Smart Stick For Visually Challenged People

Visually challenged persons face constraints in independent mobility and navigation. Mobility means the possibility of liberally moving, without support of any supplementary person, at home and unfamiliar scenarios. People with visual impairment tackle enormous limitations in terms of mobility. Our project focuses on obstacle detection, and finding location in order to enhance navigation facilities for visually impaired people. A system which guide or assist people with vision loss, ranging from partially sight to totally blind, by means of sound commands is referred as Navigation Assistance for Visually Impaired (NAVI). Many researches are being conducted to build navigation system for blind people. But most of them have limitations with respect to accuracy, usability, coverage which is not easy to overcome with current technology for both indoor, outdoor navigation.
