Arduino-Powered Smart Stick for Empowering the Visually Impaired

Abstract

The purpose of this paper is to discuss the design and development of a smart stick for visually impaired persons or blind people. This smart stick is an innovative assistive technology device that is aimed to improve mobility and independence for individuals who are visually impaired. Through the usage of headphones, an ultrasonic sensor is utilized for the purpose of detecting obstacles that may be in the path of a blind individual. Additionally, the voice kit provides the user with a spoken message in order to inform them. For the purpose of controlling the design system, an Arduino is utilized. This stick is used by the blind person for safe navigation, and it is able to detect objects within a range of distance that is between two centimeters and four hundred centimeters. The Global System for Mobile Communications (GSM) and Global Positioning System (GPS) modules are utilized in this suggested paper to relay alarm messages and locations in the event of an emergency.
