The iFLYTEK AI Blackboard is an intelligent education solution designed to address the challenges of insufficient teaching equity, low efficiency, and uneven resource distribution in traditional classrooms. Aimed at promoting "equity, efficiency, intelligence, and safety" in education, it transforms conventional writing tools into an AI teaching assistant through a closed loop of AI perception, decision-making, and service. This solution resolves pain points such as unclear writing due to window glare, difficulty hearing in back rows, and challenges in understanding abstract concepts. It also reduces teachers’ lesson preparation burden, enabling a shift from passive teaching to human-AI symbiosis, thereby advancing educational equity and quaHardware Innovations: AG anti-glare glass, wide-angle display, and AI image optimization eliminate glare interference. AI sound field equalization optimizes audio coverage. Software Breakthroughs: Voiceprint recognition for classroom activation, dynamic number-shape conversion, and a 3D model dissection engine visualize abstract knowledge. Virtual teaching assistants enable cross-temporal dialogue. Application Innovations: Pioneered "question-chain" teaching assistant for critical thinking group activities. Spark Teacher Assistant, powered by a large model, generates lesson plans in minutes (64% efficiency gain) and establishes a closed loop of "unobtrusive teaching behavior collection → intelligent learning analytics → precise strategy optimization."Health Focus: AG anti-glare + wide-angle display protects eyesight, ensuring clarity for window-side and back-row students. AI sound field equalization eliminates auditory blind spots. Safety Assurance: Fully domestic computing foundation ensures data privacy and system security. Voiceprint recognition enables unobtrusive authentication, preventing information leaks. Usability: Retains teachers’ chalk-writing habits; digitized notes project in real time. "Start class" voice command activates the full workflow instantly. Virtual assistant guides problem-solving step-by-step, lowering technical barriers. Promotes educational equity through fair resource distribution and learning analytics.Formal Beauty: Ultra-thin unibody with floating design integrates seamlessly into modern classrooms. Functional Beauty: Split-screen teaching and dynamic number-shape conversion enable "write-and-project" without interrupting flow. Material Beauty: AG anti-glare glass reduces reflections; matte texture enhances visual comfort. Craft Beauty: Precision lamination achieves bezel-free display; wide-angle technology ensures 178° visibility. Technological Beauty: Virtual assistant recreates historical scenes via holographic effects; 3D dissection engine visualizes geometric structures, transforming abstract knowledge into tangible art.Material Reduction: Digital notes replace chalk, reducing dust pollution and consumables. Extensive cloud-based resources replace paper-based materials, cutting paper use. Energy Optimization: AI image optimization adjusts brightness based on ambient light, saving 30% energy. Domestic low-power chips improve energy efficiency. Sustainable Operations: Modular design supports partial hardware upgrades, extending product lifespan. Cloud storage for class recordings replaces local servers, reducing e-waste. Through lightweight interaction and intelligent power management, it enables green empowerment in educational digitalization.
