This paper presents the design, fabrication, and experimental analysis of a Head Motion Control Based Wheelchair for individuals with severe motor disabilities. The system utilises an MPU-6050 three-axis accelerometer and gyroscope module mounted on the user\'s head to detect intentional head tilts — forward, backward, left, right, and neutral — and translates them into corresponding wheelchair drive commands via an ESP32 microcontroller and L298N motor driver. Experimental results across 300 trials yield an overall gesture recognition accuracy of 97.3%, average system latency of 124 ms, and successful multi-directional navigation in indoor environments. The system outperforms all prior comparable implementations in accuracy, latency, and is the only design to incorporate continuously variable speed control proportional to tilt angle magnitude
