Design and Implementation of an Arduino-Based Wearable Assistive System for Obstacle Detection in Blind Navigation

Arduino-based wearable assistive system for obstacle detection for blind navigation is an innovative wearable technology designed to improve mobility and safety for the visually impaired. Utilizing an Arduino Uno, the system integrates ultrasonic sensors, a buzzer, and vibration motors, all embedded seamlessly into a comfortable hat. The ultrasonic sensors continuously scan the environment for obstacles, calculating distance with precision. When an obstacle is detected within a predefined range, the system triggers tactile feedback through a gentle vibration and an optional audible alert via a buzzer. This dual-sensory warning system allows users to navigate their surroundings with enhanced awareness, promoting greater independence and confidence in unfamiliar environments. The Arduino-based wearable assistive system for obstacle detection in blind navigation is a practical, cost-effective solution that provides real-time, hands-free obstacle detection. By offering both vibration and sound alerts, it caters to diverse user needs, making it adaptable for varying levels of sensory perception. The simplicity, affordability, and user-centric design of the system make it a highly effective tool in improving the quality of life for the visually impaired, fostering autonomy and ensuring safety in daily navigation.
