Videoconferencing

Real-time audio-and-video communication between two or more people over a network, typically mediated by a software platform such as Zoom, Microsoft Teams, Google Meet, WhatsApp, or WeChat. Videoconferencing is a significant accessibility touchpoint: it can lower barriers for disabled people by removing travel and offering multimodal channels (video, audio, chat, captions, screen-share), while also creating new barriers around caption quality, sign-language interpretation space, interface complexity, and fullscreen takeovers that hide the external memory aids disabled users rely on. Accessibility-relevant concerns include keyboard and screen-reader operability of host controls, quality of live captions and auto-translate, support for pinning interpreter video, and tolerance of paper-based or off-screen workflows.
