Anotation

This document provides an introduction to and basic guidance on augmentative and alternative communication (AAC) in the information and communication technology (ICT) domain. It also provides common definitions and a framework for the development of further, more detailed guidance relating to aspects of these AACs. This document recognizes that AAC can be delivered on various ICT devices and the importance of consistency for users across devices. It applies to AAC software and not the devices on which the software is used. This document recognizes that AAC provides many users with a unique form of communication that is not necessarily based on any specific natural language.
