Producing Energy Using Blind Man Stick

Abstract

We all are familiar with the problems a blind person faces while performing several daily life activities. These problems are generally related to walking on roads, walking on ramps, movement in staircases, looking for path in crowded streets and market places and many other situations. Of course, many of us come ahead to help them by guiding their way, but sometimes it becomes a matter of self-respect, or say, the person is not willing to take help from others or even it is possible that nobody may be available to help. Think of a situation when a blind person is alone and an Electronic Travel Aid Stick suddenly stops working due to a completely discharged battery system. This paper aims to build a device that can generate that much amount of energy that is required to run the electronic systems efficiently so that it can prevent visually impaired people from suffering in difficult situations.
