Description

Technical Field

[0001] This invention relates to the field of educational technology, specifically to an innovative teaching program for university art and fine arts based on virtual reality (VR) technology. By constructing an immersive and highly interactive virtual learning and creation ecosystem, it achieves a deep integration of art theory teaching, technique training, and creative practice, enhancing students' artistic perception, creative expression, and the efficiency of the entire teaching process. It enables peer-to-peer evaluation and exchange, as well as student-teacher evaluation and exchange, increasing students' memory and improving their abilities. Students enhance their own understanding while evaluating others, leading to a deeper understanding of the learned knowledge. Specifically, it relates to an interactive teaching method and system for university art and fine arts using virtual reality technology. Background Technology

[0002] Traditional university art education is limited by physical venues, materials, and static teaching resources, resulting in problems such as low fidelity in recreating art scenes, difficulty in concretizing abstract theories, high costs of trial and error in creation, and insufficient real-time interaction between teachers and students / students. While the application of VR technology in art education has begun, it suffers from significant shortcomings: some systems focus solely on teaching management and flow control, lacking core creative interaction and precise assessment functions; some solutions, while involving virtual scenes and basic interaction, suffer from low integration of teaching content and technology, limited AI assessment dimensions, insufficient support for multi-person collaborative creation, poor hardware compatibility, and significant motion sickness. Furthermore, high equipment costs, high technical barriers for teachers, and lack of digital resource copyright protection hinder the large-scale application of VR technology in university art education. Therefore, there is an urgent need to develop an integrated interactive teaching system that balances immersive experience, teaching depth, assessment accuracy, and practical feasibility. Summary of the Invention

[0008] A virtual reality-based interactive teaching method for university art and fine arts includes the following steps: 1. System Setup: Based on the teaching objectives of universities, complete hardware selection and network configuration, develop a cross-system (Android / Windows MR) software platform with a crash rate controlled below 0.5%, and pass joint review by subject matter experts and educational technology experts. The hardware includes a control host and multiple connected sub-units. The host can use a Zigbee / Bluetooth Mesh dual-mode wireless socket gateway, a Zigbee 3.0 wired gateway, a central control screen knob button host, etc. (the AI ​​is continuously upgradable, the AI ​​algorithm provides a scoring structure, and the AI ​​creates, saves, and references scores). The sub-units can use the Poda AI Digital Human All-in-One Machine (supporting sub-unit interaction). The host can control the sub-units, but the sub-units cannot control the host. The host can see the screen on each sub-unit, and teachers can control the focus and switch between individual student pages. The host can also see the pages of all students, enabling peer-to-peer evaluation and communication, as well as peer-to-peer evaluation and communication between students and teachers. This not only increases students' memory and improves their abilities, but also enhances their own level while evaluating others, and deepens their understanding of the knowledge they have learned.

[0009] 2. Content Production: Utilizing 3D modeling, animation, and Python programming technologies, we complete scene replication and modular course development to ensure the accuracy of knowledge points (the error between virtual and real teaching data is ≤5%); 3. Tiered Training: We provide training for teachers on "technical operation + content design" and basic training for students on "equipment use + creative skills," accompanied by illustrated tutorials and video guidance; 4. Teaching Implementation: Follow the process of "pre-class VR preview (≤30 minutes) - in-class virtual and real combination (VR practice + group discussion) - post-class VR review + work optimization", record students' learning trajectory data, and conduct system iteration and optimization every semester.

[0012] As a preferred embodiment of this invention, the deeply interactive teaching content system is modularized into courses covering four major modules: art history appreciation, painting techniques (sketching / color / oil painting), sculpture creation, and design thinking. Each module contains four levels of content: "theoretical explanation - demonstration - simulation practice - creative creation." Interactive design: the art history module supports the "masterpiece deconstruction" function, which can 3D recreate the creative steps; the painting module provides 12 material types to choose from, with a rendering speed of up to 90fps, and supports real-time simulation of brush stroke thickness and color mixing; it incorporates an "error operation warning" mechanism, which provides real-time prompts for improper operations (such as perspective deviation) and provides corrective demonstrations during technique practice.

[0013] As a preferred embodiment of the present invention, the AI ​​intelligent evaluation and feedback system includes: an evaluation algorithm that integrates the StyleGAN3 style transfer network to quantitatively evaluate four dimensions: color transition (ΔE value optimized to 3.2), perspective accuracy (improved to 89.3%), shape complexity (supporting level 7.2 complexity processing), and style fit; a feedback mechanism that automatically generates personalized learning reports and pushes targeted reinforcement exercises; and a teacher-side system that supports remote monitoring of the student's creative process and provides real-time guidance through voice or virtual annotations, reducing feedback time by 73.6%.

[0014] As a preferred embodiment of the present invention, the final collaborative creation and resource sharing system includes: Social functions: supporting up to 6 people to collaborate simultaneously, with real-time visibility of peer operation trajectories, and built-in voice communication and virtual gesture interaction; Display and copyright: building a digital twin exhibition hall (loading speed < 1.2 seconds), supporting 200,000 people to view the exhibition online simultaneously; integrating a robust digital watermarking system with ≥ 95% to protect students' creative copyrights; Resource library: constructing an open art education resource library, integrating classic works and teaching cases from around the world, supporting offline caching (capacity ≥ 10GB), and ensuring teaching continuity during network fluctuations.

[0015] The beneficial effects of this invention are: 1. This invention improves learning efficiency: it visualizes abstract art concepts, increases perspective accuracy by 40.2%, reduces the time for switching between multiple perspectives from 6.8 seconds to 1.2 seconds, and increases students' speed of mastering knowledge points by more than 50%. 2. This invention stimulates creative potential: Unrestricted creative space and a wide selection of materials, combined with natural scene simulation, increase students' creative inspiration rate by 41.2% and the complexity of their works by 60%; 3. Enable personalized teaching: The AI ​​assessment system accurately matches students' weaknesses and provides customized learning paths to meet the improvement needs of students with different backgrounds; 4. Reduce teaching costs: Virtual materials replace physical paints and sculpting materials, reducing resource waste; lightweight resource libraries and multi-mode hardware compatibility lower the threshold for equipment investment in universities. 5. Expanding the boundaries of exchange: Collaborative creation across time and space and global resource sharing break geographical limitations, increasing the exposure of student works by 37 times and promoting inter-school art education cooperation.

[0020] Working Principle: In operation, the forward rotation of the servo motor 2 first drives the translation plate 20 to move rearward. The translation plate 20 then drives the sliding wheel 19 to move rearward within the U-shaped plate 17, causing the X-shaped connecting rod 18 to extend and drive the lifting plate 11 to move upward. The lifting plate 11 then drives the inner equipment mounting box 14, the sealing plate 10, and the outer equipment mounting box 8 to move upward, causing the inner equipment mounting box 14 to move out of the outer casing 1. During this upward movement, the actuating column 21 actuates the spiral groove 28, causing the rotating shaft 27 to drive the rotating plate 23 to rotate. This causes the rotating plate 23 to drive several inner equipment mounting boxes 14 to expand outward via several L-shaped rods 25 (the top of the inner equipment mounting box 14 is slidably connected to the bottom of the sealing plate 10, and a column connects the sealing plate 10 and the lifting plate near the left side). The equipment can then be installed in the outer equipment mounting box. Inside box 8 and inner equipment mounting box 14, the reverse rotation of motor 2 drives translation plate 20 to move forward. Translation plate 20 drives sliding wheel 19 to move forward within U-shaped plate 17, causing X-shaped connecting rod 18 to retract and drive lifting plate 11 to move downward. Lifting plate 11 drives inner equipment mounting box 14, sealing plate 10 and outer equipment mounting box 8 to move downward, causing inner equipment mounting box 14 to move into sub-unit housing 1. During the downward movement, actuating column 21 actuates spiral groove 28, causing rotating shaft 27 to drive rotating plate 23 to rotate. Rotating plate 23 drives several inner equipment mounting boxes 14 to retract outward through several L-shaped rods 25, which can realize the movement of inner equipment mounting boxes 14 out or into sub-unit housing 1, and effectively extend and retract at the same time, so that they can be effectively placed, installed and maintained.

[0021] Example 2 like Figures 1 to 13As shown, a virtual reality-based interactive teaching method for university art and fine arts includes the following steps: 1. System Setup: Based on the teaching objectives of universities, complete hardware selection and network configuration, develop a cross-system (Android / Windows MR) software platform, control the crash rate to below 0.5%, and pass joint review by subject matter experts and educational technology experts; the hardware includes a control host and multiple connected sub-units. The host can adopt a Zigbee / Bluetooth Mesh dual-mode wireless socket gateway, a Zigbee 3.0 wired gateway, a central control screen knob button host, etc. (the AI ​​can be continuously upgraded, the AI ​​algorithm provides a scoring structure, and the AI ​​creates, saves, and references). The sub-units can adopt the Poda AI digital human all-in-one machine (supporting sub-unit interaction). The host can control the sub-units, but the sub-units cannot control the host. The host can see the screen on each sub-unit, and the teacher can control the attention to switch between students and switch to individual student pages. The host can also see the pages of all students, which can realize mutual evaluation and communication between students and between students and teachers. This can not only increase students' memory and improve their abilities, but also enhance their own level while evaluating others, and deepen their understanding of the knowledge they have learned. 2.

Tiered training: Training for teachers on "technical operation + content design" and basic training for students on "equipment use + creative skills", accompanied by illustrated tutorials and video guidance; 4. Teaching Implementation: Follow the process of "pre-class VR preview (≤30 minutes) - in-class virtual and real combination (VR practice + group discussion) - post-class VR review + work optimization", record students' learning trajectory data, and conduct system iteration and optimization every semester.

[0022] (1) VR hardware adaptation platform Core equipment: A lightweight head-mounted display (single-eye resolution ≥2K, refresh rate ≥90Hz, weight ≤300g) is selected, supporting diopter adjustment from -6.00D to +2.00D, compatible with domestic devices (such as Pico Neo3), and the dizziness index is controlled below 0.3; Interactive device: Equipped with a six-degrees-of-freedom (6DoF) positioning system (reducing spatial perspective deviation by 62.8%), high-precision motion capture equipment (tracking accuracy ≤1mm) and a hand controller, supporting more than 10 basic artistic creation actions (grabbing, rotating, brush stroke adjustment, etc.).
