WAI-Dev, Web Accessibility Initiative (WAI) Ecosystem for Inclusive Design and Development, will develop strategies to support mainstream production of inclusive components and services; demonstrate the potential value and showcase good practice in inclusive design; and support enhanced policy strategies for consistent adoption and implementation of accessibility by public and private sector organisations.WAI-Dev will primarily target the Web as the essential technical platform and universal interface for information and communication technology (ICT) through which to address the accessibility of advanced technologies and delivery channels including those for mobile devices, portable computers, digital television, telephony, and more. It will build upon recent technical and policy advancements in accessibility and on the cross-cutting benefits of accessibility for everyone regardless of age, gender, software, hardware, connectivity, language, literacy, digital skills, social and economic situations, and physical and mental abilities. It will thereby facilitate more mainstream market adoption of accessible and inclusive design-for-all practices throughout the production chain, and support implementation of accessibility policies and targets set by the European Commission and EU Member States.WAI-Dev will result in:Support for industrial strategies for the production of inclusive components and services;Demonstration of the social and economic value and of good practice in inclusive design;Enhanced policy strategies that support the adoption and implementation of accessibility.WAI-Dev will be led by the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI), through its European host, European Research Consortium for Informatics and Mathematics (ERCIM). It will utilise the open W3C consensus process and mobilise participation from W3C Member organisations as well as from the public to develop authoritative resources with significant market impact.
