At the World Artificial Intelligence Conference (WAIC) 2026 in Shanghai, Chinese technology company iFLYTEK unveiled its latest AI Smart Blackboard -- an AI-powered classroom system that converts teacher handwriting into digital graphs, 3D geometry models, and interactive lesson content in real time. A video of the demonstration went viral on social media, showing a teacher drawing rough shapes on a physical blackboard while the AI system simultaneously rendered polished 3D models, mathematical graphs, and annotated diagrams on a connected digital display. iFLYTEK states the broader AI Blackboard product line is already deployed at meaningful scale across Chinese schools. The system is designed to assist teachers rather than replace them -- teachers can continue using traditional blackboard methods while the AI augments their content with interactive visualizations. The WAIC conference is one of China's premier AI events, showcasing domestic AI capabilities and commercial applications.
