Abstract: This paper proposes the development of a walking aid for the visually impaired which can sense the surroundings sideways, front, top and bottom and can provide a guidance for navigation by giving audio messages. The device is capable alerting the caretaker of the user in case of emergency by sending an SMS .The system is designed to be power efficient and low cost to be made affordable to common man. The audio messages delivered can be in any language and user-fed which is independent of the system and it overcomes the problem of language constraint in existing systems. Vibration alerts which are provided in case of closer proximity along with the audio messages help the visually challenged to navigate comfortably and safely.
