Abstract:
According to a survey conducted in 2020, approximately 39 million individuals worldwide are
blind, while 237 million have MSVI which is an abbreviation of Moderate to Severe Vision
Impairment. Major issue for blind persons is avoiding impediments on their way to their
destination. Such folks require support from persons with good eyesight or from a regular
walking cane. When you consider them, you'll see that they can't travel to their desired location
without the assistance of others or a smart device. They confront numerous hurdles in their
daily life. To address these and other issues experienced by blind people, we devised the idea
for this system, which is to design and develop a smart stick that can assist them in their
everyday tasks and allow them to travel more simply and confidently. This smart stick for blind
persons is made up of a number of electronic components that allow it to function. Multiple
ultrasonic sensors, a gyroscope, a GPS module, an LDR sensor, a water sensor, a fire sensor,
and other electronic components are among them. Every component has its own significance
like the ultrasonic sensor is helpful in detecting obstacles in the blind's way, gyroscope will be
used to monitor the orientation ofthe stick in case of any sort oftrouble, GPS module is used
to send the blind's location to any ofhis relatives in case ofan emergency, and the three sensors
will be used to detect different events in order to give the blind an alert. We've also linked this
smart stick to a smartphone application, to enhance its functionality and use
