Ruman Sarkar, Smita Das . Analysis of Different Braille Devices for Implementing a Cost-effective and Portable Braille System for the Visually Impaired People. International Journal of Computer Applications. 60, 9 ( December 2012), 1-5. DOI=10.5120/9717-3073
Abstract
There are diverse tools and equipments which are proving different facilities and features for enhancing the communication skills of the visually impaired people in a great extent. For interpretation of text by the visually impaired persons, most of the devices are designed to simulate the standard Braille display where each character is characterized by six dots (made up of small metals or plastic pins) which could be vertically moved in upper or lower directions mechanically or electronically or through any other mechanism. Also for writing the contents, same standard is followed for building any Braille writer. Analyzing different updated machinery and equipments which support the visually impaired persons for their proper communication with the others, it has been found that these tools provide only some particular facility or feature and that tools sometime may not be sufficient to provide improved support. That is why it is necessary to integrate all different possible communication methods in a single system to cover the different drawbacks in the existing systems and provide a complete solution to those visually impaired people. This paper is the result of analysis of the existing tools and technologies for the enhancement of the communication of the blind people and this paper also proposes a complete system which consists of four different techniques for the blind people to enhance their communication skills. The proposed system consists of a low cost keyboard as Braille writer, a low cost tactile refreshable Braille display (named as SPARSHA), remote communication method through SMS and an Audio output system of the text. This system may provide a complete solution to different communication problem in the visually impaired person's lives.
