Development of e-stick for blind persons using IoT

Abstract

The blind and impaired people are suffering a lot because there are so many struggles for blind peoples to reach their destination and also there are dangerous risks that blind persons must face. To avoid uncomfortable walking experience, we have designed a smart electronic walking stick for blind people. Our paper proposes a low-cost walking stick based on latest technology and a new implementation are made for efficient interface for blind people. Basically, the ultrasonic sensor is implemented in the walking stick for detecting the obstacles in front of the blind/impaired persons. If there are any obstacles, it will alert the blind person to avoid that obstacle and the alert in the form of voice announcement. Daily in different aspects in order to provide flexible and safe movement for the people. In this technology driven world, where people strive to live independently, this paper propose a low-cost 3D ultrasonic stick for blind people to gain personal independence, so that they can move from one place to another easily and safely. A portable stick is design and developed that detects the obstacles in the path of the blind using ultrasonic sensors. The voice announcement is activated when any obstacle is detected. In addition, the stick is equipped with an SMS message system. SMS system is used by the blind to send SMS message to the saved numbers in the microcontroller in case of emergency. The programming of voice announcement has been successfully done for this system. Computer simulation is done to essence the performance of the system using Proteous software.
