For example, referring to Figure 1A, a kind of schematic diagram of dummy keyboard of the embodiment of the present invention is shown, which can be with Referred to as nine grids keyboard or 9 key boards mainly may include 9 virtual keys.

In another example B referring to Fig.1, shows the schematic diagram of another dummy keyboard of the embodiment of the present invention, the dummy keyboard It is properly termed as full keyboard or 26 key boards, a typical full keyboard or 26 key boards can be qwerty keyboard, mainly can be with Including 26 virtual keys.

Certainly, above-mentioned dummy keyboard is intended only as example, in implementing the embodiments of the present invention, can set according to the actual situation Other dummy keyboards are set, this embodiment of the present invention is not limited.In addition, other than above-mentioned dummy keyboard, art technology Personnel can also use other dummy keyboards according to actual needs, also be not limited to this embodiment of the present invention.

Moreover, user when dummy keyboard inputs, can use the objects such as finger or stylus in the touch of mobile terminal It is slided position in screen where dummy keyboard.It, can be with so in order to determine that user slides the selected virtual key of input The multiple tracing points slided on the virtual keyboard, and the capture sequencing based on the tracing point are captured, with arbitrary continuation two Directed line segment in a tracing point building sliding trajectory.

In embodiments of the present invention, the track slided on the virtual keyboard can be captured using any methods availalbe or equipment Point is not limited this embodiment of the present invention.For example, for virtual laser keyboard (Virtual Laser Keyboard), It can be by induction reflection light to carry out tracing point capture；For capacitance touch screen, then can be obtained by periodic samples Tracing point；Etc..

After capturing the tracing point slided on the virtual keyboard, then it can be constructed in sliding trajectory by tracing point Directed line segment.Specifically can input sequencing namely each tracing point based on each tracing point capture sequencing, structure Build the directed line segment in sliding trajectory.Successively using each tracing point as starting point, using the latter tracing point of current trace points as terminal Construct directed line segment.

For example, for one kind shown in Fig. 1 C for " zhongguo " on the virtual keyboard slide captured tracing point Schematic diagram.It can so construct to obtain directed line segment as shown in figure iD based on tracing point shown in Fig. 1 C.

Step 120, it is based on the directed line segment, confirms N number of final alternative key corresponding with the directed line segment；It is described N is natural number.

After building obtains sliding corresponding directed line segment, then directed line segment, confirmation and each directed line segment can be based on Corresponding N number of final alternative key, wherein N is natural number.

In practical applications, the sphere of action of each key in dummy keyboard is limited and relatively-stationary, then In the embodiment of the present invention, the corresponding key of sphere of action according to belonging to each directed line segment region, and then determine phase Answer the final alternative key of directed line segment；In addition, in embodiments of the present invention, being also based on directed line segment apart from dummy keyboard In the distance of each key and/or the distance etc. of certain point each key in dummy keyboard in directed line segment, and then confirm The final alternative key of corresponding directed line segment；Alternatively, can also respectively be had using the combination confirmation of above-mentioned one or more methods To the corresponding final alternative key of line segment；Or it can also be for deflecting directed line segment and non-deflecting directed line segment using different Method determine its final alternative key.

In embodiments of the present invention, the tool for confirming the corresponding final alternative key of each directed line segment can be set according to demand Body scheme is not limited this embodiment of the present invention.

Moreover, in embodiments of the present invention, a directed line segment can correspond to one or more final alternative keys, it can also Any final alternative key can not be corresponded to, this embodiment of the present invention is not limited.

For example, first the corresponding key of sphere of action according to belonging to each directed line segment region, confirmation should can mutually have To the corresponding initial alternative key of line segment, and then distance and/or phase based on corresponding directed line segment apart from each initial alternative key Distance of the certain point apart from each initial alternative key in directed line segment is answered, determines the final alternative key of corresponding directed line segment； Etc..

Step 130, progressive extension is carried out to the final alternative key based on default vocabulary, obtains candidate word.

Default vocabulary therein can be preset according to demand, be not limited to this embodiment of the present invention.That Then progressive extension can be carried out to the final alternative key based on default vocabulary, obtain candidate word.

It should be noted that in embodiments of the present invention, it is understood that there may be the corresponding final alternative key of certain directed line segments Quantity is one, and being also likely to be present the corresponding final alternative key of certain directed line segments certainly is empty and certain directed line segments pair Answer multiple final alternative keys.

It in embodiments of the present invention, then can be based on the input sequencing of each directed line segment, according to each directed line segment Corresponding final alternative key, lookup and the matched word of current final alternative key in default vocabulary, and then accordingly slided The corresponding candidate word of row.

For example, it is assumed that for the multiple tracing points slided currently captured, the final alternative key of acquisition is followed successively by { (a, b, c), (), (n, m), (i, g) }, and default vocabulary are as follows: a, an, ao, ang, ba, ban, bo, bin, bing.

So, progressive extension is carried out to the final alternative key based on default vocabulary, it is known that for first directed line The corresponding final alternative key (a, b, c) of section, a and b in initial character in default vocabulary as existing, and c is not present, therefore by first The first spreading result of a corresponding final candidate key acquisition of directed line segment are as follows: " a, b ", the second directed line segment are corresponding final standby It selects key for sky, can not consider, final alternative key (n, m) corresponding for third directed line segment, in previous extension As a result on the basis of, n is combined forward with a and b respectively, obtains an and bn, by searching for default vocabulary, determines that an exists, bn is not In the presence of, and m is free of in the second character of above-mentioned default vocabulary, therefore obtained by the corresponding final candidate key of third directed line segment The second spreading result are as follows: " an ", final alternative key (i, g) corresponding for the 4th directed line segment, in previous extension knot On the basis of fruit, i and g are combined forward with an respectively, are obtained ani and ang by searching for default vocabulary and are determined that ani is not present, Ang exists, therefore is " ang " by the final spreading result that the corresponding final candidate key of the last one directed line segment obtains, namely Progressive extension is carried out to above-mentioned final alternative key based on default vocabulary, obtained candidate word is " ang ".

In embodiments of the present invention, progressive extension is being carried out to the final alternative key currently confirmed based on default vocabulary Afterwards, it is likely to be obtained at least one candidate word, naturally it is also possible to corresponding candidate word can not be acquired in default vocabulary.So The case where for not getting candidate word, can then be prompted by predetermined manner, and predetermined manner therein can basis Demand is preset, and is not limited to this embodiment of the present invention.

Such as the prompting frame for returning to blank box or including prompt text can be set, or pass through voice prompting, Etc..

After the corresponding candidate word of multiple tracing points for having determined with having captured, then it can show each candidate word, have The candidate word exhibition method of body can be preset according to demand, be not limited to this embodiment of the present invention.Such as it can Candidate word, etc. is shown in the display interface in corresponding mobile terminal in the form of suspended frame.

A kind of slide input method according to the present invention can capture the multiple tracing points slided on the virtual keyboard, and Capture sequencing based on the tracing point, with the directed line segment in two tracing point building sliding trajectories of arbitrary continuation；Base In the directed line segment, N number of final alternative key corresponding with the directed line segment is confirmed；Based on default vocabulary to described final Alternative key carries out progressive extension, obtains candidate word.Thus it solves and slides input reaction speed in the prior art slowly and develop Technical problem at high cost.Achieve the beneficial effect for improving and sliding input reaction speed while reducing development cost.

Embodiment two

Referring to Fig. 2, a kind of step flow chart of slide input method in the embodiment of the present invention is shown.

Step 210, the multiple tracing points slided on the virtual keyboard are captured, and the capture based on the tracing point is successively suitable Sequence, with the directed line segment in two tracing point building sliding trajectories of arbitrary continuation.

Step 220, judge the directed line segment whether be deflecting directed line segment.

In practical applications, when user is slided on the virtual keyboard with selected virtual key, if current directed line segment Direction change relative to previous directed line segment, then directed line segment direction change when, user selectes virtual key A possibility that it is larger.

Moreover, if it changes relative to the direction of previous directed line segment, illustrating for directed line segment The starting point of current directed line segment, the line of travel of user change；And if current directed line segment is relative to previous oriented The direction of line segment does not change, then illustrates the starting point in current directed line segment, and the line of travel of user does not change.

It therefore,, can be with before final alternative key corresponding according to directed line segment confirmation for above-mentioned different situations First judge whether each directed line segment is the direction of the directed line segment namely each directed line segment of deflecting relative to its previous directed line segment Whether change.

In embodiments of the present invention, any methods availalbe can be used to judge directed line segment whether for the directed line of deflecting Section, is not limited this embodiment of the present invention.For example, can side based on current directed line segment relative to previous directed line segment To offset, confirm whether current directed line segment is directed line segment of deflecting, etc..

Optionally, referring to Fig. 2A, in embodiments of the present invention, the step 220 be can further include:

Sub-step 221 obtains the first angle between the directed line segment and previous directed line segment.

In embodiments of the present invention, can be judged based on the angle between two directed line segments latter directed line segment whether be The directed line segment of deflecting.So firstly the need of the first angle obtained between directed line segment and previous directed line segment.Two oriented The value range of angle is " 0 ° -180 ° ", therefore the value range of the first angle in embodiments of the present invention between line segment For " 0 ° -180 ° ".Such as the first angle schematic diagram that Fig. 2 B is former and later two directed line segments.ɑ 1 therein is the first angle.

Sub-step 222 confirms that the directed line segment is deflecting if first angle is greater than first angle threshold value Directed line segment.

Sub-step 223 confirms the directed line segment if first angle is less than or equal to the first angle threshold value For the directed line segment of non-deflecting.

First angle threshold value therein can be preset according to demand, not limited this embodiment of the present invention It is fixed.

For example, it is 10 ° that first angle threshold value, which can be set, if that current directed line segment and previous directed line segment First angle is greater than 10 °, then can be confirmed that current directed line segment is the directed line segment of deflecting；And if current directed line segment It is less than or equal to 10 ° with the first angle of previous directed line segment, then can be confirmed that current directed line segment is having for non-deflecting To line segment.

Step 230, if the directed line segment is the directed line segment of deflecting, the starting point based on the directed line segment is to often The first distance of a alternative key confirms the final alternative key of the directed line segment；Wherein, the alternative key has to be described Virtual key into line segment periphery preset range.

It has been observed that when user is slided on the virtual keyboard with selected virtual key, if the direction of current directed line segment Change relative to previous directed line segment, then directed line segment direction change when, select virtual key a possibility that compared with Greatly.And for the directed line segment of deflecting, the line of travel of user at this time changes, and is the directed line segment in deflecting Starting point line of travel change.

It therefore, in embodiments of the present invention, can be based on described if the directed line segment is the directed line segment of deflecting The starting point of directed line segment confirms the final alternative key of the directed line segment to the first distance of each alternative key.

Wherein, the alternative key is the virtual key in the preset range of the directed line segment periphery.Default model therein Enclose to be preset according to demand, be not limited to this embodiment of the present invention.Such as preset range can be set and be Region etc. of the distance in the first pre-determined distance apart from corresponding directed line segment starting point, then different directed line segment institutes are right at this time The alternative key answered can be not exactly the same, naturally it is also possible to there is a situation where it is identical, and therein first it is default away from From that can be preset according to demand, this embodiment of the present invention is not limited.Also alternative key, which can be set, is Whole virtual keys that dummy keyboard is included, 9 virtual keys or full keyboard in nine grids keyboard as escribed above In 26 virtual keys.Certainly, in embodiments of the present invention, the particular content of alternative key can also be set according to demand, This embodiment of the present invention is also not limited.

Optionally, referring to Fig. 2A, in embodiments of the present invention, the step 230 be can further include:

Sub-step 231 obtains the starting point of the directed line segment to the first distance of each alternative key.

In embodiments of the present invention, can the starting point based on the directed line segment of deflecting to its corresponding each alternative key First distance confirms the final alternative key of corresponding directed line segment.The starting point for so then needing to obtain the directed line segment of deflecting arrives The first distance of corresponding each alternative key.Specifically first distance can be obtained using any methods availalbe, to this this hair Bright embodiment is not limited.

Corresponding alternative key is determined as described by sub-step 232 when the first distance is less than first distance threshold value The final alternative key of directed line segment.

After acquiring first distance, then it can further judge whether first distance is less than first distance threshold value, And if the starting point of the directed line segment of deflecting to its corresponding a certain alternative key first distance less than the first pre-determined distance, It can be confirmed that the alternative key is a final alternative key of the directed line segment.

First distance threshold value therein can be preset according to demand, furthermore, it is possible to be arranged for different deflectings The first distance threshold value of directed line segment is identical, and the first distance threshold value that also can be set for different deflecting directed line segments is endless It is exactly the same, this embodiment of the present invention is not limited.

It is as shown in Figure 2 C a kind of final alternative key schematic diagram of directed line segment for confirming deflecting.Wherein " G " key arrives The first distance of corresponding deflecting directed line segment is less than first distance threshold value shown in dashed box in figure, therefore, for the deflecting The final alternative key of directed line segment is " G " key.

Step 240, if the directed line segment is the directed line segment of non-deflecting, had described in based on each alternative key To the second distance of line segment, the final alternative key of the directed line segment is confirmed.

And if the direction of current directed line segment has not been changed relative to previous directed line segment, namely if current directed line segment For the directed line segment of non-deflecting, then the starting point of current directed line segment is not necessarily based on to the distance of each alternative key, is worked as with confirmation The final alternative key of preceding directed line segment, but can be directly based upon each alternative key to current directed line segment second away from From confirming the final alternative key of corresponding directed line segment.

Alternative key at this time is alternative key corresponding to the directed line segment of corresponding non-deflecting.Certainly alternative key can be with For whole virtual key included in dummy keyboard, or preset model on the directed line segment periphery second of corresponding non-deflecting Virtual key etc. in enclosing.Second preset range therein can be preset according to demand, be implemented to this present invention Example is not limited.Certainly, in embodiments of the present invention, can also be arranged according to demand corresponding to the directed line segment of non-deflecting The particular content of alternative key, is also not limited this embodiment of the present invention.

Optionally, referring to Fig. 2A, in embodiments of the present invention, the step 240 be can further include:

Sub-step 241 obtains each alternatively second distance of the key to the directed line segment.

In embodiments of the present invention, can the directed line segment based on non-deflecting to the second of its corresponding each alternative key Distance confirms the final alternative key of corresponding directed line segment.The directed line segment for so then needing to obtain non-deflecting is corresponding each Second distance of the alternative key to corresponding directed line segment.Specifically second distance can be obtained using any methods availalbe, to this The embodiment of the present invention is not limited.

Corresponding alternative key is determined as described by sub-step 242 if the second distance is less than second distance threshold value The initial alternative key of directed line segment.

After acquiring second distance, then it can further judge whether second distance is less than second distance threshold value, And if a certain alternative key to its corresponding non-deflecting directed line segment second distance less than the second pre-determined distance, can be true Recognize the initial alternative key that the alternative key is the directed line segment.

Second distance threshold value therein can be preset according to demand, furthermore, it is possible to be arranged for different non-changes Second distance threshold value to directed line segment is identical, and the second distance threshold value for different non-deflecting directed line segments can be set It is not exactly the same, this embodiment of the present invention is not limited.

Such as the initial alternative key schematic diagram that Fig. 2 D is a kind of directed line segment for confirming non-deflecting." F " key therein with And the second distance of " G " key to the accordingly directed line segment of non-deflecting is less than second distance threshold value, therefore, for the non-deflecting The initial alternative key of directed line segment is " F " key and " G " key.

Whether sub-step 243 judges the directed line segment far from the initial alternative key.

In practical applications, if current directed line segment does not change relative to the direction of previous directed line segment, Its possible same virtual key corresponding with previous directed line segment, and if continuous two directed line segments and same void The distance of quasi- key is all in first distance threshold range, then can then assert user's continuous trigger at this time, this is same virtual twice Key.But only need to may to trigger the virtual key primary for the original idea of user, in addition once only wishes to leave the virtual key Slide action, and be mistaken for triggering virtual key.

It therefore, in embodiments of the present invention, can be for the oriented of non-deflecting in order to avoid such as above-mentioned erroneous judgement situation The initial alternative key of line segment carries out postsearch screening, to obtain the final alternative key of the directed line segment of corresponding non-deflecting.

It specifically can further judge the directed line segment of each non-deflecting whether far from its corresponding initial alternative key. Wherein, if its corresponding a certain initial alternative key is directed toward in the direction of the directed line segment of non-deflecting, it can be assumed that this is oriented Line segment is no far from the initial alternative key, and if the direction of the directed line segment of non-deflecting is corresponding a certain initial standby away from its Key is selected, then it can be assumed that the directed line segment is far from the initial alternative key.In embodiments of the present invention, can using it is any can Whether the directed line segment for judging non-deflecting with method is not subject to this embodiment of the present invention far from its corresponding initial alternative key It limits.

Optionally, in embodiments of the present invention referring to Fig. 2 E, the sub-step 243 can further include:

Sub-step 2431 is first whole with the initial alternative key with the starting point of the directed line segment for the first starting point Point, building obtain the first directed line segment.

In embodiments of the present invention, in order to improve non-deflecting directed line segment final alternative key accuracy, can be with base Postsearch screening is carried out to initial alternative key in angle.It specifically can be first using the starting point of the directed line segment of non-deflecting as the first Point, using the corresponding initial alternative key of the directed line segment of the non-deflecting as First terminal point, building obtains the first directed line segment.

Such as shown in Fig. 2 F, it is assumed that alternative key initial for one of non-deflecting directed line segment shown in Fig. 2 F is " F " key, then at this time then can the starting point of the directed line segment be the first starting point, using the initial alternative key as First terminal point, Building obtains the first directed line segment as shown in the phantom line segments in Fig. 2 F.

Sub-step 2432 obtains the second angle of first directed line segment and the directed line segment.

It has been observed that the value range of angle is " 0 ° -180 ° " between two directed line segments, therefore in embodiments of the present invention The value range of the second angle be also " 0 ° -180 ° ".First directed line segment and corresponding directed line segment as shown in Figure 2 F Second angle schematic diagram, ɑ 2 therein are the first angle.

In embodiments of the present invention, can be obtained by any methods availalbe first directed line segment with it is corresponding oriented Second angle of line segment, is not limited this embodiment of the present invention.

Sub-step 2433 confirms the directed line segment far from institute if second angle is greater than second angle threshold value State initial alternative key.

After acquiring the second angle, then it can further judge whether the second angle is greater than second angle threshold value, And if the second angle of a certain initial alternative corresponding first directed line segment of key and the directed line segment of corresponding non-deflecting is greater than Second angle threshold value then can be confirmed the directed line segment of corresponding non-deflecting far from the initial alternative key；And if a certain initial Second angle of alternative corresponding first directed line segment of key and the directed line segment of corresponding non-deflecting is less than or equal to second angle threshold Value then can be confirmed the directed line segment of corresponding non-deflecting close to the initial alternative key.Second angle threshold value therein can root It is preset according to demand, this embodiment of the present invention is not limited.

If it is 90 ° that second angle threshold value, which is arranged, as shown in Figure 2 F, if ɑ 2 is less than or equal to 90 °, confirmation has To line segment close to corresponding initial alternative key " F ", if ɑ 2 is greater than 90 °, confirm directed line segment far from corresponding initial standby Select key " F ".

Sub-step 244, if the directed line segment deletes the initial alternative key far from the initial alternative key It removes.

And if the directed line segment of a certain non-deflecting is identified as illustrating far from its corresponding a certain initial alternative key User's sliding at this time is and to select other virtual key in order to far from the initial alternative key, then at this time then can will The initial alternative key is deleted；And if the directed line segment of a certain non-deflecting be identified as it is corresponding a certain initial alternative close to its Key then illustrates that user's sliding at this time is in order to select the initial alternative key, then at this time then can be initial alternative by this Key retains.

Sub-step 245, using the initial alternative key of reservation as the final alternative key of the directed line segment.

It, then can be corresponding initial alternative by what is retained after secondary filter for the directed line segment of each non-deflecting Key is as its final alternative key.

It is further to note that in embodiments of the present invention, it can not also be to the initial standby of the directed line segment of non-deflecting Select key carry out secondary filter, and by its all as accordingly non-deflecting directed line segment final alternative key, to this this hair Bright embodiment is not limited.

Step 250, as unit of single character, the default vocabulary is converted into tree structure figure.

In embodiments of the present invention, progressive extension is carried out to each final alternative key according to default vocabulary for convenience, it can As unit of single character, corresponding default vocabulary is converted into tree structure figure.

For example, it is assumed that default vocabulary are as follows: a, an, ao, ang, ba, ban, bo, bin, bing, then being single with single character The default vocabulary is converted to available tree structure figure as shown in Figure 2 G after tree structure figure by position.

Moreover, because the alphabet in default vocabulary is contained in tree structure figure, then obtaining tree-like knot in building After composition, the vocabulary that may be constructed with the corresponding character of node layer each in tree structure figure may be beyond the model of default vocabulary It encloses.For example, b, i, bi, etc. vocabulary counter can be released for the tree structure figure of above-mentioned default vocabulary building.But b, i, bi Not inside above-mentioned default vocabulary, and then the tree structure figure after building is caused to expand the content of default vocabulary.

Therefore, in embodiments of the present invention, in order to avoid above situation, in the tree-like knot being converted to based on default vocabulary In composition, notation methods can be preset, the node in tree structure figure is labeled, be properly termed as with characterizing corresponding node Leaf node namely the corresponding character of the node can be used as the last character in vocabulary.Default notation methods therein It can be preset according to demand, this embodiment of the present invention is not limited.For example, can be as shown in Figure 2 G, with circle Collimation mark infuses leaf node, then will not then obtain the vocabulary to end up with " b " and " i " based on the tree structure figure at this time, namely not " b ", " i " and " bi " can be released.

Step 260, according to the corresponding final alternative key of each node layer in the tree structure figure, according to the directed line The input sequencing of section carries out progressive extension to the final alternative key of the directed line segment, obtains candidate word.

After building obtains tree structure figure, can be confirmed in tree structure figure each layer node it is corresponding it is final alternatively by Key, and then can be according to the corresponding final alternative key of each node layer in the tree structure figure, according to the directed line segment Sequencing is inputted, progressive extension is carried out to the final alternative key of the directed line segment, obtains candidate word.

For example, it is assumed that for the multiple tracing points slided currently captured, the final alternative key of acquisition is followed successively by { (a, b, c), (), (n, m), (i, g) }, and default vocabulary are as follows: a, an, ao, ang, ba, ban, bo, bin, bing, for this Default vocabulary is converted to available tree structure figure as shown in Figure 2 G.Moreover, because what is currently captured slides multipair answer The second directed line segment final alternative key be sky, can be ignored, then the first layer in tree structure figure can be confirmed Node corresponds to final alternative key (a, b, c), the second layer node in tree structure figure correspond to final alternative key (n, M), the third layer node in tree structure figure corresponds to final alternative key (i, g).

So, according to the corresponding final alternative key of each node layer in the tree structure figure, according to the directed line segment Input sequencing, progressive extension is carried out to the final alternative key of the directed line segment, it is known that for first directed line The corresponding final alternative key (a, b, c) of section, a and b exist in the first-level nodes of tree structure figure, and c is not present, therefore by The corresponding final candidate key of first directed line segment obtains the first spreading result are as follows: " a, b "；For third directed line segment pair The final alternative key (n, m) answered, on the basis of previous spreading result, n is combined forward with a and b respectively, obtains an and bn, By searching for tree structure figure, determine that an exists in the second layer node of tree structure figure, and bn is not present, and it is above-mentioned tree-like M is free of in the second layer node of structure chart, therefore by the second extension of the corresponding final candidate key acquisition of third directed line segment As a result are as follows: " an "；Final alternative key (i, g) corresponding for the 4th directed line segment, on the basis of previous spreading result, I and g is combined forward with an respectively, obtains ani and ang, by searching for tree structure figure, determines ani the of tree structure figure It is not present in three-layered node point, and ang exists in the third layer node of tree structure figure, therefore corresponded to by the last one directed line segment The final spreading result that obtains of final candidate key be " ang ", namely final alternatively pressed based on tree structure figure to above-mentioned Key carries out progressive extension, and obtained candidate word is " ang ".

Step 270, according to the inflection point number of the sliding trajectory and/or the candidate word relative to the sliding trajectory Key distance, confirm the weight order of the candidate word；Wherein, the key distance slides rail described for the candidate word Corresponding directed line segment in mark, at a distance from final alternative key corresponding with the candidate word and the directed line segment.

It has been observed that in practical applications, for the multiple tracing points slided on the virtual keyboard captured, can be confirmed Multiple candidate words are obtained, then when showing candidate word, the problem of there is sequencing.Therefore, in embodiments of the present invention, Can key distance according to the inflection point number and/or the candidate word of the sliding trajectory relative to the sliding trajectory, really Recognize the weight order of the candidate word.

It can be specifically based on each candidate word, confirm each candidate word corresponding directed line segment in sliding trajectory, and then obtain Take the corresponding directed line segment of each candidate word inflection point number and corresponding directed line segment to corresponding candidate word and corresponding oriented The key distance of the corresponding final alternative key of line segment, and then the weight order based on above-mentioned parameter confirmation corresponding candidate word.Tool Corresponding relationship between the inflection point number and weight order and key distance and weight order of body can carry out pre- according to demand First it is arranged, this embodiment of the present invention is not limited.

Moreover, wherein the inflection point of sliding trajectory can be understood as the tracing point for meeting default inflection point condition, it is therein default Inflection point condition can be preset according to demand, be not limited to this embodiment of the present invention.

For example, and it is an inflection point that the starting point of the directed line segment of deflecting in sliding trajectory, which can be set,；Or it can be set Inflection point needs to meet at least one of following two condition: first condition, and curvature is greater than preset curvature threshold value；Second Condition, the curvature in several tracing points (i.e. a certain section of sliding trajectory) that are connected are maximum；Etc..

For example, for above-mentioned candidate word " ang ", it is assumed that " a " therein is oriented corresponding to first in sliding trajectory Line segment, " n " correspond to second directed line segment in sliding trajectory, and " g " corresponds to the 4th directed line segment in sliding trajectory. So for the key distance for obtaining corresponding sliding trajectory, then first directed line segment can be obtained respectively to final alternative key The distance of " a ", the distance of second directed line segment to final alternative key " n ", the 4th directed line segment to final alternative key The distance of " g ".Three distances that at this time then can be directly above-mentioned can also further calculate three distances as key distance It is used as key distance with value, this embodiment of the present invention is not limited.

It, then can be just for if the partial character in candidate word is consistent in addition, in embodiments of the present invention Inconsistent part in candidate word is slided according to the inflection point number of the sliding trajectory and/or the candidate word relative to described The key distance of track, confirms the weight order of the candidate word.

Step 280, the candidate word is shown according to the sequence of the weight order from high to low.

For example, it is assumed that the candidate word finally obtained has hello, help, then judge last in the sliding trajectory captured One directed line segment is that " O " key in dummy keyboard is closer, or closer from " P " key, if the last one directed line " P " key ratio " O " key of section in dummy keyboard is closer, then can be confirmed that the weight order of " help " is higher than " hello " Weight order, then first word recommended to the user is " help " at this time, second word is " hello ".

A kind of slide input method according to the present invention can capture the multiple tracing points slided on the virtual keyboard, and Capture sequencing based on the tracing point, with the directed line segment in two tracing point building sliding trajectories of arbitrary continuation；Base In the directed line segment, N number of final alternative key corresponding with the directed line segment is confirmed；Based on default vocabulary to described final Alternative key carries out progressive extension, obtains candidate word.To improve the reaction speed for sliding input and meanwhile reduce develop at This.

Moreover, in embodiments of the present invention, can also judge the directed line segment whether be deflecting directed line segment；If The directed line segment is the directed line segment of deflecting, then starting point based on the directed line segment to each alternatively key first away from From confirming the final alternative key of the directed line segment；If the directed line segment is the directed line segment of non-deflecting, based on every A alternative key confirms the final alternative key of the directed line segment to the second distance of the directed line segment.Also, it can be with Obtain the first angle between the directed line segment and previous directed line segment；If first angle is greater than first angle threshold Value then confirms that the directed line segment is the directed line segment of deflecting；If first angle is less than or equal to the first angle threshold Value then confirms that the directed line segment is the directed line segment of non-deflecting.And the starting point of the directed line segment is obtained to each alternative The first distance of key；When the first distance is less than first distance threshold value, by corresponding alternative key be determined as described in have To the final alternative key of line segment.So as to further increase the accuracy of final alternative key, to further increase cunning The reaction speed of row input.
