Description

Character entry apparatus and characters input method

Technical field

The present invention relates to character input field, especially a kind of being applied to has character entry apparatus on the electronic equipment of touch-screen and characters input method.

Background technology

Computer equipment is provided with keyboard mostly as character input device, existing keyboard is qwerty keyboard mostly, keyboard is provided with button corresponding to 26 English alphabets, and be provided with button corresponding to 10 numerals, when user needs input alphabet or numeral, only need by next corresponding button.When using physical keyboard input Chinese character, being by encoding to Chinese character, utilizing English alphabet character or numerical character sequence to represent a Chinese character.

For the portable electric appts such as panel computer, mobile phone, the physical keyboard arranging qwerty keyboard becomes unrealistic: or cause the volume of electronic equipment larger, affect the portability of electronic equipment, or each button of keyboard is arranged very little, be unfavorable for that user pushes button.Therefore, existing a lot of electronic equipment all arranges touch-screen, and the button of generating virtual on the touchscreen, thus facilitate user to push button when not increasing electronic equipment volume.

But, because the touch-screen area of existing portable electric appts is little, if the dummy keyboard generated is the full keyboard with 26 corresponding buttons of letter, then or to occupy the area of touch-screen excessive, be unfavorable for showing other information on the touchscreen, each virtual key area is too little, is unfavorable for that user clicks.Therefore, the dummy keyboard that existing electronic equipment shows on the touchscreen is nine grids keyboard mostly, and it has 12 virtual keys, corresponds respectively to 10 numerical characters and two conventional special symbols: " * " and " # ".

Although nine grids keyboard can inputting digital character easily, nine grids input through keyboard English alphabet is used then extremely to bother.Because the virtual key of nine grids keyboard does not form relation one to one with alphabetic character, each virtual key needs are multiplexing could input 26 English alphabets, when therefore needing to input some English alphabet, need repeatedly to click same virtual key, cause the input speed of character slow.

If use nine grids keyboard to input Chinese character by stroke mode, normally five of nine grids virtual keys are configured to correspond to horizontal, vertical, left, flick, folding five kinds of strokes.During input Chinese character, user clicks corresponding virtual key successively according to the stroke order of Chinese character, and the electronic equipment such as panel computer, mobile phone shows corresponding candidate word on the touchscreen.But, when the Chinese-character stroke inputted is more, needs the virtual key number of times of click more, also affect the input speed of Chinese character.In addition, the key arrangement of existing nine grids keyboard is form, needs constantly moveable finger rapidly during input character, once finger shift position is incorrect, the easy virtual key clicking mistake, is unfavorable for that user carries out touch system, also affects the input speed of Chinese character.

In addition, handwriting pad input character supported by more existing electronic equipment, and then this not only increases cost, the volume of electronic equipment, and the discrimination of existing handwriting input software to character is lower, and character recognition overlong time, affect character input speed.

Publication number is the innovation and creation that the Chinese invention patent application of CN1560723A discloses a kind of " five-finger key input method " by name, this input method arranges five physical buttons on the electronic equipments such as mobile phone, and five physical buttons are arranged on the side of electronic equipment fuselage.Each in five physical buttons is configured to correspond to four numerical characters or English alphabet character or special symbol character by this input method, during each input character, all need to press a corresponding physical button, display screen display four corresponding candidate characters.Then selecting four candidate characters, is realized by the pressing operation of other four buttons to the selection of candidate characters.

But this input method all needs pressing twice physical button to the input of arbitrary character, namely there is the process selecting character, cause character to input speed very slow.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of character entry apparatus improving character input speed.

Another object of the present invention is to provide a kind of character entry apparatus being conducive to user's touch system.

Another object of the present invention is to provide a kind ofly has the characters input method of electronic equipment inputing characters of touch-screen rapidly.

In order to realize above-mentioned fundamental purpose, character entry apparatus provided by the invention has the virtual key generation module for generating multiple virtual key, for detecting the whether clicked button detection module of virtual key, button detection module generates input signal when virtual key is clicked, wherein, virtual key comprises five or ten character keys, character entry apparatus also comprises character and searches module, in character database, corresponding character is searched according to input signal, character corresponding when the character keys that character database stores corresponding character when a character keys is clicked separately and more than two is clicked simultaneously, and the Charactes Display module of character that module finds or candidate characters searched in display character.

From such scheme, because character database does not singly store character corresponding when a character keys is clicked separately, also storing more than two character keys by clicking simultaneously is corresponding character, and namely user can click multiple character keys and input character simultaneously.Quantity due to character keys is five or ten, therefore by after carrying out binary coding to character keys, remove the situation that all character keys are all not clicked, by acquisition 31 kinds or 1023 different codings, namely one have 31 kinds or 1023 kinds of different input modes, the input of 10 numerical characters and 26 English alphabet characters can be met.Like this, any one numerical character or alphabetic character can be realized by click character keys, and certainly, one click can click multiple virtual key simultaneously.Visible, not needing when input character, by repeatedly clicking same character keys, not select the process of character yet, greatly can improve the input speed of character like this.

In addition, the quantity of character keys is five or ten, finger quantity that is singlehanded with human body or both hands is equal, guarantee that each finger is only for clicking a character keys, without the need to moveable finger during input character, only finger lifted or put down, while improving character input speed, greatly reducing the probability that character keys mistake is clicked, be conducive to user and carry out touch system input.

A preferred scheme is, the input signal that button detection module generates comprises the coded signal of encoding to character keys, and character database stores unique digitally encoded signal corresponding to each numerical character under number entry mode and each alphabetic character is corresponding under alphabetic entry mode unique alphabetic coding signal.

As can be seen here, because each numerical character and alphabetic character all have unique coded signal, can guarantee that numerical character and alphabetic character are inputted by one click character keys like this, improve the input speed of character.

Further scheme is, the character key arrangement that virtual key generation module generates becomes meniscus shaped.Finger tip due to human finger five fingers under natural relaxation state is meniscus shaped distribution, therefore character key arrangement is become meniscus shaped, and the finger tip being conducive to five fingers clicks character keys, the quick input character of person easy to use.

For realizing another above-mentioned object, characters input method provided by the invention comprises virtual key generation step: generate multiple virtual key on the touchscreen; Button detecting step: whether clickedly detect virtual key, and the clicked rear generation input signal of virtual key detected; Wherein, the virtual key generated in virtual key generation step comprises five or ten character keys; The method also comprises character finding step: in character database, search corresponding character according to input signal, character corresponding when the character keys that character database stores corresponding character when a character keys is clicked separately and more than two is clicked simultaneously; Charactes Display step: the character found in display character finding step or candidate characters.

From such scheme, user is by the one or more character keys of one click, all can input character, after binary coding is carried out to five or ten character keys, remove the situation that all character keys are all not clicked, 31 kinds or 1023 kinds of different input modes can be obtained, the input of 10 numerical characters and 26 English alphabet characters can be met, namely can guarantee that each numerical character or English alphabet character are realized by one click character keys under number entry mode or under alphabetic entry mode, thus improve the input speed of character.

A preferred scheme is, before generating virtual button, Chinese character separating is become more than one radical, form the radical sequence of each Chinese character, to each radical by horizontal, perpendicular, skim, right-falling stroke, roll over five kinds of strokes and carry out stroke coding, after generating character keys, in character keys five are configured to respectively correspond to horizontal stroke, perpendicular, skim, right-falling stroke, roll in five kinds of strokes, the root coding signal of character keys corresponding to each radical is generated according to the stroke coding of each radical, and store the root coding signal that in radical sequence corresponding to each Chinese character under Chinese character root input pattern, each radical is corresponding in character database.

As can be seen here, during with radical input pattern input Chinese character, once can input multiple strokes of radical, reduce stroke input number of times, improve the input speed of Chinese character.

Further scheme is, when carrying out stroke coding to radical, is merged by the identical stroke of same radical.

Visible, the identical stroke of same radical is merged, the stroke quantity of the required input of same radical can be reduced, the input speed of Chinese character can be improved further.

Embodiment

Character entry apparatus of the present invention is arranged on to be had on the electronic equipment of touch-screen, carries out character input for generating virtual keyboard on the touchscreen by user.Characters input method of the present invention a kind ofly allows user in the method for the electronic equipment inputing characters with touch-screen.The character of indication of the present invention comprises " 0 " to " 9 " ten numerical characters, 26 English alphabet characters, Chinese character and special characters, wherein Chinese character is the Chinese character specified in standard GB/T K and GB18030, and special character comprises the characters such as punctuation mark.

Character entry apparatus first embodiment:

See Fig. 1, the present embodiment has virtual key generation module 11, module 14 and Charactes Display module 15 searched in button detection module 12, character database 13, character.

Button generation module 11 is for generating virtual keyboard on the touchscreen, as shown in Figure 2, the dummy keyboard that the touch-screen 20 of electronic equipment generates comprises eight virtual keys, and wherein five is character keys, be K1, K2, K3, K4, K5 respectively, also having three is function button C1, C2, C3.When character keys as referred to herein refers to and is clicked separately or clicked with other character keys simultaneously, the button of a character can be generated by character entry apparatus, and function button can not generate a character after being clicked separately, be only change the character input system of character entry apparatus or change the function of character keys.

Under state shown in Fig. 2, touch-screen 20 is longitudinally arrange, and dummy keyboard is positioned at the bottom of touch-screen 20, and five character keys K1, K2, K3, K4, K5 are arranged in meniscus shaped, and three function buttons C1, C2, C3 are positioned at the upper left corner of dummy keyboard.Five character keys K1, K2, K3, K4, K5 are arranged in meniscus shaped, are clicks for the convenience of the users.Because the hand of human body is under natural relaxation state, the finger tip of five fingers is meniscus shaped distribution, five character keys is arranged to meniscus shaped, can person easy to use be placed on a virtual key by each finger tip, thus person easy to use clicks virtual key.

Such as, distribute five virtual keys K1, K2, K3, K4, K5 the thumb, forefinger, middle finger, the third finger and the little finger of toe that are configured to correspond to the right hand, such user when input character without the need to moveable finger, only need finger to be lifted or put down the operation that can realize clicking character keys, while raising character keys click speed, also avoid character keys to be clicked by mistake, be conducive to user and carry out touch system input.

Three function buttons are respectively used to realize specific function, such as function button C1 is for realizing the switching of English input mode and input in Chinese pattern, function button C2 is for realizing the switching of number entry mode and other input patterns, and function button C3 is for realizing the switching that capitalization input inputs with lowercase under English input mode.

Certainly, on dummy keyboard, the distribution of multiple virtual key can have multitude of different ways, as shown in Figure 3, touch-screen 20 horizontally set, dummy keyboard is positioned at the bottom of touch-screen 20, five character keys K1, K2, K3, K4, K5 are arranged in meniscus shaped, and three function buttons C1, C2, C3 are also the upper left corner being positioned at dummy keyboard, but are laterally arranged in order.

Button detection module 12 detects for carrying out click to multiple virtual key, has judged whether that virtual key is clicked, generates input signal, and the input signal of generation is outputted to character search module 14 when judging have virtual key clicked.

When any one character keys is clicked, button detection module 12 generates the binary coded signal to five character keys, and clicked character keys uses binary number " 1 " mark, and not clicked character keys uses binary number " 0 " mark.Such as, when character keys K1 is clicked separately, what generate is 00001 to the coded signal of five character keys K5, K4, K3, K2, K1, if when character keys K2 is clicked separately, the coded signal generated is 00010, time clicked while of character keys K1, K2, the coded signal of generation is 00011, so analogizes.

Quantity due to character keys is five, can generate altogether 31 different efficient coding signals, can meet the input needs of ten numerical characters or 26 English alphabet characters after therefore carrying out binary coding to character keys.Namely under number entry mode, just can input a numerical character by the one or more character keys of one click, under alphabetic entry mode, by the one or more character keys of one click, also can input an English alphabet character.Greatly can facilitate the input of numerical character and English alphabet character like this, improve the input speed of character.

When function button is clicked, button detection module 12 also can generate input signal, and now input signal is not the binary coded signal of character keys, but the signal of corresponding function button.Character is searched after module 14 receives the clicked input signal of function button, automatically switches to relevant input pattern.

The present embodiment can support multiple input pattern, comprises number entry mode, English alphabet input mode and Chinese-character stroke input pattern etc.Correspondingly, in character database 13, multiple subdata base is set: numeric character data storehouse, alphabetic character database, Chinese character database, stores the corresponding relation between character and the coded signal of character keys under multiple different input pattern respectively.

Such as, under being set in numerical character input pattern, corresponding inputting digital character " 1 " when character keys K1 is clicked separately, corresponding inputting digital character " 2 " when character keys K2 is clicked separately, when character keys K1, K2 are clicked simultaneously, corresponding inputting digital character " 3 " etc., so analogize.

In numeric character data storehouse, store the digitally encoded signal of numerical character " 1 " and its correspondence for " 00001 ", the digitally encoded signal of numerical character " 2 " and its correspondence is " 00010 ", the digitally encoded signal of numerical character " 3 " and its correspondence is " 00011 ", so analogizes.Like this, when character searches input signal that module 14 receives for " 00011 ", under number entry mode, in numeric character data storehouse, corresponding numerical character is found for " 3 ".

Certainly, can input quickly and accurately in order to ensure numerical character, the digitally encoded signal that each numerical character is corresponding should be unique.Such as, user clicks character keys K2, K3, K5 under number entry mode simultaneously, the input signal that button detection module 12 generates is " 10110 ", module 14 searched in character cannot search the numerical character of coded signal corresponding to " 10110 " in numeric character data storehouse, then do not export any character.

In the same manner, under alphabetic entry mode, each English alphabet is also uniquely to there being an alphabetic coding signal, and alphabetic coding signal as corresponding in letter " a " is " 00001 ", and the alphabetic coding signal that letter " b " is corresponding is " 00010 ", so analogizes.

In order to programme conveniently, the character keys of low five required clicks when determining to input each letter of the ASCII character binary numeral that English alphabet character can be used corresponding.ASCII character binary numeral is corresponded respectively to character keys K1, K2, K3, K4, K5 from low level to a high position, the alphabetic coding signal obtained is as follows: the alphabetic coding signal that letter " a " is corresponding is " 00001 ", the alphabetic coding signal that letter " b " is corresponding is " 00010 ", the alphabetic coding signal that letter " c " is corresponding is " 00011 ", the alphabetic coding signal that letter " z " is corresponding is " 11010 ", and namely user needs to click character keys K2, K4, K5 ability input alphabet " z " simultaneously.

Character searches module 14 after receiving the clicked input signal of function button, corresponding database can be selected according to clicked function button from multiple subdata base, and from the subdata base of correspondence, search corresponding character after receiving the coded signal of character keys.

Character is searched numerical character or English alphabet Charactes Display that module 14 finds on touch-screen 20 by Charactes Display module 15.

Character machining module 12 is that therefore user is without the need to being placed on multiple character keys simultaneously by finger, only needs to lift from multiple character keys simultaneously at the coded signal of the moment generation character keys that all fingers lift.Such as, user needs input numeral " 9 ", character keys K1, K4 should be clicked simultaneously, now user can first click character keys K1, before thumb does not lift, nameless click character keys K4, then lifts thumb with nameless simultaneously, then character machining module 12 lifts moment generation input signal according to all fingers, and coded signal is " 01001 ".Therefore, difference finger can successively be placed on different character keys by user, and this does not affect the work of character entry apparatus.

Meanwhile, before user lifts all fingers, can revise arbitrarily the character keys of click, such as user has clicked character keys K1, K4, but finds to click mistake, should need to click character keys K1, K5.Now, user when not lifting thumb, can lift the third finger, and is placed on by little finger of toe on character keys K5, then lifts thumb and little finger of toe simultaneously.Character machining module 12 only can generate all fingers and lift moment generation input signal, and the input signal namely generated is " 10001 ".

In addition, character keys K1, K2, K3, K4, K5 position on touch-screen 20 can dynamic conditioning, and virtual key generation module 11 dynamically can adjust the position of each virtual key K1, K2, K3, K4, K5 according to the hobby of user.After user clicks a certain character keys, and drag this character keys when sliding, character keys can follow finger sliding, and rests on the position that finger stops.In addition, virtual character generation module 11 remembers the position that this character keys stops, and when next generating virtual button, this character keys is created on specific position.

Certainly, virtual key generation module 11 can also add up the position that user clicks character keys, after removing the larger a few locations of deviation, gets the reposition of the higher position of click frequency as this character keys, realizes the position dynamic conditioning to character keys.

Be described above the input of numerical character and English alphabet character, introduce the input of Chinese character below.

Input Chinese character can use Pinyin Input pattern, stroke entry mode, five input patterns or radical input pattern, Pinyin Input pattern and five input patterns are all based on inputting English letter character, just need further to encode to inputted English alphabet character after the corresponding English alphabet character of input, word selection, be all known technology to the coding of alphabetic character, word selection under Pinyin Input pattern or five input patterns, no longer launch explanation herein.

Radical input pattern is that Chinese character separating is become more than one radical, forms radical sequence, and splits by horizontal, vertical, left, flick, folding five kinds of strokes each radical, encode, and carries out the pattern inputted when user inputs Chinese character by radical.

For simple Chinese character, whole Chinese character can be inputted as a radical, for the Chinese character of complexity, first Chinese character separating can be become the radical of more than two, form radical sequence, then stroke coding is carried out to each radical.Such as, for simple Chinese character " soil ", it as a radical, can carry out stroke coding by " horizontal, vertical, horizontal ".For complicated Chinese character " Chinese ", after resolving into two radicals " Rui " and " again ", respectively stroke coding is carried out to two radicals.The stroke coding of radical " Rui " is " point, point, horizontal stroke ", and the stroke coding of radical " again " is " folding, right-falling stroke ".

When stroke coding is carried out to radical, namely a radical can be inputted for convenience of user's one click character keys, the multiple identical stroke of same radical is needed to merge, stroke coding as " soil " word is " horizontal, vertical, horizontal ", two " horizontal stroke " merged, after merging, the stroke coding of " soil " word is " horizontal, vertical ".And for example, the stroke coding of radical " Rui " is " point, point, horizontal stroke ", and the stroke coding after merging is " point, horizontal stroke ".

Under radical input pattern, need the entering stroke that setting five character keys K1, K2, K3, K4, K5 are corresponding, correspond respectively to five kinds of stroke horizontal, vertical, left, flick, folding as set five character keys K1, K2, K3, K4, K5, each character keys and a kind of stroke form relation one to one.

Then, the coding of character keys of required click when generating this radical of input according to the stroke coding of each radical, as input " soil " word needs to click character keys K1, K2, input radical " Rui " needs click character keys K1, K3.Then, according to the coding of character keys, generate the binary coded signal of five character keys during each radical of input, this coded signal is root coding signal.Root coding signal as " soil " word is " 00011 ", and the root coding signal of radical " Rui " is " 01001 " etc.

In Chinese character database, store the root coding signal of each radical in radical sequence corresponding to each Chinese character, character searches module 14 after the input signal receiving character machining module 12 transmission, searches corresponding Chinese character according to input signal.Such as, the radical sequence of " Chinese " word is " Rui ", " again ", and root coding signal is respectively " 01001 ", " 11000 ", and two root coding signals that " Chinese " word therefore stored in Chinese character database is corresponding are " 01001 ", " 11000 ".

Because different Chinese character may have identical radical sequence, or different radicals may have identical root coding signal, therefore under radical input pattern, character is searched module 14 and is normally found more than one Chinese character, therefore character is searched module 14 and all Chinese characters found all is shown alternatively word, so that user selects by Charactes Display module 15, touch-screen 20.

Such as, user clicks separately character keys K1, and the input signal that character machining module 12 generates is the binary coded signal of character keys, i.e. " 00001 ", represent input " horizontal stroke ", now may represent that user needs to input the Chinese character containing radical " ", " two " or " three ".Character is searched after module 14 searches corresponding Chinese character from character database 13, shows these Chinese characters alternatively character, so that user selects by Charactes Display module 15 on touch-screen 20.

And for example, when user clicks character keys K1, K2 simultaneously, the input signal that character machining module 12 generates is " 00011 ", represent and input " horizontal, vertical " simultaneously, character is searched module 14 and in Chinese character database, is found Chinese character " ten ", " soil " etc. according to input signal, Charactes Display module 15 according to the multiple Chinese characters found, by these Chinese characters alternatively Charactes Display on touch-screen 20.

Certainly, for the ease of the input of Chinese character, can the person of being set using input a radical, what character searched that module 14 receives that input signal finds at every turn is a radical, can accelerate the input speed of Chinese character so at every turn.

Therefore, when user inputs Chinese character " Chinese ", only need to carry out inputting for twice, first time clicks character keys K1, K3 simultaneously, input radical " Rui ", second time clicks character keys K4, K5 simultaneously, input radical " again ", now Charactes Display module 15 Display of Chinese characters " Chinese " and other possible Chinese characters on touch-screen 20, so that user carries out word selection operation.

Stroke entry mode directly Chinese character is carried out stroke coding by horizontal, vertical, left, flick, folding five kinds of strokes to each Chinese character, forms strokes sequence, and user presses the pattern of stroke order input Chinese character.Under stroke entry mode, first need to carry out stroke coding to Chinese character, and five character keys are configured to button corresponding to five kinds of strokes, user clicks a character keys at every turn and inputs a stroke, forms stroke order thus.

Also store the stroke order of each Chinese character under stroke entry mode in Chinese character database, character is searched module 14 and is searched corresponding Chinese character according to the input signal of button detection module 12, and shows possible candidate characters by Charactes Display module 15.

The present embodiment can also input special character, as punctuation mark character etc.Due under number entry mode, also have Multi-encoding signal not used, these can be set to corresponding multiple different special character by the coded signal used.Certainly, also can set up a function button, namely set up a kind of special character input pattern, to facilitate the more special character of input.

In the present embodiment, virtual key generation module 11 generates three function buttons C1, C2, C3, be respectively used to the switching between different input pattern, during practical application, switching between different input pattern not necessarily needs to realize by arranging function button, can by the incompatible realization of particular group of character keys.

Due under number entry mode and alphabetic entry mode, can't occurring that five character keys are by situation about clicking simultaneously, five character keys therefore can being used by the signal clicked as switching input pattern simultaneously.Namely character machining module 12 is once the input signal generated is " 11111 ", and represent the switching carrying out input pattern, multiple input pattern can switch in turn.

Certainly, due to the situation that five character keys may be used under radical input pattern simultaneously clicked, now can set when five character keys that the clicked time exceedes predetermined time simultaneously, as just thought the switching carrying out input pattern after 1 second.Like this can without the need to systematic function button on touch-screen 20.

Characters input method embodiment:

The workflow of character entry apparatus is introduced below in conjunction with Fig. 4.First, character entry apparatus generates multiple virtual key on the touchscreen, and namely perform step S1, multiple virtual key comprises five character keys and three function buttons, and five character keys should be arranged in meniscus shaped.

Then, whether character machining module detects has character clicked, namely performs step S2, and after judgement has character keys clicked, perform step S3, generate input signal, input signal comprises and carries out the coded signal after binary coding to character keys.Then, the input signal of generation is outputted to character and searches module by character machining module, character searches module according to current input pattern, corresponding character is searched in corresponding character database, namely step S4 is performed, judge whether that corresponding character exists simultaneously, namely step S5 is performed, if there is no corresponding character, then do not input any information to Charactes Display module, if find corresponding character, then perform step S6, the character found is exported to Charactes Display module, the character found or candidate characters show on the touchscreen by Charactes Display module.

For numerical character, English alphabet character and the method detailed being inputted Chinese character by phonetic mode, five modes, stroke mode or radical modes, discuss in detail in character entry apparatus first embodiment, do not repeat them here.

Character entry apparatus second embodiment:

The present embodiment also has virtual key generation module, module and Charactes Display module searched in button detection module, character database, character, the present embodiment and character entry apparatus first embodiment unlike, the virtual key that virtual key generation module generates comprises ten character keys.

See Fig. 5, the virtual key that virtual key generation module generates on touch-screen 30 comprises ten character keys K11, K12 ... K20 and three function button C11, C12, C13, wherein five character keys K11, K12 ... K15 corresponds to five fingers of the right hand, and be arranged in meniscus shaped, other five character keys K16, K17 ... K20 corresponds to five fingers of left hand, is also be arranged in meniscus shaped.The function of three function button C11, C12, C13 realizations is identical with the first embodiment, repeats no more.

In the present embodiment, quantity due to character keys is ten, therefore when inputting digital character, can set the one-to-one relationship of each character keys and a numerical character, when so often inputting a numerical character, only need click character keys.When input alphabet, character keys K11, K12 can be set ... K15 correspondence input lowercase, and character keys K16, K17 ... K20 correspondence input capitalization, can avoid the switching of upper and lower case letter input pattern like this, more can improve the input speed of character.

Under radical input pattern, character keys K11, K12 can be set ... K15 is used for input stroke coding, and character keys K16, K17 ... K20 is used for word selection, or setting character keys K11, K12 ... K15 is for inputting the first radical, and character keys K16, K17 ... K20 is for inputting the second radical.

Certainly, because the present embodiment has ten character keys, after carrying out binary coding, there is more kinds of input signal, therefore can input more special character easily, and the input of Chinese character under simplified stroke input pattern.

From such scheme, because user can click multiple character keys simultaneously, therefore, it is possible to the character keys that magnitude setting is less, as five or ten just can input 10 numerical characters or 26 alphabetic characters, user gets final product inputting digital character or alphabetic character by one click operation, and stroke pattern input Chinese character can be quickly move through, significantly improve the input speed of character.

In addition, the quantity of character keys is arranged to one hand or both hands point equal quantity, and character key arrangement is become meniscus shaped, be conducive to user's input character rapidly when not moveable finger, reduce the probability that mistake clicks character keys, and person easy to use clicks character keys under natural relaxation state.

Although the part button of existing physical keyboard has multiplexing function, namely user can input another character corresponding to this character keys by next function button and character keys simultaneously, such as press " Shift " button in qwerty keyboard and character keys " 1 " simultaneously, can input character "! "; but this method only can realize the multiplexing function of single character keys, and user is still need moveable finger pressing function button, therefore must learn the position of each function button in physical keyboard by heart; otherwise easily cause input error, have influence on the input speed of character.

Method of the present invention allows user to click multiple character keys simultaneously, and inputs different characters thus, and user does not substantially need moveable finger in the process of input character, reduces the chance of wrong input character, also improves the input speed of character.

Certainly, above-described embodiment is only the present invention's preferably embodiment, during practical application, more change can also be had, such as, virtual key generation module according to the custom of user, can be set as left-handed mode or right-handed mode, and adjusts the position of each character keys and the corresponding character inputted accordingly; Or dummy keyboard dynamically adapts to the resolution of touch-screen, and according to the resolution adjustment window size and button size etc. of touch-screen, such change also can realize object of the present invention.

Finally it is emphasized that and the invention is not restricted to above-mentioned embodiment, as the change such as the change of character keys coding method, the change of function button practical function also should be included in the protection domain of the claims in the present invention.
