.

  Here, the learning word 331 is a learning method using the language learning device 1 according to the present embodiment, that is, words are divided into affix and stem word constituent elements, and words having common word constituent elements are collected together. This is a word to be learned in the learning method for learning. The learning word 331 is stored in the learning word DB 33 as a character string with delimiter data (“/”, “//”) indicating the delimitation between the affix and the stem. In FIG. 2, delimiter data indicating the delimiter between the prefix and the stem is indicated by “/”, and delimiter data indicating the delimiter between the suffix and the stem is indicated by “//”. It is not limited to this.

  The meaning information 332 is stored in the learning word DB 33 with the simple meaning of the learning word 331 associated with the learning word 331.

  Next, the data structure of the affix data stored in the affix DB 34 will be described with reference to FIG. FIG. 3 is an example of affix data in the affix DB 34, (a) is an example of prefix data in the prefix database 34a, and (b) is an example of suffix data in the suffix database 34b.

  The suffix DB 34 has a prefix database (prefix DB) 34a in which prefix data is stored, and a suffix database (suffix DB) 34b in which suffix data is stored. As shown in FIG. 3A, a plurality of prefixes 341a are stored as character strings in the prefix DB 34a. As shown in FIG. 3B, a plurality of suffixes 341b are stored as character strings in the suffix DB 34b.

  Returning to FIG. 1, the RAM 4 includes a working memory area that temporarily holds a program (control program 31) executed by the CPU 2, data related to execution of these programs, and the like. Here, the RAM 4 has display data 41.

  The CPU 2 outputs the display data 41 held in the RAM 4 to the display unit 5d as a display signal. Thereby, the display data 41 is displayed on the display unit 5d.

  The touch panel 5t is, for example, a capacitive touch panel that supports multi-touch, and is disposed on the front surface of the display unit 5d. The touch panel 5t receives a touch operation by the user, and detects a touched position (a position where the touch-panel-equipped display unit 5 is touched) and the number, and a flick (touches the touch-panel-equipped display unit 5 and slides). It can be done. The touch panel 5t outputs the detected signal to the CPU 2. In the following description, the user is described as operating the touch panel 5t with a finger, but a stylus or the like may be used.

  The input unit 6 includes a key that accepts an operation from the user, and outputs a signal corresponding to the operated key to the CPU 2.

≪Word display processing≫
Next, operation | movement of the language learning apparatus 1 which concerns on this embodiment is demonstrated using FIGS. 4-6. FIG. 4 is a flowchart showing word display processing of the language learning device 1 according to the present embodiment.

In step S1, the CPU 2 specifies one learning word 331 from the learning word DB 33 and displays it on the display unit 5d.
First, the CPU 2 identifies one learning word 331 from the learning word DB 33. For this specification, one word may be specified at random, the learning word 331 displayed at the end of the previous time may be specified, and the specifying method is not limited. Then, the CPU 2 creates display data 41 that displays the specified learning word 331 and the meaning information 332 corresponding to the specified learning word 331. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal.

  In step S2, CPU2 determines whether the display part 5 with a touch panel was touched by the user. When touched (S2 / Yes), the process of the CPU 2 proceeds to step S3. If it is not touched (S2 · No), it waits in step S2 until it is touched.

  In step S3, the CPU 2 determines whether or not the position of the learning word displayed on the display unit 5d has been touched based on the signal (position information) from the touch panel 5t and the display data 41. When the position of the learning word is touched (S3 / Yes), the process of the CPU 2 proceeds to step S3. When the position of the learning word is not touched (S3 / No), the processing of the CPU 2 shifts to other processing.

  In step S4, the CPU 2 determines whether the number touched is one point based on a signal from the touch panel 5t. When the number touched is one point (S4, Yes), the process of the CPU 2 proceeds to step S5. When the number touched is not one point (S4, No), the process of the CPU 2 proceeds to step S10.

  In step S5, the CPU 2 determines whether or not a flick operation has been performed following the touch in step S2, based on a signal from the touch panel 5t. When the flick operation is performed (S5 / Yes), the process of the CPU 2 proceeds to step S6. If the flick operation has not been performed (No at S5), the process waits at step S5 until the flick operation is performed. In addition, although illustration is abbreviate | omitted, when a user lifts a finger | toe without performing a flick operation, you may make it return to step S2.

In step S <b> 6, the CPU 2 acquires the next learning word 331 corresponding to the direction of the flick operation from the learning word DB 33.
That is, when the flick operation is performed in the upward direction, the CPU 2 acquires the learning word 331 that is one above the learning word 331 specified in step S1 from the learning word DB 33. For example, in the example of FIG. 2, when the specified learning word 331 is “con / flict”, “con / film” that is one level higher is acquired. When the flick operation is performed in the downward direction, the CPU 2 acquires the learning word 331 that is one level lower than the learning word 331 specified in step S <b> 1 from the learning word DB 33. For example, in the example of FIG. 2, when the identified learning word 331 is “con / flict”, “con / front”, which is one level lower, is acquired.

  In step S7, the CPU 2 determines whether or not the next learning word 331 has been acquired in step S6 (is there a word?). When the next learning word 331 can be acquired (S7 / Yes), the processing of the CPU 2 proceeds to step S8. When the next learning word 331 cannot be acquired (S7, No), the process of the CPU 2 proceeds to step S9.

In step S8, the CPU 2 displays the learning word 331 acquired in step S6 on the display unit 5d.
That is, the CPU 2 creates display data 41 that displays the learned word 331 acquired in step S6 and the meaning information 332 corresponding to the acquired learned word 331. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. Thus, the CPU 2 ends the word display process.

In step S9, the CPU 2 displays “no corresponding word” on the display unit 5d.
That is, the CPU 2 creates display data 41 indicating “no corresponding word”. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. Thus, the CPU 2 ends the word display process.

In step S10, that is, when the word is touched and the touch is a plurality of points, the CPU 2 divides the learning word into affixing (prefix, suffix) and stem word constituent elements and displays them on the display unit 5d. indicate.
That is, the CPU 2 creates display data 41 for displaying the learned word 331 specified in step S1 and the meaning information 332 corresponding to the specified learned word 331. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Further, the CPU 2 creates display data 41 that displays the affix (prefix, suffix) and the stem in an identifiable manner based on the delimiter data attached to the learned word 331 stored in the learned word DB 33. . For example, the affix (prefix, suffix) and the stem may have different character colors, different character background colors (markers), or a frame surrounding the affix and a stem may be displayed. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal.

  In step S11, based on the signal from the touch panel 5t, the CPU 2 determines whether or not the user touches the affix position of the learning word or the stem position of the learning word displayed on the display unit 5d. When the position of the affix of the learning word or the position of the stem of the learning word is touched (S11 / Yes), the processing of the CPU 2 proceeds to step S12. When the position of the affix of the learning word or the position of the stem of the learning word is not touched (S11 / No), the process of the CPU 2 stands by in step S11 until it is touched.

In step S12, the CPU 2 identifies and displays the touched portion and displays it on the display unit 5d.
That is, when the affix position of the learning word displayed on the display unit 5d is touched, the affix character color is further changed, the background color (marker) of the affix character is further changed, or the frame surrounding the affix Or the touched part can be identified. The same applies to the case where the position of the stem of the learning word displayed on the display unit 5d is touched.

  In step S13, the CPU 2 determines whether or not a flick operation has been performed following the retouch in step S11, based on a signal from the touch panel 5t. When the flick operation is performed (S13 / Yes), the process of the CPU 2 proceeds to step S14. If the flick operation has not been performed (No at S13), the process waits at step S13 until the flick operation is performed. In addition, although illustration is abbreviate | omitted, when a user lifts a finger | toe without performing a flick operation, you may make it return to step S10.

  In step S14, it is determined whether the position touched in step S11 and flicked in step S13 is the position of the learned word affix or the position of the learned word stem. In the case of the affix position of the learning word (S14, affix), the process of the CPU 2 proceeds to step S15. In the case of the stem position of the learning word (S14 / stem stem), the processing of the CPU 2 proceeds to step S16.

  In step S15, the CPU 2 executes an affix change process. Details will be described later with reference to FIG. Thus, the CPU 2 ends the word display process.

  In step S16, the CPU 2 executes a stem change process. Details will be described later with reference to FIG. Thus, the CPU 2 ends the word display process.

  Next, the affix changing process in step S15 will be described with reference to FIG. FIG. 5 is a flowchart showing the affix change processing of the language learning device 1 according to the present embodiment.

  In step S21, the CPU 2 acquires the next affix (prefix 341a, suffix 341b) corresponding to the direction of the flick operation from the affix DB 34 (prefix DB 34a, suffix DB 34b).

  That is, the position touched in step S11 is the position of the prefix of the learning word, and when the flick operation is performed in the upward direction in step S13, the CPU 2 learns the learning word 331 specified in step S1 from the prefix DB 34a of the affix DB 34. A prefix 341a that is one level higher than the prefix of is acquired. For example, in the example of FIG. 3A, when the prefix of the identified learning word 331 is “con”, “com” that is one level higher is acquired. If the position touched in step S11 is the position of the prefix of the learning word and if a downward flick operation is performed in step S13, the CPU 2 prefixes the learning word 331 specified in step S1 from the prefix DB 34a of the affix DB 34. The prefix 341a one level below is acquired. For example, in the example of FIG. 3A, when the prefix of the specified learning word 331 is “con”, “dis” that is one level lower is acquired. When the position touched in step S11 is the position of the suffix of the learning word and the flick operation is performed in the upward direction in step S13, the CPU 2 determines the suffix of the learning word 331 specified in step S1 from the suffix DB 34b of the suffix DB 34. Acquires the suffix 341b which is one above the word. For example, in the example of FIG. 3B, when the suffix of the specified learning word 331 is “ate”, “able” that is one higher is acquired. When the position touched in step S11 is the position of the suffix of the learning word and the flick operation is performed downward in step S13, the CPU 2 adds the suffix of the learning word 331 specified in step S1 from the prefix DB 34a of the suffix DB 34. Acquires the suffix 341b immediately below the lexicon. For example, in the example of FIG. 3B, when the suffix of the specified learning word 331 is “ful”, the next “fy” is acquired.

  In step S22, the CPU 2 determines whether or not the next affix (prefix 341a, suffix 341b) has been acquired in step S21 (has an affix?). When the next affix (prefix 341a, suffix 341b) can be acquired (S22 / Yes), the process of the CPU 2 proceeds to step S23. If the next affix (prefix 341a, suffix 341b) cannot be acquired (No at S22), the process of the CPU 2 proceeds to step S26.

  In step S23, the CPU 2 generates a character string obtained by replacing the affix of the specified learning word 331 with the affix (prefix 341a and suffix 341b) acquired in step S21 from the character string of the learning word 331 specified in step S1. To do. Note that the character string generated in step S23 also includes delimiter data.

  In step S24, the CPU 2 determines whether or not the character string generated in step S23 exists in the learning word 331 of the learning word DB 33. If it exists (S24, Yes), the process of the CPU 2 proceeds to step S25. If it does not exist (No at S24), the process of the CPU 2 returns to Step S21.

  In step S21 after the first time, the next affix (prefix 341a, suffix 341b) corresponding to the direction of the flick operation is acquired based on the affix of the learning word 331 specified in step S1. On the other hand, in the second and subsequent steps S21 that return from step S24, the next affix (prefix 341a, suffix 341b) corresponding to the direction of the flick operation is acquired based on the affix of the character string generated in step S23. To do.

In step S25, the CPU 2 displays the learning word 331 whose existence has been confirmed in step S24 on the display unit 5d.
That is, the CPU 2 creates display data 41 that displays the learned word 331 that has been confirmed in step S24 and the meaning information 332 corresponding to the learned word 331 that has been confirmed to exist. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. As described above, the CPU 2 ends the affix change process shown in FIG. 5 (ie, step S15 in FIG. 4).

On the other hand, in step S26, the CPU 2 displays “no corresponding word” on the display unit 5d.
That is, the CPU 2 creates display data 41 indicating “no corresponding word”. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. As described above, the CPU 2 ends the affix change process shown in FIG. 5 (ie, step S15 in FIG. 4).

  Next, the stem change process in step S16 will be described with reference to FIG. FIG. 6 is a flowchart showing the stem change processing of the language learning device 1 according to the present embodiment.

  In step S31, the CPU 2 determines whether or not the learning word 331 specified in step S1 has a prefix. If there is a prefix (S31, Yes), the processing of the CPU 2 proceeds to step S32. If there is no prefix (S31, No), the process of the CPU 2 proceeds to step S37.

In step S <b> 32, the CPU 2 acquires the next learned word 331 corresponding to the direction of the flick operation from the learned word DB 33.
That is, when a flick operation is performed in the upward direction in step S13, the CPU 2 acquires the learning word 331 that is one above the learning word 331 specified in step S1 from the learning word DB 33. When a downward flick operation is performed in step S13, the CPU 2 acquires a learning word 331 that is one lower than the learning word 331 specified in step S1 from the learning word DB 33.

  In step S33, the CPU 2 determines whether or not the next learning word 331 has been acquired in step S32 (there is a word?). When the next learning word 331 can be acquired (S33 / Yes), the processing of the CPU 2 proceeds to step S34. When the next learning word 331 cannot be acquired (No at S33), the process of the CPU 2 proceeds to step S36.

  In step S34, the CPU 2 determines whether or not the prefix of the learning word 331 specified in step S1 is the same as the prefix of the learning word 331 acquired in step S32. If the prefixes are the same (S34 / Yes), the process of the CPU 2 proceeds to step S35. If the prefixes are not the same (No at S34), the process of the CPU 2 proceeds to step S36.

In step S35, the CPU 2 displays the learning word 331 acquired in step S32 on the display unit 5d.
That is, the CPU 2 creates display data 41 that displays the learned word 331 acquired in step S32 and the meaning information 332 corresponding to the acquired learned word 331. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. As described above, the CPU 2 ends the stem change process shown in FIG. 6 (that is, step S16 in FIG. 4).

In step S36, the CPU 2 displays “no corresponding word” on the display unit 5d.
That is, the CPU 2 creates display data 41 indicating “no corresponding word”. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal. As described above, the CPU 2 ends the stem change process shown in FIG. 6 (that is, step S16 in FIG. 4).

  On the other hand, if it is determined in step S31 that there is no prefix, in step S37, the CPU 2 determines whether the learning word 331 specified in step S1 has a suffix. If there is a suffix (S37, Yes), the process of the CPU 2 proceeds to step S38. If there is no suffix (S37, No), the CPU 2 determines NOP (does nothing). Incidentally, the learning word 331 stored in the learning word DB 33, as described above, decomposes the word into affix (prefix, suffix) and stem word constituent elements, and collects words having common word constituent elements. Therefore, the situation of (S37 No) does not occur basically because it is a word to be learned in the learning method to be learned and is a word having a suffix (prefix, suffix) and a stem.

In step S <b> 38, the CPU 2 acquires the next learning word 331 corresponding to the direction of the flick operation from the learning word DB 33.
That is, when the upward flick operation is performed in step S13 described above, the CPU 2 acquires the learning word 331 that is one above the learning word 331 specified in step S1 from the learning word DB 33. Similarly, when the flick operation is performed in the downward direction in step S13, the CPU 2 acquires the learning word 331 immediately below the learning word 331 specified in step S1 from the learning word DB 33.

  In step S39, the CPU 2 determines whether or not the next learning word 331 has been acquired in step S38 (is there a word?). When the next learning word 331 can be acquired (S39 / Yes), the processing of the CPU 2 proceeds to step S40. When the next learning word 331 cannot be acquired (S39, No), the processing of the CPU 2 proceeds to step S42.

  In step S40, the CPU 2 determines whether or not the suffix of the learning word 331 specified in step S1 is the same as the suffix of the learning word 331 acquired in step S38. If the suffixes are the same (S40 / Yes), the process of the CPU 2 proceeds to step S41. When the suffixes are not the same (S40, No), the process of the CPU 2 returns to step S38.

  In the first and subsequent steps S38, the next learning word 331 corresponding to the direction of the flick operation is acquired based on the learning word 331 specified in step S1. On the other hand, in the second and subsequent steps S38 returned from step S40, the next learning word 331 corresponding to the direction of the flick operation is acquired based on the learning word 331 acquired in the previous step S38.

In step S41, the CPU 2 displays the learning word 331 acquired in step S38 on the display unit 5d.
That is, the CPU 2 creates display data 41 that displays the learned word 331 acquired in step S38 and the meaning information 332 corresponding to the acquired learned word 331.

<Effect>
As described above, according to the language learning device 1 according to the present embodiment, as shown in FIG. 8B and FIG. 9B, each word is composed of a suffix (prefix, suffix) and a stem. It is displayed divided into elements, and other words with the same affix or stem are displayed by intuitive operation (see FIG. 8 (c), FIG. 8 (e), FIG. 9 (c), FIG. 9 (e)). (Refer to FIG. 8D, FIG. 8F, FIG. 9D, and FIG. 9F). As a result, words having common affixes or stems can be efficiently learned together, and the user's willingness to learn can be improved.

  Moreover, according to the language learning apparatus 1 which concerns on this embodiment, the calculation cost required for the search process which searches the next word which has a common word component can be suppressed.

  For example, when the language learning apparatus 1 according to the present embodiment displays other words with common stems by flicking the prefix, as shown in the loop from step S21 to step S24 in FIG. With reference to the affix DB 34, a character string in which the prefix is replaced is generated, and it is determined whether or not the replaced character string exists in the learning word DB 33. Therefore, in the language learning device 1 according to the present embodiment, the search process is completed by searching for the prefix registration total number −1 registered in the prefix DB 34a of the affix DB 34 at the maximum. The same applies to the case where another word having a common stem is displayed by flicking the suffix.

  Incidentally, when the affix DB 34 is not provided, the learning word DB 33 is referred to search for another word having a common stem. In this case, the maximum number of learning word registrations −1 registered in the learning word DB 33 is set as a search target, and words whose stem character strings match these words are Boyer-Moore character string search algorithms. (BM method) or the like is used to search for a character string, and the calculation cost increases.

  Further, the language learning device 1 according to the present embodiment, when learning other words having a common prefix by flicking the stem in the learning word composed of the prefix and the stem, is changed from step S32 to step S34 in FIG. As shown, the search process is completed with a single search.

  Further, the language learning device 1 according to the present embodiment, in the learning word composed of the stem and the suffix, flicks the stem and displays another word having a common suffix, from step S38 to step S40 in FIG. As shown, the search process is completed with the learning word registration total −1 registered in the learning word DB 33 at the maximum.

  As described above, according to the language learning device 1 according to the present embodiment related to the present embodiment, the language learning device 1 includes the arithmetic processing device (CPU 2) having a low arithmetic processing capability while suppressing the calculation cost required for the search processing. However, other words with common affixes or stems can be displayed with good response, and the user's willingness to learn can be enhanced.

  The language learning device 1 is configured as a portable information display device such as an electronic dictionary device, and is generally driven by a built-in battery. Here, as the calculation cost required for the search process increases, the battery consumption increases, the driving time is shortened, and the charging frequency is increased. The language learning device 1 according to the present embodiment suppresses battery consumption and suppresses charging frequency by suppressing the calculation cost required for the search process. Thereby, decline of the user's willingness to learn by the battery of the language learning apparatus 1 etc. can be prevented.

  In step S52, the CPU 2 determines whether or not the example sentence display is set. When the example sentence display is set (S52 / Yes), the CPU 2 proceeds to step S53. If the example sentence display is not set (S52, No), the process of the CPU 2 proceeds to step S56.

  In step S <b> 53, the CPU 2 refers to the dictionary DB 32 and acquires “example sentences” using the learning words displayed in the process of step S <b> 51.

  In step S54, the CPU 2 determines whether or not “example sentence” has been acquired in step S53 (there is an example sentence?). If the “example sentence” has been acquired (S54, Yes), the processing of the CPU 2 proceeds to step S55. If the “example sentence” cannot be acquired (S54, No), the process of the CPU 2 proceeds to step S56.

In step S55, the CPU 2 additionally displays “example sentence” on the display unit 5d.
That is, the CPU 2 creates display data 41 that displays the learned word 331 acquired in step S51, the meaning information 332 corresponding to the acquired learned word 331, and the “example sentence” acquired in step S53. The learning word 331 stored in the learning word DB 33 includes delimiter data. Display data 41 for displaying a character string excluding the delimiter data as a learning word is created. Then, the CPU 2 outputs the created display data 41 to the display unit 5d as a display signal.

  In step S56, the CPU 2 determines whether the dictionary reference switch has been operated. Incidentally, the dictionary operation switch may be assigned as a key of the input unit 6 or may be a switch provided in the display unit 5 with a touch panel. When the dictionary reference switch is operated (S56 / Yes), the process of the CPU 2 proceeds to step S57. When the dictionary reference switch is not operated (S56, No), the CPU 2 ends the word display process according to the modification.

  In step S57, the CPU 2 refers to the dictionary DB 32, acquires detailed “explanation information” including the meaning of the learned word displayed in the process of step S51, and displays the learned word and “explanation information” on the display unit 5d. Display additional. Then, the CPU 2 ends the word display process according to the modification.
