Many people with visual impairments can travel
independently, using a wide range of tools and techniques. Blind people are
faced with many problems such as independent and graceful travel.
It is well known that visually impaired people
use their hearing sense to compensate for their reduced eyesight. For instance,
they can recognize sound sources. This project includes a RF transmitter and
receiver section. Receiver Section is on the Blind stick. It has been observed
many times that it is very hard for blind persons to find out their stick. In
this project we will short out this problem by implementing a buzzer on the
blind stick and at the same time we will implement an IR sensor to detect the obstacles.
