Description

Virtual keyboard based on touch screen and input method

Technical Field

The invention relates to a virtual keyboard and an input method based on a touch screen, in particular to a virtual keyboard and an input method based on a touch screen.

Background

With the development of science and technology, touch screens are widely applied, the touch screens are not only output devices but also input devices, the devices are generally applied to electronic products such as mobile phones and tablet computers, and characters such as characters, symbols or numbers are input to the electronic products through the touch screens, so that the application of the devices is realized.

In a specific application, a virtual keyboard needs to be simulated on a touch screen, and most of the existing virtual keyboards simulate a PC keyboard from a typewriter or a T9 keyboard from a touch-tone telephone. When the two types of keyboards are applied, the following defects exist: when inputting english, the top row of the PC keyboard has 10 letter keys, resulting in small virtual keys, and users often have wrong keys, and although the T9 keyboard has large virtual keys, each key represents multiple letters, so the accuracy is low, and multiple clicks are needed. When Chinese is input, the problem is more prominent, and both the T9 keyboard and the PC keyboard need to be clicked for inputting Chinese words. When the Chinese input has coincident codes, the word candidate column of the existing input method can contain too few candidate words. For the above reasons, the accuracy and the input speed of the existing input method are not satisfactory, and a virtual keyboard and an input method based on a touch screen are urgently needed to meet the higher requirements of people.

Disclosure of Invention

The present invention is directed to solving the above problems and providing a virtual keyboard and an input method using a touch screen.

the 5 th row of letter keys are sequentially from left to right: [ u bond ], [ v bond ].

The 5 th line of the English lower case interface and the English upper case interface is an English other key area, and 1 switching key and 3 editing keys are formed.

A mark is arranged on the upper side of the space key of the other English key regions, the upper case ↓isdisplayed on the English lower case interface, and the lower case ↓isdisplayed on the English lower case interface.

And thirdly, the symbol interface comprises a class group key area, a symbol key area and a general other key area, wherein keys in the symbol key area are 'symbol keys', the symbol key area can slide transversely to turn pages to display more symbols, the symbol key area slides leftwards to turn pages backwards, and the symbol key area slides rightwards to turn pages forwards. When the page needs to be turned backwards, the page 1 can be turned backwards by sliding from right to left in the 1 st to 3 rd rows of the symbol keypad; the page can be turned to the last page by sliding from right to left in the 4 th line; when the page needs to be turned forward, the page 1 can be turned forward by sliding from left to right in the 1 st to 3 rd rows of the symbol keypad; sliding from left to right in row 4 may flip to the first page.

The keys in the class group keypad are class group keys and clicking or sliding from the class group keys can switch between different classes and groups.

The symbols are divided into 4 groups, each group has 4 types, and 16 types are shown in the following:

group 1 includes: chinese punctuation, English punctuation, radicals, emoticons;

group 2 includes: mathematical symbols, unit symbols, serial numbers and special symbols;

group 3 includes: phonetic symbols, phonetic notation symbols, phonetic symbols, Latin letters;

group 4 includes: japanese hiragana, japanese katakana, russian letters, greek letters.

The class group key has a class name bit and a group number bit, the number on the class name bit represents the class number of the group, for example, "2-4" represents the class 4 of the group 2, and the Chinese character is the abbreviation of the class name, for example, "winning the bid" represents the Chinese punctuation. The characters of the group number positions on the 4 class group keys are all from top to bottom: group 1, group 2, group 3, group 4, which each represent group 1, group 2, group 3, group 4.

Clicking the class group key can switch the symbol key area to the class corresponding to the class name abbreviation on the key class name position; sliding up from the class group key can switch the class group key region to the group corresponding to the group number on the key group number position.

The upper 4 rows of the numeric character interface are numeric character key areas which comprise 10 numeric keys and 14 symbolic keys.

According to the input method of the virtual keyboard based on the touch screen, when virtual keys are used for inputting, a user can click, namely press and then release the keys, or slide, namely move and then release the keys after pressing, and the sliding mode comprises short sliding and long sliding, wherein the short sliding is only used for longitudinal sliding, and the long sliding is only used for transverse sliding.

Firstly, the Chinese input mode is pinyin input, clicking sound selection, and longitudinally sliding to select characters, words and sentences.

Clicking on the "minutes" key in the Chinese initial interface may enter a "no initial" sound (i.e., a zero initial that is not the beginning of y and w).

The initial key is clicked in the Chinese initial interface, the interface is switched to the Chinese final interface, the final key is clicked below the Chinese final interface, the interface is switched back to the Chinese initial interface, and the process can be repeated circularly.

Specifically, the process of inputting Chinese includes the following steps:

the background of the input method is provided with a character word stock, each character or word has two attributes, namely corresponding 'tone' and use frequency number, a user clicks back and forth between an initial consonant interface and a final interface, and the interface is switched back and forth between a Chinese initial consonant interface and a Chinese final interface.

the invention will make these initials and finals to form "sound" according to the order of "first sound and last rhyme", then call the word or character corresponding to these "sound" from the "word stock", and display on the initial key or final key according to the order of the number of characters and the frequency of use, when there are more "sounds", the corresponding words will be automatically combined, and all will be displayed on "the top first position".

and thirdly, the user can input the display result by pressing the display result and sliding longitudinally, and during the period, the user can turn pages by sliding transversely so as to display more candidates.

Through sliding, the input of the candidate word is as follows:

the characters, words and sentences displayed by the upper lexeme can be input by sliding upwards from the initial keys or the final keys; when the letter key slides downwards, the single character displayed in the lower character position can be input.

The top most front is responsible for recording the 'sound' formed by combining all the initial consonants and the final consonants clicked before the non-sliding input, and displaying the sound in a Chinese form.

After sliding input, the sound corresponding to the input content is subtracted from the top front position, and the back sound is displayed in a Chinese form continuously, at the moment, the user clicks the initial consonant key and the final sound key again, and the sound combined by the system is added to the back and is displayed in a Chinese form all the time; if the displayed content of the top most digit of the slide input is input, namely all 'tones' are input, the top most digit will return to the initial state.

The upper word positions are arranged in a front-back order according to the number of words and the use frequency (word frequency/word frequency); all the upper lexemes except the top most lexeme only show the existing words in the word stock, which correspond to the "sound" of the first few or first words shown at the top most lexeme at that time.

The lower word position is divided into lines according to tone and then the single words are arranged according to the utilization rate (word frequency/word frequency); the individual characters displayed in the lower case correspond to the "sound" of the first character displayed in the most preceding case at that time.

When Chinese is input, page turning is carried out on the candidate words:

under the Chinese initial interface, the upper word position and the lower word position can display more candidate words through page turning, and the page turning is achieved through transverse sliding.

The page can be turned to the last page by sliding from the right to the left in the 1 st to the 3 rd rows and from the right to the left in the 4 th row; the page may be turned forward by 1 page by left-to-right scrolling in rows 1 to 3, and to the first page by left-to-right scrolling in row 4.

Under the interface of Chinese vowels, the horizontal sliding can be used for turning pages; lines 1 to 4 are slid laterally to turn a page forward or backward, and line 5 is slid laterally to turn the first or last page.

After the function is set, the horizontal sliding can also be used for canceling the last clicked initial consonant and returning to the initial consonant interface under the Chinese vowel interface.

Secondly, the English input mode in the invention is as follows:

under the English lowercase interface, pressing letter keys can input English lowercase letters, sliding upwards from letter keys can input English uppercase letters, sliding downwards from letter keys can input symbols, and the 'u key' and 'v key' are used as exceptions.

Under the English capital interface, pressing the letter key can input English capital letters, sliding upwards from the letter key can input English lowercase letters, sliding downwards from the letter key can input symbols, with the exception of the [ U key ] and the [ V key ].

Thirdly, the symbol input mode in the invention is as follows:

the keys in the symbol keypad are symbol keys and clicking on a symbol key can input a symbol. The symbol keypad slides transversely to turn pages to display more symbols, the leftward sliding is page turning backwards, and the rightward sliding is page turning forwards; when the page needs to be turned backwards, the page 1 can be turned backwards by sliding from right to left in the 1 st to 3 rd rows of the symbol keypad; the page can be turned to the last page by sliding from right to left in the 4 th row, and when the page needs to be turned forward, the page can be turned forward by sliding from left to right in the 1 st to 3 rd rows of the symbol keypad; sliding from left to right in row 4 may flip to the first page.

Clicking or swiping from the class group key may switch different classes and groups: clicking the class group key can switch the symbol key area to the class corresponding to the class name abbreviation on the key class name position; sliding up from the class group key can switch the class group key region to the group corresponding to the group number on the key group number position.

Fourthly, the input mode of the number symbol (number and mathematical symbol) in the invention is as follows:

clicking any key of the number symbol key area can input corresponding number or symbol, sliding upwards or downwards from the number key or symbol key, and inputting more symbols.

Fifthly, the method for editing and inputting the blank, comma and period in the invention is as follows:

the deletion, the input of the space and the extraction can be respectively realized by clicking the [ deletion key ], [ space key ], [ enter key ] in other key areas or other English key areas. A comma can be input by sliding up from the [ character boundary key ], and a period can be input by sliding up from the [ English boundary key ].

Sixthly, the interface switching and setting functions are as follows:

(1) in the general other key areas or English other key areas, clicking the symbol interface key can be switched to the symbol interface; clicking the [ English world key ] can switch to an English lower case interface or an English upper case interface; clicking the middle limit key can switch to the Chinese initial interface; sliding up from the middle key can switch to the numeric symbol interface.

(2) When the English lower case interface and the English upper case interface are switched, the Chinese initial consonant interface, the symbol interface or the number-symbol interface is required to be switched to the symbol interface, so that 'other common key regions' appear under the interfaces.

The space key slides upwards, so that the switching between an English lower case interface and an English upper case interface can be realized; through the setting of the function, the space keys of other general keypads are also provided with the marks, if the space keys are marked as the capital letters ↓ ", the English world key is clicked from other general keypads of other interfaces to switch to the English lowercase interface, and when the space keys are marked as the lowercase ↓", the English world key is clicked from other interfaces to switch to the English uppercase interface. If no such mark is set on the space bar of other general key areas in the function, clicking the English key area from other general key areas of other interfaces will always switch to the English lower case interface.

(3) In the interface of the Chinese vowel, if switching to other interfaces is required, the interface should be switched back to the interface of the Chinese vowel, and similarly, switching from other interfaces to the interface of the Chinese vowel needs to pass through the interface of the Chinese vowel.

(4) Sliding up from [ delete key ] may set "function".

The invention has the beneficial effects that:

in the invention, all interfaces use the same virtual keyboard layout with 5 rows and 6 columns, and a user can find a clicking or sliding position according to habits after being familiar with the virtual keyboard, so that part of burden of eyes of the user can be relieved, and the comfort level of the user in use is further improved. Each key on the virtual keyboard is larger than that of the PC type virtual keyboard, and is not easy to click by mistake; the meaning of clicking each key is single, and the input is more accurate than that of a T9 keyboard. In the symbol interface, the classes and the groups can be switched by clicking and sliding on the class group keypad, pages can be turned in a transverse sliding mode, a user can find a symbol desired by the user in the shortest time, the letter arrangement modes of the two English interfaces and the Chinese and initial consonant interface are from the 4-line arrangement mode of 'letter song' which can be detailed by the user, the user can feel like a great acquaintance, and the user can quickly become familiar with the virtual keyboard.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

1. interface in the invention

As shown in fig. 1, the virtual keyboard of the present invention forms rectangular interfaces, specifically forms four interfaces of "chinese interface", "english interface", "symbol interface", and "number-symbol interface", each interface forms 5 rows and 6 columns, and 30 rectangular units in total, and each unit forms a virtual key. For the virtual key, a user can click, namely press and then release the virtual key, or slide, namely move and then release the virtual key after pressing, wherein the sliding modes comprise short sliding and long sliding, the short sliding is only used for longitudinal sliding, and the long sliding is only used for transverse sliding, so that the reduction of the misoperation rate is facilitated.

The English interface comprises an English lowercase interface and an English uppercase interface, and the initial interface of the English interface is the English lowercase interface.

Wherein, the symbol interface is the symbol interface.

Wherein, the number symbol interface is the number symbol interface.

The virtual keys on each interface are called 'key areas' together according to attributes, each virtual key also comprises a plurality of functional positions, namely 'positions', the virtual keys are arranged in the 'symbol interface' to form 'groups' and 'classes', one 'group' comprises 4 'classes', and the interface, the key areas, the keys, the positions, the groups and the classes are formed integrally.

According to the reading and writing habits from top to bottom and from left to right, when the form-factor interface is in the position of the form-factor interface, the front means that the displayed line number is close to the top and the position is close to the left, and the rear means that the displayed line number is close to the bottom and the position is close to the right. When referring to the "front-back relationship", the upper and lower priority row numbers and the left and right positions are determined. Reference to

lines

1, 2, 3 … …, also numbered from top to bottom;

lines

1, 2, 3 … …, also numbered from left to right.

2. "general other keypad" and "English other keypad".

As shown in fig. 2, wherein, the 5 th row of the chinese initial consonant interface, the symbol interface and the symbol interface is a general other keypad, forming 3 switching keys and 3 editing keys; as shown in fig. 3, the 5 th row of the english lowercase interface and the english uppercase interface is an english other keypad, and 1 switching key and 3 editing keys are formed. Wherein, the [ sign boundary key ], [ middle boundary key ], [ English boundary key ] forms a switching key which is used for the mutual conversion among four interfaces of 'Chinese interface', 'English interface', 'sign interface' and 'number-sign interface'.

2.1, switching between interfaces.

Clicking the [ sign boundary key ] can switch to the sign interface; clicking the [ English world key ] can switch to an English lower case interface or an English upper case interface; clicking the middle limit key can switch to the Chinese initial interface; sliding up from the middle key can switch to the numeric symbol interface.

The English lowercase interface and the English uppercase interface can not be directly switched to the symbol interface, if the symbol interface is required to be switched, the common other key areas appear under the interface through a Chinese initial consonant interface or a numeric symbol interface.

A mark is arranged on the upper side of the space key of the other English key regions, the upper case ↓isdisplayed on the English lower case interface, and the lower case ↓isdisplayed on the English lower case interface. The space key slides upwards, so that the switching between the English lower case interface and the English upper case interface can be realized. Through the setting of the function, the space keys of other general keypads are also provided with the marks, if the space keys are marked as the capital letters ↓ ", the English world key is clicked from other general keypads of other interfaces to switch to the English lowercase interface, and when the space keys are marked as the lowercase ↓", the English world key is clicked from other interfaces to switch to the English uppercase interface. If no such mark is set on the space bar of other general key areas in the function, clicking the English key area from other general key areas of other interfaces will always switch to the English lower case interface.

The interface switching method has the advantages that no other general key regions or English other key regions exist under the Chinese vowel interface, the interface switching method needs to switch back to the Chinese initial interface when the interface switching method is required to switch to the other interface, and similarly, the interface switching method from the other interface to the Chinese vowel interface needs to pass through the Chinese initial interface. The mode of switching to the Chinese vowel interface is to click an initial consonant key, and the mode of switching from the Chinese vowel interface back to the Chinese initial consonant interface is to click a vowel key.

2.2 use of edit keys

Clicking the [ delete key ], [ space bar ], [ Enter key ], has the same effect as clicking the "delete key" (← Backspace), "space bar", "Enter key" (Enter) on the PC.

"comma" can be input by sliding up from [ character boundary key ], and "period" can be input by sliding up from [ english boundary key ].

Sliding up from [ delete key ] may set "function".

2.3 setting of "function".

As described above, the upward slide from [ delete key ] can be set in "function", and items that can be set are as follows:

(1) height of each key on the virtual keyboard.

(2) And whether to display and use the function of lower character position in the Chinese initial interface.

(3) Whether the initial state of the Chinese initial interface enables the upper word position and the lower word position to display the default words or not, if the default words or the default words are enabled, the default words are high-frequency words or self-defined words, and a user can self-define the words of the upper word position and the lower word position.

(4) Whether the initial state of the Chinese initial interface enables a special appearance (e.g., different shape, different color or "skin"), etc.).

(5) In the interface of the Chinese vowel, whether the function of horizontal sliding is started or not, if the function of horizontal sliding is started, horizontal sliding means that candidate words are turned over, or means that the last initial consonant is deleted and returned to the interface of the initial consonant (only sliding from left to right).

(6) Typically, whether the upper side of the space bar of other key areas displays the capital and lower case marks.

(7) After the Chinese initial interface is switched to the symbol interface, the symbol key is clicked to input the symbol, and whether the Chinese initial interface is switched back automatically or not is judged.

(8) When the display content is in the top most position, if the space key is clicked, the space is input, the top most position content is input, or the top most position content is input and the space is added.

(9) When the display content is displayed at the top most front position, the user can carry out the calling, input the content at the top most front position or input the content at the top most front position again.

(10) When the top most front position has display content, if switching to other interfaces, the content in the top most front position will be input or discarded.

(11) whether fuzzy is turned on and fuzzy rules are defined, e.g., N and L, K and G, H and F, R and L, zh and Z, ch and C, sh and S, an and ang, ian and iang, ua and uang, en and eng, in and ing, etc. (note that if R and L are defined to be fuzzy with each other, input Rui or Lv will display all Rui and Lu words simultaneously)

(12) whether v is used to replace us, ue is used to replace us, ü n and ü n are mixed, and uun and us are mixed.

(13) after choosing the initial consonant J, Q, X, Y, whether ü is considered to be ü.

(14) When inputting Chinese, the input of simplified Chinese is still complex.

(15) When inputting, inputting character of 'half angle' or 'full angle'.

(16) Whether to enable "cloud" auxiliary input. If enabled, under what network environment. (Applicant does not claim the right of "cloud" auxiliary input)

3. A Chinese input method.

The Chinese input mode of the scheme belongs to pinyin input and adopts an input mode of clicking to select sound and longitudinally sliding to select characters (words and sentences).

As shown in FIG. 4, the Chinese initial interface has two key regions, namely an initial key region and other general key regions, and as shown in FIG. 5, the Chinese final interface has 5 key regions, including an a-rhyme key region, an a-intermediate key region, an o-rhyme key region, an e-rhyme key region, an i-rhyme key region and a u ü key region, and all the keys in the 6 key regions can be called final keys.

The keys in the initial keypad are initial keys, 4 rows and 24, which represent 23 initial consonants of the chinese pinyin and 1 "fractional note" for inputting "no initial" sounds (i.e. zero initial consonants other than the beginning of y and w), such as input: the Chinese characters of On, Kao and Yi are denoted by the notation "fen".

The user clicks the initial key under the Chinese initial interface, the interface is switched to the Chinese final interface, the final key is clicked under the Chinese final interface, the interface is switched back to the Chinese initial interface, and the process can be repeated circularly.

As shown in fig. 6, the procedure for inputting chinese is as follows:

and thirdly, the user can input the result by pressing the result display key and sliding longitudinally, and during the period, the user can turn pages by sliding transversely so as to display more candidates.

3.1, displaying candidate Chinese characters, words and sentences on the virtual keyboard:

as shown in fig. 7, the consonant keys are composed of 3 parts: the lower left corner is the initial consonant of the Chinese phonetic alphabet, which is the initial consonant position; the lower right corner is a lower word position; the upper side of the key is the upper lexeme, the first upper lexeme is also called the forefront, and the forefront can display multiple words or sentences.

The initial position, the lower word position and the upper word position can be mutually represented by character forms with different forms (namely different sizes, thicknesses, colors, fonts, gradients, background colors, smoothness, embellishments and the like) so as to be conveniently and quickly distinguished by a user.

As shown in fig. 8, the vowel key is composed of an upper part word and a lower part vowel, and similarly, the first upper part word is the top most front.

The top most front is responsible for recording the 'sound' formed by combining all the initial consonants and the final consonants clicked before the non-sliding input, and displaying the sound in a Chinese form. After sliding input, the sound corresponding to the input content is subtracted from the top most front position, and the back sound is displayed in Chinese form, at this time, if the user clicks the initial consonant key and the final sound key again, the sound combined by the system is added to the back most and is displayed in Chinese form all the time. If the most front bit of the slide input shows the content, i.e. all "tones" are input, the most front bit will return to the initial state. The upper word positions are arranged in a front-back order according to the number of words and the use frequency (word frequency/word frequency); all the upper lexemes except the top most lexeme only show the existing words in the word stock, which correspond to the "sound" of the first few or first words shown at the top most lexeme at that time.

The initial keypad has exactly 4 rows of initial keys:

the lower letter position of the initial key in row 1 lists only the single words with "yin-Ping" (minus) and light (not tone),

the lower letter position of the consonant key in the 2 nd row only lists the single character with the tone of "yang ping" (negative),

the lower letter bits of the 3 rd row of the initial keys only list the single words with the tone "up" (ˇ),

the lower letter position of the 4 th row of the initial keys only lists single characters with the tone of ' going-down ' (').

The words and phrases in the word stock have their own frequency of use numbers, i.e., the frequency of words or phrases in general, with words and phrases having higher frequencies of use ranked further forward. For the words displayed in the lower words, the word frequency numbers can be permanently fixed, the front and back sequence can not be changed due to the statistics of the different use frequency caused by the personal use condition of the user, and therefore the user can remember the positions of a part of the words after the user is proficient in using the scheme.

Two examples of the invention are shown below:

(1) as shown in fig. 9, after the [ sh initial consonant ] is clicked on the Chinese initial consonant interface, the [ ou rhyme ] is clicked on the Chinese final interface, then the [ J initial consonant ] is clicked on the Chinese initial consonant interface, the [ i rhyme ] is clicked on the Chinese final interface, and finally the situation is returned to the Chinese initial consonant interface.

The upper word positions are firstly arranged according to the word number of the word, the front is the word of 2 words, and the rear is the word. For the word position, the system selects the long word first, then selects the short word, and finally selects the word, and the word is numbered according to the use frequency when the number of the words is the same. The word "handset" is used more frequently than "remembered" and therefore "handset" is ranked in front of "remembered". Similarly, the word "hand" is used more frequently than "bow", so that the word "hand" is arranged in front of the word "bow".

Each lower word bit. Wherein shou has no light sound, and only the tone of the 2 words "receiving" and "missing" is "flat" (so that the lower character bit in the 4 letter keys after the 1 st row has no single character; shou 'yangping' (corresponds to only 1 character, so there is no single character at the 5 lower positions after row 2.

(2) If only one tone is provided, namely the initial key and the final key are clicked once respectively, the upper part of a word only displays a word, but the arrangement mode of the single word displayed by the word and the lower part of the word may be different because the upper part of a word does not take the tone factor into consideration.

As shown in fig. 10, taking yi sounds as an example, the difference between the upper and lower word positions can be easily seen:

if the user does not like to see or use the lower character position, the user can set the lower character position in the function.

3.2, display of the multi-word phrase or sentence at the top most level:

if the number of words input by the input method is large, or when a sentence is input, the last word position, especially the first position, may occupy a plurality of initial consonant keys or vowel keys, even occupy a whole line or a plurality of lines of initial consonant keys or vowel keys.

As shown in fig. 11, 12 and 13, the cases of occupying 2, 3, 4, respectively, of the initial keys are:

when the upper part of a word or a sentence occupies a plurality of initial keys or final keys, the word or the sentence can be input by sliding upwards from any initial key or final key occupied by the upper part of a word.

In general, the sequence of the display contents of the word positions is arranged according to the number of words, the words with more words are arranged more forward, and when a sentence is input, the whole sentence is arranged at the top most position; words as many as the number of words are arranged according to the usage rate. However, if the lexeme length of the remaining keys in a row is not sufficient to accommodate the next word, the word is moved to the lexeme display on the keys of the next row or page, and the lexeme of the "remaining keys" is selected for the next accommodated word or word display. This mechanism is to save display space.

As shown in fig. 14: the 'revolutionary traditional education' is an existing word in a word bank, the word has 6 words and should be arranged at the 2 nd, but the 2 nd upper word position is positioned on the last 1 initial consonant key in the 2 nd row and cannot accommodate the word with 6 words, so the 'revolutionary traditional education' can only be displayed at the 3 rd row and occupies 2 initial consonant keys. The "traditional revolution" that should be ranked at line 3 has 4 words and cannot be squeezed into the 2 nd upper lexeme, so it can only be displayed at line 3, following the "traditional revolution education". The 4 th revolution which should be arranged originally has only 2 words and can just be put into the 2 nd upper word position, and the 5 th song name follows the traditional revolution or the 5 th revolution.

3.3, page turning of candidate words in Chinese input:

under the Chinese initial interface, the page turning can make the upper and lower word positions display more alternative words and phrases, and the page turning is achieved by transverse sliding.

As shown in fig. 15 and 16, the page may be turned back by sliding right to left in the 1 st to 3 rd rows and turned to the last page by sliding right to left in the 4 th row; the page may be turned forward by 1 page by left-to-right scrolling in rows 1 to 3, and to the first page by left-to-right scrolling in row 4.

Under the interface of Chinese vowels, the horizontal sliding has two different meanings, and a user can select one of functions and set the function.

The first arrangement is to use the same meaning of horizontal sliding in the Chinese vowel interface as in the Chinese initial interface, i.e. to turn the page. However, under this interface, lines 1 through 4 are used to turn a page forward or backward and line 5 is used to turn to the first or last page.

As shown in FIG. 17, the second setting is to slide from left to right in the interface of Chinese vowels, which means that the last clicked initial is cancelled and the interface of the initial is returned to.

3.4 problems that can be encountered with respect to input:

when the user clicks the initial consonant key and the final consonant key, the system will compose the 'tone' and display it on the top most position in the form of Chinese character. If a plurality of tones exist, only the front tone is input in a sliding mode, and the back tone follows the back tone and is displayed in a Chinese character form.

The following are two examples of the invention:

(1) inputting: wojianhuiwanyidianshuijiao

The top most front bit may show "i will sleep a little later today", at this time if the "me" word is input by coasting, the following input jianhuiwanyidianhuijiao still exists in the background, and the top most front bit may become "will sleep a little later today". Then, "today" is input again, and huiwanyidianshuijiao still exists in the background, and the top most digit may be displayed as "sleep a little bit back", and so on until the jiao sound is recognized.

If before the Chinese character corresponding to the last sound is not input, the input of more sounds by clicking the initial key and the final key only increases the length of the top most digit. For example, after inputting "me", the top most bit shows that b and a are input when "will go to sleep a little later today". The combined ba tone is connected to jinianhuiwanyidianshuijiao to become jinianhuiwanyidianshuijiaoba, and the foremost position may show "the bar will sleep a bit late today".

(2) The recognition accuracy of the input method may be higher as long sentences are input. However, when a long sentence is input, the recognized content does not match the content that the user wants to input. When the input is: in the case of gezhouxuanjueyingjuouyuagaizhouzuizhouizhouizhouizhouizhouizhiuyuyuyuandexanjurzige,

ideally, the top most display is as shown in fig. 18.

At this time, pressing any one of [ B sound key ], [ C sound key ], [ ch sound key ], [ D sound key ], [ G sound key ], [ H sound key ], [ J sound key ], [ K sound key ], and [ L sound key ] slides upward, so as to input "each state voter should have the qualification required by the voter at the hospital with the largest number of people in the state conference".

But it is also possible to encounter the situation as shown in fig. 19:

at this time, the user can press the [ M sound key ] to slide upwards to input "states", and the sounds the system needs to recognize will become:

xuanjurenyingjuyougaizhouzhouyihuizhongrenshuzuiduozhiyiyuandexuanjurzige

then, the words "voter", "should", "have", "the state", etc. are continuously input.

When the words are not in the word stock, the words can be input respectively. For example, the thesaurus does not have the word "state party", and the user can input "state" first and then "party", and so on to finish the whole sentence.

If an input error is encountered, the [ delete key ] can be clicked to delete the last tone in the initial state of the non-Chinese initial interface.

3.5, the initial state of the Chinese initial interface:

in the initial state of the Chinese initial interface, when the initial key and the final key are not clicked or after the initial key and the final key are input through sliding, the upper word position and the lower word position on each key of the initial key area can display words or single words with higher use frequency at the moment, and can also display self-defined words or single words.

As shown in FIG. 20, in the initial state of the interface, the user can slide and input the high frequency or custom words directly from the initial keys.

The user can set the high-frequency words in the function, or the custom words in the function, or the function is closed. If custom words are enabled, the user may define these words in "function". The user can also set the appearance of the initial state in the "function", such as setting different key colors or skins, etc., and the color of the initial key is slightly darker in fig. 20, and this setting can prompt the user that this is the "initial state".

3.6, relating to the interface of Chinese vowels.

As shown in FIG. 21, these vowel keys represent the respective vowels.

The Chinese vowel interface has the following five characteristics:

(1) the initial is associated. Not any vowel can be combined with a given initial spelling, such as: f can be combined with a, u, ang, but not with e, ai, ing. Since some vowels cannot be combined with their spellings after a certain initial is determined, the vowel key representing it is also unusable. The rhyme name on the unavailable rhyme key can not be displayed or can be displayed in light color and other characteristic representations which cannot be clicked.

(2) The last 3 vowel keys in row 5 each represent two vowels.

(3) in the schematic diagram of the present specification, v represents u, ue represents u, ü and ü simultaneously represent ü and ü an. but the user can set the representation of these original sounds in the "function" of the scheme.

(4) in order to take care of the habit of many people who write everyday, u and v both represent vowels ü after clicking J, Q, X, Y in the schematic diagram of the present specification.

(5) And a mark is arranged on the last key of the Chinese vowel interface triggered by the [ M initial consonant key ], namely the [ ui & v vowel key ], and is used for marking that the 'initial consonant M' is not spelled with any vowel. Clicking on this flag may type: wu, and mu three characters.

Correspondingly triggering 24 initial consonant keys entering a Chinese vowel interface, there are 24 different situations that whether each vowel key can be clicked, as shown in fig. 22-29, a dark color vowel represents that the key can be clicked, and a light color vowel represents that the key cannot be clicked.

3.7, inputting the condition that the initial interface and the final interface are switched with each other:

the following is an example of an input "shouji" of the present invention:

the initial state of the Chinese initial interface is shown in FIG. 30.

and secondly, after the user clicks the [ sh initial consonant key ], a Chinese vowel interface triggered by the key appears, the vowel which can be spelled with the initial consonant in sh is displayed in black, and the vowel which cannot be spelled with the initial consonant in sh is displayed in gray.

and thirdly, clicking [ ou rhyme keys ] again and returning to a Chinese initial interface, wherein the upper word position and the lower word position display the Chinese characters corresponding to the shou sound at the time, the difference is that the upper word position is only arranged by the word frequency, and the lower word position is respectively arranged by 4 tones and then is arranged according to the word frequency, as shown in figure 32.

and fourthly, then clicking the J key and switching back to the interface of the Chinese vowels, but the interface is different from the interface triggered by the sh initial consonant key, because the interface is the interface of the Chinese vowels triggered by the J key, the sound of the first character of all the words displayed in the interface is shou, the initial consonant of the second character is J, but the vowel of the second character is indefinite, as shown in the figure 33.

finally point [ i rhyme key ], and finally return to the Chinese initial interface, as shown in fig. 34.

In this case, the Chinese initial interface displays all the words corresponding to two shouji tones in the upper part of the word, but the number of the words is 11 in total, so that only the characters corresponding to the shouji tones are listed from the [ N key ].

The words listed in the lower case are the same as the words listed after the previous input of shou, and even if a few more tones are input, the words in the lower case are unchanged.

In the case shown in fig. 34, if the word to be input is "mobile phone", the user only needs to slide up from the [ B sound key ] to input the word.

4. The English input method comprises the following steps:

both English interfaces have two key areas, which are respectively: the alphabetic keypad and other english keypads, taking the english lower case interface as an example, are specifically partitioned as shown in fig. 35:

the alphabetic keypad includes the top 4 rows and the bottom 3 rd and 4 th keys of the interface, and all the keys of the keypad are letter keys which represent the letters of the respective key names.

The 1 st row of letter keys are sequentially as follows from left to right: a [ b bond ], [ c bond ], [ a bond ], [ d bond ], [ f bond ], [ g bond ];

the 2 nd row letter keys are sequentially as follows from left to right: a [ h bond ], [ j bond ], [ k bond ], [ l bond ], [ m bond ], [ n bond ];

the 3 rd row letter keys are sequentially as follows from left to right: a [ p bond ], [ q bond ], [ r bond ], [ s bond ], [ e bond ], [ t bond ];

the 4 th row of letter keys are sequentially as follows from left to right: [ w bond ], [ x bond ], [ y bond ], [ z bond ], [ i bond ], [ o bond ];

the 5 th row of letter keys are sequentially as follows from left to right: [ u bond ], [ v bond ].

The 7-7-6-6 format from the "songs by letters" is so arranged that:

ＡＢＣＤＥＦＧ

ＨＩＪＫＬＭＮ

ＯＰＱＲＳＴ

ＵＶＷＸＹＺ

after the arrangement into the format, all the original sound letters and v are extracted to change 7-7-6-6 into 5-6-5-4, and finally the extracted 6 letters are plugged back according to different orders to adapt to the 5-row and 6-column keyboard of the virtual keyboard.

Since letter songs are well known, such an arrangement gives a feeling of great acquaintance to most users.

The scheme sets the [ a key ], [ e key ], [ i key ], [ o key ], [ u key ], [ v key ] to have different appearances (such as different colors) from other 20 [ letter keys ], so that the scheme can play two roles:

(1) prompting the user that the current interface is an English interface (an English lowercase interface or an English uppercase interface), and the input state is an English input state;

(2) the user can conveniently and quickly find the 6 letters which are not arranged according to the alphabet sequence and the alphabet song format.

Under the English capital interface, pressing the letter key can input English capital letters, sliding upwards from the letter key can input English lowercase letters, sliding downwards from the letter key can input symbols, and the [ U key ] and the [ V key ] are used as exceptions.

As shown in fig. 36 and 37, the front and rear are the english lowercase interface and the english uppercase interface, respectively.

5. The symbol input method comprises the following steps:

there are three key areas under the symbol interface, which are: class group keypad, symbol keypad, other keypads in general, and the specific distinction is shown in fig. 38:

the keys in the symbol keypad are symbol keys and clicking on a symbol key can input a symbol.

The symbol keypad is horizontally slid to turn pages to display more symbols, the leftward sliding is to turn pages backward, and the rightward sliding is to turn pages forward.

When the page needs to be turned backwards, the page 1 can be turned backwards by sliding from right to left in the 1 st to 3 rd rows of the symbol keypad; sliding from right to left in row 4 may flip to the last page as shown in FIG. 39.

When the page needs to be turned forward, the page 1 can be turned forward by sliding from left to right in the 1 st to 3 rd rows of the symbol keypad; scrolling from left to right in row 4 may flip to the first page as shown in FIG. 40.

The keys in the class group keypad are class group keys. Clicking or swiping from the class group key may switch different classes and groups.

In the scheme, the symbols are divided into 4 groups, each class is 4, and 16 classes are total, specifically as follows:

The class group key has a class name bit and a group number bit. The number on the class name bit represents the class number of the group, such as "2-4" represents the

group

2, 4, and the Chinese character is the abbreviation of the class name, such as "winning" represents the Chinese punctuation.

As shown in fig. 41, is a single class group key example.

The characters of the group number positions on the 4 class group keys are all from top to bottom: group 1, group 2, group 3, group 4, which represent group 1, group 2, group 3, group 4, respectively.

As shown in fig. 42, the key is a class group key of all 4 groups and 16 classes, and clicking the class group key can switch the symbol keypad to the class corresponding to the class name abbreviation at the name position of the key; sliding up from the class group key can switch the class group key region to the group corresponding to the group number on the key group number position.

The following is an embodiment of the symbol interface switching and page turning of the present invention:

after entering, the default is the 1 st group of the 1 st class, namely the Chinese punctuation class, as shown in FIG. 43.

and the 3 rd group key, namely the 1-3 radical key of the upper graph slides upwards, the group is switched to the 3 rd group, and the default is switched to the 3 rd group, namely the 1 st class, namely the pinyin symbol class, as shown in FIG. 44.

page turning, the page turning can be performed by sliding from right to left in the 1 st to 3 rd rows of the symbol keypad as shown in fig. 45.

and switching class, clicking the 2 nd class group key, namely the 3-2 ZhuYin key in figure 45, and switching to the group of 2 nd class, namely the ZhuYin symbol class, as shown in figure 46.

6. Number symbol (numeric and mathematical symbol) input method:

as shown in fig. 47, the numeric character interface is shown, and the numeric character keypad is shown on the top 4 of the numeric character interface, and includes 10 numeric keys and 14 symbolic keys, and the numeric keys and the symbolic keys are distinguished by different colors or skins for the user, and can be easily seen by the user at first sight.

Clicking any key of the numeric keypad can input corresponding numbers or symbols, sliding upwards or downwards from the numeric keys or the symbol keys, and inputting more symbols.

The invention has the following advantages:

although the scheme has a plurality of interfaces, all the interfaces use the same virtual keyboard layout with 5 rows and 6 columns, and a user can find the clicking or sliding position according to the habit after being familiar with the virtual keyboard. Thus, part of the burden of the eyes of the user can be relieved, and the comfort level of the user in use is further improved.

Each key on the virtual keyboard is larger than that of the PC type virtual keyboard, and is not easy to be wrongly clicked; the meaning of clicking each key is single, and the input is more accurate than that of a T9 keyboard.

And thirdly, in the symbol interface, the classes and the groups can be switched by clicking and sliding on the class group key area, and pages can be turned in a transverse sliding mode, so that a user can find the symbols desired by the user in the shortest time.

And (IV) the letter arrangement modes of the English interface and the Chinese initial interface are from the 4-line arrangement mode of 'letter song' which can be detailed in ear, so that a user can feel like great acquaintance and can quickly know the virtual keyboard.

(V) the use of different appearances for vowels and v on the two English interfaces gives the user a double cue, namely: 1. now the English interface; 2. these differently appearing virtual keys represent the vowel or letter v to help the user find quickly.

And (VI) a large number of punctuations are arranged on the interfaces of the two English languages, the punctuations can be input only by sliding downwards in the 1 st row to the 4 th row without switching to a symbol interface.

And (VII) in the English lowercase interface, capital letters can be input in an upward sliding mode without assistance of a shift key and the like, and the thinking continuity of a user is not influenced.

(eight) each vowel under the Chinese vowel interface has its own fixed position, and these vowels are arranged according to the law, and the user can find the required vowel and become familiar with these arrangement modes quickly as long as know the law.

the method is different from the traditional double spelling, the traditional double spelling represents a plurality of meanings by one key, the user needs to remember the hard back, the scheme directly switches and displays the vowels after clicking the initial consonants, the user knows which key to click at one glance, the user can learn while using, the layout and the positions of the keys are fixed, and the user does not need to see by eyes after proficiency, in addition, the traditional double spelling input method uses 26 to 27 keys to represent 33 vowels, so that the user needs to represent two vowels by 5 keys, and the scheme has 30 virtual keys, the number of the keys representing two vowels is reduced to 3, even if the 3 keys are very similar to one another, the user can easily recognize the adjacent vowels and the ui according to the characteristics of the sound of the two keys, particularly, the sound of the adjacent region and the ui and the sound of the user, and the sound of the user can be recognized in a very similar area by the user according to the sound of the adjacent region and the adjacent region of the sound of the user.

And (ten) when inputting Chinese, selecting characters, words and sentences by sliding, and fully utilizing the space of the virtual keyboard to display the words and phrases. By utilizing the upper word position and the lower word position, 24 double-word words and 24 single words can be displayed at most, and 48 optional items are provided in total, so that the user can complete the input under the condition of less page turning or even no page turning as much as possible.

And eleventh, when inputting Chinese, page turning is carried out by adopting longitudinal sliding to display alternative words, and the operable area accounts for 80 percent (4 lines in 5 lines) or even 100 percent (under a Chinese vowel interface, a function needs to be set) of the whole virtual keyboard area. Other input methods applied to touch screens turn pages by clicking or sliding, have a small operable area (generally less than 20% of the area of the virtual keyboard), and are therefore inconvenient to use. In addition, when pages are turned, the user can turn to the first page or the last page by longitudinally sliding in a specific area (generally, the 4 th or 5 th row), and when the user thinks that the words to be input are uncommon, the user can directly turn to the last page and then turn forward to search the words desired by the user.

The 'spelling column' is established on the 'word selection column' when Chinese is input by many input methods, because users of other input methods may input incomplete sounds, such as sounds with only initial consonants. However, the mode of 'two-key sound combination' in the scheme ensures that all the sounds are complete sounds, and the key points of 'note splitting' is required even if the 'consonant-free' sound is input, so that a 'Pinyin column' is not required, the screen space is reduced, and the complete sound is directly corresponding to the top position of the Chinese character.

And (thirteen) the initial state of the Chinese initial interface can be set, and some common words can be input by sliding directly without typing.

under the Chinese initial interface, the upper word position and the lower word position can display more candidate words by turning pages, and the page turning is realized by transverse sliding; the page can be turned to the last page by sliding from the right to the left in the 1 st to the 3 rd rows and from the right to the left in the 4 th row; the page can be turned to the front by sliding from left to right in the 1 st to the 3 rd lines, and can be turned to the first page by sliding from left to right in the 4 th line; under the 'Chinese vowel interface', the horizontal sliding can be used for turning pages; the transverse sliding is performed for 1 to 4 rows to turn a page forwards or backwards, and the transverse sliding is performed for 5 th row to turn the page to the first page or the last page;

(1.8) the input mode of the blank, comma and period is as follows: clicking a deleting key, a space key and an enter key in other general key areas to respectively delete, input a space and carry out; sliding upwards from the [ character boundary key ] can input commas, and sliding upwards from the [ English boundary key ] can input periods;

(1.9) clicking [ sign interface key ] on the 'general other key area' can be switched to 'sign interface'; clicking the English interface can switch to the English interface; clicking the middle limit key can switch to the Chinese initial interface; sliding up from [ middle key ] can switch to "number symbol interface"; when the interface is switched to other interfaces during the 'Chinese vowel interface', the interface is switched back to the 'Chinese initial interface'; similarly, switching from other interfaces to the "Chinese vowel interface" needs to go through the "Chinese initial interface".

2. An input method based on a touch screen is characterized by comprising a virtual keyboard with a rectangular interface; the arrangement mode is 5 rows and 6 columns, 30 rectangular units are arranged, and each rectangular unit forms a virtual key; the state that the virtual keyboard can input English is an English interface; the user performs interaction such as clicking (pressing and releasing) or sliding (moving and releasing after pressing) with the virtual keyboard to complete input, wherein the sliding mode comprises longitudinal sliding and transverse line sliding;

(2.1) "English interface" includes English lowercase interface and English capitalization interface, and the initial interface of English interface is English lowercase interface, two English interfaces have alphabetic keypad and other English keypads;

(2.2) "English interface" the first 4 rows and the 3 rd and 4 th keys of the 5 th row form an "alphabetic keypad", and the alphabetic keys "represent the letters of the respective key names;

the term "letter bond" specifically includes

Row 1, from left to right, is: a [ b bond ], [ c bond ], [ a bond ], [ d bond ], [ f bond ], [ g bond ];

row 2, from left to right, is: a [ h bond ], [ j bond ], [ k bond ], [ l bond ], [ m bond ], [ n bond ];

row 3, from left to right, is: a [ p bond ], [ q bond ], [ r bond ], [ s bond ], [ e bond ], [ t bond ];

row 4, from left to right, is: [ w bond ], [ x bond ], [ y bond ], [ z bond ], [ i bond ], [ o bond ];

row 5, from left to right, is: [ u bond ], [ v bond ];

(2.3) under the English lowercase interface and the English uppercase interface, the 1 st, the 2 nd, the 5 th and the 6 th keys on the 5 th row form an English other key area which is used as 1 switching key and 3 editing keys; a mark is arranged on the upper side of the space key of the keypad, the upper case ↓isdisplayed on an English lower case interface, and the lower case ↓isdisplayed on the English lower case interface;

(2.4) English input mode is that under the English lowercase interface, the English lowercase letters can be input by clicking the letter key, English uppercase letters can be input by sliding upwards from the letter key, and symbols can be input by sliding downwards from the letter key except the [ u key ] and the [ v key ]; under the English capital interface, the English capital letters can be input by clicking the letter key, the English lowercase letters can be input by sliding upwards from the letter key, and the symbols can be input by sliding downwards from the letter key except the U key and the V key;

(2.5) clicking the middle-range key in the English other key area can be switched to a Chinese initial interface; sliding up from [ middle key ] can switch to "number symbol interface"; in the case of an English interface, switching to a symbol interface must be realized through a Chinese initial consonant interface, a symbol interface or a number-symbol interface, so that a general other keypad appears below the interface; the space bar slides upwards, so that the switching between an English lowercase interface and an English uppercase interface can be realized.

3. An input method based on a touch screen is characterized by comprising a virtual keyboard with a rectangular interface; the arrangement mode is 5 rows and 6 columns, 30 rectangular units are arranged, and each rectangular unit forms a virtual key; the state in which the virtual keyboard can input symbols is a "symbol interface"; the user performs interaction such as clicking (pressing and releasing) or sliding (moving and releasing after pressing) with the virtual keyboard to complete input, wherein the sliding mode comprises longitudinal sliding and transverse line sliding;

(3.1) "symbol interface" includes three keypads of "group keypad", "symbol keypad" and "general other keypad";

(3.2) the key in the 'symbol keypad' is a 'symbol key', pages can be turned to display more symbols by sliding in the 'symbol keypad' transversely, pages are turned backwards by sliding to the left, and pages are turned forwards by sliding to the right; when the page needs to be turned backwards, the page 1 can be turned backwards by sliding from right to left in the 1 st to 3 rd rows of the symbol keypad; the page can be turned to the last page by sliding from right to left in the 4 th line; when the page needs to be turned forward, the page 1 can be turned forward by sliding from left to right in the 1 st to 3 rd rows of the symbol keypad; the page can be turned to the first page by sliding from left to right in the 4 th row;

(3.3) the keys in the "class group keypad" are "class group keys", clicking or sliding from "class group key" can switch different classes and groups:

the symbols are divided into 4 groups of 4 classes each, for a total of 16 classes, as shown in detail below —

group 4 includes: japanese hiragana, Japanese katakana, Russian letters, Greek letters;

the ' class group key ' has a ' class name bit ' and a ' group number bit ', the number on the class name bit ' represents the class number of the group, for example, ' 2-4 ' represents the class 4 of the group 2, and the Chinese character is short for the class name, for example, ' winning symbol ' represents Chinese punctuation; the characters of 4 'class keys' upper 'group number bits' are all from top to bottom: 1, 2, 3, 4, each of which represents group 1, 2, 3, 4;

(3.4) the symbol input is that the symbol can be input by clicking the 'symbol key' under the 'symbol interface';

(3.5) clicking the 'class group key' can switch the 'symbol key zone' to the corresponding class of the 'class name position' of the key; the upward sliding from the class group key can switch the class group key area to the group corresponding to the group number on the key 'group number position';

(3.6) clicking the [ English boundary key ] on the 'general other key area' can be switched to the 'English interface'; clicking the middle limit key can switch to the Chinese initial interface; sliding up from the middle key can switch to the number symbol interface.
