Embodiment
For quote and know for the purpose of, hereinafter the technical term of Shi Yonging, write a Chinese character in simplified form or abridge to sum up and be explained as follows:
Initial consonant blurs sound: zh and z, ch and c, and sh and s, n and l, h and f, r and l etc. are initial consonant mush sound each other;
Simple or compound vowel of a Chinese syllable blurs sound: ang and an, and eng and en, ing and in, iang and ian, uang and uan etc. be the fuzzy sound of simple or compound vowel of a Chinese syllable each other;
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The inventor finds, Chinese character handwriting inputting method need be discerned according to the Chinese character pattern of user's handwriting characters, this just requires the user to know the literary style of Chinese character, when in case the user runs into the word that can not write, conventional practice is need switch to other hand-writing input methods or non-hand-written spelling input method is finished the identification of handwriting characters, and the switching of carrying out input method will increase user's operation easier significantly and influence user's operating speed.
In view of this, the embodiment of the invention discloses a kind of handwriting characters recognition methods, with the identification of under the situation of not switching input method, finishing handwriting characters and the input of further finishing Chinese character.
Referring to Fig. 1, said method comprises the steps: at least
S11, obtain handwriting characters;
S12, described handwriting characters is discerned:
S121, when described handwriting characters is identified as phonetic, search with described handwriting characters the Chinese character that is associated of corresponding phonetic, and show described Chinese character;
S122, when described handwriting characters is identified as Chinese character, search the Chinese character that is associated with described handwriting characters, and show described Chinese character.
In order to call conveniently, existing " when described handwriting characters is identified as phonetic, searching the Chinese character that is associated with described handwriting characters institute corresponding phonetic " among the step S121 is called, carry out phonetic to handwriting characters and discern; " when described handwriting characters is identified as Chinese character, searching the Chinese character that is associated with described handwriting characters " among the step S 122 is called handwriting characters carried out Chinese Character Recognition.
As seen, the handwriting characters recognition methods in the present embodiment both can be carried out phonetic identification to handwriting characters, also can carry out Chinese Character Recognition to it.When the user runs into the situation that word can not write, only need the handwriting input pinyin character, can carry out phonetic identification to it, search and demonstrate the Chinese character that is associated with this hand-written pinyin character, the user selects to finish the input of Chinese character again to shown Chinese character.In this process, need not to carry out input method and switch and to finish the identification of handwriting characters and further finish the input of Chinese character, thereby reduced user's operation easier and improved its operating speed.
In another embodiment of the present invention, the implementation procedure of above-mentioned phonetic identification can be: the font to handwriting characters carries out the identification of phonetic font, when the font of above-mentioned handwriting characters conforms to a certain or some phonetic font, search and above-mentioned a certain or Chinese character that the pairing phonetic of some phonetic font is associated.
It should be noted that with Chinese character pattern and compare that the phonetic font is simpler, so phonetic identification is also faster compared to Chinese Character Recognition speed.But the prerequisite of phonetic identification is that the user need know the pronunciation that is intended to import Chinese character, and when the user runs into the Chinese character that can not read, direct handwriting input Chinese character in the present embodiment, use the mode of Chinese Character Recognition that it is discerned, can search and demonstrate the Chinese character that is associated with this handwriting input Chinese character, the user selects to finish the input of Chinese character again to shown Chinese character.
In addition, above-mentioned phonetic identification also can be supported fuzzy sound (fuzzy sound mainly comprises fuzzy sound of initial consonant and the fuzzy sound of simple or compound vowel of a Chinese syllable).For example: when the user imports initial consonant " zh ", it can be identified as simultaneously " zh " and " z " (vice versa), and when the user imports simple or compound vowel of a Chinese syllable " ang ", it can be identified as simultaneously " ang " and " an ".Use with the user that conveniently says some dialect (pairing initial consonant of the pronunciation of some words in dialect and/or simple or compound vowel of a Chinese syllable are different with pairing initial consonant of the pronunciation in the mandarin and/or simple or compound vowel of a Chinese syllable).
In another embodiment of the present invention, above-mentioned search with described handwriting characters the specific implementation of the Chinese character that is associated of corresponding phonetic can be:
Whether judgement existed prefix character before described handwriting characters;
When having prefix character, search with the phonetic of described prefix character and described handwriting characters the Chinese character that is associated of corresponding phonetic;
Sub for example, behind user's handwriting characters " you " or " ni " and selection " you " word, handwriting characters " h " again, because there is prefix character " you " before in " h ", therefore search the Chinese character that is associated with " you " and " h ", may demonstrate " good ", " going back ", " meeting ", " with ", Chinese characters such as " very ", " going back "; Perhaps, as the continuous handwriting characters of user " you " and " h ", because there is prefix character " you " before in " h ", therefore search the Chinese character that is associated with " you " and " h ", may demonstrate Chinese characters such as " hello ", " you also ", " your meeting ", " you with ", " you very ", " you and ".Can dwindle the scope of at user option Chinese character so as much as possible, realize searching comparatively accurately, improve seek rate.
And when not having prefix character, search with described handwriting characters the Chinese character that is associated of corresponding phonetic.
The inventor finds simultaneously, the tradition Chinese character hand-writing input method always is used as Chinese character to letter and is handled, therefore when the user needs hand-written letter (for example English, German, French etc.), must switch to the input that other input method such as English input method just can be finished letter.For convenience of user's handwriting input letter, in another embodiment of the present invention, above-mentioned handwriting characters recognition methods also can comprise the steps: when described handwriting characters is identified as letter, searches the alphabetic character and the demonstration that are associated with described handwriting characters.Thereby the purpose that realizes to switch input method and finish the letter input.
In addition, phonetic identification and alphabetical identification can be referred to as non-Chinese Character Recognition, and therefore when the above-mentioned handwriting characters recognition methods of specific implementation, phonetic is discerned and alphabetical identification can be carried out simultaneously, and a kind of concrete mode wherein is:
The font of handwriting characters is carried out the font identification of non-Chinese character pattern;
After discerning successfully, judge before described handwriting characters, whether there is prefix character by non-Chinese character pattern;
When having prefix character, search with the phonetic of described prefix character and described handwriting characters the Chinese character that is associated of corresponding phonetic and showing, and when not having prefix character, search with described handwriting characters the Chinese character that is associated of corresponding phonetic and showing, and search the alphabetic character that is associated with described handwriting characters and show;
When by behind the font recognition failures of non-Chinese character, the font of described handwriting characters is carried out the font identification of Chinese character pattern;
After pressing Chinese character pattern and discerning successfully, judge before described handwriting characters, whether there is prefix character;
When having prefix character, search the Chinese character and the demonstration that are associated with described prefix character and described handwriting characters, and when not having prefix character, search the Chinese character and the demonstration that are associated with described handwriting characters.
It should be noted that when having prefix character, search with the phonetic of described prefix character and described handwriting characters the Chinese character that is associated of corresponding phonetic can be described as the association forward of phonetic; And when having prefix character, search the association forward that the Chinese character that is associated with described prefix character and described handwriting characters can be described as Chinese character; Accordingly, also have the association backward of Chinese character, so-called association backward promptly refers to, after the user has selected Chinese character, searches the Chinese character and the demonstration of being everlasting and using with user-selected Chinese character.For instance, when the user chooses " good " this Chinese character, demonstrate " ", " as " etc. Chinese character.Certainly, also can with phonetic forward the association, Chinese character association forward and backward association be referred to as association.
Be understandable that, above-mentioned concrete mode can realize phonetic, Chinese character mixes association, for example: elder generation's hand-written input Chinese character " you ", the part of hand-written more afterwards phonetic or phonetic, such as handwriting characters " h " (" you " become the prefix character of " h " at this moment), can search and demonstrate " good ", " go back ", " meeting ", " with ", " very ", Chinese character (association forward of phonetic identification) such as " go back ", certainly also can show also character " h " itself, after the user selects " good " this Chinese character, will then search again and demonstrate " ", " as " etc. Chinese character (Chinese character is associated backward).
Because with respect to Chinese character, the number of non-Chinese character is few, and font is simple, so above-mentioned concrete mode can be at first the character of user's handwriting input is carried out non-Chinese Character Recognition.Those skilled in the art also can be adjusted recognition sequence as required, do not give unnecessary details at this.
Corresponding with above-mentioned handwriting characters recognition methods, the embodiment of the invention also provides a kind of handwriting characters recognition system simultaneously, and Fig. 2 shows a kind of structure of this system, comprising:

After the user selected to enter the unlatching handwriting functions, handwriting pad was opened, and the user can be at hand-written district 1 handwriting characters.At this moment, referring to Figure 10, the function that functional areas 3 show is respectively cancellation, space, line feed and switching, wherein, last that the hand-written Chinese character of " cancellation " expression deletion, space of " space " expression input is in input frame 4, and " line feed " is illustrated in newline in the input frame 4, and " switching " expression switches to other input method;
After hand-written district 1 got access to handwriting characters, when above-mentioned handwriting characters can carry out non-Chinese Character Recognition and unmatched asyllabia symbol, alternative district 2 demonstrated the alphabetic character that the Chinese character that is associated with this handwriting characters and this handwriting characters are associated; When above-mentioned handwriting characters can carry out non-Chinese Character Recognition and prefix character is arranged, alternative district 2 demonstrate with the phonetic of described prefix character and described handwriting characters the Chinese character that is associated of corresponding phonetic, and the alphabetic character that is associated with this handwriting characters; When above-mentioned handwriting characters can carry out Chinese Character Recognition and prefix character is arranged, alternative district 2 demonstrated the Chinese character that is associated with described prefix character and described handwriting characters; And when above-mentioned handwriting characters can carry out Chinese Character Recognition and unmatched asyllabia symbol, alternative district 2 demonstrated the Chinese character that is associated with described handwriting characters.
For instance: there is similarity in the user owing between a plurality of Chinese character patterns, and considers the hasty and careless property of writing itself at hand-written district 1 hand-written " you " word, and referring to Figure 11, alternative district 2 demonstrates alternative words such as " you ", " title ", " rent land "; And if the user is at hand-written district 1 hand-written phonetic " ni ", referring to Figure 12, alternative district 2 demonstrates alternative words such as " ni ", " you ", " contrary ", " mud ", " Ni ", " being bored with ", " hideing ", occur a little triangle in alternative district 2 sometimes, it is also meaningful to be shown little triangle interval scale to occur.In addition, the user also can select to open fuzzy sound function as required, does not give unnecessary details at this.
No matter be hand-written " you " or " ni ", the user after alternative word " you " is selected in alternative district, referring to Figure 13, input frame 4 shows Chinese characters " you ", and the function that functional areas 3 show becomes cancellation, space, stops association (be defaulted as and open association function) and switch.Under the state of opening association, alternative district 2 also will show " ", " ", " certainly ", " good ", " having ", " family ", " striving " etc. are with " you " the be everlasting alternative word of logotype.Stop association if the user clicks at this moment, then alternative district 2 can not demonstrate words such as " ", " ".
If the user continues in hand-written district 1 hand-written " h ", referring to Figure 14, alternative district 2 will demonstrate " h " and " meeting ", " good ", " with ", the alternative word that is associated simultaneously of " very ", " going back " etc. and " you " and " h ";
If the user continues in hand-written district 1 hand-written " a ", referring to Figure 15, this moment, hand-written district 1 was shown as " ha ", and alternative district 2 will demonstrate the alternative word that " ha " and " good ", " going back " etc. and " you " and " ha " are associated simultaneously;
If the user continues in hand-written district 1 hand-written " o ", referring to Figure 16, this moment, hand-written district 1 was shown as " hao ", and alternative district 2 will demonstrate alternative word " hao " and " good ".
It should be noted that some Chinese characters, as " one ", " two " etc., can by directly in the mode of the hand-written district of present embodiment 1 handwritten Chinese character to reach the purpose that improves operating speed.And the more Chinese character of some strokes, as " ancient cooking vessel " word, the mode that can be chosen in hand-written district 1 hand-written phonetic " ding " improves operating speed.When importing, can according to circumstances carry out flexible operating.Also promptly, the handheld device that present embodiment provided has higher flexibility in the Chinese character input.
In addition, except Chinese character, English, the user also have sometimes input digit (as the input handset number), punctuate and symbol (as " and [", " $ ", " # " etc.) needs.The user can adopt and switch to digital inputting method and carry out numeral input, and modes such as keyboard input punctuate, symbol are realized.Certainly, also can be designed in alternative district 2 (referring to Figure 17) or functional areas 3 show the function of " numeral ", " punctuates ", " symbol ", with user friendly input.
The user just under the situation of hand-written district 1 hand-written character, can click the blank space in alternative district 2, promptly demonstrate " numeral ", " punctuate ", " symbol " in the alternative district 2, when the user clicks " numeral ", referring to Figure 18, alternative district 2 gets final product display digit, in like manner, can be implemented in alternative district 2 and show punctuate and symbol.
Certainly, the implementation that other also can be arranged, such as, owing to have only " 0-9 " 10 numerals, therefore can in hand-written district 1, directly mark the demonstration of a zone (this position, zone can be adjusted according to actual conditions) as numeral, only need to click this zone and can demonstrate numeral, the user clicks the numeral that just can show in input frame 4 that institute's desire shows again.The demonstration of punctuate, symbol also can be adopted similar mode.
As seen, the handheld device that present embodiment provided is Chinese Character Recognition and phonetic identification simultaneously, and no matter the user runs into Chinese character can be read can not write, or Chinese character can write situation about can not read, and all can realize the identification to handwriting characters under the situation of not switching input method.Present embodiment is also considered the situation of input alphabet, numeral, punctuate, symbol, further make the user under the situation of not switching input method, realization is to the input of letter, numeral, punctuate, symbol, thereby greatly facilitate user's use, reduced the user operation easier, improved its operating speed.
