Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, fig. 1 is a diagram illustrating a handwriting input interface of a handwriting input method according to an embodiment of the present invention, and fig. 2 is a diagram illustrating a handwriting input interface of a handwriting input method according to an embodiment of the present invention.

As shown in fig. 1 and fig. 2, the handwriting input method provided by the embodiment of the invention is applied to a mobile terminal, and a handwriting input interface of the mobile terminal includes a first handwriting input area 10, a normal handwriting input area 20, and a candidate character preview area 30. The first handwriting input area 10 indicates that when an input track with a preset stroke number is input in the first handwriting input area, a corresponding candidate character queue is output; the normal handwriting input area 20 indicates that a stroke track completely corresponding to the target character needs to be input in the normal handwriting input area, and the target character is output; the candidate character preview area 30 is used to display candidate characters.

The first handwriting input represents that a candidate character queue corresponding to an input track appears in the candidate character preview area 30 as long as a user only needs to input the input track corresponding to the preset stroke number of the target character in the first handwriting input area 10, wherein the stroke number of the input track in the first handwriting input mode can be one stroke, can be two strokes, or can be multiple strokes, and the stroke number input by the user can be set according to the user requirement.

Specifically, as shown in fig. 1, the first handwriting input area 10 and the normal handwriting input area 20 may be disposed in the handwriting input interface in a split-screen manner, and in the split-screen display mode, the user may adjust the size of the first handwriting input area by himself or herself, so as to meet the diversified needs of the user.

Specifically, as shown in fig. 2, one of the first handwriting input area 10 and the normal handwriting input area 20 may also be disposed in the handwriting input interface in the form of a floating window, and in the floating window display mode, the user may control the size of the floating window input area by stretching the size of the floating window, so as to meet the diversified requirements of the user.

In the following embodiments of the present invention, the first handwriting input area is defined as a first handwriting input area, and the normal handwriting input area is defined as a second handwriting input area.

Referring to fig. 3, fig. 3 is a flowchart of a handwriting input method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

step 301, detecting a first stroke track in the first handwriting input area.

In the step, the conventional input mode at present comprises a keyboard input mode and a handwriting input mode, when the input mode is the handwriting input mode, the first stroke track in the first handwriting input area is detected, namely the first stroke track in the first handwriting input area is detected, and compared with the method that the input stroke track is detected in the normal handwriting input area, all strokes of a target character do not need to be input, the handwriting input process of a user can be simplified, and the handwriting input efficiency of the user is improved.

Step 302, a candidate character queue corresponding to the first stroke track is obtained from a first preset lexicon.

In the step, the first stroke track can be identified through the existing character identification software, and a candidate character queue corresponding to the first stroke track is obtained from a first preset word bank. In this embodiment, the first preset lexicon is an initial input lexicon.

For example, the number of the first input stroke may be preset as one stroke, and when one stroke is written in the first handwriting input area, the corresponding candidate character queue may be obtained; if the second stroke is written in the first handwriting input area, the second stroke is the first stroke of the second candidate character. Accordingly, if the preset first stroke is two, a candidate character is output every time two strokes are written in the first handwriting input area.

Step 303, determining a target character from the candidate character queue, and outputting the target character.

In this step, a target character may be determined from the candidate character queue by receiving a preset operation of the user, such as a click operation, and the target character is output to output the content of the handwriting input of the user.

It should be noted that, in the embodiment of the present invention, it may be determined whether the current input belongs to the first handwriting input or the normal handwriting input by determining the initial input position of the first input trajectory. For example, when an input stroke is long and the input stroke is drawn from the first handwriting input area to the normal handwriting input area, the input stroke belongs to the first handwriting input because the starting position of the input stroke is located in the first handwriting input area. Similarly, if another input stroke is long and the initial position of the input stroke is located in the normal handwriting input area, the input stroke belongs to the normal handwriting input if the input stroke is drawn from the normal handwriting input area to the first handwriting input area.

In the embodiment of the present invention, the mobile terminal may be any mobile terminal having a human body feature acquisition component and a screen, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.

The handwriting input method comprises the steps of detecting a first stroke track in a first handwriting input area; acquiring a candidate character queue corresponding to the first stroke track from a first preset word bank; and determining a target character from the candidate character queue and outputting the target character. Therefore, the corresponding target character can be obtained by detecting the input stroke track in the first handwriting input area, and compared with the method of inputting all strokes of the target character, the method can simplify the handwriting input process and improve the handwriting input efficiency.

Referring to fig. 4, fig. 4 is a flowchart of a handwriting input method according to another embodiment of the present invention, as shown in fig. 4, including the following steps:

step 401, detecting a first stroke track in the first handwriting input area.

Step 402, obtaining the stroke number of the first stroke track.

In this step, the stroke number of the first stroke track may be obtained in a basic stroke recognition manner.

For example, the number of strokes of the at least one basic stroke may be determined by identifying the basic strokes included in the first stroke track, calculating the sum of the number of strokes of the at least one basic stroke in the first stroke track, and determining the sum of the number of strokes of the at least one basic stroke as the number of strokes of the first stroke track.

In particular, the basic strokes of, for example, Chinese characters include points (left), horizontal (I), vertical (I), left falling (I), I

8 types of strokes such as bent (five strokes), hooks (stroke) can be through discerning which several kinds of basic strokes first stroke orbit includes to according to the quantity of basic strokes in the first stroke orbit, obtain the stroke number of first stroke orbit.

And 403, judging whether the stroke number is less than a preset stroke number.

In this step, the character input may be determined according to a size relationship between the number of strokes and the number of strokes set in advance. When the number of strokes of the first stroke track is less than the preset number of strokes, executing step 404; and when the stroke number of the first stroke track is larger than the preset stroke number, ending the process. When the number of strokes of the first stroke track exceeds the preset number of strokes, the redundant strokes are regarded as the input track of the next target character.

Step 404, obtaining a first character corresponding to the first stroke track from the first preset lexicon.

In this step, if the number of strokes of the first stroke track is less than the preset number of strokes, the first character corresponding to the first stroke track may be obtained from the first preset lexicon according to a preset operation, such as a click operation.

For example, the target candidate character is a Chinese character "one", the number of the input strokes of the first stroke is two, after the user inputs the "one" by handwriting, the user can finish the input of the target candidate character as the Chinese character "one" by double-clicking the handwriting input interface screen, and then the next stroke is written, so that the next target candidate word can be recognized.

Step 405, determining the first character as a target character, and outputting the target character.

In this step, the first character may be output as a target character to output the content of the user's handwriting input.

It should be noted that, in this embodiment, the number of strokes input by the user in one input process may be determined by recognizing the number of basic strokes. For example, when the first stroke track is horizontal, vertical and horizontal

By recognizing that the basic stroke of the first stroke track has two horizontal strokes (one) and one vertical stroke (one), the number of strokes input in the stroke input process is three.

The handwriting input method of the embodiment of the invention detects a first stroke track in the first handwriting input area; acquiring the stroke number of the first stroke track; judging whether the stroke number is smaller than a preset stroke number or not; if the stroke number is smaller than the preset stroke number, acquiring a first character corresponding to the first stroke track from the first preset lexicon; and determining the first character as a target character, and outputting the target character. Therefore, the corresponding target character can be obtained by detecting the input stroke track in the first handwriting input area, and compared with the method of inputting all strokes of the target character, the method can simplify the handwriting input process and improve the handwriting input efficiency.

Referring to fig. 5, fig. 5 is a flowchart of a handwriting input method according to another embodiment of the present invention, as shown in fig. 5, including the following steps:

step 501, detecting a first stroke track in the first handwriting input area.

Step 502, obtaining a candidate character queue corresponding to the first stroke track from a first preset word bank.

Step 503, detecting a second stroke track in the second handwriting input area.

In the step, a second stroke track in a second handwriting input area is detected, namely the second stroke track in a normal handwriting input area is detected, wherein the second stroke track completely corresponds to the handwriting of the character to be input.

And step 504, acquiring a second character corresponding to the second stroke track from a second preset lexicon.

In this step, the second stroke track may be recognized by existing character recognition software, and a second character corresponding to the second stroke track may be obtained from a second preset lexicon. In this embodiment, the second preset lexicon is a normal handwritten lexicon, and the normal handwritten lexicon is used for acquiring and querying a target character input by a full stroke.

It should be noted that, for example, in the process of inputting a chinese character, since the number of basic strokes of the chinese character is small, and candidate words are screened by the first stroke alone, the number of candidate words meeting the conditions obtained is large, so that when the chinese character is input by handwriting by the first stroke, the query can be assisted by normal handwriting input. In the process of first stroke input, a user can freely select the simplest Chinese character in the target candidate sentence to carry out normal input assistance.

Step 505, adding the second character to the candidate character queue.

In this step, a second character may be added to the candidate character queue. Therefore, the number of candidate character queues can be reduced, and a user can conveniently determine the target character from the candidate character queues.

For example, the character string that the user wants to input is "the best of our everyday play", the user can write two strokes of "vertical and horizontal" in the first handwriting input area, i.e. the first handwriting input area, at this time, the candidate character area will display many candidate words, the word quantity of the candidate words is relatively large, the word quantity of the candidate words in the first order is not necessarily the word that the user wants, at this time, the user feels that the word "day" is relatively well written, and the normal handwriting input area, i.e. the second handwriting input area, is selected, the output word "day" is added to the candidate word queue, and then the screening is performed, so that the number of the candidate words can be greatly abbreviated. And after the second handwriting input area inputs 'day', the user can continuously select the input operation in the first handwriting input area.

Step 506, determining a target character from the candidate character queue added with the second character, and outputting the target character.

In this step, a target character may be determined from the candidate character queue to which the second character is added by receiving a preset operation, such as a click operation, and the target character may be output. Therefore, by determining the target character from the candidate character queue added with the second character, the checking queue of the user can be greatly reduced, and the input efficiency of the user is improved.

Optionally, after the step of obtaining the candidate character queue corresponding to the first stroke trajectory from the first preset lexicon, and before the step of determining the target character from the candidate character queue and outputting the target character, the method further includes:

judging whether the target character exists in the candidate character queue or not;

if the target character does not exist in the candidate character queue, switching to a preset input mode;

the step of determining a target character from the candidate character queue and outputting the target character comprises the following steps:

and detecting the stroke track of the target character in the preset input mode, and determining and outputting the target character from a third preset word stock according to the stroke track of the target character.

In this embodiment, when there is no word matching the target character in the candidate character queue, the input mode may be set in advance by receiving a preset operation, for example, the input mode may be set in advance by pressing a normal handwriting input area for a long time, where the preset input mode is a full-stroke handwriting input mode; and then, under a preset input mode, determining and inputting the target character from a third preset word bank according to all stroke tracks of the target character by detecting all stroke tracks of the target character, wherein the third preset word bank can be a full word bank or a network word bank, and a mapping relation exists between the third preset word bank and the preset input mode. Therefore, the word library of the handwriting input mode can be effectively enriched by adding the preset input mode aiming at some rarely-used words and sentences, and the handwriting input efficiency of the user is improved.

For example, a user inputs a first stroke of ten characters in a first handwriting input area, but does not obtain a candidate word completely matched with the first stroke, at this time, the user can enter a full-stroke handwriting input mode by pressing a normal handwriting input area for a long time, and after entering the full-stroke handwriting input mode, the user screens out candidate sentences of the characters in the candidate word only by inputting all strokes of one or more characters, and reduces the number of the candidate words for the user to select. The user may exit the full stroke input mode by pressing the back key.

Moreover, the candidate word result obtained by matching with the normal handwriting input mode can be added into the first input word bank, so that the subsequent input is facilitated. If the candidate word result obtained by matching with the normal handwriting input mode exists in the first input word bank, the importance of the word is improved, and the position of the word in the candidate word queue is advanced.

Therefore, with the enrichment of the first-stroke input word bank, the importance degree of the candidate words is more and more obvious to distinguish, the speed of the user through the first-stroke handwriting input is faster and faster, the user can gradually give up using the normal handwriting input, the desired input result can be obtained through the first-stroke handwriting input directly, and the handwriting input efficiency is improved.

The handwriting input method of the embodiment of the invention detects a first stroke track in the first handwriting input area; acquiring a candidate character queue corresponding to the first stroke track from a first preset word bank; detecting a second stroke track within the second handwriting input region; acquiring a second character corresponding to the second stroke track from a second preset word stock; adding the second character to the candidate character queue; determining a target character from the candidate character queue added with the second character, and outputting the target character. Therefore, the corresponding target character can be obtained by detecting the input stroke track in the first handwriting input area, and compared with the method of inputting all strokes of the target character, the method can simplify the handwriting input process and improve the handwriting input efficiency.

Alternatively, processor 1250 may include one or more processing units.

In the embodiment of the present invention, by calling the software programs and/or modules stored in the first memory 1221 and/or the data stored in the second memory 1222, the following steps can be realized when the computer program is executed by the processor 1250: detecting a first stroke track within the first handwriting input area; acquiring a candidate character queue corresponding to the first stroke track from a first preset word bank; and determining a target character from the candidate character queue and outputting the target character.

Optionally, the computer program when executed by the processor 1250 may further implement the steps of:

acquiring the stroke number of the first stroke track;

identifying a base stroke comprised by the first stroke track;

detecting a second stroke track within the second handwriting input region;

adding the second character to the candidate character queue;

The mobile terminal 1200 can implement the processes implemented by the mobile terminal in the foregoing embodiments, and details are not repeated here to avoid repetition.

The mobile terminal 1200 of the embodiment of the present invention detects a first stroke trajectory in the first handwriting input area; acquiring a candidate character queue corresponding to the first stroke track from a first preset word bank; and determining a target character from the candidate character queue and outputting the target character.
