Accessibility Perspectives

Promote Awareness

"Web Accessibility: Essential for some, useful for all" is a compilation of 10 videos. Each section shows a specific aspect of accessibility and how it impacts users with and without disabilities. For links to individual videos and more information on each topic, please see web accessibility perspectives on the WIA website.

Color Blindness

Promote Awareness

We use color to convey content and information, but what if you couldn't see color or distinguish between the different colors on the screen? How would you perceive the information?

Try It

The image below has been altered using the Coblis tool to simulate a type of red-green color vision deficiency called Protanopia.

Alternate Text

Promote Awareness

When users cannot perceive visual information, they may rely on a screen reader. Screen readers convey information that cannot always be seen, such as alternative text for images. Screen readers also provide the user with information about how to navigate the information and what type of information is being conveyed such as images and links.

Try It

Since screen readers are tricky to use, we have set up an alternative way for you to experience this tool and the implications for its use. Click the image to open a dialog box containing the alternative text description.

Alt. Text 1

Alt. Text 2

Alt. Text 3

Click the eye to reveal the image. Which image had the most helpful alternative text?

Text to Speech

Promote Awareness

Many users, with and without disabilities, rely on text-to-speech tools. In addition to helping those with visual disabilities and dyslexia, they help struggling readers, multi-language learners, and many others. Text-to-speech tools can also help users when the color contrast is too low or the text is otherwise hard to read.

Try It

Test out accessing content through a screen reader by viewing or listening to the text below, from W3C Stories of Web Users. Click on the text below to hear it read aloud.

Stefan is a student who has dyslexia and attention deficit hyperactivity disorder (ADHD). Stefan finds it hard to maintain focus on his schoolwork, especially when reading a lot of dense text or following written instructions.

He likes digital textbooks and websites that allow him to use text-to-speech software because he can follow both the written and auditory words.

It’s important though that websites and other digital technology use plain language, a consistent layout, and don’t display pop-up ads or moving images, which are very distracting and confusing. Mobile apps and websites are often less cluttered and easier to use.

Captions

Promote Awareness

Captions (called “subtitles” in some areas) provide content to people who are Deaf and hard-of-hearing. Captions are a text version of the speech and non-speech audio information needed to understand the content. They are synchronized with the audio and are usually shown in a media player when users turn them on.

Try It
  1. Watch the video below with the sound off. See if you can figure out what is happening. Is the visual content enough to convey the message?
  2. Watch the video again. Leave the sound off, but turn the captions on. Are you able to consume the content information now?

Notes

This course was originally designed in Canvas with the Cidilabs Design Plus tool. Since I cannot provide you access to that course, I recreated a demo version to share with prospective clients and employers. The version here is meant to replicate the original as closely as possible. Still, there are some key differences, mostly related to the aspect ratio of the pages and differences in the tools available.
