Blind People uses white canes to aid in obstacle detection & avoidance. Guide dogs c an also be of limited aid for finding the way to a remote location . So our goal is to create a portable, simple less costly system that will allow Blind peoples to travel through familiar and unfam iliar env ironments without the aid of guides. Several guidance system has been developed for vision impaired people , but these systems tends to be expensive, also make use of a client server approach . This Navigation system consists of two distinct compo nents: sensing of the immed iate environment for blind people to travel (e.g., obstacles and hazards) and navigating to remote destinations beyond the immediately perceptible environment. The paper described here focused on the development and evaluation of a Navigation system that makes use of GPS (the Global Positioning System), voice and ultrasonic sensor for obstacle detection .
