Description

A Chinese character input method

technical field

The invention relates to the technical field of Chinese information processing, in particular to a computer Chinese character input method.

Background technique

How to input Chinese characters into computers has always been an important problem. There are many ways to input Chinese characters at present, which can be roughly divided into two categories: one is to encode Chinese characters, and then input the corresponding codes of Chinese characters into the computer through computer input devices (such as keyboards, mice, etc.) to achieve the purpose of inputting Chinese characters The other is to use the method of pattern recognition to recognize handwritten Chinese characters, printed Chinese characters or Chinese character pronunciation, so as to input Chinese characters into the computer. Although many Chinese character pattern recognition methods have a high recognition rate, there is always the problem of inaccurate recognition when using pattern recognition methods to input Chinese characters. Use the encoding method to input Chinese characters, and the different encoding methods will cause great differences in the input efficiency, ease of use, etc. of the Chinese character input methods. Some encoding methods have high input efficiency, but are not easy to use, and some are just the opposite. On a computer with a standard keyboard, the Chinese phonetic alphabet coding input method is the most widely used method, and its main reason is that the Chinese phonetic alphabet coding method is simple and easy to use. But, owing to being subjected to the limitation of display and input equipment size, on mobile computer equipments such as palmtop computer and mobile phone, Chinese phonetic alphabet coding input method becomes difficult to use. The most convenient Chinese character input method used on such devices is the online handwritten Chinese character pattern recognition method, but the pattern recognition method always has the problem of inaccurate recognition, and completely writing the entire Chinese character itself is not a fast input method.

Contents of the invention

The purpose of the present invention is to provide a Chinese character input method which is very suitable for inputting Chinese characters on mobile computer devices such as handheld computers and mobile phones, and the input method is simple and fast.

The Chinese character input method of the present invention is: the Chinese character coding is by the sequence that five kinds of basic strokes of horizontal, vertical, left, right (dot), folding are formed according to Chinese character stroke writing order, by this Chinese character coding input computer to reach the Chinese character input purpose of the computer. The method includes: a method for performing an operation prompt through the operation prompt area (as shown in accompanying drawing 4) and an operation method for using a positioning input device to perform stroke input; the operation prompt is passed through the stroke area (as shown in accompanying drawing 5) and the Chinese character candidate area ( As shown in accompanying drawing 3) to complete, according to the operation prompt, use the positioning input device to manipulate the cursor to click or draw a line in the operation prompt area to complete the input of basic strokes and auxiliary symbol sequences; according to the input sequence, use the known The method searches the stroke writing sequence dictionary of Chinese characters, finds the corresponding candidate Chinese characters, and arranges the candidate Chinese characters in the order of the frequency of use from high to low according to the position and arrangement of the Chinese character candidate areas (as shown in Figure 3) The corresponding position of the candidate area, while using different colors to identify the currently input strokes, the strokes being input, the skipped strokes and the strokes that have not been input in the Chinese character glyphs in the candidate area; click or draw on the candidate Chinese characters Line operation, the result of the operation is to input the operated Chinese character.

The stroke area (as shown in accompanying drawing 5) is made of basic stroke area (as shown in accompanying drawing 2) and auxiliary symbol area (as shown in accompanying drawing 1), and basic stroke area is made of five fan-shaped basic stroke blocks of the same size , each block is symmetrically distributed in the center, corresponding to the clockwise order: "horizontal", "vertical", "skimming", "捺 (dot)", "fold" five basic strokes (among them, "捺" and "dot) "Classified into the same type of basic strokes "捺"), respectively use the symbols "一", "丨", "ノ", "丨", "フ" to identify, and each block is closely connected to form a complete circular area. The basic stroke area is used for stroke input prompts. Operate the basic stroke block "一" to indicate the input of the basic stroke "horizontal"; operate the basic stroke block "丨" to indicate the input of the basic stroke "vertical"; operate the basic stroke block "ノ", Indicates the input of the basic stroke "插"; the operation of the basic stroke block "丝" represents the input of the basic stroke "捒(dot)"; the operation of the basic stroke block "フ" represents the input of the basic stroke "fold".

The auxiliary symbol area is used to assist the prompt of the basic stroke input function. The auxiliary symbol area contains auxiliary blocks corresponding to the five symbols "?", "*", "□", "■", and "←", among which "?" and " *" is a wild card, "?" means input any basic stroke, "*" means input any number of basic strokes, "□" means clear the basic strokes that have been input and start input again, "■" means input before The stroke in is the last stroke, and "←" means to delete the stroke just entered.

Under the prompt of the stroke area, the methods of using the positioning input device to operate in the basic stroke area, auxiliary symbol area and Chinese character candidate area are as follows: (1) use the positioning device to draw a line, if the drawn curve passes through the basic stroke area each basic stroke block, the operation has input the basic stroke corresponding to the basic stroke block; if the drawn curve passes through the auxiliary block in the auxiliary symbol area, then the operation has input the symbol or expression operation represented by the auxiliary block; Draw a curve through the candidate Chinese character block in the Chinese character candidate area, then this operation has input the candidate Chinese character represented by this Chinese character block; If the curve passes through the basic stroke block again after leaving the basic stroke block, then this operation has input the corresponding basic stroke again; 2) Use the positioning device to click inside the basic stroke area, auxiliary symbol area or Chinese character candidate area, indicating that the operation expressed by the corresponding basic stroke or auxiliary symbol area in this area or the corresponding candidate Chinese character is input; the line drawing operation can be input one at a time or For multiple basic strokes, click to input one basic stroke at a time, and the two operations can be used in any combination.

Operate the stroke area, input the corresponding basic strokes and auxiliary symbols or auxiliary action sequences, use the input sequence, use known methods to search the stroke writing sequence dictionary of Chinese characters, find the corresponding candidate Chinese characters, and place the candidate Chinese characters in the Chinese character candidate area displayed within. When the candidate Chinese characters are displayed, different colors are used to identify strokes that are currently input, strokes that are being input, strokes that are skipped and strokes that have not yet been input in the Chinese character glyphs in the candidate area.

The positions and arrangements of the candidate Chinese characters in the candidate Chinese character area are shown in Figure 3. The Chinese character candidate area comprises nine candidate Chinese character blocks (marked the positions of the candidate Chinese character blocks 1-9 with numbers 1-9 in the accompanying drawing 3) and two page-turning blocks, and all candidate Chinese character blocks are square regions, and the candidate Chinese character blocks 1 is located in the center of the Chinese character candidate area, and the remaining eight candidate Chinese character blocks are distributed around the four sides of the candidate Chinese character block 1, closely connected with each side of the candidate Chinese character block 1, and the side length is half of the candidate Chinese character block 1; Candidate Chinese character block 2 and candidate Chinese character block 3 are on the left of 1, and candidate Chinese character block 2 is below candidate Chinese character block 3; above candidate Chinese character block 1 are candidate Chinese character block 4 and candidate Chinese character block 5, and candidate Chinese character block 4 is at the candidate The left side of the Chinese character block 5; the candidate Chinese character block 6 and the candidate Chinese character block 7 on the right side of the candidate Chinese character block 1, the candidate Chinese character block 6 is above the candidate Chinese character block 7; the candidate Chinese character block 8 and the candidate Chinese character block 1 are below the candidate Chinese character block 1 Chinese character block 9, candidate Chinese character block 8 is on the right side of candidate Chinese character block 9; the lower left corner and the lower right corner of the Chinese character candidate area are respectively provided with "<<" page turning block and ">>" page turning block, which are respectively used to turn forward page and page backward.

Candidate Chinese characters are divided into two categories: Candidate Chinese characters that completely match the input strokes and Chinese characters that partially match the input strokes. The exact expression of complete match and partial match sees the code fragment 1 of embodiment, and wherein " find_exact " method is to find the C++ programming language method of completely matching candidate Chinese character, and " find " method is the C++ programming language method of finding partial match candidate Chinese character . One candidate Chinese character is displayed in each candidate Chinese character block, and the candidate Chinese characters are displayed in the candidate Chinese character blocks 1-9 in the following order: First, the exact matching Chinese characters are listed in order of Chinese character usage frequency from high to low, and then in order of Chinese character Partially matched Chinese characters are listed in order of frequency from high to low; when the number of candidate Chinese characters is greater than nine, the candidate Chinese characters will be displayed in pages, and the "<<" page turning block in the lower left corner of the Chinese character candidate area and the "" in the lower right corner ">>" page turning blocks are used to turn pages forward and backward respectively.

When inputting Chinese characters according to the written stroke order of Chinese characters, you can input all the strokes of the Chinese characters completely according to the stroke order, you can also skip some strokes and continue to enter the rest of the strokes, and you can also perform fault-tolerant processing on some strokes that are prone to errors, allowing the same Chinese character Corresponds to various stroke sequences.

Compared with the prior art, the present invention is more suitable for using a stylus to input Chinese characters on computers with small screens such as handheld computers and mobile phones, and does not need to write the entire Chinese characters, and has the advantage of being simple to use. The invention is also applicable to general computer equipment.

Detailed ways

The concrete embodiment that uses Chinese character input method of the present invention to input Chinese character is as follows:

1. Display the operation prompt on the computer display device (or directly print the stroke area in the operation prompt in advance on the input panel of the input device), the operation prompt is composed of the stroke area and the Chinese character candidate area, and the stroke area includes the basic stroke area (such as shown in accompanying drawing 2) and auxiliary symbol area (as shown in accompanying drawing 1);

2. Use positioning devices, such as stylus, mouse, pressure-sensitive pen, light pen, etc., to manipulate the cursor to click or draw lines in the stroke area of the display device, and the traces of the operation are displayed in the corresponding area in real time, as shown in Figure 7 to Shown in accompanying drawing 11 (if the stroke region is to be printed on the input panel of input device in advance, be to manipulate the stroke region on the input panel to operate the positioning device, and the trace of operation does not show). The click operation is slightly different depending on the specific positioning device. The click operation of the pen-type positioning device means that the pen tip falls, touches the writing surface, and then lifts the pen tip; the click operation of the mouse-type positioning device refers to pressing the mouse. button, and then release the mouse button. For a pen-type positioning device, the line-drawing operation refers to: drop the pen tip, touch the writing surface, move the pen tip, and then lift the pen tip; the line-drawing operation of the mouse-type positioning device refers to pressing the mouse button, moving the mouse cursor , release the mouse button. The implementation method of the above operation mode is a well-known method in the field.

3. The operation on the basic stroke area represents the input of the corresponding basic strokes. For example, the operation shown in accompanying drawing 7 is to click on the basic stroke area "one" to indicate the input stroke "horizontal"; the operation shown in accompanying drawing 8 and accompanying drawing 9 For the line drawing operation, the drawn curve passes through the basic stroke areas "one" and "丨", indicating the input stroke sequence "horizontal" and "vertical"; the operation shown in Figure 10 is a line drawing operation, and the drawn curve passes through the basic strokes Districts "一", "丨", "ノ", "严" represent the input stroke sequence "horizontal", "vertical", "left" and "捷"; the operation shown in accompanying drawing 11 is a line drawing operation, so Drawing a curve passes through the basic stroke areas "一", "一", "丨", "一" to represent the input stroke sequence "horizontal", "horizontal", "vertical" and "horizontal".

4. Use the input stroke sequence to look up the stroke writing sequence dictionary of Chinese characters, and the found Chinese characters are displayed in the Chinese character candidate area, as shown in Figures 7, 8, 9, 10, and 11. The realization of the stroke writing sequence dictionary of Chinese characters is a well-known method in the art, and the method of looking up the dictionary is also a well-known method in the art. Code snippets 1 and 2 provide an implementation method. By using "*" and "?" in the auxiliary symbol area and adding different strokes of the same Chinese character in the dictionary, you can enter all the strokes of the Chinese character in the order of strokes, or you can skip some strokes and continue to enter the rest , and can also perform fault-tolerant processing on some error-prone stroke sequences. "?" means to input any basic stroke, and "*" means to input any number of basic strokes. The standard C++ programming language source program code of the dictionary search algorithm supporting "?" and "*" is shown in code fragment 1.

5. Display the found candidate Chinese characters in the Chinese character candidate area, and use different colors to identify the Chinese character glyphs displayed in the Chinese character candidate area according to the strokes that have been input, are being input and have not been input, and use "Yong" Take the word as an example, as shown in Figure 6. When inputting the basic strokes "捕 (point)", the "Yong" word displayed in the candidate area is shown in the first Yong character from the left among Fig. 6; The character "Yong" is shown as the second character from the left in Figure 6; when continuing to input the basic stroke "fold", the character "Yong" displayed in the candidate area is shown in the third character from the left in Figure 6 When continuing to input the basic strokes "插", the "Yong" word displayed in the candidate area is shown in the fourth Yong character from the left in Figure 6; The word "Yong" is shown in the fifth word "Yong" from the left in Figure 6. A method for realizing the above function is: for each Chinese character, make all possible stroke glyph data of different colors, search for these glyph data according to the input strokes, and find the corresponding data for display. Taking the character "Yong" as an example, the five glyph data shown in Figure 6 are prepared for the character "Yong", and the corresponding glyph data is selected for display according to the input strokes.

6. Click or draw a line in the Chinese character candidate area, the selected Chinese character is the Chinese character to be input.
