Technology company iFlytek showcased its Tongchuang AI Blackboard at the World Artificial Intelligence Conference in Shanghai from July 17 to 20, Xinhua reported.
Teachers write on it with a smart pen as they would on a traditional board, then tap once to clean up their handwriting. A rough sketch of a triangle snaps into a standard shape and flips into a rotatable 3D model.
The system pulls up related teaching materials on its own and records lessons for students to review later.
iFlytek, a strategic partner of this year's conference, says the board is in routine use across 33 provincial-level administrative regions and more than 1,400 districts and counties.
The company says its wider education products reach over 60,000 schools and 160 million teachers and students.
