The video shows Tongchuang's interactive school board, which at the beginning of November was already introduced to several thousand schools in China, and apparently, by September 2027 it will be mandatory (perhaps analogues from other manufacturers) for all schools and universities in China. The board can recognize handwriting and turn drawings or equations into rotating 3D models, graphs and images with captions right during the lesson. Unveiled this summer at the World Conference on Artificial Intelligence in Shanghai, the board uses the large language model of Arouse as a teaching assistant, synchronizing a traditional whiteboard with a digital dashboard to enhance learning in real time.
