Smart Blind Walking Stick

Abstract

Abstract: Risky situations arise when visually challenged people attempt to identify the items in front of them while crossing the roadway. The development of a smart cane with a distance measurement system is the primary goal of this project. An ultrasonic sensor serves as the system's input, and earphones serve as its output. Additionally, the device features a GPS live finding system and a blind person's navigation guidance. Through the audio output, this device will warn blind persons of any obstructions so they can proceed safely and without incident. Blindness is a condition in which there is a loss of seeing due to physiological or neurological reasons. Total blindness is the complete absence of visual light perception, while partial blindness is the lack of integration within the development of the nervus opticus or visual centre of attention.
