Abstract 
One of the most important and necessary ability of human being is 
vision. Vision is provided through eyes and enables us to interact with outside 
world. But unfortunately, there are certain people who are deprived of this 
blessing – visually impaired people. As they cannot see, the certain troubles 
and limitations are inevitable for them. Walking is one of the most obvious 
activity during which visually impaired people face troubles such as colliding 
with obstacles on their way.
Introduction 
However, we can design a smart shoe which helps them to move 
comfortably in public places, to be more precise, these smart shoes will be 
able to detect the obstacles nearby with the help of special sensors and will 
warn the person with certain signals to prevent the collision. 
Methodology
Above all, we aim to design a system which is functioning in high accuracy 
and precision, which has sufficiently fast response during its operation and 
which is user-friendly, of course. After designing, we expect a device which will 
provide visually impaired person with distraction-free travel and easy interface 
with the device. Now, the comprehensive information about the components 
of our smart shoe will be given below. First and definitely the most necessary 
component of our device is Ultra Sonic Distance Sensor as we aim to detect 
the obstacles according to distance between the person’s foot and the 
obstacle. Ultra Sonic Distance Sensor, as its name suggests, is used 
to measure the distance
 
regardless of its shape, color or surface texture, and 
will use it in order to achieve detection of an approaching object.
The working principle of Ultra Sonic Distance Sensors is like following: 
the sensor sends a sound wave at a frequency above the range of human 
hearing, when the wave comes across the obstacle in a distance up to 30 
cm, it is reflected back to the sensor. According to the time taken for a wave 
to travel this distance and come back, the sensor determines the distance 
between the shoe and an obstacle. If the distance is less than the threshold
