Abstract

With the global innovation of educational concepts, edutainment has become the core paradigm of educational tool innovation. This study proposes and implements an embedded Tic-Tac-Toe human-computer gaming device, which can automatically identify the positions of the chessboard and pieces, support real-time human-computer game interaction, and complete misoperation detection and correction. With the STM32F103VET6 microcontroller as the main control unit, the device adopts a V831 camera module matched with the improved Canny algorithm to realize high-precision identification of the chessboard and pieces. Drawing on the structural design of 3D printers, it is equipped with an XYZ three-axis precision motion platform driven by closed-loop stepper motors, and places chess pieces via a pneumatic suction nozzle. On the software side, an OLED interactive interface is developed, and a double verification mechanism and built-in referee system are introduced to realize misoperation detection and real-time human-computer game functions. The device finally realizes complex multimodal interaction on a low-computing-power embedded platform, with a repeat positioning accuracy of ±0.15 mm for piece placement and a single-step operation cycle controlled within 3.5 s. It has good stability, and provides a feasible technical reference for the development of low-cost intelligent educational equipment.
