Non-sequential Mathematical Notations in the LAMBDA System

  • Cristian Bernareggi
Part of the Lecture Notes in Computer Science book series (LNCS, volume 6180)


Blind people are used to read mathematical notations through sequential representations (e.g. most Braille codes represent fractions, superscripts and underscripts in a sequential pattern). In mathematics, many notations cannot be represented through a sequential pattern without a loss of suggestivity and expressiveness (e.g. matrices, polynomial division, long division, automata, etc.). This paper introduces a multimodal interaction paradigm which aims to enable blind people to explore and edit mathematical notations which cannot be represented through a sequential pattern. So far, this interaction paradigm has been implemented in the LAMBDA system.
