Live Obstacle Detection Audio System for Visually Impaired People

Abstract

Object detection is the complex task for the visually impaired people when they are on move. This paper proposes smartphone’s capability more useful for visually impaired people to overcome day to day problems with live navigation. Depth sensing camera is used to differentiate foreground objects from background objects which is used to place real world objects in different layers. As soon as the user moves to the particular layer the fore coming objects are detected and notified to the user by audio instructions. Information from the internet can be collected using the mobility services. The headphone with mic is used by the system for receiving user’s voice input. Emergency tasks like sending SMS and location are sent to the subject’s guardian while the subject is in danger with the help of player. This concept allows visually impaired people to walk both indoors and outdoors independently. Experimental results obtained show that the navigation system eases the user’s travelling experience in complex indoor and outdoor environments. Hence, it serves as challenged people-friendly device for helping the visually impaired people to travel hassle-free and safely. The goal is to provide an effective means of navigation for the visually-impaired.
