Accessibility and Usability of a Collaborative e-Learning Application

VisualPedia is a collaborative environment proposed to facilitate the development of educational objects thought for all students, including students with different forms of disability. In this paper we briefly introduce VisualPedia and then report on the experience in the evaluation of accessibility and usability of the system prototype we have developed so far. We also discuss possible future improvements that have become evident after the experimentation with end users.
