Abstract: | At present, it is recognized that the Internet plays key role in universalization of opportunities in society in which we live. For people with disabilities, the content must be accessible in all websites, but the assistive technologies used must be adequate to the specific needs of people with disabilities. Dosvox is a free system developed in the Universidade Federal do Rio de Janeiro (UFRJ) specially designed for blind people and used by them in the performance of their tasks with the use of computers. Previously, through exploratory research based on the observation of the interaction of blind students with the Web, usability problems were identified in the Dosvox interface and in the Webvox, the Web browser included in the system, and these problems were related to the fact that the interface is designed in accordance with the mental model of these Information Technology professionals. This study consolidate the problems in earlier phases of the research, link the results with usability heuristics of Nielsen and propose several improvements to Dosvox and its development process. |
