Avaliação do nível de acessibilidade das plataformas digitais para pessoas com deficiência visual. caso de estudo: plataforma educacional SIGA da UEM (2025)

Abstract

This study aims to evaluate the accessibility level of the educational platform Integrated Academic Management System (SIGA) of Eduardo Mondlane University (UEM) for students with visual impairments, considering the barriers faced in accessing essential academic services. Methodologically, the study adopts a mixed-methods approach, using triangulation of data obtained through manual tests performed by students with visual impairments, automatic accessibility tests with specific tools, and direct observation of the participants' interaction with the SIGA platform. The sample consisted of 10 students with visual impairments from UEM, belonging to different undergraduate courses, who performed essential academic tasks, such as checking grades, registering, and consulting subjects. The results reveal that students with visual impairments face difficulties using the SIGA platform, stemming from accessibility barriers such as links and buttons without accessible descriptions, failure to read grades and subjects by screen readers, and keyboard navigation without a logical sequence. These barriers demonstrate that the platform does not adequately respond to the assistive technologies used by students, showing non-compliance with fundamental criteria of the Web Content Accessibility Guidelines (WCAG). Quantitative data indicate that 60% of students rate the platform as being poorly accessible, which shows a low level of accessibility, compromising the autonomy of students with visual impairments. It is concluded that the SIGA platform is not fully accessible and needs to be reviewed and adapted to promote digital inclusion and ensure equitable access to academic services. The study proposes improvements, highlighting the rigorous implementation of WCAG guidelines and the inclusion of students with visual impairments in platform testing.(TRADUÇAO NOSSA)
