Ultrasonic Blind Stick with GPS Tracking System and Vibration Feature

Abstract

God has gifted five important sense organs to lead a convenient life. Of which vision plays a very important aspect of our life. But there are many people who lack this visualizing ability. In recent survey it is clear that out of 39 million blind people across the globe 12 million blind people are from India. The blind people use conventional white cane to move from one place to another. These blind sticks are capable of finding obstacle when the stick touches them physically. Hence blind people face a major problem when they walk on stairs using white cane. Using advanced technology we propose an ultrasonic blind stick with GPS tracking feature along with vibration for blind people for their more convenient means of life. Here in this project we have designed the blind stick with five important advanced features. The blind person can sense the object before the stick touches the object physically using ultrasonic sensor. The blind person can know whether there is water in front of him/her which is one of the important features. Also the person can know whether there is light or darkness around them. If the person loses the stick it can be found by using RF remote. Since we are using vibration motor there are various patterns of vibration along with different beep signals for individual features. The most important feature is that we are using GPS tracking system so that the person can be found whenever he/she is in trouble or being lost.
