Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In Chinese character input process, in order to reduce the complexity of input, improve input efficiency, the embodiment of the invention discloses a kind of input method, comprising: detect the continuous slide on keyboard area, obtain continuous sliding trace; According to preset track identification rule, identify the filtercondition matching with described continuous sliding trace; Described continuous sliding trace is identified, from dictionary, matched at least one candidate item undetermined of the track characteristic that meets continuous sliding trace; Show the candidate item that meets filtercondition in candidate item undetermined.The method can reduce the repetition rate of coding, improve input efficiency.
Below in conjunction with accompanying drawing, a kind of input method of the present invention is described in detail, referring to Fig. 1, show the schematic flow sheet of an embodiment of a kind of input method of the present invention, the input method of the present embodiment is applied to the electronic equipment that is provided with arbitrarily keyboard area and possesses words input function, as be provided with touch-screen mobile phone, PDA etc.The input method of the present embodiment comprises:
Step 101: detect the continuous slide on keyboard area, obtain continuous sliding trace.
Wherein, this keyboard area can be the dummy keyboard on touch-screen, or the dummy keyboard that produces by projection of electronic equipment, also can be physical keyboard.On this keyboard area, show alphabet key, can also have other character keys etc.
It should be noted that, the region that continuous slide can be detected that this keyboard area is interpreted as presetting, therefore this keyboard area not only comprises the region that is provided with button on keyboard, can also comprise the region that is not provided with button.In the time of this keyboard area correspondent entity keyboard, this keyboard area comprises the white space that the keypad of button is set in physical keyboard and button is not set.In the time of the corresponding dummy keyboard of this keyboard area, as the keyboard demonstrating on touch-screen, this keyboard area can be understood as button viewing area and apart from the region in the certain limit of button viewing area.Thereby in the time there is continuous slide on keyboard area, even if sliding trace exceeds key zone continuously, system also can detect the continuous sliding trace that marks key zone, and by key zone and the track that marks key zone make as a whole continuous sliding trace.
In the time that this keyboard area is dummy keyboard, user can by finger or felt pen in the enterprising line slip of this keyboard area, this electronic equipment can get the sliding trace of the contact such as finger or felt pen on dummy keyboard, also can on dummy keyboard, click the modes such as slip by the equipment such as such as mouse and carry out input character.And specifically obtain the mode of the slip continuous path on this keyboard area, can on keyboard area, in sliding process, change the sliding trace of determining contact by the magnitude of voltage of each coordinate points on touch-screen by contact; Also can absorb the continuous sliding trace of user on dummy keyboard by first-class image acquisition unit by the shooting on electronic equipment, determine the track characteristic of continuous sliding trace.
In the time that this keyboard area is physical keyboard, user can by finger or felt pen in the enterprising line slip of keyboard area, determine the continuous sliding trace of the continuous slide in this physical keyboard by the electromagnetic field inducing unit being arranged in physical keyboard, or absorb the continuous sliding trace of user's input by the image capture unit on electronic equipment.
As, when the electronic equipment that has a touch-screen when utilization carries out words input, meeting display keyboard region on the touch-screen of electronic equipment, user can be by finger or the keyboard area respective keys enterprising line slip of felt pen on the touch-screen of this electronic equipment, to realize character input.
Slidably inputing continuously in method, user is utilizing finger or felt pen etc. to carry out slide on keyboard area, like this along with the slide of finger or the contact such as felt pen will form a continuous sliding trace, this continuous sliding trace has comprised contact and has drawn successively the content such as each character string and stroke via line of contact on the keyboard area of warp.
Indication slide of the present invention refers to a kind of gesture operation, and does not require that must there be physical contact in input equipment and keyboard layout; Described continuous sliding trace reality is corresponding to the change in location sequence of series of points, sliding trace both can have explicit outward appearance interface, draw the lines of the position line formation of warp as gesture, also can there is no explicit outward appearance, as only have the continuous variation of mouse pointer position.
Step 102: according to preset track identification rule, identify the filtercondition matching with described continuous sliding trace.
Unlike the prior art, in the present invention in the time getting continuous sliding trace, track identification rule that need to be built-in according to electronic equipment, need to identify the filtercondition that this continuous sliding trace comprises, candidate item is screened according to this filtercondition so that follow-up, to reduce the repetition rate of coding of words.
Wherein, according to the difference of the continuous input trajectory getting, and the difference of preset track identification rule, this continuous input trajectory is identified to the filtercondition obtaining also may be different.
Step 103: described continuous sliding trace is identified, matched at least one candidate item undetermined of the track characteristic that meets described continuous sliding trace from dictionary.
Wherein, the track characteristic of sliding trace comprises the alphabetical sequence of warp that this continuous sliding trace is drawn, the key mapping of each alphabetical sequence, track starting point, the track attributes such as track flex point and final on trajectory continuously.
From dictionary, matching the candidate item mode undetermined matching with the track characteristic of this continuous sliding trace can identify and obtain candidate item operation undetermined continuous sliding trace according to existing.Whether the coupling of the track characteristic of identifying comprises is filtered gesture part, according to matching algorithm and different.
Step 104: show the candidate item that meets described filtercondition in described candidate item undetermined.
After matching candidate item undetermined and obtain filtercondition from dictionary, need to screen this candidate item undetermined according to this filtercondition, obtain meeting in this candidate item undetermined the candidate item of filtercondition, and the candidate item filtering out is shown, reduce like this repetition rate of coding of the candidate item showing, and then be convenient to user candidate item is selected, thereby improve input efficiency.
It should be noted that, the sequence of operation of step 102 and step 103 can be exchanged, and also can carry out simultaneously.
Wherein, according to preset track identification rule, the mode that identifies the filtercondition matching with continuous sliding trace has multiple, optional, wherein mode is: according to a preset track identification rule, identify the filtration gesture input trajectory comprising in described continuous sliding trace; According to preset filtration gesture matched rule, determine the corresponding filtercondition of described filtration gesture input trajectory.First this kind of mode determined and belonged to the one section of track that filters gesture input trajectory from this continuous sliding trace, and then filter gesture matched rule, matches the filtercondition that this filtration gesture input trajectory mates.Wherein, a part of track that this gesture input trajectory is described continuous input trajectory or all track.
According to preset track identification rule, identify when slidably inputing continuously the filtration gesture input trajectory comprising in track, can also slidably input continuously and track, identify character string input trajectory from this.According to the difference of preset track identification rule, the character string input trajectory identifying from continuous input trajectory also may be different.
As, when in preset track identification rule, regulation is using whole continuous sliding trace during all as character string input trajectory, using continuous whole piece sliding trace rule as character string input trajectory, and character string input trajectory is identified, from dictionary, match and meet the coded string matching with this character string input trajectory, and obtain corresponding candidate item undetermined.Simultaneously, to according in this preset track identification rule, from continuous sliding trace, identify and filter gesture identification track, and according to preset filtration gesture matched rule, determine the corresponding filtercondition of this filtration gesture input trajectory, according to this filtercondition, candidate item undetermined is screened.
In addition, in preset track identification rule can also be: according to default rule, from this continuous sliding trace, isolate character string input trajectory and filter gesture input trajectory.Concrete, can be in this continuous sliding trace, to determine to filter gesture identification feature locations, according to this filtration gesture identification feature locations, this continuous sliding trace is divided into character string input trajectory and filters gesture input trajectory.Wherein, this character string input trajectory can slidably input the continuous sliding trace except this filtration gesture input trajectory in track continuously for this; The continuous input trajectory of this character string also can have the partial continuous sliding trace overlapping with this filtration gesture input trajectory.
Further, continuous sliding trace is being identified, the mode that matches at least one candidate item undetermined of the track characteristic that meets described continuous sliding trace from dictionary also can have multiple.Wherein a kind of mode is: the string encoding input trajectory in continuous sliding trace is identified, matched at least one candidate item undetermined of the track characteristic that meets string encoding input trajectory from dictionary.
Another kind is identified continuous sliding trace, at least one the candidate item mode undetermined that matches the track characteristic that meets described continuous sliding trace from dictionary is: the string encoding input trajectory in continuous sliding trace is identified, match at least one first candidate item undetermined of the track characteristic that meets string encoding input trajectory from dictionary time, the continuous sliding trace of whole piece is identified, and from dictionary, matched at least one second candidate item undetermined of the track characteristic that meets the continuous sliding trace of whole piece.Using the set of the first candidate item undetermined and the second candidate item undetermined as candidate item undetermined, and the filtercondition of determining in follow-up foundation screens all candidate item undetermined.
Referring to Fig. 2, show the schematic flow sheet of a kind of another embodiment of input method of the present invention, the present embodiment be embodiment illustrated in fig. 1 in a concrete implementation, the present embodiment comprises:
Step 201: detect the continuous slide on keyboard area, obtain continuous sliding trace.
Step 202: according to preset track identification rule, identify character string input trajectory and filter gesture input trajectory from described continuous sliding trace.
General, when getting after continuous sliding trace, directly identify coded string according to this continuous sliding trace, and from dictionary, match the candidate item corresponding with this continuous sliding trace.But in the present invention, in the sliding process of contact, not only can comprise the character string input trajectory that coded string is corresponding, can also comprise and filter gesture input trajectory.
In the present invention in the time getting continuous sliding trace, need to be according to preset track rule of detachment, determine the filtration gesture identification feature locations in continuous sliding trace, and from this continuous sliding trace, isolate character string input trajectory and filter gesture input trajectory in conjunction with the filtration gesture identification feature locations of determining.
Wherein, can determine according to this character string input trajectory the coded string that user is to be entered, and then obtain user's at least one Chinese character candidate item to be entered.Can determine the screening conditions to Chinese character candidate item according to this filtration gesture input trajectory, and then candidate item be screened to the candidate item that is met requirement, and then reduce the repetition rate of coding, improve input efficiency.
Step 203: described character string input trajectory is identified, identified at least one candidate item undetermined of the track characteristic that meets described character string input trajectory from dictionary.
Character string input trajectory is identified, from dictionary, matched the multiple undetermined candidate item corresponding with this character string input trajectory.Character string input trajectory is identified and then mated the process of candidate item undetermined from dictionary, continuous input trajectory is identified to obtain candidate list identical with existing.Different is, in the present embodiment after determining the undetermined candidate item corresponding with this character string input trajectory, can't directly candidate item undetermined be shown, determine filtercondition and need further foundation to be filtered to gesture input trajectory, and then from candidate item undetermined, select to meet the candidate item of filtercondition.
Step 204: according to preset filtration gesture matched rule, determine the corresponding filtercondition of described filtration gesture input trajectory.
Filter filtercondition corresponding to gesture input trajectory in order to determine, in electronic equipment, be built-in with and filter gesture matched rule, according to this filtration gesture matched rule, this filtration gesture input trajectory is analyzed to coupling, obtain the filtercondition corresponding with this filtration gesture matched rule.
Step 205: show the candidate item that meets described filtercondition in described candidate item undetermined.
Determine after filtercondition corresponding to the filtration gesture of user input, can from candidate item undetermined, select the candidate item that meets this filtercondition, and show that this meets the candidate item of filtercondition, and then reduce the repetition rate of coding, the quantity of the candidate item showing obviously reduces, and user can select more easily the candidate item that needs screen output from the candidate item showing.
Any one embodiment above, the corresponding relation between filtration gesture input trajectory and filtercondition is relevant with preset filtration gesture matched rule.But after preset filtration gesture matched rule is determined, a certain filtration gesture input trajectory only can a corresponding filtercondition.
Preset filtration gesture matched rule can be the matched rule filtering between gesture and input tone, and then determine according to this matched rule filtering between gesture and input tone, can determine tone corresponding to this filtration gesture input trajectory, using the corresponding tone of this filtration gesture input trajectory as filtercondition.From candidate item undetermined, there is the candidate item of the tone phase same tone corresponding with this filtration gesture input trajectory.
Filter after gesture input trajectory when determining, according to track characteristics such as the track starting point of this filtration gesture input trajectory, final on trajectory, trajectory directions, this filtration gesture input trajectory is analyzed, thereby determined the corresponding tone of this filtration gesture input trajectory.
To be the process of determining the corresponding tone that filters gesture input trajectory in order can more clearly understanding in the present invention, to be described with an example below, referring to Fig. 3, show a kind of a kind of corresponding relation filtering between gesture and tone.
As shown in the figure, corresponding relation is:
One sound, laterally from left to right with dextrosinistral continuous input trajectory;
Two sound, the continuous input trajectory from lower-left to upper right;
Three sound, the continuous input trajectory from upper right to lower-left;
The four tones of standard Chinese pronunciation, from left to bottom right or from lower right to the continuous input trajectory of upper left.
Like this, when being that continuous horizontal line from left to right or is from right to left (in practical operation to filtering gesture input trajectory, this filtration gesture input trajectory is approximate this horizontal line that is parallel to) analyze after identification, determine after this filtration gesture input trajectory that with preset tone be that corresponding track matches, determining the tone that this filtration gesture input trajectory is corresponding is, and then from candidate item undetermined, selects and meet the candidate item that tone is.And meet the input trajectory from lower-left to upper right when filtering gesture input trajectory, the tone input trajectory of this filtration gesture input trajectory and this three sound matches, and then to determine the tone that this filtration gesture input trajectory is corresponding be three sound.
For example, character string input trajectory is identified, the coded string identifying is " wo ", and candidate item undetermined corresponding to " wo " comprises that " nest " " I " " hold " " crouching " etc., be three sound and identify tone corresponding to filtration gesture input trajectory, can only from candidate item undetermined, select " I ", and then simplify input operation process, improve input efficiency.
Certainly, the corresponding relation between preset filtration gesture input trajectory and tone can also have other types, is not limited to the corresponding relation shown in Fig. 3.
In addition, preset filtration gesture matched rule can be the matched rule between preset filtration gesture and entering stroke.And then, according to the matched rule between this preset filtration gesture and entering stroke, determine and filter entering stroke corresponding to gesture input trajectory, using this entering stroke as filtercondition; And further inquire about the entering stroke storehouse of candidate item undetermined, from candidate item undetermined, determine that in the entering stroke that forms candidate item undetermined, input sequence is positioned at the candidate item that last entering stroke is identical with the entering stroke of determining.Because each Chinese character forms by multiple strokes, can be by a corresponding entering stroke that comprises candidate item to be selected in filtration gesture input trajectory in order to reduce repetition rate of coding user, after identifying multiple candidate item undetermined according to character string input rule, determine last entering stroke that each candidate item undetermined is corresponding, if last entering stroke of certain candidate item undetermined entering stroke corresponding with this filtration gesture input trajectory is identical, this candidate item undetermined is shown as candidate item.
The specific implementation of the matched rule between filtration gesture and entering stroke that this is preset has multiple, referring to Fig. 4, shows a kind of corresponding relation filtering between gesture input trajectory and entering stroke of the application.In the figure, horizontal input trajectory from left to right or from right to left is corresponding with entering stroke " horizontal stroke "; Vertical input trajectory from top to bottom " is erected " corresponding with entering stroke; Will be from upper right side to lower left continuous input trajectory corresponding with entering stroke " slash ", the corresponding relation of other entering strokes and filtration gesture input trajectory also as shown in Figure 4, describe no longer one by one, therefore, filter after gesture input trajectory when determining, this filtration gesture input trajectory is mated with the track in Fig. 4, thereby determine and filter entering stroke corresponding to input gesture, and then this entering stroke is filtered as filtercondition.
For example, character string input trajectory is identified, the coded string identifying is " wo ", and candidate item undetermined corresponding to " wo " comprises that " nest " " I " " hold " " crouching " etc., and entering stroke corresponding to the filtration gesture input trajectory identifying is " horizontal stroke ", in above candidate item undetermined, meeting the candidate item that finishing touch entering stroke is " horizontal stroke " is " holding ", can " hold " and show.
Preset track identification rule may be different according to actual needs in this application, corresponding, and the mode that identifies character string input trajectory and filter gesture input trajectory from continuous sliding trace also has multiple different mode.Wherein mode is: determine a phonetic last letter for last stroke of warp of this continuous sliding trace, using this, last phonetic last letter of drawing warp is as filtering gesture identification feature locations; Using the phonetic last letter of this last stroke of warp in this continuous sliding trace continuous sliding trace afterwards as filtering gesture input trajectory, and using the continuous sliding trace except this filtration gesture input trajectory in this continuous sliding trace as character string input trajectory.Certainly, also can only go out to filter input trajectory according to this rule from slidably inputing continuously track identification, and using continuous whole piece sliding trace as character string input trajectory.
Wherein, phonetic last letter is to determine according to the Chinese phonetic alphabet rule letter that is positioned at tail end in phonetic transcriptions of Chinese characters, and this phonetic last letter comprises single vowel, and single vowel comprises alphabetical a, alphabetical e, alphabetical i, alphabetical o, alphabetical u, alphabetical v.In addition, this phonetic last letter also comprises alphabetical n, alphabetical g and alphabetical r.General, in this continuous sliding trace, only comprise that is filtered a gesture input trajectory, can draw using input starting point to this last continuous sliding trace between the phonetic last letter of warp as character string input trajectory, and by this continuous sliding trace getting, the continuous sliding trace after the phonetic last letter of this last stroke of warp is as filtering gesture input trajectory.
For example, be a kind ofly on keyboard area, to slidably input continuously track referring to Fig. 5, in this Fig. 5, be described as an example of input " I " example, contact is slidably inputing continuously track as shown in curve in figure on keyboard area, wherein, solid line part represents character string input trajectory, gesture input trajectory is filtered in dotted portion representative, because the tone of " I " is three sound, therefore this filtration gesture input trajectory corresponding for tone be the input trajectory (i.e. input trajectory from upper right to lower-left, can with reference to shown in Fig. 3) of three sound.Electronic equipment gets continuous sliding trace, the character string sequence that this continuous sliding trace is drawn warp is successively " wertyuiok ", this continuous sliding trace is identified, determining the phonetic last letter that this continuous sliding trace finally draws warp is " o ", this phonetic last letter " o " is located as filtering gesture identification feature locations, and then to determine this input starting point be that character string input trajectory is in figure shown in solid line to the continuous sliding trace between this phonetic last letter " o ", this character string input trajectory is drawn successively through " wertyuio ", by this character string sequence is identified, can determine qualified coded string, suppose that qualified coded string only has " wo ", and candidate item undetermined corresponding to " wo " comprises " I ", " hold ", " crouch " " ", " nest " etc., and the part that this phonetic last letter " o " is arrived to continuous sliding trace tail end is as filtering gesture input trajectory, according to the corresponding relation between preset filtration gesture and tone, determining the tone that this filtration gesture input trajectory is corresponding is three sound, can from candidate item undetermined, select that to meet tone be that the candidate item of three sound is shown.
The another kind of mode that identifies character string input trajectory and filter gesture input trajectory from continuous sliding trace is: using the continuous sliding trace in from input starting point to designated length in continuous sliding trace as filtering gesture input trajectory, and continuous sliding trace outside filtering gesture input trajectory is as character string input trajectory.Wherein, this designated length can be set as required, as can be, using the input starting point of contact to the length between next alphabet key as designated length, also set the total length of two alphabet keys as designated length.This kind of recognition method, using a part of track of continuous sliding trace front end as filtering gesture input trajectory, and will filter gesture input trajectory sliding trace afterwards as character string input trajectory, thereby in once slidably inputing process, complete character string input and tone and filtered two operations, simplified input operation process.
For example, referring to Fig. 6, for the continuous sliding trace of the another kind on keyboard area, in the present embodiment taking input " bar " as example, because the tone of " bar " is, therefore corresponding filtration gesture input trajectory when first user can input tone and be in the time slidably inputing continuously, then directly carry out the input of character string " ba ", as shown in the figure, in figure, dotted portion is for filtering gesture input trajectory, the length of this dotted portion is to be greater than the length of a character keys and to be less than two character lengths, and the length of this dotted portion is within the scope of default designated length, solid line part is character string input trajectory.
In the time that electronic equipment gets this continuous sliding trace, the input starting point of determining contact is to the continuous sliding trace within the scope of designated length, and using the continuous sliding trace of determining as filtering gesture input trajectory, and this filtration gesture input terminal continuous sliding trace is afterwards as character string input trajectory, this character string input trajectory is drawn successively through character " bvcsa ", track characteristic to character string input trajectory is identified, obtain coded string for " ba ", and according to filtering the corresponding relation of gesture with input tone, determining this filtration gesture input trajectory is that tone is corresponding track (adopting in this example corresponding relation as shown in Figure 2), therefore, from " ba " corresponding " ", " eight ", " father ", " pull out " in candidate item undetermined such as " bar ", the candidate item undetermined of selecting tone and being is as the candidate item showing, thereby demonstrate the candidate item of a sound such as " bar " and " eight ".
The another kind of mode that identifies character string input trajectory and filtration gesture input trajectory from continuous sliding trace is: the Hand Gesture Segmentation district in keyboard area is set in advance, wherein, this Hand Gesture Segmentation district can be certain specified button or certain setting key disk area, and concrete can set according to actual needs.In the process of carrying out sliding continuously in contact on keyboard area, if need to distinguish character string input trajectory and filter gesture input trajectory, cutting apart rule according to default track can be by continuous sliding trace, and the continuous sliding trace before drawing through described Hand Gesture Segmentation district is as filtering gesture input trajectory; Or, by continuous sliding trace, draw continuous sliding trace through described Hand Gesture Segmentation district after as filtration gesture input trajectory.
It should be noted that, several modes that identify above filtration gesture input trajectory from continuous sliding trace can mutually combine, the mode of multiple identification gesture input trajectory is combined, and to be applicable to coded string corresponding to continuous input trajectory be the phonetic transcriptions of Chinese characters of words or short sentence, in this kind of situation, from a continuous input trajectory, can obtain two or more pieces and filter gesture input trajectory, also can be for multiple and filtration gesture input trajectory is identified to the filtercondition obtaining.
With preset track identification rule, following two kinds of modes are integrated as to example: the phonetic last letter of last stroke of warp of this continuous sliding trace will be determined, using this, last phonetic last letter of drawing warp is as filtering gesture identification feature locations, and the continuous sliding trace after the phonetic last letter of this last stroke of warp in this continuous sliding trace is as filtering gesture input trajectory; Using in continuous sliding trace from input starting point to the continuous sliding trace in designated length as filtering gesture input trajectory.Like this, article one, in continuous input trajectory, input starting point can be for being identified as a continuous gesture input trajectory to the continuous input trajectory of designated length, and the phonetic last letter that continuous sliding trace is finally drawn warp can be identified as another filtration gesture input trajectory to the track of input terminal.So continuous input trajectory can identify two filterconditions, and the general phrase also forming for multiple Chinese characters of the corresponding candidate item undetermined identifying from continuous input trajectory, for a candidate item undetermined, Article 1 can be filtered to the filtercondition of filtercondition first Chinese character in this candidate item undetermined that gesture input trajectory is corresponding, and Article 2 is filtered to the filtercondition of filtercondition Chinese character at end in this candidate item undetermined that gesture input trajectory is corresponding.
For example, the candidate item undetermined that certain continuous input trajectory is identified comprises: " me ", " assurance ", " pull out and hold " etc., filter gesture input trajectory and identify two sections according to method of the present invention from this continuous input trajectory, article one, filter gesture input trajectory and be input starting point to the continuous path in designated length, if this filtration gesture input trajectory is identified, identifying corresponding tone is three sound, the candidate item undetermined that is three sound according to the tone that should select first Chinese character from candidate item undetermined obtains " me " and " assurance ", establish the phonetic last letter that identifies last delimitation from this continuous input trajectory to filtration gesture input trajectory corresponding to track end simultaneously, and establishing the tone that this filtration gesture input trajectory is identified is the four tones of standard Chinese pronunciation, the candidate item undetermined that the phonetic of selecting last Chinese character according to this tone from candidate item undetermined is the four tones of standard Chinese pronunciation, meet first Chinese character in candidate item undetermined is three sound simultaneously, and the candidate item undetermined that last Chinese character is the four tones of standard Chinese pronunciation is " assurance ", " assurance " can be shown, thereby reduce the repetition rate of coding and improved input efficiency.
