Ultrasonic glasses and stick for blind

Moving around safely is a daily challenge for visually impaired people. Traditional tools like white canes help detect obstacles, but they only work at a short distance and cannot provide complete awareness of the surroundings. Many modern systems use multiple sensors or cameras, but they are often expensive, complex, and difficult to use in everyday life.

This project presents a Smart Navigation System using an Ultrasonic Sensor that is simple, affordable, and effective. The system uses an ultrasonic sensor to detect obstacles by measuring the distance between the user and objects in front of them. A microcontroller processes this data and immediately alerts the user through vibration or sound when an obstacle is nearby.

The main advantage of this system is its simplicity and low cost, making it suitable for regular use. It is lightweight, portable, and does not require complex setup or training. Compared to other advanced systems, it focuses on providing reliable short-range obstacle detection without using expensive components.

This system helps visually impaired users move more safely and confidently by giving them timely warnings. Overall, it offers a practical and user-friendly solution that improves independence and daily mobility.
