Design and Implementation of IoT Based Smart Glasses Device for Visually Impaired People

Abstract: Visually impaired people face tremendous challenges in navigating their environment in a safe and independent way. As a response to these challenges, this project provides the Smart Glasses for Visually Impaired People, an assistive device to enhance mobility, safety, and emergency y communication. The system utilizes ultrasonic sensors, ESP32 Wi-Fi module, GPS module, GSM module, vibration motor and LiPo battery to provide real-time obstacle detection, GPS navigation n, and emergency SMS notification n. The ultrasonic sensors detect objects at a distance of up to 1 meter, and the system provides haptic (vibration) and audio feedback to alert the user. During an emergency, the GSM module (A6) sends an SMS alert along with GPS coordinates to a pre-registered contact, allowing remote assistance. The ESP32 module sends real-time location and sensor data to Thing Speak, allowing remote tracking of the user's movement. The data from thingspeak retrieved to the web page dashboard. The system is energy-efficient, low-cost, and portable, suitable for the visually impaired. It offers real-time obstacle detection, IoT-based remote tracking, and emergency response, significant ly improving user safety and mobility. The system was successfully tested and demonstrated high accuracy in obstacle detection and seamless GSM-GPS communication.
