Mixed input mode of the present invention refers to the pattern of inputting ideographic literal and phonography simultaneously.
In of the present invention, for convenience of description, alphabetic character is classified as two classes: a kind of is the phonography that has corresponding ideograph, for example exist corresponding relation between the Chinese phonetic alphabet and the Chinese character, be referred to as phonography, wherein corresponding relation comprises one-to-many, the relation of many-one and multi-to-multi; Another kind is meant all alphabetic characters except first kind of phonography, it has comprised the ideograph of common indication, as Chinese character in the Chinese etc., there is not the phonography that corresponding relation is arranged with ideograph, as the Hangul in Korean part etc., other symbol such as arabic numeral and punctuation mark is referred to as ideograph.
The invention is not restricted to above-mentioned classification, under the situation that does not break away from the spirit and scope of the present invention, those skilled in the art also can carry out other classification with alphabetic character.
In this manual, if explanation no longer separately, phonography and ideograph refer to according to afore mentioned rules so.
The ideograph that the present invention relates to includes but not limited to Chinese, and the ideograph in Japanese and the Korean, phonography comprise but also be not limited to the Chinese phonetic alphabet, phonetic notation, English, French, German, Latin.The form of expression of phonography generally is the combination of alphabetic string, and ideograph generally is a Chinese characters independently one by one.This paper mentions literal and comprises a character at least, that is, phonography comprises a phonography character at least, and ideograph comprises an ideograph character at least.
Tone is a kind of tone that the part phonography adopts, and is the general notion of this technical field, five kinds of tones of " the-ˊ ˇ ˋ " that for example uses in the Chinese phonetic alphabet.
Fig. 1 is the schematic representation of apparatus according to the execution ideograph of the embodiment of the invention and phonography input.
With reference to Fig. 1, comprise according to the execution ideograph of the embodiment of the invention and the device of phonography input: interactive unit 101, operation processing unit 102, storage unit 103 and communication unit 104.
In the present embodiment, for the convenience of describing, example is divided into following a plurality of zone with display unit 120 as shown in Figure 3 and Figure 4: import person's handwriting viewing area 301, be used to show the person's handwriting of written character; Recognition result viewing area 303 is used to the one group of candidate character character that shows that identification obtains; Tone viewing area 401 is used to show the tone of phonography; Ideograph viewing area 304 is used to show the ideograph corresponding with phonography; Input characters viewing area 302 is used to show the alphabetic character that is input in the device.
Adopting touch-screen is under the situation of interactive component, also is display module so touch-screen is an input module, and this moment, input block 110 and display unit 120 can shared physical interfaces.Here need to prove that above viewing area can be subjected to the restriction of actual screen and share the actual physics zone.In the smaller situation of screen, the screen of mobile phone for example, above-mentioned viewing area can be replaced in the identical position of physical screen respectively and be shown that this is conspicuous for this area person skilled in the process of carrying out input this moment.
Fig. 2 is the process flow diagram according to the method for the execution ideograph of the embodiment of the invention and phonography input.
Determining step S204 as shown in Figure 2, S214 and S215 can carry out in arithmetic logic unit 210.
Each operating process of the method for execution ideograph of the present invention and phonography input is described below in conjunction with Fig. 1 and Fig. 2.
With reference to Fig. 2, at step S201, the user is by handwriting input unit 110 at least one writing words character script of input, the corresponding at least ideograph of this person's handwriting or at least one phonography.
At step S202, character recognition unit 220 is discerned according to person's handwriting, provides the identification candidate, and at step S203, will discern candidate by display unit 120 and be shown as candidate characters.The character identifying method of using in step S202 comprises the method for utilizing feature database to discern, and other various character recognition algorithms.For example: the method for discerning with feature database, need the alphabetic character characteristic of correspondence data acquisition that storage can supply character recognition unit 220 to discern in storage unit 103 in advance, identifying is about to import person's handwriting and transfers characteristic to like this, compare with above-mentioned characteristic set of having stored, therefrom find the most similar characteristic, thereby find these data corresponding character character group, so, this literal character group is discerned candidate result exactly.Wherein, the characteristic comparison algorithm of use is not specific to be a certain algorithm, and this algorithm comprises the various similarity computational algorithms in the area of pattern recognition.
Discerning first-selected word refers to character recognition unit and provides the as a result alphabetic character group the most possible with the input character person's handwriting.The identification candidate result is made up of more than one alphabetic character, and this is conspicuous for this area person skilled.
At step S204, kind under arithmetic logic unit 210 is judged the identification candidate result, determination methods comprises according to the text type under the first-selected word of the identification in the identification candidate characters, perhaps according to phonography in the recognition result and the shared scale of ideograph, the perhaps size of the similarity of phonography and ideograph in the recognition result, and other any method that can distinguish the affiliated kind of recognition result.According to kind under the recognition result, carry out next step processing.Belong to ideograph if discern first-selected word, to judge that according to the first-selected word of identification the kind of identification candidate result is an example, discern candidate result and promptly belong to ideograph this moment, execution in step S208 so, in the input characters viewing area, show the first-selected word of identification, carry out S209 then and judge whether the user is selecting any literal from the identification candidate.If do not select, think that then the literal that shows is required literal in the input characters viewing area, input characters is identified, and carries out S216, if the text input is finished, so whole text input process finishes; If remain unfulfilled, the user will import new literal, returns step S201 so, restarts to carry out the input of fresh character.
The method of kind mostly is to decide kind under the identification candidate result according to kind under the first-selected word of identification under the judgement used in the example of the description of the invention identification candidate result.For example: belong to phonography if discern first-selected word, this identification candidate result belongs to phonography so.Also comprise other determination methods in the method for the present invention's description, if adopt other determination methods, the first-selected word of the identification of this moment refers to satisfy and judges the affiliated kind of recognition result that obtains so, and comes the top alphabetic character of sets of candidate characters.For example: the determination methods that system uses according to reality judges that the identification candidate result belongs to ideograph, at this moment, discerning first-selected literal is in the ideograph that is comprised in the identification sets of candidate characters, come top ideograph, i.e. the ideograph the most similar in the recognition result to the handwriting character.
Among the present invention, judge under the alphabetic character that the method for kind be the fundamental method of this technical field, comprise the method for judging and judge etc. various differentiation kinds of characters according to zone bit according to the affiliated scope of alphabetic character coding.
With user expectation input character " roc " is example, as shown in Figure 3, when write by input block 110 input Chinese character "
" time, in input person's handwriting viewing area 301, show corresponding handwriting input person's handwriting.Execution in step S201, S202 and S203 obtain discerning candidate result " roc, arm; splash, glue, waist ... " successively, show that in recognition result viewing area 303 symbol " ▲ " 305 expressions also have other candidate, symbol " ▲ " can be replaced by other similar symbol.In step S204, judge that the first-selected result of identification is an ideographic character, that is, belong to ideograph.Then input characters viewing area 302 delivered in the first-selected word " roc " in the recognition result at step S208.Reach user's expectation input this moment, therefore, the user no longer carries out other selection from sets of candidate characters, and therefore, input characters is identified, and carries out S216, confirms to finish an ideograph input.
If the judged result in step S209 needs execution in step S210 so for the user has selected any literal again from the identification candidate characters, judge the affiliated kind of selected literal.If belong to ideograph, return execution in step S208 so, the last unacknowledged literal in the input characters viewing area 302 replaced in the literal that the user selects, and show.
For example, with reference to top example, execution in step S201, S202 and S203 successively, obtain discerning candidate result " arm, roc are splashed; glue; waist ... ", show that in recognition result viewing area 303 promptly Shi Bie first-selected result is " arm ", " arm " delivers to input characters viewing area 302 as first-selected word at this moment, rather than " roc " in the sets of candidate characters of user expectation input, then the user is in step S209, and the user selects character " roc " from sets of candidate characters.In step S210, judge the affiliated kind of literal that the user selects then.Judge to belong to ideograph, therefore return step S208, and in input characters viewing area 302, show selected word " roc ".Because this word is the character of user expectation input, therefore, execution in step S216 confirms to finish the input of an ideograph.
If the judged result in step S210 is selected alphabetic character is the watch sound character, belong to phonography, so execution in step S217.Wherein, step S217 comprises step S211, S212 and S213.In step S211, in input characters viewing area 302, show selected phonography, replace the last unacknowledged literal in the input characters viewing area 302; In step S212, show the ideograph of selected phonography correspondence in the ideograph viewing area 304; In step S213, tone viewing area 401 shows tone and its other tone of supporting that selected phonography is current.According to the size of screen, tone viewing area 401 and input characters viewing area 302, recognition result viewing area 303 and ideographic character viewing area 304 can be simultaneously displayed on the same screen, perhaps the operation according to the user is presented on next function screen.What ideograph viewing area 304 showed is and top selected several corresponding ideographs of phonography, its rule of following that puts in order when showing is to obtain according to the tone of input and the relation between the context, context relation can be set by a lot of common methods, for example: word frequency information, word is information frequently, meaning of one's words statistical study etc., and along with the content of user's input is constantly adjusted.The corresponding relation of phonography and ideograph is stored in the storage unit 103.
The execution sequence of the step S211 that comprises among the step S217, S212 and S213 can exchange.After these steps were finished, execution in step S214 judged whether the user has carried out other and selected, thereby judges whether the literal of input is the required literal of user at present.If the user does not select from recognition result viewing area 303 or ideographic character viewing area 304, think that then the literal that shows is required literal in input characters viewing area 302, input characters is identified, execution in step S216.
With the user expectation input Chinese phonetic alphabet " ni ", belong to phonography, be example, the user writes by handwriting input unit 110
Because hand-written distortion is bigger, character recognition unit 220 provides the identification candidate result and is: " hi, ni, ri; ... ", corresponding step S201, S202 and S203 are finished, then execution in step S204, because the first-selected result of identification is " hi ", belongs to ideograph, then execution in step S208.At this moment, execution in step S209, that the user selects desired input from the identification candidate result is " ni ", S210 judges that obtaining " ni " belongs to phonography, then execution in step S217.Wherein, in step S211, shown selected literal " ni " in input characters viewing area 302, satisfied user expectation, the user need not to select once more, behind the execution in step S214, judges that drawing input characters is identified, thereby has finished the input of " ni ".
If at step S214, the user continues to have selected other literal or tone, and execution in step S215 judges whether the user has selected tone so.If the user does not select tone, promptly selected other literal, execution in step S210 continues to judge and carry out so; If selected tone, because the difference of tone is equal to selected phonography variation has taken place, execution in step S217 continues to carry out and judge so.
With reference to top example, what suppose the user expectation input is " drowning " word, and the user forgets how to write, and wants to import by the mode of input phonography " ni ", and then described with top example, the user writes by handwriting input unit 110
When carrying out step S217 successively, wherein, in step S212, in ideograph viewing area 304, show the ideograph corresponding with " ni ": " you; the Buddhist nun, mud, contrary; plan ... ", S213 is at the tone of its support of tone viewing area: "-ˊ ˇ ˋ ", and show current tone emphatically.Because the user do not write entering tone when handwriting input, thereby current tone do not exist, and need not show emphatically that simultaneously, do not have tone " " softly, then " " can not show, if for the simple and unitarity of INTERFACE DESIGN, can keep.Because " drowning " is falling tone, be tone Wei “ ˋ "; the user continues to select tone; execution in step S214 and S215; this moment, then again according to user's selection execution in step S217, this moment, phonography became " n ì ", thereby unacknowledged phonography " ni " is updated to " n ì " execution in step S211 input characters the viewing area in; execution in step S212; its corresponding ideograph is updated to: " mud, contrary, be bored with, drown ... "; the user just can select " drowning ", execution in step S214 successively, S215; S210, thus S208 and S209 input characters " are drowned " and are identified.
Described the situation that first-selected word in the input recognition result belongs to ideograph above, the situation that word selection headed by the judged result in step S204 belongs to phonography has been described below.Be judged as when belonging to phonography, execution in step S218, this step comprises step S205, S206 and S207.Wherein, at step S205, show the ideograph of first-selected phonography correspondence in the input characters viewing area 302, perhaps first-selected phonography; At step S206, show the ideograph of first-selected phonography correspondence in the ideograph viewing area 304; At step S207, the tone that the tone viewing area first-selected phonography of 401 demonstrations is current and other tone of support.These three steps are similar with S213 to step S211, S212 among the S217.Difference is, is the processing to first-selected phonography in step S218, and step S217 is or not under the situation of literal of user expectation input at first-selected ideograph, the processing the when literal that the user selects in sets of candidate characters belongs to phonography.In addition, step S207 can be used as option, promptly can not carry out the demonstration of tone herein.The execution sequence of the step S205 that comprises among the step S218, S206 and S207 can exchange, and after execution in step S218 finished, then execution in step S214 continued to judge and carries out.
In the method that the present invention describes, among step S208 and the S205 " or " the meaning be one of them, that is, the ideograph of phonography and this phonography correspondence can not be simultaneously displayed in the input characters viewing area 302.
When the method that the present invention describes is used for single ideograph input pattern, phonography among step S208, S205 and the S211 need be shown and remove, promptly only show corresponding ideograph.
The method that the present invention describes is used for single phonography input pattern, identification and the demonstration to ideograph among step S202 and the S203 need be removed, and only supports the identification and the demonstration of phonography.In addition, do not consider the corresponding relation of phonography and ideograph, under this pattern, think that there is not corresponding ideograph in all phonographys, so the judged result of execution in step S204 and S210 must be ideograph.
The method that the present invention describes is particularly useful for ideograph and phonography mixes the pattern of importing.
Describe the method and apparatus of execution ideograph provided by the present invention and phonography input in detail below in conjunction with specific embodiment.
Because Chinese character is a kind of of ideograph, the Chinese phonetic alphabet is a kind of of phonography, and corresponding relation is arranged between the two, so in an embodiment of the present invention, be example with the input Chinese character and the Chinese phonetic alphabet under the mixed input mode, representative, select for use touch-screen as interactive unit in addition, input block and display unit take same physical interface like this, describe below in conjunction with specific embodiment.
When user expectation input Chinese character " roc ", have dual mode to select:
First kind of mode as shown in Figure 3, directly write the Chinese character of input by input block
Be presented in the input person's handwriting viewing area 301, according to method provided by the invention, execution in step S201, S202 and S203 obtain discerning candidate result " roc, arm are splashed, glue, waist ... " successively, show in recognition result viewing area 303.Execution in step S204 and S208 deliver to input characters viewing area 302 with the first-selected word " roc " in the recognition result.Reach user's expectation input this moment, execution in step S216 confirms to finish an ideograph input.
The second way shown in Fig. 4 A, is write input by input block
There is not tonal, according to method provided by the invention execution in step S201, S202 and S203 successively, obtain discerning candidate result " peng pang neng...... ", show in recognition result viewing area 303, symbol " ▲ " 305 expressions also have other candidate.Execution in step S204, judged result belongs to phonography for the first-selected result of identification, so step S205 and S206 among the execution in step S218, discerning one of the corresponding ideograph of first-selected word " peng " " friend " shows in input characters viewing area 302, " peng " its corresponding ideograph " friend bumps and holds in both hands Peng Peng ... " shows in ideograph viewing area 304, because there is not the restriction of tone, so put in order when the showing rule followed only obtains according to the relation between the context.
In diagram, because the screen size restriction does not also have the position of tone viewing area 401 this moment, the user can't select tone this moment.Next execution in step S214, judge in the phonography whether user selected to show in the recognition result viewing area 303 or the ideograph having selected to show in the ideograph viewing area 304 in one.If do not exist the user to want the alphabetic character of importing in the ideograph that shows according to the acquiescence tone of the setting of system, then the user selects in the phonography one, and then the input characters viewing area in the display unit shows selected phonography, shown in Fig. 4 B.For example, want the user under the situation of input " roc ", the user selects " peng " in the recognition result viewing area 303, show selected phonography " peng " in the input characters viewing area 302, tone viewing area 401 has taken original recognition result viewing area 303, and demonstrate 5 tones that " peng " can support, in ideograph viewing area 304, show the candidate characters of the tone correspondence of acquiescence simultaneously.
Then, execution in step S215 carries out tone and selects.If the user has selected De “ ˊ in the tone viewing area 401 ", execution in step S217 then.By execution in step S217, in ideograph viewing area 304, show the ideograph " friend Peng Peng roc canopy ... " that " p é ng " is corresponding, and then execution S214 and S215, select to carry out S210 and S208 according to the user, Chinese character " roc " just shows in input characters viewing area 302 and replaces original this locational phonography " peng ", thereby finished the input of " roc " word, carried out S216, confirmed to finish an ideograph input.
