Developing Advanced Accessibility Conformance Tools for the Ubiquitous Web

AbstractThis paper presents our perspectives on the key challenges developing accessibility conformance tools. These challenges are influ- enced by the rapid evolution of the web ecosystem composed by web technologies (e.g., HTML5, CSS3, JavaScript), user agents (e.g., web browsers) and devices (e.g., smart phones, tablets, televisions), and by the usage of the aforementioned technologies by users with different requirements, preferences and context of use. We introduce these challenges from a tool developer perspective and present attempts to face such problems in a real development environment for a commercial tool. We describe as well related work from different EU-funded research projects and how such knowledge is fed to the imergo® Web Compliance Suite.
