IoT-Based Navigation Assistance for Visually Impaired People

People view sight as the most significant sense. Thanks to advanced engineering, blind people can communicate with their surroundings more easily. Information is shared quickly and widely, affecting people everywhere and greatly impacting human life. This increases opportunities for comfort and entertainment while reducing hardship and suffering in many areas. Since blind people are a part of our society, technology must have a big influence on their life to enable them to do things that were previously unattainable. The IoT-based navigation aid system presented in this study is intended to improve the freedom of people with visual impairments. The system uses a GPS for real-time location tracking, sensors for obstacle detection, an accelerometer for monitoring user movement and orientation, and an ESP8266 microcontroller for data processing and connectivity. By integrating these components, the device provides audio navigation instructions and immediate alerts through a speaker and buzzer. This ensures that users can navigate unfamiliar environments safely and effectively, receiving real-time feedback and guidance. The system aims to be a cost-effective, reliable, and user-friendly solution for visually impaired individuals, significantly improving their daily navigation experiences.
