The Accessibility Imperative is the first publication offering a comprehensive overview of the many implications of the dispositions of the United Nations Convention on the Rights of Persons with Disabilities for ICTs (Information and Communication Technologies) adopted by the General Assembly on December 13, 2006 and signed by 118 states as of October 29, 2007. A milestone in documenting the multiple facets of the ever-increasing global challenges of ICT accessibility for persons living with disabilities, The Accessibility Imperative will serve as the foundation of the ongoing global dialogue established by G3ict - the Global Initiative for Inclusive ICTs - among multiple stakeholders to explore how to best implement the dispositions of the Convention on the Rights of Persons with Disabilities. The book includes a compendium of case studies of advanced assistive and accessible ICT solutions from around the world and the full text of the Convention.
