Il \LaTeX{} come soluzione al problema dell'accesso a testi con formule da parte di disabili visivi

In this paper we present the problem of accessibility of texts with formulae by visually impaired people. We provide a brief overview about assistive technologies and about some current solutions of this problem highlighting limits and lacks. We analyze the use of \LaTeX{} regarding both the reading and the writing of texts with formulae by visually impaired people, remarking that it seems to be the more efficient and promising solution. Specifically, we analyze the features that make it very suitable in this context, its teaching in the schools and the problem of creating accessible PDF documents with this language (problem still open).
