 ABSTRACT

God gifted sense of vision to the human being is an important aspect of

our life. But there are some unfortunate people who lack the ability of
visualizing things. The visually impaired have to face many changes in their
daily life. The problem gets worse when they travel to an unfamiliar location.
Only few of the navigation systems available for visually impaired people can
provide dynamic navigation systems like guide cane, trained pet dog and eye
substitution devices etc. None of these system work perfectly for both indoor
and outdoor applications. In this project, we propose a navigation device called
as the Smart Coat for visually impaired which is focused on providing voice
output for obstacle prevention and navigation using iot and image processing.
The proposed device is used for guiding individuals who are partially sighted or
blind. This device is used to help blind people to travel with some ease and
confidence as sighted people and is connected to an android phone through
Bluetooth. It is designed which gives voice navigation based on RFID tag read
and also updates person’s location information through GSM and GPS Module
whenever needed and other sensors are used for different applications. In recent
years many research has been done in order to develop electronic travel aids for
assisting the visually impaired.
 INTRODUCTION

For achieving dreams, goals and objective in life, independence plays an

important role. Visually impaired individuals find themselves hard to go out
independently. ACCORDING to “Global Data on Visual Impairments by
World Health Organization (WHO), the population of visually impaired people
all over the world is 285 million, out of which 39 million are blind and 246
million have low vision. Dysfunction of such an important organ leads to
several difficulties. Those who are visually impaired have to face problems in
education, mobility, employment and independent living on a daily basis. But
moving around freely is probably the most difficult challenge for them as they
are not capable of depending on their own eyes. Some studies also reveal that of
the 39 million people across the globe who are blind, over 15 million are from
India thus, making the country the home to the largest population of blinds.
Researches are being conducted all over the world to help the physically
disabled people live a normal life. To help the blinds some have developed
Smart Cane while some have developed mobile application that will help them
in locomotion. Still the most prevalent technique for locomotion of the visually
impaired is the usage of White Canes. It is an ancient method.

For decades, the white cane has become a well-known attribute to blind
people’s navigation and later efforts have been made to enhance the cane by
adding a different sensor. Blind people face problem when they walk on the
street or stairs using a white cane, but they have sharp haptic sensitivity. The
digital SMART COAT will assist the blind people by supporting extra handy
manner of existence. There are numerous steering structures for visually
impaired travelers to navigate quickly and thoroughly against boundaries and
different dangers faced. Commonly, a blind user has a white cane or a steerage
canine as their mobility resource. With the advances of modern technology
many distinctive kinds of devices are support mobility of blind, known as
Electronic Travel Aids (ETAs). The essential feature of ETA for the blind
person is to get statistics at the form of the street and the placement of
limitations when they are in unknown locations. With these facts, they need to
arrive at their locations, warding off unexpected boundaries. The SMART
COAT has sensor integrated, image processing for face and object detection
along with voice assistance.
 HISTORY OF FIELD OF INTEREST

Biomedical engineering (BME) or medical engineering is the application

of engineering principles and design concepts to medicine and biology for
healthcare purposes. This field seeks to close the gap between engineering and
medicine, combining the design and problem solving skills of engineering with
medical biological sciences to advance health care treatment, also included
under the scope of a biomedical engineer is the management of current medical
equipment within hospitals while adhering to relevant industry standards. This
involves equipment recommendations, procurement, routine testing and
preventative maintenance, through decommissioning and disposal. This role is
also known as a Biomedical Equipment Technician (BMET) or clinical
engineering.

Biomedical engineering has recently emerged as its own study, as

compared to many other engineering fields. Such an evolution is common as a
new field transition from being an interdisciplinary specialization among
already-established fields, to being considered a field in itself. Much of the
work in biomedical engineering consists of research and development, spanning
a broad array of sub-fields. Prominent biomedical engineering applications
include the development of bio-compatible prostheses.
 PROBLEM STATEMENT

Guided Cane
 Difficulty while travelling.

 In cracked roads cane gets stuck in between.

 In crowded areas there is a possibility of misplaced cane.

Eye Substitution
 Eye substitution is not affordable to all.

 Usage of this is not interpreted in the right manner by all.

Pet Dog
 Training is required.

 Maintenance.

 According to its mood it works.

Considering all these reasons we have come up with these ideas.

 MOTIVATION

 As technology is improvising day by day it is focusing on the development

only on entertainment, space technology, education and security. Only
prototypes are available for the visually impaired.

 Assistive technology has designed many devices specifically to help

people with vision loss or other disabilities, everything from screen
readers , screen magnifiers , video magnifiers and other devices for reading
and writing, braille watches and braille printers .All these are not
affordable by all so taking all these parameters into consideration we have
come up with this project.
 PROPOSED WORK

Smart coat has 4 basic roles embedded in it

 Sensors are used to determine the distance of the obstacles.

 Image processing for object detection using camera for navigation purpose.

 Speech output using bluetooth and earphones.

 GSM and GPS modules for location/tracking.

 SUMMARY

Science and technology has evolved over time in various fields

especially in bio-medicals. Many wearable devices have been
introduced into the market, amongst them one of the prototype which
we have considered is SMART COAT. Some basic sensors are given as
input and camera captures images, the captured image is processed and
a speech output is produced. Whereabouts of the visually impaired is
sent to the guardian through GPS and GSM modules. Speech output is
obtained with the help of bluetooth and earphones.
