Description

Technical Field

[0001] The present invention relates to the technical field of Chinese character input methods, and specifically to a new type of pure pen-based Chinese character input method and its dedicated keyboard. Background Art

[0002] The Wubi font input method and the pinyin input method are two commonly used Chinese character input methods. The radicals of the Wubi font input method are difficult to remember, the corresponding codes of the radicals are difficult to remember, and the splitting of Chinese characters is difficult; while the pinyin input method has defects such as low recognition accuracy and inability to input characters that cannot be pronounced, which affect the ability of information processing devices such as computers and mobile phones to process Chinese characters. Summary of the Invention

[0003] The purpose of the present invention is to provide a new type of pure pen-based Chinese character input method and its dedicated keyboard to at least to a certain extent solve the above problems existing in the related technologies.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A new type of pure pen-based Chinese character input method, the input method comprising the following steps:

[0006] Step 1, encoding radicals on the key positions of the information processing device, wherein the types of radicals include radical radicals of Chinese characters, whole-character radicals, stroke radicals, and combined radicals. The encoding of radical radicals of Chinese characters is mainly the first letter of the pinyin of the general name of the radical, and the encoding of whole-character radicals is mainly the first letter of the pinyin of the character;

[0007] Step 2, splitting the Chinese character to be input according to the stroke order of the Chinese character by using various radicals, and selecting at most four radicals from the split radicals; and

[0008] Step 3, typing the keys corresponding to the at most four radicals to input the Chinese character.

[0009] Preferably, the stroke radicals and their encodings are as follows:

[0010]

[0011]

[0012] Preferably, the types and encodings of the combined radicals are as follows:

[0013]

[0014] The combined radicals do not include combinations ending with a dot or a stroke, nor combinations containing the stroke fold.

[0015] Preferably, the radical with the pinyin of "you" has the encoding of "U".

[0016] Preferably, the types of root characters further include nearly complete-character root characters and nearly radical root characters. The encoding of the nearly complete-character root characters is the encoding of the complete-character root characters similar to them, and the encoding of the nearly radical root characters is the encoding of the radical root characters similar to them.

[0017] Preferably, the types of root characters further include letter-like root characters. The encoding of the letter-like root characters is the letter. The letter-like root characters include one or more of the following root characters: root characters similar in shape to the letter, root characters with the first stroke similar in shape to the letter, and root characters with the last stroke similar in shape to the letter.

[0018] Preferably, the types of root characters further include frame-shaped root characters. The frame-shaped root characters and their encodings are as follows:

[0019]

[0020] Preferably, in step two, the method of selecting at most four root characters includes:

[0021] When the number of root characters split is four or more, the first, second, third, and last root characters are taken in sequence;

[0022] When the number of root characters split is less than four, all the root characters are taken in sequence, and the stroke root character of the last stroke of the Chinese character is taken as the recognition code;

[0023] When the Chinese character to be input is a root-character, the root character, the stroke root character of the first stroke of the Chinese character, and the stroke root character of the last stroke of the Chinese character are taken in sequence.

[0024] Preferably, in step two, the method of splitting the Chinese character to be input further includes: splitting according to the stroke order of the Chinese character, giving priority to taking large components, looking at single strokes, making multiple components yield to the whole, using the component with a missing part when there is a missing part, yielding to the lower component when both have missing parts, and not yielding for regular characters.

[0025] A special keyboard for the novel pure pen-type Chinese character input method as described above provided by the present invention includes 13 letter keys. The 26 letters are combined in pairs in the order of the alphabet and distributed on the 13 letter keys, and the main bodies of the key positions are neatly arranged.

[0026] A special keyboard for the novel pure pen-type Chinese character input method as described above provided by the present invention includes 14 letter keys. The 14 letter keys are arranged in three rows. From left to right, the letter keys in the first row are QW, ER, TY, UI, OP in sequence; the letter keys in the second row are AS, DF, GH, JK, L in sequence; the letter keys in the third row are ZX, CV, BN, M in sequence.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] Since most of the root characters are common radicals, there is no need to memorize them and one can start using them directly. Moreover, most of the root characters use their first pinyin letters as codes, so that once the root characters are disassembled, their codes can be written immediately, which is simple and straightforward. Also, the concept of combined root characters is introduced, which unifies many root characters that are difficult to understand and remember with a simple rule, and the coding rule is simple. The concept of combined root characters is applied in the process of disassembling characters, making the disassembly of root characters more reasonable and easier to operate. In addition, the disassembly and coding of Chinese characters are completely in accordance with the writing stroke order, which is consistent with the writing habit, facilitating quick learning and improving the input speed. Therefore, this input method has the characteristics of simple rules, direct image, easy to remember, and can effectively improve the ability of information processing devices such as computers and mobile phones to process Chinese characters.

[0038] The present invention will be further described below in conjunction with the drawings and embodiments.

[0039] In this application, "the code of...... root characters is mainly......" means that: the codes of most of the root characters in this type of root characters are...... For example, the code of the whole character root is mainly the first pinyin letter of the character, which means that: the codes of most of the whole character roots are the first pinyin letters of the characters.

[0040] This input method is a new type of pure pen-based Chinese character input method, which is designed with the priority consideration of simple rules, direct image and easy to remember, and the secondary consideration of low rate of homophonic characters.

[0041] This input method includes the following steps:

[0042] Step 1: Encode the radicals on the key positions of the information processing device, wherein the types of radicals include radicals, whole-word radicals, stroke radicals and combined radicals, the radical radicals are encoded as the first pinyin letter of the common name of the radical, and the whole-word radicals are encoded as the first pinyin letter of the word;

[0043] Step 2: using the various radicals, splitting the Chinese characters to be input according to the stroke order of the Chinese characters, and selecting at most four radicals from the split radicals; and

[0044] Step 3: Type the keys corresponding to the maximum four radicals to input the Chinese character.

[0045] Figure 1 The root list is shown in FIG. Figure 1 As shown, the input method uses 26 English letters as codes, and each radical uses one English letter as code. In this way, radicals can be conveniently assigned to letter keys of an information processing device, that is, radicals are encoded in the key positions of the information processing device. The information processing device described in this application includes but is not limited to computers and mobile phones.

[0046] In this input method, most of the root characters are common radicals. In this application, such root characters are collectively referred to as radical root characters. The code of such root characters is the first letter of the pinyin of the common name of the radical. For example:

[0047] 扌, handle side, code is: T;

[0048] 阝 is divided into: left ear side, right ear side, collectively called ear side, the code is: E.

[0049] Some radicals are complete Chinese characters. In this application, such radicals are collectively referred to as whole-character radicals, and such Chinese characters are called radical characters. The encoding of such radicals is the first pinyin letter of the character.

[0050] For example:

[0051] Mouth, the code is: K;

[0052] Ba, the code is: B.

[0053] Some radicals are strokes, and these radicals are collectively referred to as stroke radicals in this application. Stroke radicals are further divided into basic stroke radicals (see attached Figure 2 ), multi-stroke radicals (see attached Figure 3 ).

[0054] The number of stroke radicals is small, so a specific encoding is used. Figure 2As shown in the figure, the basic strokes are: horizontal, vertical, left-falling stroke, right-falling stroke, dot, lift stroke, and fold stroke, and the corresponding codes are: G, H, P, N, D, T, Z. Among them, fold stroke is divided into: L-shaped fold, V-shaped fold, J-shaped fold, and other fold strokes, and the corresponding codes are: L, V, J, Z. Figure 3 As shown, the encoding of multi-stroke radicals composed of multiple strokes of the same type is as follows:

[0055] One horizontal line, two horizontal lines, three horizontal lines, and four horizontal lines are coded as G, F, S, and S.

[0056] One point, two points, three points, four points, the codes are: D, Y, I, S;

[0057] One vertical line, two vertical lines, three vertical lines, four vertical lines, their codes are all: H;

[0058] One stroke, two strokes, three strokes, four strokes, their codes are all: P;

[0059] One fold, two folds, three folds (V-shaped fold), their codes are all: V;

[0060] One fold, two folds, three folds (other folds), their codes are all: Z.

[0061] Figure 1 The radical table shown in the figure also contains a small number of combined radicals, that is, radicals composed of multiple stroke radicals. The six strokes of horizontal, vertical, left, right, dot and right stroke can be combined with each other, and cannot end with a dot or right stroke. The broken stroke cannot be combined. The combined radicals are divided into: single strokes and combined roots of single strokes (see attached Figure 4 ), single-stroke and multi-stroke combination radicals (see attached Figure 5 ), a combination of three horizontal and vertical strokes connected end to end (see attached Figure 6 ).

[0062] like Figure 4 As shown, for the combined radicals of single strokes and single strokes, the encoding method is to use the encoding of the first stroke as the encoding of the combined radical according to the stroke order of Chinese characters. This type of combined radicals must exclude combinations ending with dots or right strokes. For example:

[0063] The first and second strokes of the Chinese character 布 are a combination of horizontal and vertical strokes, coded as G;

[0064] Zhuo, the 1st and 2nd strokes, a combination of vertical and horizontal strokes, coded as H;

[0065] For the 4th and 5th strokes, the left-falling stroke and the right-falling stroke must end with a dot and cannot be combined.

[0066] like Figure 5As shown, for the combined radicals of single strokes and multiple strokes, the encoding method is to use the encoding of multiple strokes as the encoding of the combined radical, and this type of combined radical needs to exclude the combination ending with a dot or a dot. For example:

[0067] Then, for the 2nd, 3rd, and 4th strokes, two horizontal strokes and one left stroke are combined, and the code F of two horizontal strokes is used as the code of the combination;

[0068] The 3rd, 4th and 5th strokes are a combination of one vertical and two horizontal strokes, and the code F of the two horizontal strokes is used as the code of the combination;

[0069] Ping, the 1st, 2nd and 3rd strokes are a horizontal line with two dots, ending with two dots, and cannot be combined;

[0070] The 3rd, 4th and 5th strokes of "Cong" are composed of two strokes and a dot, ending with a dot and cannot be combined.

[0071] like Figure 6 As shown, for the combined radical composed of three horizontal and vertical strokes connected end to end, the encoding method is to use S as the code of the combined radical. For example:

[0072] Convex, the 1st, 2nd and 3rd strokes, the three vertical and horizontal strokes are connected end to end and can be combined. The code is: S.

[0073] Combining radicals also include the following rules:

[0074] 1. The folding stroke cannot be combined with other strokes. For example, the 3rd and 4th strokes, the folding point, cannot be combined;

[0075] 2. The strokes of the Chinese character should be intersecting, connected, and adjacent. Cross-stroke combinations are not allowed. For example, the dot and the last horizontal stroke of the 7th and 8th strokes of the Chinese character "国" (国) are not connected or adjacent, so they cannot be combined.

[0076] 3. Stroke combinations cannot cross other strokes, otherwise they cannot be combined. For example, the character 井 cannot be split into: 1st-3rd strokes (two horizontal strokes and one left stroke), 丨; instead, it should be split into: 二, 3rd-4th strokes (left stroke and vertical stroke combination).

[0077] Figure 1 There are some radicals in the radical table shown, which are close to whole-character radicals or radicals, and they are referred to as near-whole-character radicals and near-radical radicals in this application. The encoding of the near-whole-character radical is mainly the encoding of the whole-character radical close to it, and the encoding of the near-radical radical is mainly the encoding of the radical radical close to it.

[0078] Near-whole-word radicals include the following forms:

[0079] 1. The radical is part of the radical of the whole character. For example, the 1st to 4th strokes of "敖" are the upper half of the character "青". The code of "青" is used as its code, and the code is: Q. The 1st to 5th strokes of "贵" are a little less than the character "虫". The code of "虫" is used as its code, and the code is: C.

[0080] 2. Part of the radical is the radical of the whole character. For example, for "登", the 1st to 5th strokes are a radical, and its left half is "又", so U is used as its code. For "卷", the 1st to 6th strokes are a radical, which is a half-character with an extra stroke, so the half-character code B is used as its code. For "养", the 1st to 7th strokes are a radical, which is a sheep with an extra stroke, so the sheep code Y is used as its code.

[0081] Figure 1 There are also a small number of letter-like radicals in the radical table shown, and the code of the letter-like radical is the letter. The letter-like radicals include the following:

[0082] 1. The radicals and letters are similar in shape. For example:

[0083] Person, the code is: A;

[0084] Teacher (left part), and (1st and 2nd strokes), the code is: B;

[0085] 氵 (written in running script, one dot and one vertical line, very similar to i), the code is: I;

[0086] 丂,考(5th and 6th strokes), the code is: S;

[0087] 乂, the code is: X;

[0088] Ya, sheep, the code is: Y;

[0089] 郏 (stroke 2, 3, 4), written very much like P, coded as: P;

[0090] 刂, find (the 1st and 2nd strokes), the code is: J;

[0091] 纟,母,勿,彑(1st and 2nd strokes), the first stroke is very similar to L, the code is: L;

[0092] The first stroke of "女" (female) looks like a turned V. The first or second stroke of "戈" (style (5th or 6th stroke)) looks very much like a V. The code is: V.

[0093] 2. The first stroke of a radical is similar to a letter in shape, or the last stroke of a radical is similar to a letter in shape. For example:

[0094] Mother, 纟, the first stroke is: 折 (L折), the code is: L;

[0095] 刂, the last stroke is: 折(J折), the code is: J.

[0096] The types of root characters also include frame-shaped root characters, see the appendix Figure 7 . Frame-shaped root characters mainly use pictographic letters as their codes. Specifically, as Figure 7 shown, frame-shaped root characters include upper frame, lower frame, left frame, right frame, and E-shaped frame. Among them, the code for the upper frame is U, and Chinese characters containing the upper frame are such as: xiong. The code for the lower frame is n, and Chinese characters containing the lower frame are such as: tong, zhou, guo. The running script shape of the left frame is like Z, and the code is Z. Chinese characters containing the left frame are such as: yi. The code for the right frame is C, and Chinese characters containing the right frame are such as: hui. The code for the E-shaped frame (including the reverse E frame) is E, and Chinese characters containing the E frame (or reverse E frame) are such as: nue, su, gen. Frame-shaped root characters also include: root characters starting with the upper frame, such as chao; root characters starting with the lower frame, such as the first to third strokes of dan and the second to fourth strokes of li; root characters starting with the left frame, such as yi, ji, si; root characters starting with the reverse E-shaped frame, such as gen; their codes are the same as the corresponding frame-shaped root characters, that is, U, N, Z, C, E respectively.

[0097] In addition, there are some root characters that are not complete Chinese characters and do not have a common radical name, so the code of the first stroke or the last stroke of the root character is used as the code of the root character. For example:

[0098] The first strokes of cai, bao, zhong are all: left-falling stroke, and the codes are all: P;

[0099] The last stroke is: folding (L-shaped folding), and the code of the last stroke is used as its code, and the code is: L;

[0100] For jie, the last stroke is: vertical stroke, and the code is: H.

[0101] Some root characters can be regarded as combinations of several root characters. According to the combination rules, aliases are given to them, and they are coded according to the aliases. For example: nian, , the alias is: cao yi, and the codes are all: C, which is very convenient for understanding and memorization.

[0102] There are also the following special root characters:

[0103] 1. Zhui is the only root character with a single-person radical, and the code of the single-person radical is used as the code of this root character, and the code is: D.

[0104] 2. Root characters with the pronunciation of you. Since the pronunciation of you is very similar to the pronunciation of the English letter U, U is used as their code. For example: you, you, you, you, you, the code is: U.

[0105] 3. Special root characters: [yue X fan], such as: yue nv fan, yue guo fan. According to the characteristic points among them, they are respectively regarded as: nv, guo. For example: ying, split into root characters: wang, kou, nv, and the code is: WKV; luo, split into root characters: wang, kou, ri, mu, and the code is: WKRM.

[0106] The above classification of radicals improves the ease of remembering radicals and splitting Chinese characters.

[0107] In step 2 of the input method, the various radicals are used to split the Chinese characters to be input according to the stroke order of the Chinese characters, and a maximum of four radicals are selected from the split radicals.

[0108] Among them, the Chinese character splitting method includes: splitting according to the stroke order of Chinese characters, taking the largest stroke first, looking at the single stroke, giving way to the whole stroke if there are multiple strokes, using the missing strokes if there are missing strokes, giving way to all missing strokes, and not giving way to the correct strokes. The details are as follows:

[0109] 1. Split the radicals completely according to the writing order (stroke order) of Chinese characters. For example:

[0110] 国, split into: lower frame (1st and 2nd strokes), 王,丶,一. According to standard writing habits, characters with 囗 are written with the upper frame first, then the inside, and finally 一. Therefore, the closed frame radical 囗 is not used in the radical splitting.

[0111] Then, split it into: 一, 冂, and the 4th to 6th strokes. Among them, the 4th to 6th strokes are written with a vertical stroke first and then two horizontal strokes. They should be a combination of strokes, not the word 土.

[0112] Ran is divided into: 冂, 土. The strokes of the 3rd to 5th strokes are horizontal, vertical, horizontal, which is consistent with the writing of the word 土, so the root is 土.

[0113] 2. Give priority to the larger one.

[0114] Chinese characters are split into the largest radical in the radical table first. For example:

[0115] Hu can be divided into: gu, yue; but cannot be divided into: shi, kou, yue.

[0116] "容" can be divided into: "穴", "人", "口"; but it cannot be divided into: "宀", "谷".

[0117] Jiao, can be split into: Liu, Yi; but not split into: 亠, father.

[0118] However, the following situations are excluded.

[0119] 3. Look at each transaction individually.

[0120] For characters that have a single stroke and a radical connected together, try to separate the stroke and the radical, rather than combining the stroke with the following radical. For example:

[0121] 向, split into: 丿, 冂, 口. The first root is not split into: 丿, 丨 combination.

[0122] Yao, split into: 丿, big. The first root is not split into: 丿, a combination.

[0123] Xia, split into: 一,自,夂. The first root is not split into: 一,丿 combination.

[0124] Dare, can be divided into: 乛, 耳, 攵.

[0125] Note that here, single stroke means that the first stroke and the second stroke are of different types. If they are of the same type, they should not be considered as single strokes, but should be combined into multiple strokes. For example:

[0126] 蒙,冖below is: 一,豕. Since the first stroke of 一 and 豕 are of the same type of stroke, it does not conform to the principle of "single stroke looking down", and should be split into: 二,豕 (missing the first stroke).

[0127] In the word "余", the 3rd and 4th strokes are both horizontal, so it can be split into: 人,于,八; instead of being split into: 人,一,木.

[0128] 4. More non-integer.

[0129] When multiple-stroke combined radicals or non-whole-word radicals are connected to the following radicals, the integrity of the following radicals must be ensured when the radicals are split. For example:

[0130] 叱, split into: two dots, 酉; without combining the two dots and the horizontal line, the following root: 酉 is incomplete and is split into two or more smaller roots.

[0131] Umbrella can be divided into: person, two dots, and ten. Because if the two dots and the horizontal stroke are combined into a radical, only the last stroke (vertical stroke) will be left. In order to ensure the integrity of the last radical (not being split into single strokes), the last horizontal stroke in the combination of the two dots and the horizontal stroke is combined with the following vertical stroke to form the radical ten.

[0132] 敢, split into: 乛, 耳, 攵. If the first and second strokes form the left frame, the integrity of the following radical (耳) will be destroyed, resulting in the splitting of 耳 into two or more smaller radicals.

[0133] And, split into: two dots and one horizontal line, 廾; because after the horizontal line is combined with the two dots above, the bottom can still only be split into one radical.

[0134] "失" (loss) can be split into: a stroke and two horizontal strokes, which form "人" (person); because the root character: 人 (person) is still a complete root character.

[0135] 夬 can be divided into: left frame (composed of the 1st and 2nd strokes), 人; instead of being divided into: 折 (the 1st stroke), 大; because the left frame is not a whole character radical, and even if the following radical lacks the horizontal stroke of the 2nd stroke, the following radical is still a complete character radical: 人.

[0136] 5. If there is a shortage, use it; if there is a shortage, give way.

[0137] If the previous radical has missing strokes, use the missing strokes radical to ensure the integrity of the following radical. If the following radical has missing strokes radical, use the missing strokes radical to ensure the integrity of the previous radical. If there are missing strokes radicals before and after, use the missing strokes radical for the previous radical and the complete radical for the following radical. For example:

[0138] 遂, split into: two dots and one horizontal stroke, the 4th to 9th strokes (豕 is missing a horizontal stroke), 辶.

[0139] Island, divided into: strokes 1-4 (bird is missing one stroke), mountain.

[0140] 枭, can be divided into: 1st to 4th strokes (bird is missing a stroke), 木 (木 also has a root with a missing stroke).

[0141] 6. The correct characters are not given up.

[0142] For characters without missing strokes, this root cannot be separated. For example:

[0143] 电, split into:日,折. Because the radical:日, has no missing strokes, if its last stroke is added to the following 折, it will make it incomplete, so the last stroke can only be a stroke.

[0144] In step 2 of the input method, the method of selecting at most four radicals from the split radicals includes:

[0145] 1. When the number of split radicals is four or more, take the first, second, third and last radicals in sequence and discard the other radicals.

[0146] 2. When the number of split radicals is less than four, all radicals are taken in sequence. Sometimes, the last stroke radical of the Chinese character is also taken as the identification code. For example:

[0147] Yes, split it into the radicals: 又, 寸, and add the last stroke (dot) of the last radical as the identification code, so the code is: UCD;

[0148] Xin, split into the radicals: Li, Mu, Jin, coded as: LMJ, and the last stroke (vertical) of the last radical (Jin) can also be added as the identification code as needed, coded as: LMJH;

[0149] The character 宅 (zhai) is divided into the radicals 宀, 丿, 七, and is coded as BPQ.

[0150] Guan, split into radicals: the first to third strokes, 大, the last stroke (N) is the identification code, coded as: YDN;

[0151] 出, split into the radicals: 屮, 凵, the last vertical stroke (H) is the identification code, encoded as: UUH;

[0152] Umbrella, split into: person, 丷, ten, coded as: AYS.

[0153] 3. When the Chinese character to be input is a radical character, take the radical, the first stroke radical and the last stroke radical of the Chinese character in sequence. If the radical character has only one stroke, in addition to entering the code of the radical, you also need to enter a stroke of the radical. Sometimes, in order to make up three codes, you need to repeat the last code. For example:

[0154] 足, itself is a radical, its first stroke is vertical, and the last stroke is horizontal, so its code is: ZHN;

[0155] One, itself is a radical, its first stroke is horizontal, and there is only one stroke, so its code is: GG;

[0156] "乙" itself is a radical, and its code is Y. When used as a stroke, it is a fold, and its code is Z. Therefore, the code of the whole word is: YZ.

[0157] 丨, itself is a radical, its first stroke is vertical, and there is only one stroke, so its code is: HH. Sometimes it needs to make up three codes, so the last code H is added, so its code is changed to: HHH.

[0158] According to the above step 2, the Chinese character to be input is split and the code is obtained. In step 3, the key corresponding to the code is entered, that is, the key corresponding to the maximum four radicals is entered, and the input of the Chinese character is completed.

[0159] The radical encoding of this input method does not depend on the specific position of the letter keys in the keyboard, so it can adapt to various keyboard arrangements, such as the 9-grid keyboard and full keyboard of the pinyin input method.

[0160] In mobile devices, even if the full keyboard is used, the user still mainly types with the thumb, but each key is too small and inconvenient. Therefore, according to the characteristics of the input method, a special keyboard with 13 letter keys is proposed (see attached). Figure 8 ) and a special keyboard with 14 letter keys (see attached Figure 9 ).

[0161] like Figure 8 As shown, this special keyboard includes 13 letter keys, and 26 letters are distributed on the 13 letter keys in pairs in the order of the alphabet, and the key positions are arranged neatly.

[0162] like Figure 9As shown, this special keyboard includes 14 letter keys, which are arranged in three rows.

Claims

1. A new type of pure pen-shaped Chinese character input method, characterized in that, The input method includes the following steps: Step 1: Code the root radicals on the key positions of the information processing device. Among them, the types of root radicals include radical and stroke root radicals, whole-character root radicals, stroke root radicals, and combined root radicals. Among them, the code of the radical and stroke root radical is the initial letter of the pinyin of the general name of the radical. The code of the whole-character root radical is the initial letter of the pinyin of the character. Among them, the combined root radical is a root radical composed of multiple stroke root radicals. The types and codes of the combined root radicals are as follows: The combined root radicals do not include the combined root radicals ending with a dot or a right-falling stroke, nor the combined root radicals containing the stroke fold. Among them, the table of combined root radicals formed by the combination of single strokes and single strokes is as follows: The table of combined root radicals formed by the combination of single strokes and multiple strokes is as follows: The table of combined root radicals formed by the combination of the first, second, and third strokes connected end to end is as follows: Among them, the combination rules of the combined root radicals include: the fold stroke cannot be combined with other strokes; for the combined root radicals of strokes, the principles of intersection, connection, and adjacency shall be followed, and cross-combination across root radicals is not allowed; the combination of strokes cannot cross with other strokes again, otherwise it cannot be combined. Step 2: Use the various root radicals to split the Chinese character to be input according to the stroke order of the Chinese character, and select at most four root radicals from the split root radicals. Among them, the splitting rules include: splitting according to the stroke order of the Chinese character, giving priority to the larger radical, looking at single strokes, giving priority to the whole for multiple non-whole radicals, using the missing radical when there is a missing radical, giving priority to the lower radical when both are missing, not splitting the non-missing radical. Among them, the method of looking at single strokes is: for a character with a single stroke connected to a root radical, it is split into a single stroke and a root radical, rather than forming a combined root radical of single strokes with the next stroke of the single stroke and the root radical. Among them, the meaning of a single stroke is that the first stroke and the second stroke are of different types of strokes. If they are of the same type of strokes, it should not be considered a single stroke, but should be combined into a multiple stroke. Among them, the method of giving priority to the whole for multiple non-whole radicals is: when a multiple-stroke combined root radical or a non-whole-character root radical is connected to the following root radical, during the root radical splitting, the integrity of the following root radical should be ensured. Among them, the method of using the missing radical when there is a missing radical and giving priority to the lower radical when both are missing is: if the previous root radical has a missing radical, use the missing radical to ensure the integrity of the following root radical. If the following root radical has a missing radical, use the missing radical to ensure the integrity of the previous root radical. If both the previous and the following root radicals have missing radicals, use the missing radical for the previous root radical and the complete root radical for the following root radical. Among them, the method of not splitting the non-missing radical is: for a character without a missing radical, this root radical cannot be split. Among them, the method of selecting at most four root radicals is: when the number of split root radicals is four or more, sequentially select the first, second, third, and last root radicals; when the number of split root radicals is less than four, sequentially select all root radicals, and then select the stroke root radical of the last stroke of the Chinese character as the recognition code; when the Chinese character to be input is a root radical character, sequentially select the root radical, the stroke root radical of the first stroke of the Chinese character, and the stroke root radical of the last stroke; and Step 3: Press the keys corresponding to the at most four root radicals to input the Chinese character.

2. The novel pure pen-shaped Chinese character input method according to claim 1, wherein, The stroke root radicals and their codes are as follows:

3. The novel pure pen-shaped Chinese character input method according to claim 1, characterized in that The types of root characters also include nearly complete-character root characters and nearly radical root characters. The encoding of the nearly complete-character root characters is the encoding of the complete-character root characters similar to them, and the encoding of the nearly radical root characters is the encoding of the radical root characters similar to them.

4. The novel pure pen-shaped Chinese character input method according to claim 1, characterized in that, The types of root characters also include letter-like root characters. The encoding of the letter-like root characters is the letter. The letter-like root characters include the following root characters: root characters similar in shape to the letter, root characters with the first stroke similar in shape to the letter, and root characters with the last stroke similar in shape to the letter.
