A semi-automatic support to adapt e-documents in an accessible and usable format for vision impaired users

Electronic material (e-documents, e-books, on line resources, etc.) represents an essential tool for continuous learning for print-impaired people, provided it is well-structured. To obtain accessible and usable e-content, specific requirements should be applied from the early beginning or used when adapting existing electronic formats. In this paper we present a method, and a first associated prototype, for making e-documents in a format, which is accessible and usable for vision impaired users. The resulting environment is composed of various transformations, with different degree of automation, and applies a number of guidelines that have been defined for this purpose.
