Description

Method for entering Chinese characters

technical field

The invention relates to a character input method, in particular to a method for inputting Chinese characters.

Background technique

Chinese characters, as a kind of pictographic characters, are significantly different from other kinds of phonetic characters in the world. It has thousands of different characters, making it difficult for users to input desired Chinese characters into computers or other in electronic equipment. Due to the huge quantity of Chinese characters, there is actually no keyboard corresponding to various Chinese characters. Therefore, how to input Chinese characters into various devices accurately and efficiently has become more and more important.

Since the number of Chinese pinyin is far less than the number of Chinese characters, users generally use a smaller keyboard with specific English letters, such as an English QWERTY keyboard, to input Chinese pinyin, and then convert the Chinese pinyin into Chinese characters to complete the Chinese characters. enter.

However, so far, the devices that can easily input Chinese characters are also mainly limited to English QWERTY keyboards such as those used for personal computers, wherein on this type of keyboard, each key only corresponds to an English letter or symbol respectively. . For Chinese character input, one Chinese pinyin letter corresponds to one English letter. When using this keyboard to input Chinese characters, the user can conveniently input the Chinese Pinyin letters by directly pressing the keys on the keyboard corresponding to the Chinese Pinyin letters according to the Chinese Pinyin corresponding to the single Chinese character to be input. Since this keyboard provides a unique input button for each Chinese pinyin letter, each input operation of the user can uniquely correspond to a certain Chinese pinyin letter, thereby providing the user with a choice according to the Chinese pinyin. A single Chinese character, the user confirms the input content after selecting.

Although Chinese characters can be conveniently input through the above-mentioned keyboard, for portable devices with few keys, such as mobile phones, various Chinese input methods in the prior art have great limitations.

As everyone knows, with the continuous popularization of mobile phones, ITU-T keyboards have been widely used. The ITU-T keyboard is a standard keyboard, which mainly includes number keys 0-9. These numeric keys can be used to enter phone numbers. Also, some number keys correspond to 26 letters and are used to input these letters. For example, number key 2 represents A, B and C; 3 represents D, E and F; 4 represents G, H and I, 5 represents J, K and L; 6 represents M, N and O; 7 represents P, Q, R and S; 8 for T, U and V; and 9 for W, X, Y and Z.

Therefore, in order to input Chinese Pinyin to the mobile phone, it is very inconvenient to only use the above-mentioned several keys.

Since each key on the keyboard corresponds to multiple English letters, in order to input a desired letter, the user must press a certain key for a certain number of times within a certain period of time. For example, in order to input the pinyin "zhong" through an ITU-T keyboard, the user must press the number key 9 four times to input "z", press the number key 4 twice to input "h", and so on. To input the entire pinyin "zhong", press the key 12 times.

Later, a kind of intelligent input method called "intelligent typing" was developed. The idea of "smart typing" is to automatically filter out some impossible letters, thereby greatly reducing the number of key presses. Still taking inputting the pinyin "zhong" as an example, input "z" in the same way as above. However, in order to input "h", the user only needs to press the key number once, because the letter "g" and the letter "z" before the letter "h" are not a legal pinyin combination. In the "smart typing" method, the user only needs to press 9 keys to input the pinyin "zhong".

Currently, for mobile phones or PDAs with ITU-T keyboards, the most commonly used Chinese character input methods are called T9 and E-Zi. They are called "single typing" input methods. In the "single input" method, the user does not need to care about the order of letters on each key, and only needs to press a certain key once in order to input all pinyin. The mobile phone or PDA will list all legal pinyin combinations for the user to choose. Also take the input pinyin "zhong" as an example, the user only needs to press the number keys 9-4-6-6-4 in sequence, and the mobile phone will list two candidate pinyin "zhong" and "xiong" for the user to choose. For the "single typing" input method, the number of times the user presses the key is usually equal to the length of the pinyin, but an additional selection step is required. Therefore, it is also necessary to press the key additionally.

Therefore, there is a need in the art to provide a new Chinese character input method, so that when the user uses an input device such as an ITU-T keyboard to input Chinese characters, the number of keystrokes required to input pinyin can be reduced.

Detailed ways

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components.

Figure 1 shows a typical mobile phone. The mobile phone 100 includes a keypad 101, a display 102, an antenna 103, a memory (not shown), and the like.

As shown in FIG. 1 , the keyboard 101 is realized by a keyboard with 10 numeric keys, which has numeric keys 0-9 and some other function keys, such as an answer key, a cancel key, and a menu key. The display 102 is used for displaying, for example, phone numbers, short messages, and input text.

The number keys 2-9 can be used to input English letters or Chinese pinyin letters, for example, the number keys 3 can be used to input English letters or Chinese pinyin letters D, E and F. There are different ways to enter a desired English letter.

One way is to press the number key associated with the English letter, and the mobile phone can automatically identify the letter to be input according to the previously input English letter. For example, by pressing the number key 6, the mobile phone can determine one of M, N and O according to the previously input text.

Another way is to press the same key once or several times to determine the English letter associated with the key. For example, to input the letter N, the user presses the number key 6 twice; to input the letter O, the user presses the number key 6 three times; to input the letter P, the user presses the number key 7 once.

Of course, there are other different input methods of English letters or Chinese pinyin. No longer stated here one by one, the user can input the Chinese pinyin of Chinese characters in the above-mentioned different ways, and complete the input of Chinese characters by retrieving the single Chinese character corresponding to the Chinese pinyin from the memory of the mobile phone.

Fig. 2 shows an arrangement of a display and a numeric keypad of a mobile phone according to the present invention.

Referring to FIG. 2 , the display 102 according to the present invention includes an upper portion 210 for displaying input text and a lower portion 202 for corresponding to each number key of the keyboard 101 . Wherein, the upper part 210 is used to display the input text. The lower part 202 is a block divided into nine areas in the form of 3 rows x 3 columns, and each area corresponds to the number keys 1-9 on the keyboard 101 respectively. Each area is used to display different pinyin letters or characters, such as initials and finals. Through the simple mapping relationship, the user can select the content of the corresponding area in the lower part 202 by pressing the number keys on the keyboard 101 , and display the final selection result on the upper part 201 of the display 102 . Since the specific mapping relationship is irrelevant to the present invention, no further description is given here.

Fig. 3 is a schematic diagram showing the corresponding relationship between the lower part of the display and the initials and finals of Pinyin according to the present invention.

Referring to FIG. 3, the lower part 202 of the display according to the present invention is divided into 9 areas, which are indicated by numerals 1-9 respectively. First, all the initial consonants of the pinyin are divided into 8 groups, which are displayed in the 8 regions of the lower part 202 . As shown in Figure 3, area 1 includes initial consonants b, p, m, area 2 includes initial consonants d, t, n, area 3 includes initial consonants g, k, h, area 4 includes initial consonants j, q, x, area 5 includes initial consonants z, c, s, area 6 includes initial consonants zh, ch, sh, area 7 includes initial consonants y, w, r, area 8 includes initial consonants f, l. And make region 9 include finals a, o, e.

The user can input pinyin with initial consonants by pressing number keys 1-8, and can input pinyin without birth mother by pressing number key 9.

Still referring to FIG. 3 , after the user inputs an initial consonant by pressing the number keys 1-8, the nine areas of the lower part 202 of the display include different final consonants respectively. As shown in Figure 3, area 1 includes finals a, an, ang, area 2 includes finals ia, ian, iang, ai, area 3 includes finals ua, uan, uang, area 4 includes finals e, en, eng, area 5 Includes the finals i, in, ing, region 6 includes the finals ui, ue, un, iu, region 7 includes the finals o, ou, ong, ao, region 8 includes the finals iao, iong, ie, ei, and region 9 includes the finals u , uo, ü, uai.

After the user inputs the pinyin without consonants by pressing the number key 9, the nine areas of the lower part 202 of the display contain different final consonants respectively. As shown in Figure 3, area 1 includes the final a, area 2 includes the final e, area 3 includes the final ai, area 4 includes the final an, area 5 includes the final en, area 6 includes the final ao, area 7 includes the final ou, and area 8 Including the final er. Pressing the number key 9 again, two of the nine areas in the lower portion 202 of the display include different finals. Region 1 includes the final ang, region 2 includes the final ei and region 3 includes the final o.

The pinyin input method according to the present invention will be described below through specific examples.

In this embodiment, the description is made by taking the input of Chinese pinyin with initial consonants as an example, for example, taking the input of the Chinese character "中" as an example.

With reference to Fig. 4, at first select initial consonant. The initial consonant distribution is shown in Figure 4. The initial consonant "zh" of Chinese pinyin is located in area 6, and the user presses the corresponding number key 6 to input "zh".

Then, choose the vowel. After the initial consonant is input, the final vowel is automatically displayed on the screen. As shown in FIG. 5 , the final "ong" is located in area 7, and the user presses the corresponding number key 7 to input "ong".

It should be noted that due to the difference in the number of initial consonants and final consonants in Chinese Pinyin, the number of final consonants is more than the number of initial consonants. Therefore, when inputting initial consonants, the area mapped on each key includes a maximum of three initial consonants. And when inputting finals, the zone mapped on the key that has comprises three finals, and the zone mapped on the key that has comprises four finals. For the key that only includes three finals, by inputting the initials and finals, the combination of two keys can form up to nine pinyins. As for the regions containing four finals, there are a pair of "mutually exclusive finals" in the finals they contain, that is, two finals cannot form a legal pinyin with the same initial. In this way, it can be guaranteed that there are still no more than 9 reasonable pinyin combinations. Table 1 shows mutually exclusive finals for all finals.

Table 1: List of mutually exclusive finals

After input initial consonant " zh " and final consonant " ong " ", all possible phonetic combinations corresponding to the region 6 of input initial consonant and the region 7 of input final consonant are displayed on the lower part 202 of display 102.As shown in Figure 6, because The pinyin "zhong" is located in area 2, and the user presses the number key 2 to complete the pinyin input.

Of course, the user can also reduce the number of candidate Chinese characters by inputting tones (such as using the "*" key or the "0" key).

In addition, if the character to be input is not in the candidate character list, the user can use the up and down keys to turn the page, view more candidate characters, and finally select the Chinese character to be input.

The process of inputting Chinese characters with initial consonants according to the present invention is described above by taking the Chinese character "中" as an example.

In another embodiment of the present invention, the input of Chinese pinyin without initial consonants is taken as an example for description, for example, the input of the Chinese character "An" is taken as an example.

Similarly, with reference to Fig. 4, at first, select no initial consonant area in the initial consonant table. The region without initials corresponds to region 9, denoted by "a, o, e". The user presses the corresponding number key 9 to select the pinyin without initials.

Then, the lower portion 202 of the display 102 lists the silent pinyin, as shown in FIG. 8 . Since there are 11 silent phonetic alphabets, they cannot be displayed on one page. Therefore, the first page only shows 8 more commonly used silent consonants, namely "a, e, ai, an, en, ao, ou, er". The user can press the number button 9 to browse the pinyin on the next page. The second page contains 3 uncommonly used silent consonant pinyin, namely "ang, ei, o", as shown in Figure 9.

In this embodiment, since the final "an" is located in the area 4 of the first page, the user can press the number key 4 to select the final "an".

After completing the final input, all Chinese characters corresponding to the pinyin are displayed on the lower part 202 of the display 102 . As shown in FIG. 10 , the Chinese character "An" is located in area 1. The user presses the number key 1 to complete the Chinese character input.

Similarly, the user can also reduce the number of candidate Chinese characters by inputting tones (such as using the "*" key or the "0" key).

In addition, if the character to be input is not in the candidate character list, the user can use the up and down keys to turn the page, view more candidate characters, and finally select the Chinese character to be input.
