To provide self-determined analysis andfamiliarization to visually impaired people ispopularized an new electronic beneficial appliance called Navcane. This appliance helps people to find obstacle-free paths in both indoor and outdoor framework.Also it aids in the recognition of objects in an indoor setting. The precedence information deduced by the system is impart to the user using tactual and auditory declaration methods.Unlikeextantelectronic travel assistance scheme which are limited to obstacle detection and path finding, the Navcane also helps users by perceive substance in known indoor settings. To test the usefulness of the Navcane, object perception, and rehabilitation for visually impaired people, we assessed it with the help of 120 visually impaired people from a blind school and a home for elderly people. All the assessmentswereaccomplished incontrolledindoorand outdoor test habitat with both a Navcane and a white cane. The preliminary results show thatthewhitecane which gives an alert sound for obstacle detection where asNavcaneisaneffectivedevicefordetecting of obstacles, ascending and descending staircases, navigating wet floors, and object recognition in environments that are known and unknown to the user.It is low cost and as a low power embedded device for obstacle detection and obstacle description.It is andistinctive to appliance visionorganizations.
