Abstract:
The smart walking stick based on ultrasonic sensors and Arduino for visually impaired
people. There are approximately 37 million people across the globe who are blind according
to the World Health Organization. People with visual disabilities are often dependent on
external assistance which can be provided by humans, trained dogs, or special electronic
devices as support systems for decision making. Thus, we were motivated to develop a smart
white cane to overcome these limitations. We accomplished this goal by adding ultrasonic
sensors at specific positions to the cane that provided information about the environment to
the user by activating the buzzer sound. We proposed low cost and light weight system
designed with microcontroller that processes signal and alerts the visually impaired person
over any obstacle, water or dark areas through beeping sounds. The system consists of
obstacle and moisture detection sensors for receiving, processing and sending signals to the
alarm system which finally alerts the user for prompt action. The system was designed,
programmed using C language and tested for accuracy and checked by the visually impaired
person. Our device can detect obstacles within the distance of about 25cm and 10cm from the
user. This paper describes the working of a Blind Stick based on a microcontroller
ATmega328 (Arduino Uno). Most monitoring systems that are in use in the present world
works in disconnected mode yet our framework is planned with the end goal that a patient
can be checked remotely progressively. Shrewd stick for visually impaired man is a machine
that can pursue a way. The way can be unmistakable like a dark line on a white surface (or
the other way around) or it very well may be undetectable like an attractive field. Detecting a
line and moving the robot to remain on course, while always redressing incorrectly moves
utilizing criticism component frames a basic yet compelling shut circle framework. As a
software engineer you inspire a chance to 'educate' the robot how to pursue the line
consequently giving it a human-like property of reacting to improvements.
Description:
Vision is the most vital piece of human physiology as 83% of data individual
gets from the earth is by means of sight. The 2011 measurements by the World
Health Organization (WHO) evaluates that there are 285 billion individuals in
world with visual debilitation, 39 billion of which are visually impaired and 246
with low vision. The conventional and most seasoned portability helps for
individuals with visual debilitations are the strolling stick (additionally called
white stick or stick) and guide hounds. The most critical disadvantages of these
guides are essential aptitudes and preparing stage, scope of movement and next
to no data passed on. With the quick advances of current innovation, both in
equipment and programming front can possibly give shrewd route abilities. As
of late there has been a ton of Electronic Travel Aids (ETA) structured and
conceived to enable the oblivious in regards to explore freely and securely.
Additionally top of the line innovative arrangements have been acquainted as of
late with help dazzle people explore freely. While such frameworks are
appropriate for outside route, because of the requirement for observable pathway
access to satellites, regardless they require extra parts to enhance the goals and
nearness discovery to avert impact of the visually impaired people with different
articles and subsequently subject his/her life to risk. Anyway in contrast with
different innovations many visually impaired direction frameworks use
ultrasound as a result of its invulnerability to the ecological clamor. Another
motivation behind why ultrasonic is well known is that the innovation is
moderately economical, and furthermore ultrasound producers and locators are
little enough to be conveyed without the requirement for complex hardware. The
venture depends on a hypothetical model and a framework idea to give a shrewd
electronic guide to daze individuals.
