A PC-based Braille library system for the sightless

This paper presents a novel multiclient braille reading system developed around a single low cost personal computer. The system primarily addresses the needs of the Braille libraries, where different texts are needed to be read by different users simultaneously. Moreover, the system can simultaneously cater to different texts written in different languages. This feature makes it specially suitable for use by multilingual nationalities. The major advantage of this system is its low cost, compared to the other systems available and is specially attractive for the developing or underdeveloped countries. The paper describes the system, first from the user point of view and then presents the hardware and software design details. The system performance has been evaluated by the sightless users and has shown encouraging results
