Description
Technical field
The present invention relates to a kind of apparatus and method that adopt touch screen technology to carry out the character input, particularly a kind of employing touch screen technology is imported the apparatus and method of non-alphabetic class character (for example Chinese character and special character thereof).
Background technology
Prior art is disclosing at least four thousand patent application documents aspect the Chinese character input.From the output instrument, mainly contain inputting method, light is read method of identification (OCR), voice recognition input method and touch-screen method etc.In the inputting method, further comprise phonetic method (be the sound sign indicating number, comprise spelling method, double spelling etc.), order of strokes observed in calligraphy method, stroke and font method (being font code) again, and multiple methods such as phonetic-stroke code with sound sign indicating number and font code combination.
When being used for shortcoming of the all-phonetic input method on the PC, when the operator knocked a key mistakenly, the pairing symbol of this key can be imported in the file of editing.If the operator wants to correct this mistake, he must correspondingly delete the wrong content in the described file.
A shortcoming that is used for the all-phonetic input method of mobile phone is must select frequently during input.For example, when the operator made a kind of mobile phone key in " wa ", he need press the key of a representative " wxyz9 " and another representative " abc2 " respectively, and this moment, the option of this input method acquiescence was " ya ".The operator needs to press " *+" key again for twice, could import " wa " definitely.This is inconvenient to the operator.
A shortcoming of the double-spelling Chinese character input method that uses in the PC is that the operator must expertly remember the position of each consonant key and final key.For the people who does not often import Chinese character, it is difficult keeping this memory muchly.
Used stroke input method in some commercially available mobile phones, for example five basic strokes such as " Dian,, Shu, Pie, Ya ".When having keyed in " Dian, one, Shu, Pie " four keys when the operator is docile and obedient preface, but the word selection that shows on the touch-screen is " wood is thought this sample camera poplar Li Lin totalitarity art ... .. ".Be input " poplar " word, operator or need move down choice menus; Perhaps import a stroke " Ya " again, this moment, the option menu showed is " letter poplar Li Quan root tree is general .... ".The stroke number of input is many more, but the uncertainty of the word selection on the touch-screen is correspondingly just more little.
Though the input speed based on the five-stroke character input method of keyboard is very fast, an one shortcoming is that the operator will remember a large amount of radicals.
Except that above common method, a kind of simplified phonetic alphabet one touching screen mouse Chinese character input method is disclosed among the Chinese patent application CN00120701, adopt two-dimentional character inputting interface, and inputting interface is designed to three of simplicity syllable windows, individual character window, word window is the input forms that Back ground Information constitutes with phonetic, uses click or touch-screen to excite button in the above-mentioned forms can realize the input of Chinese character.A kind of parts--touching screen mouse Chinese character input method is disclosed among another of this application people part Chinese patent application CN00120793, this method adopts two-dimentional character inputting interface, and inputting interface is designed to three of first stroke of a Chinese character parts windows, individual character window, word window is the input forms that Back ground Information constitutes with the font, uses click or uses touch-screen to excite the button in the above-mentioned forms can start corresponding Chinese character input processing procedure input Chinese character.The shortcoming of these two pieces of disclosed technical schemes of Chinese patent application mainly contains two, the one, the key that hundreds of nearly is used to express syllable or radical is arranged on screen, make screen seem very messy, be unfavorable for that the operator finds desirable that syllable or radical rapidly; The 2nd, in phonetic plan, all syllable unit are set directly on the screen, initial consonant and simple or compound vowel of a Chinese syllable are not carried out suitable classification, also be inconvenient concerning the operator therefore.
In addition, also disclosing a kind of user who is used in reference to the sub-device of conduction among the Chinese invention patent ublic specification of application CN1542597A selects this device to go up the method for the key on the keyboard of touch-screen.This method comprises the normal alphanumeric unit that is received in the input of keyboard place, the first of at least one syllable of normal alphanumeric unit marks; Then the database of effective syllable or word is searched for, can be with identification immediately following the effective alphanumeric unit after this normal alphanumeric unit; After this, the key of the effective alphanumeric unit of expression on the outstanding keyboard of this method, thus guides user is selected a key of one of described effective alphanumeric unit of expression.This method can guides user be selected suitable key during the text input, particularly when the user was unfamiliar with keyboard layout, this method can provide effective guidance to the user.But this method still requires the user at first to import the first of at least one syllable, can follow-up input process be instructed and point out then.Thereby the user still is inconvenient in the incipient stage of carrying out the text input.

Then, as shown in Figure 6, the operator continues input alphabet " e ", demonstrate in the described character candidates district 4 this moment " write, tiltedly, a bit, blood, unload, thank, tool " etc. seven Chinese characters.If the operator operates the 6th Chinese character and " thanks " to keyboard in described character candidates district 4, then this " thanks " to word and will be presented on the described character viewing area 5.If the operator does not choose the character in the character candidates district 4 this moment, do not adopt function key that the character of having imported is edited yet, then the operator can not carry out the input of character late immediately.
Example 2, the example of double-spelling Chinese character input method
Adopt character of the every input of double-spelling Chinese character input method, generally need first key of operation (corresponding to the first sign indicating number of the Two bors d's oeuveres of this character), a tail key (corresponding to the Two bors d's oeuveres tail sign indicating number of this character), and a word selection key.Described word selection key is after initial and end two keys inputs, shown some candidate characters in the described character candidates district 4.The operator operates desirable candidate characters key, and described candidate characters is input in the described character viewing area 5.
Referring to Fig. 7 and Fig. 8, wherein Fig. 7 shows when the operator switches to double-spelling Chinese character input method with input method, the residing original state of described touch-screen.At this moment, the first sum of key is 35 keys that can Gong select for use in the input keypad 1.Owing to some single vowel words are arranged in the Chinese character, so these keys of importing first mainly are consonant keys, also comprise part single vowel key, as " a, o, e, ai, ao, ou, er, en... " etc.After the operator has imported first enter key (not shown concrete enter key among Fig. 7), according to the double-spelling Chinese character input method that is adopted, character entry apparatus of the present invention is with being about to the inputting interface that inputting interface switches to second enter key as shown in Figure 8.
Fig. 8 shows under the double-spelling Chinese character input method interface, after operator's input is over first enter key, and the residing state of described touch-screen.The input keypad 1 of this moment comprises 33 final keys (not shown concrete enter key is so all keys all are in state of activation) as shown in FIG..When the coding rule of operator according to double-spelling Chinese character input method, imported second enter key after, the character candidates district 4 of this moment will correspondingly provide one or one group of optional literal or symbol tabulation (not shown among Fig. 8).Operate corresponding literal or symbolic key, then this literal or symbol have just entered described character viewing area 5.If the literal of desired key entry this moment or symbol be not in current character candidates district 4, that can correspondingly press these 4 right sides, character candidates district one by one turns over the screen key, then subsequently will by screen demonstrate first enter key imported and the pairing possible Chinese character of phonetic or the symbol of second enter key representative.Find this Chinese character or symbol, correspondingly press the key that indicates this literal or symbol in described character candidates district 4, then this literal or symbol promptly are presented in the described character viewing area 5.
If when the operator found just to have inputed a character by mistake, he can press " retreating " function key, this function key can not only be wiped that character of just having imported, also can make the interface of described touch-screen return to state when also not importing that wrong character.
For example, when the operator thought input " Europe " word, on the interface of double-spelling Chinese character input method, he pressed " ou " key, and as shown in Figure 9, described character candidates district 4 promptly provides the tabulation of seven relevant Chinese characters.Press first Chinese character " Europe ", this word just is presented on the described character viewing area 5.The input of this word so just is through with.
Again such as, when the operator imported " bending " word mutually, then the initial interface of double-spelling Chinese character input method was as shown in Figure 7.When he presses " w " key, then this moment described touch-screen input keypad 1 forwarded interface as shown in figure 10 to.Under this interface, it is rational having only " a, o, an, en, ang, u, ei, eng " these several final keys.Subsequently, the operator has imported " an " key, and at this moment described touch-screen just is switched to the residing state as Figure 11.
Under the state of Figure 11, described character candidates district 4 occur " ten thousand, objects for appreciation, evening, gulf, intact, bend, bowl " etc. seven Chinese characters.The key of operator's operation " bending " word representative then " is bent " word and will be input on the described character viewing area 5.
Example 3, the example of stroke and character roots input method
When character entry apparatus of the present invention adopts a kind of commercially available stroke and character roots input method software, can construct the Hanzi structure that to import with various strokes and radical unit.
Figure 12 shows apparatus of the present invention when adopting a kind of stroke and character roots input method, the residing state of described touch-screen.At this moment, have 28 strokes and radical on the described input keypad 1.When the operator imports four strokes such as " Shu, Ya,, Shu " successively, described character candidates district 4 occur " in, with, by, product, ask, member, boundary " etc. seven Chinese characters.This moment the operator press " in " key at word place, then this word promptly has been input on the described character viewing area 5.
It is pointed out that and to adopt some kinds of character entry methods.When device of the present invention adopts five-stroke character input method, can enter key be set with two kinds of methods at least.A kind of is that all the Five-stroke Method radicals all are arranged on described input keypad 1 as a key seriatim; Another kind is to make each keyset in the described input keypad 1 become the radical of several the Five-stroke Methods, when the operator has imported several radicals, described device can be according to described input method, draw several rational combinations of these keys (representing radical in this example), and these are made up pairing Chinese character and symbol is presented at described character candidates district 4.This moment, the operator pressed desirable those Chinese characters or symbol, and then this Chinese character or symbol just have been input on the described character viewing area 5.
When Figure 13 imports " poplar " word for adopting a kind of stroke and character roots input method, the view of enter key viewing area 3 and character candidates district 4 and a function key on the described touch-screen.As shown in figure 13, when the operator imports " poplar " word with a kind of stroke and character roots input method, shown as the part above among Figure 13, he imports radical " wood " earlier, and this moment, described character candidates district 4 demonstrated a series of alternative Chinese characters such as " wood, think, basis, sample, phase, machine, poplar ".If this moment, the operator noticed that he can directly press the pairing key of " poplar " word, and " poplar " word is input on the described character viewing area 5 when his desirable " poplar " word had appeared at described character candidates district 4.Perhaps, he also can import a radical “ Ya again on the basis of radical " wood " "; this moment is shown in the part below among Figure 13; Chinese character and series of symbols shown in the described character candidates district 4 is " letter, poplar, Lee, power, root, tree, general ", and he also can make one's options to " poplar " word according to top described step at this moment.
Under each input state at this stroke and character roots input method interface,, show or only show those rational enter keies according to the code table of this character entry method; And,, do not carry out this input command if when the operator presses an irrational enter key mistakenly.
How following mask body introduction chooses concrete character entry method.
Fairly simple situation is that a kind of character entry method only is installed in the character entry apparatus of the present invention.In this case, the Interface Design of described touch-screen is comparatively simple, the conversion when only needing to consider successively to import several keys under an input method aspect between the interface.This conversion for example comprises when using " retreating " and/or function keys such as " insertion ", the variation of interfacial state and how to make in these cases further, reasonably selection.
If two or more character entry methods are installed in character entry apparatus of the present invention, a kind of method is to make choosing of character entry method at the last layer interface of described touch screen interface.That is to say, for the various kinds of equipment that has adopted character entry apparatus of the present invention (as amusement equipment, navigator or bank self-aid apparatus etc.), with for example being pressed to modes such as a few character entry method options button or input method shift key, enter the input and the display interface of a desirable character entry method earlier.
The mode of choosing of another kind of character entry method is to be introduced into a kind of character entry method interface (for example a kind of character entry method interface of acquiescence); In this character entry method interface, press for example desirable the sort of character entry method at least two character entry method selection function key such as " spelling ", " Two bors d's oeuveres ", " radical " of the next one, enter corresponding interface of input method; Perhaps, a character entry method selection function key only is set, press this function key repeatedly, then can for example select desirable that character entry method at least two predefined character entry methods such as " spelling ", " Two bors d's oeuveres ", " radical ", " hand-written ".
Can make various rational arrangements to key position relevant in the various character entry methods according to spirit of the present invention.
The present invention adopts the input method of Chinese character of types such as voice, the order of strokes observed in calligraphy and radical that technical scheme of the present invention is described in the above basically.But these examples are not construed as limiting the invention.In fact, adopt apparatus and method of the present invention can carry out multiple hieroglyphic input services such as Korean, Japanese, Thai, and the input service of all kinds of western language characters.
Introduce above in the content (especially relevant explanation) of character entry apparatus of the present invention, also correspondingly comprised characters input method of the present invention Fig. 2 to Figure 13.Below with reference to Figure 14 and Figure 15, introduce characters input method provided by the present invention from the angle of flow process.
Figure 14 shows the key step of this method briefly for adopting the schematic flow sheet of a character of the inventive method input among the figure.Referring to Figure 14, when the operator used a certain character entry method at one first character of input, he need import the input block of the pairing necessity of this character under the interface of this character entry method, and in the input process of described this character, relevant character entry method can not be switched.
When this first character of input, be introduced into a suitable interface of input method, determine the input block of this character pairing necessity under this character entry method, with these input blocks be called 1-1 input block, 1-2 input block ... the 1-m input block, wherein m is the number of the input block of first character under this character entry method.When the described 1-1 input block of input, pointed out the input block that under this interface, allows input on the described touch-screen, correspondingly choose a required 1-1 input block therein, finish the input of 1-1 input block.If the operator has chosen an input block that is under an embargo and carries out mistakenly, then according to method of the present invention, described character input and display controller 20 can not carried out this instruction.And, according to method of the present invention, can also make setting to described character input and display controller 20, send a signal to the operator at this moment, point out him error correcting input instruction.Then, determine whether described first character has been imported.If also do not have, then correspondingly continue other input block of this first character of input.At this moment, demonstrate the input block of next step permission on the described touch-screen 10, and forbid carrying out irrational input instruction.The operator has imported each input block of described first character so step by step.Can stop input process then, perhaps continue to import other character.
For example, Fig. 4, Fig. 5 and Fig. 6 are respectively when device of the present invention adopts all-phonetic input method to import " x ", " i " and " e " these three keys in succession, the view of described touch-screen.Simultaneously, also show each step that adopts " thanking " word of characters input method input of the present invention in these three synoptic diagram.
Again for example, when adopting 86 editions five-stroke character input method input " suddenly " words, earlier five-stroke character input method is cut in the character entry apparatus, the input keypad of touch-screen demonstrates the ASCII keyboard of a standard at this moment, comprises 26 letter keys and 10 numerical keys.The first step by pressing " c " place the position or with the position at click " c " place, input " c " key; Operate enter key then, input " b " key, input " c " key again.At this moment, the character candidates district 4 of touch-screen demonstrates alternative target, and " suddenly " word and phrase " are galloped ".The operator has finished the input of this word with pressing " suddenly " word position or with the mode of click " suddenly " word position, " suddenly " word being input in the described character viewing area 5.In this process, if the operator has imported an irrational key, then input of character entry apparatus character and display controller can not carried out the instruction of this mistake.For example, after the operator has imported " c, b, c " three keys, if import " g " key mistakenly, then described character input and display controller not only can not be carried out the instruction of this mistake, also can point out this input error in the mode of sound equipment and/or light flash.
Figure 15 shows in the process that adopts the different character of the inventive method input how to switch input method.When one first character of operator's desire input, he introduces a kind of first character entry method in the inputting interface of employed character entry apparatus earlier, one by one imports each input block of described first character then; Then, he can import character thereafter under the interface of this first character entry method, also can run under the situation of the unfamiliar character of this input method then imports described character with other character entry method.For example, when he runs into " nose " word under certain stroke and character roots input method, owing to be unfamiliar with the coding of this word under this character entry method, he can forward character entry method under the all-phonetic input method at this moment, input " b " and " i ", this moment described input media a character candidates district on can occur " than,, close, nose, green, must, keep away ... " etc. a series of candidate.This moment, operator selectable was selected the 4th word, to character viewing area input " nose " word.And for example, when the operator need import a special symbol " ‰ ", he can switch to character entry method the region-position code input method, finishes the input of this character.For another example, when the operator need import an off-gauge pattern symbol, he can switch to hand-writing input method with input method, and the mode of getting with hand or mouse point is finished the input of this word.
If the operator wants to switch character entry method when having imported at least one input block of a character, that or those input block of this character that he can import with the deletion earlier of " retreating " function key, and then select a suitable character entry method to continue input.Also can be provided with, make when switching input method at this moment, ignore the input block that current character has been imported input media; This situation is more convenient for the operator.
Character entry apparatus of the present invention and method are because the characteristic that has next step input of prompting and forbid carrying out the input of unreasonable key, therefore do not need all to be presented on the touch-screen simultaneously input block all in a kind of input method (concerning some character entry method, its input block reaches up to a hundred); Simultaneously, easily the interface of input block related in apparatus of the present invention and the method is more reasonably designed, these can bring very big facility for the operator.
Those skilled in the art are not difficult correctly to understand the purport of character entry apparatus of the present invention and method according to above-mentioned disclosure.
