Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of digital media art teaching equipment, and particularly relates to a color optical teaching demonstration device based on wireless synchronization. BACKGROUND

[0002] As a frontier discipline combining visual art and information technology, digital media art has long been facing the core challenge of converting from physical perception to digital expression in color teaching. Traditional art education relies on physical media such as pigments and canvases, and students understand color relationships by mixing pigments by hand. This process is direct, perceptual and consistent with cognitive laws. However, in the digital creation environment, color operations completely rely on numerical sliders and color wheels in software. This abstract interaction mode breaks the artist's physical intuition of color, making it difficult for students to establish a deep understanding of color models such as RGB / CMYK. Existing teaching methods mostly use software demonstrations combined with theoretical explanations, which can demonstrate color principles but lack physical training sessions that allow students to participate synchronously through touch and vision. As a result, color theory often stays at the abstract concept level and cannot be effectively translated into conscious application in creative practice.

[0003] The current art teaching equipment on the market has obvious limitations in solving this problem. One type is purely digital tools, such as advanced digital screens and color management software, which can accurately display colors but rely entirely on interface operations, providing no physical feedback and deepening the gap between operation and perception. Another type is traditional color teaching instruments, such as mechanical rotating color wheels or optical color mixing demonstration instruments, which can demonstrate color mixing phenomena in a physical way but are single-function and rigid in interaction, generally lacking real-time comparison, quantitative analysis, and real-time interaction capabilities between teachers and students. More importantly, most existing devices operate in isolation and cannot project the teacher's real-time color adjustment process to multiple student terminals, making it difficult to support efficient group teaching and unified evaluation. Therefore, there is an urgent need for a professional teaching device that can bridge physical operation and digital color space, support real-time interaction between teachers and students, and have a reliable and intuitive structure to fill the gap in specialized hardware for digital media art color teaching.

This process converts abstract RGB / CMYK values into visual and tactile mechanical and optical phenomena. In the real-time wireless synchronization and manual comparison interaction between teachers and students, the concept of color mixing, hue and saturation is deeply realized and the skill training is completed.
