Prototype Development of an Assistive Smart-Stick for the Visually Challenged Persons

Abstract

For visually challenged people, getting from one place to another is one of the most challenging jobs. Whether going indoors or outside, they typically require help from humankind. The lives of visually impaired persons are made more difficult by the environment's inadequate conditions. To overcome such hazards as hitting with obstacles, holes, stairs, or slipping on wet ground, a blind person must always be alert. In the event of an emergency, they might have to send an alarm message to their family or friends who are close by. In light of the preceding, we have addressed all of these difficulties in this study and provided a solution to help visually challenged people live freely. The ultrasonic sensor in our system helps blind people to notice obstacles such as holes and stairwells, while a water sensor detects water. The smart stick's buzzer goes off when any hindrance is recognized. The GPS and GSM components in our framework assist the users in determining the precise location of the smart stick. An Arduino UNO is used to control the device in this setup. The smart stick that has been recommended is a low- cost device that responds quickly, is simple to use, and consumes minimal energy.
