This work focuses on developing a head movement-based cursor control with human–computer interaction that serves as an assistive device for people with physical disabilities to efficiently operate personal computers or laptops. The proposed system uses a microcontroller and a gyroscope to detect head movements and translate them into cursor actions, thereby eliminating the need for conventional input devices. The core functionality relies on a gyroscope to maximize performance and the I2C protocol to ensure an efficient communication between the gyroscope and microcontroller to have a real-time response. The results show that the proposed system achieves higher performance and reliability, making it an effective hands-free solution for controlling the cursor on a computer monitor. The system enhances user independence and smoothly integrates into their daily workflow.
