8th International Cross-Disciplinary Conference on Web Accessibility

Crowdsourcing the Cloud: An Inclusive Web by All and For All?

Co-Located with the Twentieth International World Wide Web Conference, in Hyderabad, India.


Cloud-computing is the technological paradigm where computing resources are distributed over the Internet. This way, the browser becomes the interface to access services and applications with almost unlimited storage capacity and processing power. Cloud-computing and the applications deployed over it facilitate collective intelligence and crowdsourcing phenomena, where millions of users can contribute to a common goal. Following these approaches, a number of successful projects that focus on web accessibility have been released in recent years. These developments range from platforms to collectively removing accessibility barriers to making assistive technologies widespread and available for all. These preliminary approaches such as online screen-readers and accessibility repairing applications have yielded promising results towards an inclusive web by removing both economical and accessibility barriers. In order to develop the cloud to its full potential as far as accessibility is concerned, there are still several research questions that should address the weak points and challenges in a timely manner in order to create an inclusive Web.

Mirri, Silvia and Salomoni, Paola and Prandi, Catia; for Augment browsing and standard profiling for enhancing web accessibility

The opportunity of effectively tailoring Web resources presentation - depending on each single user needs and preferences - represents a challenge and a necessity for accessibility and inclusion. On the Web, customizing means transcoding content according to some user and/or device (contextual) settings. Such a profiling refers to devices constraints, user habits, skills, different needs (or tastes) about interaction, in order to drive all the necessary procedures for content (re)shaping. The usual set up that users provide for assistive tools such as screen readers or speech-to-text applications, is a common practice (and a typical example) for a subjective, better enjoyment of resources.

This work describes an augment browsing system, which allows users to set up their needs and preferences about Web pages presentation from the browser interface and is capable to automatically modify (transcode) content, according to such settings at client-side. The system is based on a widespread Web browser extension (GreaseMonkey) and well-known standards have been utilized to represent user's settings. Finally a case-study of the system has been assessed on a widespread social network, also taking into account some evaluations about accessibility by a group of blind persons.

2011 John M Slatin Award for Best Communication Paper

Thiessen, Peter; for WAI-ARIA live regions and HTML5

The W3C Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) and HTML5 are exciting and relatively new specifications with many new semantics that together help describe the complex desktop like behavior found in many Web applications. One aspect of ARIA, Live Regions, define markup that an Assistive Technology can use to understand how to treat a Document Object Model (DOM) update. Past work has been done showing live regions effectively expose DOM updates. However, little testing has been done on the combination of HTML5 elements with live region attributes. Test cases as well as the results of the test cases and vendor support are discussed in this paper.
