China Unveils AI School Whiteboard That Generates 3D Models from Teacher's Handwriting

At a technology exhibition in Shanghai, Chinese company iFlytek showcased an innovative AI-powered interactive whiteboard designed to transform classroom education. Dubbed 'Tongchuang,' the device recognizes handwritten text and automatically generates three-dimensional graphic models, aiming to replace traditional chalkboards and markers.

The technology promises to streamline the teaching process significantly. When a teacher writes a mathematical equation, the system instantly produces a corresponding graph. Similarly, if a flat figure is drawn on the screen, the built-in algorithm constructs a precise 3D model, which can be rotated directly on the display.

The system's architecture relies on a sophisticated suite of software tools. A module captures pen strokes, recognizes symbols or figures, identifies the subject matter, and then engages either a mathematical engine or a geometric constructor. The final images are generated by verified code, minimizing the risk of errors in formulas or designs. According to iFlytek, similar systems are already being implemented in 33 regions across China, reaching over 1,400 districts, and its voice assistant, Spark Teacher Assistant, is used by approximately one million teachers.

A key differentiator of the Tongchuang board is its automation, eliminating the need for teachers to manually switch between applications or search for 3D objects in libraries. However, industry experts are flagging potential concerns regarding data privacy, as the board is equipped with cameras and lesson recording capabilities. Furthermore, the actual effectiveness of this AI technology compared to conventional projectors requires additional investigation.
