Then, the user selects a desired final Chinese character among the displayed characters via the key input module(10).

Description

Chinese character input processing method and apparatus {PROCESSING METHOD AND APPARATUS FOR INPUTTING CHINESE CHARACTER}

The present invention relates to a method and apparatus for inputting Chinese characters, and more particularly, an apparatus for inputting Chinese characters to an electronic device such as a mobile communication terminal or a computer using an input device such as a dialing keypad or a computer keyboard, and input thereof. The present invention relates to a method for processing a signal and receiving a Chinese character.

Chinese is a ideographic letter unlike English or Korean phonetic letters, and because it has tens of thousands of characters, computers, portable computers, set-top boxes, telephones, mobile terminals, personal mobile terminals, personal mobile terminals, wireless Characters cannot be assigned one-to-one on the keyboard of wired / wireless terminals such as data terminals, common frequency communication terminals, smart phones, and automatic control devices.

Therefore, the conventional method for inputting Chinese using a computer keyboard or the like is largely the following two methods.

The first conventional method is a method called "Chinese Pinyin input method" in which the Chinese pronunciation is inputted in English regardless of the tone when inputting Chinese. Here, the Chinese Pinyin refers to writing a Chinese character which is a Chinese character as a phonetic symbol using an alphabet letter.

However, because only English pronunciations are represented, there are too many Chinese characters with the same pronunciation, so each time you enter a letter, you have to select the Chinese characters you want to input from among the many Chinese characters (several dozens) with the same pronunciation. Therefore, it is difficult to input Chinese characters at a high speed because much time is wasted in this process.

The second conventional method is a method of separating Chinese characters into phoneme units and combining Chinese characters by inputting a combination of keyboards corresponding to each phoneme. A method called "five-letter type input method" is an example of that type.

However, there is a problem that it is difficult for ordinary people who are not experts in inputting Chinese characters to learn and use. In other words, if you look at the Chinese characters as a whole, the complicated structure takes up a large number. The process of separating such Chinese characters into phonemes is difficult and complicated, so it is not easy for the general public to understand and use the rules. In addition, it is difficult to memorize and properly use combinations of keyboards because there are several (up to 12) phonemes assigned to each keyboard. Therefore, in order to input Chinese smoothly using this method, there is a problem that requires a long time of effort and training.

In addition, the "Chinese computer input method" proposed in Korean Patent Laid-Open Publication No. 1983-0003768 indicates that Chinese characters are horizontal, vertical, braille, oblique, clockwise, counterclockwise, right and left. Dividing the stroke into a stroke, giving the strokes an equivalent number of 1, 2, 3, 4, 5, 6, 7, and 8, respectively, prioritizing the equivalent numbers from top to bottom, Inputting the stroke from the left to the right into the input system according to the sequential order of the kanji composition, and if the clockwise stroke, the right turn stroke and the counterclockwise stroke, and the left turn stroke have two or more segments, the equivalent The floating numerals corresponding to the clockwise stroke, the right turn stroke and the counterclockwise stroke, and the left turn stroke of the segment are added to the numbers.

However, since the Chinese characters are input according to the same number of strokes as the strokes of the Chinese characters, when entering Chinese characters having a large number of strokes, a large amount of time is wasted.

The present invention has been proposed in order to solve such a conventional problem, and it is possible to classify the characteristic forms of Chinese characters into a predetermined number of representative features and to assign the identification factors correspondingly, respectively, and then input a part of the Pinyin alphabet of Chinese characters and desired Chinese characters. An object of the present invention is to provide a Chinese character input device capable of inputting a corresponding Chinese character by combining an identification factor corresponding to a representative feature of.

Another object of the present invention is to provide a Chinese character input processing method for recognizing a corresponding Chinese character that requires input from Chinese characters based on alphabet information and identification factor information input through the Chinese character input device.

According to the present invention, it is possible to improve the character input speed by reducing the number of input strokes compared to other Chinese input methods in the related art, and if you know only some alphabets of the Pinyin, It is possible to easily input desired Chinese characters by extracting representative features from. In addition, the method of inputting Chinese characters into all electronic devices can be unified, thereby eliminating problems such as input error or mastery delay caused by using different methods.

According to one aspect of the present invention for realizing the above objects, the Chinese character input processing method includes receiving at least one or more alphabet information among the Pinyin alphabets of Chinese characters that require input, and representing a predetermined number of characteristic forms of the Chinese characters. Receiving the identification factor information corresponding to the representative feature of the desired Chinese character from among the same number of identification factors each classified according to a characteristic, and matching the received alphabet information and identification factor information among the Chinese characters; Extracting the Chinese character to recognize the desired Chinese character.

In another aspect of the present invention, a Chinese character input device is a Chinese character input device to which the above processing method is applied, and includes: a key input unit for inputting a combination of the pinyin alphabet information and identification factor information of a Chinese character that requires input by selection using a plurality of keys; And the memory in which the Chinese characters are databased with the pinyin alphabet information and the identification factor information, and the database is searched based on the input pinyin alphabet information and the identification factor information. And a controller for recognizing the kanji corresponding to the identification factor information as the desired kanji.

There may be a plurality of embodiments of the present invention. Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. This embodiment allows for a better understanding of the objects, features and advantages of the present invention.

The total number of Simplified Chinese in China is 189, and 186 are included in 3,500 commercially available Chinese characters. In the present invention, a total of 184 copies, except for those used only as a copying point (´) and a support, are classified into a total of 27 representative features according to the characteristic form appearing on the head of the upper part of the Chinese character. Hereinafter, the representative features extracted by the present invention will be referred to as "two-head features" for ease of explanation and understanding. Here, the number of Chinese copies is included in the Chinese character in the original character form or the modified (simplified) form, but in the present invention, regardless of the original form of the copies, it is based on the actual visible state, that is, the modified character form. Extract two features.

Hereinafter, a description will be given of a process of extracting two types of features from Chinese kanji according to the present invention.

Some Chinese kanji form independent Chinese characters, while others form one Chinese character. In addition, the number of copies is arranged in the left and right, the top and bottom, the left and the top, the left and the bottom, and the whole enclosed. As described above, two types of Chinese characters are extracted from various Chinese characters, and the location of the two types of features may be questioned. Therefore, a consistent extraction method is important.

The two-headed feature extraction method according to the present invention is to be extracted from the number of copies located at the top or one side of the Chinese characters, and based on this, all Chinese kanji have one headed feature only at one of the top or one side, and the top and one side. Chinese characters with two two-headed features are separated.

In Figure 1 attached, a total of 27 head type features representing the head type characteristics of Chinese kanji according to the present invention are shown. The identification features similar to those of each type were assigned to each of the two types of features, and each of the representative Chinese kanjis having the two types of features was matched and borrowed as the title of the identification factor. This is to help the convenience and understanding of the description of the present invention, and to distinguish the two features as sound as well as form in the actual application process of inputting Chinese using a computer keyboard or a dialing keypad of a mobile communication terminal.

2a to 2c summarize the number of copies belonging to the two types of features classified into a total of 27 types based on the two features feature extraction method according to the present invention. In addition, in the corresponding character, the Chinese characters are difficult to extract the two head features. If the characteristic form of the Chinese character is not completely consistent with the 27 kinds of head features, the most similar head feature is extracted as the head feature of the Chinese character.

As shown in Figures 2a to 2c will be described the corresponding number and the corresponding letters belonging to each of the two features.

The two features "grain, steel, system, rudder, yarn," and their corresponding parts have the same literal form.

Corresponding number and character from which the two features "un" are extracted correspond to the number and character of the form where the point is located on the top of the horizontal stroke.

The two feature "tea" corresponds to the number of copies and letters in the form of two points or two vertical strokes on the top of the horizontal stroke.

The two-character feature "mountain" corresponds to a character in the form of three point or vertical strokes located on the head or horizontal stroke, or three vertical strokes without horizontal strokes.

The two-type feature "work" corresponds to a letter in the form of an independent horizontal line or mingat head.

The two type feature "King" means an independent row or A character of the form in which one vertical or diagonal line is located at the bottom of the horizontal stroke included in the form.

The two feature "This" means independent horizontal strokes or It corresponds to a letter in the form of two vertical or diagonal vertical strokes below the horizontal stroke included in the shape.

The two-character feature "number" corresponds to an independent vertical stroke or a horizontal stroke to the right of the vertical stroke, or a letter or diagonal stroke to the left or right of the vertical stroke.

Two-character feature "ya" corresponds to the upper part of the letter in the form of two adjacent strokes.

The two-type feature "ten" corresponds to a character in which a horizontal stroke and a vertical stroke cross each other in the form of 十.

The two-shaped feature "neck" corresponds to a letter in the form of an oblique stroke at the bottom of a crossing of a twelfth form.

Two-character feature "gu" corresponds to the letter of the form 口 all around.

Two type "Wall" is not blocked on the bottom of one side This is the type of character.

Two feature "bag" is Mingat head or Characters of the form A character of the form where the stroke is located on the same line as the top or horizontal stroke.

The two type feature "Min" This corresponds to a text in which the left vertical stroke of the text containing the form is longer than the right vertical stroke.

Two-character feature "window" is the lower left part of the horizontal stroke or diagonal stroke or the horizontal stroke with a point at the top, and corresponds to the character in the form of the vertical stroke or the diagonal stroke.

The two-shape feature "degree" corresponds to the letter in the form of a vertical stroke or an oblique stroke at the lower right of a horizontal stroke.

The head feature "muscle" This is the type of letter that appears.

The two-character "arm" corresponds to a character in which the diagonal stroke is used independently or the vertical stroke does not start from the center bottom of the diagonal stroke.

Two-type feature "cloth" refers to a letter in the form of a vertical stroke or a diagonal stroke at the bottom of one or two diagonal strokes.

The two-type feature "juk" corresponds to a letter in the form of a horizontal stroke to the right of the diagonal stroke.

The two features "force" are horizontal strokes, Corresponds to the text in the form of an oblique vertical stroke with the end facing to the left crossing the horizontal stroke included in the form.

The two-character feature "nothing" is the horizontal stroke or Corresponds to the text in the form of an oblique vertical stroke with the end of the text facing to the right crossing the horizontal stroke included in the form.

As shown in FIGS. 2A to 2C, the Chinese copies or Chinese characters corresponding to the two type features 1 to 27 have the same or similar characteristics as those of each identification factor, so that the type features can be easily obtained from most of the corresponding characters belonging to each type. You will be able to extract it. However, some of the Chinese characters have room for overlapping in extracting two features, which will be described below.

Looking at the characteristics of the upper end of the two Chinese characters when extracting the two types of features of the US and the small, it can be seen that the diagonal strokes are located to the left and right of the vertical stroke. Here, the left and right diagonal strokes are regarded as two-shaped features, and the ones extending to the lower portion are excluded from the two-shaped features. In the US, the two-shaped feature "mountain" is extracted, and in the small (small), the two-shaped feature "water" is extracted. .

side( ) Corresponds to the two-headed feature "arm," which may be misclassified as the two-headed feature "cloth. However, the upper diagonal line and the lower end 米 are separated, and in particular, the pen type of the Simplified Chinese is drawn in a more separate form, so the sides ( ) Corresponds to the two-headed feature "arm".

Referring to FIGS. 2A to 2C as described above, it is possible to easily extract the head features of 3,500 characters commercially available, but to illustrate the technical spirit of the present invention more clearly, the following will illustrate the process of extracting head features for several Chinese characters. .

Here, when extracting the two-shaped features, in principle to extract from the number of copies located at the top or one side of the Chinese character, there are some Chinese characters having only one two-shaped features, but there are also Chinese characters having two or more two-shaped features.

<Single type Chinese character>

1. Chinese characters in general form

Chinese characters such as 거 (中), 中 (中), 京 (경), etc. are extracted from 십 (거) and 中 (中) based on the features appearing at the top. Extract the feature "un".

2. Chinese characters with two or more independent features at the top

2-1. Chinese Characters Taking Front Feature

生 (모두) includes both the features of the two-type feature "juk" and "two" feature, but takes the front feature to extract the two-type feature "juk", and 升 (seung) is the two-type feature "cloth" and two-type feature " It includes all the features of ten ", but extracts two feature" cloth "by taking the front feature, and 兜 (two) includes both features of" two "and" white "and" two ". However, it takes the front feature and extracts the two-shaped feature "window".

2-2. Kanji characterizing the back

武 (무) includes both the two-headed feature "one" and the two-headed feature "moo", but takes the back feature to extract the two-headed feature "moo", and 我 (h) has the two-headed feature "cloth" and two-headed feature " It contains all the features of "no", but extracts the two-shaped feature "moo" by taking the back feature, and 재 (jae) contains both the features of the "two" feature and the "two" feature, but takes the back feature Extract the feature "Nothing".

2-3. Kanji with top features

成 (sung) includes both features of the two-shape "window" and two-shape "moo", but takes the upper side feature to extract the two-shape "moo", and 皮 (blood) is the two-shape "window" and two-shape It includes all the features of "ten", but extracts the two features "ten" by taking the top feature.

<Plural head type Chinese characters>

1. Chinese characters in general form

1-1. Chinese character showing two independent features in the transverse direction

理 (Lee) extracts both the two-type features "king" because the feature of the two-type feature "king" appears in plural, and the case includes both the two-type feature "the cloth" and the two-type feature "the porridge". Since the head feature "cloth" and the head feature "juk" are extracted sequentially, the 建 (건) includes both the head feature "do" and the head feature "ten", so the head feature "do" and the head feature " Ten "is extracted sequentially, and the answer (答) is because the features of the two-shaped feature" juk "appears in plural, so the two two-type feature" juk "is extracted.

1-2. Chinese character showing three independent head features in the transverse direction

랍 (Lob) includes both features of "two" feature, "two" feature "window" and "two feature" porridge, but selects only the left and right features to produce both "two" feature and "two" feature. 도 (도) includes both features of "two" feature "cloth" and "two" feature "day" and "two" feature "ya", but selects only the left and right features, "two" feature "king" and "two" feature 추출 (Ryu) includes both features of the two-headed feature "neck" and two-headed "window" and two-headed "min", but by selecting only the left and right features, the two-headed "neck" and two-headed " Min "is extracted.

2. , , , , Chinese characters appearing at the bottom and one more head feature

차 (tea) Beginning with the features of the upper two features "car" and the lower two features "arm", so the two features "car" and two features "arm" is extracted, the shrine Beginning with the two features "bag" and two features "gu" in the top two features "bag" and two features "gu" to extract both, 病 (bottle) Beginning with the two-head feature "window" of the upper and two-head feature "king" of the lower part, so both the head feature "spear" and the two-head feature "king" are extracted.

3. , , , , Chinese characters appearing at the bottom and two more features of two types on the left and right

숙 (sook) Beginning with the two-head feature "bag" at the top and the two-sided features "cloth" and "king" features to the left and right, but taking the top and bottom features only the two-head feature "bag" and two-head feature "wang" , And 茄 Beginning with the two features "car" on the top and the two features "force" and "gu" on the left and right, but taking the features of the top and the bottom right features the two features "car" and two features "gu" Is extracted, and Beginning with the two features "car" on the top and the two features "window" and "porridge" to the left and right on the bottom, but taking the features of the top and the lower right, the two features "tea" and two features "juk" Extract

Looking at the two-head feature extraction process as described above , , , , Except for the Chinese characters that begin with, it is possible to extract only one head feature when multiple head features that are not independent from side to side appear, and to extract two head features when multiple head features separate from left and right appear. have. here , , , , An exception to extracting the two head features from Chinese characters beginning with is to speed up the input process in the Chinese kanji input process described later.

Hereinafter, a method of inputting Chinese, which can extract 27 kinds of head features as described above, using a dialing keypad or a computer keyboard, will be described.

The Chinese kanji input method according to the present invention is proposed by the system after inputting the initial letter of the English alphabet given to each Chinese character and the corresponding identification factor of the two-head feature extracted by the present invention according to the Chinese Pinyin notation method. Selected Chinese characters are selected from among the corresponding Chinese characters. In this case, one or two identification factors representing the two features are input according to the number of the features of the two features that can be extracted from the Chinese characters that require input.

Meanwhile, as shown in FIG. 3, the Chinese Kanji input device capable of performing the Chinese Kanji input method may be implemented by a key input unit 10, a controller 20, a memory 30, a display unit 40, and the like. .

The key input unit 10 is implemented as a user input means of an electronic device such as a dialing keypad of a mobile communication terminal or a keyboard of a computer, and generates corresponding key data when the user presses a predetermined key and outputs the corresponding key data to the control unit 20. Allow numbers and letters to be entered.

The memory 30 stores a database of 3,500 commercial Chinese characters established in China, along with two-headed feature information and Chinese Pinyin information for each Chinese character.

The controller 20 searches the database of the memory 30 according to the user's input selection through the key input unit 10, reads the corresponding Chinese characters, and outputs them through the display unit 40. Among the Chinese characters, the user selects the last selected Chinese character as the input Chinese character by the user through the key input unit 10 and outputs the same through the display unit 40.

Figure 4 shows an example of assigning an identification factor to the dialing keypad using the two-headed feature classification according to the present invention. In determining a button for allocating identification factors in the drawing, it is preferable to consider the frequency of use of the identification factors.

Looking at the dialing keypad illustrated in Figure 4, the numeric keypad of the dialing keypad is assigned with the identification factor and the English letters of the two features.

The numeric keys 1 are assigned to the two-character feature "Su, Ya" and the English letters "B, C, A", and the two are assigned to the two-character feature "Texture, Frozen, Mountain" and the English letters "D, F, E". "Gang, Mon, Geun" and the English letters "G, H, I" are assigned to the two characters "Gye, Ten, Min" and the English letters "J, K", and the two features "Ta, Wang". , "" And "L, M", and "4," "," "," "," "," 6 "," "," "", "6," Q, R ", and" 8, white "and the letter" S, T, U "are assigned to 8, the two features" cloth, arm "and the letter" W, X, V "are assigned to 9, The zeros are assigned "porridge, force, radish" and the letters "Y, Z". In addition, a special symbol "◎" is assigned to the numeric key 1 together with the head type characteristic identification factor, which is adopted as a means for preventing an input error in the Chinese input procedure according to the present invention. I will mention it again.

In the dialing keypad according to the present invention as described above, when a telephone number is input for a call, the number is inputted by dialing a key designated with the corresponding number in the same manner as the method of using the numeric input key of other devices.

In case of inputting Chinese kanji or English character, operate the separate function key to switch from call mode to kanji input mode or English input mode, and then use the corresponding keys to input characters.

The method of inputting an English letter is the same as the method of inputting an English letter on a conventional dialing keypad. For example, in the English input mode, press the numeric key 1 once to display the first letter “B”, press 1 twice in succession to display “C”, and press 1 consecutively for “A”. "Is displayed, and press 1 four times in succession to display" B "again.

In other words, press and hold 1 to select "B", "C", "A", "B", "C", "A". Appears sequentially on the display, and when the desired alphabet appears, the next alphabet is entered, a separate input key is pressed, or if a certain time elapses, the currently selected alphabet is input to the mobile terminal.

On the other hand, after entering the Chinese character input mode by operating a separate function key, the Chinese kanji inputs a combination of the alphabet assigned to each numeric key and two type feature identification factor. Here, the user inputs an alphabetic character or an identification factor assigned to each numeric key in the same manner as the alphabetic character input procedure through the English input mode, and the system automatically discriminates the Chinese character input signal into either an alphabetic input signal or an identification factor input signal. To receive the input.

For example, if you press the numeric key 2 once in Chinese character input mode, the first English letter "D" or the first two features "grain" are displayed on the display, and if you press 2 consecutively, "F" or "un" Is displayed, pressing 2 three times in succession displays "E" or "car", and pressing two consecutive times displays "D" or "grain".

In other words, press and hold 2 to select “D”, “F”, “E”, “D”, “F”, “E”…. Or "grain", "un", "tea", "grain", "un", "tea" ... Appears sequentially on the display, and when the desired alphabetic or two-character feature appears, the next character is entered, a separate input key is pressed, or when a certain time elapses, the currently selected alphabet or two-character feature is input to the mobile communication terminal.

In order to help understand the process of inputting Chinese kanji, which is the technical gist of the present invention, an actual input example of several kanji is described.

<Single Two-character Characteristic Chinese Character: Star (星)>

The star is the first alphabet of Chinese Pinyin, "X", and the two features "sphere" can be extracted from the upper part.

Step 11-After the user enters the Chinese input mode by operating a function key of the key input unit, press the numeric key 9 two times in succession. In this case, in recognizing the key data generated by the key input unit, the controller automatically recognizes the first key data for inputting the Chinese character as the Chinese Pinyin input signal. Herein, since "X" is assigned as the second alphabet of the numeric keys 9, the Chinese pinyin "X" is input to the mobile communication terminal. Preferably, "X" is displayed on the display unit while the Chinese pinyin "X" is input.

Step 12-The user presses the numeric key 8 of the key input once. At this time, the controller automatically recognizes the second key data for inputting the Chinese character as the preceding two-head feature input signal in recognizing the key data generated by the key input unit. Here, since the phrase "sphere" is assigned as the first two-character feature identification factor of the numeric key 8, the two-character feature "sphere" is input to the mobile communication terminal.

Then, the control unit searches the database stored in the memory and extracts the Chinese characters having the first alphabet of Chinese Pinyin "X" and the two features "nine", and when the extraction of the Chinese characters is completed, the upper portion of the display unit as shown in FIG. The identification factor of the input two-character feature "phrase" is displayed, and at the bottom, the extracted Chinese characters are displayed together with the selection numbers from 1 to 6 times.

Here, some Chinese characters with the first alphabet of Chinese Pinyin and "X" and the two-character "gu" have a single two-character, such as "Sung (Star)" that you want to input. Also included are plural Chinese characters with more features. Therefore, the controller extracts and displays only the Chinese characters having the first alphabet of Pinyin Pinyin as "X" and having the two-headed feature "nine" as a single two-headed feature.

Step 13-The user presses numeric key 3 on the key input once. At this time, the controller recognizes one of the Chinese character selection signal and the second two-characteristic input signal in recognizing the key data generated by the key input unit. By the way, "strong" is assigned as the first two-shape feature of the numeric key 3, but according to the two-shape feature extraction method of the present invention, there is no Chinese character in which the identification factor "strong" is extracted as the second two-shape feature among 3,500 commercial characters. Therefore, the control unit recognizes the key data generated by the key input unit as the Chinese character selection signal, and the Chinese character “星” corresponding to the selected number is input to the mobile communication terminal, and the Chinese currently input on the upper side of the display unit as shown in FIG. 5B. The Chinese character "星" is displayed.

Meanwhile, in the step 12, when the first alphabet of Chinese Pinyin alphabet is "X" and the Chinese characters with "two" features are displayed on the lower side of the display part, the Chinese characters are given priority according to their frequency of use, and the Chinese characters with high frequency of use are given. If the kanji exceeds 6, the arrow symbol "▶" is displayed on the display as shown in Figure 4a, and when the user selects the next screen by operating the promised key, the next highest frequency of use is shown. Chinese characters are displayed with a selection number from 1 to 6 times.

In addition, if the Chinese character that the user wants to input in step 13 is not "星", the user will press once any number key other than numeric key 3 of the key input unit or press any number key two or more times.

When the numeric key 1 is pressed once in step 13, the control unit automatically recognizes the key data of the key input unit as the Chinese character selection signal. That is, the special symbol "◎" assigned to the numeric key 1 is a mark for notifying the user that an input error is prevented by not having a corresponding head type feature when the numeric key 1 is selected once.

In step 13, when any one of the numeric keys 2, 4, 5, and 6 is pressed once, according to the two-headed feature extraction method of the present invention, the identification factor "coherence, system, Since there are no Chinese characters extracted with the following two features, the controller recognizes the corresponding key data of the key input unit as the Chinese character selection signal.

According to an embodiment, the display unit displays six kanji characters in step 13 according to an embodiment of the present invention. By minimizing the number of times the user requests the display of the next kanji characters by manipulating a promised key corresponding to the arrow symbol "▶", It is to improve the overall input speed of Chinese characters.

Therefore, according to another embodiment, if only five Chinese characters are displayed on the display unit, the input error prevention function corresponding to the special symbol "?" Assigned to the numeric key 1 may not be adopted. Of course, in this case, the two-shaped features "grain, steel, system, rudder, four," assigned to the numeric keys 2 to 6 in FIG. 4 should be assigned to the two-shaped features that can be input through the numeric keys 1 to 5, respectively.

In step 13, when the user presses any one of the numeric keys 7, 8, and 9 one time or presses any number key two or more times, the head feature assigned to the corresponding numeric key is input. It will be easily understood with reference to the input example of the plurality of head features kanji to be described.

<Multiple two-character feature Chinese characters: (New)

(Shin) is the first alphabet of Chinese Pinyin, "X", and the two separate features "cheon" and "word" are extracted from the left and right.

Step 21-After the user enters the Chinese input mode by operating a function key of the key input unit, press the numeric key 9 two times in succession. In this case, in recognizing the key data generated by the key input unit, the controller automatically recognizes the first key data for inputting the Chinese character as the Chinese Pinyin input signal. Herein, since "X" is assigned as the second alphabet of the numeric keys 9, the Chinese pinyin "X" is input to the mobile communication terminal. Preferably, "X" is displayed on the display unit while the Chinese pinyin "X" is input.

Step 22-The user presses numeric key 9 on the key input once. At this time, the control unit recognizes the key data generated by the key input unit and automatically recognizes the second key data of the Chinese character as the preceding two feature input signals. Therefore, the first two-type feature "cloth" assigned to the numeric key 9 is input to the mobile communication terminal.

Here, since the Chinese pinyin "X" and the two-type feature "cheon" is assigned to the same numeric key, the first key data and the second key data must be separately input for continuous input. The signal separation between the two key data can be used as in the conventional character input method, or a separate signal division function can be used.

Then, the control unit searches the database stored in the memory and extracts the Chinese characters with the first alphabet of "Chinese Pinyin" "X" and the two type features "thousand". The identification factor of "cloth" is displayed, and at the bottom, the extracted Chinese characters are displayed with the selection numbers from 1 to 6 times.

Of course, the Chinese characters currently displayed through the display unit are Chinese characters with a single head feature "thousand". (Shin) is not included, but this phenomenon occurs because the input procedure to date is the same as the input procedure of the single head feature Chinese character described above.

Step 23-The user presses numeric key 2 twice on the key input unit. At this time, the control unit can easily infer that the recognition of the key data generated by the key input unit to any one of the Chinese character selection signal and the following two-head feature input signal. By the way, the Chinese character selection signal that can be input by pressing the numeric key 2 twice is "22" or only 6 Chinese characters are outputted through the display unit according to the present invention, so that the control unit inputs the corresponding key data of the key input unit in the trailing two-head feature. It is recognized as a signal. Thus, the two-shaped feature "un" second assigned to the numeric key 2 is input to the mobile communication terminal.

Then, the controller searches the database stored in the memory and extracts the Chinese characters having the first alphabetic character "X" and the leading two-character "thousand" and the trailing two-character "union". On the upper side, identification factors of the two types of features "cheon" and "un" entered so far are displayed, and on the lower side, the extracted Chinese characters are displayed with the selection numbers from 1 to 6 times.

Step 24-The user checks the Chinese characters outputted on the lower side of the display unit, Recognizes the selection number corresponding to the (new), and presses the corresponding number key once from the number keys 1 to 6 of the key input unit. At this time, the control unit automatically recognizes the Chinese character selection signal in recognizing the key data generated from the key input unit. "Is entered and currently entered Chinese characters at the top of the display" Is displayed.

Here, even if the control unit does not automatically recognize the key data generated by the key input unit as the Chinese character selection signal, as described above in the input procedure of the single head feature Chinese character, the first key is assigned to the numeric keys 2, 3, 4, 5 and 6. Since the two-shaped features "grain, steel, system, other, four" are identification factors extracted only by the preceding two-shaped features, the control unit has no choice but to recognize the corresponding key data of the key input unit as the Chinese character selection signal.

In fact, among the 3,500 common Chinese characters, the Chinese character classified as "Pinyin" in Chinese is 210 characters. Of these, the Chinese character for which the leading head character "Cheon" is extracted is 15 characters. (Shin) is unique. Therefore, in step 24, the user presses the numeric key 1 of the You will enter (New).

On the other hand, when a plurality of the corresponding Chinese characters are displayed at the lower side of the display unit in step 23, priority is given based on the frequency of use and sequentially displayed from the Chinese characters with the highest frequency of use. The arrow symbol "▶" is displayed on the screen. When the user selects the next screen by operating the promised key, the next most frequently used Chinese characters are displayed with the selection number from 1 to 6 times. If this is the case, the user performs step 24 while looking at the next most frequently used Chinese characters 1 to 6 times.

Above As in the example of (Shin), if you sequentially input the Chinese Pinyin and the leading and trailing head features, you can enter plural head features. (G) may be implemented to be input in the same procedure as the input example of a single head-shaped feature kanji or to be input in the same procedure as the input example of a plural head-feature feature kanji.

According to the two-headed feature extraction method described above (G) is a kanji of general form among plural two-headed kanji characters, which corresponds to kanji in which two independent features appear at the upper and left sides. In other words In (g), the feature of the two-headed feature "sa" appears in plural, and both two-headed features "sa" shall be extracted.

When inputting, enter the Chinese input mode by operating the function key on the key input unit, and press the numeric key 8 once to input the Chinese Pinyin "S" into the mobile communication terminal, and press the numeric key 6 on the key input unit once. The preceding head feature "sa" is input to the mobile communication terminal, and when the numeric key 6 of the key input unit is pressed once, the following head feature "sa" is input to the mobile communication terminal. The problem here is that when the numeric key 6 is input for the input of the trailing head feature, the key data may be a selection signal of a single head feature kanji or a trailing head feature input signal. However, since the first alphabet of Chinese Pinyin alphabet is "S" and the single head feature Chinese character with the head feature "four" is not included among the 3,500 commercial characters established in China, the display part does not display any Chinese characters when entering the following head feature. Thus, when the numeric key 6 is pressed once to input the trailing head feature, the corresponding key data is input as the trailing head feature input signal.

here, Even if (G) is classified as a single double-headed Chinese character, the first alphabet of Chinese Pinyin is "S" and a Chinese-headed Chinese character with two-headed "sa" Because (G) is the only one, the number of key operations for entering Chinese characters is reduced, which enables faster Chinese character input.

According to the present invention, among the 3,500 commercially available Chinese characters, a single head feature Chinese character is about 890 characters, and a plurality of head character Chinese characters are represented by about 2610 characters, and about 840 characters of a single head character feature Chinese character can be input through one Chinese character output screen. In addition, about 1560 characters of the plurality of two-character characters can be input through a single Chinese character output screen. In other words, according to the two-type feature input method according to the present invention, about 2,400 characters (68%) among commercially available 3,500 characters are included in priority 1 to 6 based on the frequency of use, and about 1,100 characters (32%) are based on the frequency of use. It is included in one of the priorities 7 to 12.

In addition, when inputting the first alphabet of the Chinese Pinyin and the leading and trailing two features, about 65% is extracted as the only Chinese character.In this case, the user checks the Chinese characters outputted on the display unit and selects the Chinese characters through the key input unit. It is preferable to omit the procedure of inputting. That is, the control unit automatically receives the extracted Chinese characters based on the Chinese Pinyin and the two-type feature information input by the user, and automatically receives the extracted Chinese characters, and the user performs the procedure of inputting the next Chinese character. Of course, this automatic input can also be applied to single head-shape character Chinese characters.

In addition, the Chinese character input device of the present invention is a buzzer or selectively equalized to transmit a beep sound by distinguishing between the case that the corresponding Chinese characters are automatically input only by input of the Chinese Pinyin and two-type features and the user should input the Chinese character selection signal It may also include flashing lights. If the flashing light is adopted, the flashing light should be installed at an appropriate position of the key input unit and controlled through the control unit. When the Chinese character selection signal is input without automatic input, a beep sound may be generated or a blinking light may be turned on to improve identification by the user.

The alphanumeric alphabet assigned to each numeric key can be changed mutually, and the two-shape feature can also change mutual position under the condition of assigning "grain, steel, system, rudder, four," to numeric keys 1 to 6. It is possible.

However, it is preferable to assign the two-character feature and the English alphabet to a location where the number of key signals is higher as the frequency of use is high, and to a location where a number of key signals is to be used when the frequency of use is low.

In the dialing keypad of FIG. 4, the alphabetic alphabet is first assigned two or three alphabetical letters to ten numeric keys 1 to 0 in alphabetical order, and then I is not used as the first letter of the Chinese pinyin among the assigned English letters. This is an example of assigning 6 alphabets of A, E, and O, V, U, and very low frequency to 3 key signals regardless of order (39 Chinese and Pinyin beginning with A, E, and O alphabets. 21, only 6). The method for assigning alphabetic characters is intended to shorten the character input speed by enabling the input of the first Chinese character Pinyin Pinyin of the most Chinese characters less than two times the number of key signals.

6 shows another example in which an identification factor is assigned to a dialing keypad using the two-headed feature classification method according to the present invention. Differences are found in the numeric keys 1, 5, 7, 0 as compared with the example of the identification factor assignment of the dialing keypad shown in FIG.

Assign the special symbol "◎" and the two-shaped "Su / Ya, Sun / Tee" to the numeric key 1, the two-type "Ta, the King" to 5, and the two-character "Tea, Neck" to , 0 is assigned "porridge, power / nothing".

The two-shape feature assigned to the numeric keys 5 and 7 is only a state in which one of the two-shape features is removed when compared to the dialing keypad of FIG. 4, and thus the description of the two-shape feature input procedure using the same will be omitted.

Numeric Key 1 is assigned the number two / female as the second two-character feature. When the user attempts to input the two-character feature by pressing the numeric key 1 twice, the two-character feature “Number” and the two-character feature “Ya” are entered together. It means. When entering 3,500 characters, the two-character feature "number" and two-character feature "ya" have a low frequency of use and the number of the corresponding Chinese characters is small. This is because it is easy to find the desired kanji even when the kanji with the two characters and the kanji with the two features "ya" are displayed together. This simultaneous input function is equally applicable to "one / two" assigned to the numeric key 1 as the third two-character feature and "force / nothing" assigned to the second two-character feature at zero.

Compared with the dialing keypad of FIG. 6 as described above, the dialing keypad of FIG. 4 is assigned to the third two-characteristics in the numeric keys 5, 7, 0, respectively, but in FIG. It can be seen that only the second two features are assigned. As a result, the number of key manipulations for Chinese character input is reduced in the dialing keypad of FIG. 6 compared to the dialing keypad of FIG.

On the other hand, in the dialing keypad of Figs. 4 and 6, an input error prevention function using a special symbol "◎" is adopted, and as described above, when only five Chinese characters are displayed on the display unit, the special symbol "◎" is supported. It is not necessary to adopt an input error protection function, and as another embodiment, by adding one more identification factor that is used only in the plural-headed feature Chinese characters, such as the head-shaped feature "grain, steel, system, other, four," the special symbol "◎". Is assigned to the same position as the existing position, it is also not necessary to adopt the input error protection function corresponding to the special symbol "◎".

For example, It is a case of adopting a total of 28 head features by adding as a new head feature identification factor and assigning the first head feature of the numeric key 1 on the dialing keypad of FIG. 4 or 6. Similar to the two-shaped feature "grain, river, system, other, four", the input corresponding to the special symbol "◎" because there is no Chinese character extracted only from plural-headed feature Chinese characters and the identification factor is extracted as a trailing two-feature feature among 3,500 commercial characters. Even if the error prevention function is not adopted, no error occurs when inputting the Chinese character selection signal.

In the Chinese kanji input method described so far, when the user extracts and inputs the Chinese Pinyin and two features of the Chinese character that he / she wants to input, the user can enter the corresponding Chinese characters. In this case, the process of inputting the desired Chinese character will be described.

If you know only one of the information between Hanyin Pinyin and the two types, use a specific key as an input key for unknown information.If you don't know Hanyin Pinyin information, after pressing a certain key (* or #, etc.) If you do not know the information of the two-type feature to input the first alphabet pinyin pinyin information after pressing the specific key to select the Chinese characters to be input from the Chinese characters displayed on the display to enter.

For example, when you want to input a single star-shaped Chinese character, the star is the first alphabet of Chinese Pinyin, "X", and you can extract the two-shaped feature "gu" from the upper part. If you do not know Pinyin, press the specific key (* or #, etc.) instead of the first letter "X" in Chinese Pinyin and enter the two-character "Phrase" in succession. After entering the letter "X", press the specific key (such as * or #) instead of the two-character "sphere".

As described above, in order to help understand the process of alternatively inputting only one of the Chinese Pinyin and the two types of features, the process of inputting the surname (星), which is a single two-character feature, will be described in more detail.

<If you do not know Chinese Pinyin information>

Step 31-The user presses a specific key (* or #, etc.) after entering the Chinese input mode by operating a function key of the key input unit. At this time, the control unit recognizes the key data generated by the key input unit and automatically recognizes the first key data for Chinese character input as the Chinese Pinyin input signal unconditionally. Recognize it as a signal.

Step 32-The user presses the numeric key 8 of the key input unit once. At this time, the controller automatically recognizes the second key data for inputting the Chinese character as the preceding two-head feature input signal in recognizing the key data generated by the key input unit. Here, since "sphere" is assigned as the first two-character feature identification factor of the numeric key 8, the two-character feature "sphere" is input to the mobile communication terminal.

Then, the control unit searches the database stored in the memory and extracts the Chinese characters having the phrase “nine”, regardless of the first alphabet of Chinese Pinyin. When the extraction of the Chinese characters is completed, the controller displays the currently input two character features “. The identification factor of "Phrase" is displayed, and at the bottom, the extracted Chinese characters are displayed with the selection numbers from 1 to 6 times.

Here, some Chinese characters having the two-character "gu" have a single Chinese character, such as "Sung", which are currently being input. In addition to the two-character "gu", there are a plurality of Chinese character characters having a further two-character. However, the control unit extracts only the Chinese characters having the two-headed feature " sphere " as a single head-shaped feature and displays it on the display unit.

Subsequent Chinese kanji input process is the same in principle and procedure when compared with the above-described step 13, so a detailed description thereof will be omitted.

On the other hand, in the case of a plural head feature kanji that is not a single head feature kanji, as described above, after inputting the preceding head feature, the trailing head feature is input. In this case, when the trailing head feature is normally input, the controller performs the head feature “old”. And display a plurality of head feature Chinese characters having both a specific trailing head feature currently being input, and when a special key is input again as a trailing head feature input signal, the controller returns the preceding head feature regardless of the Chinese pinyin and trailing head feature. A plurality of head-shaped feature Chinese characters having a "are extracted and displayed on the display unit.

<If you do not know the head feature information>

Step 41-The user enters the Chinese input mode by operating a function key of the key input unit and then presses the numeric key 9 twice in succession. In this case, in recognizing the key data generated by the key input unit, the controller automatically recognizes the first key data for inputting the Chinese character as the Chinese Pinyin input signal. Herein, since "X" is assigned as the second alphabet of the numeric keys 9, the Chinese pinyin "X" is input to the mobile communication terminal. Preferably, "X" is displayed on the display unit while the Chinese pinyin "X" is input.

Step 42-The user presses a specific key (such as * or #). At this time, the control unit recognizes the key data generated from the key input unit, and automatically recognizes the second key data for inputting the Chinese character as the preceding two-type feature input signal. However, since the two-type feature is not assigned to the specific key currently input, the unknown two type Recognize it as a feature signal.

Then, the controller searches the database stored in the memory and extracts the Chinese characters whose first alphabet is "X" regardless of the two-type feature. When extraction of the Chinese characters is completed, the Chinese characters extracted at the lower side of the display unit once Mark up to 6 times with the selection number.

Here, among the Chinese characters having the Chinese Pinyin "X", some Chinese characters have a single head feature, such as "Star", which are currently being input, and a plurality of head features include Chinese characters, but the control unit only has Chinese characters having a single head feature. Is extracted and displayed on the display unit.

Subsequent Chinese kanji input process and process is the same principle and procedure when compared with the above step 13 will be omitted detailed description.

On the other hand, in the case of a plural head feature kanji that is not a single head feature kanji, after entering a special key as a preceding head feature, the trailing head feature is input. A plurality of head feature Chinese characters having a specific trailing head feature currently input are displayed on the display unit, and when a special key is input again as a trailing head feature input signal, the control unit has a plurality of Chinese pinyin "X" regardless of the preceding and trailing head feature. Extract two Chinese characters and mark them on the display.

Figure 7 shows an example of assigning an identification factor to a computer keyboard using the two-headed feature classification according to the present invention. Since the Chinese kanji input method using the computer keyboard of FIG. 7 has the same principle as the kanji input method using the dialing keypad described above, only the differences when applied to the computer keyboard will be described below.

When entering an English letter, as in a normal computer keyboard, pressing a specific key in the English input mode, the English letter assigned to the key is input.In the Chinese character input mode, as in the dialing keypad described above, the computer is set according to the location of the key data. It automatically recognizes either Chinese Pinyin input signal or two type characteristic input signal and receives corresponding information.

The "day / day" assigned to Q, the "day / night" assigned to W, and the "force / nothing" assigned to X are simultaneous input functions as described on the dialing keypad, Y, U, I, O, P Like the numeric keys 2 to 6 of the dialing keypad, is used for inputting the Chinese character selection signal, and in the case of inputting Chinese characters up to six characters on the display unit (monitor) during the Chinese character input process, Z is the Chinese character selection of the numeric key 1 on the dialing keypad. Has the function. Of course, the Chinese character selection function through Y, U, I, O, P, and Z can be given to a ten key provided separately on a computer keyboard.

In addition, the present invention discloses a method of using a predetermined key as an input key for unknown information in order to input a desired Chinese character in the case of not knowing any one of the Chinese Pinyin and the two type features in the aforementioned dialing keypad. The same applies to the computer keyboard of FIG. 7, and a key for which no two-type feature is assigned is used as an input key for unknown information. In the computer keyboard of FIG. 7, V is used as an input key for unknown information, and in the drawing, # is written for identification.

Meanwhile, as described above, the computer may be implemented to automatically recognize either the Chinese Pinyin input signal or the two-type characteristic input signal according to the position of the key data in the Chinese character input mode. Since both types of keys are input simultaneously, there is no difficulty due to the input. If only one key is input independently in the Chinese character input mode, the two types of features assigned to the key are input, and a separate function key such as a shift key. If is input at the same time may be implemented so that the English alphabet assigned to the key is input.

In the above description, but limited to a few embodiments of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art.

For example, in the above-described embodiment, the Korean pinyin pinyin may be used. Alternatively, the Chinese pinyin may be replaced with the integrated pinyin, and another pinyin system may be used. Using the alphabet is also an example only.

Such modified embodiments should be included in the technical spirit described in the claims of the present invention.

As described above, the present invention improves the character input speed by shortening the input stroke compared with other conventional Chinese input methods.

Conventional Chinese Pinyin input method is able to input exactly knowing all Chinese Pinyin spelling, and the pentagonal input method requires a considerable knowledge of the Chinese copy, while the Chinese input method of the present invention if only the first English letter of Chinese Pinyin Even if you do not know the sound or the number of Chinese characters you want to input, you can easily extract the two features.

In addition, it is possible to unify the way of inputting Chinese characters into all electronic devices, such as the dialing keypad and computer keyboard, as described in the detailed description, thereby eliminating problems such as input error or mastery delay caused by using different methods. It works.
