Abstract
The present invention relates to a high-speed Chinese handwriting inputting method. A Chinese character input area is divided into a plurality of big square areas used as handwriting identifying areas, wherein each big square area is divided into four small square areas. The radicals (or the strokes) of Chinese characters can be independently identified in each small square area in the big square areas. Moreover, the radical (or the strokes) of each Chinese character and the information of the area of the radical are used as independently identifying elements. Thus, the associational recognition of single characters, phrases and sentences is carried out. On the basis of the division of the areas, when a user writes, the shape of each stroke and the area positions of the big square areas are immediately captured, and then, the information is used for associating the character that a user wants to write. Writing strokes of the Chinese characters input in the user's writing recognition process is reduced as far as possible by the measures, and thus, high-speed Chinese character handwriting is realized.
Description
Affiliated technical field
The invention belongs to computer Chinese-character hand-writing input method technical field.
Background technology
At present, the Chinese character handwriting inputting method that is applied to computing machine " handwriting pad " input equipment is very universal, mainly contain " Chinese king " hand-writing input method, " patriot " hand-writing input method, Microsoft's hand-writing input method etc., all as the software kit of " handwriting pad " hardware device in market sale.These input methods are discerned Chinese character according to the stroke that the user writes on " handwriting pad " equipment, and convert the coding that computing machine can be discerned to.
There is following some shortcoming in the common hand-writing input method in market now:
1, recognition speed is slow, has only about per minute 20-30 word, after each wordbook is write, needs the pause in several seconds.This mainly be because existing hand-writing input method be the user writes complete Chinese character after, just begin to discern and general writing Chinese characters as broad as long, can not embody the advantage of computing machine itself fully.Import the required stroke of writing of Chinese character if can reduce the user as much as possible, that will promote the speed of Chinese character hand-written identification greatly.
2, have only word association, just can provide the association word relevant after promptly only having write a word, and not have individual character to associate with this word, can provide relevant associative Chinese character after promptly having write a stroke.Word association simultaneously is imperfection also, has only the association of two word words mostly, and lacks multiword word associative ability.This mainly is because existing hand-writing input method adopts full frame input or writes regional input mode, can easily not recognize the room, for instance, " People's Republic of China (PRC) ", in a lot of inputting methods, can carry out association's input according to the coding of head and the tail Chinese character, if and in existing Chinese character handwriting inputting method, write " in ", " state " two words, then can only be identified as word " China ", if being arranged, a kind of hand-writing input method can discern the room, then " in ", keep 5 rooms in the middle of " state " two words, promptly " in ", " ", " ", " ", " ", " ", " state ", computing machine just can be identified as it " People's Republic of China (PRC) " easily like this, thereby has significantly reduced the stroke of required input, has accelerated input speed.
3, writing plane and display plane are inconsistent, influence the user and control lettering pen, do not meet traditional paper writing custom, have further influenced input speed.This mainly is because existing handwriting pad equipment is not easy and the graphoscope combination, addressing this problem can be with reference to another invention of inventor, " adopt the touch screen optical system of step type parallel light beam extending lens group ", number of patent application: 02108603.6.The present invention and above-mentioned institute propose invention and are used in combination, and can receive better effect.
Summary of the invention
In order to overcome the existing slow shortcoming of handwritten Chinese character input method recognition speed, the invention provides a kind of quick handwritten Chinese character input method, reduce the user as much as possible by technology such as " matts position handwriting recognition ", " the individual character stroke is associated handwriting recognition fast " and " association of individual character radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position ", " association of word radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position ", " associations of word room " and import the required stroke of writing of Chinese character, thereby realize the fast Chinese character handwriting input.
The technical solution adopted for the present invention to solve the technical problems is:
1, " matts position handwriting recognition ", be exactly on computer screen, with a plurality of grid types zone as the handwriting input identified region, according to the design feature of Chinese character, this grid can be the sphere of movements for the elephants lattice, and a Chinese character can be imported in each sphere of movements for the elephants type zone, four less square area in each sphere of movements for the elephants type of while, also independently (or in several little square area) discern Chinese character radicals (or stroke).
2, " association of individual character radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position ", " association of word radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position ", by " matts position handwriting recognition " technology, we can carry out association's identification of individual character, word, sentence with the radicals by which characters are arranged in traditional Chinese dictionaries (or stroke) of each Chinese character as independent recognition element.When we encode all Chinese characters, word and common word combination, common expressions combination according to this rule, after setting up association's dictionary, the coding that obtains after just can writing according to the user is searched for association's dictionary, finds corresponding association individual character or word.
3, " association of word room ", because the present invention provides a plurality of sphere of movements for the elephants types zone on display, thus can be by keeping the mode in respective numbers room, and the long word of association's identification is as " People's Republic of China (PRC) ".
4, " the individual character stroke is associated handwriting recognition fast ", exactly when the user writes, computing machine is caught the shape and the position of stroke in sphere of movements for the elephants type zone of each stroke immediately, the association of retrieval foundation in advance discerns character library then, and the association word that retrieves is presented on the display, select for the user
The invention has the beneficial effects as follows: make the Chinese character hand-written input speed improve, can reach in theory more than the per minute 50-70 word, a kind of new selection of quick input Chinese character is provided for the people who begins to learn computer and get used to writing, simultaneously also can avoid people to forget the mode of Chinese-character writing in computer age, help keeping cultural tradition, great social significance is arranged.
Embodiment
1, " matts position handwriting recognition "
This is basis of the present invention, and its scheme is:
On computer screen, as the handwriting input identified region, the user needs to write in this zone, so that Chinese Character Recognition with a plurality of sphere of movements for the elephants types zone.
A Chinese character can be imported in each sphere of movements for the elephants type zone, and is identical with " frame input " technology of existing Chinese character handwriting inputting method.
Four less square area in each sphere of movements for the elephants type of while, also independently (or in several little square area) discern Chinese character radicals (or stroke), and give corresponding radicals by which characters are arranged in traditional Chinese dictionaries in its zone with " radicals by which characters are arranged in traditional Chinese dictionaries position " coding.
" radicals by which characters are arranged in traditional Chinese dictionaries position " totally 16 can stipulate following (bracket in for scale-of-two): the upper left corner is encoded to 1 (0001), the upper right corner is encoded to 2 (0010), the lower left corner is encoded to 3 (0011), the lower right corner is encoded to 4 (0100), the first half is encoded to 5 (0101), Lower Half is encoded to 6 (0110), the left side is encoded to 7 (0111), right-hand part is encoded to 8 (1000), three little square area of removing the upper left corner are encoded to 9 (1001), three little square area of removing the upper right corner are encoded to 10 (1010), three little square area of removing the lower left corner are encoded to 11 (1011), three little square area of removing the lower right corner are encoded to 12 (1100), the upper left corner and the lower right corner are encoded to 13 (1101), the upper right corner and the lower left corner are encoded to 14 (1110), and whole four little square area are encoded to 15 (1111), and whole four little square area are that sky is encoded to 0 (0000).
For instance, when we write " portion " word, " standing " should be positioned at the upper right corner, so its " radicals by which characters are arranged in traditional Chinese dictionaries position " is encoded to " 1 ", in like manner " mouth " is " 3 "; " Fu " is " 8 ".
Being encoded to of " portion " word then: " standing " 1, " mouth " 3, " Fu " 8.(wherein each radicals by which characters are arranged in traditional Chinese dictionaries coding that can adopt the GB2312 word to concentrate of the coding after the machine identification as calculated also can adopt self-defined " radical-code ").
Coded font should adopt the database form, can import any one radicals by which characters are arranged in traditional Chinese dictionaries as searching item, finds corresponding Chinese Character Set.That is to say no matter we write " standing " 1 in corresponding position, " mouth " 3, " Fu " 8 can find the character set that contains " portion " word.
2, " association of individual character radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position ", " association of word radicals by which characters are arranged in traditional Chinese dictionaries (stroke) position "
By " matts position handwriting recognition " technology, we just can be with the radicals by which characters are arranged in traditional Chinese dictionaries (or stroke) of each Chinese character as independent recognition element, and the association that carries out individual character, word, sentence has discerned.
When we encode all Chinese characters, word and common word combination, common expressions combination according to above rule, after setting up association's dictionary, the coding that obtains after just can writing according to the user is searched for association's dictionary, finds corresponding association individual character or word.
Such as, when our left-half in sphere of movements for the elephants type zone is write " Si ", can obtain coding: " Si " 7, thereby associate " spinning ", " knitting " ... Deng Chinese character, show simultaneously wherein the most frequently used several according to the frequency of utilization of Chinese character.
For another example, word " coding ", we can write " Si " and " stone " in two adjacent sphere of movements for the elephants type zones, then can obtain following code: " Si " 7| " stone " 7 (" | " is in order to represent two independently Chinese characters).
Such as " Rui " 7| " Bing " 7, can associate and be words such as " peace and quiet ", " cleaning ".
Sphere of movements for the elephants type zone also can be simultaneously as the viewing area of associating individual character, word, so that the user selects speech.
Such as when our left-half in sphere of movements for the elephants type zone is write " Si ", the most frequently used alternative Chinese character is presented in two less square area of right half part, and we can click alternative Chinese character output to other softwares.
For another example, we are writing Chinese characters " volume " in first sphere of movements for the elephants type zone, then can show " editor ", " writing ", " coding " in second sphere of movements for the elephants type zone ... Deng association's word.
3, " association of word room "
Because the present invention provides a plurality of sphere of movements for the elephants types zone on display, so can be by keeping the mode in respective numbers room, the long word of association's identification.
Such as,
" know ", " ", " ", " power " can be associated and is " intellecture property ".
" in ", " ", " ", " ", " ", " ", " state ", can associate and be " People's Republic of China (PRC) ".
4, " the individual character stroke is associated handwriting recognition fast "
Existing hand-writing input method need carry out integral body identification after the user has write all strokes, this has influenced input speed, so the present invention realizes real-time association's identification by " the individual character stroke is associated fast " technology.
Specifically, exactly when the user writes, computing machine is caught the shape and the position of stroke in sphere of movements for the elephants type zone of each stroke immediately, then association's identification character library of retrieval foundation in advance, and association word is presented on the display, select for the user.
The basic strokes of Chinese character is: horizontal, vertical, cast aside, press down, carry, hook,
Its presentation direction is respectively: →, ↓,
That is to say that computing machine captures the position of writing pencil nib (being the mouse down state) and constantly moving to all directions.
Vector between " the last position coordinates " of " current position coordinates " that mouse scans each time and preceding single pass approximately is positioned at following interval respectively: 90 the degree ± 5 the degree, 180 the degree ± 5 the degree, 225 the degree ± 30 the degree, 135 the degree ± 30 the degree, 45 the degree ± 30 the degree, 315 the degree ± 30 the degree,
We can be encoded to it respectively: horizontal (0000), perpendicular (0001), cast aside (0010), press down point (0011), carry (0100), hook (1001),
Combined pen divides " folding " into, i.e. in same stroke (the writing pencil nib begins not leave the handwriting pad induction planes from the first stroke of a Chinese character), vector between " current position coordinates " and " last position coordinates " changes greater than 50 degree, can Unified coding be: folding (1010), also can further be subdivided into cross break (1011), perpendicular folding (1100), left-falling stroke folding (1101).Complicated strokes such as cross break crotch are only got its preceding two basic strokes and are encoded.
For " the perpendicular left-falling stroke " as " jin " word left side, strokes such as " horizontal right-falling strokes " below " Chuo " can have more actual conditions and be identified as perpendicular (0001) and horizontal codings such as (0000), rather than left-falling stroke on the traditional understanding (0010) and right-falling stroke (0011), so that the unification of coding reduces the complexity of software programming.
Individual character stroke association coded font also should adopt the database form, can associate the Chinese Character Set that contains target characters according to any stroke, such as " showing ", we can omit top " day " word, the first stroke of a Chinese character " point " of " already " word below directly writing, its position is " 3 (0011) ", and then we can directly inquire some Chinese characters that contain " showing " word according to the coding of " pressing down point (0011), 3 (0011) ".Can reduce the repetition rate of coding of Chinese character like this,, and directly write other less radicals by which characters are arranged in traditional Chinese dictionaries of repetition rate, improve the hit rate of association because the user can omit " pictographic element of a pictophonetic " that " Si ", " stone " etc. easily repeat.
Such as, when the user in zone, the upper left corner (position 1) when writing " left-falling stroke ", constantly is moving below left the position that computing machine captures writing pencil nib (being the mouse down state), that is to say, vector between " the last position coordinates " of " current position coordinates " that mouse scans each time and preceding single pass is positioned at 30 and spends to when 60 degree are interval, computing machine with present stroke encoding is: (" left-falling stroke ", position 1).
So just can in dictionary, begin to retrieve all to cast aside Chinese characters of the first stroke of a Chinese character,, and incite somebody to action the wherein the highest several viewing areas that are presented at of frequency of utilization as the Chinese character by all golden words, such as " " ...
Like this, can make a lot of everyday characters realize that writing a stroke can import, and helps accelerating input speed.
The rest may be inferred, and we whenever write a stroke according to sequential write, and the selection that then meets is few more, till retrieving our required Chinese character.
Owing to " falling to pitch pen " phenomenon of user's writing Chinese characters, the individual character stroke is associated dictionary fast and is possessed certain fault-tolerant ability simultaneously.
" the individual character stroke is associated handwriting recognition fast " can be used with various individual characters, the word association in " matts position handwriting recognition ", further increases handwriting input speed.
