Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
Some of the nouns or terms referred to in the claims and the specification of the present application will be explained first.
The formula: is a formula for expressing the relationship between several quantities by mathematical symbols in the natural sciences of mathematics, physics, chemistry, biology, etc.
The embodiment of the application provides a formula display method, a formula display device and electronic equipment, wherein a first interface comprising an input method interface and an information input interface is displayed; displaying at least one formula corresponding to first information under the condition that the first information in the first interface meets a first condition; wherein the first information satisfying the first condition includes any one of: the formula identification in the input method interface is triggered, and the information related to the formula is displayed in the first interface. According to the scheme, when the formula identification in the input method interface is triggered or the information related to the formula is displayed in the first interface, namely the first information in the first interface meets the first condition, at least one formula corresponding to the first information can be directly displayed without installing a formula editor or editing the formula in the formula editor, so that the process of outputting the formula can be simplified, and the efficiency of outputting the formula is improved.
The following describes in detail a formula display method, a formula display device, and an electronic device provided in the embodiments of the present application with reference to the accompanying drawings.
The current input method only supports output text content, and does not support output contents such as formulas and icons. Thus, if the user desires to send or view some mathematical formula, chemical equation diagram, image of formula or equation, such as the sine theorem, the rectangular coordinate system, the Cartesian coordinate system, the equation diagram of the chemical equation of copper reacting with concentrated nitric acid; then, the user may first trigger downloading and installing a formula design tool, and then complete formula editing in the formula design tool (e.g., a formula editor) to output the formula; or, the user may first trigger the display of the interface of the browser, then input the search term in the interface of the browser, so as to trigger the search of the formula related to the search term in the browser, and after the search result is obtained, the user may search for the formula meeting the requirement in the search result.
It can be seen that in the above-mentioned one way, the user needs to trigger the installation of a specific formula design tool first, and needs to manually complete the design of the formula in the tool, thereby resulting in complicated interaction, time consumption and inconvenient operation. In another manner, the currently displayed interface needs to be switched to the interface of the browser, and when the retrieved result is large, the user may spend a lot of time browsing the retrieved result before finding the formula meeting the requirement, which may lead to a complicated process of outputting the formula, long time consumption, and poor human-computer interaction performance.
In the formula display method provided by the embodiment of the application, when the formula display device displays a first interface (including an input method interface and an information input interface); the formula display device can directly display at least one formula corresponding to the first information under the condition that the first information in the first interface meets a first condition; wherein the first information satisfying the first condition includes any one of: the formula identification in the input method interface is triggered, and the information related to the formula is displayed in the first interface. Therefore, the formula display device can directly display at least one formula corresponding to the first information according to the first information meeting the first condition in the first interface without installing a formula editor and editing the formula in the formula editor, so that the process of outputting the formula can be simplified, and the efficiency of outputting the formula is improved.
The application aims to provide a method for supporting the output of a formula/picture in an input method, so that a user can set an education scene in the input method, switch in a scene mode and quickly design and generate a mathematical formula, and the requirement of the user for outputting the mathematical formula is met. The method comprises the steps of setting an education scene in an input method, setting a plurality of modes such as a mathematical mode and a chemical mode in the scene, and adding a design and generation mode of formula pictures of the education scene on the basis of outputting texts by the input method.
Alternatively, when using the input method, the user can select "educational scenario" and then the user can select the cut-in mode as desired to find the desired formula quickly and accurately by searching.
Further, the user can trigger the selection and output of the corresponding formula, and the editing operation of the selected formula is supported before the selected formula is sent. And the formula can be converted into an image, and the image can be directly sent to a friend or directly saved in an album.
As shown in fig. 1, an embodiment of the present application provides a formula display method, which may include steps 101 and 102 described below.
The first interface may include an input method interface and an information input interface.
In this embodiment of the application, the input method interface and the information input interface may be located in different areas of the first interface, or the input method interface may be displayed in a superimposed manner on the input method interface, which may be determined specifically according to actual use requirements, and this embodiment of the application is not limited.
Optionally, in this embodiment of the application, the input method interface is any interface in the input method application, for example, any possible interface in the input method interface may be a keyboard interface (such as the interface 22 shown in fig. 2 (a)) in the input method application, a toolbox interface (such as the interface 23 shown in fig. 2 (b)) in the input method application, and the like. The information input interface is any interface capable of inputting information, for example, the information input interface can be any possible interface such as a chat interface, an interface for editing documents, images and videos and the like. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.
And 102, displaying at least one formula corresponding to the first information by the formula display device under the condition that the first information in the first interface meets a first condition.
Optionally, in this embodiment of the application, the first information meeting the first condition may include any one of: one possible implementation: formula identification in the input method interface is triggered, another possible implementation: the first interface displays information related to the formula.
In this embodiment, the input method application may correspond to N formulas, where the at least one formula is a formula of the N formulas, and N is a positive integer.
Optionally, in this embodiment of the present application, each of the N formulas may be any one of the following: mathematical formulas, chemical formulas, physical formulas, algorithms, and the like.
Optionally, in this embodiment of the application, the N formulas may be pre-stored in the input method application; alternatively, the above N formulas may be maintained in a server of the input method application. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.
For example, the input method application may store some commonly used education-related knowledge in advance and maintain a small first resource library, and the first resource library may include the above N formulas, so that when the first information in the first interface satisfies the first condition, the formula display device may search and display the formula corresponding to the first information in the first resource library. It can be seen that when the first repository exists in the input method application, the basic educational needs of the user to output the formula can be satisfied even in the absence of a network.
Illustratively, the server of the input method application can maintain a continuously updated and perfected second resource library through big data collection, and the second resource library can include the above N formulas. In this way, when the first information in the first interface meets the first condition, the formula display device can access the server applied by the input method, match the formula on line by taking the first information as a search word, and display the matched formula.
It can be understood that, in the embodiment of the present application, when the formula in the first repository does not include at least one formula corresponding to the first information, that is, the formula in the first repository does not satisfy the user requirement, the formula display apparatus may request the cloud (that is, the server applied by the input method) to add the repository, and may also match the formula in the second repository online by searching, so that more comprehensive educational support may be provided.
Optionally, in this embodiment of the application, the formula display device may display the at least one formula on the input method interface; or the at least one formula is displayed on the first interface in an overlapping mode. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.

Therefore, the user can trigger the formula display device to display the formulas indicated by different formula identifiers by inputting different formula identifiers in at least one formula identifier.
Illustratively, as shown in fig. 2 (a), the first interface includes a chat interface 21 and a keyboard interface 22 in the input method application, if the user needs to search for a sine theorem formula, the user may identify an input to a tool box, as shown in fig. 2 (b), the formula display apparatus may update the keyboard interface 22 to the tool box interface 23 in the input method application, the tool box interface 23 includes a "mathematical formula" identifier, a "chemical formula" identifier and a "physical formula" identifier, and then the user may click on the "mathematical formula" identifier, as shown in fig. 2 (c), and the formula display apparatus may display a mathematical formula list interface 24 in the input method application, the mathematical formula list interface 24 includes a search box 25 and at least one commonly used formula (i.e., at least one formula corresponding to the first information). Thus, as shown in fig. 2 (c), the user can find the sine theorem formula by sliding up or down on the mathematical formula list interface 24; alternatively, as shown in (d) of fig. 2, the user may also input the word "sine theorem" in the search box 25 and click "search" to trigger the formula display device to quickly and accurately search for the sine theorem formula, and set and display the sine theorem formula "a: b: c: sinA: sinB: sinC", that is, the formula related to the "sine theorem" in the mathematical formula list interface.

Optionally, in this embodiment of the application, the first information may be words in any language, such as chinese words, english words, and the like, related to the formula.
In the embodiment of the application, the formula display device may recognize information in the first interface through an OCR character recognition technology to determine whether the first interface includes information related to the formula.
Illustratively, as shown in fig. 3 (a), the information input interface is a chat interface 30 chatting with xiaoming, and when the chat interface 30 receives "teacher can explain sine theorem? "then the formula display means may display the chat message in the chat interface 30, recognize the chat message by OCR character recognition technology, and determine that the chat message includes the" sine theorem "(i.e. the first information) related to the sine theorem formula; then, the formula display means may search the formula library for a formula related to "sine theorem" and display the searched formula "a: b: c: sinA: sinB: sinC".
For another example, as shown in (b) in fig. 3, the user inputs a character string "zxdl" through a keyboard in the input method interface 31, and the formula display device is triggered to display the character string "zxdl" and at least one candidate word corresponding to the character string "zxdl" on the input method interface, where the at least one candidate word specifically includes: "zaxideler", "sine theorem", "true fragrance law", etc.; then the formula display device can identify the character string and the at least one candidate word through an OCR character recognition technology, and determine that a word 'sine theorem' (namely first information) related to the sine theorem formula is displayed in the input method interface; then, the formula display means may search the formula library for a formula related to "sine theorem" and display the searched formula "a: b: c: sinA: sinB: sinC".
In the embodiment of the application, the input method setting interface of the input method application comprises an "education scene" function switch, the "education scene" function switch is turned on by default, and of course, a user can also manually trigger the function switch to be turned off.
In the embodiment of the present application, the formula input method provided in the embodiment of the present application is executed when the "education scene" function switch is turned on.
In the formula display method provided by the embodiment of the application, when the formula identifier in the input method interface is triggered or the information related to the formula is displayed in the first interface, that is, the first information in the first interface meets the first condition, at least one formula corresponding to the first information can be directly displayed without installing a formula editor and editing the formula in the formula editor, so that the process of outputting the formula can be simplified, and the efficiency of outputting the formula can be improved.
Optionally, in this embodiment of the application, each formula in the at least one formula corresponds to a detail control (for example, a "select" control shown in (b) in fig. 2, or a "more" control in fig. 3), and one detail control may be used to trigger display of detail content of the formula corresponding to the detail control. After the step 102, the formula display method provided in the embodiment of the present application may further include the following steps 103 and 104.
Step 103, the formula display device receives a first input of the detail control corresponding to the first formula.
Wherein the first formula may be any one of the at least one formula.
In this embodiment of the application, the first input may be a touch input of the user to the detail control.
And 104, responding to the first input by the formula display device, and displaying a preview editing interface.
The preview editing interface can include the detailed content of the first formula.
In this embodiment, the formula display device displays the preview editing interface, which may be specifically a preview editing interface displayed by the formula display device for controlling the input method application. Namely, the preview editing interface is an interface in the input method application.
Illustratively, as shown in (b) of fig. 3, the user may click on the "more" control corresponding to the sine theorem formula, and then as shown in (a) of fig. 4, the formula display apparatus may control the input method application to display the preview editing interface 40, where the theorem definition of the sine theorem (i.e., the detailed content of the first formula) is included in the preview editing interface 40.
In the embodiment of the application, because the user can trigger the formula display device to display the detailed content of the first formula by inputting the detailed control corresponding to the first formula in the at least one formula, the formula display method provided by the embodiment of the application can simplify the operation process of outputting the formula and the process of outputting the detailed content of the formula. The formula display method provided by the embodiment of the application can improve the operation convenience and flexibility of outputting the contents related to the formula.
Optionally, in this embodiment of the present application, after the step 104, the formula display method provided in this embodiment of the present application may further include the following steps 105 and 106.
And 105, receiving a second input to the preview editing interface by the formula display device.
Optionally, in this embodiment of the application, the second input is any possible input such as a touch input, a hover input, and the like of the user on the preview editing interface.
Step 106, the formula display device responds to the second input, displays an editing cursor in the preview editing interface, and displays a first keyboard associated with the target content;
wherein the target content is determined according to the display position of the editing cursor. Specifically, the target content may be content located at a position subsequent to the display position of the editing cursor, or may be content located at a position previous to the display position of the editing cursor.
In the embodiment of the application, the first keyboard is specifically associated with the content type of the target content.
Optionally, in this embodiment of the present application, the character type of the character control in the first keyboard corresponds to the character type of the target content.
Exemplarily, if the target content is an alphabet, the character type of the character control in the first keyboard is an alphabet type, that is, the first keyboard is an english keyboard; if the target content is Chinese characters, the character type of the character control in the first keyboard is Chinese pinyin (or Chinese character type), that is, the first keyboard is a Chinese keyboard (such as a pinyin keyboard); if the target content is a number, the character type of the character control in the first keyboard is a number type, namely the first keyboard is a numeric keyboard. If the target content is a greek letter, such as "α", the character type of the character control in the first keyboard is a greek letter type, that is, the first keyboard is a greek keyboard (i.e., a keyboard including greek letters); if the target content is a formula symbol, e.g., "∑", the character type of the character control in the first keyboard is a formula symbol type, i.e., the first keyboard is a formula symbol keyboard.
Further, when the target content is a letter, if the target content is a capital letter, the formula display device can display the english keyboard and can automatically set the english keyboard to be in a capital locking state; accordingly, if the target content is a lower case letter, the formula display apparatus may display the english keyboard and set the english letter in the english keyboard to a lower case.
Alternatively, in this embodiment of the application, the step 105 and the step 106 may be specifically implemented by the following first mode, second mode, or third mode.
First, when the second input is input to a keyboard identifier (such as the keyboard identifier 41 shown in fig. 4) in the preview editing interface, the display position of the editing cursor is the first position after the last character displayed in the preview editing interface, and the target content is the last character. Thus, the formula display apparatus may display a first keyboard (e.g., the keyboard 42 shown in fig. 4 (b)) associated with the last character.
Illustratively, if the user clicks on the keyboard flag 41 in the preview editing interface 40 shown in (a) in fig. 4, the target content is the last period "of the preview editing interface 40. "so that the editing cursor may be displayed after the last period and the last period is determined as the target content, and a pinyin keypad (e.g., keypad 42 shown in fig. 4 (b)) associated with the target content is displayed.
In the second mode, when the second input is an input to a region where detailed content is displayed in the preview editing interface, the display position of the editing cursor is an input position of the second input in the preview editing interface, and the target content may be content at a position before the display position of the editing cursor or may be content at a position after the display position of the editing cursor. The method can be determined according to actual use requirements, and the embodiment of the application is not limited.
For example, if the user clicks on the kanji then in the preview editing interface 40 shown in fig. 4 (a), the formula display apparatus may display the editing cursor at a position subsequent to the kanji then (i.e., the target content), and display a pinyin keypad corresponding to the content type of the kanji then as shown in fig. 4 (b).
For another example, if the user clicks on the letter "D" (i.e., the target content) in the preview editing interface 40 shown in fig. 4 (a), the formula display apparatus may display an editing cursor at a position subsequent to the letter "D" and display an english keyboard (not shown in the drawing) corresponding to the content type of the letter "D" and automatically set the english keyboard as capital lock.
For another example, if the user is previewing the letters "D" and period "in the editing interface 40 shown in fig. 4 (a). "between clicks", the formula display means may display the editing cursor at a position subsequent to the letter "D", in which case the target content may be the letter "D" or a period adjacent to the letter "D". ".
When the target content is the letter "D", the formula display device may display an english keyboard (not shown in the figure) corresponding to the content type of the letter "D", and automatically set the english keyboard to be capital-locked; when the target content is "period", the formula display device may display the period ". "content type of the corresponding pinyin keyboard.
In the embodiment of the application, after the formula display device displays the first keyboard and the editing cursor, a user can trigger to update the display positions of the editing cursor and the first keyboard.
It can be understood that, in the embodiment of the present application, after the formula display apparatus displays the first keyboard and the editing cursor, the user may edit the detailed content of the first formula according to the actual use requirement of the user.
It can be understood that, in an actual implementation, the first keyboard may also be a default keyboard of the system or a keyboard displayed last time, and may be determined specifically according to an actual use requirement, and the embodiment of the present application is not limited.
In the embodiment of the application, the character type of the character control in the first keyboard corresponds to the character type of the target content, so that a user can directly input the character control in the first keyboard to trigger the formula display device to edit the target content without triggering a switching keyboard, the flexibility and convenience of editing the detailed content of the formula can be further improved, and the human-computer interaction performance is improved.
In the embodiment of the application, the user can trigger the formula display device to display the first keyboard and the editing cursor through the second input, so that the user can edit the detailed content of the first formula based on the editing cursor and the first keyboard. Therefore, the man-machine interaction performance can be further improved.
Optionally, in this embodiment of the present application, after the step 104, the display method provided in this embodiment of the present application may further include the following step 107 and step 108.
And step 107, the formula display device receives a third input to the preview editing interface.
And step 108, responding to the third input by the formula display device, acquiring a screen capture image of the preview editing interface, and executing a first operation corresponding to the third input on the screen capture image.
Wherein the first operation may comprise at least one of: saving the screenshot image and sending the screenshot image through the information input interface.
Optionally, in this embodiment of the application, the formula display apparatus may acquire a screenshot image of the preview editing interface by using a long screenshot function.
Optionally, in this embodiment of the application, the third input is a voice input, an input of a preset gesture, or may be an input of a preset control in the preview editing interface.
