ABSTRACT Due to the extensive amount of information regarding web accessibility developed in recent years, developers find difficulties
for creating accessible web applications. Accessibility knowledge management tools can facilitate this task. However, existing
tools do not provide enough support to all the activities of the development process. In this sense, developers have to use
diverse tools focused on different stages and they are also required to search for accessibility information from different
sources. The aim of this paper is to present a framework for managing accessibility guidelines. It serves as a central repository
where developers can search for accessibility guidelines, define new guidelines, and share them with other developers and
evaluating them automatically. Therefore, this framework facilitates developers’ tasks as it gives support to several activities
of different stages throughout the development process.

    ABSTRACT: This paper describes the development of a web accessibility knowledge management tool, known as the Accessibility Evaluation Assistant (AEA), designed to assist novice auditors in the process of an accessibility evaluation. The tool is designed primarily for undergraduate and postgraduate computing students with limited knowledge of web accessibility, limited opportunity to study accessibility and limited access to expert reviewers or disabled user groups. The software supports the novice auditor through a series of tailored checks based on a specified user groups, or the specific content features of the website. This process enables the novice auditor to draw more accurate conclusions about the accessibility of individual web sites, and facilitates effective prioritization when conducting fixes.

    ABSTRACT: This paper presents an approach of user interface adaptation based on context awareness system and context modeling in order to ensure accessibility for disabled people in pervasive environment. The challenge is how to design and generate accessible software systems that accommodate dynamically to changing context.

    ABSTRACT: The Accessibility Evaluation Assistant (AEA) is a web accessibility knowledge management tool designed specifically to assist novice auditors in conducting an accessibility evaluation. The software incorporates a bespoke structured walkthrough approach designed to guide the auditor through a series of checks based on established accessibility principles with the goal of identifying accessibility barriers. A previous trial examined the effectiveness of the AEA and explored the pedagogical potential of the tool when incorporated into the undergraduate computing curriculum. The results of the evaluations carried out by the novices yielded promising levels of validity and reliability. This paper presents the results of a second experiment designed to test the overall efficacy of the AEA when compared to a WCAG 2.0 conformance review. The results of evaluations produced using both AEA and Conformance Review methods were examined and comparisons made of quality factors such as effectiveness, reliability, efficiency and usefulness. Quantitative and qualitative data from the experiment support continued use of the AEA in an educational context, highlighting the benefits compared to WCAG 2.0 and gives further insight into the complex nature of developing accessibility evaluation skills in novices.
