AI blackboard turns classroom sketches into 3D models
flash_on In 20 seconds
AI recognizes hand-drawn diagrams and converts them into interactive three-dimensional models instantly.
Already running across 33 Chinese regions in over 1,400 counties, serving 160 million students and teachers.
Helps teachers show geometric shapes from multiple angles, making abstract concepts easier to understand.
Captures classroom content, organizes notes, and generates videos students can review later outside class.
iFLYTEK unveiled the Tongchuang AI Blackboard at a Shanghai tech conference in July 2026. The system recognizes hand-drawn shapes, refines rough sketches into clean geometric figures and transforms them into 3D models teachers can rotate on screen.
Students interact with the models using touch controls to examine shapes from different angles. The blackboard also records lessons, organizes content and creates videos teachers and students can access later. It is designed mainly for mathematics instruction where visualizing geometric structures is challenging.

forum Frequently asked questions
How does the AI know what shape the teacher drew?expand_more
It uses handwriting recognition and visual processing to identify rough sketches, then refines them into standard geometric figures and identifies the underlying mathematical concept.
Can students really rotate the 3D shapes?expand_more
Yes. Students can rotate and examine 3D models from different angles using touch-based controls to explore lines, surfaces and spatial relationships.
What else can the blackboard do besides turn drawings into 3D?expand_more
It recognizes mathematical equations and generates graphs, records entire lessons, organizes classroom notes into summaries, and creates educational videos for later review.
Is this still experimental?expand_more
No. iFLYTEK says the system is actively deployed across all 33 Chinese provincial regions and in regular use across more than 1,400 counties and districts.
