8-dot Braille Code for Complex Nemeth Symbols

Abstract

The aim of the present study was to specify transition rules from the 6-dot to the 8-dot braille code regarding advanced mathematical and scientific notation as they are determined in the Nemeth braille code. A generic design methodology was used to transform 6-dot braille scien- tific characters into 8-dot braille code for a specific set of scientific symbols. In total, 24 rules were developed and used to transcribe the modifiers as they are described in the Nemeth code (i. e. symbols that appear directly over or directly under another symbol, such as the small arrow sometimes used above a letter that represents a vector). The results indicated that the specific method has the potential to claim generalization in terms of validity and reliability by implementing stages of modification, de- bugging, coherence and consistency.
