Cane Vision: A Cutting-Edge Mobility Assistance System for the Visually Impaired

People with visual impairments face difficulties navigating unfamiliar areas, restricting their daily activities. They often require help from others, guide dogs, or expensive electronic aids to move safely. In this paper, an advanced mobility assistance system for the visually impaired people is created to address the challenges. This affordable, lightweight device uses an image processing concept to alert users about obstacles and puddles through vibrations. It also precisely measures the distance to obstacles, with different vibration patterns indicating varying levels of proximity. This functionality is achieved by combining an ultrasonic sensor, vibration motor, and ESP32 CAM module, all controlled by an ESP32 microcontroller. These components, strategically placed on the cane, provide efficient guidance and improved mobility for visually impaired users.
