Abstract

This project presents a Smart Navigation System developed to assist visually impaired individuals in safe and independent travel. The system utilizes a Raspberry Pi-based embedded platform integrated with GPS for real-time location tracking and OpenStreetMap for route navigation. Users can select predefined destinations through tactile push buttons, after which the system delivers voice-based navigation instructions to guide movement. To ensure continuous functionality, the system operates using available GPS data along with stored positional information during signal interruptions. An ultrasonic sensor is incorporated to detect nearby obstacles and provide immediate audio warnings to enhance user safety. The system is designed to be compact, cost-effective, and easy to operate, making it suitable for practical assistive applications. By combining navigation assistance with real-time obstacle detection, the project demonstrates an effective technology-driven mobility solution for visually impaired users.
