“…The main goal in Plessers et al [21] is to generate the annotations for visually impaired users automatically from the explicit conceptual knowledge existing during the design process. The approach integrates the Dante [31] annotation process into the Web Site Design Method (WSDM) [9] that allows Web applications to be developed in a systematic way.…”

Engineering Accessible Web Applications. An Aspect-Oriented Approach

The development of accessible Web software is complicated for several reasons. Though some of them are technological, the majority are related with the need to compose different and, many times, unrelated design concerns which may be functional as in the case of most of the specific application's requirements, or non-functional such as Accessibility itself. In this paper, we present a novel approach to conceive, design and develop Accessible Web applications in an aspect-oriented manner. In order to reach our goal, we provide some modeling techniques that we specifically developed for handling the nonfunctional, generic and crosscutting characteristics of the Accessibility concerns. Specifically, we have enriched User Interaction Diagrams with integration points, which are used to reason and document Accessibility for activity modeling during user interface design. Then by instantiating a Softgoal Interdependency Graph template with association tables, we work on an abstract interface model (composed by ontology widgets) to obtain a concrete and accessible interface model for the Web application being developed. We use a real application example to illustrate our ideas and point out the advantages of a clear separation of concerns throughout the development life-cycle.

“…Some studies have been found that propose the application of WCAG to Semantic Web technologies such as ontologies, XML, XMLSchema and OWL [29,30]. Among the relevant studies found in the area of Web engineering methods, some propose the use of patterns on a method to include certain accessibility requirements in user interfaces [31] and others focus on a user-friendly approach that uses well-designed access patterns to provide efficient access in the navigation and retrieval of information for a website [32].…”

“…Thus, none of the previous approaches fully satisfy the accessibility standards. However, one interesting attempt meriting particular mention is the Dante approach, integrating the Web Authoring for Accessibility (WAfA) ontology [33,34] for the visually impaired into the WSDM method [30]. In this study, the Accessibility Web Applications (AWA) approach has been adopted.…”

Accessibility User interface development method Model driven development User Interface Description LanguageIt is a legal requirement in many countries to ensure accessibility for Web applications. Although there are numerous regulations and standards regarding accessibility in the de-velopment of user interfaces, accessibility is nevertheless quite difficult to achieve, let alone to maintain at a high level of quality throughout the development process. This difficulty is due to diverse factors including, but not limited to, the lack of proper development meth-ods, authoring tools and accessibility training for user interface development professionals. In an attempt to offer a solution to these difficulties, this paper proposes a methodological approach for the integration of accessibility requirements into a user interface develop-ment method based on User Interface Description Language (UIDL) or, more specifically, on the USer Interface eXtensible Markup Language (UsiXML) framework. The proposed strat-egy involves the integration of accessibility requirements into design primitives of the user interface development method. This paper focuses on accessibility requirements related to navigation in the Task Model, Abstract User Interface Model and Transformation Model. The application of the approach shown for the SPA4USXML tool also includes a proof of concept and validation of the proposal. The study shows that accessibility requirements included at the design stage in the modelling of user interfaces can be systematized through mech-anisms such as new transformation rules and the use of support tools such as SPA4USXML.

“…In combination with the Web Site Design Method (WSDM) [1] it is possible to fully automate the generation of semantical annotations used for Dante [15]. It is approximated that 85% of the annotations can be provided that way.…”
