The following describes embodiments of the present application in detail.

Referring to fig. 2, fig. 2 is a schematic flowchart of a font switching method provided in an embodiment of the present application, and the method is applied to an electronic device. The font switching method comprises the following steps:

s201, when detecting that the currently displayed application interface displays text information, the electronic equipment determines the font and the display density of the text information.

When the electronic device uses a different application interface, different text information is displayed, and the text information may include a font, a font size, a display area, display content, and the like of the displayed text. Generally, the text information is displayed by using a default font, and the default font may be a default font configured by the electronic device or a default font configured by the application.

The font and the display density of the text information can be determined according to the text information, so that whether the font switching method provided by the embodiment of the application is executed or not is determined, but when the number of displayed texts is small, or the font size is small, or the display area of the texts is remote (corner area of a screen), or the display area is small, the font switching is performed, possibly, a user cannot obviously feel that the fonts are switched, so that the text information can be further set, and when the text information meets certain preset conditions, the font and the display density of the text information are determined.

S202, when the electronic equipment detects that the font is a default font and the display density is smaller than a target preset density threshold value, a pre-stored user handwriting font resource library is obtained, the user handwriting font resource library is a set of characters which are generated through a pre-trained artificial intelligent AI font model and are matched with the handwriting habits of the user, and the AI font model is obtained after being trained through handwriting font data input by the user.

When the electronic equipment detects that the font of the text information is the default font and the display density of the text information is smaller than the target preset density threshold value, the font switching of the font of the text information can be determined.

The method comprises the steps of obtaining a pre-stored user handwritten font resource library, wherein each type of font corresponds to one font resource library, and the font resource libraries comprise specific character images corresponding to each character, namely character sets comprising the type of font. The user handwriting font can be obtained by an Artificial Intelligence (AI) model, and a set of characters matched with the handwriting habit of the user is generated by the pre-trained AI font model, namely the user handwriting font resource library, so that when the font is switched, the corresponding characters can be obtained from the user handwriting font resource library, and the font is switched for the characters.

The AI model can be obtained after the handwritten font data input by the user are trained, the handwritten font data input by the user comprise some characters handwritten by the user, and the rules of the handwritten characters of the user can be obtained by the AI model according to the characters handwritten by the user, so that other characters handwritten by the user can be obtained, and a user handwritten font resource library can be generated.

S203, the electronic equipment switches the font of the character information into the user handwritten font through the user handwritten font resource library.

When the font switching operation of the user is detected, or in a preset scene set by the user and needing font switching, the font of the character information can be switched into the user handwritten font according to the user handwritten font resource library and the character information.

It can be seen that, in this application embodiment, electronic equipment at first when detecting the application interface display of current demonstration has the text information, confirms the typeface and the display density of text information, secondly, is detecting the typeface is acquiescent typeface, just when the display density is less than the target and predetermines the density threshold value, acquires the user that prestores and writes by hand the typeface resource bank, the user writes by hand the collection of the characters of typeface resource bank for the matching user's handwriting custom that artificial intelligence AI typeface model through the pre-training generated, AI typeface model obtains after training through the handwritten typeface data of user input, finally, through the user writes by hand the typeface resource bank will the typeface of text information switches into the user's handwriting typeface. Because electronic equipment can confirm the typeface and the display density of characters in the information according to the literal information of the application interface that shows at present to can be when detecting the typeface of literal information for acquiescence typeface, and the display density is less than and predetermines the density threshold value, acquire the user that prestores and write by hand the typeface resource storehouse, thereby write by hand the typeface resource storehouse through the user and switch the typeface of literal information into user's typeface of writing by default typeface, make the typeface setting more individualized, be favorable to improving user's reading experience.

In one possible example, the determining the display density of the text information includes: determining a first display area and a first character number corresponding to the character information in the application interface; acquiring pre-stored user handwritten font template characters, and selecting target user handwritten font template characters with the display area being the first display area from the user handwritten font template characters, wherein the fonts of the user handwritten font template characters are the user handwritten fonts; determining a second character number corresponding to the target user handwritten font template characters; and determining the display density according to the ratio of the first character number to the second character number.

The method comprises the steps of determining a first display area and a first character number of character information displayed by the application interface, wherein the first display area can be the display area of all character information, the first character number corresponds to the number of all characters displayed, the first display area can also be the display area of the selected character information in a certain area, and the first character number corresponds to the character number of the display area.

The method comprises the steps of obtaining pre-stored user handwritten font template characters, wherein character fonts in the user handwritten font template characters are user handwritten fonts, and the size of the character fonts is the same as that of characters in character information. Selecting target user handwritten font template characters with the display area as the first display area from the handwritten font template characters, determining the second character number corresponding to the handwritten font template characters of the user, and determining the display density of characters in character information according to the first character number and the second character number.

For example, the text information with the display area of the first display area includes 300 characters, and the target user handwritten font template characters with the display area also being the first display area only have 200 characters, so that it is obvious that, by using the user handwritten font template characters as a standard, it is detected that the display density of the text information is 1.5 times of that of the user handwritten font template, and the more characters are displayed in the text information, the greater the display density of the text information is.

It can be seen that, in this example, the user handwriting font template is used as a standard, because the size of the text font in the user handwriting font template is the same as the size of the text font in the text information, and the distance between the texts is a standard distance that is set by the user or a system and is suitable for the user to read, according to the number of the texts in the text information with the same display area and the number of the texts in the user handwriting font template, the ratio between the number of the texts and the number of the texts in the text information with the same display area is determined to determine the display density of the text information, which is beneficial to determining whether the text information of the current display interface meets the condition.

In one possible example, the determining the display density of the text information includes: determining a first distance between characters displayed by the application interface; and determining the display density of the text information according to the first distance.

In this example, the first interval between the characters displayed on the application interface is determined, and the display density of the character information is determined according to the size of the first interval, in general, the larger the interval is, the smaller the character density is, the smaller the interval is, and the larger the character density is, and whether the display density of the character information meets the condition of font switching is determined according to the interval, which is beneficial to improving the processing efficiency.

In one possible example, the determining the display density of the text information according to the first distance includes: acquiring pre-stored user handwritten font template characters, and determining a second space between characters in the user handwritten font template characters; determining the display density according to a ratio between the second pitch and the first pitch.

The electronic equipment stores user handwritten font template characters, the user handwritten font template characters comprise user handwritten fonts, the user handwritten font template characters have the same font size, the space between the characters can be used for a user to read, and the space can reduce the reading fatigue.

The method comprises the steps of obtaining pre-stored user handwritten font template characters, determining a second interval between characters in the user handwritten font template characters, and determining display density according to the ratio of the first interval to the second interval, wherein the font size of the pre-stored user handwritten font template characters is the same as the font size of character information. The first and second pitches may be left-right pitches between letters, or up-down pitches.

As can be seen, in this example, according to the second distance between the characters in the standard user handwritten font template characters and the first distance between the character information displayed on the current application interface, the ratio between the second distance and the first distance is determined, where the larger the ratio is, the greater the display density of the description character information is, and the smaller the ratio is, the smaller the display density of the description character information is.

In one possible example, the switching the font of the text information into a handwritten font through the user handwritten font resource library includes: determining a second display area corresponding to the text information after the font of the text information is switched from the default font to the user handwritten font; when detecting that the difference value between the second display area and the first display area is larger than a first preset threshold value, adjusting the text information of the handwritten font of the user, so that the difference value between the adjusted display area of the text information and the first display area is smaller than the first preset threshold value.

The handwriting fonts of all users are different, the characters of the handwriting fonts of some users are possibly longer, the characters of the handwriting fonts of some users are possibly wider, but after the characters in the character information are switched to the handwriting fonts of the users from default fonts, the left-right spacing and the up-down spacing between the characters are not changed, because the character information after the characters are switched possibly corresponds to a second display area, when the fact that the difference between the second display area and the first display area is larger than a first preset threshold value is detected, the adjusted character information can be adjusted, and therefore the difference between the display area of the adjusted character information and the first display area is smaller than the first preset threshold value.

The adjustment manner may be to scale the font information after switching, and scale the display area from the second display area to the first display area, which is not limited herein.

It can be seen that, in this example, after the font of the text information is switched from the default font to the user handwritten font, the second display area corresponding to the text information is detected, and when the difference between the detected second display area and the first display area before the font is switched is greater than the first preset threshold, the text information is adjusted so that the display of the text information does not affect the visual experience of the user.

In one possible example, the switching the font of the text information into a handwritten font through the user handwritten font resource library includes: acquiring a historical use record of an application scene corresponding to the application interface; determining the number of times of receiving font switching instructions in the application scene according to the historical usage record; and when the frequency is detected to be greater than a second preset threshold value, switching the font of the text information into the user handwriting font.

The electronic equipment can also obtain a historical use record of an application scene corresponding to the current application interface, determine the number of times of the received font switching instruction in the application scene according to the historical use record, and directly switch the font of the text information into the user handwritten font when the detected number of times is greater than a second preset threshold value, so that the user is not required to execute the operation of switching the font.

As can be seen, in this example, the number of times that the font switching instruction is received in the application scene corresponding to the application interface is determined, and when the number of times exceeds the second preset threshold, it indicates that the user is more likely to use the user handwritten font to display the text information in the application scene, so that when the electronic device enters the application scene, the font of the text information is directly switched to the user handwritten font, thereby omitting the manual font switching by the user.

In one possible example, the method further comprises: when the current application is detected to be a preset application, determining a first preset density threshold value set corresponding to the application; determining an application scene of the application according to the application interface of the application; and searching a mapping relation between a preset application scene and a preset density threshold value, and determining a target preset density threshold value corresponding to the application scene in the first preset density threshold value set.

The method comprises the steps of obtaining character information displayed under a plurality of application scenes by a preset application, and training the character information through an AI font model according to the displayed character information to obtain a preset density threshold value set of the preset application, wherein each preset density threshold value in the preset density threshold value set corresponds to one application scene.

As can be seen, in this example, in different application scenes of the same application, the preset density threshold corresponding to each application scene is different, and the first preset density threshold set corresponding to the current application is determined, so that the target preset density threshold of the application scene corresponding to the current interface in the first preset density threshold set is determined, and by determining whether the display density of the text information is smaller than the target preset density threshold, it is beneficial to determine whether font switching operation is required.

In one possible example, the method further comprises: when the electronic equipment is detected to start a handwriting input method, acquiring characters handwritten by a user; and training the characters handwritten by the user through the pre-trained artificial intelligence AI font model to obtain the handwritten characters of the user.

As can be seen, in this example, the pre-trained artificial intelligence AI font model may determine the resource library of the handwritten fonts of the user according to the handwritten font data input by the user, for example, when it is detected that the electronic device starts a handwriting input method, the handwritten characters of the user are obtained, the images of the handwritten characters may be obtained, the handwritten characters of the user are trained through the AI model, and the resource library of the handwritten fonts of the user is obtained according to a part of the characters handwritten by the user.

In one possible example, the method further comprises: shooting a target picture through a camera, wherein the target picture is a shot picture containing characters written by a user through handwriting; extracting characters of the user handwritten fonts from the target pictures, training the characters of the user handwritten fonts through the pre-trained artificial intelligence AI font model, and determining the user handwritten font resource library.

As can be seen, in this example, the user handwritten font resource library may be obtained by obtaining handwritten font data of the user, for example, taking a target picture including characters of the user handwritten font, extracting the characters of the user handwritten font from the target picture, and training the characters of the user handwritten font through a pre-trained artificial intelligence AI font model.

And S303, after the electronic equipment determines to switch the font of the text information from the default font to the user handwritten font, the electronic equipment determines a second display area corresponding to the text information.

S304, when detecting that the difference value between the second display area and the first display area is larger than a first preset threshold value, the electronic device adjusts the text information of the handwritten font of the user, so that the difference value between the adjusted display area of the text information and the first display area is smaller than the first preset threshold value.

It can be seen that, in this application embodiment, electronic equipment at first when detecting the application interface display of current demonstration has the text information, confirms the typeface and the display density of text information, secondly, is detecting the typeface is acquiescent typeface, just when the display density is less than the target and predetermines the density threshold value, acquires the user that prestores and writes by hand typeface resource bank, the collection of the characters of matching user's handwriting custom that user's manual intelligence AI typeface resource bank produced through the artificial intelligence AI typeface model of training in advance, AI typeface model obtains after training through the handwritten typeface data of user input, finally, through user's handwritten typeface resource bank will the typeface of text information switches into user's handwritten typeface. Because electronic equipment can confirm the typeface and the display density of characters in the information according to the literal information of the application interface that shows at present to can be when detecting the typeface of literal information for acquiescence typeface, and the display density is less than and predetermines the density threshold value, acquire the user that prestores and write by hand the typeface resource storehouse, thereby write by hand the typeface resource storehouse through the user and switch the typeface of literal information into user's typeface of writing by default typeface, make the typeface setting more individualized, be favorable to improving user's reading experience.

In addition, after the font of the text information is switched from the default font to the handwritten font of the user, a second display area corresponding to the text information is detected, and when a difference value between the detected second display area and a first display area before the font is switched is larger than a first preset threshold value, the text information is adjusted, so that the display of the text information does not influence the visual experience of the user.
