The user interface may be an interface of an application program that learns ancient texts.

A canvas area may be displayed on a user interface of the user terminal, wherein the canvas area may be a canvas for tracing created using a RenderTexture. A clearing control can also be displayed on the user interface and used for recording image data when the canvas area is initialized so as to initialize the canvas. The user interface can also be displayed with a cancel control for canceling at least one operation executed by the user, wherein the cancel times can be flexibly set according to the actual situation. It should be noted that the processor may store historical image data drawn by the user, and when the user clicks a cancel control, the processor may read the stored historical image data, thereby implementing the cancel function.

The processor of the user terminal may call a Graphics Processing Unit (GPU), and copy pixel information of an ancient character picture corresponding to a simplified character stored in a memory of the user terminal according to the simplified character input by the user and the specified simplified character set by the course, so as to obtain the character to be traced displayed in the canvas area. The pixel information of the ancient character picture can be understood as color points of the ancient characters in the ancient character picture, and the color points are the most basic units of the ancient character picture.

It should be noted that the GPU resource performance can be directly called in the embodiment of the present application, the performance resource of the processor of the user terminal is not occupied, and the drawing fluency of the user is improved.

The characters to be traced can be displayed in the center of the canvas area, and can also be displayed in the positions under consideration in the canvas area. The font size of the character to be traced can be determined according to the size of the canvas area, for example, the font size of the character to be traced occupies two thirds of the area of the canvas area. And the color of the character to be traced can be a light color system, so as to facilitate tracing by a user, for example, the character to be traced is presented in light gray, and the present position and the color of the character to be traced are not particularly limited in the embodiment of the present application. The user can draw directly above the character to be traced, so that tracing is realized.

In one embodiment, the characters to be traced can include characters of any one of oracle, golden, seal (e.g., small seal) and drumstick characters.

120: and receiving a tracing result of the character to be traced in the canvas area by the user.

Specifically, the user configures configuration information of the brush through a touch object (such as a finger or a mouse), and the configuration information may include the color and thickness of the brush and the shape of the pen point. Then acquiring the position information of the user clicked in the canvas area by using a painting pen; converting the position information into a corresponding pixel area; and dyeing each first pixel point in the pixel region by applying the color configured by the user to the painting brush, thereby realizing the drawing function of the painting brush. Finally, repeatedly executing the step of' acquiring the position information of the brush clicked in the canvas area by the user application; converting the position information into a corresponding pixel area; and dyeing each first pixel point in the pixel region by applying the color configured by the user to the painting brush until a tracing result is obtained.

That is, the color of the brush configuration is the color of the rendering tracing result.

Further, the color of the tracing result input by the user and the color of the character to be traced may be different, for example, the character to be traced is light gray, and the color of the tracing result input by the user may be yellow, so as to extract the number of pixel points of the tracing result and the character to be traced in the subsequent process, thereby calculating the tracing result.

130: and obtaining a tracing score based on the tracing result and the character to be traced.

Specifically, a processor of the user terminal evaluates similarity between a tracing result input by the user and the character to be traced, and acquires a tracing score based on a preset similarity standard, wherein the tracing score is used for indicating whether the user traces the character, and the closer the user traces the character to be traced, the higher the tracing score.

Fig. 2 is a flowchart illustrating a method for assisting learning according to another exemplary embodiment of the present application. The embodiment of fig. 2 is a further definition of step 120 of the embodiment of fig. 1. As shown in fig. 2, this step 120 further includes the following.

210: configuration information for a stylus input by a user is received.

In one embodiment, the configuration information includes a color.

Specifically, configuration information for a stylus input by a user applying a touch (e.g., a finger or a mouse) is received. The configuration information may include related parameters such as color, thickness (i.e. size of the brush), shape of the pen point, and drawing frequency of the brush.

It should be noted that, in the embodiment of the present application, a basic picture with a transparent gradual transition from the center to the periphery of a circle may be used as a basic style of a brush (or a brush tip) displayed on a user interface, and the basic style presented by the brush may be changed to other styles of graphics.

220: step a: and acquiring the position information of the user application brush clicked in the canvas area.

Specifically, the user interface may establish a coordinate system, and an origin of the coordinate system may be an upper left corner of the user interface or a center of the user interface.

In an embodiment, a processor of the user terminal may obtain real-time position information of a click input of the user application brush in the canvas area, and convert the position information into coordinate information of the canvas area, wherein the coordinate information is obtained based on a coordinate system established by the user interface.

It should be noted that when the processor detects that the user does not click on the canvas area, the user cannot perform the copy operation.

230: step b: and determining a pixel area corresponding to the position information.

In particular, the canvas area may establish UV coordinates. The UV coordinate is a two-dimensional plane, wherein U represents the horizontal direction, V represents the vertical direction, and any pixel point of the character to be traced on the canvas area can be defined through the UV coordinate. It should be noted that, at this time, the canvas area containing the characters to be copied may be regarded as a two-dimensional picture, and the UV coordinate may define any one pixel point of the characters to be copied in the canvas area.

In one embodiment, the position information obtained by clicking the canvas area by the user is converted into the coordinate information of the canvas area, wherein the coordinate information is determined based on a coordinate system established by the user interface. It should be noted that the coordinate information can be understood as a relatively local coordinate point of the canvas area.

Further, the coordinate information of the relative local part of the canvas area is converted into a pixel area obtained on the canvas area based on the UV coordinate, wherein the pixel area can be UV position information used for representing the pixel area corresponding to the position information.

240: step c: and dyeing each first pixel point in the pixel region by using the color to obtain a pixel dyeing result.

Specifically, according to the color configured by the paintbrush, each first pixel point in the obtained pixel region is dyed to obtain a pixel dyeing result. For example, when the color of the configuration of the pen input by the user is yellow, the acquired pixel dyeing result is also yellow.

It should be noted that, in the embodiment of the present application, the rendering calculation may be replaced on the canvas area through the GPU, so as to implement the basic function of drawing with a brush.

250: and repeating the steps a to c until a tracing result is obtained.

In one embodiment, the tracing result includes a plurality of pixel staining results.

Specifically, repeatedly executing steps a to c may be understood as a process in which the user continuously draws the text to be traced until a tracing result of the tracing completed by the user is obtained. That is, the tracing result is composed of a plurality of pixel dyeing results.

In an embodiment, after the user clicks a "submit" control displayed on the user interface, it indicates that the user has finished tracing the character to be traced, and at this time, the content displayed in the canvas area is the tracing result input by the user.

Therefore, the position information clicked by the user is converted into the pixel region information, and each pixel point (first pixel point) in the pixel region is dyed, so that the drawing function of the painting brush is realized.

Fig. 3 is a flowchart illustrating a method for assisting learning according to another exemplary embodiment of the present application. The embodiment of fig. 3 is an example of the embodiment of fig. 1, and the same parts are not repeated herein, and the differences are mainly described here. As shown in fig. 3, the method of assisted learning includes the following steps.

It should be noted that the basic principle of the drawing function of the brush pen is to draw a set brush point picture continuously at a small distance interval to form a line. It is conventional practice in the prior art to capture the position of a touch object (e.g., a mouse or finger) every frame, and to draw a graphic once per frame. However, the above method results in a low operation frame rate, and when a user manipulates a mouse or moves a finger, the moving speed of each frame is different, so that discontinuous rendering occurs. To this end, the embodiments of the present application provide the following methods.

310: acquiring a first frame image and a second frame image when a user draws a character to be traced.

In one embodiment, the first frame image and the second frame image are two consecutive frame images.

Specifically, two continuous frame images, namely a first frame image and a second frame image, of a user when drawing a character to be traced are acquired. The first frame image and the second frame image may be any two consecutive frames of images, and the first frame image and the second frame image are not particularly limited in this embodiment of the application.

320: and acquiring a first position drawn by the brush in the first frame image and a second position drawn by the brush in the second frame image.

Specifically, a first position and a second position drawn by a brush in two continuous frames of images are respectively obtained.

330: and filling at least one second pixel point between the first position and the second position by using the color so as to realize the function of continuous drawing.

Specifically, at least one second pixel point which is not dyed and located between the first position and the second position drawn by the brush is filled according to the color configured by the brush, so that the function of continuous drawing is achieved.

It should be noted that, in the embodiment of the present application, it may be understood that drawing information to be supplemented is uniformly filled according to the distance between the positions drawn by the brushes in the two frames before and after, and then drawing is performed.

Therefore, in the embodiment of the application, the distance interval between the front point and the rear point drawn by the brush pen in two continuous frames of images is supplemented in the drawing process, so that the continuous drawing function of the brush pen is realized.

Fig. 4 is a flowchart illustrating a method for assisting learning according to still another exemplary embodiment of the present application. The embodiment of fig. 4 is a further definition of step 130 of the embodiment of fig. 1. As shown in fig. 4, this step 130 further includes the following.

410: and acquiring the number of third pixel points included in the character to be traced.

Specifically, the text to be traced can be displayed in light gray within the canvas area, and in order to facilitate the user tracing the text to be traced, the text to be traced can be displayed in a bolded manner. That is, the text to be traced may include a plurality of third pixel points.

It should be noted that a pixel point (e.g., the third pixel point) can be understood as a color point constituting the character to be copied, and is the most basic unit constituting the character to be copied.

In an embodiment, a canvas area presented by the user interface may be provided with a function of acquiring the number of pixels of a specified color. The canvas area may obtain the number of third pixel points corresponding to the characters to be traced according to the color (for example, light gray) of the characters to be traced, where the number of the third pixel points is the total number of the pixel points corresponding to the characters to be traced.

420: and acquiring the quantity of fourth pixel points at the positions corresponding to the tracing result and the character to be traced and the quantity of fifth pixel points overflowing the character part to be traced.

Specifically, the tracing result input by the user includes a plurality of pixel points, where the plurality of pixel points of the tracing result may include a plurality of fourth pixel points and a plurality of fifth pixel points, that is, color points constituting the tracing result may be the plurality of fourth pixel points and the plurality of fifth pixel points.

The fourth pixel point can be a pixel point of a part corresponding to the character to be traced in the tracing result, namely a pixel point tracing above the character to be traced. The fifth pixel point can be a pixel point exceeding the character to be traced in the tracing result, namely a pixel point overflowing the character part to be traced.

In an embodiment, a canvas area presented by the user interface may be provided with a function of acquiring the number of pixels in a specified color, detect a specified color input by the user (i.e., a color input when the brush is configured), and acquire information on the number of pixels in the canvas area containing the color. That is to say, the canvas area can obtain the number of the fourth pixel points located above the character to be traced according to the color of the tracing result, and obtain the number of the fifth pixel points overflowing the character part to be traced.

430: and acquiring the tracing score based on the number of the third pixel points, the number of the fourth pixel points and the number of the fifth pixel points.

Specifically, determining the tracing coverage rate based on the ratio of the number of the fourth pixel points to the number of the third pixel points; and determining the tracing overflow rate based on the number of the fifth pixel points and the number of the total pixel points of the tracing result (namely the sum of the number of the fourth pixel points and the number of the fifth pixel points). And determining the tracing score according to the tracing coverage rate and the tracing overflow rate.

It should be noted that, for the detailed description of step 430, please refer to the record of the embodiment in fig. 5 for details, which are not described herein again.

Therefore, the method and the device for determining the copy score can determine the copy score by acquiring the pixel points of the character to be copied and the pixel points of the copy result, and the accuracy of similarity discrimination is improved.

Fig. 5 is a flowchart illustrating a method for assisting learning according to still another exemplary embodiment of the present application. The embodiment of fig. 5 is a further definition of step 430 in the embodiment of fig. 4. As shown in fig. 5, this step 130 further includes the following.

510: and determining the tracing coverage rate according to the ratio of the number of the fourth pixel points to the number of the third pixel points.

Specifically, the tracing coverage rate is determined according to the ratio of the number of fourth pixel points located above the character to be traced in the tracing result to the number of third pixel points of the character to be traced. That is to say, the tracing coverage is obtained by calculating the numerator which is the number of the fourth pixel points and the denominator which is the number of the third pixel points.

520: and determining the tracing overflow rate according to the ratio of the number of the fifth pixel points to the sum of the number of the fourth pixel points and the number of the fifth pixel points.

Specifically, the sum of the number of the fourth pixel points and the number of the fifth pixel points may be understood as the number of total pixel points of the tracing result. And determining the tracing overflow rate according to the ratio of the number of fifth pixel points overflowing the character to be traced in the tracing result to the number of total pixel points of the tracing result. That is to say, the tracing overflow rate is obtained by calculating the numerator which is the number of the fifth pixel points and the denominator which is the number of the total pixel points of the tracing result.

530: and determining the tracing achievement based on the tracing coverage rate and the tracing overflow rate.

Specifically, according to the tracing coverage rate and the tracing overflow rate, tracing scores are obtained according to a preset similarity standard. The preset similarity criterion may be a first value corresponding to the tracing coverage and a second value corresponding to the tracing overflow rate, wherein the first value is a product of the tracing coverage and 1.05, and the second value is a product of the tracing overflow rate divided by 3 times 100.

In one embodiment, the formula for determining the tracing performance may be (tracing coverage × 1.05) - (tracing overflow rate/3) × 100.

Therefore, the tracing score is determined based on the tracing coverage rate and the tracing overflow rate, and the accuracy of similarity judgment is improved.

In an embodiment of the present application, the method further includes: and displaying the simplified characters corresponding to the characters to be traced on the user interface.

Specifically, the user interface of the user terminal may include a simplified text corresponding to the text to be traced.

In an embodiment, the simplified text may be displayed over a canvas area.

In another embodiment, the simplified text may be displayed in a floating window of the user interface, and the display manner and the position of the simplified text are not specifically limited in the embodiment of the present application.

Therefore, the embodiment of the application displays the simplified characters corresponding to the characters to be traced on the user interface, so that the user can conveniently know the specific meanings of the characters to be traced, and the user can learn the characters to be traced more conveniently.

In an embodiment of the present application, before receiving a tracing result of a user drawing a text to be traced in a canvas area, the method further includes: detecting the click position of a user on a user interface; when the click position is located in the canvas area, a drawing operation of a user is received.

Specifically, before step 120 in the embodiment of fig. 1, the method may further include: a click position of a touch click of a user on a user interface with a touch object (e.g., a finger or a mouse) is detected. When the clicking position of the user is located in the canvas area, executing the tracing operation of the user on characters to be traced; otherwise, the user cannot copy the character to be copied.

In one embodiment, a coordinate system may be established on the user interface. The processor may determine whether the current click operation is located in the canvas area by determining coordinates of a click position where the user clicks with the touch object. It should be noted that, in order to determine whether the click position is located in the canvas area, the area coordinates of the canvas area may be stored in advance in the processor of the user terminal.

Therefore, the click position of the user is judged in advance, so that the drawing area of the user is located in the drawing area, and guarantee is provided for subsequent evaluation of the tracing performance.

In an embodiment of the application, the characters to be traced are characters of any one of oracle characters, golden characters and seal characters.
