  The information processing apparatus 101 is controlled by a CPU (Central Processing Unit) 102. When the information processing apparatus 101 is turned on, the CPU 102 executes an IPL (Initial Program Loader) stored in the ROM 103.

  The IPL reads out an OS (Operating System) program stored in a recording medium such as a hard disk 104, an FD attached to the FD drive 110, or a CD-ROM attached to a CD-ROM drive (CDD) 111. Program to be executed.

  After starting the OS, the CPU 102 executes an application program stored in the hard disk or the like in accordance with a user instruction input from the keyboard 105 or the mouse 106 or in accordance with the contents of a setting file described in advance on the hard disk or the like. Execute.

  In general, stroke information is input by operating the keyboard 105, the mouse 106, or the like. However, a dedicated vertical, horizontal, diagonal, or other line type is input to the information processing apparatus 101. It is also possible to connect an input device to be used and input an instruction using the input device.

  By executing the application program, the information processing apparatus 101 functions as a character input apparatus.

  Various types of information are recorded on storage media such as the hard disk 104, the FD mounted on the FD drive 110, and the CD-ROM mounted on the CD-ROM drive 111.

  The CPU 102 uses the RAM 107 as a temporary work storage area when executing the program. In addition, a register or a cache (not shown) provided in the CPU 102 is used as a temporary working storage area.

(Character input device)
FIG. 2 is an explanatory diagram showing a schematic configuration of the character input device according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  A character input device 201 according to the present embodiment includes a storage unit 202, a stroke input reception unit 203, a conversion unit 204, a candidate presentation unit 205, a selection input reception unit 206, and an output unit 208.

  First, the storage unit 202 stores, for each of a plurality of characters, the character and stroke information representing the number of vertical lines, horizontal lines, diagonal lines, and other lines that form the character shape in association with each other. Is done.

  In the present embodiment, the following notation is used to represent the type and number of lines.

First, use the letter v as the vertical line, use the letter h as the horizontal line, use the letter d as the diagonal line, use the letter c as the other line, and count the number of the letter A number representing the number is appended. The following shows an example of the correspondence between characters and the number of lines.
T ... v3h3
Middle… v3h2
East… h4v3d2
Heart ... d3c1 (the longest line is c)
Child ... v3h3d1c1 (The lower right line is c)
Corps ... v2h2d2c3 (v1h1d1c1 on the left and h1d7c2 on the right. The longest line is c)
Because ... d8h3c1 (The lower right line is c)
辻 ... d2v2h2c1 (the longest line included in the line is c)

  This notation method is also used for stroke input, which will be described later, but other methods can be adopted for the notation method. For example, “|” and “-” represent vertical lines and horizontal lines, and “/” and “\” represent diagonal lines.

  In order to represent the number, there can be a method of notation by adding a number after an alphabetic character, or by repeating the character.

  For example, when there are three vertical lines, it is possible to adopt notations such as “v3” “vvv” “vv2” “v2v” “|||” “| 3” “| 2 |” “|| 2”, etc. it can.

  However, these pieces of information are all commutative and can be converted into some normal form. Therefore, when the number of vertical lines is m, the number of horizontal lines is n, the number of diagonal lines is p, and the number of other lines is q, the notation “vmhndpcq” is adopted as “normal form”, and the normal form is used as stroke information. It will be handled.

  FIG. 3 is an explanatory diagram illustrating a state in which characters and stroke information associated with the characters are stored in the storage unit 202. Hereinafter, a description will be given with reference to FIG.

  The storage unit 202 has a table 301 format, each row 302 has a correspondence relationship, the character column 303 has a character, and the stroke column 304 has character information associated with the character in the row 302 as an attribute. The column 305 stores the attributes of the stroke information.

  There are two types of stroke information attributes: “basic” and “ambiguous”. “Basic” is “correct” stroke information associated with each character. “Ambiguous” is stroke information “highly likely to be mistaken and designated” as stroke information of each character.

  For example, the longest line of the character “heart” is often recognized as “vhd” instead of “c” by beginners of kanji learning. Therefore, the stroke information of “heart” is “d3c1” in the basic stroke information, but “v1h1d4” in the vague stroke information.

  Such basic stroke information (stroke information that accurately counts the type and number of lines) and ambiguous stroke information (stroke information that is likely to be specified incorrectly by beginners) must be prepared for each character in advance. There are many common parts of kanji strokes.

  Accordingly, stroke information that is highly likely to be mistakenly specified is prepared for each of the kanji strokes, and characters, stroke information associated therewith, and their attributes are stored in the storage unit 202 while referring to them appropriately. And so on, various fuzzy searches can be handled.

  In this figure, the configuration of the storage unit 202 is shown in the form of a table 301. However, this information is not a simple table, but adopts a hash structure, a trie structure, and various database structures for performing a search at high speed. May be adopted.

  Accordingly, the RAM 107, the hard disk 104, and the like function as the storage unit 202.

  FIG. 4 is a flowchart showing the flow of control of character input processing for inputting characters with reference to such a storage unit 202. Hereinafter, a description will be given with reference to FIG.

  When the character input process is started, first, the stroke input receiving unit 203 receives a stroke input designating information indicating the number of vertical lines, horizontal lines, diagonal lines, and other lines forming the character shape of the character from the user. (Step S301).

  FIG. 5 is an explanatory diagram showing a screen display state on the display device when accepting a stroke input when the character input device is realized on the computer. Hereinafter, a description will be given with reference to FIG.

  On the screen displayed on the display device 108, the focus is moved to the text box 401 using the mouse 106, and each of the vertical line, horizontal line, diagonal line, and other lines is displayed using the keyboard 105 using the above notation. Enter the number of.

  In the present embodiment, the character input device 201 is realized as a CGI script that can be used from a web browser.

  FIG. 6 is an explanatory diagram showing a state in the middle of inputting a character string for stroke input into the text box 401. In the example of this figure, “h4v3d2” is input.

  When the input is completed, when the button 402 is clicked using the mouse 106, the stroke input is accepted.

  In this way, the keyboard 105 and the mouse 106 function as the stroke input receiving unit 203 in cooperation with the display device 108 and the like. The stroke input as an input result is stored in the RAM 103 or the like.

  Next, the conversion unit 204 converts the information designated for the accepted stroke input into stroke information associated with the input (step S302).

  As described above, the format of the character string in stroke input is uniquely converted to the stroke information which is its normal form, and the conversion can be performed by scanning the character string, classifying each character type, and reading the value for the number. It is.

  Accordingly, the CPU 102 functions as the conversion unit 204 in cooperation with the RAM 103 and the like.

  Next, the candidate display unit 205 acquires characters stored in the storage unit 202 in association with the converted stroke information (step S303).

  As described above, a candidate character is obtained by searching the storage unit 202 using the stroke information of the conversion result as a key.

  Further, the candidate presentation unit 205 presents the character associated with the converted stroke information as a candidate in a different appearance depending on whether or not the converted stroke information is basic stroke information (step S304).

  FIG. 7 is an explanatory diagram showing a state of a display screen that displays character candidates. Hereinafter, a description will be given with reference to FIG.

  As shown in the figure, the candidate presentation unit 205 displays a large character such as “East” or “Hold” in the Exact Match field 451 as a character having “h4v3d2” as basic stroke information.

  Further, the candidate presentation unit 205 displays small characters such as “West” and “Color” as characters having “h4v3d2” as ambiguous stroke information in the Ambiguous Match field 452.

  In this embodiment, the display format of the characters is changed by changing the display location of the candidates to different locations on the screen. In addition, the font, color, size, and thickness of the display are also changed. It is also possible to adopt various appearance change methods, such as changing the type.

  Therefore, the CPU 102 functions as the candidate display unit 205 in cooperation with the RAM 103, the hard disk 104, and the display device 108.

  Further, the selection input receiving unit 206 receives a selection input for designating any one of the characters presented as candidates (step S305).

  As shown in FIG. 7, by directly clicking a character displayed as a candidate using the mouse 105, a selection input for selecting the character is input to the character input device 201.

  Accordingly, the keyboard 105 and the mouse 106 function as the selection input receiving unit 206 in cooperation with the display device 108 and the like. A selection input as an input result is stored in the RAM 103 or the like.

  Finally, the output unit 208 outputs the character designated as the accepted selection input (step S306), and ends this process.

  In the present embodiment, the clicked character is output to another process in the CGI script, and by executing the subsequent process, the search result of the national language dictionary or the Hanwa dictionary for the character is displayed on the screen. It will be.

  According to the present embodiment, a desired character can be easily input simply by counting and inputting the number of vertical lines, horizontal lines, diagonal lines, and other lines.

  In the above embodiment, candidates are displayed for the first time by clicking a button 402 after inputting a stroke input character string in the text box 401. However, this embodiment changes this point.

  Further, in the present embodiment, when an input for a part of a Chinese character is completed, it is easy to determine whether or not the input for that part is correct.

  In the stroke input in the above embodiment, the number of each of vertical lines, horizontal lines, diagonal lines, and other lines can be specified. However, in this embodiment, a “separator” can be input. To do. In this embodiment, a blank character is used as a delimiter.

  For example, let us consider a case where a character “shin” (h6v3d1) is input. This character can be divided into two parts, “a” (d1v1) and “word” (h6v2), even for beginners.

  For beginners, it is often desirable to be able to enter text while checking the shape of each part.

  Therefore, in this embodiment, the stroke input is divided for each part such as “d1v1” and “h6v2”, and the entire character search and the part-by-part search are performed simultaneously. As a method for delimiting, a combination of a plurality of text boxes and buttons may be prepared, or only one text box may be prepared and delimited by a blank character.

  In the present embodiment, a character shape that is not prepared as a single Kanji character is also stored as “character” in the storage unit 202 in association with the stroke information. It is desirable to prepare and display “basic” and “radical” as attributes in the search for each part, and display “basic” and “ambiguous” as attributes in the entire search.

  Hereinafter, a description will be given focusing on differences from the above embodiment. FIG. 8 is an explanatory diagram showing a state of search according to the present embodiment. Hereinafter, a description will be given with reference to FIG.

  As shown in FIG. 5A, a combination of a plurality of text boxes 401 and buttons 402 is prepared in the vertical direction on the display screen. Although three sets are displayed in this figure, this number may be increased as appropriate.

  The combination of the text box 401 and the button 402 is for searching for and displaying “parts” of characters.

  First, when “d1v1” is entered in the text box 401 and the button 402 on the right side is clicked, the display changes as shown in FIG. In the partial candidate display area 403 on the right side, “I” and “卜” are displayed as candidates. Among these, “I” is a radical candidate (candidate with attribute “radical”), and “卜” is a basic candidate (candidate with attribute “basic”). The basic candidates are underlined, that is, different attributes are displayed in different styles. It is also possible to input a basic candidate as a character by clicking directly on the underlined item.

  In addition, “卜” and “亅” are displayed as candidates in the character candidate display area 404. Among these, “亅” is an ambiguous candidate (candidate with the attribute “ambiguous”) and is displayed small. These are also underlined, and can be directly clicked to enter them as characters.

  Also, the total stroke display area 405 displays the normal form “v1d1” of the total sum of the stroke input lines input so far.

  By the input so far, the beginner can see that “I” is displayed in the partial candidate display area 403 and can start to input the next part with peace of mind.

  When “h6v2” is entered in the next text box 401 and the right button 402 is clicked, “word” is displayed as a basic candidate in the part candidate display area on the right.

  In addition, the total stroke display area 405 displays the normal form “h6v3d1” of the total sum of the stroke input lines that have been input so far, and the character candidate display area 404 has “Ming”, “Yester”, “Y” as basic candidates. Heavy, Shin, Emperor, Star, Shoulder, Fence, Akatsuki, Aoi, and Kei are displayed as ambiguous candidates. These are also underlined, and can be directly clicked to enter them as characters.

  By the input so far, the beginner sees that the “word” is displayed in the partial candidate display area 403, confirms that there is no mistake in the recognition of the character shape, and sequentially inputs the strokes of the parts. By doing so, it becomes possible to obtain the whole character “Shin”.

  Then, as in the above-described embodiment, by clicking a character displayed on the screen (underlined), the character is input.

  FIG. 9 is an explanatory diagram showing a schematic configuration of the character input device according to the present embodiment. Hereinafter, a description will be given with reference to FIG. In addition, the same code | symbol is attached | subjected to the element which fulfill | performs the function similar to the said embodiment.

  The character input device 201 includes a partial presentation unit 209 in addition to a storage unit 202, a stroke input reception unit 203, a conversion unit 204, a candidate presentation unit 205, a selection input reception unit 206, and an output unit 208.

  Here, as described above, the stroke input received by the stroke input receiving unit 203 further includes information for dividing the number of lines into character portions.

  FIG. 10 is a flowchart showing the flow of control of character input processing according to the present embodiment. Hereinafter, a description will be given with reference to FIG. In addition, about the element similar to the said embodiment, description is abbreviate | omitted suitably.

  When the process is started, the stroke input receiving unit 203 sequentially receives stroke input corresponding to the character portion (step S901).

  Next, a total stroke input is generated by adding up all the stroke inputs that have been input so far (step S902). For example, if the stroke input is to be separated by a space, the space may be removed. If a plurality of text boxes 401 are used, the character strings input to them may be connected.

  Furthermore, the conversion unit 204 converts each of the stroke input portions input so far into normal stroke information (step S903).

  Then, the partial presentation unit 209 obtains “characters” (which may be the same shape as the basic candidate or may be a radical candidate) stored in the storage unit 202 in association with each piece of stroke information. (Step S904) and present it as a part (step S905).

  Furthermore, the conversion unit 204 converts the generated stroke input into normal stroke information (step S906).

  Then, the candidate presentation unit 205 acquires characters stored in the storage unit 202 (step S907), and presents them in a different style depending on whether this is a basic candidate or an ambiguous candidate (step S908).

  Next, the selection input receiving unit 206 determines whether or not there has been a selection input, that is, whether or not any candidate character has been clicked (step S909). If not (step S909; No), the process returns to step S901. .

  If there is a selection input (step S909; Yes), the output unit 208 outputs the selected candidate character (step S910), and the process ends.

  As described above, the part presentation unit 209 divides the accepted stroke input for each character part, and for each part, information indicating the number of vertical lines, horizontal lines, diagonal lines, and other lines of the part. The character stored in the storage unit 202 in association with the stroke information obtained by the conversion by the conversion unit 204 is presented as a part.

  Thus, the CPU 102 functions as the partial presentation unit 209 in cooperation with the RAM 103, the hard disk 104, and the like.

  Further, the stroke input receiving unit 203 converts the entire stroke input into the conversion unit 204 and displays it on the candidate presentation unit 205, and also converts the stroke input part into the conversion unit 204 and displays it on the partial presentation unit 209. To make it happen.

  In both of the above-described embodiments, each time the button 402 is pressed, the part or the whole is converted into the normal form and candidates are searched and displayed. However, each time the text box 401 is changed, the part is changed. Alternatively, conversion to the entire normal form and search and display of candidates may be performed. In this case, the button 402 becomes unnecessary. In this embodiment, when a high-speed search is possible, it is possible to immediately respond to the trial and error of the user, so that the learning effect of the beginner can be increased.

(Experimental result)
For 6 Japanese and 12 foreigners who are beginners of Japanese who can read simple kanji, 3 sets of the same number of strokes for 1 set and 5 sets for each of the sets An experiment was conducted in which one kanji character was randomly selected and entered, and the average per character was measured.

  According to the conventional stroke number input method, the Japanese had 34.7 seconds and 0 retries, and the foreigner had 104.8 seconds and 0.5 retries.

  On the other hand, in the method according to the above [Example 1], the Japanese time was 56.6 seconds and 0.5 retries, and the foreigner time was 62.4 seconds and 0.7 retries.

  Thus, although the input speed is slightly reduced in Japanese who have a high level of proficiency in Japanese, no significant deterioration has been observed, while on the other hand, the input speed has been greatly improved in Japanese beginners.

  As described above, it has been found that by following the principle of the present invention, it is possible to input characters efficiently.

  As described above, it is possible to provide a character input device 201, a character input method, and a program suitable for a learner such as Japanese or Chinese to input characters efficiently.
