IoT based smart glasses system is designed for real-time environmental assistance and navigation for visually impaired people. The system is implemented using an esp32 microcontroller, integrating a camera module and a microphone for accurate scene capture and voice command processing. The camera continuously monitors the environment and converts visual signals into digital data from precise processing. Object, text and obstacles by analyzing the captured images through a cloud based AI platform. The esp32-cam uploads image and voice prompt data to the cloud platform through WiFi. Alerts recording detected objects, read text, and sense descriptions are sent to the user through an audio speaker using text-to-speech technology. The smart assistance system enhances user safety, improves navigation and provides independent living capabilities, making it cost effective and reliable solution for modern visually impaired users.
