Abstract: IncluSite is a novel approach to providing web content accessibility as a service. IncluSite automatically inserts code into web pages requested by Internet users to adapt it to web accessibility standards and to add advanced user interfaces right into the web content being served to Internet users. IncluSite allows users with physical or psychical disabilities to navigate web sites in the most suitable way according to their needs, and without the need of specific hardware or software. IncluSite's technical approach also allows web site owners to automatically adapt web contents without changing the original web pages: including a link to IncluSite is sufficient.
