Accessibility and Usability of Websites Intended for People with Disabilities: A Preliminary Study

Abstract

This paper reports a preliminary study evaluating accessibility and usability of a Brazilian government website-the national digital catalogue of assistive technology (CNPTA). Although since 2004 e-government information should be broadly accessible, several studies indicate that web accessibility has not been accomplished in many government websites. This study is part of a research project that analyses whether this negative outcome replicates on government websites intended for people with disabilities. The website was assessed by automated testing and the results were compared to the outcomes from user testing. The paper discusses the findings compared with past studies and not only proposes specific aspects to enhance the website, but also it outlines several points to be considered in the next steps of the research project, as well as in other research that considers web accessibility and usability for blind people.

A Systematic Mapping of Accessibility Problems Encountered on Websites and Mobile Apps: A Comparison Between Automated Tests, Manual Inspections and User Evaluations

“…Absence of labels Form fields that have no labels on their purpose. (Zitkus et al, 2016;Gonçalves et al, 2018;Loureiro et al, 2014;Galkute et al, 2020;Mounika et al, 2019;Rysavy and Michalak, 2020) 2…”

Tecnologia Assistiva para Pessoas com Deficiência Visual: uma análise da produção tecnológica no Brasil

“…Embora a deficiência visual seja a deficiência mais predominante na população brasileira, esses indivíduos enfrentam diversas barreiras e desafios diariamente, por exemplo, realizar atividades diárias, como caminhar, ler, reconhecer objetos ou pessoas (ZITKUS et al, 2016;BRITTO NETO et al, 2015). Nesse contexto, a Tecnologia Assistiva (TA) configura-se como um auxílio na execução dessas tarefas, ao minimizar os efeitos da deficiência, melhorando as capacidades funcionais dos sujeitos, possibilitando-lhes mais autonomia e inclusão social, resultando, assim, em uma melhor qualidade de vida para seus usuários (BRASIL, 2009).…”
