A Survey on Smart Blind Stick for Obstacle Detection

Abstract

The main drawback with blind individuals is to travel a way to their destination where they require to travel. Such individuals would like help from others with sensible sight. As represented by World Health Organization, 10 percent of the visually impaired don't have any practical sight in the least to assist them move around while seeking no help. This study proposes a new technique for designing a smart stick to help visually impaired people that will provide them obstacle free navigation. The proposed system intended to provide low cost and efficient navigation aid for the blind. It gives a sense of artificial vision by providing information about the environmental scenario of objects around them. The main concern is to help visually challenged people to navigate with ease using advance technology. Physical movement could be a challenge for visually impaired persons, because it can become tricky to distinguish where he/she is, and how to get, where he wants to go, from one place to another. In this technology-controlled world, where people strive to live independently, this project proposes an ultrasonic stick for blind people to help them gain personal independence. This paper also surveys different systems proposed by different authors which include different sensors. Each systems has its own cons and pros which make them different from each other and our proposed systems include the most efficient and effective algorithms which make it very helpful for the visually impaired people
