Design and Development of Smart Obstacle Detection Glasses for Visually Impaired Persons

Abstract
This paper presents the design and development of smart obstacle detection glasses intended to assist visually impaired persons in identifying obstacles in front of them. The prototype is built around an Arduino Nano microcontroller and an HC-SR04 ultrasonic sensor mounted on a spectacle frame. The sensor measures the distance to an object by transmitting ultrasonic waves and receiving the reflected echo. The Arduino Nano processes the sensor output and activates an audible alert through a 5 V active buzzer when an obstacle is detected. A green light-emitting diode (LED) is also included as a visual status indicator. The system is powered by a rechargeable 3.7 V lithium-ion battery using a TP4056 charging module and a 5 V boost converter. The developed prototype is reported to be operational and provides a compact, wearable approach to front-side obstacle warning. The design focuses on affordability, portability, and simple operation. The present version uses one ultrasonic sensor and therefore provides front-direction detection only. Multi-direction sensing, voice guidance, and improved outdoor performance are identified as possible future enhancements.
