Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

At present, when the word is to be searched by using a dictionary pen, the word to be searched must be written down on paper, and then the word is scanned and input, so that the word searching work can be completed. Therefore, the dictionary pen has a limited use path, and cannot provide an input path for other query words.

In view of the problem, the invention provides an input method to realize a convenient and easy-to-operate input method suitable for a handheld reader, so that the input method of the handheld reader is more various. The handheld reader may be a pen-type smart device such as a scanner pen or a dictionary pen, and will be described below by taking the dictionary pen as an example. Fig. 1 is a schematic flow chart of an input method provided by the present invention, as shown in fig. 1, the method includes:

Step 110, displaying an input interface, wherein the input interface comprises a scrollable pronunciation list and an indication column for covering at least one pronunciation character in the pronunciation list;

specifically, taking word query by using a dictionary pen as an example, fig. 2 is a schematic diagram of an input interface of the input method applied to the dictionary pen provided by the present invention, as shown in fig. 2: the input interface for the words may first be presented through the display screen of the dictionary pen, wherein the input interface may comprise two columns of scrollable pronunciation lists, namely a list of selected initials and a list of selected finals. In addition, the input interface also comprises an indication column of pronunciation characters covered in the pronunciation list, namely an indication column formed by two horizontal lines at the positions of 'selecting initial consonants' and 'selecting final' in fig. 2. It can be understood that the user can select the initial list and select the final list by sliding, so that the initial and final of the word to be queried are displayed in the indication bar, that is, the initial and final of the word to be queried are selected to input the word to be queried.

Here, the pronunciation list may include an initial pronunciation list and a final pronunciation list, where the initial pronunciation list includes all initial consonants and the final pronunciation list includes all final. It should be noted that, compared with the input by the initial consonant displayed in the form of the nine-square or twenty-six-square keyboard in the prior art, the keyboard for input is larger, but the display screen for displaying the keyboard is smaller, so that the user easily makes a false touch on the display screen. The pronunciation list in the embodiment of the invention can be scrolled, so that more initial consonants and more consonants can be clearly and orderly displayed on a smaller display screen of a handheld reader such as a dictionary pen, and the user can more conveniently select the pronunciation list. In addition, the display order of the pronunciation characters in the pronunciation list may be in a custom order, or in a specific order, for example, the display order of the most commonly used pronunciation characters is forward, for example, when one of the pronunciation characters is selected, the display order of the pronunciation characters in the other list, which can be combined with the selected pronunciation character, is forward.

In addition, the indicator fields herein may be presented in the form of boxes, cross lines, arrows, etc., and the phonetic characters in the indicator fields may be presented in the form of highlighting. For a single pronunciation list, the indication column may cover a single pronunciation character or may cover a space. Thus, for all the pronunciation lists, the indication column covers at least one pronunciation character in the pronunciation list. It can be understood that the pronunciation characters covered in the indication column can be pinyin combinations of the characters to be queried corresponding to the user.

Step 120, receiving a scrolling operation for the pronunciation list, responding to the scrolling operation, scrolling the pronunciation list, and determining target pronunciation characters covered in the indication column based on the pronunciation list after scrolling;

specifically, taking a dictionary pen for manually inputting query characters as an example, the dictionary pen receives a scrolling operation of a user on a pronunciation list, and scrolls the pronunciation list in response to the scrolling operation, and after the scrolling is completed, the pronunciation characters covered by the indication column in the pronunciation list are target pronunciation characters. The scrolling operation may be that the user scrolls the pronunciation list upwards or downwards, and the receiving scrolling operation may be that the user swipes the input interface, for example, the user swipes the input interface upwards, and the scrolling operation for the pronunciation list is scrolling upwards; and when receiving the downward swipe operation of the user on the input interface, the scrolling operation aiming at the pronunciation list is downward scrolling. Alternatively, by receiving a press of a similar volume key, for example, receiving a press of a plus volume key by the user, the scroll operation for the pronunciation list is scroll up; when the user presses the minus volume key, the scrolling operation for the pronunciation list is scrolling down.

It should be noted that, the scrolling operation performed by the user with respect to the pronunciation list is performed with respect to a single pronunciation list, that is, when the pronunciation list is plural, the user may scroll with respect to the single pronunciation list one by one. Thus, the received and responsive scrolling operation on the list of readings is also for a single list of readings. In detail, when scrolling its reading list in response to a scroll operation for the reading list thereof, another reading list is not scrolled at the same time, and the scroll operation for the same reading list may be repeatedly received.

In addition, the target pronunciation characters are pronunciation characters in each pronunciation list covered by the indication column, and pronunciation of the character to be queried can be obtained by spelling and combining the target pronunciation characters, so that the character to be queried is determined.

Step 130, displaying the candidate characters under the target pronunciation characters;

specifically, the candidate characters under the target pronunciation can be displayed by displaying the target pronunciation and the candidate characters under the target pronunciation, for example, the candidate characters under the target pronunciation characters with different tones can be displayed by displaying the target pronunciation characters with different tones. Fig. 3 is one of schematic diagrams showing candidate characters under a target pronunciation character, as shown in fig. 3, the target pronunciation character may be marked with each tone to display the target pronunciation character marked with the tone, and the candidate characters corresponding to the target pronunciation character marked with the tone are displayed under the target pronunciation character marked with the tone. In consideration of the fact that the display screen of the handheld reader such as a dictionary pen is small, the target pronunciation characters marked with the tone can be linked with the corresponding candidate characters, and after the input operation of the target pronunciation of the tone is received, the candidate characters under the selected target pronunciation characters marked with the tone are displayed. When the candidate characters under other target pronunciation characters marked with the tone are required to be displayed, the input operation of the corresponding target pronunciation characters marked with the tone is only required to be received.

Or, the candidate characters under the target pronunciation characters are directly displayed, and the candidate characters in the candidate character list can be displayed in a display form similar to the pronunciation characters in the pronunciation list. Fig. 4 is a second schematic diagram of displaying candidate characters under a target pronunciation character, as shown in fig. 4, where all candidate characters under the target pronunciation character "xing" are displayed in a candidate character list, and the candidate character list may be scrolled and includes an indication field overlaid on any candidate character in the candidate character list to determine a corresponding character to be selected by a user, for example, the corresponding character to be selected by the user in fig. 4 is "Xing".

And 140, receiving an input operation aiming at the candidate characters, and determining target characters to be input from the candidate characters based on the input operation.

Specifically, as shown in the schematic illustration of the candidate text shown in fig. 3, the input operation of the candidate text received by the handheld reader may be a click operation of the user on any candidate text, and then the handheld reader may receive the click operation of the user on the candidate text, and use the candidate text corresponding to the click operation as the target text to be input. Or, as shown in the schematic illustration of the candidate text shown in fig. 4, the input operation of the candidate text received by the handheld reader may be that the user performs a sliding operation on the candidate text list, and then the handheld reader may receive the sliding operation of the user on the candidate text list, and use the candidate text in the indication column as the target text to be input.

The method provided by the embodiment of the invention comprises the steps of displaying an input interface comprising a scrollable pronunciation list and an indication column covering at least one pronunciation character in the pronunciation list; receiving a scrolling operation for the pronunciation list, scrolling the pronunciation list in response to the scrolling operation, and determining target pronunciation characters covered in the indication column based on the pronunciation list after scrolling; displaying the candidate characters under the target pronunciation characters; the input operation aiming at the candidate characters is received, the target characters to be input are determined from the candidate characters based on the input operation, the light-weight input of the characters to be queried is completed on a smaller display screen in a mode of manually selecting pinyin, the service paths of querying words through a handheld reader are richer, and the use experience of a user is further improved.

Based on any one of the above embodiments, the pronunciation list includes two lists, where the two lists correspond to initials and finals respectively;

accordingly, step 120 includes:

Specifically, the pronunciation list includes two lists, which correspond to the initials and finals, respectively, and can be recorded as the initials list and the finals list, respectively. In the input interface, the user may perform a sliding operation with respect to any one of the read sound lists, in detail, the user may slide only the initial consonant list or the final sound list, or perform a sliding operation with respect to both the initial consonant list and the final sound list. Thus, for a handheld reader such as a dictionary pen, a scroll operation for an initial list or a final list, or for an initial list and a final list, may be received, and the corresponding list is scrolled in response to the scroll operation. And determining the pronunciation character covered by the indication column in the initial list or the final list after scrolling, or in the initial list and the final list as a target pronunciation character. It can be understood that when only the scrolling operation for the initial list or the final list is received, the pronunciation character covered in the indication column is the initial pronunciation character or the final pronunciation character, i.e. the target pronunciation character is the initial pronunciation character or the final pronunciation character; when the scrolling operation for the initial list and the final list is received, the pronunciation characters covered in the indication column are the initial pronunciation characters and the final pronunciation characters, namely, the target pronunciation characters are the initial pronunciation characters and the final pronunciation characters.

Compared with the current general input method through a nine-square grid or a twenty-six square grid, the method provided by the embodiment of the invention has the advantages that the pronunciation list is divided into the initial list and the final list, the scrolling operation for at least one list is received, the at least one list is scrolled in response to the scrolling operation, and the target pronunciation characters covered in the indication column are determined based on the at least one list after the scrolling is completed, so that the light-weight character input on a handheld reader with a limited display screen size such as a handheld reader is realized.

Based on any of the above embodiments, fig. 5 is a flowchart of a method for determining target pronunciation characters according to the present invention, as shown in fig. 5, in step 120, the receiving a scrolling operation for at least one list, scrolling the at least one list in response to the scrolling operation, and determining target pronunciation characters covered in the indicator bar based on the at least one list after scrolling is completed, including:

step 510, receiving a first scrolling operation for any list, scrolling the any list in response to the first scrolling operation, and determining a first target pronunciation character covered in the indication column based on the any list after scrolling is completed;

Step 520, adjusting the pronunciation character in another list based on the first target pronunciation character;

step 530, receiving a second scrolling operation for the other list, scrolling the other list in response to the second scrolling operation, and determining a second target pronunciation character covered in the indication bar based on the other list after scrolling is completed.

It should be noted that, here, "first" in the first scroll operation, "first" in the first target pronunciation character, and "second" in the second scroll operation, "second" in the second target pronunciation character, etc. are used to distinguish similar objects, it should be understood that terms so used may be interchanged as appropriate, so that the embodiments of the present invention can be implemented in an order other than described herein, and that the objects distinguished by "first", "second" are generally of a type, and do not limit the number of objects.

Specifically, the first target pronunciation character may be an initial pronunciation character or a final pronunciation character, and after the first target pronunciation character is determined, the pronunciation character in another list may be adjusted according to the first target pronunciation character, or the display sequence of the pronunciation characters may be adjusted, or whether each pronunciation character is displayed or not, or both the display sequence of the pronunciation characters and whether each pronunciation character is displayed or not may be adjusted. In detail, after determining the first target pronunciation character, the pronunciation character which can be spelled with the first target pronunciation character in the other list can be screened as the candidate second target pronunciation character. Further, the display order of the pronunciation characters in the other list may be refreshed, for example, the display order of the candidate second target pronunciation characters may be adjusted to be earlier, or other display orders that are convenient to select. And whether each pronunciation character in the other list is displayed or not can be adjusted, namely, the pronunciation characters displayed in the other list are adjusted, for example, the pronunciation characters except the candidate second target pronunciation characters in the other list can be deleted, and only the candidate second target pronunciation characters are displayed.

It can be understood that through the first target pronunciation character, the pronunciation character of another list is adjusted, so that the user can more conveniently and quickly input the pronunciation character of the other list, the probability of wrong pronunciation combination is reduced to a certain extent, and the use experience of the user is further improved.

Further, after the adjustment of the other list is finished, a second target pronunciation character covered in the indication column is received and determined in response to a second scrolling operation of the user on the other list.

It should be noted that, when scrolling operations for the same list are continuously received, these continuous scrolling operations are either the corresponding first scrolling operation or the second scrolling operation. For example, when the first scrolling operation of the user is received as scrolling the initial list, and then the scrolling operation of the user on the initial list is continuously received, the scrolling operation on the initial list after the first scrolling operation can be regarded as the first scrolling operation, that is, after each determination of the first target pronunciation character, the pronunciation characters of the final list are adjusted. Thus, defined herein as a first scroll operation or a second scroll operation, depending on whether the list of readings for which the scroll operation is directed changes. It is understood that the first scrolling operation may be for an initial list, or a final list; the second scrolling operation may also be for an initial list, or a final list.

According to the method provided by the embodiment of the invention, after the first target pronunciation character is determined, the pronunciation character of the other list is adjusted, and the second target pronunciation character is determined, so that convenient manual spelling input is realized, the probability of wrong pronunciation combination is reduced to a certain extent, and the use experience of a user is further improved.

Based on any of the above embodiments, step 520 includes:

Specifically, the pronunciation characters which can be combined and spelled with the first target pronunciation characters in the other list can be used as candidate pronunciation characters, so that the user can quickly and conveniently execute the operation of confirming the second target pronunciation characters after the first target pronunciation is confirmed. For example, when the first pronunciation character is "b" in the initial list, the candidate pronunciation characters may be final pronunciation characters such as "a, o, ao", etc. Further, characters other than the candidate pronunciation character in the other list may be deleted, for example, because the vowel "e" cannot be spelled in combination with "b", thereby "e" in the vowel list may be deleted from the vowel list.

Or, the display sequence of the pronunciation characters in the other list can be adjusted through the co-occurrence times when the candidate pronunciation and the first target pronunciation character are combined and spelled. In detail, the co-occurrence times of the candidate pronunciation character and the first target pronunciation character during the combined spelling can be determined through the co-occurrence times of the candidate pronunciation character and the first target pronunciation character in a character resource library stored in the handheld reader. Here, the text resource library stored by the handheld reader may be all text resources, or text resources corresponding to the level where the current user is located.

Or deleting the characters except the candidate pronunciation characters in the other list, and then adjusting the display sequence of the candidate pronunciation characters in the other list according to the co-occurrence times corresponding to each character according to the co-occurrence times when the candidate pronunciation characters and the first target pronunciation characters are combined and spelled. For example, the greater the number of co-occurrences of the candidate pronunciation character, the more forward the display order of the candidate pronunciation character; the smaller the co-occurrence number of the candidate pronunciation character is, the later the display sequence of the candidate pronunciation character is.

Here, the co-occurrence number when the candidate pronunciation character is combined spelled with the first target pronunciation character may reflect the probability that the candidate pronunciation character is the second target pronunciation character. It can be understood that, when the number of co-occurrence times is larger, the number of characters corresponding to the combined spelling of the candidate pronunciation character and the first target pronunciation character is larger, the probability that the candidate pronunciation character is used as the target pronunciation character is larger; when the co-occurrence number is smaller, the number of characters corresponding to the combined spelling of the candidate pronunciation character and the first target pronunciation character is smaller, and the probability of the candidate pronunciation character as the target pronunciation character is smaller.

It can be understood that the co-occurrence times when the candidate pronunciation characters and the first target pronunciation characters are combined and spelled are introduced, and the display sequence of the candidate characters in the other list is adjusted, so that the convenience of selecting the second target pronunciation characters by the user is further improved, and meanwhile, the use experience of the user is further improved.

The method provided by the embodiment of the invention comprises the steps of determining candidate pronunciation characters which are combined and spelled with the first target pronunciation character; and deleting the characters except the candidate pronunciation characters in the other list, and/or sequentially adjusting the pronunciation characters in the other list based on the co-occurrence times when the candidate pronunciation characters and the first target pronunciation characters are combined and spelled, so that the convenience of manually inputting the pronunciation on the handheld reader is improved, and the use experience of a user is further improved.

Based on any one of the above embodiments, fig. 6 is a schematic flow chart of determining the number of co-occurrence times, as shown in fig. 6, where the determining step of the number of co-occurrence times includes:

step 610, determining spelling of the candidate pronunciation character and the first target pronunciation character when the candidate pronunciation character and the first target pronunciation character are combined and spelled, and characters corresponding to the spelling;

specifically, spelling combinations can be performed on each candidate pronunciation and the first target pronunciation character respectively so as to determine spelling pronunciation corresponding to each candidate pronunciation character. Then, the text corresponding to the spelling reading can be determined by the spelling reading and the different tones. For example, the spelling pronunciation is "xue", and the characters corresponding to the spelling pronunciation include characters such as "learn, blood, snow, scher" and the like.

Step 620, obtaining a teaching resource library corresponding to the grade where the current user is located;

specifically, among all the text resources stored in the handheld reader, the text resources such as the history query record of the user recorded by the handheld reader, the new word list corresponding to the grade where the user is located, and the like, such as dictionary pens, can be used as a teaching resource library corresponding to the grade where the current user is located. Here, the text included in the teaching resource library is text with higher attention in the teaching stage where the user is currently located, and the possibility of the text to be queried as the user is higher than other text.

Step 630, determining the co-occurrence times when the candidate pronunciation character and the first target pronunciation character are combined and spelled based on the occurrence times of the characters corresponding to the spelling pronunciation in the teaching resource library.

Specifically, the number of characters corresponding to the spelling can be used as the occurrence number by counting the number of characters corresponding to the spelling in the teaching resource library. Then, the number of times that the text corresponding to the spelling pronunciation appears in the teaching resource library can be used as the co-occurrence number when the candidate pronunciation character and the first target pronunciation character are combined and spelled. When the user queries the word outside the level, there may be some words in the words corresponding to the spelling pronunciation, and at this time, the number of occurrences of the words corresponding to the spelling pronunciation in all the word resources may be used as the number of co-occurrences when the candidate pronunciation character and the first target pronunciation character are combined and spelled.

It will be appreciated that for a user using a handheld reader such as a dictionary pen, the user may not have a firm grasp of the pronunciation and spelling of the text, for example, after the initial is selected, a prompt needs to be given for possible final that may be selected, for example, after the initial is selected, other final that is similar to the target final character may be selected by mistake.

Aiming at the problem, the method provided by the embodiment of the invention determines the spelling pronunciation when the candidate pronunciation character and the first target pronunciation character are combined and spelled and the characters corresponding to the spelling pronunciation; next, acquiring a teaching resource library corresponding to the grade of the current user; based on the occurrence times of characters corresponding to spelling pronunciation in the teaching resource library, the co-occurrence times of the candidate pronunciation characters and the first target pronunciation characters are determined when the combination spelling is carried out, a prompt for a user to select the second target pronunciation characters is given to a certain extent, occurrence of wrong selection of other finals similar to the target finals by the user is avoided to a certain extent, and further the use experience of the user using the input method provided by the invention is greatly improved.

It will be appreciated that the text to be queried may be a single text, or a word, or even a whole sentence, when the user uses a handheld reader such as a dictionary pen. For the case that the text to be queried of the user is a plurality of text, in step 110, the displaying the input interface further includes:

determining predicted input words based on the historical input words;

Here, the history input text may be text that the user has completed inputting at the input interface, and may be used to predict text that the user is about to input next. In addition, the determination of the predicted input text herein may be performed by word-forming the history input text to determine the predicted input text. It is understood that the predicted input text is a text that is more likely to be input by the user after the input of the history input text.

Further, according to the pronunciation characters of the predicted input characters, the display sequence of the pronunciation characters in the pronunciation list is sequentially adjusted. Specifically, the pronunciation characters of the predicted input characters can be split into initials and finals, and the display sequence of each split initial and each split final in the corresponding pronunciation list is adjusted to be forward.

When the user is required to inquire the text, the order of the pronunciation characters of the pronunciation list of the input interface is adjusted after the history input of the text is completed. At this time, when a scrolling operation is received for any one of the pronunciation lists, and after the first target pronunciation character is determined, the pronunciation characters in the other list are refreshed based on the first target pronunciation character, but the display sequence of the pronunciation characters in the other list at this time may be that the display sequence of the pronunciation characters of the predicted input text corresponding to the pronunciation characters in the list is adjusted to be the most front, and then, the rest of the pronunciation characters in the list are adjusted based on the first target pronunciation character.

Before the input interface is displayed, the method provided by the embodiment of the invention further comprises the step of determining predicted input characters based on the historical input characters; based on the pronunciation characters of the predicted input characters, the pronunciation characters in the pronunciation list are sequentially adjusted, so that a convenient input method can be provided during continuous input, and the use experience of a user is improved.

Based on any of the above embodiments, step 130 includes:

Specifically, the semantic association degree between the history input text and each candidate text under the target pronunciation character can be calculated by extracting the semantic features of the history input text and the semantic features of each candidate text. Then, the candidate characters are displayed from front to back according to the order of the semantic relativity from top to bottom. It can be understood that the semantic relativity can reflect the semantic connection tightness degree of the candidate characters and the historical input characters, and further can reflect the probability that the candidate characters are selected by the user as the characters to be queried.

According to the method provided by the embodiment of the invention, the semantic association degree between the historical input characters and the candidate characters under the target pronunciation characters is determined; based on the sequence of the semantic relevance from high to low, the candidate characters are displayed, and the convenience of character input under the continuous input scene is improved.
