Abstract
The smart walking stick for people with visual impairments is shown in this work and is based on ultrasonic sensors, water sensors, Arduino, and voice processors. The World Health Organization estimates that there are about 37 million blind persons in the world. Individuals with visual impairments frequently require outside help, which may come in the form of trained dogs, people, or specialized technological gadgets that act as decision-support systems. We were thus inspired to create a clever white cane to get around these restrictions. We were able to achieve this by adding ultrasonic sensors to the cane in certain locations that detect items on the left, right, and front sides and reflect the discovered objects to the user under voice processor control. We put forth a low-cost, lightweight device that uses sensors and an Arduino to interpret signals and warn the blind person of any obstacles, bodies of water, or gloomy areas. Thealarm system then warns the user to take immediate action. The system is made up of obstacle and water detection sensors for signal reception, processing, and transmission. The system was created, developed in C language, and validated by a person who is visually challenged. The sensor can detect up to 100cm.
