Abstract
This project implements a real-time, FPGA-based 2D drawing system that translates the motion of a LED wand into digital visual output. Using an OV7670 camera and a DE0-Nano-SoC FPGA, the system processes image data to track coordinates and render them onto a VGA display. The design emphasizes hardware processing, synchronization, and effective hardware debugging techniques. The results demonstrate a cost-effective alternative for immersive human-computer interaction interface, with future work focusing on advanced camera register configurations to improve environmental stability and detection accuracy.
