In this paper, we describe the proposal of an open-source and open access website designed to share a set of web accessibility guidelines for people with Autism Spectrum Disorder (ASD) called GAIA, that intends to help web developers to design accessible web interfaces for these users. The guidelines were extracted from a revision process of 17 works published between 2005 and 2015 including international recommendations, commercial or academic software and peer-reviewed papers. We identified 107 guidelines that were grouped in 10 categories through affinity diagram technique. Then, we normalized the guidelines in each group according to similarities and duplicated statements, generating a set of 28 guidelines. As a result, we evidenced best practices to design accessible web interfaces for people with ASD based on well succeeded solutions presented in works of different contexts. With those results, we aim to contribute to the state of the art of cognitive web accessibility. Therefore, we made the set of guidelines available in a repository on GitHub, so it can be used both by researchers and technical professionals. Resumo.Neste artigo, descrevemos a proposta de um website de código e acesso abertos projetado para divulgar um conjunto de recomendações de acessibilidade web para pessoas com Transtorno do Espectro do Autismo (TEA) chamado GAIA, o qual tem a intenção de auxiliar desenvolvedores web a projetar interfaces web mais acessíveis a estes usuários. Estas recomendações foram extraídas através de um processo de revisão de 17 trabalhos publicados entre 2005 e 2015, incluindo recomendações internacionais, softwares comerciais ou acadêmicos e artigos revisados por pares. Identificamos 107 recomendações que foram agrupadas em 10 categorias através da técnica de diagrama de afinidades. Em seguida, normalizamos as recomendações em cada categoria de acordo com similaridades e declarações duplicadas, gerando um conjunto de 28 recomendações únicas. Como resultado, evidenciamos melhores práticas para projetar interfaces web acessíveis a pessoas com TEA baseado em soluções de sucesso presentes em trabalhos de diferentes contextos. Com estes resultados, esperamos contribuir com o estado da arte de acessibilidade web cognitiva. Dessa forma, disponibilizamos as recomendações em um repositório no GitHub, para que estes resultados possam ser utilizados tanto por pesquisadores quanto por profissionais técnicos.

Cognitive disabilities include a diversity of conditions related to cognitive functions, such as reading, understanding, learning, solving problems, memorization and speaking. They differ largely from each other, making them a heterogeneous complex set of disabilities. Although the awareness about cognitive disabilities has been increasing in the last few years, it is still less than necessary compared to other disabilities. The need for an investigation about this issue is part of the agenda of the Challenge 2 (Accessibility and Digital Inclusion) from GranDIHC-Br. This paper describes the results of an online exploratory survey conducted with 105 web development professionals from different sectors to understand their knowledge and barriers regarding accessibility for people with cognitive disabilities. The results evidenced three biases that potentially prevent those professionals from approaching cogni-tive disabilities: strong organizational barriers; difficulty to understand user needs related to cognitive disabilities; a knowledge gap about web accessibility principles and guidelines. Our results confirmed that web development professionals are unaware about cognitive disabilities mostly by a lack of knowledge about them, even if they understand web accessibility in a technical level. Therefore, we suggest that applied research studies focus on how to fill this knowledge gap before providing tools, artifacts or frameworks.
