Passenger BUS Alert System for Easy
Navigation of Blind
[attachment=67583]
Abstract:
Talking signs, guide cane, echolocations are all useful in
navigating the visually challenged people to reach their
destination, but the main objective is not reached that it fails to
join them with traffic. In this project we propose a bus system
using wireless sensor networks (WSNs).The blind people in the
bus station is provided with a ZigBee unit which is recognized by
the ZigBee in the bus and the indication is made in the bus that
the blind people is present in the station. So the bus stops at the
particular station. The desired bus that the blind want to take is
notified to him with the help of speech recognition system
HM2007. The blind gives the input about the place he has to
reach using microphones and the voice recognition system
recognizes it .The input is then analyzed by the microcontroller
which generates the bus numbers corresponding to the location
provided by the blind. These bus numbers are converted into
audio output using the voice synthesizer APR 9600. The ZigBee
transceiver in the bus sends the bus number to the transceiver
with the blind and the bus number is announced to the blind
through the headphones. The blind takes the right bus parked in
front of him and when the destination is reached it is announced
by means of the GPS-634R which is connected with the controller
and voice synthesizer which produces the audio output. This
project is also aimed at helping the elder people for independent
navigation.
INTRODUCTION
Out the 6.7 billion people that populate the world,
161 million are visually impaired. Each visually impaired
individual faces different challenges based on their specific
level of vision. With the rise of various support-based
organizations, more visually impaired people have been given
the opportunity to education and many other means. But still
the issues of navigation for the blind are very complex and
troublesome especially when they walked down in street and
also navigate to distant places by public transport system. For
a visually impaired person, doing things such as reading traffic
signals and street signs can be extremely challenging, if not it
is impossible to do.
