Description

Technical Field

[0001] This invention relates to the field of educational technology, specifically to a multi-terminal collaborative handwriting practice and achievement system based on intelligent synchronous assignments. Background Technology

[0002] In traditional teaching, student homework and extracurricular calligraphy practice are separated. Because the content of classroom homework and extracurricular calligraphy practice is not consistent, teachers need to assign tasks repeatedly, resulting in low efficiency in calligraphy practice. Moreover, classroom homework focuses on completing knowledge points and lacks targeted training on writing standards. Teachers need to manually correct homework, making it difficult to identify writing problems in a timely manner. The evaluation is mainly subjective and lacks quantitative standards, making it impossible to provide precise improvement suggestions. Traditional calligraphy practice only marks errors with "circles in red" and does not form a closed loop of "evaluation-feedback-reinforcement practice". It is difficult to correct bad habits. Students lack targeted guidance in calligraphy practice, resulting in poor results. There is insufficient cooperation between home and school, and parents cannot keep track of their children's writing progress and problems in real time.

[0003] While existing technologies include electronic handwriting practice tools, they cannot seamlessly integrate with paper-based assignments, and the accuracy of assessment feedback is insufficient. For example, current electronic handwriting practice products (such as tablet calligraphy practice books) rely on screen writing, deviating from the real paper-and-pen experience, which can easily lead to distorted writing habits in students. The disconnect between paper assignments and digital tools prevents the digitization and dynamic analysis of handwriting data. Therefore, most systems only focus on the overall aesthetics of the characters, ignoring the standardization of strokes (such as stroke order and direction) and structural accuracy, resulting in a single assessment dimension. Similar smart handwriting practice tools only mark errors and do not generate progressive achievement tasks, failing to force students to strengthen their weak points, resulting in a lack of dynamic closed loop. Furthermore, smart pens rely on online transmission, making offline data easily lost. The lack of data sharing between home and school, and the inability of teachers and parents to coordinate intervention, leads to insufficient scenario adaptation. There is an urgent need for a multi-terminal collaborative handwriting achievement system that combines coded handwriting practice books with smart pens to solve the above pain points. Summary of the Invention

[0004] In view of this, and in response to the problems of separation between homework and handwriting practice, low efficiency of manual correction, lack of feedback mechanism and limitations of technical tools in traditional handwriting teaching, the purpose of this invention is to propose a multi-terminal collaborative handwriting achievement system based on intelligent synchronous homework. Through the collaborative work of a coded homework book, a smart pen, a three-dimensional evaluation algorithm and a closed-loop management process, this system solves the problems of low efficiency, delayed feedback and insufficient home-school collaboration in traditional handwriting teaching.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] To achieve the above objectives, the present invention provides a multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation, comprising the following components:

[0007] The "Practice Calligraphy with Coding" workbook is printed on paper with encrypted coordinate dot matrix codes. Each dot matrix area is uniquely bound to the standard font library, and dynamic tracing ratios are set at different levels.

[0008] Smart pen terminal: It integrates an optical recognition module, a trajectory acquisition module and a communication module, which are used to collect handwriting data including writing coordinates, pen pressure and speed in real time and transmit it to the management backend;

[0009] Three-dimensional dynamic evaluation module: Based on the standardization of strokes, the standardization of character shape, and the accuracy of structure, a three-dimensional dynamic evaluation model is constructed to calculate the total score and dynamically adjust the threshold for achieving the standard according to the grade level;

[0010] The target achievement task generation module is used to automatically generate three types of progressive target achievement tasks—self-practice, guided practice, and supervised practice—when the score is below the threshold, and to trigger home-school collaborative intervention.

[0011] Multi-scenario adaptation module: used to support seamless switching between offline storage, online synchronization and emergency photo submission modes, to synchronize data and facilitate home-school collaboration.

[0012] As a further aspect of the present invention, the dot matrix code points in the calligraphy practice notebook are coordinate dot matrices encrypted by printing on paper pages. Each dot matrix area is uniquely mapped to the standard character library in the background, which is used to accurately locate the writing position.

[0013] As a further aspect of the present invention, the synchronized practice book for handwriting exercises, when setting the dynamic tracing ratio for different grade levels, is divided into "more tracing and less writing" (grade 1), "half tracing and half writing" (grade 2), and "less tracing and more writing" (grade 3), to suit the writing difficulty.

[0014] As a further aspect of the present invention, the synchronized practice book for calligraphy includes:

[0015] The writing demonstration area uses serial numbers and arrows to indicate the stroke order and direction, providing a standard reference;

[0016] The homework and calligraphy practice area is synchronized with the vocabulary list in the textbook, so as to unify the content of classroom assignments and extracurricular calligraphy practice.

[0017] As a further aspect of the present invention, the optical recognition module in the smart pen terminal uses a high-speed camera to capture code dot patterns and locate writing coordinates; the trajectory acquisition module includes a pressure sensor and a gyroscope to record pen pressure, speed, and movement trajectory; and the communication module supports real-time Bluetooth transmission and offline storage.

[0018] As a further aspect of the present invention, the three-dimensional dynamic evaluation model constructed by the three-dimensional dynamic evaluation module calculates the total score by including the following steps:

[0019] Three evaluation dimensions were set: stroke standardization (B), character shape standardization (Z), and structural accuracy (J), and scores were calculated for each evaluation dimension.

[0020] Stroke standardization (B) is an evaluation dimension for deviations in stroke order, direction, and length. The formula for calculating the stroke standardization score is as follows:

[0021]

[0022] Character form standardization (Z) is an evaluation dimension encompassing center of gravity offset, radical proportion, and spacing uniformity. The formula for calculating the character form standardization score is as follows:

[0023]

[0024] Structural accuracy (J) is an evaluation dimension for width-to-height ratio and overall compactness. The formula for calculating structural accuracy is:

[0025]

[0026] Calculate the total score (X) and dynamically adjust the pass threshold according to the grade level. The formula for calculating the total score is as follows:

[0027]

[0028] In the formula, X represents the total score; B represents the stroke standardization score; Z represents the character shape standardization score; and J represents the structural accuracy score.

[0029] As a further aspect of the present invention, when dynamically adjusting the achievement threshold according to grade level, the achievement threshold may be fluctuated up or down by 0% to 10% based on the grade level difficulty coefficient.

[0030] As a further aspect of the present invention, the closed-loop process of the target training task generation module includes:

[0031] Practice independently, and the system will automatically push description reinforcement tasks for words that have not yet met the standards;

[0032] If the student fails to meet the standard during independent practice, a guidance prompt will be triggered on the parent / teacher's end to reinforce stroke guidance.

[0033] If a student fails to meet the standards twice consecutively during the supervision training, the system will lock the task and force home-school collaboration until the score is satisfactory.

[0034] As a further embodiment of the present invention, the target-achieving training task generation module also uses a blank notebook and terminal device display text to complete the target-achieving training.

[0035] As a further aspect of the present invention, the multi-scenario adaptation module includes:

[0036] Offline storage mode: The smart pen stores unsynchronized data, which will be automatically uploaded once the network is restored.

[0037] Emergency photo submission mode supports uploading paper assignments by photo, and uses image recognition technology to extract handwriting and provide points compensation.

[0038] In the online data synchronization mode, teachers and parents can share writing reports, achievement progress, and error heatmaps in real time.

[0039] As a further aspect of the present invention, the multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation also includes:

[0040] The teacher-side automation module generates an error heatmap based on the class's achievement rate and automatically recommends targeted teaching resources.

[0041] The parent-side real-time feedback module receives homework status (incomplete / requires extra practice) and a progress chart of handwriting; it also provides suggestions for home tutoring (such as correcting pen grip posture).

[0042] Points-based incentive system: Students earn points by writing neatly and submitting on time, which can be redeemed for virtual badges or physical rewards.

[0043] As a further aspect of the present invention, the multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation also includes:

[0044] The standard character set is used to convert different new characters in textbooks into standard characters that conform to writing standards and include, but are not limited to, dot matrix information such as strokes, structure and character shape, and to associate them with resources such as standard writing animations;

[0045] The template batch generation module supports teachers in creating custom calligraphy practice content, and the system automatically generates corresponding code sheets and synchronizes them to the students' devices.

[0046] Compared with existing technologies, the multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation proposed in this invention has the following beneficial effects:

[0047] This invention achieves precise positioning of the writing position by using dot-matrix codes in a synchronized handwriting practice notebook, ensuring that each dot-matrix area is uniquely bound to a standard character set. It also features dynamically tiered tracing ratios, allowing for different tracing ratios to suit the writing difficulty of students at different grade levels. The integrated optical recognition, trajectory acquisition, and communication modules in the smart pen terminal can collect handwriting data, including writing coordinates, pen pressure, and speed, in real time and transmit it to the management backend for real-time monitoring and data analysis. Furthermore, it supports Bluetooth real-time transmission and offline storage, ensuring data integrity even in the absence of a network connection. By constructing a system based on stroke standardization… The three-dimensional dynamic evaluation model, which assesses the standardization of character shape and the accuracy of structure, can comprehensively evaluate handwriting quality. It dynamically adjusts the threshold for achieving the standard according to grade level, making the evaluation criteria more adaptable and flexible. It can also automatically generate three progressive achievement tasks based on the scoring results: self-practice, guided practice, and supervised practice, and trigger home-school collaboration to ensure that students can gradually improve their handwriting skills. It supports seamless switching between offline storage, online synchronization, and emergency photo submission modes to ensure data integrity and timeliness. By writing in a standardized manner and submitting assignments on time, students can earn points that can be redeemed for virtual badges or physical rewards, thereby stimulating students' learning enthusiasm.

[0048] This invention achieves a comprehensive improvement and optimization of handwriting instruction through intelligent, data-driven, and multi-terminal collaborative methods, significantly enhancing students' writing skills and teachers' teaching efficiency, while also strengthening home-school cooperation. It has broad application prospects and significant educational value.

[0066] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0067] To address the problems of separation between homework and handwriting practice, low efficiency of manual grading, lack of feedback mechanisms, and limitations of technological tools in traditional handwriting instruction, this invention proposes a multi-terminal collaborative handwriting achievement system based on intelligent synchronous homework. Through the collaborative work of a coded workbook, a smart pen, a three-dimensional evaluation algorithm, and a closed-loop management process, it solves the problems of low efficiency, delayed feedback, and insufficient home-school collaboration in traditional handwriting instruction.

[0068] See Figures 1 to 10 As shown, an embodiment of the present invention provides a multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation, comprising the following components:

[0069] The "Practice Calligraphy with Coding" workbook is printed on paper with encrypted coordinate dot matrix codes. Each dot matrix area is uniquely bound to the standard font library, and dynamic tracing ratios are set at different levels.

[0070] Smart pen terminal: It integrates an optical recognition module, a trajectory acquisition module and a communication module, which are used to collect handwriting data including writing coordinates, pen pressure and speed in real time and transmit it to the management backend;

[0071] Three-dimensional dynamic evaluation module: Based on the standardization of strokes, the standardization of character shape, and the accuracy of structure, a three-dimensional dynamic evaluation model is constructed to calculate the total score and dynamically adjust the threshold for achieving the standard according to the grade level;

[0072] The target achievement task generation module is used to automatically generate three types of progressive target achievement tasks—self-practice, guided practice, and supervised practice—when the score is below the threshold, and to trigger home-school collaborative intervention.

[0073] Multi-scenario adaptation module: used to support seamless switching between offline storage, online synchronization and emergency photo submission modes, to synchronize data and facilitate home-school collaboration.

[0074] This invention integrates classroom assignments with extracurricular calligraphy practice. By combining a synchronized calligraphy practice notebook with a smart pen, students upload their handwriting. The assessment system then provides personalized feedback on non-standard characters and reinforces existing practice in the target practice notebook. Through the upload of handwriting from the synchronized practice notebook and the smart pen, the platform system provides assessment feedback, personalized reinforcement practice in the target practice notebook, automated platform tracking, and ultimately, student calligraphy practice that meets the standards, thus improving their handwriting accuracy. It also reduces the burden of homework and calligraphy practice for students, eliminating the need for teachers to grade assignments through the platform's automated system, while providing real-time feedback on student homework status and data, thus facilitating home-school collaboration.

[0075] In this embodiment, the dot matrix code in the calligraphy practice notebook is a coordinate dot matrix encrypted by printing on the paper page. Each dot matrix area is uniquely mapped to the standard font library in the background, which is used to accurately locate the writing position.

[0076] Among them, the synchronized practice book for calligraphy practice with the code-laying function sets the dynamic tracing ratio according to grade level, with "more tracing and less writing" (grade 1), "half tracing and half writing" (grade 2), and "less tracing and more writing" (grade 3) to suit the writing difficulty.

[0077] The synchronized practice book for calligraphy includes:

[0078] The writing demonstration area uses serial numbers and arrows to indicate the stroke order and direction, providing a standard reference;

[0079] The homework and calligraphy practice area is synchronized with the vocabulary list in the textbook, so as to unify the content of classroom assignments and extracurricular calligraphy practice.

[0080] In this embodiment, as a calligraphy practice homework synchronization system, the coded calligraphy practice homework synchronization book not only arranges the writing ratio according to the characteristics of primary school students at different stages and the calligraphy practice content is consistent with the school textbook content, but also lays coordinate dot matrix codes on the paper of the homework calligraphy practice synchronization book, so as to be able to combine with the smart pen to complete the collection and uploading of relevant writing trajectory data to the system, and complete the evaluation through a three-dimensional evaluation algorithm.

[0081] In terms of the difficulty of calligraphy practice, it is personalized to match children at different stages; in terms of the content, it is synchronized with the school's writing list, so as to integrate classroom assignments and extracurricular calligraphy practice without adding extra burden to calligraphy practice; in terms of feedback, offline assignments are digitized and feedback is provided through online evaluation, so as to make calligraphy practice more efficient.

[0082] Specifically, the coded handwriting practice notebook is a paper-based workbook with specific square-shaped dot patterns printed on its pages. These coded patterns, composed of recognizable square dots, are used in conjunction with a smart pen to accurately locate the writing position. The coded dot matrix information is matched with the page, with each dot matrix area corresponding to unique coordinate information. This allows the smart pen to obtain the current writing position and page writing information by recognizing the dot matrix pattern. As a fusion of classroom assignments and textbook handwriting practice, it conforms to handwriting practice habits without increasing students' homework burden. In terms of content arrangement, it provides appropriate handwriting guidance, conforms to the writing proportions of elementary school students, and enables more efficient handwriting practice. In addition to the above design, the handwriting practice notebook incorporates coded technology, which, combined with the smart pen, completes handwriting collection and analysis, achieving highly efficient handwriting practice.

[0083] In this embodiment, the optical recognition module in the smart pen terminal uses a high-speed camera to capture code dot patterns and locate writing coordinates; the trajectory acquisition module includes a pressure sensor and a gyroscope to record pen pressure, speed, and movement trajectory; and the communication module supports real-time Bluetooth transmission and offline storage.

[0084] The process of uploading handwriting using a smart pen includes the following steps:

[0085] 1) The smart pen collects coded patterns and handwriting data in real time while writing;

[0086] 2) Analyze and process the data and convert it into JSON data;

[0087] 3) Upload the JSON data packet to the platform system through the communication module and receive feedback instructions.

[0088] In this embodiment, when the smart pen uploads handwriting data, it digitizes the offline handwriting data, enabling online interaction and effectively recording and storing writing data for easy review and analysis. As a component of the system, the smart pen terminal uses a layer of tiny, non-obscuring recognition dots printed on ordinary paper to identify relevant positional information. Simultaneously, a high-speed camera at the front of the smart pen continuously captures the pen tip's movement trajectory. An integrated pressure sensor and trajectory acquisition module capture real-time writing coordinates, pen pressure, and speed data on the marking paper. The pressure sensor transmits the pressure data back to the data processor, which then transmits the information to the platform system via Bluetooth or a data cable, completing the online and offline data interaction.

[0089] In this embodiment, the Puma calligraphy practice notebook serves as the data collection medium. Data is uploaded via a smart pen and evaluated by the platform system. This evaluation is based on a system evaluation algorithm model. The three-dimensional dynamic evaluation module constructs a three-dimensional dynamic evaluation model based on strokes, structure, and character shape as the algorithm model. After collecting relevant writing trajectories with the smart pen, the three-dimensional dynamic evaluation model evaluates the writing, making the evaluation more objective. After receiving feedback, calligraphy improvement becomes more precise and efficient. For characters that do not meet the standards, personalized additional practice is provided through the Puma standard practice notebook to achieve a closed loop. This step still uses a combination of online and offline methods. When the online system analyzes the writing score as below the threshold, the system automatically locks the substandard characters and generates progressive standard practice tasks, including three modes: "self-practice," "guided practice," and "supervised practice," forming a "feedback-additional practice-standard achievement" closed loop.

[0090] The system evaluation and feedback mainly includes the following modules:

[0091] Data receiving module: Receives handwriting data uploaded by the smart pen and verifies data integrity;

[0092] Assessment and Analysis Module: Based on a pre-set library of standard characters, it evaluates handwriting quality through the following dimensions:

[0093] ① Stroke B Standardization: Compare with standard stroke shapes to identify the number of strokes, stroke order, stroke length, and direction;

[0094] ② Z-shape standardization: Analyze the font's center of gravity, proportions, and spacing;

[0095] ③Structural accuracy: The overall width and height ratio of the writing is appropriate.

[0096] The three-dimensional dynamic evaluation model constructed by the three-dimensional dynamic evaluation module calculates the total score by including the following steps:

[0097] Three evaluation dimensions were set: stroke standardization (B), character shape standardization (Z), and structural accuracy (J), and scores were calculated for each evaluation dimension.

[0098] Stroke standardization (B) is an evaluation dimension for deviations in stroke order, direction, and length. The formula for calculating the stroke standardization score is as follows:

[0099]

[0100] Character form standardization (Z) is an evaluation dimension encompassing center of gravity offset, radical proportion, and spacing uniformity. The formula for calculating the character form standardization score is as follows:

[0101]

[0102] Structural accuracy (J) is an evaluation dimension for width-to-height ratio and overall compactness. The formula for calculating structural accuracy is:

[0103]

[0104] Calculate the total score (X) and dynamically adjust the pass threshold according to the grade level. The formula for calculating the total score is as follows:

[0105]

[0106] In the formula, X represents the total score; B represents the stroke standardization score; Z represents the character shape standardization score; and J represents the structural accuracy score.

[0107] When dynamically adjusting the threshold for achieving the target based on grade level, the threshold may fluctuate by 0% to 10% depending on the grade level's difficulty coefficient.

[0108] After students practice using the smart pen on the accompanying synchronized notebook or standardized practice paper, the smart pen collects and stores their handwriting or transmits it to the system in real time via Bluetooth. The system compares and analyzes the written characters against the standard characters in three dimensions, recording any writing problems such as stroke order, writing direction, character shape, and structure in the writing error sets on the student / parent and teacher's ends. Simultaneously, each character receives a total score through three-dimensional evaluation, with a set passing threshold. A score above or equal to the threshold is considered passing, while a score below the threshold is considered failing. The passing formula is as follows: the total score is S, the individual character score is X, and the average score for all characters is calculated as follows: S = (X1 + X2 + X3 + ... + Xn) / N. A total score above the threshold Y indicates passing. Furthermore, based on the difficulty level of the Chinese characters for different grade levels, the passing threshold is adjusted upwards or downwards by 0% to 10%, i.e., Y * (1% to 10%), to match the difficulty of the characters, providing opportunities for further practice and dynamically adjusting the passing threshold.

[0109] In this embodiment, the closed-loop process of the target-achieving training task generation module includes:

[0110] Practice independently, and the system will automatically push description reinforcement tasks for words that have not yet met the standards;

[0111] If the student fails to meet the standard during independent practice, a guidance prompt will be triggered on the parent / teacher's end to reinforce stroke guidance.

[0112] If a student fails to meet the standards twice consecutively during the supervision training, the system will lock the task and force home-school collaboration until the score is satisfactory.

[0113] In this embodiment, the target practice task generation module also uses a blank notebook and terminal device display text to complete the target practice.

[0114] In this embodiment, the "Standardized Practice Notebook" is a notebook associated with the scoring results of the synchronized practice notebook. If all the characters written in the synchronized notebook have achieved the required score, there is no need to use the Standardized Practice Notebook for further practice (except for students' voluntary practice). If any characters are not up to standard, the system will automatically push the Standardized Practice Notebook to the student / parent or teacher, requiring the student to complete the corresponding characters through the Standardized Practice Notebook. The content and description ratio of the Standardized Practice Notebook are consistent with the synchronized notebook, and the practice content is formatted three times: the first time for independent practice, the second time for guided practice, and the third time for supervised practice. Independent practice involves the student completing the practice independently after receiving the information. Guided practice is for students who have not yet achieved the required score in the first independent practice, and it is recommended that teachers or parents participate in the guidance. Supervised practice is for students who have not achieved the required score in the first and second practices, and it is recommended that teachers or parents participate in this step as well.

[0115] Traditional calligraphy practice in schools and extracurricular settings typically only provides an overall evaluation of handwriting, often simply circling poorly written characters. While similar intelligent calligraphy practice systems can identify poorly written characters, they lack a closed-loop system for follow-up and improvement. The Puma Standardized Practice Book, with its personalized supplementary practice, provides overall handwriting evaluation, feedback on writing issues, and continued practice for those who haven't mastered the task until they reach the required standard. Based on the Ebbinghaus forgetting curve, it addresses writing problems promptly, ensuring each character meets the standard, leading to better mastery of standardized handwriting.

[0116] In some embodiments, the multi-scenario adaptation module includes:

[0117] Offline storage mode: The smart pen stores unsynchronized data, which will be automatically uploaded once the network is restored.

[0118] Emergency photo submission mode supports uploading paper assignments by photo, and uses image recognition technology to extract handwriting and provide points compensation.

[0119] In the online data synchronization mode, teachers and parents can share writing reports, achievement progress, and error heatmaps in real time.

[0120] In this embodiment, a multi-terminal collaborative handwriting practice system based on intelligent synchronous assignments automates all actions, including assignment publishing, target practice task push, assignment reminders, and writing report push. This reduces the burden on teachers, increases efficiency, and better facilitates home-school collaboration. The multi-terminal collaborative handwriting practice system provided by this invention achieves digital integration of student assignments and handwriting practice, automated assessment, and personalized feedback through the collaborative work of a synchronized handwriting practice notebook, intelligent pen handwriting upload, platform system, and synchronized handwriting practice notebook. This improves the efficiency of standardized handwriting and reduces the teaching burden.

[0121] This invention discloses a multi-terminal collaborative handwriting practice and achievement system based on intelligent synchronous operation. Combined with intelligent pen handwriting practice, it completes the collection and analysis of writing data without altering normal paper-and-pen conditions. The system then automates a series of statistical analyses, evaluations, and feedback processes through a platform system, thus achieving platform system automation.

[0122] 1) Automatic statistics and recording: Real-time recording of students' homework completion status (such as homework submission time, pass rate, and writing standardization score) and progress of standard practice exercises (such as number of practice sessions and trajectory data); Based on preset scoring rules (such as three dimensions of strokes, character shape, and structure), a student's writing progress curve is generated to intuitively display the trend of changes in writing ability.

[0123] 2) Automatic ranking and points: Generate class / grade rankings based on student homework quality, completion efficiency of standard practice books, and progress, supporting dynamic sorting from multiple dimensions (such as standard handwriting compliance rate and progress speed); establish a points system where students earn points through standardized handwriting, timely completion of homework, and participation in standard practice; set phased reward goals (such as virtual badges for achieving the standard for 7 consecutive days) to motivate students to continue practicing.

[0124] 3) Home-school collaboration: Automatically pushes a class-wide handwriting quality report (such as the top 5 most frequently misspelled Chinese characters and common problems) to the teacher's end to help the teacher adjust the teaching focus; provides real-time feedback to parents on the status of students' homework (such as incomplete or requiring extra practice) and handwriting progress, and provides suggestions for home tutoring (such as guidance on pen grip posture for specific Chinese characters).

[0125] 4) Intelligent Path Planning Module: Pushes adaptive learning resources (such as writing demonstration videos) to match students' current ability level. Automatically detects the quality of completed practice exercises; if the quality is not met twice consecutively (including one simultaneous writing practice exercise), an early warning mechanism is triggered, prompting teachers or parents to intervene and provide guidance.

[0126] The platform system automates homework assignments without altering teachers' previous practice of verbally distributing them; it also enables automatic statistical analysis of homework, facilitating precise teaching and the implementation of reward and punishment strategies. Furthermore, the collaborative information exchange between home and school alleviates conflicts and provides better learning and practice guidance, helping children efficiently improve their handwriting.

[0127] The multi-terminal collaborative calligraphy practice system based on intelligent synchronous operation also includes:

[0128] The teacher-side automation module generates an error heatmap based on the class's achievement rate and automatically recommends targeted teaching resources.

[0129] The parent-side real-time feedback module receives homework status (incomplete / requires extra practice) and a progress chart of handwriting; it also provides suggestions for home tutoring (such as correcting pen grip posture).

[0130] Points-based incentive system: Students earn points by writing neatly and submitting on time, which can be redeemed for virtual badges or physical rewards.

[0131] In this embodiment, the multi-terminal collaborative handwriting practice system based on intelligent synchronous operation further includes:

[0132] The standard character set is used to convert different new characters in textbooks into standard characters that conform to writing standards and include, but are not limited to, dot matrix information such as strokes, structure and character shape, and to associate them with resources such as standard writing animations;

[0133] The template batch generation module supports teachers in creating custom calligraphy practice content, and the system automatically generates corresponding code sheets and synchronizes them to the students' devices.

[0134] This invention achieves precise positioning of the writing position by using dot-matrix codes in a synchronized handwriting practice notebook, ensuring that each dot-matrix area is uniquely bound to a standard character set. It also features dynamically tiered tracing ratios, allowing for different tracing ratios to suit the writing difficulty of students at different grade levels. The integrated optical recognition, trajectory acquisition, and communication modules in the smart pen terminal can collect handwriting data, including writing coordinates, pen pressure, and speed, in real time and transmit it to the management backend for real-time monitoring and data analysis. Furthermore, it supports Bluetooth real-time transmission and offline storage, ensuring data integrity even in the absence of a network connection. By constructing a system based on stroke standardization… The three-dimensional dynamic evaluation model, which assesses the standardization of character shape and the accuracy of structure, can comprehensively evaluate handwriting quality. It dynamically adjusts the threshold for achieving the standard according to grade level, making the evaluation criteria more adaptable and flexible. It can also automatically generate three progressive achievement tasks based on the scoring results: self-practice, guided practice, and supervised practice, and trigger home-school collaboration to ensure that students can gradually improve their handwriting skills. It supports seamless switching between offline storage, online synchronization, and emergency photo submission modes to ensure data integrity and timeliness. By writing in a standardized manner and submitting assignments on time, students can earn points that can be redeemed for virtual badges or physical rewards, thereby stimulating students' learning enthusiasm.

[0135] The multi-terminal collaborative handwriting practice system based on intelligent synchronous assignments of the present invention can combine classroom assignments and extracurricular handwriting practice, and the specific implementation steps of the synchronous handwriting practice system are as follows:

[0136] 1. Based on primary school students' handwriting practice habits and knowledge structure, we have compiled handwriting practice books that are easy for primary school students to understand, and the content is fully matched with the school's writing list, so as to combine Chinese character explanation and handwriting practice;

[0137] 2. Import the designed calligraphy practice notebook into the dot matrix digital layout system, and then enter the Chinese characters into the information entry system to ensure that each cell in the notebook is uniquely matched. Refer to the specific style guide. Figures 2 to 4 As shown;

[0138] 3. Student information entry, related methods include but are not limited to the following methods:

[0139] 3.1 Student parents register on their own, and join the corresponding school and class through the class code provided by the system;

[0140] 3.2 Batch import via class list, including information such as student name, student number, gender, and class

[0141] 4. After the student information is entered into the system, the smart pen is connected to the corresponding account, the writing process refers to Figures 2 to 4 as shown, after writing, as Figure 8 and Figure 9 as shown, after the writing data is collected by the smart pen, it is transmitted to the student / parent end or the teacher end via Bluetooth;

[0142] 5. The data is transmitted to the system, and the system invokes Figure 1 the evaluation algorithm in it to evaluate the writing and feed back the existing problems in writing and the scoring result.

[0143] For example, as Figure 5 shown, when the student writes the Chinese character "Mei" into the system, the system will automatically invoke the algorithm to evaluate the written character, conduct evaluation according to three dimensions, and feed back the final scoring result.

[0144] In some embodiments, the multi-terminal collaborative calligraphy practice compliance system based on smart synchronized assignments of the present invention converts traditional offline calligraphy practice into online digitalization, realizes real-time writing, real-time evaluation and feedback, and judges the compliance and non-compliance conditions according to the scoring result, referring to Figure 6 and Figure 7 the compliance practice task generation interface, and the personalized additional practice on the coded compliance practice notebook is completed through the smart pen, the specific implementation is as follows:

[0145] 1. Student Xiao Ming completes the calligraphy practice assignment "Ye, Hu, Jiao, Fu" on the synchronized calligraphy practice notebook via the smart pen, transmits the writing data to the system via Bluetooth through the wireless transmission device at school, and the evaluation system scores it, as shown in reference Table 1:

[0146] Table 1 Evaluation and Feedback Result Table of the Synchronized Calligraphy Practice Notebook for Assignments

[0147]

[0148] Wherein, the two characters "Ye" and "Fu" have scores higher than the threshold of 65 points, which are completed in compliance, and the total scores of the two characters "Hu" and "Jiao" are 63 points and 59 points respectively, which are lower than the threshold of 65 points, and a compliance practice task is automatically generated.

[0149] 2. The proficiency practice task needs to be completed in conjunction with the code-printed proficiency practice workbook to fulfill the personalized additional practice task. If the "Hu Jiao" in the above implementation steps does not meet the proficiency standard, the proficiency practice task is pushed, and the student completes the first round of "independent practice" independent additional practice task on the code-printed proficiency practice workbook, as shown in Table 2:

[0150] Table 2 Homework Calligraphy Practice Proficiency - Independent Practice Evaluation Feedback Result Table

[0151]

[0152] Wherein, the written character "Hu" is scored 73 points and meets the proficiency standard, while the written character "Jiao" is scored 61 points, which is lower than the threshold of 65 points, and the proficiency practice - guided practice task is generated again.

[0153] 3. Since the written character "Jiao" has not yet reached the proficiency standard, the student needs to complete the second round of "guided practice" on the code-printed proficiency practice workbook, and the system sends a short message to remind parents or teachers to intervene in guiding the additional practice, as shown in Table 3:

[0154] Table 3 Homework Calligraphy Practice Proficiency - Guided Practice Evaluation Feedback Result Table

[0155]

[0156] Wherein, the written character "Jiao" is scored 61 points, which is lower than the threshold of 65 points, and finally the proficiency practice - supervision practice task is generated.

[0157] 4. The system reminds parents or teachers to intervene in supervising the additional practice, and the student completes the third round of "supervision practice" on the supervision practice page of the code-printed proficiency practice workbook, as shown in Table 4:

[0158] Table 5 Homework Calligraphy Practice Proficiency - Supervision Practice Evaluation Feedback Result Table

[0159]

[0160] Wherein, the written character "Jiao" is scored 79 points, which is higher than the threshold of 65 points, and the student completes the homework.

[0161] In this embodiment, the code-printed proficiency practice personalized additional practice task focuses on solving the problems of poor supervision and follow-up of traditional calligraphy practice, and the lack of a calligraphy practice closed loop in similar intelligent calligraphy practice, fundamentally and efficiently solving the problem that well-written characters do not need repeated practice while poorly-written characters are practiced efficiently, so as to quickly achieve the goal of standardized, accurate and rapid improvement.

[0162] In some embodiments, the core goal of the multi-terminal collaborative calligraphy practice proficiency system based on intelligent synchronous homework of the present invention is to reduce the work of teachers in assigning and correcting homework, reduce the burden and increase efficiency for teaching; reduce the homework burden of children and the pressure of parents in supervising their children, and help to practice calligraphy efficiently, as Figure 10 shown, the platform system automatically follows up the specific implementation steps:

[0163] 1. Automatic triggering of homework assignments: Teachers give oral explanations in class, and the system automatically triggers the assignment assignment once a small percentage of students submit their work.

[0164] 2. Student writing process data is automatically transmitted, analyzed, and statistically processed, and relevant writing feedback is automatically delivered to the student / parent and teacher terminals;

[0165] 3. If a student's handwriting does not meet the standard, a practice task to meet the standard will be automatically pushed to them. Once the handwriting meets the standard, the homework task will be completed and a handwriting report will be automatically generated.

[0166] 4. If a student fails to achieve the passing score in two consecutive writing assessments (including writing in the homework / writing practice book), the system will automatically remind the teacher and parents to intervene and provide guidance. If a student fails to achieve the passing score in three consecutive writing assessments (including writing in the homework / writing practice book), the system will also automatically push relevant explanation videos.

[0167] 5. After the daily homework assignments are completed, students / parents will automatically receive a writing report, which includes writing problems and suggestions; teachers will automatically receive a class writing report, which includes the pass rate, a heat map of misspelled words, and a detailed overview of the class's writing.

[0168] In summary, this invention, through intelligent, data-driven, and multi-terminal collaborative methods, has comprehensively improved and optimized handwriting instruction, significantly enhanced students' writing skills and teachers' teaching efficiency, and strengthened home-school cooperation. It has broad application prospects and significant educational value.
