Description

Visually impaired people find difficulties detecting obstacles in front of them, during walking in the street, which makes it dangerous. The smart stick comes as a proposed solution to enable them to identify the world around them.  The sensor is placed at the bottom of the stick for the sake of avoiding puddles. Buzzer warning ON when any obstacle is detected.  This proposed system uses the  Arduino Uno.  The stick is capable of detecting all obstacles in the range of the ultrasonic sensor. The smart stick is of low cost, fast response, low power consumption, lightweight, and ability to fold.

This project presents the smart walking stick based on ultrasonic sensors and Arduino for visually impaired people. There are approximately 37 million people across the globe who are blind according to the World Health Organization. People with visual disabilities are often dependent on external assistance which can be provided by humans, trained dogs, or special electronic devices as support systems for decision making. Thus, we were motivated to develop a smart blind to overcome these limitations. We accomplished this goal by adding ultrasonic sensors at specific positions to the stick that provided information about the environment to the user by activating the buzzer sound. We proposed a low-cost and lightweight system designed with a microcontroller that processes signals and alerts the visually impaired person over any obstacle through beeping sounds. The system consists of obstacle detection sensors for receiving, processing, and sending signals to the alarm system which finally alerts the user for prompt action. The system was designed, programmed using Arduino IDE.
