Designing Sensor Based Smart Stick for Handicapped Person

Abstract

During their walking time, naturally handicapped persons have difficulty identifying obstructions in front of them, making it extremely unsafe. The smart stick is designed to help kids recognize the environment around them. The obstruction is not detected in normal stick, and it is ineffectual for vision impaired people. Because a blind individual has no idea what kinds of things or objects are in front of him. The application of Arduino on an ultrasonic blind walking stick will be explained in this study. According to the World Health Organization, 30 million people are irreversibly blind, with 285 billion people visually handicapped. When you take those persons, you will quickly see that they cannot walk to their destination without the assistance of others, and that they must ask for instructions. They are confronted with additional problems in their daily lives. This blind stick makes walking incredibly safe for someone who can't see. This stick detects an item in front of the user and responds to the user by vibrating or issuing a command, allowing the man to navigate without fear. This device will be the most effective way for them to overcome their issues. A person can walk more confidently with the help of this blind stick. We're planning to improve the project by expanding its scope. The Arduino embedded system, vibration motor, ISD1932 flash memory, and two ultrasonic sensors will all be used in this project. Now, this smart stick will contain an ultrasonic sensor to detect distance from any object, as well as an RF remote for the blind guy to locate his stick remotely. The stick detects all obstacles within a 4 meter range in 39 milliseconds and sends a corresponding respect message, allowing the blind to walk twice as fast as usual since she/he feels secure.
