Abstract

This study aims to improve the lives of visually impaired individuals by developing a wearable device using ultrasonic technology. The system consists of an STM32 ultrasonic sensor and a buzzer that detects obstacles in real-time. The device is securely mounted in the user’s glasses, and the buzzer sounds when an obstacle is detected. This state-of-the-art assistive technology addresses the immediate demands of improved safety and navigation for the blind. This study aims to overcome barriers to daily life caused by scene damage, reducing mobility and freedom. The wearable solution enables the visually impaired to confidently explore their surroundings. The device blends with error-free regular glasses, allowing the user to respond quickly to obstacles. The buzzer notifies the user when an obstacle occurs, providing them with the opportunity to respond quickly. This state-ofthe-art assistive technology can completely change the lives of those with visual flaws, providing additional independence in their daily activities. Innovation plays a crucial role in expanding projects on assistive technology for the visually impaired, providing complete information on wearing solutions. This work aims to create a future of technology that bridges to a freer and fulfilling life for everyone.
