The paper presents a method to create a portable,prototype navigation system for the blindthat will allow visually impaired individuals to travel through familiar and unfamiliar environments without the assistance of guides or a stick. The system will allow blind travelers to develop a much better representation of the environment through which they are traveling.The system is equipped with RF modules in order to facilitate indoor navigation capability. The system is programmed to give the directions to the desired destination in the form of speech.The embedded system is also capable of detecting obstacles and providing haptic feedback to the blind. Also an Application is developed on the Android platform to achieve outdoor navigation.
