Study, Design and implementation of a solar smart stick for blind people

Abstract

There are different techniques, tools and technologies available to enable disabled from carrying
out their daily activities, one of the most used tools is the white stick which allows the user to detect
obstacles that are approximately one meter from him and also to detect the state of the ground on which
they walk. However, there are still constraints to detect higher obstacles as well as to touch them and
recognize them, which makes the visually impaired unsociable. Sensor technology allows us to identify
physical quantities and transform them into information thanks to knowledge of the physical phenomena
that occur there. Understanding waves has made it possible to develop sensors that can detect objects at a
distance through the analysis of received echoes.
These systems have several drawbacks, which are based on a simple adaptation of the devices designed for
motorists and are therefore unsuitable or poorly suited to a pedestrian, also visually impaired.
The main objective of these studies is to create an intelligent cane for people suffering from blindness visual
by using several sensors. On the other hand, is monitored by using solar energy.
