Description
Technical field
The present invention relates to Chinese character input field, be particularly useful on small-sized digital keyboard, carrying out the Chinese character input.
Background technology
Chinese is as a kind of pictograph language, its minimum language element is called as Chinese character, simultaneously can watch sound and express the meaning, there is fundamentally difference with the alphabetical element of English, therefore, use a major subjects of the treatment facility of Chinese to be: how efficiently to carry out the Chinese character input.Because the Chinese system is made of the Chinese character of thousands of complexity, it is unpractical therefore wanting to create a big keyboard that comprises all Chinese characters; Therefore, the Chinese character coding input method more than hundred kinds that is emerged in the past 30 years all is to be an independently Chinese character by the high level computer graphic user interface with a plurality of key word combined transformations.
These Chinese character coding input methods can mainly be divided into three types according to coding standard:
Any coding (Arbitrary Codes) input method; For example, region-position code and telegram input method are typical coded input methods arbitrarily, and it needs the user to memorize mechanically the hash coding of each Chinese character, obviously is difficult to popularize, and therefore no longer is used gradually;
Pronunciation coding (Pronunciation-based) input method; Wherein, the phonetic method is the pronunciation coded input method of the most widely using, and phonetic input method and Guangdong phonetic input method are respectively Taiwan and area, Hong Kong pronunciation coded input methods commonly used;
Structured coding (Structure-based) input method; For example, Cangjie, five are exactly two kinds of well-known structured coding input methods.
Traditional structured coding input method, Cangjie as mentioned above, five generally is to use 26 Roman character keys on the QWERTY keyboard, shows Hanzi structure according to radicals by which characters are arranged in traditional Chinese dictionaries and stroke.But, along with the development of small-sized handheld digital device, comprise PDA, mobile phone, digital camera and domestic intelligent system, improve constantly for the requirement of effective text input technology.Because these handheld digital device often only provide small-sized numeric keypad, so the Roman character input based on QWERTY keyboard that can not apply mechanically common PC simply and adopted of its input method of Chinese character.
Thus, structured coding input method based on numeric keypad, such as nine side Q9, input method CKC and stroke input method (Stroke Method) are devised in length and breadth, represent stroke or radicals by which characters are arranged in traditional Chinese dictionaries to come encoding Chinese characters with numerical key 0-9, both go for the numeric keypad of handheld digital device, also gone for the numeric keypad of PC.Simultaneously, the pronunciation coded input method also can be continued to use on numeric keypad.
Nonetheless, we still are difficult to find any input method of Chinese character, and it can satisfy the requirement of aspects such as the high efficiency of learnability, input and small-sized digital keyboard applicability simultaneously, below just to existing input method of Chinese character simple analysis in addition:
(1) pronunciation coded input method:
Have advantage easy to learn, the literary style that the user need not to understand these Chinese characters can realize input; With the phonetic method is example, the dictionary that it simply uses pinyin table to transform as Chinese character, and for the people that know mandarin (Mandarin), this input method is obviously very easy to learn; Guangdong assembly and phonetic notation have same advantage for the user of Hong Kong and Taiwan;
But, pronunciation coded input method repetition rate of coding height, and caused the limitation of input speed aspect thus, reason is that many Chinese characters have identical pronunciation; Be example with the phonetic method still, import " Chinese " word, we need input Pinyin letter " han " to realize, but simultaneously, and we will obtain one 100 or the tabulation of how alternative word; Statistics shows that on average each phonetic correspondence 17 different Chinese characters, and this is a relative very high repetition rate of coding, has limited the maximum input efficiency of phonetic method; Especially for the small-sized digital device of limited display length, it is particularly evident that this defective shows.
(2) use the structured coding input method of QWERTY keyboard, it uses Roman character key to shine upon Chinese character radicals and stroke, with the Cangjie that is applicable to the unsimplified Hanzi input be applicable to that five of simplified Hanzi input are representative:
Characteristics with quick input; With five is example, its most important advantage is that its repetition rate of coding is quite low, most common Chinese character all has unique 5-stroke coding, therefore, some common Chinese characters only need 2 key words can realize input, need 4 at most, and no longer need further to select to handle after importing five sign indicating numbers, this is the characteristics of a highly significant, has brought very high input speed thus; By optimizing, five pen input methods can expand to maximum four key words and import a plurality of Chinese characters or phrase, and a trained user can the per minute input surpass 100 Chinese characters; Though a little higher than five of Cangjie's sign indicating number repetition rate of coding is compared with phonetic input method, its advantage aspect input speed is still very obvious;
But above-mentioned input method obviously can't be generalized on the numerical key; Simultaneously, also there is a major defect in above-mentioned input method, finds it difficult to learn exactly and easily forgets.Most user will experience one arduous period when beginning to learn, the definition of key word and the complicated input rule of above-mentioned input method are very difficult to memory.
(3) the structured coding input method of use numerical key, nine side Q9, input method CKC and stroke input method in length and breadth as previously mentioned:
Wherein, Q9 input method and CKC input method use 9 numerical keys (1 to 9) and 10 keys (0to 9) to import Chinese character respectively.With the CKC input method is example, and its institute that will constitute Chinese character might be divided into 10 groups by stroke, is defined in respectively on one of digital 0-9, and the order according to four-corner stroke realizes the Chinese character input for four yards then.In this case, the user need remember 9 or the corresponding respectively key words of 10 keys, and often is mapped with very many radicals by which characters are arranged in traditional Chinese dictionaries or stroke on each key, and this is for being not a duck soup the people of frequent use input in Chinese system; Particularly in CKC, the user also needs to learn new Chinese character is olation;
At present most popular input method of Chinese character is a stroke input method on the mobile phone, because it is a kind of completely based on the method for Chinese character coding of stroke, and therefore very easy; Wherein, 41 strokes of 24 strokes of simplified Hanzi and unsimplified Hanzi are divided into 5 kinds of basic stroke types by the shape based on them, and are as follows:
Horizontal stroke[horizontal stroke]: one
Vertical stroke[is perpendicular]: Shu
Left-Falling stroke[casts aside]: Pie
Right-Falling or dot strokes[point is pressed down]: Dian
Turning stroke[folding]: Ya
Each class stroke type is assigned to a numerical key, generally speaking, uses numerical key 1 to 5.Because the coding of stroke input method is based on the stroke order of handwritten Chinese character, the people that are familiar with Chinese have had abundant understanding to it in the process of learning writing of Chinese characters, therefore greatly reduce the learning difficulty of stroke input method; But, has the complicated Chinese character of a lot of strokes for some, adopting stroke input method will be a job very consuming time, for example, adopt the coding of stroke input method input " Chinese character coding input method " (being the unsimplified Hanzi distinct with simplified Hanzi in the bracket) as follows:
: Shu Ya one Shu among the ■
■ literary composition: Dian one Pie Dian
The defeated: Yi Ya Shu one Pie Dian Yi Shu Ya of ■ is Shu Shu one by one
(Lose: Yi Shu Ya Shu one Pie Dian Yi Shu Ya Shu Shu) one by one one by one
■ goes into: Pie Dian
The ■ method: Dian Dian is Shu Yi Ya Dian one by one
Obviously, for the simple Chinese character with less stroke, such as " going into ", stroke input method is very effective; But,, just need keystroke input many times such as " defeated/Lose " for complicated Chinese character with more stroke; Because variable-length is used in encode Chinese characters for computer in the stroke input method, this has obviously reduced the input speed of the complicated Chinese character with many strokes.
In sum, at present still without any a kind of simple input method of Chinese character, it can have advantage simultaneously at aspects such as the high efficiency of learnability, input and small-sized digital keyboard applicabilities.We are still seeking a kind of so easy, easy-to-use input method, and it can import Chinese character by picture input English easily on the numeric keypad of the numeric keypad of PC or other handheld digital device.

Embodiment
To describe specific embodiments of the invention in detail below.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the present invention.
At first, mandatory declaration is that existing two kinds of main encode Chinese characters for computer modes are respectively standard GB and Big5 in the modern processors; Wherein, GB is the standard of the People's Republic of China (PRC) and Singapore, comprises about 6,500 simplified Hanzis, and Big5 mainly uses in Hong Kong and Taiwan, comprises about 13,500 unsimplified Hanzis.These two numerals--6,500 and 13,500--is very important for the repetition rate of coding parameter of encode Chinese characters for computer, we in an embodiment will be in conjunction with the advantage of these two numeral explanation Chinese character input methods provided by the present invention.
In general, in order to solve the long problem of the input existing coding of complicated Chinese character, we can consider to adopt fixed-length code (FLC).If adopt above mentioned, based on the stroke input method of 5 kinds of base key words, the space encoder of its regular length will be very limited.For example, if use 5 yards, space encoder only is 3,905 (=5+5 so
2+ 5
3+ 5
4+ 5
5), be difficult to satisfy the coding demand of simplified and 13,500 unsimplified Hanzis of 6,500 of codings far away; If use 6 yards 19,530 space encoder (=5+5 is provided
2+ 5
3+ 5
4+ 5
5+ 5
6), though can barely satisfy the basic demand of unsimplified Hanzi, the repetition rate of coding will be very high; Feasible coded system is 7 yards, and 97,655 (=5+5 are provided
2+ 5
3+ 5
4+ 5
5+ 5
6+ 5
7) space encoder, this head and shoulders above the requirement of unsimplified Hanzi 13,500, thereby can effectively reduce the repetition rate of coding, still, 7 yards length can cause the reduction of input speed.
In order between space encoder and input speed, to carry out balance, a kind of Chinese character input method provided by the present invention, it provides a kind of stroke type than stroke input method more, and is taken to many 6 yards inputs, be Six-Digit Base-6, can be called for short the G6 input method.Below we are described in conjunction with specific embodiments.
Please in conjunction with Fig. 1, shown the process flow diagram of Chinese character input method one embodiment provided by the invention, this Chinese character input method is used for Chinese character is converted to and can be input to processor and for its encode Chinese characters for computer of discerning by small-sized digital keyboard by certain step; Wherein, this small-sized digital keyboard can be the numeric keypad of Ke Di qwerty keyboard or the numeric keypad of handheld digital device.
Concrete, this certain step comprises:
S1, the Chinese character that will need to import are decomposed into following 6 kinds of basic stroke types, and be as follows: horizontal (Horizontal strokes), perpendicular (Vertical strokes), left-falling stroke (Left-Falling strokes), point are pressed down (Right-Falling strokes or dot strokes), fold (Clockwise Turningstrokes) and reflexed (Anticlockwise Turning strokes); In order to help to use, these 6 kinds of basic stroke types can indicate as follows on small-sized digital keyboard respectively: one, Shu, Pie, Dian,
And
As can be seen, 6 kinds of basic stroke types of G6 are symmetrical more compared to 5 kinds of stroke types of stroke input method, and promptly each stroke all has the stroke corresponding with it: horizontal and perpendicular, cast aside and right-falling stroke fold and reflexed.Therefore, these 6 kinds of basic stroke types can't be difficult to memory than 5 kinds of stroke types of stroke input method.In order to be memonic, we can also adopt a very simple Chinese pithy formula to represent this six kinds of basic stroke types: one horizontal two perpendicular three left-falling strokes four five are anti-along six.
Preferable, each basic stroke type composed as follows:
(1) basic stroke type " horizontal stroke " comprises at least: one
(2) basic stroke type " is erected " and is comprised: Shu 亅 at least;
Whether some Chinese characters often exist in cataloged procedure need add the doubt that hook changes on perpendicular drawing, such as showing and lack, and caused the confusion of encoding thus; For fear of this problem, the present invention comprises “ 亅 in the basic stroke type " is erected " ".
(3) basic stroke type " left-falling stroke " comprises at least:
(4) basic stroke type " point is pressed down " comprises at least: Dian
(5) basic stroke type " fold " comprises at least:
Ya
Wherein, the stroke standard that is included into " fold " is, at least once turnover takes place this stroke, and its to transfer for the first time be clockwise; Owing to have only turnover for the first time to be used as the sign of identification, therefore classify not difficult to more above-mentioned complicated strokes.
(6) basic stroke type " reflexed " comprises at least:
Wherein, the stroke standard that is included into such is, at least once turnover takes place this stroke, and its to transfer for the first time be counterclockwise; Same, owing to have only turnover for the first time to be used as the sign of identification, therefore classify not difficult to more above-mentioned complicated strokes.
S2, carry out the small-sized digital keyboard setting, comprising: select 6 keys in the key of [0]-[9], the set of this encode Chinese characters for computer comprises the key word of these 6 keys; And, set up of the mapping of these 6 keys respectively to above-mentioned basic stroke type;
As a specific embodiment, 6 keys selecting in the key of [0]-[9] in this step are numerical key [1]-[6]; This mapping steps that is established to the basic stroke type comprises: set up the mapping of numerical key [1] to basic stroke type " horizontal stroke ", set up the mapping that numerical key [2] " erects " to the basic stroke type, set up the mapping of numerical key [3] to basic stroke type " left-falling stroke ", set up the mapping of numerical key [4] to basic stroke type " point is pressed down ", set up the mapping of numerical key [5] to basic stroke type " fold ", and, set up the mapping of numerical key [6] to basic stroke type " reflexed ".Certainly, the selection that it will be understood by those skilled in the art that above-mentioned numerical key is not unique.
Need to prove that simultaneously in order to improve input speed, most of Chinese character input system all provides related Chinese character tabulation when first Chinese character of input, the user can select the Chinese character that is associated from tabulation.In fact, when existing a large amount of related Chinese characters to select for the user, the mode of this related Chinese character is not very effective; The another kind of method that improves input speed is to import the information that surpasses a Chinese character simultaneously, especially imports a phrase.
Chinese character input method provided by the invention is supported the phrase pattern simultaneously, and the Chinese character that promptly needs to import is single Chinese character or phrase.In order to distinguish, the step of carrying out the small-sized digital keyboard setting in this step also comprises: individual character is set finishes key, the input that is used to identify single Chinese character is finished;
Phrase is set finishes key, be used to identify the phrase input and finish; Wherein, described phrase is finished key and is comprised that two words groups are finished key and key finished in the multiword phrase.
As specific embodiment, for the numeric keypad of QWERTY keyboard, numerical key [0] can be set finish key for individual character, for the numeric keypad of handheld digital device, it is that key finished in individual character that central control knob can be set; And it is that two words groups are finished key that numerical key [7] is set, and numerical key [8] is set finishes key for the multiword phrase.
S3, at the most import described Chinese character 6 basic strokes be encoded to processor.
In order to realize at a high speed input, Chinese character input method provided by the invention uses at the most 6 yards to come encoding Chinese characters; Like this, by six kinds of stroke types and the maximum 6 yards inputs of use, can provide 6+6
2+ 6
3+ 6
5+ 6
6=55,986 space encoder much larger than 6,500 and 13,500, is enough to satisfy the coding needs of traditional font and simplified Hanzi.
Concrete, because the Chinese character of input may be single Chinese character or phrase, phrase may be divided into two words groups or multiword phrase again, it is therefore following that we are discussed respectively.
X1. for the situation of single Chinese character, first three is drawn and back three strokes stroke coding (being called for short (3+3) rule) when whole stroke numbers of the Chinese character of needs input can select to import it during more than 6 yards, perhaps, selects input its preceding four strokes and back two strokes stroke coding;
Wherein, (3+3) rule is to use first three stroke and back three strokes, and promptly three tail three comes encoding Chinese characters, and first three is drawn is first, second and third stroke, back three strokes be third from the bottom, two, stroke.For example, under this rule, the coding of " Chinese character coding input method " (being the unsimplified Hanzi distinct with simplified Hanzi in the bracket) is:
In:
Literary composition: Dian one Pie Dian=4134
Defeated:
(Lose a: Shu
One Shu Shu=125122)
Go into: Pie Dian=34
Method:
As can be seen, this 6 yards is very efficiently for the complicated Chinese character of input, does not influence the quick input of simple Chinese character simultaneously; Further be exemplified below (being the unsimplified Hanzi distinct in the bracket) with simplified Hanzi:
Warp:
(The:
Dian Dian Shu one Shu=664121)
Ji: Dian Dian one Dian Pie Shu=441432 (Ji: Dian Dian one Shu one by one=441211)
State: Shu
Dian one=251141 (Country: Shu one by one
One Dian Pie one=251431)
Family: Dian Dian
Pie Pie Dian=445334
Basically, first three draws the radicals by which characters are arranged in traditional Chinese dictionaries that are used to discern complicated Chinese character, in general, uses the three strokes of radicals by which characters are arranged in traditional Chinese dictionaries that can distinguish most of Chinese character, especially for simplified Hanzi; In addition, back three strokes are used to determine the Chinese character with similar or identical radicals by which characters are arranged in traditional Chinese dictionaries.
Suppose that the complicated Chinese character with a certain identical radicals by which characters are arranged in traditional Chinese dictionaries has 300, when we used back three strokes based on 6 kinds of basic stroke types, we accessed 300/6 by average energy so
3=3 repeated codes.Because this repetition rate of coding is less than 9, therefore final alternative same sign indicating number Chinese character tabulation is easy to offer the user, is a kind of interface very friendly for the user.
Obviously, the characteristics of this (3+3) rule make Chinese character input method provided by the present invention have quite high speed.
In addition, (4+2) rule also can be used as encode Chinese characters for computer, but the repetition rate of coding a little higher than (3+3) rule does not repeat them here.
X2. for two words groups, because most of Chinese phrase is made up of two Chinese characters, Chinese character input method provided by the present invention provides special database for two all words groups.By using (3)+(3) rule, when whole stroke numbers of the Chinese character of needs input during more than 6 yards, two words group codings are very simple equally: comprise first Chinese character first three is drawn and back at the most three strokes of second Chinese character constitute 6 yards at the most.Be the codings (in bracket be with simplified phrase distinct traditional font phrase) of some two words groups below according to above-mentioned rule:
Input:
(Lose goes into:
)
China:
(middle Country:

Hong Kong:
Economical:

Because the minimum length of the single encode Chinese characters for computer of G6 is 1, therefore the minimum length of 2 words group codings is 2, and maximum length is 6.In fact, need a special phrase sign key to show not to be single Chinese character but the input of phrase according to the setting of present embodiment step S2, is to realize this purpose by [7] key.
X3. comprise that the phrase more than two words is considered to the multiword phrase, we use (3)+(3) rule that it is encoded equally.Wherein, comprise that first three stroke at the most of first Chinese character and back at the most three strokes of last Chinese character constitute 6 yards.Be the codings (in bracket be with simplified phrase distinct traditional font phrase) of some multiword phrases below according to above-mentioned rule:

As can be seen, Chinese character input method provided by the invention can be supported the Chinese word group coding, thereby improves input speed significantly; For example, if the user word for word imports the coding of " Hong Kong Special Administrative Region " with simplified Hanzi, need 40 yards to import 7 words altogether, and adopt phrase coding provided by the invention, just can be less than the input of one yard coded system realization multiword phrase with average each word.Simultaneously, the rule of this phrase coding also is that easily note is easy-to-use.
Accordingly, embodiments of the invention also provide small-sized digital keyboard, can be the numeric keypad of Ke Di qwerty keyboard or the numeric keypad of handheld digital device.
Concrete, 6 keys in [0] of this small-sized digital keyboard-[9] key are used to import encode Chinese characters for computer, and shine upon following 6 kinds of basic stroke types respectively: horizontal, vertical, cast aside, some right-falling stroke, fold and reflexed.As a specific embodiment, these 6 keys that are used to import encode Chinese characters for computer can be numerical key [1]-[6]; Wherein, numerical key [1] mapping basic stroke type horizontal stroke, numerical key [2] mapping basic stroke type is perpendicular, numerical key [3] mapping basic stroke type is cast aside, numerical key [4] mapping basic stroke type point is pressed down, the fold of numerical key [5] mapping basic stroke type, and, numerical key [6] mapping basic stroke type reflexed.
Simultaneously, in order to support the differentiation to the input of single Chinese character and phrase input, this small-sized digital keyboard is provided with also that key finished in individual character and key finished in phrase.
Please, shown the synoptic diagram of the numeric keypad of QWERTY keyboard in conjunction with Fig. 2.Wherein, numerical key [0] is finished key for individual character, behind the single Chinese character of subscriber-coded key entry, can key in by [0] key notification processor and finish; At this moment, surpass one if having the Chinese character of this coding, system will show all codings with alternative so, and the user can use numeral " 1-9 " key finally to select.Simultaneously, key [0] can also be imported the space as " space (Space) " key between Chinese character.
In addition, [Enter] key can be used as the collateral key that key finished in individual character, is used for quickening the input of individual character commonly used.Because everyday character mostly is first word of repeated code word select word tabulation, so the user as learning from the interface or the known individual character that will import is the first word of tabulation, just can directly use [Enter] key to import this individual character commonly used and need not re-use numeral " 1-9 " key and finally select.
In addition, numerical key [7] is that two words groups are finished key, and numerical key [8] is finished key for the multiword phrase, and numerical key [9] can be used as punctuation key.
