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.
