Description
Technical field
The invention belongs to word input technology field, be specifically related to a kind of input method and equipment based on button rhythm, so-called button cadence information refers to: press the rule that the moment of key and/or the moment of eject key show.
Background technology
Input method refers to as various symbols being inputted to the coding method that computing machines or other equipment (as mobile phone) adopt., there is multiple different input method different language, country.Most input methods are for Chinese, Korean and Japanese design, because keyboard is to design on behalf of English alphabet in the time of typewriter originally, and the words such as Chinese, Japanese cannot directly be inputted, and must rely on input method coding to input corresponding word.
Chinese character coding input method grew up from the 1980's, went through several stages: individual character input, word input, whole sentence input.Wherein most popular input method is the input method of utilizing the pronunciation of Chinese character to encode, and such as various spelling input methods, phonetic input method etc., as Intelligent ABC spelling input method, Microsoft's spelling input method, purple light spelling input method, search dog spelling input method etc.Wherein, spelling input method needs user to input one by one the phonetic alphabet of Chinese character or word conventionally, then requires user to select Chinese character or the word that will input from the alternative entry of multiple unisonance Chinese characters or word composition.This process of selecting need to expend a large amount of time conventionally, causes the inefficiency of Pinyin Input.
Except spelling input method, the Chinese character coding input method that also information such as structure of with good grounds Chinese character is encoded at present, for example five-stroke input method, stroke input method etc.
These input methods are all that the keyboard-coding sequence in the time inputting corresponds to word or the word that will input by user, for example, in the time that the computer-keyboard by common is inputted " hello " with spelling input method, need to press successively " N ", " I ", " H ", " A ", " O " each key, be that keyboard-coding sequence is " nihao ", then in code database, search all corresponding word candidate item according to keyboard-coding sequence, be alternative Chinese character or word (as " hello "), if while only having a word candidate item, set it as result output; If more than one of word candidate item, presents to user by it with specific DISPLAY ORDER and display mode, selected by input equipment by user, obtain last Output rusults.For example, if keyboard-coding sequence is " zhufu ", can find three word candidate item: " blessing ", " instrucion ", " housewife ".
Along with popularizing of the portable set such as smart mobile phone, panel computer, on portable equipment, input characters becomes a kind of universal phenomenon.But, will be very unfavorable if be equipped with the full keyboard that area occupied is larger on portable equipment, therefore it often adopts numeric keypad, is mainly input as 0～9 these 10 buttons.Like this, keyboard-coding sequence is exactly the sequence being made up of numeral.So, in the time of input characters, first need the keyboard-coding sequence of digital form to correspond to alphabet key coded sequence, and then search and obtain the word candidate item that will export according to alphabet key coded sequence.
In order to improve the word input efficiency that utilizes keypad, for example, in prior art (Chinese invention patent that publication number is CN1834865), exist a kind of directly by the directly input method corresponding with the word candidate item that will export of digital keys coded sequence, according to digital keys coded sequence, for example, all present to user according to certain rule (size of word frequency) according to the corresponding word candidate item of all possible alphabet key coded sequence of its correspondence (phonetic or other coding rules), select rear output by user.
For example, in the time that the CCITT numeric keypad of recommending by CCITT is inputted digital keys coded sequence " 326426 ", its correspondence alphabet key coded sequence " dan'gao ", " dan'gan ", " fang'an ", " fan'gan ", " da'nian ", " dan'han " etc., thus, " 326426 o'clock, what possibility was corresponding was that input characters candidate item comprises " cake, " having the audacity to ", " scheme ", " dislike ", " good year ", " terrified ", " archives ", " pray " etc. to input digital keys coded sequence.
Visible, in the time adopting numeric keypad, often the quantity of word candidate item is huge, often appear at the situation that cannot present all word candidate item on same display interface, at this time, according to the extraneous information relevant to word candidate item, word candidate item is sorted, and show and just seem especially important according to ranking results.Conventional sequencing information comprises word frequency information (the selecteed frequent degree of word candidate item), scene information etc.But these extraneous informations need to be recorded in code database in advance, or upgrade in real time or obtain, therefore needing to take certain computational resource.And, sometimes, only depend on these extraneous informations to be still difficult to obtain good word candidate item ranking results.Therefore,, if can directly produce the extraneous information for guiding the sequence of word candidate item in input process, the saving of the raising to input efficiency and computational resource is produced to favourable effect.

Embodiment
As previously mentioned, existing input method is directly converted to keyboard-coding sequence by user's button operation, and keyboard-coding sequence is analyzed to (for example carrying out cutting), in code database, search word candidate item according to analysis result, and (for example word frequency) will show after the sequence of word candidate item in a certain order.In order to improve the efficiency of input characters in electronic equipment, the present invention has introduced button cadence information in to the sequencer procedure of word candidate item, to obtain better ranking results, improves thus the efficiency of input.
Figure 1A has shown the two states that carries out button on mechanical keyboard.As shown in Figure 1A, in the time that user does not press the each key on keyboard, each key, in " state of upspringing ", does not now produce push button signalling.In the time that user presses certain key it is contacted with the contact of bottom, this key is in " down state ".Conventionally, produce a push button signalling when moment that key contacts with contact, and return and do not produce push button signalling while being added to " upspringing " state from " pressing " state at this key.
Figure 1B has shown the two states of button on touch-screen simulating keyboard.As shown in Figure 1B, different from mechanical keyboard, for the keyboard of being simulated by touch-screen, it can only detect the operating articles such as finger " not contact " and this two states of " contact " screen.Generally, when detecting, touch-screen in the time that " contact " state-transition is " not contact " state, produces a push button signalling.
No matter, for above-mentioned which kind of situation, the speed button cadence information of user in the time of button can be recorded, and this button cadence information will be applied in the sequencer procedure of word candidate item as extra information in the present invention.At this, our definition push key cadence information for: press the rule that the moment of key and/or the moment of eject key show.Here " key " can be both the key of conventional mechanical keyboard, can be also the key on the simulating keyboard of simulating on touch-screen.
The principle that button cadence information can be utilized is: when user is during at button, because user carries out according to coding rule and the word that will input, therefore, the word that user's button rhythm is often thought deeply in brain with user agrees with mutually.For example, user can carry out inputting after subconscious pause the coding of next word in the time having inputted the coding of a word again, this just shows as after producing the push button signalling of some keyboard-codings, until the time interval producing between the push button signalling of next keyboard-coding seems longer than other time interval.If according to a kind of brand-new input method of this principle design, user can be unconscious or between the coding of the different words of input, pauses consciously, just can reach the word that analyzes more efficiently user and may want input, improves the efficiency of inputting.
Therefore, a kind of preferred implementation of the present invention is, the interval duration that button cadence information is continuous key-press.As previously mentioned, for mechanical keyboard, the moment of this generation push button signalling is the moment of pressing key.For touch-screen simulating keyboard, produce the moment of push button signalling for change the moment of " not contact " state into from " contact ".But, for the definition of interval duration, both can be to define according to the moment that produces push button signalling, also can be according to actually pressing key, eject key, between contact screen, these states of contact screen, changing moment does not define, as long as corresponding keyboard or touch-screen support this state to change the measuring ability in moment.
Fig. 1 C and 1D are the schematic diagram that shows two kinds of different interval duration definition.As shown in Figure 1 C, press for the first time key (or contact screen) and press for the second time duration between key (or contact screen) as interval duration T
1,2, press for the second time key (or contact screen) and press for the third time duration between key (or contact screen) as interval duration T
2,3, by that analogy.Be described interval duration be front once press key (or contact screen) and after once press the duration between key (or contact screen).Obviously, this situation is more suitable in mechanical keyboard.Also can be, as shown in Fig. 1 D, to press for the first time eject key (or changing not contact screen into by contact screen) after key and press for the second time duration between key (or changing contact condition into by noncontact) as interval duration T
1,2, press for the second time eject key (or changing not contact screen into by contact screen) after key and press for the third time duration between key (or contact screen) as interval duration T
2,3, by that analogy.Be described interval duration be a front eject key (or changing not contact screen into by contact screen) and after once press the duration between key (or contact screen).Obviously, this situation is more suitable in touch-screen simulating keyboard.T in Fig. 1 D
1, T
2... represent be button be pressed or time the duration that maintains or the duration that keeps in touch state.Certainly, the present invention is not limited to above-mentioned two kinds of modes, and the information of the interval duration between any embodiment button all can be used as button cadence information.
We are shown character vector S at this by keyboard-coding sequence table, and its length is n, and n is natural number, and keyboard-coding sequence S can be expressed as [s
1, s
2..., s
n], wherein s
i(1<i≤n, i is natural number) represents the character of i keyboard-coding in keyboard-coding sequence S.
In addition, we represent the button cadence information of user when the input key coded sequence S with R, have R=D (S), and function D () is the definition rule of button rhythm.Conventionally, button rhythm is relevant to the time point that produces push button signalling, can be expressed as R=y (t
1, t
2..., t
n), t
irepresent to produce keyboard-coding s
ipush button signalling produce time point.
Moreover, we represent the word candidate item corresponding with keyboard-coding sequence S of sequentially arranging with C, there is C=F (S), F () is input method rule, further, F (S) can be expressed as to the combination of coding rule and ordering rule, be C=F (S)=f (K (S)), K () expression obtains the function of all word candidate item corresponding with keyboard-coding sequence S, K (S) represents all word candidate item corresponding with keyboard-coding sequence S, and f () represents this rule that has word candidate item K (S) to sort.
Unlike the prior art, in the present invention, ordering rule f () is also relevant to button rhythm R, therefore has
C＝F(S)＝f(K(S)，R)＝f(K(S)，D(S))。
Can be found out by this formula, in the time that keyboard-coding sequence S is identical and ordering rule f () is constant, the difference of button cadence information R also can make the word candidate item C corresponding from keyboard-coding sequence S different.
A kind of embodiment is, to produce interval duration between each button of keyboard-coding sequence s as button cadence information R, R=D (S)=[t
2-t
1, t
3-t
2..., t
n-t
n-1].But the invention is not restricted to this, any definition for button rhythm R is all in protection scope of the present invention.
And, ordering rule f of the present invention () can use in conjunction with existing sequencing information simultaneously, for example can be in conjunction with the word frequency information of each word candidate item in word candidate K (S), can be expressed as FR (K (S)),, C=f
1(K (S), D (S), FR (K (S))), f
1() also represents the rule that described all word candidate item K (S) are sorted.Certainly, the present invention also can be in conjunction with other sequencing information, such as scene information etc.And, ordering rule f () can be combined with button cadence information and existing sequencing information in various possible modes, for example, can be according to calculating the pinyin syllable of each word candidate item and the matching degree CR of button cadence information (K (S)) in word candidate K (S) according to button cadence information D (S), utilize CR (K (S)) and word frequency information FR's (K (S)) and as the sequence index of K (S), obtain the final word candidate item C sequentially arranging.Be C=f
2(K (S), CR (K (S))+FR (K (S))), f
2() also represents the rule that described all word candidate item K (S) are sorted.
Fig. 2 is the theory diagram of the input method based on button cadence information of the present invention.Fig. 3 is the process flow diagram of the method.Please refer to Fig. 2 and Fig. 3, the input method based on button cadence information of the present invention comprises the steps:
S1, the button of reception user on electronic equipment, sequentially produce keyboard-coding sequence and button cadence information according to user's button.
As previously mentioned, button cadence information refers to repeatedly the rule that the moment of button shows, therefore,, in user key-press, electronic equipment need to detect moment that user presses key and/or eject key (or no contact screen) line item of going forward side by side simultaneously.Existing mechanical keyboard all has to detect conventionally to be pressed and the function of eject key, touch-screen also all has the contact condition of detection and contactless state is changed the function in moment mutually, therefore the present invention can directly use on existing keyboard, and the detected moment is obtained by the correlation function module in electronic equipment and utilize, described functional module can be hardware or software module, will in specific embodiments of the invention, be illustrated.
S2, in a code database of formulating according to described coding rule, search the word candidate item corresponding with described keyboard-coding sequence.
After having produced keyboard-coding sequence by the button that receives user, can carry out and search word candidate item (for example Intelligent ABC input method on traditional computer according to user's instruction, may carry out instruction by inputting a space), also can automatically search input characters candidate item according to acquired keyboard-coding sequence.The input characters candidate item here refers to the word candidate item with keyboard-coding sequences match.
Search the operation of word candidate item normally carries out in a code database.Code database is being stored the corresponding keyboard-coding sequence of different words.For huge code databases such as language coding storehouses, often a keyboard-coding sequence correspondence multiple different word candidate item, and the length of word candidate item is conventionally also inconsistent.For example, word can be both individual character, can be also usual phrase, the idiom etc. of multiword word or multiword.Meanwhile, be not that the keyboard-coding sequence of any combination all stores corresponding word candidate item in code database.
A kind of embodiment is in code database, to search the word candidate item corresponding with the keyboard-coding Sequence of all the first keyboard-codings that comprise keyboard-coding sequence.For a longer keyboard-coding sequence, input method is all since the first keyboard-coding successively matching literal candidate item enter input operation backward.But in code database, the keyboard-coding sequence that comprises the first keyboard-coding may be the keyboard-coding sequence of input, it may be also the front portion of inputted keyboard-coding sequence.Therefore,, in order to contain candidate item corresponding to keyboard-coding sequence all and input, the present invention is preferably the corresponding word candidate item of keyboard-coding Sequence of the first keyboard-coding of searching all keyboard-coding sequences that comprise input in code database.For example, when the keyboard-coding sequence of input is while be " fangan ", the present invention searches and " f ", " fa ", " fan ", " fang ", word candidate item that " fanga " " fangan " is corresponding, and their are unified to sort.
S3, in the time that this word candidate item is more than one, consider that described button cadence information sorts to each word candidate item, then presents to user by described electronic equipment.
This step is committed step of the present invention.The button cadence information obtaining in step S1 is utilized herein.Conventionally, obtaining after multiple word candidate item, need to be shown to user with a kind of sortord, and before the word candidate item that tool possibility is selected as to final input characters comes, so that user watches, or be shown in easy selecteed position (situation of touch-screen) in screen, so that user selects rear input.Existing existing various ways sorts to the word candidate item of input characters, for example, by statistics in advance, the conventional degree of word is sorted, or utilize the method for self study, and the sequence number of user being inputted to the word that the frequency is maximum shifts to an earlier date.
The present invention is on this basis, and button cadence information is considered as a sequence index.Taking Pinyin Input Chinese written language as example, the phonetic that coding rule is Chinese character, a corresponding pinyin syllable of Chinese character.Suppose that user is in the time of button, and the interval duration between each button corresponding to same syllable is shorter, and interval duration between different syllables is longer, so, can sort to described word candidate item according to the matching degree of the pinyin syllable of button cadence information and each word candidate item.
A kind of embodiment is, as long as find the longest position of duration, interval in a keyboard-coding sequence, and the spaced-apart locations of location estimation syllable according to this.Like this, just the sequence sequence number that meets this syllable spaced-apart locations in word candidate item can be shifted to an earlier date, make the sequence of word candidate item more be tending towards user's actual need.
For example, for common full keyboard, when the keyboard-coding sequence of input is " fangan ", it is made up of 6 keyboard-codings, and word candidate item comprises that its phonetic is " scheme " of Fang'An, also comprises that phonetic is " dislike " of " Fan ' Gan ".In the time not considering button cadence information, " scheme " and " dislike " can be according to conventional word frequency for sorting.In the time considering button cadence information, can obtain the longest place, position of interval duration of button, if it is between the 3rd button and the 4th button, input characters is more likely " dislike ", if it is between the 4th button and the 5th button, input characters is more likely " scheme ".
The introducing of this button cadence information, for adopting, input method or the system of numeric keypad are more favourable.Because for numeric keypad, the number of combinations of keyboard-coding is less, word candidate item corresponding to keyboard-coding sequence is huger, now, by conventional word frequency sequence still can not realize well, sequence accurately.
In order to realize the sequence of above-mentioned button cadence information, need to carry out record to the word separation information of each word candidate item in code database.For the encode Chinese characters for computer storehouse of Pinyin Input, the syllable separation information of basic word candidate item should be carried out to record, so that its word spaced-apart locations reflecting with the button cadence information that obtains compares, so that the sequence number of the word candidate item mutually meeting is shifted to an earlier date.For example, for word candidate item " Xi'an ", its keyboard-coding sequence is " xian ", or " 9426 " of numeric keypad, according to the phonetic of this word candidate item " xi ' an ", known its word is separated position between the 2nd and the 3rd, like this, as a kind of example, can represent this position by numeral " 2 ".Now, if the Chang position, interval of four buttons of input " xian " or " 9426 " is between the 1st and the 2nd, or between the 3rd and the 4th, be not judged as and mate with the separation position of this word candidate item recording in code database, before the sequence number in " Xi'an " not being adjusted; If between the 2nd and the 3rd, being judged as with the separation position of this word candidate item recording in code database, Chang position, interval mates, before the sequence number in " Xi'an " is adjusted.
But, it should be noted in the discussion above that the word separation position in the word candidate item in the present invention can be more than one, for example, for four word Chinese idioms, position separated in its word just three.Thus, the button cadence information in the present invention can be also several the longest positions of button interval.That is to say, can calculate between button every front n the longest position according to the moment of pressing or upspring n>=1.
S4, according to the sequence of described word candidate item, automatically generate input results, or receive user for the selection of described word candidate item, using the result of selecting as input results.
This step is the step that obtains input results, can adopt any mode of the prior art to realize.For example, after having obtained the final sequence of word candidate item, can select to obtain last input results according to user, also can, in the time that word candidate item only has the preferential selectance (the selecteed possibility going out according to word frequency and button tempo calculation) of or word candidate item to be greater than certain threshold value, in the situation that selecting without user, directly produce input results.
In order to continue inputting of next word, the keyboard-coding section corresponding with described input results deleted from described keyboard-coding sequence, and remaining keyboard-coding sequence is judged, if also comprise keyboard-coding in described keyboard-coding sequence, return to step S2 and continue to select user's input characters candidate item, if there is no keyboard-coding, return to next step input of step S1 wait user.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in further detail.
Fig. 4 is the FB(flow block) of the input method based on button cadence information of one embodiment of the present of invention.This embodiment uses spelling input method input Chinese character on numeric keypad.As shown in the figure, first, what user was continuous presses " 3 ", " 2 ", " 6 ", " 4 ", " 2 ", " 6 " each key, produces thus keyboard-coding sequence 326426.Meanwhile, obtain the time point of the push button signalling that produces each button, calculate the interval duration (unit second) between each button, obtain:
t(s
2)-t(s
1)＝0.2
t(s
3)-t(s
2)＝0.3
t(s
4)-t(s
3)＝0.25
t(s
5)-t(s
4)＝0.5
t(s
6)-t(s
5)＝0.2
Then, in a Pinyin coding storehouse, search all keyboard-coding sequences that comprise the first keyboard-coding " 3 ", " 3, 32, 326, 3264, 326426 ", wherein, phonetic corresponding to " 3 " is " e ", phonetic corresponding to " 32 " is " da " and " fa ", phonetic corresponding to " 326 " is " dao, dan and fan ", phonetic corresponding to " 326426 " is " da'nian, da'niao, dan ' gao, dan ' gan, fan ' gan, dan'han, dao ' gao, dao'hao, fan'hao, dan'hao, fang ' an, dang ' an ", therefore, can comprise by the word candidate item of tabling look-up corresponding with each coded sequence and " starving, dislike, pretty young woman, Russia, goose, send out, greatly, beat, valve, method, arrive, meal, load, indulge in, but, when, side, put, room, party, cake, dare, scheme, dislike, good year, terrified, archives, pray " etc.
On the other hand, the present invention carries out segmentation according to button cadence information to keyboard-coding sequence, according to the matching degree of the separation mode of the pinyin syllable of this segmented mode and each word candidate item, described word candidate item is sorted.In this embodiment, button cadence information is the interval duration between button, can obtain t (s
5)-t (s
4) be the longest interval duration in the duration of all intervals, that is to say, the time interval between the 4th button and the 5th button is the longest, like this, can by described keystroke sequence, " 326426 " carry out segmentation with this maximum time interval, i.e. " 3264-26 ", "-" represents segmentation position, or, also can represent according to the number of characters of each section i.e. " 4-2 " type segmentation.
In this embodiment, also can obtain the position of second largest interval duration, according to above-mentioned interval duration, interval duration between known the 2nd keyboard-coding and the 3rd keyboard-coding is second largest interval duration, equally, the position of second largest interval duration and largest interval duration, all as segmentation position, can be obtained to " 32-64-26 ", i.e. " 2-2-2 " segmentation.
Similarly, other embodiments of the present invention also can obtain according to the 3rd, the 4th interval duration more segmented modes of keyboard-coding, do not repeat them here.
According to one embodiment of the present invention, described each word candidate item sorts from big to small according to sequence desired value, and, make the sequence desired value increase of the word candidate item that segmented mode mates with the separation mode of the pinyin syllable of word candidate item.Like this, just the cadence information of introducing in the present invention is introduced as an index of sequence.
And, more preferably, in the time there is multiple segmented mode for keyboard-coding sequence, to each segmented mode by it matching degree setting priority with the separation mode of pinyin syllable, and make the sequence desired value of the word candidate item that the segmented mode higher with priority mate increase manyly.
Priority is for example calculated according to the hop count of segmentation, by " 4-2 " section segmentation such two-part segmented mode be arranged in syllogic segmented mode " 2-2-2 " before.In the sortord for alternative formula after the priority of this segmented mode can be applied to.
Preferably, can determine according to the proportionate relationship between the interval duration of keyboard-coding sequence the priority of segmented mode.
A kind of embodiment is to calculate equispaced duration t
a, in the time that the difference between the second long interval duration and this mean value is less than poor between itself and the first interval duration, the priority of segmented mode of having utilized this second interval duration is made as lower than the priority of segmented mode of not utilizing this second interval duration.For example, in the present embodiment, equispaced duration t
ait was 0.29 (second), the second long interval duration was 0.3 (second), largest interval duration was 0.5 (second), the difference of the second interval duration and equispaced duration is 0.01 second, be less than differing from 0.2 second of itself and largest interval duration, therefore, the priority of " 2-2-2 " is made as to the priority lower than " 4-2 ".
If there are a greater variety of segmented modes, also can adopt the method that segmented mode priority is similarly set.For example, for the 3rd interval duration, can calculate the poor of the difference of itself and equispaced duration and itself and the second interval duration, in the time that its value more approaches mean value, adopt the priority of the 3rd interval duration to establish lowlyer.But adopting equispaced duration is one embodiment of the present invention, those skilled in the art may adopt other existing classification to carry out calculating priority level.
In the above-described embodiments, obtaining after each word candidate item corresponding with keyboard-coding sequence " 326426 ", according to the syllable spaced-apart locations of the phonetic of each word candidate item and the registration of the segmented mode of the keyboard-coding sequence obtaining according to button cadence information, each word candidate item is being sorted.In this embodiment, the segmented mode that priority is the highest is " 4-2 ", and therefore, the word candidate item " scheme ", " archives " that are also " 4-2 " by the number of characters of pinyin syllable rank the first.Be the word candidate item of " 2-2-2 " owing to there is no syllable, other all word candidate item are processed not according to button cadence information.In this embodiment, for the identical word candidate item of button cadence information matching degree, still adopt the sortord of prior art to carry out, can adopt word frequency information to sort.The pinyin syllable of described each word candidate item is separated mode and can be stored in described code database.
In other embodiments of the invention, button cadence information and existing sortord can combine the index as sequence.For example, be the limit priority of " 4-2 " for segmented mode, can make and a rhythm desired value A
1, the rest may be inferred, and segmented mode is the less preferred level of " 2-2-2 ", makes its corresponding rhythm desired value A
2, the rhythm desired value that there is no the word candidate item of segmentation is 0.When to each word candidate item sequence, the word frequency value of each word candidate item and its rhythm desired value are added as the index of sequence.
