Navigation Aid for Blind People

Electronics and Communication Engineering

There are about 2.2 billion people with vision impairment or blindness. Visually impaired people face a lot of challenges in their day-to-day life. Physical movement is, in fact, one of the greatest challenges. Blind people find it very difficult to merely walk around high traffic areas or any unfamiliar places and therefore have to take help from other sighted individuals. To move around in familiar places, visually impaired people usually memorize the area and where the things are kept. However, those things if moved to some other place might cause issues for blind people. The most widely used way blind people use to travel from one place to other is the white cane. With all the technological developments, certain devices have been developed to help visually impaired people to move freely around in the environment. This paper presents a systematic literature review for some of the devices developed for navigation purpose of blind people.
