Interfaces acessíveis no moodle baseadas no padrão WCAG 2.0 para alunos cegos

Abstract

This work is part of the development of research online Educational Technology Network, the Graduate Program in Educational Technology Network of the Federal University of Santa Maria, conducting an investigation based on a case study, qualitative, proposing the development of accessible interfaces on the AVEA Moodle. From the blind user's perspective, the objective is to develop accessible interfaces in accordance with the principles defined by the WCAG 2.0 accessibility standard. The theoretical framework behind information related to Visual Impairment, Assistive Technologies, Web accessibility, Web Application Design and Web Development Standards. During the observations and analyzes were listed all the elements for the format, resources and environment activities that may suffer some change to meet the principles proposed by WCAG 2.0. After the records from the observations and analyzes made by the blind student, subject of this research, he elaborated the final product of this dissertation, the AVEA Moodle interface design, containing the user's characteristics, definition of use cases, prototype mapping goals, defining the set of tasks associated with each action, screen images development for each share of interface and identification of user interface objects used in the implementation. After preparing the final design Web interface, it moved to the implementation phase of the survey recorded changes, following the development of standards for web accessibility. After the implementation process, finalized to research by performing the validation process following two scenarios with different technologies using the browsers Internet Explorer and Google Chrome, and the screen reader Jaws and NVDA, respectively. Research has shown through the made observations and analyzes that, in this scenario, much remains to be done, but many of these obstacles are solvable. The weaknesses relating to the accessibility of the AVEA Moodle interface identified in the survey, confirm the belief that various aspects of accessibility can only be detected by blind users, confirming the importance of manual validation.
