EXPLOITING SENSOR BASED BLIND AID FOR THE VISUALLY IMPAIRED

Abstract

For finding the way Blind individuals or Visually Impaired Person (VIP) mostly use white canes or Guide
dogs for obstacle detection and avoidance, however these 2 ancient systems have some limitation. White stick with the
ultrasonic sensor, IR sensor and ultasonic Sensor model (Arduino IC, sensors etc.) is that the boon for blind individuals.
Visually impaired individuals use their senses like bit or sound for walking in a very explicit space, that isn't doable for
out of doors walking. to beat a these issues of blind individuals, got to develop a project by using simple available
technologies. This walking stick for blind individuals that have multiple sensors, (Ultrasonic and IR) with the assistance
of sensors it's doable to reinforce a lot of options to the walking stick. At the side of this feature the system can able to
navigate the location and in case of emergency the alert notification can send to their relatives .The aim of this paper is
to research the development of a navigation aid for blind and visually impaired individuals. It's based on a sensor with
synthetic speech output. This aid is portable and provides info to the user about urban walking routes to suggests what
decisions to make. On the other hand, and so as to reduce navigation difficulties of the blind, an obstacle detection
system using ultrasounds and vibrators is added to this device. The proposed system detects the nearest obstacle via IR
Sensor and sends back vibration as a feedback to tell the blind concerning its localization. Ultrasonic sensor is most
fitted for obstacle detection and it's of low cost and has high ranging capability.
