Smart Stick-Based Succeed Walking Activity for Visually Impaired Individuals

Abstract

Visual impairment, which means that a person’s eyesight cannot be corrected to the normal level, is the curse. If individuals are partially blind, they have limited vision and may have blurry vision or an inability to distinguish the shapes of objects. Complete blindness means individuals cannot see at all. Worldwide there has a large visually impaired population, and a large part is in developing and emerging countries. Vision difficulty always makes a person’s life hard, and poorness adds a new dimension. Technology is advancing and aids, like all other sectors, visually impaired individuals in performing daily activities, including walking to travel distances. Most of the technologies are costly and difficult to bear for poor visually impaired individuals, especially people in emerging and developing countries. This research aims to develop a cost-effective technology to aid visually impaired individuals. We implemented the system using a microcontroller, sonar sensor, micro coin vibration motor, and light-depending resistor as the main components. The results demonstrate that the developed technology can aid visually impaired individuals and add new facilities if there have hearing disabilities. The developed cost-effective technology, therefore, provides the best solution for a large number of visually impaired individuals.
