Annex I requires that information, user interfaces, and supporting features be accessible so disabled users can perceive, operate, understand, and benefit from the offering. For products, that can reach the product itself, packaging information, instructions, and interfaces. For services, it reaches the information about the service and the digital channels through which the service is delivered.
The local grounding pack also shows that specific categories receive more detailed functional requirements. For example, e-readers are expected to provide text to speech technology, communications services require alternatives to voice only interaction and synchronised emergency communications features where applicable, and media access services must preserve accessibility components such as subtitles and audio description.
