Vision impairment has become a major issue these days. It is very difficult for vision impaired people to find path without support from others. Generally, they use wooden cane sticks or their pets for having an imperfect idea about the path while they are travelling which mandates the need for a self-driven support. In this paper, the model of Nav-Belt is presented that will help the visually impaired person to move freely and to sense the environment as well as obstacle present in the surroundings. The obstacle is detected by the means of five IR sensors which provide a feedback of the obstacle. The Nav-belt consists of 8051 microcontroller fed with a program to sense input from 5 IR LED’s and provide a feedback to the user. A buzzer is also incorporated to provide an auditory interface in reference with the input provided by IR LED.
