    Abstract: Este mapeamento buscou conhecer como, quando e onde aspectos de acessibilidade e usabilidade são abordados durante o desenvolvimento de jogos digitais para usuários idosos. Abordamos 20.270 resultados iniciais, amostramos 1.755 e identificamos 46 publicações após o processo do mapeamento. Os resultados deste mapeamento mostraram uma preferência em pesquisas que abordem avaliação de acessibilidade e de usabilidade neste domínio. Este mapeamento também evidenciou que, neste domínio e na amostragem considerada, pesquisas apenas abordaram acessibilidade quando usabilidade também foi abordada por alguma razão. Ainda, as análises de resultados indicaram a predominância significativa ($\chi^2 = 45.9103$, $p-valor 〈 .01$) de abordagens que consideram usabilidade (43) sobre abordagens que consideram acessibilidade (11). Neste contexto, sugerimos questões de pesquisa para revisões sistemáticas futuras na área.

    Abstract: The use of the web to provide government information and services to citizens has become more and more significant. Ensuring that any citizen can access these contents and services is essential, regardless of disabilities or other barriers they may have. In Brazil, Executive Act no. 5.296/2004 ruled that all government agencies should adapt their websites according to accessibility guidelines until December 2005. In order to check the trend of accessibility over the years and the impact of such legislation, this article analyzes the accessibility of the Brazilian state government websites from 1996 to 2007. Analyses were carried out by means of metrics, obtained by evaluations with automatic tools. The results indicate that the legislation has had little impact on the accessibility of the sites, with an improvement in 2007. Thus, it indicates that it is necessary to adopt more effective public policies to guarantee that people with disabilities have insured their rights to access information and public services on the web.

    Abstract: Atualmente milhões de indivíduos em todo o mundo enfrentam diariamente dificuldades devido à falta de recursos acessíveis para obterem informações. Tendo em mente esse problema foram criados diversos conjuntos de diretrizes de acessibilidade com o intuito de orientar, por meio de recomendações, a criação de programas e conteúdos web mais acessíveis. Entretanto, tais conjuntos de diretrizes geralmente estão relacionadas com definições genéricas de deficiências e muitas vezes é difícil identificar quais diretrizes são mais adequadas para certos tipos de deficiências. Este trabalho propõe o uso do sistema denominado SEDA (Sistema para Exploração de Diretrizes de Acessibilidade) para auxiliar tanto na identificação de deficiências, para as quais não foram criadas diretrizes de acessibilidade específicas, quanto na identificação dos limites existentes ao se associar diretrizes de acessibilidade a deficiências. Nós também apresentaremos resultados de um estudo de caso baseado em um protótipo, demonstrando que o sistema pode auxilia pesquisadores na exploração de diretrizes de acessibilidade e apontando algum problemas na ontologia de deficiências da Organização Mundial de Saúde.

    Abstract: The constant evolution of the Web has covered various segments of society and, as it evolves, its content must be accessible to different users’ profiles. Older adults (60+) are the fastest growing population of users who face difficulties in interacting with websites, due to limitations in their abilities caused by the aging process. Despite the legislation and guidelines established for the development of accessible and usable web contents, several problems of accessibility and usability still must be solved. In particular, most website designers do not take into account the older adult’s profile. This paper introduces Sene-check checklist, a support to web accessibility and usability evaluations for the Brazilian older profile developed according to scientific procedures, including the following three perspectives: (1) literature review, (2) point of view of experts and developers and (3) point of view of Brazilian older adults. The results enabled an investigation into the main problems encountered by older adults regarding web interaction and reinforced the relevance of a support for the evaluation of web accessibility and usability.

    Abstract: A educação remota emergencial tornou-se a principal alternativa para manter o processo de ensino e aprendizagem ativo com o isolamento social ocorrido como consequência da pandemia da COVID-19. Apesar de muitas instituições de ensino superior terem pouca ou nenhuma experiência com esta modalidade de ensino, elas tiveram que adequar suas metodologias rapidamente e adotar ferramentas que permitissem a comunicação síncrona e assíncrona entre professores e estudantes, a disponibilização de material didático e a realização de atividades didáticas. A acessibilidade digital torna-se imprescindível neste contexto, para permitir que todos os estudantes, incluindo estudantes com deficiência, tenham acesso ao aprendizado de forma igualitária. O objetivo deste artigo é apresentar um diagnóstico sobre as tecnologias e outros recursos disponíveis nas instituições de ensino superior federais e estaduais brasileiras para dar suporte ao ensino remoto emergencial durante a pandemia da COVID-19, com foco no provimento de acessibilidade digital. A metodologia utilizada foi a solicitação de informações por meio da Lei de Acesso à Informação a 142 instituições, com análise dos dados de 97 respostas completas ou parciais. Os resultados mostraram que a maioria das instituições possui dados sobre estudantes de graduação com deficiência e muitas utilizam ferramentas de software e recursos acessíveis, com número menor de instituições que mantém registro sobre alunos de pós-graduação com deficiência. A maioria das instituições que respondeu aos pedidos utiliza abordagens de ensino remoto durante o período da pandemia. Os resultados detalham a capacidade instalada nas instituições para suporte à acessibilidade digital para os alunos nesse contexto, como a preparação de Ambientes Virtuais de Aprendizagem, acessibilidade de conteúdos multimídia, profissionais especializados (como tradutores-intérpretes de língua de sinais), acessibilidade de livros digitais e recursos de Tecnologia Assistiva.  O estudo conclui que um grande avanço já foi realizado nas instituições de ensino superior públicas no Brasil para melhorar a acessibilidade.  Entretanto, muitas instituições precisarão adequar-se para dar prosseguimento ao uso de recursos educacionais digitais que devem ter crescimento após a experiência com ensino remoto na pandemia e prover acessibilidade adequada.

    Abstract: Mobile devices have gained more attention from the society that is using them increasingly for a variety of purposes. For complete insertion of the population in this constant digital evolution it is fundamental that mobile applications also offer access to different user profiles, regardless of their disabilities or limitations. Considering quality, productivity, and speed of application creation, there is a wide range of good development practices and evaluations. However, methods that involve usability and accessibility are still developing. The purpose of this article is to present the Acc-MobileCheck, which is a checklist of accessibility and usability for mobile devices apps, based on good software development practices and guided by Design Patterns. The Acc-MobileCheck, composed of 47 verification items, consists of questions that look for evidence of problems of comprehension, operation, perception, and adaptation in mobile apps. The evaluation method aims to address difficulties that can be faced by people with hearing, visual, intellectual, or mobility impairment. Five experts and three developers of mobile apps had evaluated the Acc-MobileCheck. The conclusive results show that the checklist is usable and includes essential issues for the evaluation of accessibility and usability. The data obtained allowed a restructuring of the evaluation method developed, and the positive comments about the checklist demonstrate its adequacy to attend the demand.

    Abstract: The Web 2.0 brought new requirements to the architecture of web systems. Web applications’ interfaces are becoming more and more interactive. However, these changes are severely impacting how disabled users interact through assistive technologies with the web. In order to deploy an accessible web application, developers can use WAI-ARIA to design an accessible web application, which manually implements focus and keyboard navigation mechanisms. This article presents a quantitative metric, named Fona, which measures how the Focus Navigation WAI-ARIA requirement has been implemented on the web. Fona counts JavaScript mouse event listeners, HTML elements with role attributes, and TabIndex attributes in the DOM structure of webpages. Fona’s evaluation approach provides a narrow analysis of one single accessibility requirement. But it enables monitoring this accessibility requirement in a large number of webpages. This monitoring activity might be used to give insights about how Focus Navigation and ARIA requirements have been considered by web development teams. Fona is validated comparing the results of a set of WAI-ARIA conformant implementations and a set of webpages formed by Alexa’s 349 top most popular websites. The analysis of Fona’s value for Alexa’s websites highlights that many websites still lack the implementation of Focus Navigation through their JavaScript interactive content.

    Abstract: Widgets have been deployed in rich internet applications for more than 10 years. However, many of the widgets currently available on the web do not implement current accessibility design solutions standardized in ARIA (Accessible Rich Internet Applications) specification, hence are not accessible to disabled users. This article sets out an approach for automatically identifying widgets on the basis of machine-learning algorithms and the classification of mutation records; it is an HTML5 technology that logs all changes that occur in the structure of a web application. Automatic widget identification is an essential component for the elaboration of automatic ARIA evaluation and adaptation strategies. Thus, the aim of this article is to take steps toward easing the software-engineering process of ARIA widgets. The proposed approach focuses on the identification of drop-down menu widgets. An experiment with real-world web applications was conducted and the results showed evidence that this approach is capable of identifying these widgets and can outperform previous state-of-the-art techniques based on an F-measure analysis conducted during the experiment.

    Abstract: Serious games are a promising tool in different scenarios, such as education and health; however, there has been little research reported on their specialized use for older adults. We created a digital cognitive test – with the characteristics of a serious game – using Unified Design aiming to reproduce digitally the results of clinical cognitive evaluation in older people. The digital cognitive test was submitted to two validation experiments targeting an older public (n=40) with little experience in dealing with tablets or smartphones. The first experiment did not show significant correlation, but from it, we implemented initiatives to simplify the tests, which brought a positive result regarding convergence analysis in the second experiment. We concluded that it is possible to use digital games as cognitive tests adapted to the needs of older adults to achieve similar results as those of paper-based cognitive tests.
