Smart Blind Stick for Obstacle Detection

Abstract

The Smart Blind Stick for Obstacle Detection discussed here is mainly for visually impaired people. In this system, we have developed a stick which consists of ultrasonic sensor, Arduino uno, buzzer, vibration motor, RX-TX transistor which will help blind people to detect obstacle and water present on their path to their destination. 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 work 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 with the help of sensors working in a manner to avoid obstacle, warn the blind person about the water in front of him/her and locate the stick in emergency situation. 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 with most efficient and effective algorithms which make it very helpful for the visually impaired people.
