Abstract

People with severe motor disabilities often face significant challenges in using traditional wheelchairs due to limited or no voluntary movement in their hands or arms. This lack of independent mobility greatly impacts their ability to perform daily tasks, reduces their autonomy, and affects their overall quality of life. To address this critical issue, the present project proposes the development of a smart wheelchair system operated through head-tilt control. By detecting the angle and direction of the user's head movements, the system enables intuitive, hands-free navigation, allowing users to control both direction and speed with ease.To ensure safety, the wheelchair is equipped with distance sensors that detect nearby obstacles and automatically prevent collisions. Additionally, a gesture-based on/off feature has been implemented to avoid unintended activations, enhancing both reliability and user confidence. Initial testing has shown that the system responds accurately to user commands, navigates effectively around obstacles, and provides a practical, low-cost solution to improve mobility. This innovation holds great promise for empowering individuals with severe physical impairments, enabling them to lead more independent and fulfilling lives.
