The purpose of this combined glossary is to allow comparison of definitions, and potentially to provide a single glossary for all the accessibility guidelines. The various WAI working groups and individual readers of more than one guideline will benefit from a consistent use of terms.
WCAG.com is your essential online resource for understanding and applying the Web Content Accessibility Guidelines (WCAG), advancing web accessibility and improving your users’ experience.
Describes how the Web Content Accessibility Guidelines (WCAG) can be applied to non-web information and communications technologies (ICT), including documents and software.
The European accessibility act is a directive that aims to improve the functioning of the internal market for accessible products and services, by removing barriers created by divergent rules in Member States.
The U.S. Access Board is a federal agency that promotes equality for people with disabilities through leadership in accessible design and the development of accessibility guidelines and standards for the built environment, transportation, communication, medical diagnostic equipment, and information technology.
The Access Board is responsible for providing technical assistance and training on these Standards.
Accessible Rich Internet Applications (ARIA) is a set of roles and attributes that define ways to make web content and web applications (especially those developed with JavaScript) more accessible to people with disabilities.

Hey everybody! Josh here with Online ADA
and in this video we're gonna cover WCAG
article 1.1.1 of the WCAG
accessibility guidelines. So what is WCAG 1.1.1?
This is the alt text. It says non text content
this is for level A compliance
the actual documentation for this article reads
"All non text content that is presented to the
user
has a text alternative that serves the equivalent
purpose,
except for situations listed below.
Controls and input.
If non text content is a control or accepts user
input and it has a name that describes his
purpose". This is in reference to form inputs,
buttons on forms,
first name, last name, email address. All of those
forms.
Those are gonna be
inputs that require
something from the user and they need to have
labels and they need to have instructions
that would comply with
the alt text requirement.
Time based media. These are gonna be things like
your
videos or audio tracks or animations,
even carousels.
Things that are playing that
are animated or moving that a non visual user
may have difficulty with
when they visit your site. They need to have some
sort of
text alternative.
Let's read that one.
If non text content is time based media, then text
alternatives at least provide descriptive
identification of the non text content.
Now this is saying
that you don't necessarily have to have a text
dictation of everything that's happening on that
screen or in that
animated element,
but you have to have a descriptive identification
of it
so,
you know they are tabbing through with their
screen reader they come across that maybe isn't
explaining everything that's happening in the
animation
but it's going to say this is an animation of
'insert
description here'.
Test.
Test is literally what it sounds like if you are
taking, like for a college exam
or some sort of school related activity,
Test is going to be an actual test that happens
on the website.
So if non text content is a test or exercise that
would be invalid if presented in text,
than text alternatives at least provide
descriptive identification of the non text
content.
Most tests that you have on a website are probably
gonna be like the radio buttons yes/no,
a) b) c) d),
something like that. So that is text content.
This would be a situation where
the test was presented in maybe like a video
format or if there was,
I can think of,
software that might be teaching you how to speak
Spanish or something and you have to
speak into a microphone. That would be sort of
the situation where
you actually start to have a description of what
is required for a non visual user.
Sensory.
I personally have not ever run into this one
myself but it reads, "If non text content is
primarily intended to create a specific sensory
experience, than text alternatives at least
provide descriptive identification of the non
text content". Same story,
you have
that can't really be dictated or described
perfectly you have to just give a description of
an overview of what the content is to the user.
CAPTCHA.
This one happens all the time.
Forms have these, you know anytime you have to
sign up for newsletter.
These are for avoiding spam and they are to
make sure that you are a human
that is submitting the form and not a robot or a spammer.
It reads,
"If the purpose of non text content is to confirm
the content is being accessed by a person rather
than a computer,
than text alternatives that identify and describe
the purpose of the non text content
are provided
and alternative forms of CAPTCHA using output
modes for different types of sensory perception
are provided to accommodate different
disabilities".
Now that's a big one.
I run into a lot of times on a forms where you
only have like a check box
or you have something where you have to pick all
the storefronts out of a bunch of like a grid of
squares.
Those are great
and they definitely provide their
purpose to visual users, but somebody who's hard
of seeing may have difficulty seeing those
storefronts in the pictures. So
this is saying that we need to have some way of
switching that over to like an audio
test.
Or from the
checking the store fronts to a check box or
something like that. Some alternative
that is text based that a non visual user can use
as well.
The next one and the last one on this list is decoration,
formatting,
invisible.
"If non text content is pure decoration,
is used only for visual formatting...
What to expect from the WCAG 3.0 (Web Content Accessibility
First Published as part of European Accessibility Leadership Review, March 2020Version 3.0 of the Web Content Accessibility Guidelines (WCAG) are due for publication but what can you expect and how
W3C Accessibility Guidelines (WCAG) 3.0 will provide a wide range of recommendations for making web content more accessible to users with disabilities. Following these guidelines will address many of the needs of users with blindness, low vision and other vision impairments; deafness and hearing loss; limited movement and dexterity; speech disabilities; sensory disorders; cognitive and learning disabilities; and combinations of these. These guidelines address accessibility of web content on desktops, laptops, tablets, mobile devices, wearable devices, and other web of things devices. The guidelines apply to various types of web content including static, dynamic, interactive, and streaming content; visual and auditory media; virtual and augmented reality; and alternative access presentation and control. These guidelines also address related web tools such as user agents (browsers and assistive technologies), content management systems, authoring tools, and testing tools.
