[0076] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0077] When a user performs handwriting input on the handwriting input interface of an input method, the user can write handwriting trajectory information on the interface. The input method can recognize the handwriting trajectory information and search for candidate characters based on the recognition results. To improve the fluency of handwriting input, one of the core concepts of this application embodiment is that the input method can recognize handwritten pinyin, so that even if the user does not know how to write a certain character, they can still enter the pinyin to find the matching Chinese character.

[0078] Reference Figure 1 The diagram illustrates a flowchart of an input method provided in an embodiment of this application. The method may specifically include the following steps:

[0079] Step 101: Obtain the user's handwriting trajectory information.

[0080] When a user selects handwriting input as the input method, the input method can provide a handwriting input interface. The user can write handwriting trajectory information on the handwriting input interface, and the input method can obtain the handwriting trajectory information entered by the user.

[0081] In this embodiment, the input method supports mixed input of handwritten Pinyin, handwritten Chinese characters, and handwritten English letters. Handwriting trajectory information can include the trajectories of handwritten Pinyin, handwritten Chinese characters, and handwritten English letters. The input method can distinguish between these trajectories. Handwritten Pinyin is identified as Pinyin; handwritten Chinese characters are identified as handwritten Chinese characters; and handwritten English letters are identified as handwritten English letters. For example, the input method's handwriting kernel can be invoked to recognize handwriting trajectory information. The handwriting kernel is a module used to recognize handwriting trajectory information and can identify different types of handwriting trajectory information through recognition models, algorithms, and other rules.

[0082] In practice, when users write Pinyin, they can also write the phonetic symbols to help the input method better distinguish between handwritten Pinyin and handwritten English letters.

[0083] Step 102: When the handwritten pinyin is recognized based on the handwritten trajectory information, a matching candidate is searched based on the handwritten pinyin.

[0084] In an embodiment of the present application, the input method can determine candidate items according to the type of the recognized handwritten trajectory information, where the candidate items can include candidate words, expressions, images, etc.

[0085] When it is recognized from the handwritten trajectory information that the handwritten trajectory information is handwritten pinyin, candidate items that match can be searched according to the handwritten pinyin. For example, the user can input "tāo tiè" on the handwritten input interface. The input method recognizes that the handwritten trajectory information is handwritten pinyin, and searches for the matching candidate item "饕餮" according to the handwritten pinyin.

[0086] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin is recognized, the handwritten pinyin can be used as a candidate item. In practice, the user may want to select the pinyin to be input onto the screen instead of the Chinese characters matched by the pinyin. Therefore, the handwritten pinyin can be used as a candidate item.

[0087] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin is recognized, similar English letters to the handwritten pinyin can be determined, and the similar English letters can be used as candidate items.

[0088] Since handwritten pinyin and handwritten English letters are similar and are prone to writing errors. It is possible that the user wants to write pinyin but it is recognized as handwritten English letters, or it is possible that the user wants to write English letters but it is recognized as handwritten pinyin. Therefore, when recognizing including handwritten pinyin, similar English letters can be used as candidate items, which can enable the user to perceive whether an input error occurs.

[0089] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin is recognized, association can be performed on the handwritten pinyin to determine matching candidate items. Exemplarily, association can be performed on the handwritten pinyin based on the current input scenario, the context information of the current input box, etc.

[0090] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin and handwritten Chinese characters are recognized, matching candidate items can be determined based on the handwritten pinyin and the handwritten Chinese characters together.

[0091] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin and handwritten English letters are recognized, matching candidate items can be determined based on the handwritten pinyin and the handwritten English letters together.

[0092] In an optional embodiment, when it is recognized from the handwritten trajectory information that the handwritten pinyin, handwritten Chinese characters and handwritten English letters are recognized, matching candidate items can be determined based on the handwritten pinyin, handwritten Chinese characters and handwritten English letters together.

[0093] Step 103, display the candidate items.

[0094] The input method can display the searched options in the candidate bar, allowing users to select the options to display on the screen.

[0095] When there are multiple candidate options, the ranking weight of each candidate option can be determined, and the candidate options can be sorted and displayed according to the ranking weight.

[0096] For example, when handwritten pinyin is used as a candidate, a higher weight can be assigned to the handwritten pinyin candidate, so that the handwritten pinyin candidate is ranked higher.

[0097] In this embodiment, the input method can acquire the user's handwriting trajectory information. When the handwriting trajectory information includes handwritten pinyin, the input method can search for matching candidate options based on the handwritten pinyin and display the candidate options. This embodiment enables the identification of candidate options by recognizing the user's handwritten pinyin in the handwriting input mode of the input method. Even if the user cannot write a certain character, they can still identify candidate options through handwritten pinyin, thus improving the fluency of the user in the handwriting input mode.

[0098] Reference Figure 2 The diagram illustrates a flowchart of another input method provided in an embodiment of this application. The method may specifically include the following steps:

[0099] Step 201: Obtain the user's handwriting trajectory information.

[0100] Step 202: When handwritten pinyin and handwritten Chinese characters are identified based on the handwritten trajectory information, the handwritten Chinese characters are converted into the corresponding converted pinyin.

[0101] For example, the handwriting kernel of the input method can be invoked to recognize handwriting trajectory information. When the recognized handwriting trajectory information includes both handwritten pinyin and handwritten Chinese characters, the handwritten Chinese characters can be converted into pinyin first.

[0102] Step 203: Find the Chinese character that matches the converted pinyin corresponding to the handwritten pinyin and the handwritten Chinese character.

[0103] For example, the input method's pinyin kernel can be invoked to find Chinese characters that match the converted pinyin corresponding to the handwritten pinyin and the handwritten Chinese characters.

[0104] In this application, the handwritten pinyin and the converted pinyin corresponding to the handwritten Chinese characters can be combined to search for Chinese characters that match the combined pinyin. For example, the user can enter "tāo tiè feast" on the handwritten input interface, and the input method recognizes that the handwritten trajectory information includes the handwritten pinyin "tāo tiè" and the handwritten Chinese characters "feast"; convert "feast" to the converted pinyin "shèng yàn", combine the handwritten pinyin and the converted pinyin to get "tāo tièshèng yàn", and finally find the candidate word "sumptuous feast" that matches "tāo tièshèng yàn".

[0105] For another example, the user can enter "collecting liquid into qiú" on the handwritten input interface, and the input method recognizes that the handwritten trajectory information includes the handwritten Chinese characters "collecting liquid into" and the handwritten pinyin "qiú"; convert "collecting liquid into" to the converted pinyin "jíyèchéng", combine the handwritten pinyin and the converted pinyin to get "jíyèchéng qiú", and finally find the candidate word "many a little makes a mickle" that matches "jíyèchéng qiú", so as to correct the miswritten Chinese character "liquid" to the correct Chinese character "armpit".

[0106] Step 204, determine the first candidate item according to the Chinese characters that match the handwritten pinyin and the converted pinyin.

[0107] Exemplarily, the Chinese characters that match the combined pinyin of the handwritten pinyin and the converted pinyin can be used as the first candidate item, or the words obtained by associating according to the Chinese characters that match the combined pinyin can be used as the first candidate item, or the combined pinyin can be used as the first candidate item.

[0108] Step 205, display the first candidate item.

[0109] The input method can display the found first candidate item in the candidate bar, so that the user can select the first candidate item to be input on the screen. When there are multiple first candidate items, the sorting weights of each first candidate item can be determined respectively, and the first candidate items can be sorted and displayed according to the sorting weights.

[0110] In this embodiment, the input method can acquire the user's handwriting trajectory information. When the handwriting trajectory information includes handwritten pinyin and handwritten Chinese characters, the handwritten Chinese characters are converted into corresponding converted pinyin. The method then searches for Chinese characters that match the converted pinyin, and determines and displays the first candidate word based on the matching character. This embodiment enables the identification of candidate words by recognizing the user's handwritten pinyin and handwritten Chinese characters in the handwriting input mode. Even if the user cannot write a certain character, they can still determine the candidate word through the handwritten pinyin, improving the fluency of the user's handwriting input. Furthermore, by converting the handwritten Chinese characters into converted pinyin and then combining the converted pinyin with the handwritten pinyin, word lookup can be performed based on the combined pinyin. This can correct incorrectly entered Chinese characters, ensuring the accuracy of candidate words.

[0111] Reference Figure 3 The diagram illustrates a flowchart of another input method provided in an embodiment of this application. The method may specifically include the following steps:

[0112] Step 301: Obtain the user's handwriting trajectory information.

[0113] Step 302: When handwritten pinyin and handwritten Chinese characters are identified based on the handwritten trajectory information, search for the Chinese characters that match the handwritten pinyin.

[0114] For example, the handwriting kernel of the input method can be invoked to recognize handwriting trajectory information. When the recognized handwriting trajectory information includes both handwritten pinyin and handwritten Chinese characters, the pinyin kernel of the input method is used to find the Chinese characters that match the handwritten pinyin.

[0115] Step 303: Determine the second candidate based on the Chinese characters matched by the handwritten pinyin and the handwritten Chinese characters.

[0116] For example, based on the input order, words can be formed by matching the handwritten pinyin with the handwritten Chinese characters, resulting in at least one word as a second candidate.

[0117] In one optional embodiment of this application, the method may further include: when handwritten pinyin and handwritten Chinese characters are identified based on the handwritten trajectory information, converting the handwritten Chinese characters into corresponding converted pinyin; searching for Chinese characters that match the converted pinyin corresponding to the handwritten pinyin and the handwritten Chinese characters; and determining a first candidate based on the Chinese characters that match the handwritten pinyin and the converted pinyin.

[0118] In the embodiments of the application, when the identified handwritten trajectory information includes handwritten pinyin and handwritten Chinese characters, two methods can be used to determine the candidate options. One method is to convert the handwritten Chinese characters into converted pinyin, then combine the converted pinyin with the handwritten pinyin, and search for words based on the combined pinyin to obtain the first candidate option. The other method is to form words based on the Chinese characters matched by the handwritten pinyin and the handwritten Chinese characters to obtain the second candidate option. The first and second candidate options may be the same or different.

[0119] Step 304: Display the second candidate.

[0120] When there are multiple second candidates, the ranking weight of each second candidate can be determined, and the second candidates can be sorted and displayed according to the ranking weight.

[0121] In one optional embodiment of this application, step 304 may include the following sub-steps:

[0122] Sub-step S11: When the candidate options include the first candidate option and the second candidate option, and the first candidate option and the second candidate option are not the same, determine the order of the first candidate option and the second candidate option.

[0123] For example, when the first and second candidate options are different, their order can be determined according to a preset sorting strategy. For instance, the input method can statistically analyze the historical click-through rates of candidate options. When the first and second candidate options are different, the historical click-through rates of the first and second candidate options can be obtained separately, and a sorting weight can be determined based on these rates. Alternatively, the sorting weights of the first and second candidate options can be determined based on the context information of the current input box and the current input scenario. In practice, those skilled in the art can determine the sorting weights of the first and second candidate options based on various factors such as the context information of the current input box, the current input scenario, and historical click-through rates. This application does not limit this approach.

[0124] Sub-step S12: Display the first candidate and the second candidate according to the sorting.

[0125] The input method can display the first and second candidate options in the candidate bar according to their order.

[0126] In this embodiment, the input method can acquire the user's handwriting trajectory information; when the handwriting trajectory information includes handwritten pinyin and handwritten Chinese characters, it searches for Chinese characters that match the handwritten pinyin; it determines a second candidate option based on the handwritten pinyin and the handwritten Chinese characters; finally, the input method displays the second candidate option in the candidate bar. This embodiment enables the identification of candidate options by recognizing the user's handwritten pinyin and handwritten Chinese characters in the handwriting input mode of the input method. Even if the user cannot write a certain character, they can still determine the candidate option through handwritten pinyin, improving the user's fluency in the handwriting input mode.

[0127] Reference Figure 4 The diagram illustrates a flowchart of another input method provided in an embodiment of this application. The method may specifically include the following steps:

[0128] Step 401: Obtain the user's handwriting trajectory information.

[0129] Step 402: When handwritten pinyin and handwritten English letters are identified based on the handwritten trajectory information, the handwritten pinyin is selected as a candidate and the handwritten English letters are selected as candidates.

[0130] For example, the handwriting kernel of the input method can be invoked to recognize handwriting trajectory information. When the recognized handwriting trajectory information includes handwritten Pinyin and handwritten English letters, errors are easily made due to their similarity. The user might intend to write Pinyin but it is recognized as handwritten English letters, or vice versa. Therefore, to allow the user to perceive whether an error has been made, when the recognized handwriting trajectory information includes both handwritten Pinyin and handwritten English letters, both can be presented as candidate options for the user to confirm their choice.

[0131] Step 403: Display the candidate options.

[0132] When there are multiple candidate options, the ranking weight of each candidate option can be determined, and the candidate options can be sorted and displayed according to the ranking weight.

[0133] In one optional embodiment of this application, step 403 may include the following sub-steps:

[0134] Sub-step S21: Determine the recognition accuracy of the handwritten pinyin and the handwritten English letters respectively.

[0135] Sub-step S22: Based on the recognition accuracy, determine the order of the handwritten pinyin and the handwritten English letters.

[0136] Sub-step S23: Display the handwritten pinyin and the handwritten English letters according to the order.

[0137] When it is recognized that the handwritten trajectory information includes handwritten pinyin and handwritten English letters, the recognition accuracies of the handwritten pinyin and the handwritten English letters can be determined respectively. Exemplarily, when the handwriting kernel recognizes the handwritten trajectory information, the recognition accuracies of the handwritten pinyin and the handwritten English letters can be determined. The sorting weights can be set according to the recognition accuracy. The higher the recognition accuracy of the candidate item, the greater the set sorting weight; conversely, the lower the recognition accuracy of the candidate item, the smaller the set sorting weight.

[0138] In practice, those skilled in the art can also determine the sorting weights of candidate items according to various factors such as the context information of the current input box and the current input scenario, and the embodiments of the present application do not limit this.

[0139] In the embodiments of the present application, the input method can obtain the handwritten trajectory information of the user; when the input method recognizes that the handwritten trajectory information includes handwritten pinyin and handwritten English letters, the handwritten pinyin can be used as a candidate item, and the handwritten English letters can be used as candidate items; finally, the input method displays the candidate items in the candidate bar.

[0140] The embodiments of the application implement, in the handwriting input mode of the input method, determining candidate items by recognizing the handwritten pinyin and handwritten English letters input by the user. That is, even if the user cannot write a certain character, the candidate items can be determined by handwriting pinyin, which improves the fluency of the user in the handwriting input mode.

[0141] Refer to Figure 5 , which shows a flowchart of steps of another input method provided by the embodiments of the present application. The method may specifically include the following steps:

[0142] Step 501, obtain the handwritten trajectory information of the user.

[0143] Step 502, when handwritten pinyin is recognized according to the handwritten trajectory information, perform error correction processing on the handwritten pinyin to obtain corrected pinyin.

[0144] When the user inputs handwritten pinyin, writing errors may occur. When the recognized handwritten trajectory information includes handwritten pinyin, error correction processing can be performed on the handwritten pinyin to obtain corrected pinyin.

[0145] Exemplarily, the handwritten pinyin input by the user may be determined based on inaccurate pronunciation. For example, due to geographical restrictions, there are many dialects in China, and the pronunciations of people in different places are different. For example, the distinction between retroflex and flat tongue, and between front nasal sound and back nasal sound by people in the south is different from that of people in the north.

[0146] For example, if the handwritten pinyin recognized from the handwritten trajectory information is "leihao", after error correction processing, the corrected pinyin is "nihao", and the candidate "你好" can be obtained according to the corrected pinyin.

[0147] Step 503: Based on the corrected pinyin, find matching candidates.

[0148] Step 504: Display the candidate options.

[0149] The application embodiment realizes that in the handwriting input mode of the input method, by recognizing the handwritten pinyin input by the user, correcting the handwritten pinyin to obtain corrected pinyin, and obtaining matching candidate options based on the corrected pinyin, even if the user cannot write a certain character and misspells the pinyin, the candidate options can be determined by correcting the handwritten pinyin, thereby improving the fluency of the user in the handwriting input mode.

[0150] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of this application are not limited to the described order of actions, because according to the embodiments of this application, some steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also understand that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of this application.
