Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
Embodiment one
The present embodiment is for inputting the Chinese phonetic alphabet and complete Chinese character input, during actual use, naturally it is also possible to it inputs
The character of the various characters such as phonetic alphabet, English alphabet, the various characters or coded combination that only need to have regulation to put in order is equal
Can, input object is simultaneously not especially limited.
According to Chinese phonetic alphabet layout rule, i.e., according to the Scheme for the Chinese Phonetic Alphabet of national official, can follow in phonetic at it
His phonetic (such as initial or other letters) subsequent character set is { a, e, g, h, i, m, n, o, r, u, ü }, and wherein ü is being calculated
It is indicated in machine with v.In the specific implementation, this character set can be adjusted according to required character set, can also be incited somebody to action
All Chinese phonetic alphabets are as character set.For example, m can only be followed after h as the non-initial of phonetic, and the corresponding Chinese character of hm
It seldom and is of little use, it is possible to non-initial character collection is not added in m.Therefore, it in the present embodiment, can follow behind other characters
Character set be preferably { a, e, g, h, i, n, o, r, u, v }.
These character set are divided into the sub- character set of several groups by the present embodiment, and each group of sub- character set may include one or more
A character.For example, it can be grouped according to unambiguity principle, the character of no ambiguous conflict is individually divided into one
Group, such as character g, u, r points are one group, then character gur is grouping character, and equally, character a is individually divided into one group.It establishes each
The sub- character set of group is associated with a fixed-direction.The sub- character set of multiple groups is then associated with multiple directions correspondingly and fixedly.
After sliding in one direction on input interface, this direction will be identified, and filter out associated sub- character set accordingly.?
When carrying out above-mentioned layout, the quantity in direction can be adjusted variation according to actual needs, but be limited to user's operation
With the precision of identification, it is usually no more than 8.
The each character that can be followed after the other characters pass corresponding with six direction of the present embodiment is denoted in Fig. 1
System.In Fig. 1, in character input process, reference axis is established as coordinate origin in plan-position where inputting initial character, and
Determine the six direction of upper and lower, upper left, lower-left, upper right, bottom right, it should be noted that direction here can refer to a tool
The direction of body angle is also possible to the direction of a field angle, such as in Fig. 3, the upper right where character a, the upper right
Direction include with X-axis it is positive and out of X-axis 60 ° of compositions of positive rotation counterclockwise angular ranges (i.e. angle is (0 ° -60 °))
It is considered as upper right.In the present embodiment, above-mentioned six direction each means the direction of a field angle.And it is set in character input
Stage up and down, upper left, lower-left, upper right, bottom right slide and respectively represent input character g or u or r, h or n or v in effective range,
I, o, a, e slide effective range namely refer to the angle model that line of travel is fallen into where a direction in setting six direction
In enclosing.
As shown in Figures 1 to 7, a kind of input method based on sliding trajectory identification obtains first Chinese that user clicks
The initial position of phonetic alphabet, i.e. the lead-in parent signal of acquisition user input, to obtain initial position, and with lead-in
Female position is initial position, and identifies the sliding trajectory that user slides since initial position.It should be noted that
If character set does not include all Chinese characters (such as initial m is not in character set), in order to guarantee that initial can be with
Input can input initial using click mode；If character set includes all Chinese characters, initial can not be with point
The mode of hitting inputs, can be using input is slided, i.e. the first segment curved section of sliding trajectory represents initial.Such case only needs
The initial position of user is obtained, and identifies the sliding trajectory that user slides since initial position.
Sliding trajectory includes line of travel and running length, and line of travel can be judged by the slope of curve of point,
The slope of curve of the point that is to say the tangent slope of the point, therefore line of travel can also be sentenced by the tangential direction of point
It is disconnected, identify which sub- character set of the passed through character set of sliding trajectory to identify word according to line of travel and running length
Symbol, wherein first Chinese phonetic alphabet that user clicks is as initial.The cunning slided since initial position according to user
Line direction and running length, identify sliding trajectory by first sub- character set correspond to character set a, e, g, h, i, n, o,
R, u, v } which of sub- character set, when identify sliding trajectory by first sub- character set after, with first sub- word
Symbol collection continues to judge line of travel and running length as starting point, identifies that second that sliding trajectory passes through sub- character set is corresponding
To the sub- character set of which of character set { a, e, g, h, i, n, o, r, u, v }, and so on, until a sliding trajectory is passed through
The sub- character set crossed all identifies.
As shown in Fig. 2, inputting initial n, and the cunning of user is identified using the position of initial n as initial position
Row track (i.e. curve OCDEFG) identifies user's since initial position O point (O point is the input for indicating to complete initial n)
Line of travel and running length, it can be found that the slope of curve at any point of curved section (OC) all (indicates packet at section [a, b]
Include boundary value a and b, naturally it is also possible to not include boundary value a and b) slide in range and to upper right, the straight line in Fig. 2
The slope of OA and OB is in section [a, b] range, and section [a, b] fairly falls in the sector where Fig. 3 neutron character set gur
Two side l in region1And l6The slope section that is constituted as boundary value of slope.Corresponding one 60 ° of each character set in Fig. 3
Angular range.The slope area of the region sub- character set gur is all fallen within according to the slope of curve at any point of (OC) of curve
Between, thus curved section (OC) represent user wish input sub- character set gur in one, and sub- character set gur only have letter u
It can follow after initial n, therefore curved section (OC) represents user and wishes to input alphabetical u, that is, identifies sliding trajectory
(OCDEFG) first letter (initial is not denoted as first character) passed through, therefore each curved section represents in character set
A determining sub- character set.
According to mathematics geometric knowledge, it is known that (can that is to say the corresponding straight line of the slope of curve of curve point by this
The tangent line of point) be unique confirmable, therefore can also according to the corresponding tangent line of the curved segments and the angle value of X-axis forward direction come
Judge the sub- character set that sliding trajectory is passed through, for example, in Fig. 2 the slope of straight line OA and both tangent line OA and the angle of X-axis be can
With what is uniquely converted, therefore both characters substantial equivalence is judged according to the slope of curve or angle, here to according to angle
To judge not introduce specifically.
After first sub- character set is identified from sliding trajectory, continue to judge subsequent sliding trajectory institute by identical method
The sub- character set passed through.It can be found that the slope of curve of C point is equal to the boundary value to the corresponding slope section of upper right, therefore
C point is a diacritical point, can distinguish sliding trajectory by diacritical point C and slide by and be identified first sub- character
Collection, subsequent sliding trajectory is the range into second sub- character set, therefore diacritical point refers to that the slope of curve of the point is equal to
The boundary value of slope range where a certain sub- character set, the anterioposterior curve section of diacritical point respectively represent in character set in character set
A sub- character set, i.e., between starting point and adjacent diacritical point or between two adjacent diacritical points or terminal and adjacent
Sliding trajectory between diacritical point constitutes one section of curved section, and a curved section corresponds to a sub- character set in character set.With area
Branch C judges line of travel and running length as starting point, to judge that curved section (CD) is the son that user needs to input
Character set a, curved section (DE) are the sub- character set e that user needs to input, and curved section (EF) is the sub- character set hnv of user's input
In character h or n or v, curved section (FG) be user input sub- character set o.Here C point, D point, E point, F point is all to discriminate between
Point, the last period curve of diacritical point and latter section of curve respectively correspond a sub- character set.Thus by sliding trajectory (OCDEFG)
All sub- character set passed through identify, after all sub- character set are identified, reject in sub- character set with initial character
The character of legal combining characters cannot be formed.Here legal combining characters cannot be formed refer to and be identified on sliding trajectory
A character or multiple characters cannot follow after initial character.It should be noted that legal combining characters might not
It is complete legitimate characters sequence (such as complete pinyin sequence), for example, initial is x, is identified word on sliding trajectory
I and o is accorded with, character i and o can successively follow one legal combining characters " xio " of formation after initial x, although legal
Combining characters " xio " are not a complete legitimate characters sequences, but pass through association, it is known that the legal combining characters
" xio " can also form a complete legitimate characters " xiong ".Therefore, in the present embodiment, legal combining characters include root
According to the complete of character arrangement table rule (such as Chinese phonetic alphabet layout rule or English alphabet layout rule or other character arrangement tables rule)
Whole character string, partially complete character string, partially complete character string refers to be added in the tail portion of the partially complete character string
Complete character string is capable of forming after adding several characters.After the multiple characters being identified are followed in initial character be by
The character that sliding trajectory sequencing passes through successively follows after initial character.Such as legal combining characters " nuan ", character u
It first passes through, so pass through after character a in character u, therefore character a is followed after character u after initial character n,
The legal combining characters formed before character u without will lead to character a, and so on.Determining character is followed in a word to exist
The rule of the sequence of positions of combining characters and the character homologous thread section determined in the sequence of positions of sliding trajectory.Group character gur
Only have character u and character v that can follow after character n in group character hnv.Therefore, this sliding trajectory slided
(OCDEFG) being capable of forming complete legal combining characters has " nu, na, nuan, nun, nan, ne, nen, nv, nao ", when
So also there are incomplete legal combining characters " nua ".
The corresponding track effective percentage of legal combining characters is calculated separately out, track effective percentage refers to legal combining characters
In the sum of the length of curve of each character homologous thread section in addition to initial character curve corresponding with entire sliding trajectory it is long
Spend the ratio of summation.For example, legal combining characters " nuan ", the length of curve of the corresponding curved section of character u (OC) is 3, word
The length of curve for according with the corresponding curved section (CD) of a is 7, and the length of curve of the corresponding curved section of character n (EF) is 3, therefore legal
Combining characters " nuan " track effective percentage be (3+7+3)/(3+7+2+3+7)=59.09% similarly can calculate conjunction
The track effective percentage of the combining characters " nu " of method is 3/ (3+7+2+3+7)=13.64%, the track of legal combining characters " na "
Effective percentage is 7/ (3+7+2+3+7)=31.82%, and the track effective percentage of legal combining characters " nun " is (3+3)/(3+7+2+
3+7)=27.27, the track effective percentage of legal combining characters " nan " is (7+3)/(3+7+2+3+7)=45.45%, legal
Combining characters " ne " track effective percentage be 2/ (3+7+2+3+7)=9.09%, the track of legal combining characters " nen " has
Efficiency is (2+3)/(3+7+2+3+7)=22.73%, and the track effective percentage of legal combining characters " nv " is 3/ (3+7+2+3+
7)=13.64%, the track effective percentage of legal combining characters " nao " is (7+7)/(3+7+2+3+7)=63.64%.It calculates
After the track of all legal combining characters is efficient out, select the corresponding legal combining characters of track effective percentage highest as
The target character for needing to input, the corresponding Chinese character of target character are the target characters for needing to input, for selection by the user, Yong Hucong
It is selected in target characters and as final input character.For example, the track effective percentage highest of legal combining characters " nao ",
Therefore, legal combining characters " nao " are target character, and corresponding Chinese character is target characters (such as makes a noise, brain, scratches ...), are used
Therefrom target characters are as input character at family, to complete to input.
It should be noted that the track effective percentage of the legal combining characters on one sliding trajectory of calculating both can be first
Entire sliding trajectory (i.e. until user stops sliding) is identified and calculates track effective percentage again, can also be identified with real-time synchronization
Sliding trajectory and track are efficient, and the efficient result in the track that the two obtains is consistent.
For example, after identifying the complete sliding trajectory of user (OCDEFG), then started and by line of travel with starting point O point
Calculate curve (OCDEFG) if on any point or the slope of curve done, when calculate to C point the slope of curve, it can be found that
The slope of curve at any point all falls within the slope section of the region sub- character set gur, therefore curved section on curved section (OC)
(OC) represent user wish input sub- character set gur in a character.Similarly, it can be found that it is any one on curved section (CD)
The slope of curve of point all falls within the slope section of the region sub- character set a, the slope of curve at any point on curved section (DE)
The slope section of the region sub- character set e is all fallen within, the slope of curve at any point all falls within word word on curved section (EF)
Symbol collects the slope section of the region hnv, and the slope of curve at any point all falls within the location sub- character set o on curved section (FG)
The slope section in domain.The track for finally calculating each legal combining characters again is efficient.
It can also be synchronized during sliding and calculate track effective percentage in real time, when user is when sliding curved section (OC)
Having calculated that the track of legal combining characters " nu " is efficient, user does not terminate to slide and be to continue with and slide at this time,
New character is identified in the range of the subsequent line of travel slided falls in the sub- character set of certain in character set, then is continued
It is efficient to calculate track, therefore during sliding, then calculating pair occurs whenever sliding by and being identified new character
The track answered is efficient.It is consistent using the result calculated again after result calculated when sliding and whole slided.
Practical study discovery, usual user is in the direction of the subsequent sliding trajectory of initial skid (such as first segment curved section)
More acurrate namely subsequent sliding trajectory can more be slided according to the direction of sub- character set.In response to this, it is excellent to provide first
The corresponding running length of the first segment curved section of sliding trajectory can be expanded several times in the first prioritization scheme by change scheme
Track effective percentage is calculated after (such as 10 times or 20 times) again.For example, the running length of the curved section (OC) of the first segment in Fig. 2 is
3, after expanding 10 times, the running length of curved section is 30.In this way, the track effective percentage of legal combining characters " nu " is 30/ (30
+ 7+2+3+7)=61.22%, the track effective percentage of legal combining characters " nuan " be (30+7+3)/(30+7+2+3+7)=
81.63%, other legal combining characters are also similar to be calculated, and is learnt by calculating, and track is efficient highest legal at this time
Combining characters be " nuan ", therefore legal " nuan " be used as candidate characters.
As to whether into the first prioritization scheme, then it can be with according to whether receiving the first optimization signal, the first optimization be believed
It number can be controlled by one key (can be physical button or virtual key) of setting, when clicking the key, then it represents that produce
Raw first optimization signal.It can certainly be judged whether to automatically generate the first optimization letter according to the previous input habit of user
Number, such as the input habit previous according to user, judge due to the first segment curved section of user's sliding trajectory length of curve not
It is enough, and cause the track effective percentage comprising the corresponding combining characters of first segment curved section relatively low, and calculated output is tied
Fruit is not the expected results of user's true intention, and user deletes and re-enters.And the song of the first segment curved section after re-entering
Line length is elongated, when primary or stipulated number occurs in such case, the first optimization signal can be automatically generated, to carry out excellent
Change.When receiving the first optimization signal, then enter the first prioritization scheme.
When the sliding trajectory of user passes through two identical characters, as shown in figure 4, first segment curved section (OC) slides
By sub- character set gur, final stage curved section (GH) is also slided by sub- character set gur.And in order to distinguish initial character and
The legal combining characters " nu " and initial character and final stage curve of the corresponding sub- character set gur composition of one section of curved section (OC)
The legal combining characters " nu " of the corresponding sub- character set gur composition of section (GH), are denoted as " nu is 2. " for " nu " that the latter forms.
According to determining character in the sequence of positions of combining characters and the character homologous thread section determined in sliding trajectory
This rule of sequence of positions, the character u in legitimate characters " nuan " formed here are the corresponding character u of first segment curved section,
Rather than the corresponding character u of final stage curved section.
Practical discovery, the running length of the usually last sliding trajectory (usually corresponding to final stage curved section) of user compared with
It is short, even if the second effective length is not achieved in the running length of final stage curved section at this time, if but final stage curved section cunning
The angle of the line of travel (i.e. second from the bottom section of curved section) of line direction and latter section of curved section is more than that predetermined angle is (such as default
Angle is set as 60 degree), it that is to say two of composition of the diacritical point on the curved section of two sections of front and back between last two sections of curved sections
The angle of tangent line is more than predetermined angle, then expands several times to the running length of final stage curved section and (such as expand 10
Times).Such as tangent line of the diacritical point G in Fig. 4 on final stage curved section (GH) is GG2, it is (i.e. second from the bottom in the last period
Section) tangent line on curved section (FG) be the angle of GG1, tangent line GG1 and tangent line GG2 is more than predetermined angle, although then GH at this time
Running length is shorter, even less than the second effective length, then sliding trajectory GH, which is still considered as, effectively slides, and according to sliding trajectory GH
Line of travel identify the corresponding character gur of the curved section (GH).
And it may in order to guarantee still to be constituted by more acurrate identification in the case where the curved section that user finally slides is shorter
Legal combining characters, can by the running length of final stage curved section expand several times, such as expand 10 times.Such as scheme
In 4, the running length of final stage curved section (GH) is 2, after expanding 10 times, the rail of the legal combining characters " nu is 2. " of composition
Mark effective percentage is 20/ (3+7+2+3+7+20)=47.62%.Certainly, the running length of first segment curved section and final stage are bent
The running length of line segment can also expand several times simultaneously, such as the running length of first segment curved section (OC) expands 20 times, most
The running length of latter section of curved section (GH) also expands 20 times, then the track effective percentage of combining characters legal at this time " nu is 2. " is
40/ (60+7+2+3+7+40)=33.61%.
As shown in fig. 7, obtaining English character (English word) using English input, initial is also possible to defeated by sliding
Enter, since English inputs same letter, it is specified that when one section of curve segment length for corresponding to a sub- character set in the presence of needs are continuous
Often reach the second effective length primary, such case that once inputs the sub- character set, the first segment curved section identified is corresponding
Sub- character set as initial, the corresponding sub- character set of subsequent curved section is followed constitutes legal combination after initial
Character.Such as in Fig. 7, the legitimate characters " able " of formation are English word, and initial a is the word that first segment curved section identifies
Accord with the character concentrated.
Judgement can certainly be compared with the second effective length to the length of curve of all curved sections of sliding trajectory,
Only when the length of curve of curved section is more than or equal to the second effective length, being just considered as the curved section is effectively to slide, i.e., only has
Otherwise legal combining characters could be formed as the character in legal combining characters by imitating the corresponding character of curved section slided
In do not consider to slide corresponding character in vain.In Fig. 7, the length of curve of the second segment curved section of sub- character set " def " is represented
It is 0.5, is less than preset second effective length (such as being set as 2), then second segment curved section is considered as slides in vain, according to word
It accords with layout rule and does not consider the curved section when judgement forms legal combining characters.Similarly, the of sub- character set " ghi " is represented
The length of curve of four sections of curved sections is 0.5, is not also taken into account.Therefore, the legal group that the sliding trajectory in Fig. 7 is capable of forming
Closing character includes that " the track effective percentage of able, bake, bald, bale, cake, calf ", each legal combining characters are (3+
3+3)/(3+0.5+3+0.5+3)=90%.
Certainly, the second effective length can be identical with the value of the first effective length, can not also be identical.
In the present embodiment, the running length of one section of curved section also refers to the length of curve of the curved section, and the two concept is identical.
For the ease of user in taxiing procedures, intuitively know clearly that line of travel represents corresponding character, also with
During family is slided, input instruction figure, input instruction figure packet are shown in corresponding position (such as upper left corner of input interface)
Include the grouping situation of display character set and the direction of every group of character association.
If the character and initial character that are identified on a complete sliding trajectory of user's input can only constitute a conjunction
The combining characters of method, then the track that can not calculate legal combining characters at this time is efficient, by unique legal combined characters
Accord with the candidate characters inputted as needs.As shown in figure 5, after user inputs initial character q, identified sub- character on sliding trajectory
Collection has gur and sub- character set a, but can only constitute unique legal combining characters " qu ", therefore by legal combining characters
" qu " corresponding Chinese character is as candidate input character.
Sometimes in user's taxiing procedures, (refer to except first segment curved section and final stage are bent in certain intermediate regions of sliding
Sliding trajectory except line segment) it is possible to not be the desired character for needing to input of user.As shown in fig. 6, user inputs lead-in
A sliding trajectory is slided out after symbol h, which includes three curved sections, and first curved section is identified sub- character set
A, second curved section are identified sub- character set gur, the last one curved section is identified sub- character set i.User is intended that
It is expected that legal combining characters " hai " is inputted, and due to sliding to sub- character from sub- character set a after sliding the sub- character set a of input
Collect i, the line of travel of sliding trajectory usually has the line of travel of one section of curved section (i.e. second curved section) that can fall into sub- word
Sub- character set gur is identified in the range of symbol collection gur.It, can be by sub- character set gur institute in order to avoid such case generation
The running length of second segment curved section reduce several times, such as the 1/2 of former running length is reduced, so as to by the curve
The track effective percentage for the legal combining characters that character in section is constituted with initial character becomes smaller.For example, not to second segment curve
In the case that the running length of section reduces, the track effective percentage of legal combining characters " ha " is 3/ (3+5+4)=25%, legal
The track effective percentage of combining characters " hu " be 5/ (3+5+4)=41.67%, the track of legal combining characters " hai " is effective
Rate is 3+4/ (3+5+4)=58.33%, the track effective percentage of legal combining characters " hui " be (5+4)/(3+5+4)=
75%；And the running length to second segment curved section is reduced in the case of the 1/2 of original running length, then legal combining characters
The track effective percentage of " ha " is 3/ (3+2.5+4)=31.58%, and the track effective percentage of legal combining characters " hu " is 2.5/ (3
+ 2.5+4)=26.32%, the track effective percentage of legal combining characters " hai " is (3+4)/(3+2.5+4)=73.68%, is closed
The track effective percentage of the combining characters " hui " of method is (2.5+4)/(3+2.5+4)=68.42%.Obtained track effective percentage is most
High result it is expected the true intention of input closer to user.
In order to reduce several times to the length of curve for meeting the corresponding curved section of preset condition, such as in Fig. 6
The length of curve of second segment curved section reduces 0.5 times, can optimize signal according to third to control, believe when receiving third optimization
Number, then several times are reduced to the length of curve for meeting the corresponding curved section of preset condition.The preset condition refers to current curves
Section is not the first segment curved section or final stage curved section of sliding trajectory, and the slope of the corresponding character direction of current curves section
The boundary value of range is respectively by the oblique of one of slope range boundary value of upper character corresponding direction and next character corresponding direction
One of rate range boundary value is constituted.Third optimization signal can also be generated by key.
Embodiment two
As shown in figure 8, embodiment as character using Chinese phonetic alphabet or English phonetic alphabet first is that carry out sliding input
, the difference is that, the present embodiment carries out sliding input as character using stroke, naturally it is also possible to use with embodiment one
Other character inputs.It carries out sliding input using Chinese stroke as character, Chinese stroke can be divided into several strokes, only need
By Chinese stroke as character set, and establish being associated with for each Chinese stroke and direction.Such as according to national official's " Modern Chinese
General words table " regulation Chinese shape code is divided into five stroke classes, naturally it is also possible to according to other regular partitions at other
Stroke, such as eight kinds are divided into according to " word eight treating observances forever ".In the present embodiment, as shown in figure 8, by Chinese stroke be divided into including point,
Horizontal, vertical, folding skims five strokes, adds an asterisk wildcard, so that character set includes that point, cross, folding, slash and asterisk wildcard are total
Six characters.Fig. 8 shows by stroke, as character, inputting Chinese in sliding way " side ", the track effective percentage of Chinese " side " is (6+
3+4+4)/(6+3+4+4)=100%.
Embodiment three
As shown in figure 9, the difference is that, the curve segment length of one sliding trajectory of embodiment does not consider most with embodiment one
Low length, that is, no matter length identifies corresponding character to the length of curve of the curved section identified, in addition, embodiment one is arranged
Character set in character refer to can become legitimate characters in character, such as can be Chinese pinyin, English alphabet, in
Style of writing picture etc., but do not include the spcial character of number, symbol, functional operator etc., these spcial characters can not form conjunction
Character in method character.In order to input these spcial characters, in the present embodiment, increase spcial character in character set, and will
Spcial character is associated with one by one with fixed-direction, includes increasing " deletion " functional operator, and " word selection " feature operation in Fig. 9
Symbol, " word selection " function is i.e. from the legal combining characters that the corresponding character of curved section that current sliding trajectory includes can form
Select a combining characters as input character.When the line of travel of the curved section of sliding trajectory falls into " deletion " or " word selection "
In direction scope, then delete operation can be carried out or enter word selection to operate, and to the song of the corresponding curved section of these spcial characters
Line length be arranged the first effective length, when the corresponding curved section of spcial character length of curve be equal to the first effective length, just view
It is effectively to slide for this section of sliding trajectory, is otherwise considered as and invalid accidentally slides.And the value of the first effective length can be according to reality
Situation is adjusted.As shown in figure 9, the line of travel of third section curved section (i.e. curve 34 in figure) falls into the direction model of " word selection "
In enclosing, to identify that third section curved section needs to carry out word selection, then further judge that the curve of third section curved section is long
Whether degree is more than or equal to the first effective length (such as effective length is set as 0.5), if meeting condition, third section curved section generation
Table needs to carry out word selection really, and otherwise third section curved section is considered as the curved section slided in vain.When third section curved section is considered as nothing
After imitating the curved section slided, during the track for calculating legitimate characters is efficient, the total length of corresponding sliding trajectory is also needed
The length of curve of invalid curved section is rejected, calculation amount can be reduced in this way.Such as the Chinese pinyin " guan " of legitimate characters,
Its track effective percentage is (5+3+4)/(5+3+0.5+4)=96%, and the total length of sliding trajectory is not by third section curved section
Length of curve take into account, reduce calculation amount.
When the curved section identified is to need to carry out word selection, such as third section curved section (curve 34) and the 6th in Fig. 9
Section curved section (curve 67) needs to carry out word selection.For the such case for needing to carry out word selection, then executed by step in detail below:
The position for needing to carry out the curved section of word selection is obtained, is judged before first segment curved section to word selection homologous thread section
Can the corresponding character of all curved sections of one section of curved section follow after initial character, and obtain determining character.It will obtain
Determination character and initial character constitute legal combining characters, determining character combining characters sequence of positions and determine
Sequence of positions of the character homologous thread section in sliding trajectory.
If initial character is first to write music the corresponding character of line segment, judge with second segment curved section to word selection homologous thread
Can the corresponding character of all curved sections of the last period curved section of section follow after initial character, and obtain determining character,
And then obtain legal combining characters.
After obtaining legal combining characters, the track for calculating each combining characters is efficient, it is noted that rail at this time
The length of curve summation of all curved sections of the efficient sliding trajectory of mark refers to first segment curved section to word selection homologous thread section
The last period curved section all curved sections length of curve summation or second segment curved section to word selection homologous thread section before
The summation of the length of curve of all curved sections of one section of curved section.
And using the efficient highest combining characters in track as candidate characters, and candidate characters may be corresponding with multiple meanings
Character, and select from the character of multiple meanings a specific character as input character, to complete to input.Such as scheme
In 9, since the length of curve of third section curved section is less than the first effective length, do not enter word selection function.Final stage is bent
The length of curve of line segment is greater than the first effective length and enters word selection function, calculates the track of each legal combining characters at this time
Effective percentage, the efficient corresponding legal combining characters in highest track are " guan ", and combining characters " guan " be corresponding with it is more
The character (including pipe, tank, pass, used etc.) of a meaning, to breathe out selection region, selection region shows that the combining characters are corresponding
The character of multiple meanings, and the selection signal of user is received, using the character of the corresponding concrete meaning of selection signal as input word
Symbol, such as user select " to manage " as input character, to complete to input from " pipe, pass, is used to tank ".
The present embodiment is inputted for Chinese pinyin, is also possible to for Chinese stroke input, such as by calculating
The effectively corresponding combining characters in obtained highest track are " one by one | " (combining characters that i.e. horizontal, horizontal, vertical three strokes are constituted),
And the character of at least corresponding three meanings of the combining characters: dry, in, Chu.It can certainly be other character inputs, to need
It to be selected from the character of concrete meaning.
After the character that user breathes out selection region and chooses concrete meaning completes input, this target word is also implied that
Symbol slides end of input.
The present invention identifies all characters of user's sliding trajectory, so that obtaining can be all legal with initial character composition
Combining characters, and the track for calculating all legal combining characters is efficient, selects the efficient highest legal combination in track
Character slides the track of input without limiting each character to complete the input of character as the candidate characters that needs input
Length.
