Keyboard based on letter combination keys and input method

Technical Field

The invention belongs to the technical field of keyboard design, and particularly relates to a keyboard based on letter combination keys and an input method.

Background

Currently, keyboards are roughly classified into american keyboards, european keyboards, japanese keyboards, and the like, wherein the american keyboards are single-letter keyboards and are designed for being suitable for multi-industry applications. When Chinese characters are input by means of American keyboard, the Chinese phonetic alphabet is formed from initial consonants and final consonants, and few phonetic alphabets are formed from only final consonants, three of the initial consonants are double-letter, 29 of the final consonants are multi-letter, and maximum number of letters is 4. Therefore, the American keyboard, which is a single-letter keyboard, is not suitable for the rapid input of Chinese Pinyin. The multi-industry applicability design of keyboards also results in many keys on the keyboard being left idle for a long period of time for a particular user.

The inventor finds that when a single-letter keyboard is adopted for inputting Chinese characters, the input speed is greatly reduced due to unfamiliar reasons such as the keyboard and pinyin, for example, when students in the stage of learning Chinese characters or old people with limited culture level use computers, the single-letter keyboard is adopted for inputting Chinese characters, so that the input speed of Chinese characters is very inconvenient and the input speed of Chinese characters is very slow; at present, in order to improve the input speed, a mode of adding letter combination keys on the basis of a single-letter keyboard appears to improve the input speed of Chinese characters, however, the mode of adding letter combination keys on the basis of the single-letter keyboard at present only adds the common letter combination mode to the existing keyboard strongly, and the use habit of different crowds on the keyboard is not considered, so that the result of inadaptation when the single-letter keyboard is normally used and the keyboard with the letter combination keys is encountered is caused, and the experience of a user is greatly reduced; and when the letter combination keys are added, the influence of the added keys on the whole volume of the keyboard is not considered, and the relation between the body quantity of the Chinese character and the number of the newly added letter combination keys is not considered, so that the problem of overlarge keyboard volume is caused, or the problem that the number of the letter combination keys cannot meet the input of all Chinese characters is solved.

Detailed Description

The invention will be further described with reference to the drawings and examples.

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

Example 1:

at present, the mode of adding the letter combination keys on the basis of the single-letter keyboard is only to add the common letter combination mode to the existing keyboard, and the use habit of different crowds on the keyboard is not considered, so that the consequence that the normal use of the single-letter keyboard is not suitable when the keyboard with the letter combination keys is encountered is avoided, and the experience of a user is greatly reduced; and when the letter combination keys are added, the influence of the added keys on the whole volume of the keyboard is not considered, and the relation between the body quantity of the Chinese character and the number of the newly added letter combination keys is not considered, so that the problem of overlarge keyboard volume is caused, or the problem that the number of the letter combination keys cannot meet the input of all Chinese characters is solved.

In view of the above, the present embodiment provides a keyboard based on alphabetic combination keys, including a plurality of single alphabetic keys, a plurality of alphabetic combination keys, and a plurality of function keys;

wherein, a plurality of letter combination keys are independently arranged, or a plurality of letter combination keys and a plurality of function keys share one key; the number of the letter combination keys is determined according to the maximum number of key presses allowed when the Chinese pinyin is input.

The use habit of different crowds on the keyboard is considered, and the crowds who normally use single-letter keys and the crowds who have requirements on letter combination input are satisfied; in addition, the number of the letter combination keys is determined according to the maximum number of keys allowed when the Chinese pinyin is input and fully spelled by different people, the relation between the body quantity of the Chinese characters and the number of the newly added letter combination keys is considered, the problem that the keyboard volume is overlarge due to the fact that the number of the letter combination keys is increased too much under different requirements is avoided, the problem that the number of the letter combination keys cannot meet the input of all Chinese characters is also avoided, for example, the Chinese pinyin can be obtained after the Chinese pinyin is mastered for many times, the setting data of the letter combination keys can be reduced on the basis of increasing the typing times, the maximum typing times when the Chinese pinyin is mastered for the worse people to obtain one Chinese character can not be increased through the number of typing times, and the mode of increasing the number of the letter combination keys is adopted to reduce the maximum typing times when the Chinese character is obtained.

It should be noted that, the keyboard in the present invention refers to two types of physical keyboards and virtual keyboards; the physical keyboard refers to an independent keyboard and an embedded keyboard, such as a keyboard of a notebook computer, a keyboard embedded in an instrument device and the like, and the virtual keyboard is also called a screen keyboard, and refers to a keyboard displayed on a touch screen, a display screen or the like.

The keyboard with letter combination is provided with letter combination keys besides the existing keys, wherein the letter combination keys refer to keys for inputting two or more letters into the processor in sequence by pressing one key on the keyboard, for example, four letters of 'i', 'o', 'n' and 'g' can be sequentially input by pressing a letter combination key 'iong'. The content of the letter combination key is the whole (such as zh, sh, ang) or part (such as ng) of the initial or final of the Chinese phonetic alphabet, or the root or common letter combination (such as audi, tion, sion) of other language characters such as English.

The specific implementation process of the embodiment is as follows:

alternatively, the alphabetic combination key is an independent key, for example, the alphabetic combination key "iong" key is a newly added independent key, and four letters of "i", "o", "n" and "g" can be sequentially input by pressing the alphabetic combination key "iong" key; or the letter combination key is a second function key, for example, the letter combination key 'iong' key is a second function key of an 'F2' key, when the letter combination key is the second function key, a letter combination key opening key and a letter combination key closing key are also arranged, the letter combination key opening key and the letter combination key closing key are independent keys, for example, a 'combination' key is newly added, when the 'combination' key is pressed for the first time, the letter combination key is opened, the 'F2' key is pressed, four letters of 'i', 'o', 'n' and 'g' can be sequentially input, and when the 'combination' key is pressed for the second time, the original function of the 'F2' key is executed; or the letter combination key opening key and the letter combination key closing key are combination keys, for example, an 'Alt' + 'K' combination key is defined as a letter combination key opening key and a letter combination key closing key, when the 'Alt' + 'K' combination key is pressed for the first time, the letter combination key is opened, the 'F2' key is pressed, four letters of 'i', 'o', 'n' and 'g' can be sequentially input, when the 'Alt' + 'K' combination key is pressed for the second time, the 'F2' key is pressed, the original function of the 'F2' key is executed, and when the letter combination key is a second function key, the hardware design of the original keyboard can be not changed, and the method can be realized only through software.

As shown in fig. 1, the physical keyboard in the present embodiment includes a control circuit board, keys, a base plate, a panel, an interface, and the like. The control circuit board is a control core of the whole keyboard, is positioned in the keyboard and mainly serves as a key scanning identification, coding and transmission interface for work; it converts the numbers or letters represented by the individual keys, etc., into signals recognizable by a computer.

The coded physical keyboard with the letter combination keys also comprises a hardware encoder, wherein the hardware encoder generates a key code number or a key value and inputs the key code number or the key value into the processor; the screen keyboard with the letter combination keys comprises a touch screen keyboard and a non-touch screen keyboard; the keyboard with the letter combination keys comprises a two-key full-spelling keyboard, a three-key full-spelling keyboard, a four-key full-spelling keyboard, a multi-key full-spelling keyboard and the like; the realization of the letter combination key, the physical keyboard and the screen keyboard can be realized by adding new keys. For a physical keyboard, this may also be achieved by defining the second function by means of existing keys.

The letter combination content of the letter combination key is fixed or settable; when the letter combination content of the letter combination key is settable, letter combination key content editing software is arranged, the letter combination key content editing software is opened, the interface displays the existing setting content of each letter combination key, the change button is clicked, the content of each letter combination key can be edited, and after the editing is completed, the confirm button is clicked, and the content of the letter combination key is updated.

Optionally, the letter combination key on the physical keyboard is provided with a letter combination key content display device, and the letter combination key content display device is an LED display screen.

By adopting the traditional keyboard, the Chinese phonetic alphabet with six letters is input by full spelling, six times of keys are needed to be pressed, time and labor are wasted, and the input efficiency is low. The keyboard with letter combination is adopted, the number of key presses is reduced, chinese character information is input quickly, a large amount of time and manpower resources can be saved, the prior art is completely supported, and the realization is easy.

The two-key full-spelling keyboard, namely when the maximum number of key presses allowed when inputting Chinese phonetic alphabets is twice, the letter combination method is as follows:

the Chinese phonetic input method is mainly used for inputting Chinese characters by a keyboard, the Chinese phonetic input method takes an important role, the alternative characters given during the whole spelling Chinese phonetic input are the least and the most accurate, the Chinese characters which want to be input are obtained most quickly, according to the rule of the Chinese phonetic scheme, the Chinese phonetic comprises 21 initial consonants, two zero initial syllables with vowels and 33 vowels, the Chinese phonetic corresponds to the letters with the same font as English letters, and the Chinese phonetic corresponds to v in the English letters, otherwise, in the whole spelling Chinese character input process, since the initial consonants of the u, the u and the un are not overlapped, the u e and the u can be replaced by the u and the un.

The pinyin of a Chinese character includes one to six letters, for example, one letter such as a, two letters such as an, da, etc., three letters such as yan (smoke), sha (sand), etc., four letters such as shan, diao, sha, etc., five letters such as jiang, xiong, shang, shaan, etc., six letters such as shang, etc.

As shown in tables 1 and 2, the intersection points of the columns of the initial consonants and the rows of the final consonants in the tables are marked with 1, which can form Chinese pinyin, and the other cases are marked with 1, which cannot form pinyin. Wherein, the non-initial and single-letter initial in table 1 includes b, p, m, f, d, t, n, l, g, k, h, j, q, x, r, z, c and s.

TABLE 1 non-initial and single-letter initial pinyin table

TABLE 2 Pinyin Table of double-letter initial consonants (zh, ch, sh) and zero initial consonants (y, w)

Wherein, the pinyin structure is shown in table 3:

TABLE 3 Pinyin structure list

The number of pinyin keys is shown in table 4 and table 5, wherein the intersection point of the row where the initial consonant is located and the row where the final is located is marked with 0, which is the number of pinyin keys which cannot form the pinyin, and other cases are the number of pinyin full-spelling keys. The non-initial and single-letter initial include b, p, m, f, d, t, n, l, g, k, h, j, q, x, r, z, c and s.

Table 4 non-initial and single-letter initial phonetic key-press table

TABLE 5 double letter initial (zh, ch, sh) and zero initial (y, w) Pinyin key-press table

As can be seen from tables 1, 2 and 3, if the Chinese phonetic alphabet can be fully spelled by implementing the keys at most twice, and the number of the letter combination keys is minimized, the double-letter initials zh, ch and sh are required to be respectively made into the letter combination keys, and the multi-letter finals an, ao, ai, ang, ong, ou, en, er, ei, eng, ia, iu, ie, in, ing, un, ua, uo, ue, ui, iao, ian, iang, iong, uai, uan and uang are also required to be respectively made into the letter combination keys.

Therefore, the two-key full-spelling keyboard refers to a keyboard with keys at least comprising 21 initial keys, two zero initial syllable keys with vowels and 33 vowels; the 21 initial keys refer to a b key, a p key, an m key, an f key, a d key, a t key, an n key, an l key, a g key, a k key, an h key, a j key, a q key, an x key, a z key, a c key, an s key, an r key, a zh key, a ch and a sh key, wherein the zh key, the ch key and the sh key are letter combination keys, and the number of the three keys is three; the two zero initial syllable keys with vowels refer to a y key and a w key;

33 final keys refer to an, ao, ai, ang, o, ong, ou, e, en, er, ei, eng, i, ia, iu, ie, in, ing, u, un, ua, uo, ue, ui, iao, ian, iang, iong, uai, uan, and uang keys, wherein an, ao, ai, ang, ong, ou, en, e, in, iu, ie, i, ia, iu, ie, in, un, ua, ian, ng, iono, i, n, and uang keys are a combination of letters, 27.

Pressing any one of the letter combination keys can sequentially input a plurality of letters, for example, pressing a 'zh' key, sequentially inputting two letters of a 'z' and a 'h' and pressing an 'hong' key, sequentially inputting four letters of an 'i', 'o', 'n' and a 'g', wherein the zh, ch, sh and an, ao, ai, ang, ong, ou, en, er, ei, eng, ia, iu, ie, in, ing, un, ua, uo, ue, ui, iao, ian, iang, iong, uai, uan keys and the uang keys are collectively called a two-key full-spelling keyboard letter combination key; thus, a Chinese character can be fully spelled by pressing the key at most twice, for example: the q key and the iong key are pressed, and the full spelling of the 'Qiong' word can be realized by pressing the keys twice, and five keys of the q key, the i key, the o key, the n key and the g key are pressed by utilizing the traditional keyboard; three-fifths of keys are saved; the full spelling of the 'sand' word can be realized by pressing the sh key and the a key twice, and three keys of an s key, an h key and an a key are needed to be pressed by utilizing the traditional keyboard; one third of the key number is saved; the full spelling of the 'corner' word can be realized by pressing the j key and the iao key twice, and four keys of the j key, the i key, the a key and the o key are needed to be pressed by utilizing the traditional keyboard; saving two-fourth (one-half) of the keys; the full spelling of the "brush" word can be realized by pressing the "sh" key and the "ua" key twice, and the four keys of the s key, the h key and the u key a key are needed to be pressed by utilizing the traditional keyboard; saving two-fourth (one-half) of the keys; the full spelling of the refreshing word can be realized by pressing the 'sh' key and the 'uang' key twice, and the six keys of the s key, the h key, the u key, the a key, the n key and the g key are needed to be pressed by the traditional keyboard; saving four (two-thirds) of keys.

The 21 initial keys, the two zero initial syllable keys with vowels and the 33 vowels are arranged in any order or in the order shown in fig. 1 or fig. 2. Wherein, the arrangement mode shown in figure 1, the initial consonant keys and the zero initial consonant syllable keys with vowels are concentrated at the left side of the keyboard, the vowels are concentrated at the right side of the keyboard, and are arranged according to the Chinese phonetic order, so that the Chinese phonetic order is convenient for memorizing and is convenient for right-hand dominant (right-handed person) to use; the arrangement mode shown in fig. 2, wherein the initial keys and the zero initial syllable keys with vowels are concentrated on the right side of the keyboard, the vowels are concentrated on the left side of the keyboard, and the arrangement mode is arranged according to the Chinese pinyin order, so that the Chinese pinyin is convenient to memorize and is convenient for a left-handed dominant person (left-handed person). The two-key full-spelling keyboard has the advantages that the number of key presses is small, full-spelling input can be realized by pressing any Chinese character twice at most, the defects are that the number of letter combination keys is large, zh, ch, sh keys and an, ao, ai, ang, ong, ou, en, er, ei, eng, ia, iu, ie, in, ing, un, ua, uo, ue, ui, iao, ian, iang, iong, uai, uan, uang keys are needed to be added, 30 keys are needed to be added, challenges are brought to learning, habit and the like of a user, when the keyboard is realized in a mode of adding keys, the circuit design of a physical keyboard circuit board is difficult, the screen area occupied by a screen keyboard is overlarge, the keyboard is realized in a mode of a second function key, and the keyboard is almost impossible to realize by using the existing keyboard.

The three-key full-spelling keyboard, that is, the maximum number of keys allowed when inputting Chinese phonetic alphabets is three, is shown in tables 1, 2, 3, 4 and 5, and the number of phonetic keys is mainly caused by double-letter initials and multi-letter finals. The double-letter initial consonants zh, ch and sh are respectively made into letter combination keys, so that one-time key input of the initial consonants is realized, and three letter combination keys are added; the first and last two letters ia, io, ua, ng of the four-letter final iang, iong, uang are respectively made into letter combination keys, and the four-letter combination keys are added to realize the maximum three-time key input of the Chinese pinyin full spelling. The number of pinyin keys added to the seven-letter combination key (zh, ch, sh, ia, io, ua, ng) (hereinafter, referred to as seven-letter combination key) is shown in tables 6 and 7.

Four-letter final iang, iong, uang, wherein the first two letters of iang and uang respectively form final ia and ua and also respectively form the first two letters of final iao, ian, uai, uan, wherein none of the first two letters and the first three letters of iong form other final, and only the last three letters form final ong, so that letters ia, ong, ua, ng are respectively made into letter combination keys, and four letter combination keys are added. Thus, the pinyin keys with the number of seven letter combination keys (zh, ch, sh, ia, ong, ua, ng) (hereinafter, seven multi-letter combination keys) added are shown in tables 8 and 9, and the pinyin full-spelling is realized by inputting the pinyin at most three times with the least number of letter combination keys added. The non-sound and single-letter initials after adding seven double-letter combination keys comprise b, p, m, f, d, t, n, l, g, k, h, j, q, x, r, z, c and s.

As can be seen from tables 8 and 9, after seven multi-letter combination keys are added, the maximum key number of a single pinyin is 3, and the requirement that the Chinese pinyin is fully spelled by three keys is realized; meanwhile, the total key number is reduced by (1031+318) times- (895+226) times = 228 times, and the full pinyin input efficiency is further improved remarkably.

Taking 3500 common words in a modern Chinese common word list as an example, after the tone is removed from the office default pinyin of 3500 common words, the number of keys input by adopting the traditional keyboard is compared with the number of keys input by adopting the keyboard with seven double-letter combination keys and seven multi-letter combination keys added, and the comparison is shown in a table 10.

As can be seen from Table 10, the input efficiency of the pinyin for 3500 Chinese characters in common use can be significantly improved by adding seven alphabetic combination keys. And after seven multi-letter combination keys are added, the full spelling input efficiency of 3500 commonly used Chinese characters can be further obviously improved.

Therefore, the three-key full-spelling keyboard refers to a keyboard with keys at least comprising 26 English letter keys and seven letter combination keys; the 26 english letter keys refer to an a key, a b key, a c key … … x key, a y key and a z key, the seven letter combination keys refer to a zh key, a ch key, a sh key, an ia key, a ua key, an io key and a ng key, or a zh key, a ch key, a sh key, an ia key, a ua key, an ong key and a ng key, and a plurality of letters can be sequentially input by pressing any one of the seven multi-letter combination keys, for example, pressing the zh key, sequentially inputting two letters of "z" and "h" and pressing the io key, and sequentially inputting two letters of "i" and "o"; the Chinese pinyin corresponds to the letters of the same font as the English letters, v in the English letters corresponds to u in the Chinese pinyin, and vice versa.

zh key, ch key, sh key, ia key, ua key, io key, ng key, or zh key, ch key, sh key, ia key, ua key, ong key, ng key, collectively referred to as three-key full-spelling keyboard letter combination key, so that full-spelling can be realized by pressing the key at most three times, for example: pressing the q key io key and the ng key for three times to realize the full spelling of the 'Qiong' word, and pressing five keys of the q key, the i key, the o key, the n key and the g key by utilizing the traditional keyboard; saving two-fifths of keys; the full spelling of the 'sand' word can be realized by pressing the sh key and the a key twice, and three keys of an s key, an h key and an a key are needed to be pressed by utilizing the traditional keyboard; one third of the key number is saved; by pressing the j key, the ia key and the o key, the full spelling of the 'corner' word can be realized by three keys, and four keys of the j key, the i key, the a key and the o key are needed to be pressed by using the traditional keyboard; the number of the keys is saved by one fourth; by pressing the 'sh' key and the 'ua' key, the full spelling of the 'brush' word can be realized by two keys, and four keys of an s key, an h key and a u key a key are needed to be pressed by the traditional keyboard; saving two-fourth (one-half) of the keys; by pressing the 'sh' key, the 'ua' key and the 'ng' key, the whole spelling of the 'refreshing' word can be realized by three keys, and six keys of an s key, an h key, a u key, an n key and a g key are needed to be pressed by the traditional keyboard; saving three-sixths (one-half) of keys; the zh key, the ch key, the sh key, the ia key, the ua key, the io key and the ng key are arranged, so that not only is the Chinese character input time-saving and labor-saving, but also the efficiency is high, and the Chinese character input method can play a similar role in the input of English or other languages, because the combination of 'zh', 'ch', 'sh', 'ia', 'ua', 'io' and 'ng' also exists in the words of the languages.
