Event accessibility

From the Hybrid Events Wiki, published by Magnetize ME

Event accessibility is the practice of making events usable by people with disabilities. More than one in four U.S. adults has some type of disability,[1] about 15% of American adults report some trouble hearing,[2] and the World Health Organization estimates that 430 million people worldwide need rehabilitation for disabling hearing loss.[3] Hybrid and virtual events add online requirements, such as live captions and accessible platforms, to the physical accessibility of a venue.[4]

Title III of the Americans with Disabilities Act covers businesses open to the public, such as hotels and theaters, and requires them to communicate with people with disabilities as effectively as with others, which may require aids such as sign language interpreters.[5] The Department of Justice lists real-time captioning, CART, qualified interpreters and video remote interpreting among these aids.[8] Its web guidance applies the ADA to web content, calls the WCAG guidelines helpful, and says videos should have accurate, synchronized captions.[9]

A 2024 Justice Department rule adopted WCAG 2.1 Level AA as the standard for state and local government websites and apps, with compliance dates later extended to 2027 and 2028.[10] Section 508 of the Rehabilitation Act requires federal agencies to make the technology they develop, buy and use accessible,[6] and the U.S. Access Board's standards incorporate WCAG 2.0 Level A and AA.[11]

Captions

Under WCAG, captions are required at Level A for prerecorded video and at Level AA for live video (success criterion 1.2.4); they serve deaf and hard-of-hearing people and people who process written information better than audio.[12][7] Level AA also calls for audio description, narration that conveys important visual information, for prerecorded video.[13]

Live captions are usually produced by professional real-time captioners, known as CART (Communication Access Realtime Translation) providers, who can work remotely; the W3C says automatic captions are not sufficient unless confirmed to be fully accurate, since an error such as a dropped "not" can change the meaning.[12] Section508.gov says automatic captions do not yet meet the minimum standard for prerecorded media.[14] A study of 11 speech recognition services on university lectures found an average English word error rate of about 7%, ranging from 2.9% to 20.1%, with live recognition less accurate than processing a recording afterward.[15] New York State advises that automatic captions should never replace CART when CART has been requested.[16]

Sign language interpretation

Interpreters can be streamed in a video window, and the W3C recommends that platforms let users pin sign language participants in consistent positions on screen.[4] On Zoom, hosts can "spotlight" an interpreter so the video is pinned for everyone,[17] and in webinars the interpreter must be a panelist so they stay visible.[18] UCSF notes that cloud recordings may not include interpreter video and that captioners and interpreters must be assigned to the same breakout rooms as the attendees who requested them.[19] The DOJ requires video remote interpreting to show a sharp, large image of the interpreter's face, arms, hands and fingers without lag.[8]

Accessible materials

The W3C advises sending slides and handouts to participants, interpreters and captioners before an event in formats they can adapt, not only as PDFs, and verbally describing slides and visual activity such as a show of hands.[20] Materials should be shared as files rather than only by screen sharing, because shared screens send images that screen readers cannot read.[4] Captioners also benefit from receiving names, technical terms and slides in advance.[19]

Accessible platforms

The W3C recommends that organizations buying a meeting platform require its interface to meet WCAG 2.1 Level AA and review the vendor's accessibility conformance report, and that hosts disable waiting rooms so participants who drop out can rejoin easily. When human captioning is not provided, any participant should be able to turn on automatic captions without the organizer's approval.[4]
