Towards the 8-dot Nemeth Braille code

Abstract

In this work, a language-independent design methodology for the systematic development of an 8-dot braille code, has been applied to the Nemeth code. First, we set the design principles: compression, intra-similarity, inter-similarity, unambiguity, consistency and foresight. Then, we follow the Nemeth principles: non enclosure, just in time information, be true to the print, good mnemonics and continuous notation. Finally, we introduce 24 transition rules from 6- to 8-dot Nemeth code. Indicative results of the methodology are also presented. © 2014 Springer International Publishing.
