Background

With the increasing demands on the miniaturization, portability and application range of the device, how to perform the function of a large keyboard with more than one hundred keys by using a small keyboard and surpass the input simplicity and the overall performance becomes a problem which needs to be properly solved. At present, for small devices such as mobile phones, PDAs, Pocket PCs, etc., all that is implemented by using 12 keys and adding additional function keys and conversion interfaces, there are many defects in inputting characters and symbols, for example, as follows:

when the numeric keys are used for inputting English, letters need to be continuously pressed by one to four times, for example, the letters need to be continuously pressed by four times when s is input; because the time of continuous keys needs to be accurately controlled, the operation difficulty is high, errors are easy to occur, and continuous input and continuous modification are often needed;

when the pinyin is input by adopting the numeric keys, a plurality of characters share one key, so that a large number of repeated code candidates and page turning search are caused, and time and labor are wasted;

when the Chinese strokes are input by adopting the numeric keys, the problems of few key pressing times and high resolution cannot be solved due to the limited number of the keys, doubt is caused by the variation of the stroke-type stroke order, the resolution is limited, a large number of coincident codes exist, and no character can be found after the stroke is frequently turned over for more than ten pages;

in addition, in the prior art, English/Chinese strokes/pinyin/numbers/symbols and other inputs are independent of each other; in use, when English, Chinese, symbols and numbers are mixed and applied, the input method needs to be switched continuously, which is very troublesome.

Because of the shortcomings of the existing small keyboard, if the convenience, flexibility, applicability and accuracy of the small keyboard input can be improved, the use feeling of the small equipment user can be optimized, and the miniaturization development of the large keyboard in other electronic fields can be facilitated.

Detailed Description

The invention provides a small keyboard character input method, which adopts 12 keys [0] - [9] and [ x ], [ # ] to replace a large keyboard so as to realize the arbitrary input of English major/minor letters, symbols, English words, pinyin strokes and numbers on a single interface. The following is illustrated by specific examples.

As shown in fig. 1, a flowchart of an embodiment of a keypad character input method provided by the present invention includes the following steps:

step A1, selecting and setting an input confirmation key, a number switching key and a pinyin tone auxiliary key in a keypad of 12 keys, wherein the number switching key is used for switching continuous number input; the method can be specifically as follows:

setting [1] as an input confirmation key;

setting [ ] as a digital switching key;

setting [. X]、[0]And [ #]For auxiliary keys of phonetic tone [. X [ ]]Corresponding to yin being equal to one, [0]]Corresponding to yang peace and upward voice

，[#]Corresponding to removing sound and removing stroke.

In addition, other key functions can be set according to requirements, for example, the [1] is set as a space key.

Step A2, distributing code elements for [0] - [9] and [ x ], [ # ] keys, wherein the key code elements comprise numbers, letters, stroke etymons and/or symbol type prompt code elements, and the letter, stroke etymons and symbol type prompt code elements are not overlapped with the input confirmation key, the number switching key and the pinyin tone auxiliary key so as to realize the distinction of different input objects after coding;

specifically, in order to take account of the inherent key habit, the step a2 may be configured as shown in fig. 2, where italic numbers represent keys and the content behind the numbers shows part of symbols, specifically as follows:

setting keys of [0] to [9] to correspond to numbers of 0 to 9 respectively, which is an inherent habit formed in long-term use;

setting abc, def, ghi, jkl, mno, pqrs, tuv and wxyz in 26 letters on keys [2], [3], [4], [5], [6], [7], [8] and [9] respectively;

arranging the stroke etymons on [4], [5], [6], [7], [8] and [9], and sequentially comprising a +, a Koushan, a Yutian,  , and a small Go; wherein, the radicals contained in the stroke radicals belong to the keys of the stroke radicals, such as the (a) part is included in the (a) part corresponding to [4], the (a) part is included in the (mountain) part corresponding to [5], the (rain) part corresponding to [6] includes the (Jiong) part, (field) part includes the (ten) part, (7) part corresponding to () () includes the (vertical) part, (8) part corresponding to () () includes the () part, () part and (stroke) part, (9) part corresponding to (small) includes the (eight) () part, (ge) part includes the (an ancient type of spoon) part and the () (フ) part; therefore, the stroke etymons can also be expressed as "+ -, koushan, rain Jiong tiandeca,  , , xiaoygo an ancient type of spoon.

In conclusion, the stroke radicals corresponding to each key are [4] horizontal, [5] vertical, oral, [6] tenth, Tian, [7] left-falling, [8] dot, right-falling, [9] turning and dividing. As long as the stroke etymons shown in FIG. 2 are marked on the actual keyboard, the user can easily segment the Chinese characters according to the character splitting principle without special memory.

Symbol class cue symbols, which indicate symbol classes and include a superscript symbol indicated by [2], a separator symbol indicated by [3], a left arrow indicated by [4], and the like, are set on [2] - [9], [0], and [ # ], and are illustrated in detail in the following. In fig. 2, representative symbols in each group of symbols are marked on the keyboard as symbol category prompt symbols, and the rest are hidden, so that the user can determine the key corresponding to the input symbol according to the prompt.

In particular, in fig. 2, "E" corresponding to [1] represents an input confirmation key Enter.

Step A3, corresponding to each letter, distributing a large/small letter scattered key on the keypad, corresponding to each symbol type prompt code element, and distributing a symbol scattered code element on the keypad;

the large/small letter dispersion keys include an english letter dispersion key and a pinyin letter dispersion key, and specifically, the distribution of the large/small letter dispersion key and the symbol dispersion key is described by way of example according to the symbol setting shown in fig. 2, as shown in fig. 3A to 3K, embodiments of keys [2] [3] [4] [5] [6] [7] [8] [9] [ # ] [0], ] are given in sequence, and specifically include:

setting English letter dispersion keys: the lowercase letters after splitting corresponding key letters are sequentially arranged on the [2] [5] [8] [0] key, and the uppercase letters after splitting corresponding key letters are sequentially arranged on the [3] [6] [9] key; setting a pinyin letter dispersion key: the split phonetic alphabets of corresponding key alphabets are sequentially arranged on the keys of [2] [5] [8] [0], wherein the initial letter dispersion key with h suffix is arranged on the English alphabet dispersion key of the corresponding capital letter.

As shown in fig. 3A, [2] is both the letter dispersion key for the pinyin a and the letter dispersion key for the letter a; [9] is not only the letter dispersion key of the Pinyin ch, but also the letter dispersion key of the letter C.

One embodiment of a keyboard arrangement incorporating large/small letter scatter keys and symbol scatter symbols is shown in FIG. 3A, key [2]]The symbol of (2) includes a number 2, a letter abc, and a symbol category hint code ("meshed °"), the upper/lower case letter dispersion key corresponding to the key is: [2]Corresponds to a, [5]]Corresponds to b, [8]Corresponds to c, [3]Corresponds to A, [6]]Corresponding to B, [9]Corresponding to C and ch; the symbol dispersion symbol corresponding to the key includes: [4]Corresponding superscript'²”，[7]Corresponding superscript'³”，[*]Corresponding superscript'^o", and [0]Corresponding arrow "×".

In another embodiment, as shown in fig. 3E, the symbol of the key [6] includes the number 6, the letter mno, the stroke etymon "yutian" and the symbol type prompt code ("→/"), and the upper/lower case letter scatter key corresponding to the key is: [2] corresponding to M, [5] corresponding to N, [8] corresponding to O, [3] corresponding to M, [6] corresponding to N, [9] corresponding to O; the symbol dispersion symbol corresponding to the key includes: [7] the corresponding "/", [ ] corresponds to "\\, [0] corresponds to" → ", and [ # ] corresponds to" ^ a ".

For simplicity, for some single-code stroke Chinese characters, the corresponding stroke radicals can also be directly arranged on the keys as single-code characters, as shown in fig. 3E: [1] corresponding to "ten" and [4] corresponding to "rain".

Through the above steps, the symbol setting as the basis of the input character is completed.

Step A4, establishing mapping relation between each key and code element, for making the input of each key trigger the processor to identify the corresponding code element.

Next, in order to implement any shuffle, a step of compiling a code table is required to be performed so that keys input in a certain order are matched to only or limited candidates, namely:

step a5, compiling a code table from the set keypad, the code table being called by the processor to display the target character of the entered code.

In order to realize the distinguishing of the mixed input method by using the distinguishing set code elements and the corresponding auxiliary keys, the code table specifically comprises:

(1) english upper/lower case letter code part: the keys of the letters, the input confirmation key and the large/small letter dispersion key are arranged in sequence;

taking the code element set shown in fig. 2 and 3 as an example, the english code is a large/small letter scatter key corresponding to the key + [1] + where the letter is located; for example, the code for A is [2] [1] [3].

(2) English word coding part: sequentially arranging a key where the first letter is located, a letter dispersion key for designating a trigger mode and keys where the second to sixth letters are located, and taking an input confirmation key as the last code when the number of the first letter is less than seven;

for example, the code of the compiler switch is that the key [2] + double-click of the alphabet dispersion key corresponding to C is performed to double-click the key [6] + o [6] + m [6] + p [7] + i [4] +1 [5] - [2] [99] [6] [7] [4] [5 ].

Preferably, the compiling of the english word code table further includes:

setting ter and t as equivalent codes, and omitting the ter when the ter is met; under the repeated exploration, high-frequency prefix letter strings respectively corresponding to hundreds of words, such as inter, connector and the like, are found to contain ter, so that the ter is covered by t, and the characters can be effectively solved by crossing the high-frequency prefix letter strings;

the high-frequency prefix is simply coded in a spanning code mode, for example, trans can be coded according to t, and then two codes are sequentially taken to finish coding, because the high-frequency prefix trans corresponding to about 220 characters is simplified into the t code, and the high-frequency prefix trans spanning is finished by taking 2 codes subsequently, and other letters can be completely omitted; such as: the transcondinal can be coded as trans [8] + t letter discrete key [22] + c [2] + o [6] + [1] + 8] + [22] + [2] + [6] + [1 ].

The spanning codes are set according to actual requirements, and quick input is realized; because the input is not contradicted with the normal input, even if the input is forgotten to be used, the input display can be realized according to the conventional way.

(3) Chinese phonetic coding part: sequentially a key with the first letter, a letter dispersion key, a key with the subsequent letter and a pinyin tone auxiliary key;

it can be seen that the problem of duplication codes can be reduced by the scatter key and the pinyin tone auxiliary key. Meanwhile, the pinyin tone auxiliary key can also distinguish Chinese pinyin from English word codes.

(4) The Chinese stroke coding part: the Chinese character units are divided according to the appointed rule, the key of the stroke etymon corresponding to the starting stroke is arranged, and the input confirmation key is used as the last code.

Under the condition that the single code is set, the code of the single code can be a stroke etymon-located key, an input confirmation key and a single code character-located key in sequence, for example, a single code character 'mountain' is input, as shown in fig. 3D, the code of the single code character is a stroke 'mountain' located etymon [5] + input confirmation key [1] + single code character 'mountain' located key [4 ]; the other single-code character input methods are similar and are not described in detail herein.

In general, Chinese character splitting is carried out according to specified rules; however, since the existing Chinese character splitting rules are various, the present invention is described by taking an example, and a person skilled in the art can understand that, as long as 6-key etymon allocation can be realized, it is ensured that English/Chinese/symbol codes are not confused, and the specific splitting rule does not affect the technical scheme provided by the present invention. In this example, the Chinese stroke code table is composed of the steps of splitting Chinese characters and coding.

Wherein, for the condition that the strokes are separated from left to right, the strokes are separated into a plurality of units by taking the gap of the separated strokes as a boundary, and the etymon formed by starting the strokes of each unit is called as a 'head'; taking the first codes of the first four units in the order from left to right to perform coding;

for the case of no stroke separation from left to right, called single head, the first four stroke units are taken according to the stroke order to perform coding.

It can be seen that each chinese character is split into at most 4 codes, and the remaining components are no longer included in the code:

such as "" located "" capable of being broken "" into "" フ "" capable of being broken "" horizontal "" must be broken "" フ "" horizontal "" tea "" capable of being broken "" "" ten "" vertical "" horizontal "" capable of being broken "" フ "" vertical "".

In the splitting process, due to the fact that the idle radical combination is used, obvious advantages are shown, such as the radical "  ", the high upper side word can be directly decomposed into " mouth", namely, "mouth", "main" can be decomposed into " eleven", "vertical" can be decomposed into " one", one ", and" six "can be decomposed into" eight ", and the like. It can be seen that is the same radical, which can eliminate the doubts of the two oblique directions such as the ever and the valley; for another example, the "comparing" component "an ancient type of spoon" may have different starting strokes due to the writing habits of different users, and if the components are separated according to the complete stroke, it is difficult to disambiguate the input method; meanwhile, in the component an ancient type of spoon of ' ratio ' and ' differentiation ', whether one stroke needs to distinguish horizontal or left-falling strokes or whether two strokes need to distinguish crossing or not needs to be considered in the stroke type splitting process, but the etymon an ancient type of spoon ' provided by the invention solves the problems through one etymon.

In this step, for the case that the first unit has more than one stroke etymon, the key of the second stroke etymon of the first unit is added as the complement code during the coding. I.e. when the first unit has more than one code, a code should be supplemented, such as "" can be decomposed into "," second(s) can be supplemented into "フ", "Liu" can be decomposed into "," フ "," Liqu "can be decomposed into" フ "," horizontal "" フ "," "can be decomposed into" フ "フ".

For the condition that the single radical of the Chinese character to be coded is represented as a left upper part or a right upper part semi-enclosed corner radical, coding is carried out on the corner radical and the first two stroke components of the rest parts;

namely, when the split component is the first component of the corner covering part, the first code is taken to be recorded into the code. For example, "deer" is from (wide) part, the first code is ", the second code takes the content except (wide) part, it is" フ "; for another example, "" is selected from () part, the first code is "|", the second and third codes are selected from () parts, and are "field"; also for example, the "steam" emerges from the portion, the first code being "horizontal", the second and third codes being " ten". And 3 codes can complete the coding under the condition that the corner shielding radical component exists.

For the condition that the Chinese characters to be coded contain a totally-enclosed structure, coding the totally-enclosed structure according to two conditions of strokes in the totally-enclosed structure and no strokes in the totally-enclosed structure; when a stroke longitudinally penetrates through the totally-enclosed structure from the middle, the totally-enclosed structure in the middle is cut off up and down, namely the Chinese character to be coded is separated into an upper unit, a middle totally-enclosed unit and a lower unit, and the units after being cut off are coded from top to bottom;

for example, "men" can be decomposed directly into "Tian (12501s)" without hesitation "and/or" Heng ", thereby degrading ambiguities; for another example, "car" can be broken down into "ten fiend ten", and "field" in the middle; 'A' can be split into 'field I'; "Shen" can be decomposed into "|".

The totally-enclosed structure like 'day', 'song' and 'field' is called as 'real opening', therefore, the rule can be also called as 'real opening cutting and penetrating'.

Then entering the step of encoding: for each unit, coding is carried out in sequence according to the key where the stroke etymon corresponding to the starting stroke of the unit is located, and the coding is finished by an input confirmation key; for each stroke component, the keys where the corresponding stroke etymons are located are sequentially coded, and the input confirmation key is used for ending. As can be seen from the splitting process, since the number of the components participating in the encoding is not more than 5, the final splitting is not more than 5 codes and less than 7 codes, and finally an input confirmation key is added.

In order to improve the actual input efficiency, Chinese words and even sentences can be set during stroke coding, and the invention utilizes the following rules to code:

for two-character Chinese, the Chinese strokes are encoded into four first codes and three second codes in turn, for example, hong Kong can be divided into Xiang (Pan ) and hong Kong (the first and the second codes);

for long sentences of three-character Chinese and Chinese with more than four characters, the Chinese stroke codes are first four codes, [2] and last two codes in sequence; wherein [2] represents the meaning of followed by two characters or sentences; for example, "Hongkong" can be resolved into "Xiang" (Pan fields, etc. + -.) + 2 "+" Hongkong "(s), etc.; "the particular administrative site government of hong Kong" may be encoded as "incense" (Ten fields, bottom to bottom) + [2] + "the particular administrative site government of hong Kong" (, bottom to bottom);

for four-character Chinese, the Chinese strokes are encoded in the order first four codes, [3] and last two codes, wherein [3] represents the meaning of the following three characters, e.g. "hong Kong government" may encode "xiang" (e.g. +/- field) + [3] + "gang government" ("H").

It can be seen that the radical combination mode provided by the invention does not need to distinguish straight rows and horizontal rows, connected split bodies, left hook and right folding and pen crossing and connecting, and is realized on six keys, thereby being convenient for touch typing. Overall, the coding provided by the invention has the following advantages:

1. adopting idle combined stroke etymons; such as "" from "フ" rather than "and", "relieving pressure of the" overloaded "and" off "" and "eight" from written doubt;

2. the word number is evenly distributed to each key and the stroke shape is distributed;

3. the shape system of each first code is adopted, so that the phenomenon of repeated codes caused by partial isomorphism is avoided, and the consideration of stroke order is reduced;

4. with very high resolution, 6 keys can be calculated by taking 5 codes at most, and 6 × 7776 groups can be combined to resolve 6000 words, and the ratio is 1.5: 1, so 40% no duplicate codes can be determined and no page-change lookup is needed; in contrast, both "changjie" and "universal five-stroke" input methods require 26 keys to be used, and 13060 words are analyzed by the combined quantity of 26 × 26 ═ 11,881, 376 in 5 codes, and the ratio is 910: 1, it is necessary to recite a large number of hidden etymons (the etymons are invisible on the finger key surface), and the page change is still required, so that the Chinese stroke provided by the invention has high resolution and convenient use.

Further to address the situation where a single-repeat code is generated due to high resolution, a preferred embodiment further includes that the code table further includes a complementary code encoding portion, associated with the chinese stroke encoding portion and the chinese pinyin encoding portion, including: for any Chinese stroke/pinyin code, under the condition that a single-repetition code exists, the most frequently used character is used as a non-repetition code to be coded, the next frequently used character is set as a complementary character, a mapping relation is established between the complementary character and an input confirmation key of a specified triggering mode, the input confirmation key is used as a complementary code input key, and the non-frequently used character is triggered when the single-repetition code exists; for example, the codes of 'money' and 'bank' are the same, and are single codes, the common characters 'money' are directly displayed during use, and the 'bank' needs to be called out by long pressing of 1 to replace the common characters 'money' displayed on the screen. Generally, the input confirmation key displays the alternate code when the input of the chinese character is completed and the simplex code is generated.

In order to reduce the interference of rare words and ensure that rare words can be searched, the code table is divided into a common code table and a rare code table, only the common code table is triggered when the common code table is normally input, and the rare code table is triggered by the alternative code keys. For example, setting [ # ] as an alternative code key, editing 7000 rare words with the usage rate lower than 8% in a rare word code table, and enabling the rare words to fall back to the background; when no target to be input exists in the conventional alternative words, rare words can be called out by using [ # ] and selected by a user; rare words may be set in an auxiliary function as will be discussed later.

(5) Symbol code table part: and sequentially prompting the key where the code element is located, the input confirmation key and the key where the symbol dispersed code element is located for the symbol type.

Step A6, inputting the needed codes to the processor one by one, and distinguishing English letters, English words, Chinese pinyin, Chinese strokes, symbols and numbers by the processor according to the code table, wherein the method comprises the following steps:

english letters, symbols and Chinese stroke single code words are all input confirmation keys by using the second code, and are distinguished from other codes; furthermore, the third code is respectively corresponding to a letter scattered key, a key where a symbol scattered code element is located and a single code word to realize the distinguishing;

english words, the second code input of which is a letter dispersion key of a specified triggering mode, are distinguished from other codes;

numbers that are switched by a specified trigger without confusion, e.g., by [ ], and then successive inputs are all numbers; inputting the code after the operation according to the x;

the Chinese strokes are similar to the Chinese pinyin, but the Chinese pinyin needs to pass through a pinyin tone auxiliary key finally, and the pinyin tone auxiliary key is not overlapped with the keys where the strokes are located, so that coding differentiation is realized.

Through the steps, the user can realize the arbitrary mixed typing of English capital and small case letters, symbols, English words, Chinese pinyin, Chinese strokes and numbers on a single interface without conversion, and partial input contents are more than those of the existing large keyboard.

It can be understood by those skilled in the art that although the above-mentioned preferred embodiment of the keypad character input method has been described by taking the determined key settings as an example, but not limited thereto, any setting that meets the requirements of the present invention for mapping keys and symbols can achieve the above-mentioned effects, and it is covered by the technical solution of the present invention, for example, shifting all symbols and auxiliary, switching keys, etc. of the preferred embodiment of the present invention backward by one bit in sequence, i.e., [1] original setting is completely mapped to [2], [2] to [3]. and [ # ] original setting is completely mapped to [1], and the technical effects of the present invention can be achieved as well.

Further, in order to implement all functions of the large keyboard on the 12-key keypad, a preferred embodiment further includes setting a designated triggering mode for each key of the keypad, where the triggering mode includes double-click triggering, long-press triggering, and/or double-key co-press triggering; step a4 further includes setting a mapping relationship between the key activation manner and the corresponding function.

For example, the double click trigger comprises: setting keys [1], [2], [3], [4], [5], [6], [7], [8], [9], [0] and [ # ] in the case of digital input, double-clicking triggers the F1-F12 function, as shown in fig. 4; a double-click on the set key [1] triggers the Delete function, as indicated by ". D" on the key [1] in FIG. 2, which represents a double-click Delete (Delete);

the long press trigger comprises: is provided withKey [2]]、[4]、[6]、[8]Long press triggers cursor to move up, left, right and down; setting [. X]、[0]、[#]Long press triggers shift, ctr1 and alt respectively; is provided with [3]Switching of the long press trigger Assistant interface, shown as in FIG. 2 "F"; the specific long press triggered keypad case is shown in fig. 5;

the double bond co-press trigger comprises: setting a key [5] to be respectively pressed together with keys [1], [2], [4], [6], [7], [8], [ ]and [ # ], and sequentially triggering Esc, PgUp, Back Space, Delete, tab, PgDn, Caps and Space;

the above setting is also only exemplary, for example, PgUp can be set to [5] and [3] in common, and PaDn can be set to [5] and [9] in common, as shown in FIG. 6.

The above example indicates that a long press of 3 may trigger the switching of the auxiliary interface, which may be set as follows: setting each key to establish mapping relation with telephone dialing, Internet, European character input, secondary common symbol, common/rare character library setting, simple and complex character setting, phonetic notation input and/or usage guide interface. Referring to fig. 7, an embodiment of an auxiliary interface is shown. It should be noted that the setting of rare words and single-repeated common words is done in the word stock setting.

In the above-mentioned auxiliary interface, by clicking the corresponding key, the corresponding interface can be entered.

As shown in fig. 8, an embodiment of an internet interface is shown, wherein a local map is displayed, and the local map is divided into 10 areas marked and respectively corresponds to [0] - [9]10 keys, and an internet information icon is obtained by selecting areas → selecting industries → classifying industries → business names or websites, so that no website is required to be clicked at all.

Generally speaking, the system has auxiliary interfaces including the Internet, the European, the phonetic notation, the regional word stock and the like, and can meet the requirements of different people.

In summary, the keypad character input method provided by the invention is particularly suitable for micro-miniature devices such as mobile phones, palm processors, handheld camcorders, network information, regulation and control instructions and the like. The small keyboard is beneficial to the integration of small equipment, auxiliary tools or additional auxiliary keys are not needed, and the full-function replacement of the large keyboard can be realized.

Furthermore, the invention also provides a full-function input method of the 6-key equipment, which has the similar working principle as a 12-key keyboard. Referring to fig. 11A, a schematic diagram of a preferred symbol arrangement of a 6-key keypad is shown, wherein a long press on [3] switches to the interface shown in fig. 11B, and characters are input by different input methods through interface selection.

In summary, the present invention mainly provides a 12-key keypad character input method, and for the sake of understanding, the following describes an example of the processing and displaying process of the keypad input.

Firstly, identifying a triggering mode of a key;

the default interface is a main interface and is used for recognizing the mixed input of Chinese pinyin/strokes, English letters/words, symbols and numbers. However, when a specific trigger mode is received, the interface is switched to meet the requirements of people in different regions and the requirements of full-function keys. For example, when the main interface is just initialized, or after the last input is finished, the following inputs will trigger the corresponding interfaces: and when the long-time press input of the key [3] is detected, switching between the main interface and the function interface: when the current interface is the main interface, switching to a functional interface; and when the current interface is the functional interface, switching back to the main interface.

In addition, when the [2], [4], [6] and [8] long press input is detected, the results of upward movement, left movement, right movement and downward movement of the cursor are displayed; when detecting the long press input of the keys [ + ], [0], [ # ], displaying shift, ctrl and alt functions;

when the key [5] is detected to be simultaneously input with the keys [1], [2], [4], [6], [7], [8], [ ]and [ # ], the functions of Esc, PgUp, Back Space, Delete, tab, PgDn, Caps and Space are sequentially triggered and displayed;

and, detecting the double-pressing input of the key [1], deleting the previous input; the F1-F12 functions are triggered when double-click inputs of keys [1], [2], [3], [4], [5], [6], [7], [8], [9], [0] and [ # ] are detected in the case of numeric input.

Further, when the current interface is a function interface, key input is detected, and telephone dialing, internet, European input, next common symbols, common/rare word stock setting, simple and complex body setting, phonetic notation and/or usage guidance interfaces are respectively displayed. Particularly, when the current interface is an internet interface, key input is detected, and internet connection to the area corresponding to the key is established.

As the main point of the present invention, in order to realize the recognition of mixed typing of different input methods, the processing display of the keypad input provided by the present invention focuses on the processing under the main interface, as shown in fig. 12, including:

b1, when the current interface is the main interface, recognizing the first key input, when the non-numeric switch key, displaying the letter dispersion key and the symbol dispersion code element corresponding to the key, in some cases, displaying the chinese stroke single code word, as shown in any of fig. 3A-3K, and executing step B21; if the number is the numeric shift key [ ], executing the step B22;

it can be seen that after the input recognition process of this step is completed, the numbers and other characters are distinguished;

if [1] is set to also serve as a space key, a space is displayed when the first key input is recognized as [1] under the host interface. At this time, the input of the [1] key is under the main interface, so that the input does not conflict with the function of the key as an input confirmation key, and the recognition confusion of the processor is avoided.

B21, recognizing the second key input:

when the confirmation key is input, continuously displaying the scattered code elements of the large and small letters and the scattered code elements of the symbols corresponding to the first key, and in some cases, displaying the Chinese stroke single code word, and executing the step B31;

when the letter is a scattered letter key in a designated triggering mode, displaying an English character window, and executing the step B32;

otherwise, go to step B33;

it can be seen that through the recognition of the second key input, the english letters, symbols and stroke single codes can be used as a group, the english words can be used as a group, and the chinese strokes and the chinese pinyin can be respectively determined as a group.

B31, English letters, symbols and stroke single codes are possible, so that a third key input is recognized, the symbols corresponding to the input keys or large and small English letters or Chinese single code strokes are displayed on the screen, and the step B5 is executed;

b32, displaying the subsequent input in the character-composing window, executing step B5 after the input confirmation key or the 7 th code;

b33, possibly Chinese pinyin or Chinese stroke, recognizing the input confirmation key at last, displaying the alternative Chinese, and executing step B40; recognizing the last pinyin tone auxiliary key, displaying the alternative Chinese, and executing the step B41;

in the step, the pinyin input and the stroke input can be finally distinguished by identifying the tone auxiliary key; when the first codes are input, the pinyin codes and the stroke codes are possibly superposed, and at the moment, the character combination window displays the key numbers;

b40, displaying the selected stroke Chinese character, and executing the step B5;

b41, displaying the selected Chinese pinyin, and executing the step B5;

in steps B40 and B41, a preferred embodiment includes:

and detecting whether the next input is a long-press input confirmation key [1], if so, replacing the common characters which are already displayed by the replaced characters with the same codes on the screen, and otherwise, taking the next input as the input of B1.

Detecting whether the next input is the input of the alternative code key [ # ], if so, displaying a rare character code table; otherwise the next input is taken as input to B1.

B22, clicking to input, and displaying the input numbers in sequence; if double-click input is performed, the F1-F12 functions corresponding to the input numbers are sequentially displayed, and when the number switching key is detected again, the step B5 is executed;

and B5, ending, and returning to the main interface.

By the processing and displaying example of the keypad input, it can be seen that the keypad coding method provided by the invention can identify the mixed input of Chinese and English letters/words, symbols, Chinese pinyin/strokes and numbers on the main interface without repeated switching; meanwhile, all the code words are visible on the key surface for a long time without memorizing, and page-changing searching is avoided to a great extent through step-by-step identification of the code words; moreover, the requirements of people in different regions can be met.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that even if the technical solutions of the present invention are modified or substituted by equivalents, the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention.
