Description

Matrix Chinese character input method and device

technical field

The invention relates to a method and device for inputting Chinese characters, in particular to a method for inputting Chinese characters via electronic products such as computers and telephones.

Background technique

Compared with other languages, such as English, Japanese and Korean, it is more difficult to enter Chinese characters into electronic media (such as computers and telephones). This is because Chinese is derived from pictographs and consists of multiple parts, plus There are many strokes on it, so it is not convenient to use the general Chinese input method.

There are many technical solutions related to using computers to input Chinese characters at present. For example, adding the Chinese character database into the hardware, or installing the Chinese character database into the memory of the computer via a CD, Chinese characters can be input through the predetermined program of the computer. Now, there are already hundreds of computer input methods for Chinese characters, and each method has its characteristics and advantages, but there is a common disadvantage, that is, the input speed is slow, and it takes more than ten keys or even the entire standard keyboard to write enter. Moreover, the user must keep in mind many radicals of Chinese characters and methods of decomposing Chinese characters, so it is difficult to learn and remember how to use them.

For example, common Chinese character input methods include: font input methods (such as Cangjie code or simple code), the advantage is that there are fewer repeated codes, and the disadvantage is that multiple keys are needed, so this type of method is not suitable for mobile phones. In addition, users need to learn how to Divide the text into small parts; the pinyin input method has the advantage that it can be used only by knowing the correct pronunciation, but the disadvantage is that it is difficult for users to accurately piece together the pronunciation of Chinese characters with English letters, especially if the pronunciation of Mandarin is not standard Users, such as the nine tones of Cantonese, will increase the difficulty accordingly; the code input method has the advantage of avoiding repeated codes and only needs to press four digits, but the disadvantage is that it is impossible to remember the code of each Chinese character; the stroke input method has the advantages of Input in the most instinctive way, just like writing, the disadvantage is that you need to press the keys many times, and there is also the problem of repeated codes.

With the increasing demand for Chinese in computer and communication technology, it is really necessary to find an input method that is simple and convenient. At the same time, it must avoid the previous mechanical reciting, easy to learn and require fewer keys on the keyboard, and The input method can also be applied at the level of computer technology, messaging, Internet and Intranet technology.

Detailed ways

According to an embodiment of the present invention, the Chinese character input method is a vector-type stroke input method, that is, a method in which strokes are input according to whereabouts of the strokes. 6 stroke direction keys are used to represent 6 different directions of the stroke, one represents from top left to bottom right, one represents from top to bottom, one represents from top right to bottom left, one represents from left to right, and one represents from bottom left to top right , one for more than one direction in the stroke. The user presses the keys in stroke order, and each key represents a stroke, so the number of key presses is equal to the total number of strokes. But as the key is pressed, the control program will search for matching Chinese characters, and will list them horizontally on the display screen according to the total number of strokes. If the number of matching Chinese characters is too large, they cannot all be listed horizontally on the display screen, and the remaining Chinese characters will be arranged in the "next page" list. The user can use the "Next Page" function key to enter the "Next Page" menu. When the desired Chinese character is displayed on the display screen, the user can use the left and right direction movement keys to move the cursor on the display screen to the desired Chinese character, and then press the OK key to input the Chinese character.

According to another embodiment of the present invention, the Chinese character input method is the homonym character input method (voice code), that is, only the homonym character needs to be input, and the control program will search for the Chinese character with the same phonetic symbol in pinyin, and according to the total number of strokes, from less to more Listed vertically on the display from bottom to top. The user can use 4 search homophone keys (up, down, left, right) and 2 function keys (next page, confirm) to assist input. This input method can be used to input Chinese characters with relatively simple strokes, such as "liang" to input the character "grain". This input method can also be used when the correct way of writing the character is forgotten.

The Chinese character input device (as telephone and computer) of the present invention must be equipped with a keyboard such as 12 keys, central processing system, storage device and display screen. The central processing system and the storage device should already include a Chinese character library, a matrix input method database and a control program. These databases and control programs will be preloaded in the computer, or imported into the computer from a storage medium (such as a CD).

The (next page) key will be placed on the "6" key, and the "√" key will be placed on the "Enter" key.

Fig. 2 shows an example of the Chinese character input process according to the embodiment of the Chinese character input method of the present invention. For example, when using the vector stroke input method as the input method to input the word "moment", press the keys according to the order of the strokes: press a key representing from upper right to lower left, press a key representing from left to right, press a key representing from Left to right key, press a key to represent from top right to left, press a key to represent from top left to bottom right, press a key to represent from left to right, press a key to represent from top to bottom , press a key that represents more than one direction in the stroke, press a key that represents left to right, and press a key that represents left to right. Press the key ten times in total (the number of key presses will be equal to the total number of strokes). Take the phone button as an example, that is, 3443142944.

FIG. 3 shows another example of the Chinese character input process according to the embodiment of the Chinese character input method of the present invention. For example, inputting the character "梁" with the vector stroke input method, that is, the method of inputting the strokes according to the direction of the strokes. Press the keys according to the order of the strokes; press a key that represents from top left to bottom right, press a key that represents from top left to bottom right, and then press the next key that represents from bottom left to top right, press a key that represents more than one stroke in the stroke A direction key, press a key representing from top right to bottom left, press a key that represents from top left to bottom right, press a key that represents from top left to bottom right, press a key that represents from left to right key, press a key representing more than one direction in the stroke, press a key representing up-right to down-left, and press a key representing up-left to down-right. Press the key 11 times in total (the number of keystrokes will be equal to the total number of strokes). Take the phone button as an example, namely 11793114931.

FIG. 4 shows a simulation diagram of a user interface using a matrix input method written in JavaScript on a mobile phone platform. The user interface is displayed on the display screen. The display screen can simultaneously display a plurality of Chinese characters in a matrix form, for example, 6 characters in a horizontal row and 6 characters in a vertical column. There are 10 characters in the horizontal row in Fig. 4 and 16 characters in the vertical column.

键(即光标在横排向右移动7次，直到“梁”字)，这时程序便会再次翻查数据库并列出所有跟“梁”字同音的字元。使用者便能以“、▲”键在纵列汉字中勾选所要的字元。同样，“短”字可以按入344314294134，但在已按入34431429时，显示屏会同时显示“矩”字(3443142944)及“短”字以供选择(所有共享同样起首数码的字元都会依数码的总长由左至右排列出)。于是可再按

键及“√”键来确定。当然按入键越多，字元的选择便越狭窄及准确。否则可能要按(下一页)键来浏览字元的选择。When the user has keyed in the stroke key code 14793, the program will search the database and list all characters starting with 14793. The user then types 7 times in a row

key (that is, the cursor moves to the right 7 times in the horizontal row until the word "Liang"), at this moment the program will search the database again and list all characters that have the same pronunciation as the word "Liang". Users will then be able to " , ▲" keys to check the required characters in the vertical Chinese characters. Similarly, the word "short" can be pressed into 344314294134, but when 34431429 has been pressed, the display screen will simultaneously display the word "moment" (3443142944) and the word "short". " for selection (all characters sharing the same initial number will be arranged from left to right according to the total length of the number). Then press

key and "√" key to confirm. Of course, the more keys are pressed, the narrower and more accurate the character selection will be. Otherwise you may have to press (Next page) key to browse the selection of characters.

Fig. 5 shows the establishment of the vector stroke input method database used in the embodiment of the present invention. The vector stroke input method database (Vector Stroke Database, VSD) is established like a tree structure (VSD tree). Each key press is represented by a cell. And the data recorded by each unit will be different due to the number of strokes contained. If the cell represents a character, the cell is a "leaf cell". If the cell does not represent any character, the cell is an "intermediate cell". The most basic structure of a unit is composed of 8 bits (bit). The first three bits represent the number the user just typed. Because the Chinese character input system of the embodiment of the present invention only uses " 1 ", " 2 ", " 3 ", " 4 ", " 7 ", " 9 " and " do not have any input (Nil) " altogether seven combination keys, so Three bits can already contain these seven choices (three bits represent 2 ³ , ie eight choices). The fourth to eighth bits represent how many units to expand down. Since there are five bits to represent, there can be up to ²⁵ (ie 32) units.

Figure 6 depicts an example of a cell structure. As shown in the figure, assuming that after pressing the "2" and "4" keys after "Start", it will lead from #2 unit to #16 unit, and #2, #16 and #102 units are all intermediate units . The total length of the intermediate unit depends on how many lower units there are, and each additional lower unit will increase 2 bytes. Units #103, #104 and #105 are leaf units. The leaf unit will record the represented characters in 2-bit bytes.

√”键来勾选所要的字元。Fig. 7 depicts an example of a vector-based stroke input method database. When the user keyed in the first digit of the code, the control program began to look up all characters starting with the digit. As more digits are entered, fewer characters are covered. If the database has only the following characters "liang, 忍, cool, ranunculus, niang, cool, beam, buttercup, quantity, starling, grain, beam, 跳, 綡, beam, partridge, 辌, 駺, grain", when inputting the number "1", the characters "liang, liang, liang, liang, liang, liang, liang" will be screened out. After keying in the number "1", only characters such as "liang, liang, liang" will be checked out. As more digits are entered, fewer characters are listed in the character list. The user can then select the "

√” key to check the desired character.

键在选表单内移动光标以勾选所要的字元时，该字元会反白或转色(如图4下方横排的小方框中的“梁”字)。这时使用者便可以用“√”键在该字元所同音的字元(纵列汉字)中以“

、▲”键勾选所要的字元。At the same time, when the user starts with

When using the key to move the cursor in the selection form to check the desired character, the character will be highlighted or turned in color (as shown in the "beam" word in the small horizontal box at the bottom of Figure 4). At this time, the user can use the "√" key to use the "√" key in the character (vertical Chinese character) that is the same as the character.

, ▲” keys to select the desired character.

Figure 8 depicts an example of concatenated sorted pronunciation groups in the homophone database. The Voice Code Database (VCD) is composed of a linked list and an array structure. Concatenation sorting will restrict the system to sort out the pronunciation order of each character. The array structure allows the system to guide in multiple directions.

(1) Series sorting pronunciation groups

Concatenation sorting will restrict the system to sort out the pronunciation order of the character "上", that is, the 3004th and 3202nd pronunciation groups.

(2) Array structure

The array structure records the characters contained in the same pronunciation group. For example, the 3202nd pronunciation group (soeng6) contains two characters of "up" and "shang".

FIG. 9 depicts a flow chart of the matrix input method according to an embodiment of the present invention. During the Chinese character input process, the stroke direction keys pressed by the user will be recorded in the memory, and the records will be cleared only after there are already input characters. When the user presses the stroke direction key, the system will first search the tree structure (VSD tree) of the vector stroke input method database. And as the user continues to press keys, the midway unit and the leaf unit are searched downwards all the time. When the system is searching for leaf units that expand downward, several Chinese characters with the smallest width (determined in advance according to the size of the display screen) will be listed on the display screen. And according to the width of the leaf unit (ie the total number of strokes), the selection list on the display screen is listed horizontally from the least to the most. As more keys are pressed, the searched unit gets deeper into the tree structure and closer to the desired character. Simultaneously, searching Chinese characters according to this method can shorten the number of key presses. Because several intermediate units in front of many leaf units have not branched out other leaf units.

After a pause for some time (for example, 0.5 seconds by default), the system will search the homophone character database (VCD). The pronunciation group of the character will be searched by concatenation sort first, and the characters contained in the same pronunciation group will be pointed out in the array structure. The indicated characters are arranged in a column on the display. The user then needs to type 'up▲''down

'Search the homophone key to check the desired character. The program will display the character in white or in color. The user presses the '√' (OK) key to input the checked characters.

、▲”键以选择及“√”键来确定。The user uses the database of homophones, even when he forgets the wording, he can still continue to input. It is also possible to avoid lengthy typing of multi-stroke words. For example, the word "Liang" is input with the homophone input method. You only need to input homophones with simpler strokes, such as "liang" (the stroke key code is 1944931), because all homophones will be listed from bottom to top, so you can press "

, ▲” key to select and “√” key to confirm.

If the hardware keyboard has multiple keys available, the system allows other keys to be used instead of the search homonym key, for example, use 'F1' to represent the first word listed in the selection list, and use 'F2' to represent the second word listed in the selection list. Select the words in the form, etc., and the input speed will be faster.

According to the Chinese character input method and device of the present invention, all Chinese characters can be easily input. The Chinese character input method of the present invention does not need to study for a long time, and does not need to recite the method of splitting characters or radicals of Chinese characters. After a short period of learning, the user can input thirty Chinese characters per minute, which is close to the speed of inputting Chinese characters by handwriting on a computer. The system requirements are very simple, as long as a phone's keyboard and screen can be used to input Chinese characters, especially very suitable for today's mobile phones.
