Wheel Chair System with Eye-Blink Control

Abstract

Mobility options for physically challenged persons have been substantially enhanced by the development of assistive technology. This project showcases an eye-controlled wheelchair technology that aims to empower those with significant mobility disabilities to freely traverse their environment. An Eye Blink Sensor is a part of the system that can regulate the wheelchair's mobility by detecting when the user voluntarily blinks their eyes. To make sure the wheelchair can go safely, it has a Passive Infrared (PIR) sensor that can detect impediments. To warn consumers of impending danger or technical issues, a buzzer is often used. In response to detected eye blinks, the L293D motor driver controls the wheelchair motors. A microprocessor regulates the whole system and facilitates the interaction of its many sensors and actuators. All of these parts work together to make the wheelchair a practical and easy-to-use mobility aid for people with disabilities, raising their level of autonomy and happiness.
