FAMAID: A TOOL FOR AIDING PEOPLE WITH DISABILITY

People with disabilities suffer from discrimination and obstacles that restrict them from participating in society on an equal basis with others every day. They are deprived of their rights to be included in ordinary school systems and even in the work market. In the process of raising awareness, facilitating dailyroutines, and developing guidance, the idea of assisting such people with handy tools/software arose and was implemented in the FamAid tool. FamAid offers people with hearing disability the opportunity to be engaged in the society through many facilities. In this work, we implemented a web application that serves as a community for people with disability who can use sign language to access the app. The app uses hand gesture recognition technique which is considered an active research field in Human-Computer Interaction technology to perform sign language translation to text. Afterwards, the text will be provided as input to the app where the output will be generated based on the request of the user. This research presents an application which is considered a gift for people with speaking and/or hearing disability as it makes their lives easier

DAEL framework: a new adaptive e-learning framework for students with dyslexia

This paper reports on an extensive study conducted on the existing frameworks and relevant theories that lead to a better understanding of the requirements of an e-learning tool for people with dyslexia. The DAEL framework has been developed with respect to four different dimensions: presentation, hypermediality, acceptability and accessibility, and user experience. However, there has been no research on the different types of dyslexia and the dyslexic user’s viewpoint as they affect application design. Therefore, in this paper a framework is proposed which would conform to the standards of acceptability and accessibility for dyslexic students. We hypothesise that an e-learning application, which will adopt itself according to individuals’ dyslexia types, will advantage the dyslexics’ individuals in their learning process

Assessment of Web Content Accessibility Levels in Spanish Official Online Education Environments

Diversity-based designing, or the goal of ensuring that web-based information is accessible to as many diverse users as possible, has received growing international acceptance in recent years, with many countries introducing legislation to enforce it. This paper analyses web content accessibility levels in Spanish education portals according to the international guidelines established by the World Wide Web Consortium (W3C) and the Web Accessibility Initiative (WAI). Additionally, it suggests the calculation of an inaccessibility rate as a tool for measuring the degree of non-compliance with WAI Guidelines 2.0 as well as illustrating the significant gap that separates people with disabilities from digital education environments (with a 7.77% average). A total of twenty-one educational web portals with two different web depth levels (42 sampling units) were assessed for this purpose using the automated analysis tool Web Accessibility Test 2.0 (TAW, for its initials in Spanish). The present study reveals a general trend towards non-compliance with the technical accessibility recommendations issued by the W3C-WAI group (97.62% of the websites examined present mistakes in Level A conformance). Furthermore, despite the increasingly high number of legal and regulatory measures about accessibility, their practical application still remains unsatisfactory. A greater level of involvement must be assumed in order to raise awareness and enhance training efforts towards accessibility in the context of collective Information and Communication Technologies (ICTs), since this represents not only a necessity but also an ethical, social, political and legal commitment to be assumed by society

HERRAMIENTA PARA ANÁLISIS DE LA LEGIBILIDAD LINGÜÍSTICA DE CONTENIDO WEB EN ESPAÑOL COMO APOYO A PROCESOS DE EVALUACIÓN DE ACCESIBILIDAD

El ejercicio de la comprensión lectora es una práctica cotidiana e imperativa de la configuración del mundo contemporáneo como parte de los aprendizajes autónomos, lo cual ha generado que la sociedad actual se caracterice por interpretar o producir textos y contenidos generalmente ubicados en sitios web. La legibilidad lingüística se puede considerar como una condición necesaria para que un texto se pueda leer y se facilite su comprensión. Por otro lado, la accesibilidad web es un concepto que hace referencia al conjunto de elementos que permiten a un usuario sin importar sus condiciones pueda acceder a los contenidos ofrecidos en la web. Cuando se realizan procesos de evaluación de accesibilidad es importante determinar el nivel de complegidad del contenido textual, para determinar si es necesario realizar cambios, entregar otras alternativas del texto o material complementario. Sin embargo, determinar esto no es un proceso sencillo y puede requerir del análisis del nivel de legibilidad de los textos. En este trabajo se propone una herramienta denominada Hohkma, que permite analizar contenido textual en español, para determinar su nivel de legibilidad utilizando los índices de Fernández Huerta y Flesch-Szigriszt. La herramienta entrega explicación de los resultados, estadísticas y recomendaciones, con un enfoque desde el punto de vista de la accesibilidad, con el objetivo de convertirse en una alternativa que apoye en procesos de evaluación orientados a lograr sitios web más accesibles

Bridging the Gap: An Exploration of Visual Design Criteria Found in the "Accessibility for Ontarians with Disabilities Act, 2005" (AODA)

Information and communication technology such as World Wide Web have gradually become implanted in every aspect of individuals life such as education and training, employment, government, health care, and more. Web provides valuable resources and information for web users including people with disabilities and help them tackle several tasks that would otherwise need much more effort to be done. Accordingly, web accessibility creates a guideline with the aim of making the content of each web page available for a wider range of people with disability, has reached a new level of importance. For this importance, the government of Ontario passed a law titled the Accessibility for Ontarians with Disabilities Act (AODA), 2005, in which all internet and digital services must comply with accessibility guideline by 2025. Several researchers show a gap between professional design work and technically driven accessibility design guidelines. One of the reasons for this gap is an absence of concern for visual design during the process of implementing accessibility guidelines. The aim of this paper is to bridge the existing gap between accessibility and visual design to improve the overall usability and functionality of the system. In order to achieve this, I first identify and explain the visual design related criteria of AODA guidelines, their requirements and their impact on accessibility design. Then I demonstrate my experiment with utilizing visual design elements through the implementation of visual design principles on two selected websites to create an accessible web page that is not only usable but also has an aesthetically appealing interface

A user experience framework for business intelligence dashboards : an appreciative inquiry study within an agile software development environment

In South Africa and globally, companies focusing on business optimisation and continuous improvement have embraced business intelligence for the purpose of decision-making as data are becoming more readily available. Companies recognise the need for, and importance of, user experience when interacting with the dashboards to assist users with decision-making and to enable users to take timely evidence-based actions. It is no longer sufficient only to support users in achieving their goals by employing basic usability principles; digital products need to provide an overall positive user experience to be considered successful. Numerous frameworks have been developed for the user experience of digital systems. However, with the literature emphasizing the importance of context, those user experience frameworks cannot be transferred to business intelligence. This dearth of evidence-based business intelligence specific user experience frameworks comprises the rationale for this study. The research methodology is comprised of mixed methods as this methodological paradigm aligns best with the pragmatist and appreciative inquiry research approach. The research design framework draws on the Affordance Theory, Logic Model and Agile software development approaches. The context of the study is that of software development in an agile environment in South Africa. The theoretical research contribution comprises of the validated conceptual literature-based framework for the user experience of business intelligence dashboards and the compilation and use of an original research design framework that was utilised to guide the research. This research study also has value for industry in that it has produced a novel validated practitioners’ framework that can be used in practice to identify user experience shortcomings and highlight opportunities for improvement.School of ComputingPh.

Web Content Management System and accessibility awareness: A comparative study of novice users and accessibility outcomes

Since its creation, the Web has progressively developed and become a vital source of information in every domain and for almost all people. It is crucial to guarantee that the information contained on the Web is available for everyone, especially for people with special needs. Removing accessibility barriers is fundamentally based on tools, skills and support of all contributors, particularly the content creators, to ensure information is navigable and usable in the context of the end users experience. Web Content Management Systems play a significant role in structuring, storing and provision content to the Web and have evolved to address the difficulties of manually coding web pages versus the convenience of manipulating their content without any programing skills. Web Content Management Systems have gradually evolved to contain features and functions that allow content authors to shape their content in ways that address web content accessibility expectations, though only if the content author knows how to use these features to maximum effect. This thesis explores such usage by participants deemed to be novices, in that they have limited technical skills in the context of web coding and have limited expose to Web Content Management Systems or the application/awareness of the Web Content Accessibility Guidelines (WCAG). This research places an emphasis on the outcome of these novice users when provided with some basic training and awareness raising of WCAG principles and the use of a modern Web Content Management System. This is explored in the literature as an area of some importance as organisations with significant web presence cannot simply tell their content authors to ‘oh, and make sure it is accessible’ and hope that the end product will somehow achieve that goal without an investment in some form of accessibility education. For web managers and developers in all public sector organisations. “Make sure that all content commissioners and authors are fully trained in the importance of accessible content, and in the means that are made available for them to achieve this . (p. 58) The purpose of this research was to explore to what level the use of accessible Web Content Management System and novice users’ training impacted accessibility outcomes. This study emerged from the widespread role that Web Content Management Systems play in terms of storing and managing web content and the growing usage of these systems by experts or novices at an organisational or personal level. Through a selection process, this study identified a Web Content Management System that had a number of accessibility features, developed some training and ‘awareness raising’ materials and then asked novice users across two groups to apply what they had learned in order to develop an accessible website. The goal of the study was to ascertain if the two groups performed differently according to the training and awareness raising materials they received, and if even basic accessibility outcomes were achievable with just a few hours of training and from what was essentially an accessibility ‘cold start’. The study used a mixed methods approach encompassing three research methods; experimental method, survey method and observational method, to compare qualitative and quantitative data obtained from ‘accessibility awareness’ and ‘accessibility unaware’ participant groups. Thirty university students participated in this research and received accessibility awareness raising sessions, with additional accessibility-related examples for the accessibility awareness group. All participants undertook pre and post-tests that were designed to collect data allowing the researcher to compare the learning performance before and after the participants’ awareness session. At the end of the awareness session, the participants of both groups completed a survey which was designed to provide further data on the participant’s perception of web use and experience, the concept of web accessibility, web content accessibility guidelines, the system used, and their opinion of the accessibility awareness session. Data collected from the survey, pre and post-tests and the recording provided a holistic set of data from which the primary and supporting research questions were addressed. The results of the research indicated that the accessibility awareness group demonstrated measurably better accessibility outcomes than the unawareness group; these results being attributed to the awareness training session, participants’ searching behaviour, time spent on tasks, and effort made to implement accessible features and complete the required tasks. The participants in both groups had some prior knowledge in the use of the Web but limited or no skills in HyperText Markup Language (HTML) or the use of a Web Content Management System. While performing tasks, the participants in the awareness group attempted to apply the accessibility concepts learnt during the training session and spent more time in searching those concepts on the Web in order to provide accessible web page content. Conversely, most of the participants in the unawareness group were concerned by the “look” of the web page, rather than focusing on actual accessible content; they only mimicked the exemplar website they have been provided as an ‘end product’, but did not explore the how and why of accessible content. All the participants at the end of this study were aware of the significance of web accessibility and were favourable to consider it in any future website development they may be involved in. The outcome of the study shows that the use of accessible Web Content Management System with example-based accessibility awareness sessions can lead to improved accessibility outcomes for novice web content authors. This research strongly suggests that even small, focussed and example-based training/awareness raising session can drive an accessibility mindset in web content authors, even those with limited or no technical, accessibility or web authoring experience

Understanding accessibility problems of blind users on the web

The web is an eminently visual medium. However, not everyone accesses web content visually. Research shows that using the web is challenging for blind users. To create a good user experience for blind users on the web, we need a comprehensive understanding of the users’ problems. Currently, there is little knowledge about the problem differences between blind and sighted users, which makes it difficult to suggest and test design solutions that address these problems. This research aims to provide a further understanding of the problems blind users have on the web by comparing and contrasting problems between blind and sighted users and testing how design solutions to prevalent problems benefit blind users’ experience. The first study draws together the research literature into a common unified definition of web accessibility that was used to operationalise studies. The second study compared which verbal protocol (concurrent or retrospective) is better in user-based studies. The results showed that retrospective verbal protocol is a better option for eliciting problems on the web for blind and sighted users. Then, an empirical study compared the problems between blind and sighted users on the web. The results showed that the problems the two user groups encounter largely differ. There are specific problem types distinct to blind users, but also the characteristics of the problem types that had instances by both user groups were very different. Moreover, many problems blind users encounter were in relation to the search and browse features of the websites. A further investigation by two studies with blind users of how specific design solutions to prevalent problems users had (poor page structure, lack of feedback and excessive effort) in this specific design aspect showed that simple design solutions improve specific aspects of users’ experience. Although, for major improvements in the overall user experience a combination of design solutions is needed
