Mixed input mode of the present invention refers to the simultaneously pattern of inputting ideographic literal and phonography.
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, many-one, and the relation of multi-to-multi; Another kind refers to all alphabetic characters except the first phonography, it has comprised the ideograph of common indication, such as Chinese character in the Chinese etc., there is not the phonography that corresponding relation is arranged with ideograph, such 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, in 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 no longer separately explanation, 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 Chinese characters independently one by one.This paper mentions literal and comprises at least a character, 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 concept of this technical field, five kinds of tones of "-' ˇ ｀ " that for example uses in the Chinese phonetic alphabet.
Fig. 1 is the synoptic diagram according to the device of 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: input person's handwriting viewing area 301, for the person's handwriting that shows written character; Recognition result viewing area 303 is used for one group of candidate character character that Identification display obtains; Tone viewing area 401 is for the tone that shows phonography; Ideograph viewing area 304 is used for showing the ideograph corresponding with phonography; Input characters viewing area 302 is used for showing the alphabetic character that is input in the device.
Being in the situation of interactive component adopting touch-screen, also is display module so touch-screen is input module, and this moment, input block 110 and display unit 120 can share a physical interface.Here need to prove that above viewing area can be subject 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 apparent for the relevant technical staff in the field 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 identified according to person's handwriting, provides the identification candidate word, and at step S203, will identify candidate word 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 identify, and other various character recognition algorithms.For example: the method for identifying with feature database, need the alphabetic character characteristic of correspondence data acquisition that storage can supply character recognition unit 220 to identify in storage unit 103 in advance, identifying is about to input 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 alphabetic character group corresponding to these data, so, this literal character group is identified 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.
Identifying 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 comprised of more than one alphabetic character, and this is apparent for the relevant technical staff in the field.
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 the 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 can the Division identification result under the method for kind.According to kind under the recognition result, carry out next step processing.Belong to ideograph if identify first-selected word, to judge that according to the first-selected word of identification the kind of identification candidate result is as example, identify candidate result and namely belong to ideograph this moment, execution in step S208 so, then the first-selected word of Identification display in the input characters viewing area is carried out S209 and is judged whether the user is selecting any literal from the identification candidate word.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 input new literal, returns so step S201, 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 identify 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, identifying first-selected literal is in the ideograph that comprises in the identification sets of candidate characters, come top ideograph, i.e. the ideograph the most similar to the handwriting character in the recognition result.
Among the present invention, judge that the method for kind be the most basic method of this technical field under the alphabetic character, comprise according to zone bit and judging, and judge etc. the method for various differentiation kinds of characters according to the affiliated scope of alphabetic character coding.
Expect input character " roc " as example take the user, 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 identifying candidate result " roc, arm; splash, glue, waist ... " successively, the 303 interior demonstrations in the recognition result viewing area, symbol " ▲ " 305 expressions also have other candidate words, and symbol " ▲ " can be replaced by other similar symbol.In step S204, judge that the first-selected result of identification is ideographic character, that is, belong to ideograph.Then at step S208 input characters viewing area 302 delivered in the first-selected word " roc " in the recognition result.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 so execution in step S208, the upper unacknowledged literal in the input characters viewing area 302 replaced in the literal of user selection, and show.
For example, with reference to top example, successively execution in step S201, S202 and S203, obtain identifying candidate result " arm, roc are splashed; glue; waist ... ", the 303 interior demonstrations in the recognition result viewing area, namely the first-selected result of identification is " arm ", " arm " delivers to input characters viewing area 302 as first-selected word at this moment, rather than " roc " in user's sets of candidate characters of expecting to input, then the user is in step S209, and the user selects character " roc " from sets of candidate characters.Then in step S210, judge the affiliated kind of literal of user selection.Judge to belong to ideograph, therefore return step S208, and in the input characters viewing area 302 interior demonstration selected words " roc ".Because this word is expected the character inputted for the user, therefore, execution in step S216, the input of an ideograph is finished in affirmation.
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, the upper unacknowledged literal in the input characters viewing area 302 replaced in the selected phonography of 302 interior demonstrations in the input characters viewing area; In step S212, ideograph corresponding to the ideograph viewing area selected phonography of 304 interior demonstrations; 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.Ideograph viewing area 304 shows is several ideographs corresponding with top selected 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, thus the literal of judging the at present input required literal of user whether.If the user does not select from recognition result viewing area 303 or ideographic character viewing area 304, think that then the literal in the 302 interior demonstrations of input characters viewing area is required literal, input characters is identified, execution in step S216.
Expect to input the Chinese phonetic alphabet " ni " with the user, belong to phonography, be example, the user by handwriting input unit 110 write "
"; because hand-written distortion is larger, character recognition unit 220 provides the identification candidate result and is: " hi, ni, ri, ... ", corresponding step S201, S202 and S203 are finished; follow execution in step S204; because the first-selected result of identification is " hi ", belong 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, the 302 interior selected literal " ni " that shown have satisfied user's expectation in the input characters viewing area, and the user need not again to select, and behind the execution in step S214, judge that drawing input characters is identified, thereby have 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, namely 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 occured, execution in step S217 continues to carry out and judge so.
With reference to top example, that supposes that the user expects to input is " drowning " word, and the user forgets how to write, and wants to input by the mode of inputting phonography " ni ", then described with top example, the user by handwriting input unit 110 write "
", when carrying out step S217 successively, wherein, in step S212; the 304 interior demonstrations ideograph corresponding with " ni " in the ideograph viewing area: " you, the Buddhist nun, mud, contrary, intend ... ", S213 is at the tone of its support of tone viewing area: "-' ˇ ｀ ", and focus on display current tone.Because the user do not write entering tone when handwriting input, thereby current tone do not exist, and need not focus on display, and simultaneously, do not have softly tone " ", and then " " can not show, if for the simple and unitarity of interface, can keep.Because " drowning " is falling tone, be that tone is " ｀ ", 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 " in the execution in step S211 input characters viewing area, execution in step S212, its corresponding ideograph is updated to: and " mud, contrary, greasy; as to 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.
The above has described the situation that first-selected word in the input recognition result belongs to ideograph, and the situation that word selection headed by the judged result in step S204 belongs to phonography is 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, ideograph corresponding to the input characters viewing area first-selected phonography of 302 interior demonstrations, perhaps first-selected phonography; At step S206, ideograph corresponding to the ideograph viewing area first-selected phonography of 304 interior demonstrations; 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 that the user expects in the situation of the literal inputted the processing the when literal that the user selects belongs to phonography in sets of candidate characters at first-selected ideograph.In addition, step S207 can be used as option, namely 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 was complete, then execution in step S214 continued to judge and carries out.
In the method that the present invention describes, the meaning of "or" is one of them among step S208 and the S205, that is, phonography and ideograph corresponding to this phonography 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 to be shown and remove, namely 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 to be removed, and only supports 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 inputting.
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, input Chinese character and the Chinese phonetic alphabet be as example under the mixed input mode, and be representative, selects in addition touch-screen as interactive unit, input block and display unit take same physical interface like this, describe below in conjunction with specific embodiment.
When the user expects to input Chinese character " roc ", have dual mode to select:
First kind of way, as shown in Figure 3, directly by input block write input Chinese character "
" be presented in the input person's handwriting viewing area 301, according to method provided by the invention, successively execution in step S201, S202 and S203, " roc, arm are splashed, glue, waist to obtain identifying candidate result ... ", the 303 interior demonstrations in the recognition result viewing area.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
Do not have tonal, according to method provided by the invention successively execution in step S201, S202 and S203, obtain identifying candidate result " peng pang neng...... ", the 303 interior demonstrations in the recognition result viewing area, symbol " ▲ " 305 expressions also have other candidate words.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, identifying one of ideograph corresponding to 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 ... " 304 interior demonstrations in the ideograph viewing area, 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 inputting in the ideograph that shows according to the acquiescence tone of the setting of system, in the user selection phonography then, then the input characters viewing area in the display unit shows selected phonography, shown in Fig. 4 B.For example, want the user in the situation of input " roc ", " peng " in the user selection 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 simultaneously the candidate characters corresponding to tone of acquiescence.
Then, execution in step S215 carries out tone and selects.If user selection " ' " in the tone viewing area 401, execution in step S217 then.By execution in step S217, the ideograph " friend Peng Peng roc canopy ... " that the 304 interior demonstrations in the ideograph viewing area " p é ng " are corresponding, and then execution S214 and S215, carry out S210 and S208 according to user selection, 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.
