Navigational Assistive Interface for Visually Challenged People

Abstract

This project proposes the implementation of the assistive technology to help the visually challenged/impaired people to navigate on the roads independently, as they need someone to assist them even to walk alone. The information about the existence of obstacles will be given by navigational assistive interfaces which are portable electronic devices. Most of the interfaces that exploit tactile stimulation are destined to the finger tips, palms, and soles of the foot. But the capabilities of tactile foot perception for human navigation is little complex. To overcome this, an audio signal is sent through the earphones to assist the user about the presence of obstacles by using the obstacle detector. A situation like falling down in a particular place, automatically a message is sent to the take carer of the visually impaired person using GSM module. It enhances the independent travel which is useful to reach the destination easier and faster.
