An Embedded System for the Visually Impaired People

Abstract

Human learn from his birth till death.Walking , eating are the examples of what a human must learn.But it is not same for all.Because if someone has no eyesight from birth then the question arises “how do they learn?”.The answer is simple - of course the speed of learning is less if compared to the other ones.Recognition, visualization, finding are not easy task for them as they are deceived from eyesight.And having some portion of sight also has some difficulties in real life.That’s why for them walking is a great problem as they can not locate the obstacles around them.And it makes them confuse and they get trouble during their movement.Not only they face the difficulty rather other people surrrounded by them also face the difficulty if they fail to detect the obstacles or the people around them.A simple solution can be to alert these two kind of people to avoid collision between them and to detect the obstacle is to make such a device that is capable of produce sound if any object comes nearer to them.The blind people or the visually impaired people can use it with the stick they use while walking or this device can be used as a handheld item.
