Description

Technical Field

[0001] The present invention relates to the technical field of Chinese character stroke order learning, and particularly to a Chinese character stroke order learning system combining text and image processing. Background Art

[0002] Chinese characters are the writing system of the Chinese language. It is a logographic script, that is, each Chinese character usually represents a meaning or a word. Chinese characters are composed of one or more strokes, and different strokes have different writing methods. Mastering the stroke order of Chinese characters helps to improve writing fluency and aesthetics. The writing stroke order of Chinese characters follows certain rules. Generally, write the horizontal stroke first and then the vertical stroke, such as the character "十" (ten), write the horizontal stroke first and then the vertical stroke; write the left-falling stroke first and then the right-falling stroke, such as the character "人" (person), write the left-falling stroke first and then the right-falling stroke; from top to bottom, such as the character "三" (three), write the top horizontal stroke first, then the middle horizontal stroke, and finally the bottom horizontal stroke; from left to right, such as the character "汉" (Han), write the three dots on the left first and then the right part; write the outer part first, then the inner part and then seal it, such as the character "国" (country), write the outer frame first, then the "玉" inside, and finally seal it; write the middle part first and then the two sides, such as the character "小" (small), write the vertical hook in the middle first and then the dots on both sides.

[0003] At present, when primary and middle school students learn Chinese characters, they often only focus on the writing stroke order and ignore the pronunciation and meaning of Chinese characters. Such a learning method is likely to lead to one-sided understanding of Chinese characters by students and affect the all-round development of language ability. Chinese characters are not only writing symbols, but also carry rich culture and history. Learning writing alone may cause students to be unable to understand the context and meaning of Chinese characters in actual use. Moreover, in traditional writing learning, writing practice is mostly carried out through exercise books, copybooks, etc., and there is often a lack of interactivity, which makes students prone to boredom. In view of this, it is necessary to explore and research a Chinese character stroke order learning system combining text and image processing. Summary of the Invention

Embodiment III

[0038] Refer to the appendix Figure 1 , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that this application is further described by taking the study of the character "人" as an example. The specific process is as follows: S1: The user selects the character "人" on the touch display screen. S2: The system extracts relevant knowledge such as the stroke order (first the left-falling stroke and then the right-falling stroke), cultural background (representing the image of a person, etc.), pronunciation and meaning (pronounced as "rén", meaning a higher animal that can make tools and use tools for labor) of the character "人" from the database, plays the stroke writing animation of the character "人" on the touch screen through the animation display module, and at the same time the knowledge explanation module provides the relevant pronunciation and interpretation.

[0043] This system not only focuses on the stroke order of Chinese characters, but also through the database and knowledge explanation module, uses various media forms such as text, pictures, audio, and video to explain the meaning, usage, and cultural background of Chinese characters, helping students comprehensively understand the rich culture and history carried by Chinese characters and avoiding one-sided understanding of Chinese characters. For example, when learning the character "龙", in addition to showing the stroke order, it can also explain the pronunciation through audio, show the evolution of the image of the dragon with pictures, and introduce the symbolic meaning of the dragon in Chinese culture with videos; the handwriting board and the image recognition and processing module cooperate to be able to capture the user's writing actions in real time, recognize the written Chinese characters, judge the correctness of the stroke order, and provide feedback in a timely manner, which helps students discover and correct their writing problems in a timely manner. For example, when a student writes the wrong stroke order of the character "木", they can immediately get a prompt and correction; the animation display module vividly demonstrates the writing order and method of Chinese characters through animation, providing visual intuitive teaching, making the learning process more vivid and interesting, and improving students' participation and interest; through the interactive evaluation module, test questions can be generated according to the learning progress of students, and an evaluation report can be generated through answer evaluation and result analysis, enabling students to clearly understand their learning situation and also facilitating teachers or parents to understand the learning progress of students for targeted guidance.

[0044] From the above description, it can be seen that the Chinese character stroke order learning system combining text and image processing of the present invention can not only help students accurately master the writing order of Chinese characters, but also deepen the understanding of Chinese characters, stimulate learning interest, and improve learning effects. Through multimedia teaching, real-time feedback, personalized guidance and other methods, the system can provide a comprehensive, interactive and interesting learning experience, promoting the overall improvement of students' language ability and cultural accomplishment.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.

10. The Chinese character stroke sequence learning system combining text and image processing according to claim 1, characterized in that: The Chinese character stroke sequence learning method combining text and image processing comprises the following steps: S1: The user selects a Chinese character on the touch screen; S2: The system extracts the stroke sequence, cultural background, pronunciation and meaning of the Chinese character from the database, plays the stroke writing animation on the touch screen through the animation display module, and provides the relevant pronunciation and interpretation through the knowledge explanation module; S3: The system generates an animation of the stroke sequence of Chinese characters through the animation generator in the animation display module. The animation player plays the animation to display the writing sequence and method of each stroke. The stroke annotation module displays the name and sequence of each stroke in the animation, and displays it to the user through the touch screen for viewing and learning. S4: The user practices writing Chinese characters in sequence on the handwriting board. The pressure sensor in the handwriting board senses the writing force. The coordinate positioning module captures the stroke position and trajectory. The data transmission interface transmits the captured data to the image recognition and processing module. S5: The image recognition and processing module recognizes the Chinese character image written by the user, extracts the stroke features through the CNN algorithm, and compares it with the standard stroke sequence information in the database to determine the correctness of the stroke sequence. If it is correct, it will record the result and provide positive feedback; if it is incorrect, it will provide guiding feedback, which will be displayed to the user by the user feedback display module; S6: The user generates test questions through the interactive assessment module. After the user answers, the answer assessment submodule compares the user's answer with the standard answer, and the result analysis submodule generates an assessment report based on the result.
