When I worked at W3C/WAI, among other things, I learned a lot of acronyms. Like, there’s WAI-ARIA, Techniques, Understanding Documents, specific guidance for people with cognitive disabilities, the WCAG standard, soon to be superseded by WCAG 2.1, with WCAG 3.0 also kind of coming up, but still in the works. WCAG has levels, there is also ATAG, which is about authoring tools, like CMSes, there’s testing tools like Axe, specific guidance about low vision. There’s a lot to know about assitstive tech and accessible VR. Actually there is a great doc abbreviated to XAUR that has lots of useful info for VR devs to think about when they want to make accessible experiences. There’s UAAG, for browsers, ACT, again, a maturity model for organisations that do accesssibility and want to professionalise their practice, WebVTT, a standard for subtitling and things like that, AGWG, the working group that makes the accessibility guidelines, lots of laws and policies, semantics is a whole talk in itself, conformance evaluation matters and with EARL you get an interoperable data format, authoring practices are a thing for ARIA, WCAG-EM is an evaluation method and then accessibility statements are increasingly important.
I know, it’s a lot… so I get why people would feel lost when they think about accessibility. Sorry for the tangent.
