Acessibilidade para deficientes auditivos na web: um estudo de caso nos sistemas solar e sigaa/ufc

Abstract

Access to higher education, together with the recognition of the Brazilian Sign Language as a legal means of communication, enabled deaf people to occupy spaces within the academic community. Furthermore, the use of assistive technologies and the evolution of the Web allow students with different levels of deafness to follow classes, reducing the interference of physical barriers. Despite this, the content made available virtually needs to follow specific guidelines so that it can be considered effective. This study aims to carry out a case study of the Solar and SIGAA/UFC virtual environments, from the perspective of a person with hearing impairment, following the criteria of the Accessibility Guidelines for Web Content and attesting their level of compliance based on the criteria settled down. First, the state of the art on works focused on teaching people with hearing impairment through digital technologies was surveyed. Then, it was determined which evaluation criteria applicable to deaf people would be necessary to meet the target audience of the study. After this step, manual tests were performed to validate the necessary techniques established by WCAG for each requirement. The results of the study indicate that both systems meet the minimum compliance requirements for people with hearing loss, however there are points of improvement that can be achieved in order to enable greater teaching effectiveness.
