Smart Wearables Using Arduino and Sensors for Visually Impaired People: A Third-Eye

— Smart and wearable devices for visually impaired individuals have advanced significantly, but often face limitations such as limited functionality, high cost, and usability issues. Despite numerous studies and available solutions, providing comprehensive and accessible support remains challenging. This study identifies these gaps through various literature reviews and market analyses, proposing an innovative approach by integrating ultrasonic sensors with the Arduino Pro Mini board to create a 'third eye for the blind.' This device uses ultrasonic waves to detect obstacles and alerts users with buzzer sounds or vibrations, enabling confident and swift navigation. Leveraging advancements in computer science, electrical engineering, and medicine, this solution addresses the limitations of traditional aids like the white cane. According to WHO, 39 million people globally are visually impaired, facing significant daily challenges. Existing technologies offer alternatives, but the given solution uniquely enhances mobility by allowing users to locate and recognize objects in their vicinity, providing alerts through vibrations or beeps when objects are detected. This approach offers a practical, cost-effective, and user-friendly alternative, significantly improving the quality of life for visually impaired individuals by enhancing their ability to travel safely and independently.
