ABOUT THE WORKSHOP

Following up the tradition established in the last two years, this workshop is aimed at bringing together professionals and researchers interested in discussing recent trends and perspectives in Web usability and accessibility. Its main purpose is to assess the effectiveness of existing approaches for Web usability and accessibility evaluation (review guidelines, usability models, usability evaluation methods, usability checkers, accessibility verifiers, logging tools, automatic metric capture tools, statistical tools, etc.), with the final objective of allowing participants to discuss and get to know the most innovative and advanced experiences in usability and accessibility for the Web.
One of the goals of this year's edition will be to discuss the impact of these issues in modern Web applications, commonly referred to as Web 2.0 applications. The current trend in the creation of such applications clearly points toward a high user involvement in the creation of contents, annotations, and evaluations. Web sites like MySpace, YouTube, or Wikipedia are living an indisputable success. Another practice that is currently gaining popularity, even among users with only little programming skills, is the development of online applications, called mashups, which start from contents and functions that are provided by third parties that open their APIs toward developers and end users. These so-called social applications prove the initially unexpected value of integrating end users in the creation process of online applications. However, while several efforts have been so far devoted to the production of authoring environments and development tools, and to their enabling technologies, there is a lack of proposals for the definition of usability/accessibility principles and evaluation methods.
The workshop will therefore contribute to clarify several concerns, such as:
  • What are the shortcomings of existing approaches for Web usability and accessibility evaluation?
  • Are current approaches adequate with respect to the new challenges posed by modern Web 2.0 applications?
  • How can the Web application usability be decomposed into a set of measurable attributes? For example, the ISO 9126 standard decomposes usability into five sub-characteristics. The standard does not specify how these sub-characteristics can be effectively and efficiently measured.
  • What is the suitability of existing UEMs to evaluate Web interfaces?
  • What are the specific usability criteria for Web artifacts? To which extent do they depend on the family of applications (application domain) under consideration? Does the new family of Web 2.0 applications require ad hoc criteria?
  • How can we broaden accessibility evaluation to involve people with disabilities? Is it possible to provide a more effective solution than merely conforming to accessibility standards?
  • What are the strengths and weaknesses of tools for automated evaluation? For example, many accessibility tools are based on accessibility guidelines, but vary in their interpretation of guidelines. So these results still require human judgment. More interestingly, are such tools suitable for the evaluation of the so-called Rich Interfaces that characterize the modern Web scenario?
  • How can the usability and accessibility of Rich Internet Applications, mashups, community portals, or any other class of Web 2.0 applications be assessed?
