e-Vision: An Innovative Electronic Travel AID (ETA) sor Visually Impaired
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
Blind people face every day problems in commuting from one place to another, be it indoors or out on the road. This paper presents an ultrasonic sensor which detects obstacles in the way. A voice recognition system identifies the voice and according to input processes the destination. This paper presents an electronic navigation system for visually impaired and blind people (subject). This system understands obstacles around the subject up to 500 cm in front, left and right direction using a network of ultrasonic sensors. This proposed system uses ATMEGA32 microcontroller based embedded system to process real time data collected using ultrasonic sensor network. The RFID section uses an array of cheap RFID cards which stores location address data, the RFID reader (pen shaped) reads data from the cards according to the user voice input. The outpit of this a GPS type speech navigation system.
