Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, 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 may be interchanged where appropriate such that embodiments of the application may be practiced otherwise than as specifically illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following is a first explanation of some of the terms or expressions referred to in the claims and specification of the present application.
The formula: is a formula for expressing the relation between several quantities by mathematical symbols in natural science such as mathematics, physics, chemistry, biology and the like.
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 the first information in the case that the first information in the first interface satisfies the 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 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, and a formula editor is not required to be installed and the formula is not required to be edited 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.
The formula display method, the formula display device and the electronic equipment provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof by combining the attached drawings.
The existing input method application only supports outputting text content, but does not support outputting contents such as formulas and icons. Thus, if the user desires to send or view an image of some mathematical formula, chemical equation diagram, formula or equation, such as a sine theorem, rectangular coordinate system, cartesian coordinate system, formula diagram of the chemical equation of copper reacting with concentrated nitric acid; then, the user may trigger downloading and installing the formula design tool first, and then complete formula editing in the formula design tool (e.g., a formula editor) to output the formula; or the user can trigger to display the interface of the browser, then input the search term in the interface of the browser to trigger to search the formulas related to the search term in the browser, and after the result is searched, the user can search the formulas meeting the requirements in the search result.
It can be seen that in one of the above methods, the user needs to trigger and install a specific formula design tool, and needs to manually complete the design of the formula in the tool, which results in complicated interaction, time consumption and inconvenient operation. In the other way, the user needs to switch from the currently displayed interface to the browser interface, and when the retrieved result is more, the user may need to spend a lot of time browsing the retrieved result before finding the formula meeting the requirement, so that the process of outputting the formula may be complicated, the time consumption is long, and the man-machine interaction performance is poor.
In the formula display method provided by the embodiment of the application, when the formula display device displays a first interface (comprising an input method interface and an information input interface); the formula display means may directly display at least one formula corresponding to the first information in the case where the first information in the first interface satisfies the 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 information related to the formula is displayed in the first interface. Therefore, the formula display device can display at least one formula corresponding to the first information directly according to the first information meeting the first condition in the first interface, and a formula editor is not required to be installed and the formula is not required to be edited 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.
The application aims to provide a method for supporting output formulas/pictures in an input method, so that a user can set an education scene and cut into a scene mode in the input method, and the design and generation of mathematical formulas can be rapidly carried out so as to meet the requirement of the user for outputting the mathematical formulas. An education scene is set in the input method, a plurality of modes such as a mathematical mode, a chemical mode and the like are set in the scene, and a design and generation mode of a formula picture of the education scene is newly added on the basis of the text output by the input method.
Alternatively, when using the input method, the user may select "educational scenario" and then the user may select cut-in mode as desired, quickly and accurately find the desired formula by searching.
Further, the user may trigger selection and output of the corresponding formula, and support editing operations on the selected formula before sending the selected formula. And the formula can be converted into an image, and the image can be directly sent to friends or directly saved to an album.
As shown in fig. 1, an embodiment of the present application provides a formula display method, which may include the following steps 101 and 102.
Step 101, the formula display device displays a first interface.
The first interface may include an input method interface and an information input interface.
In the embodiment of the application, the input method interface and the information input interface can be positioned in different areas of the first interface, or the input method interface can be displayed on the input method interface in a superimposed manner, and can be determined according to actual use requirements, and the embodiment of the application is not limited.
Optionally, in the embodiment of the present application, the input method interface is any interface in the input method application, for example, the input method interface may be any possible interface, such as a keyboard interface in the input method application (e.g., interface 22 shown in (a) of fig. 2), and a toolbox interface in the input method application (e.g., interface 23 shown in (b) of fig. 2). 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, videos, and the like. The method can be specifically determined according to actual use requirements, and the embodiment of the application is not limited.
Step 102, the formula display device displays at least one formula corresponding to the first information when the first information in the first interface satisfies the first condition.
Optionally, in an embodiment of the present application, the first information meeting the first condition may include any one of the following: one possible implementation: formula identification in the input method interface is triggered, another possible implementation: information related to the formula is displayed in the first interface.
In the embodiment of the application, the input method application can correspond to N formulas, wherein at least one formula is a formula in the N formulas, and N is a positive integer.
Optionally, in the embodiment of the present application, each of the N formulas may be any one of the following formulas: mathematical formulas, chemical formulas, physical formulas, algorithms, and the like.
Optionally, in the embodiment of the present application, the N formulas may be stored in advance in the application of the input method; or the N formulas may be maintained in a server to which the input method applies. The method can be specifically determined according to actual use requirements, and the embodiment of the application is not limited.
For example, some common education-related knowledge may be pre-stored in the input method application and a small first resource library may be maintained, where the first resource library may include the 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 formulas corresponding to the first information in the first resource library. It can be seen that when the first resource library exists in the input method application, the basic education requirement of the user output formula can be satisfied even without a network.
For example, a second repository that can be updated and perfected continuously can be maintained in the server of the input method application through big data collection, and the second repository can include the N formulas. Thus, when the first information in the first interface meets the first condition, the formula display device can access the server to which the input method is applied, and take the first information as a search word to match formulas online and display the matched formulas.
It can be understood that in the embodiment of the present application, when at least one formula corresponding to the first information is not included in the formulas in the first repository, that is, the formulas in the first repository do not meet the user requirement, the formula display device may request to the cloud (that is, the server to which the input method is applied) to add the repository, or may search for a formula in the online matching second repository, so that more comprehensive education support may be provided.
Optionally, in the embodiment of the present application, the formula display device may display the at least one formula on an input method interface; or superimpose and display the at least one formula on the first interface. The method can be specifically determined according to actual use requirements, and the embodiment of the application is not limited.
The following describes in detail the formula display method provided by the embodiment of the present application through two possible implementations (i.e., one possible implementation and another possible implementation).
Possible implementation manner
Optionally, in an embodiment of the present application, in a possible implementation manner, the first information is a formula identifier in an input method interface.
In the embodiment of the present application, at least one formula corresponding to the first information may specifically be a formula in a formula library indicated by a formula identifier.

Thus, the user may trigger the formula display means to display the formulas indicated by the different formula identifications by inputting the different formula identifications into the at least one formula identification.
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 desires to find a sine theorem formula, the user may input a toolbox identification, as shown in fig. 2 (b), the formula display device may update the keyboard interface 22 as a toolbox interface 23 of the input method application, the toolbox interface 23 includes a "mathematical formula" identification, a "chemical formula" identification, and a "physical formula" identification, and then the user may click on the "mathematical formula" identification, as shown in fig. 2 (c), the formula display device may display a mathematical formula list interface 24 in the input method application, and the mathematical formula list interface 24 includes a search box 25 and at least one general mathematical formula (i.e., at least one formula corresponding to the first information). Thus, as shown in FIG. 2 (c), the user may find the sine theorem formula by sliding up or down on the mathematical formula list interface 24; or as shown in (d) of fig. 2, the user may also trigger the formula display device to quickly and precisely search for the sine theorem formula by inputting the word "sine theorem" in the search box 25 and clicking on "search", and display the sine theorem formula "a: b: c= sinA: sinB: sinC", i.e., the formula related to "sine theorem" in the mathematical formula list interface.
Another possible implementation
Optionally, in an embodiment of the present application, in another possible implementation manner, the first information is information related to a formula displayed in an input method interface or an information input interface.
Optionally, in the embodiment of the present application, the first information may be any word such as a chinese word and an english word related to a formula.
In the embodiment of the application, the formula display device can recognize the information in the first interface through the OCR character recognition technology so as to judge whether the information related to the formula is included in the first interface.
Illustratively, as shown in fig. 3 (a), the information input interface is a chat interface 30 for chatting with a mind, and when the chat interface 30 receives a mind "teacher, can explain a sine theorem? "chat message, the formula display device may display the chat message in the chat interface 30, and recognize the chat message through OCR word recognition technology, and determine that the chat message includes" sine theorem "(i.e., first information) related to the sine theorem formula; then, the formula display device may search a formula library for a formula related to the "sine theorem" and display the searched formula "a: b: c= sinA: sinB: sinC".
For another example, as shown in (b) of fig. 3, the user inputs a character string "zxdl" through the keyboard in the input method interface 31, and triggers the formula display device 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 may include: "zaxideler", "sine theorem", "law of true fragrance", etc.; then the formula display device can recognize the character string and the at least one candidate word through OCR character recognition technology, and determines that the word 'sine theorem' (namely first information) related to the sine theorem formula is displayed in the input method interface; then, the formula display device may search a formula library for a formula related to the "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 which is turned on by default, and a user can trigger the function switch to be turned off manually.
It should be noted that, 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 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 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 an embodiment of the present application, each formula in the at least one formula corresponds to one detail control (for example, a "select" control shown in (b) in fig. 2, and a "more" control in fig. 3), and one detail control may be used to trigger displaying details 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 a detail control corresponding to the first formula.
The first formula may be any one of at least one formula.
In the embodiment of the application, the first input can be the touch input of the detail control by the user.
Step 104, the formula display device responds to the first input and displays a preview editing interface.
The preview editing interface may include details of the first formula.
In the embodiment of the application, the formula display device displays the preview editing interface, and specifically, the formula display device controls the input method application to display the preview editing interface. I.e., the preview editing interface is the 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 device may control the input method application to display the preview editing interface 40, where the theorem definition of the sine theorem (i.e., the detail content of the first formula) is included in the preview editing interface 40.
In the embodiment of the application, the user can input the detail control corresponding to the first formula in at least one formula to trigger the formula display device to display the detail content of the first formula, so that the formula display method provided by the embodiment of the application can simplify the operation process of the output formula and the process of outputting the detail content of the formula. Namely, the formula display method provided by the embodiment of the application can improve the operation convenience and flexibility of the content related to the output formula.
Optionally, in the embodiment of the present application, after the step 104, the formula display method provided in the embodiment of the present application may further include the following steps 105 and 106.
Step 105, the formula display device receives a second input to the preview editing interface.
Optionally, in the embodiment of the present application, the second input is any possible input such as a touch input, a hover input, etc. of the user to 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;
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 the embodiment of the present application, a character type of the character control in the first keyboard corresponds to a character type of the target content.
For example, if the target content is a letter, the character type of the character control in the first keyboard is a letter 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), namely the first keyboard is a Chinese keyboard (for example, 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 number keyboard. If the target content is greek letters, such as "α", the character type of the character control in the first keyboard is greek letter type, i.e., the first keyboard is greek keyboard (i.e., a keyboard including greek letters); if the target content is a formula symbol, for example, "Σ", 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 may display an english keyboard, and may automatically set the english keyboard to a capital lock state; accordingly, if the target content is lower case letters, the formula display device may display an english keyboard and set the english letters in the english keyboard to lower case letters.
Alternatively, in the embodiment of the present application, the above step 105 and step 106 may be specifically implemented in the first manner, the second manner, or the third manner described below.
In the first way, when the second input is an 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 device may display a first keyboard (e.g., keyboard 42 shown in fig. 4 (b)) associated with the last character.
Illustratively, if the user clicks on the keyboard identification 41 in the preview editing interface 40 shown in fig. 4 (a), the target content is the last period of the preview editing interface 40. "so that an edit cursor may be displayed after the last period and the last period may be determined to be the target content, and a pinyin keypad (e.g., keypad 42 shown in fig. 4 (b)) associated with the target content may be displayed.
In the second mode, when the second input is an input to an area of the detail content 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 a content of a position preceding the display position of the editing cursor or a content of a position following the display position of the editing cursor. The method can be specifically 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 device may display an editing cursor at a position subsequent to the kanji "then" (i.e., the target content), and as shown in fig. 4 (b), a pinyin keypad corresponding to the content type of the kanji "then" is displayed.
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 device may display an editing cursor at a position subsequent to the letter "D" and an english keyboard (not shown in the drawing) corresponding to the content type of the letter "D" and automatically set the english keyboard to capital lock.
For another example, if the user is in the preview editing interface 40 shown in fig. 4 (a) the letter "D" and period. "click between", the formula display device 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". ".
Wherein, 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 uppercase-locked; when the target content is a "period", the formula display device may display the period. "content type corresponds to pinyin keypad.
In the embodiment of the application, after the formula display device displays the first keyboard and the editing cursor, the user can trigger updating the display positions of the editing cursor and the first keyboard.
