The sense of sight is central to the way that human beings perceive and interact with their environment. In visually impaired individuals, vision loss presents enormous difficulties in the ability to detect obstacles and measure distance, making daily navigation challenging and dangerous. In an effort to overcome these challenges, we suggest implementing an AI-based object detection, distance measurement, and sound feedback system into a smart blind stick. In contrast to other conventional systems, our system employs a cost-effective and lightweight Node-MCU microcontroller, three ultrasonic sensors, and a small speaker to provide real-time support. The ultrasonic sensors are well positioned to sense nearby objects and accurately measure the distance of the objects. Such information is read by the Node-MCU and converted into real-time voice signals through a speaker, which allows people to sense their environment via sound. Besides, AI aid is used in sophisticated navigation. The system has an easy-to use interface and can be used for both outdoor and indoor environments. It provides increased mobility and independence to the blind users by integrating effective intelligent navigation distance measurement. The outcome is a low-power, reliable, and scalable solution that greatly enhances safety and independence in everyday life.
