Content Accessibility

En la actualidad, las personas dependen en gran medida de las tecnologías de la información para realizar su trabajo, acceder contenidos para la formación académica o entretenimiento. En este contexto, los contenidos que ofrecen los sitios web deben ser compartidos entre distintos individuos. Para lograr que los contenidos sean percibidos por todas las personas, incluyendo aquellas que tienen alguna discapacidad, se requiere que los sitios web sean accesibles. El término accesibilidad denota el grado en el cual un sistema puede ser usado por personas con el más amplio rango de capacidades. El objetivo de este trabajo, por tanto, es presentar EvA-Web (Evaluación de la Accesibilidad-Web) como una herramienta que apoya a los desarrolladores de software en la identificación de las barreras a la accesibilidad que se encuentran en los sitios web que diseñan o programan. El prototipo de esta herramienta se desarrolló tomando en cuenta las guías de accesibilidad para el contenido web, (Web Content Accessibility Guidelines) WCAG 2.0. Además, presentamos los resultados de la validación del prototipo de EvA-Web en donde se evaluó un sitio web y se identificaron barreras a la accesibilidad. La herramienta EvA-Web es uno de los productos generados de una tesis realizada por una estudiante de la licenciatura en Ciencias de la Computación que se ofrece en la Universidad de Sonora.

The Web

The focus of much academic work on Web accessibility has been concerned with the lack of implementation of the Web Content Accessibility Guidelines. There seems, as yet, however, to have been little critical reflection on the Guidelines themselves — save perhaps some awareness of the heterogeneous nature of the Web, and the difficulties facing Web developers trying to ensure their work displays true to their intentions across a wide range of different browsers and devices, making use of continually evolving and contested code. Yet, as this paper highlights, the long drawn out process by which version 2.0 of the WCAG came into being hides many skeletons, including aspects of the process of developing standards that bear closer scrutiny, and reveal much when viewed through Latourian eyes. The findings of this paper suggest that the WCAG2.0 are almost irrelevant today — to the detriment of those for whom they were made — and that the process of creating them was at fault.

With the growth of e-services in the past two decades, the concept of web accessibility has been given attention to ensure that every individual can benefit from these services without any barriers. Web accessibility is considered one of the main factors that should be taken into consideration while developing webpages. Web Content Accessibility Guidelines 2.0 (WCAG 2.0) have been developed to guide web developers to ensure that web contents are accessible for all users, especially disabled users. Many automatic tools have been developed to check the compliance of websites with accessibility guidelines such as WCAG 2.0 and to help web developers and content creators with designing webpages without barriers for disabled people. Despite the popularity of accessibility evaluation tools in practice, there is no systematic way to compare the performance of web accessibility evaluators. This paper first presents two novel frameworks. The first one is proposed to compare the performance of web accessibility evaluation tools in detecting web accessibility issues based on WCAG 2.0. The second framework is utilized to evaluate webpages in meeting these guidelines. Six homepages of Saudi universities were chosen as case studies to substantiate the concept of the proposed frameworks. Furthermore, two popular web accessibility evaluators, Wave and SiteImprove, are selected to compare their performance. The outcomes of studies conducted using the first proposed framework showed that SiteImprove outperformed WAVE. According to the outcomes of the studies conducted, we can conclude that web administrators would benefit from the first framework in selecting an appropriate tool based on its performance to evaluate their websites based on accessibility criteria and guidelines. Moreover, the findings of the studies conducted using the second proposed framework showed that the homepage of Taibah University is more accessible than the homepages of other Saudi universities. Based on the findings of this study, the second framework can be used by web administrators and developers to measure the accessibility of their websites. This paper also discusses the most common accessibility issues reported by WAVE and SiteImprove.

The purpose of this study was to determine the conformance levels of government websites in Sub-Saharan Africa (SSA) to Web Content Accessibility Guidelines (WCAG) 2.0 and examine which macro factors influenced the accessibility these websites. The findings indicated that the majority of government websites in SSA still had a long way to go to become accessible based on the WCAG 2.0 standards. None of the 217 government websites examined adhered to all the WCAG 2.0 guidelines. Cross country analysis showed that there are three macro factors influencing e-government accessibility in SSA, namely Human Development Index (HDI), Corruption Perception Index (CPI), and percentage of the active population (15-64 years). Countries with high HDI levels and low CPI levels tend to have websites with fewer accessibility errors, while those for countries with high percentage of the active population have more accessibility errors.

Este artigo tem como objetivo apresentar etapas de uma pesquisa que estudou a relação entre uma técnica de avaliação de acessibilidade – a verificação de conformidade de sítios eletrônicos com o WCAG 2.0 – com as características do perfil do avaliador. Para este fim, preliminarmente foram feitos dois estudos exploratórios: primeiro com diferentes perfis de expertise de avaliadores e roteiro predeterminado e segundo com avaliador com alto nível de expertise e roteiro livre, sendo predefinida apenas a técnica a ser utilizada. Os estudos indicaram (1) a confirmação de uma alta relação de um perfil mais aderente aos conhecimentos sobre acessibilidade e tecnologias web com os resultados da avaliação e (2) a possibilidade de interpretações equivocadas da aplicação de uma técnica sem predefinição de todos os passos a serem seguidos. A partir disso, com roteiro predefinido a partir do documento WCAG-EM 1.0, foi feito um terceiro estudo, apenas com voluntários avaliadores com nível adequado de conhecimento e experiência relacionados à acessibilidade, recrutados por meio de questionário on-line. Dos 83 respondentes, houve 62 respostas válidas e 25 preencheram os critérios para serem considerados aptos à etapa de avaliação de acessibilidade. Dentre estes, nove voluntários realizaram avaliações individuais pela técnica estudada segundo roteiro predefinido, e os resultados foram comparados entre si. Houve muitas inconsistências de entendimento e na maneira de informar os problemas, destacando-se de forma significativa um dos avaliadores que teve melhor autoavaliação em relação aos demais. Os resultados confirmaram a importância do perfil do avaliador para a efetividade da técnica de verificação de conformidade.

The choice of an interface platform to develop mobile applications may have important implications to how accessible the resulting product can be for visually-disabled users. This paper aimed to analyze four platforms to develop native and web-hybrid mobile Android applications, and to verify the adequacy of their interface components to implement mobile applications, in order to identify the main accessibility problems that could be encountered by developers when using them, and the main strategies to overcome those issues. We built 5 prototypes of mobile applications with the aim of adhering as much as possible to accessibility recommendations. The applications were built using techniques of native applications developed with Android Studio with and without Web components and hybrid development using the frameworks Apache Cordova, Ionic and Appcelerator Titanium. We then performed an accessibility inspection of a sample of 30 Android interface components present in 5 prototypes of mobile applications, to verify their adequacy for working with screen readers. The results showed that the prototypes developed using web components were more compatible with accessibility criteria in the Web Content Accessibility Guidelines (WCAG 2.0) and with the screen reader TalkBack. The most frequent accessibility problems in native components occurred in tables, headings and multimedia elements. We conclude by showing initial evidence that webbased components in hybrid applications developed using webhybrid and native with embedded web components currently have better support for accessibility than applications with only native components.

Objective: The present study examined whether implementing recommendations of Web accessibility guidelines would have different effects on nondisabled users than on users with visual impairments. Background: The predominant approach for making Web sites accessible for users with disabilities is to apply accessibility guidelines. However, it has been hardly examined whether this approach has side effects for nondisabled users. A comparison of the effects on both user groups would contribute to a better understanding of possible advantages and drawbacks of applying accessibility guidelines. Method: Participants from two matched samples, comprising 55 participants with visual impairments and 55 without impairments, took part in a synchronous remote testing of a Web site. Each participant was randomly assigned to one of three Web sites, which differed in the level of accessibility (very low, low, and high) according to recommendations of the well-established Web Content Accessibility Guidelines 2.0 (WCAG 2.0). Performance (i.e., task completion rate and task completion time) and a range of subjective variables (i.e., perceived usability, positive affect, negative affect, perceived aesthetics, perceived workload, and user experience) were measured. Results: Higher conformance to Web accessibility guidelines resulted in increased performance and more positive user ratings (e.g., perceived usability or aesthetics) for both user groups. There was no interaction between user group and accessibility level. Conclusion: Higher conformance to WCAG 2.0 may result in benefits for nondisabled users and users with visual impairments alike. Application: Practitioners may use the present findings as a basis for deciding on whether and how to implement accessibility best.
