RTC Accessibility User Requirements (RAUR) is published as a Working Group Note. Real-time communication (RTC) provides real-time   peer to peer audio, video, and data exchange directly between supported   user agents. This enables instantaneous applications for video and audio   calls, text chat, file exchange, screen sharing, and gaming. RAUR describes various accessibility related user needs,   requirements, and scenarios for real-time communication (RTC)   applications. These user needs should drive accessibility requirements   in various related specifications and the overall architecture that   enables RTC.
