Voice Operated Outdoor Navigation System for Blind Persons

The blind persons use several types to detect and avoid obstacles . Guide dogs, white canes is said to have limited aid for finding the way to a location. So the main objective is to create a portable, simple less costly system that will allow them to travel through unfamiliar environments without the aid of guides. Several guidance system has been developed for vision impaired people, but these are tends to be expensive also make the use of a client server approach. By the advancement in modern day ultrasonic sensor, pyroelectric sensor and ARM microcontroller technology, the proposed system aids in navigation via audible output, helping in localizing where they are and to improve their mobility. The audio output gives information on the navigation direction that makes use of GPS and alerts using various sensors. The aim of the project is to help the visually impaired to improve their communication and provides independency to them.
