List, including missed keys sequence and correct word, such as " csn " -> " can ", with this by missed keys sequence modification be
Correct word.But the limitation of this method is obvious: it can only judge limited known error type, for more one
As neighbouring key errors cannot effectively identify, and easily judge by accident.
Another kind of automatic error correction method is the position by judging screen contact, calculate its arrive each key between away from
From, and the Weighted distance between keystroke sequence and each possible word is calculated with this, finally choose Weighted distance minimum,
Word in dictionary.This method is feasible in theory, but excessively complicated in practice, due to the meter on general portable set
Limited in one's ability, it is difficult to realize.
Content of the invention

Actual this relation or order.Term " inclusion ", "comprising" or any other variant are intended to comprising of nonexcludability, by
This makes a series of process including key elements, method, article or equipment not only comprise these key elements, but also comprises not bright
Other key elements really listed, or for this process, method, article or the intrinsic key element of equipment.
For the purpose of this disclosure, term " keyboard " is generalized definition, including any input unit having and determining region
Part, including but not limited to software keyboard on hardware mechanical keyboard, hardware inductive keyboard, touch screen etc..The present invention's
Embodiment acquiescence illustrates taking the software keyboard on touch screen as a example, but it will be understood by those skilled in the art that the present invention
Mentioned method and system can also be applied to hardware keyboards.
1. basic function and operation
Fig. 1 a describes the keyboard system 100 of an involved in the present invention achievable live keyboard layout and its carrier just
Portable device 101.After button on keyboard 110, its input content is shown in text filed 102 user.Keyboard 110 is
Qwerty layout, contains 26 English alphabets, numeral, symbol and space bar, and each button can represent three characters.Fig. 1 b
Describe the keyboard 120 of another kind of layout, be singly-bound qwerty layout, each button represents a character, can between two keys
There is numbers and symbols.Fig. 1 c describes the keyboard 130 of another kind of layout, is azerty layout, and each button can represent three words
Symbol.Fig. 1 d describes the keyboard 140 of another kind of layout, is 9 key layouts, and each button can represent three to four letters and a number
Word, extensively applies on cell phone keyboard.Fig. 1 e describes a kind of keyboard 150 of User Defined layout, and each button can represent
Three characters, the content of character and order are customized according to use habit by user.
For the purpose of this disclosure, in order to avoid accompanying drawing mark is excessively complicated, hereinafter will with each keyboard layout often
The first row central authorities each key of character mark of individual key.For example, the button 111 in the keyboard upper left corner in Fig. 1 a is identified with key " qw "；
Identify the button 121 in the keyboard upper right corner in Fig. 1 b with key " p "；Identify the button in the keyboard lower left corner in Fig. 1 c with key " wx "；
Identify the button 141 of keyboard last cell in Fig. 1 d with key " wxyz ".When the weight that method definition accordingly occurs in same in figure
During multiple mark, then identified using sequence number and distinguish, to guarantee the uniqueness of this identification method.
It is pointed out that method described in the invention can also apply to other languages in addition to English, other
Keyboard layout, and letter, numeral, the particular content of symbol and position also all can arbitrarily change.
Return to Fig. 1 a, when the key that user clicks on input through keyboard region produces keystroke sequence, system is by the word of candidate
It is shown in candidate region 103, simultaneously can be in the candidate word of text filed middle display acquiescence.When user clicks on candidate word, or press
During lower acknowledgement key when some punctuation marks (such as space bar or), selected word will input in text filed 102.
For example, in fig 1 a, when user's order presses lower key " ty ", key " ui ", during key " er ", system finds corresponding in dictionary
All words of this key sequence, and by its sequencing display in candidate region 103.Due to word " tie ", " turn ",
" tired ", " yield " has highest word frequency, therefore is shown in the page 1 of candidate word list.Wherein " tie " is simultaneously as acquiescence
Candidate word be also shown in text filed interior, and be still unacknowledged text with special format (as underscore) to show it.When with
When space bar is pressed at family, this candidate word is just identified and inputs to text.Because user is in button and indefinite specified every
Concrete character representated by individual button, but by dictionary matching candidate word, therefore it is referred to as " Indistinct Input ".
According to certain embodiments of the present invention, user can also accurately be inputted.For example, with reference to Fig. 1 a, in touch screen
Keyboard 110 on, user can decontrol after pressing and move to left on key " ty ", accurately inputs alphabetical " t "；Key " ui " is pressed simultaneously
Move to right relieving, accurately input alphabetical " i "；Key " er " is pressed and moves to right relieving, accurately input alphabetical " r ".Now system is looked for
To be the word that all " tir " start: " tired ", " tiring ", " tire ", " tirade ".
According to certain embodiments of the present invention, user can be by the symbol below the enter key of slide downward contact or number
Word.For example, with reference to Fig. 1 a, user can move down contact on key " gh ", then input digital " 3 ".So user is no need for
It is switched to special figure pattern or pattern of symbol.
Again for example, with reference to Fig. 1 b, user can input two in key " q " or key " s " or its zone line slide downward contact
Symbol between person "；”.
According to certain embodiments of the present invention, symbol and numeral can also become the part in word.Such as " i ' m ",
" i ' ll ", " let ' s ", " c++ ", " part-time " etc..User can facilitate topotype paste input symbol on same keyboard mode
Number or numeral, without being switched to other pattern of symbol.For example, with reference to Fig. 1 a, on keyboard 110, single quotation marks " ' " in key
On " ui ", user only needs order by lower key " ui ", key " ui ", key " m/ ", and system just can find word " i ' m " and is shown in
In candidate region.
According to certain embodiments of the present invention, when user wants to change keyboard layout, such as from the qwerty layout of Fig. 1 a
Be changed to Fig. 1 d 9 key layout when it is only necessary to pass through a predefined action, you can realize be switched fast.For example, in touch screen
Keyboard on, user rapidly can slide into right-hand member from the left end of keyboard area with finger, then qwerty layout moves right
And remove the right-hand member of screen, and 9 key layouts slip into from the left end of screen, produce coherent dynamic effect.Likewise, user also may be used
To be switched to the singly-bound qwerty layout shown in Fig. 1 b, or the azerty layout shown in Fig. 1 c, or the user shown in Fig. 1 e makes by oneself
Adopted layout.The mode of switching layout can have many kinds: the gesture of user can be detected, it is possible to use a specific button,
Sound control can also be passed through.In this handoff procedure, because the layout of system is separate with dictionary search function, so
Identical lexicon file and software can be used.
On, on less keyboard area, user often presses in input to adjacent key mapping, according to the present invention
A kind of preferred embodiment, this mistake can automatically be corrected according to dictionary.For example, in Figure 1b, when user thinks button " t "
When it is likely that mistakenly having pressed on key " f ".System can letter " r " around search key " f ", " g ", " d ", " v " and according to
Possible correct word is judged in input before family.In an embodiment of the present invention, though the letter of all inputs of user all
It is wrong, system is likely to find out correct word.For example, user input " v ", " i ", " p ", " l ", system can point out
User's candidate word " book ", because " v ", " i ", and " p ", " l " is respectively " b ", " o ", " o ", the neighbouring letter of " k ".It is worth mentioning
, when character position is separated by larger, need to expand the scope (being such as separated by the error correction of two keys) of error correction.But expand error correction model
The side effect enclosed is that candidate word quantity can increase.In order to solve this contradiction, a preferred embodiment of the present invention is error correction model
Enclose and can be adjusted according to user preference.User can be arranged on carry out error correction by alphabetical great scope, for example exist
Error correction in all adjacent letters, or only error correction in the adjacent letter in left and right, or only error correction in neighbouring letter, or
It is separated by error correction between two letters (as " t " and " u "), or not error correction.
According to certain embodiments of the present invention, the related term of candidate word can be rapidly selected.For example, with reference to Fig. 2 a, when
When candidate word 211 " compare " in candidate region, user occurs in " compare " upper slide downward contact, then keyboard area
Related term corresponding to " compare ", " comparing ", " compared ", " compares ", and " comparison ".User
Click on one of related term can be input to text filed.In a lot of language, this related term is very common.
Verb for example in English has much different tenses, and noun has plural form, and a word can have multiple parts of speech etc..This
These word associations can be got up by bright embodiment, thus when user rapidly can extend to other phases from a candidate word
Close word.
According to certain embodiments of the present invention, according to the context relation candidate word of text and phrases prediction can be provided.Example
As with reference to Fig. 2 b, needed after have input " i " before user to input " am ", but pressing in neighbouring key " bn " when inputting " m "
On.Now, system can based on context correlation rule, judge that " i am " is common phrases, therefore adjustment candidate word 221 " am "
Higher than original candidate word " an " priority.In a lot of language, this phrase, specific collocation, custom grammer phenomenon very
Common, the probability of occurrence of a therefore word depends not only on the word frequency of this word, more depends on and this word and context between
The probability of collocation.In this instance, although " an " is a word higher than " am " word frequency, i heel almost always
" am ", rather than " an ".Therefore based on context select suitable word can greatly improve the effectiveness selecting word, and then improve defeated
Enter efficiency.Again for example, with reference to Fig. 2 c, after user input word 231 " look ", in candidate word list automatic Prediction to
" look " forms the candidate word " forward to " of phrase collocation, " at ", " into ", " for ", selects for user.
According to certain embodiments of the present invention, context relation and phrase association can be provided on the basis of related term.
For example, with reference to Fig. 2 d, when user input during related term " looking " of " look ", candidate word region remains to predict
" look " corresponding phrase collocation " forward to ", " at ", " into ", " for " etc..
2. system structure and principle
Fig. 3 describes to be suitable for a kind of general block diagram of portable equipment 300 of the present invention.Input equipment 301, display device
302 are connected with processor 304 by electronic circuit with storage device 303.Input equipment 301 can be keyboard or touch pad；Aobvious
Showing device 302 can be liquid crystal display screen；Storage device 303 can be any memory media, for example random-access memory (ram), only
Rdma read (rom), flash memory (flash), hard disk etc.；Processor 304 can be cpu or dedicated IC chip.A lot of situations
Under, input equipment 301 is likely to synthesize with display device 302, such as touch screen.Storage device 303 can preserve all of software, bag
Containing operating system 311 and keyboard software according to the present invention 310 etc., alternatively, storage device can also include other application journey
Sequence 312, such as text editor etc..
The keyboard system of the present invention is managed by keyboard software 310.Fig. 4 describes a kind of preferred of this keyboard software
System structure 400.This system is mainly by input module 401, layout map module 402, setup module 403, candidate word module
404th, lexicon module 405 and output module 406 form.
Input module 401 is responsible for the input of detection user, the button of such as user, contact action on the touchscreen etc.,
And export to layout map module 402.Layout map module, according to current keyboard layout, user input is mapped to this defeated
Enter corresponding character set, and export to candidate word module 404.Lexicon module 405 is responsible for candidate word module 404 and provides word
Word in allusion quotation.Candidate word module 404 is responsible for for all previous character set generating list entries, and is found out according to list entries
Possible candidate word is simultaneously sorted.Output module 406 is responsible for exporting candidate word in a certain way to equipment, for user's choosing
Select.Setup module 403 stores user and default, for example whether enabling error correction, whether detecting context etc., reflects for layout
Penetrate module 402 to use with candidate word module 404.
Fig. 5 describes keyboard software mastery routine in the main flow 500 completing when user input selects word, possesses following step
Rapid: to wait user input (step 501)；Judge whether to confirm operation (step 502)；If so, in text filed middle input validation
Word, and empty list entries (step 503)；If it is not, generating this in layout map module 402 to input corresponding character set
Close (step 504)；This character set inputting and the character set inputting before are constituted list entries (step 505)；?
Candidate word list is generated, row major level of going forward side by side sorts (step 506) in this module of candidate；Candidate word list (the step that output updates
Rapid 507).
For step 502, input module 401 judges whether this input confirms to operate.Confirm that operation can be by space
Key or confirmation are strong (selected default candidate word), or click directly on candidate word, or by sky after directionkeys choose candidate word
Lattice key or confirm strong, or inputting punctuation mark selectes default candidate word automatically, or other operations of arbitrarily specifying in advance.
For step 504, this input can be mapped as corresponding to by layout map module 402 according to current keyboard layout
Character set.Comprise in this character set to likely correspond to all characters of this input.For example, when user is shown in Fig. 1 a
Qwerty keyboard layout in by lower key " qw " when, character set comprises Indistinct Input character " q " on this key, " w ".And work as and set
Put when enabling error correction, in character set, also can comprise the character in adjacent keys, such as " a ", " s ", " e ".
For step 505, the character set that this inputs can be added in list entries for candidate word module 404.For example,
In qwerty keyboard layout shown in Fig. 1 a, after user's priority presses lower key " ty ", key " ui " and key " er ", list entries bag
Character set containing three inputs: { " t ", " y " }, { " u ", " i " }, { " e ", " r " }.Subsequently, candidate word module 404 can be according to each
Plant possible combination, lexicon module 405 searches out possible candidate word, such as " tie ", " turn " etc..Finally, can basis
Candidate word is sorted by preferred sequence.In some preferred embodiments, may specify that the candidate word of highest priority is default candidate
Word, that is, when user input space or other symbols, automatically confirms that default candidate word is to be input to text filed word.
For step 506, output module 406 candidate word list after updating can be shown on screen, selects for user.
In some embodiments it is possible to default candidate word is shown in text filed interior, and with a kind of special format highlight mark out.
Return to Fig. 4, the implementation method of in the present embodiment each module is described below in detail.
Input module 401 detects the actuation of keys of user, and by the related data record of button each time and exports.Once
The related data of button can be including but not limited to:
User presses the start position of lower contact
User decontrols the final position of contact
The track of user's current collector
The time of staying of user's holding contact
For example, in fig 1 a, when user decontrols by lower key " qw " and after moving to right, the output of input module 401 can comprise
User presses the starting point coordinate of this key and decontrols the terminal point coordinate of this key.
Return to Fig. 4, setup module 403 comprises the various configuration informations related to system operation, including user use preference,
System operating mode etc..For example, user can close error correction.So all would not be repaired by the mistake to adjacent key；
And for example, user can select the rank of error correction: only corrects the mistake of neighbouring button, only correcting the mistake of left and right adjacent key
By mistake, the mistake of periphery adjacent key or mistake (the singly-bound qwerty cloth as shown in Fig. 1 b correcting adjacent two layers button are corrected
" d " can be corrected to by " g " in office, " f ", " h ", " j ").Setup module 403 is optional.
Return to Fig. 4, layout map module 402 has three major functions.
First function of layout map module 402 is to define and be stored with the various layout parameter of different keyboards, such as key
Which character is had on disk, which character is compounded on a key, how accurately character in selection key etc..For example, in figure
In 1a, alphabetical " q ", " w ", and symbol "；" one key " qw " of multiplexing.Fig. 6 then describes a kind of key described in internal memory " qw "
Data structure, wherein can be including (but not limited to) following field:
Position on keyboard layout region for this key and size
Shown character and its relevant position region on this key: " q ", " w ", "；”
The character group of the corresponding input of the different action of user:
ο directly decontrols after clicking on: Indistinct Input " q ", " w ", "；”
Move on ο: Indistinct Input " q ", the patterns of capitalization (" q ", " w ") of " w "
ο moves to left: accurately input " q "
ο moves to right: accurately input " w "
ο upper left is moved: accurately input " q "
ο upper right is moved: accurately input " w "
ο move down accurate input "；”
Accurately the mode of input can have many kinds.A kind of preferably contact according to user moves to judge essence
The really character of input；Multiple characters on this key are launched to select for user after preferably length presses certain input elements by another kind.
For example, in fig 1 a, after user's long keying " as " is more than a Preset Time, this keyboard is just presented as accurate shown in Fig. 7
Input pattern, shows the character group 701 representated by this keys all, selects for user.The initial pattern of Fig. 1 a is returned after having selected.
In Western-European languages, this mode can be used to select accented characters, for example " à á" etc..
It should be noted that each field of this data structure can carry out deleting modification as needed, and do not affect this
The essence of invention.For example, it is possible to increase a field, whether show the picture of amplification after description button above key, be used for
The current input of prompting user；And for example, when position or the size fixation of key, it is convenient to omit position on keyboard area for this key
Size information field.Meanwhile, the different touch action definition of user can also be extension.Definition " user for example can be increased
Length presses this key more than the x second " corresponding input, wherein x can be a configurable value；And for example, " user is double can to increase definition
Hit this key " corresponding input.
As can be seen here, different actuation of keys can correspond to different character sets.
Second function of layout map module 402 is to store all keyboard layouts that may use and switch as needed.
At a time, one and only one is the currently active keyboard layout.Here it is user can see in input through keyboard region
Current keyboard layout.
In a preferred embodiment of the invention, user can switch current keyboard layout using gesture on the touchscreen,
Current keyboard layout can also be switched using certain specific button in hardware keyboards.
3rd function of layout map module 402 is according to current keyboard layout, and being originally inputted of user is mapped as
This input may corresponding character set.A kind of data structure of preferred character set can comprise Indistinct Input character group,
Accurately input character, and error correction character group.
In qwerty layout shown in for example in Fig. 1 a, after user presses lower key " qw " and directly decontrols, this module first from
Obtain the coordinate of contact in input module 401, can determine whether out button on key " qw " according to current arrangements.Because action is a little
Directly decontrol after hitting, according to the topology data of key " qw " can obtain its corresponding Indistinct Input character group be (" q ", " w ", " 1 ",
“；”).Read current error correction and be set to vertical error correction from setup module 403, from current arrangements, then obtain the character of lower section
" a " and " s " is as error correction character.In this button final, the output character collection of layout map module 402 is combined into: Indistinct Input
Character group (" q ", " w ", " 1 ", "；"), accurately input character (empty), error correction input character group (" a ", " s ").
Again for example, in 9 key layouts shown in Fig. 1 d, the corresponding layout information of key " jkl " is as follows:
Position on keyboard layout region for this key and size
Shown character and its relevant position region on this key: " j ", " k ", " l ", digital " 5 ", fullstop ". "
The character of the corresponding input of the different action of user:
ο directly decontrols after clicking on: Indistinct Input " j ", " k ", " l ", " 5 "
ο length is pressed: enters shift pattern (as pinned shift key on computor-keyboard)
ο moves to left: in the normal mode, accurately input " j "；Under shift pattern, accurately input " j "
ο moves to right: in the normal mode, accurately input " l "；Under shift pattern, accurately input " l "
Move on ο: in the normal mode, accurately input " k "；Under shift pattern, accurately input " k "
ο moves down: in the normal mode, accurately input fullstop ". "；Under shift pattern, accurately input " 5 "
When user decontrols after clicking directly on key " jkl ", layout map module 402 obtains the above-mentioned layout of key jkl
Information.Because this action is directly decontroled for after clicking on, therefore Indistinct Input character group is (" j ", " k ", " l ", " 5 ")；Simultaneously
Because the error correction in setup module 403 is set to left and right error correction, therefore error correction character group is the adjacent character group of key " jkl " periphery
(" m ", " i ").
If the user while length presses (or length press then move to left) after moving to left on key " jkl ", long due to comprising one in this button
By action, therefore switch to shift pattern, accurately input character is (" j "), Indistinct Input character group (empty).According to setting mould
The set information of block 403, when accurate input is not space-time, system is without error correction.Therefore error correction character group is also (empty).
As can be seen here, the input of user is converted into the character unrelated with keyboard layout by layout map module 402 effectively
Set, therefore after candidate word module 404 need not change software or data structure according to the difference of layout.Work as keyboard layout
After change, the layout information that layout map module 402 obtains also accordingly changes, and the character set of therefore output also changes therewith
Become.
Because of independent keyboard layout design, keyboard layout can be predefined by cell phone manufacturer completely, or by user
Self-defined, without affecting any systemic-function.For example, user can be corresponding on each key oneself to define the layout of key mapping
Character, and the corresponding character group of action, thus write out the keyboard layout of oneself use habit suitable.Meanwhile, different language
The input method of version can also correspond to and different keyboard layouts.
Return to Fig. 4, this corresponding character set of input is added in list entries candidate word module 404, looks into this
Look for corresponding word in lexicon module 405, and single to candidate according to certain rule (as word frequency, context phrase, related term etc.)
Word carries out prioritization, and candidate word exports output module 406 the most at last.
It will be understood by those skilled in the art that the structure of dictionary for example can be deposited using a variety of implementations
Storage is stored in data base, or with tree.Correspondingly, finding out possible candidate word in dictionary also has a variety of methods.
Following for the feasibility being fully described by the system, illustrate a kind of dictionary that can quickly search word in fact
Existing method, but the present invention is not rely on this method.Word in dictionary is arranged in tree the method, such as Fig. 8
Shown.In each of tree-shaped dictionary node ni-1, ni-2 ... ni-m represents a character, and wherein i represents this node in tree
In depth (i-th layer).I-th character of word positioned at i-th layer of node on behalf.M represents the character sum in this layer,
In English, for example there are 26 letters, then m can be less than 26；If the list being made up of other symbols can be comprised in dictionary
Word, such as don ' t, then m can be more than 26.These nodes are coupled together by path pi-j-1, pi-j-2 ..., pi-j-m, wherein i-
It is ni-j that j represents the connected father node in this path.Reach down to the sequence node of the path institute approach of a certain node from root node,
It is referred to as the character string in this node (or this path).If the character string of a node is one of dictionary word, claim
This node is word node.If a certain paths do not exist, the character string representing this path does not exist in dictionary.Example
If the node corresponding to English word apple is it is simply that order finds node a-p-p-l-e downwards from root node.Wherein the 1st
, at the 1st layer of tree, the node of the 2nd alphabetical p is in the 2nd layer setting for node corresponding to alphabetical a, and the section of the last letter e
Point is word node, and its character string is exactly " apple ".The benefit of this tree be can be quickly found one specific
Alphabetical sequence be whether a word in dictionary, and the corresponding node of this word.
Each word node may correspond to a word object, but the data structure of word object is independently of dictionary knot
Structure.One word object can comprise following information: the statistics word frequency of word, related term, context relation rule, alternate formats
Deng.The statistics word frequency of word can be represented with a numerical value, and such as numeral 1 to 8,8 represents the most frequently used word, and 1 represents the most seldom
Word.Statistics word frequency can become a significant consideration of candidate word prioritization.When not considering other factors, word
Frequency is higher, and the priority of word is higher.
The related term of word refers to the word being associated with this word, the plural form of such as noun, verb different when
State, different parts of speech of this word etc..The related term of such as English word " jump " includes " jumps ", " jumping ",
" jumped " etc..Related words list can be to be realized with pointer mode, and that is, word object can point to its associated other
Word object.The purpose retaining related word information is to facilitate user quickly to select the word of its association from a word.For example when
When user sees that " jump " occurs in candidate word, the action that can be specified in advance by certain is (for example to downslide on word
Dynamic) allow system show all of related term, and therefrom select.
It is related to context environmental that context relation rule contains the common phrase collocation of this word, grammer criterion etc.
Information.For example, the context relation rule of word " look " can comprise common phrase collocation " look at ", " look forward
To ", " look for " etc..And for example, the context relation rule of word " am " can comprise common phrase collocation " i am " etc..Again
As the context relation rule of word " of " can comprise grammatical ruless: " word being followed by should be noun or gerund ".There is this
After a little information, system can pass through the priority of context intelligent decision candidate word.
In the present embodiment, can also come into force mutually during context relation rule is between related term.For example, work as context
When having " look forward to " in correlation rule, even if " looking " occurs can also be associated with " forward in literary composition
To ", because " looking " is the related term of " look ".
Alternate formats are certain forms of expression of this word, and such as " asap " is the contracting of " as soon as possible "
Write form, then if user input " asap ", system can correspond to " as soon as possible " automatically.Therefore
" as soon as possible " is exactly the alternate formats of word object " asap ".And for example, user input " dont " can be entangled automatically
It is being just " don ' t ", because word object " dont " is upper contains alternate formats " don ' t ".Now word object " dont " is actually
It is a kind of index.When a word has alternate formats, alternate formats can preferentially be exported by candidate word module.
Fig. 9 describes a kind of method generating candidate word in the present embodiment, comprises the steps of according to list entries,
Corresponding word object is found as candidate word (step 901) in dictionary；The candidate word mark of character in error correction character group will be comprised
It is designated as error correction candidate word (step 902)；Find the related words list (step 903) corresponding to candidate word；Find candidate word institute right
The alternative form (step 904) answered；Candidate word is carried out prioritization (step 905).
For step 901, candidate word module 404 is by the corresponding character of each button obtaining from layout map module 402
Gather constituted list entries and be combined into possible candidate word.In theory, as long as all character arrangements groups by list entries
Close, and pick out all words existing present in lexicon module, you can constitute candidate word list.But in fact, once press
Key may comprise multiple possible characters, and the character string that multiple button is likely to form will be more.With list entries
Length increases, and if searching dictionary again after the fully intermeshing that will list all character strings, amount of calculation can be very big.Therefore,
A kind of preferred candidate word lookup method of the present invention is the feature using lexicographic tree, is quickly excluded not by retrieving the node of number
Possible character string.For example, if the character set of user's first time button is (" a ", " s "), the character set of second button
It is combined into (" b ", " n "), the character set of third time button is (" t ", " y ", " u "), then the character string combination of three buttons is
2*2*3=12.But if the possible character string of button twice before analysis: " ab ", " an ", " sb ", " sn ", it is possible to find dictionary
In there is not the word (path be sky) of " sb " sequence beginning, therefore only need to consider " ab ", " an ", " sn " and rear three characters
Combination may.Find after analyzing further, in the arrangement of all three character, only " ant ", " any ", " aby " and " abu "
It is likely to become the beginning part of word or word.Therefore actual possible combination is well below 12.With user key-press number of times
Increase, although in theory possible group of character string be combined in increase, profit is in this way, impossible with continuous exclusion
Path, amount of calculation remains at reduced levels.
For step 902, when list entries contain error correction character group, comprise in the candidate word that step 901 is found out
Word after error correction, therefore for the ease of distinguishing it with not corrected ordinary candidate word, is marked as error correction candidate
Word.According to statistics, user presses the probability to key and is higher than the probability pushing the wrong into certain key.Therefore, in follow-up prioritization
In, the priority of error correction candidate word can be less than ordinary candidate word.
For step 904, the alternative form being found can replace original candidate word, adds candidate word list.
For step 905, candidate word searching modul 404 needs to carry out prioritization to candidate word.Impact priority
Factor can comprise: context relation rule, counts word frequency, candidate word length etc..First, context relation rule can be paid the utmost attention to
Then.For example, if having input above " look forward ", the word inputting below is likely to be " to ", rather than with
Its close and same word frequency very high " go ".At this point it is possible to by compare candidate word context relation rule and ought be above
This position above with hereinafter, if it find that certain candidate word and context form phrase collocation, just can be excellent by this candidate word
First level improves.Secondly, system is contemplated that statistics word frequency in this language for the word, and word frequency is higher, then probability of occurrence is bigger, therefore
Priority is higher.Additionally, when candidate word length is equal or close to user key-press number of times, the priority of this word can be enhanced.
If containing error correction character in certain candidate word, its priority can reduce.In a kind of preferred embodiment, final
Priority can calculate after being weighted by many factors and obtain.
Return to Fig. 4, candidate word list is shown to user by output module 406.In certain embodiments of the present invention, for
There is the candidate word of related term, can be marked with special state, and a kind of shortcut of definable allows user enter into this word
The selection pattern of related term.For example, referring to Fig. 2 a, there is an arrow lower section of word " compare ", represents and have found its phase
Close word list.User can enter related term in " compare " upper slide downward contact and select pattern.Some enforcements in the present invention
In example, for error correction candidate word, can be with different format identification (FID)s to show differentiation.
According to one embodiment of the present of invention, after user confirms certain candidate word and is input to text filed, wait
Favored area will show next or multiple words being likely to occur.With reference to Fig. 2 c, after user input " look ", candidate region occurs
Prediction " forward to " to lower word, " at ", " into ", " for ".This is due to the context relation of word object " look "
There are phrase collocation " look forward to ", " look at ", " look into " and " look for " in rule.When user is true
After recognizing candidate word " look ", candidate word module 404 finds out these rules from the context relation rule of this word, and will
" look " part below is shown in candidate region as candidate word.
According to one embodiment of the present of invention, after user confirms certain candidate word and is input to text filed, its
The phrase collocation of related term may also appear in candidate region.With reference to Fig. 2 d, after user input " i ' m looking ", candidate
Also can the prediction " forward to " to lower word, " at ", " into ", " for " in word region.This is due in word object
Have " look " in the related words list of " looking ", and candidate word module can be in related term corresponding context relation imputation
Find out corresponding phrase collocation, and be shown in candidate region.
Figure 10 describes the achievable live keyboard layout for inputting text to electronic equipment designed by the present invention
Method, possesses following steps: wait user input signal (step 1001)；User input signal is turned according to current keyboard layout
It is changed to a character set, described character set comprises the possible corresponding character (step 1002) of described user input；By institute
State character set and add current input sequence (step 1003)；According to described current input sequence, generate candidate word and by preferential
Level sequence (step 1004)；Show described candidate word (step 1005).
3. the switching of layout is adjusted with dynamic
Because of the design of flexible keyboard layout, the keyboard system of the present invention can change keyboard layout and not shadow at any time
Ring method to realize and user's use.
According to certain embodiments of the present invention, user can pass through certain predefined operation, keyboard layout is cut at any time
Change.For example, on the touchscreen, when user is in the quick passing contact of keyboard area, system just can be dynamically by current arrangements
Azerty layout as illustrated in figure 1 c is switched to by qwerty layout as shown in Figure 1a.On the equipment with hardware keyboards,
When user presses certain shortcut, system similarly can be with switching at runtime keyboard layout.
According to certain embodiments of the present invention, in the handoff procedure of keyboard layout, can make to cut by animation effect
Change more natural.For example, referring to Figure 11 a, when the finger keyboard area on the touchscreen of user quickly moves from left to right,
Old keyboard layout smoothly moves from left to right and fades out, and new keyboard layout smoothly moves to the right from screen left end and fades in.
Figure 11 b describes in finger in moving process, and old keyboard layout 1102 is moved out to half, and new keyboard layout 1103 moves into
Situation during half.Figure 11 c describes the situation after new keyboard layout is moved fully into.In the present embodiment, animation effect
Can carry out glibly, and translational speed can determine according to the translational speed of user contact, allow user's sensation keyboard layout be
Moved by user's finger.
Figure 12 describes a kind of method 1200 being switched fast keyboard layout in the present embodiment, comprises the steps of in band
One keyboard layout (step 1201) is shown on the display device of sense of touch；Wait the action that user contact is moved on the touchscreen
(step 1202)；By original keyboard layout along contact moving direction removal screen (step 1203)；By new keyboard layout edge
Contact moving direction moves into screen (step 1204).
The keyboard layout of this method indication not only represents the different layouts of letter, also can broadly refer to for pages content
In certain one page.For example, select on the page, have multipage to select in symbol, user can carry out page turn over operation by this method.
According to certain embodiments of the present invention, user can also dynamically change the layout of keyboard, such as changes the position of button
Put.For example, in Figure 13 a, do not put when user presses " space " space bar 1301, and dragged to a left side for keyboard area
Decontrol after inferior horn, this key has just been arranged at new position 1302 as illustrated in fig. 13b.Keyboard layout can be by accordingly more simultaneously
Newly, for example the numeral " 8 " on space bar becomes for digital " 6 " originally, to keep the seriality of numeral.
Figure 14 describes a kind of method of dynamic change keyboard layout in the present embodiment, comprises the steps of in band sense of touch
Display device on show multiple buttons (step 1401)；Current collector action after detection user presses on a button (walks
Rapid 1402)；Detection user decontrols the position (step 1403) of contact；Adjustment keyboard layout, described button is adjusted to described
Decontrol the position corresponding to contact position, and show the keyboard layout (step 1404) of renewal.
For step 1402, can preset some keys is moveable key, sets some keys as immovable key.
For example, in Figure 13 a, " space " key is moveable key, and other buttons are immovable building.
For step 1404, the position after button adjustment often can be some predefined near relieving contact position
On position.For example, when the position that user decontrols contact falls the region that " space " key is covered in Figure 13 b or distance about
Less than in the range of x pixel when (x can be a predetermined value), after corresponding adjustment position be the screen lower left corner by
Key position.
