Abstract
Smart shoes for blind individuals are an innovative assistive technology that enhances mobility and safety. These shoes integrate ultrasonic sensors, vibration motors, and microcontrollers to detect obstacles and provide real-time feedback through haptic or auditory alerts. This hands-free system helps visually impaired users navigate unfamiliar environments with greater confidence and independence.
The project aims to bridge the accessibility gap by offering a practical and wearable solution that minimizes the risks associated with traditional mobility aids like canes and guide dogs. By incorporating GPS navigation, terrain detection, and a user-friendly design, smart shoes empower users to move freely and safely in various environments, ensuring a better quality of life.
Introduction
Navigating public and private spaces presents significant challenges for blind individuals. Traditional assistive tools, such as white canes and guide dogs, have limitations in detecting distant objects, terrain variations, or unexpected obstacles.
The Smart Shoes for Blind People project introduces a wearable, sensor-based navigation system that detects obstacles and provides instant feedback through vibration or sound signals. The system is designed to work seamlessly in different environments, from urban streets to indoor spaces, reducing the dependency on external assistance and improving self-reliance.
