The Accessible Platform Architectures Working Group has published a First Public Working Draft of XR Accessibility User Requirements. This document lists user needs and requirements for people with disabilities when using virtual reality or immersive environments, augmented or mixed reality and other related technologies (XR). This document is most explicitly not a collection of baseline requirements. It is also important to note that some of the requirements may be implemented at a system or platform level, and some may be authoring requirements.
