Abstract

Accessibility is the possibility of any person to make use of all the benefits of society, including the Internet. As the interfaces are typically graphic, sites can be an obstacle for visually impaired persons to access. For a site to be accessible to blind persons it’s necessary the information contained in the visual resources be reproduced by means of an “equivalent” textual description, capable of transmitting the same information as the visual resources. This study is aimed at identifying and defining usability guidance compliant with accessibility W3C directives that can facilitate the interaction between visually impaired and Internet and still guarantee sites with understandable navigation content. Towards this end an exploratory study was conducted, comprised of a field study and interviews with visually disabled people from Instituto Benjamin Constant, reference center in Brazil for the education of visually impaired persons, in order to get to know these users better.
