A low cost microelectromechanical Braille for blind people to communicate with blind or deaf blind people through SMS subsystem

Abstract

Due to the lack of vision, the blind people cannot easily access the latest information and the technologies which can provide them an alternating communication expertise. Modern technological enhancements cannot be easily affordable to the visually impaired people because of their higher cost and the less portability. That is why it has become pretty necessary to develop a low cost, portable and a fast Braille System for the visually impaired people. This paper introduces a new communication channel for the deaf blind and visually impaired people which consist of three different subsystems providing different facilities to improve the communication skill of the visually impaired people. The system consists of the following three modules: i) a portable low cost refreshable Body-Braille system for displaying Braille characters using six micro vibrators. ii) an easy Braille writer for writing the Braille characters and iii) a remote communication system through SMS. This new communication system is cheap, portable, fast and accurate.
