A11y 101: 1.2.6 Sign Language (Pre-recorded)

A11y 101: 1.2.6 Sign Language (Pre-recorded)

Published on December 16, 2024

This week we meet our first AAA level success criterion. This put me in a pinch. I had to decide if I wanted this series to include all criteria. Alternatively, it just includes the ones needed to get conformance to current legal standards. And I’m coming out in between. I’ve decided to include only the AAA that should be covered in my opinion.

So this week we’ll look at the needs around Sign Language. We’re still discussing video, but we’re back at pre-recorded video. I will say, if you are holding a webinar, you should have a live sign language interpreter.

A11y 101: WCAG 1.2.5 Audio Description (Prerecorded)

A11y 101: WCAG 1.2.5 Audio Description (Prerecorded)

Published on December 9, 2024

This week we’re still talking about video. They say a picture can say one thousand words. Video is thousands of images that tells us more than what the audio alone says. Most video on the web these days is between 24 and 30 frames per second. That potentially would put a one minute video at roughly 1.8 million words. Even if 30 frames equal one picture, you are still responsible for up to 60,000 words. How do we do this?

A11y 101: WCAG 1.2.2 Captions (Prerecorded)

A11y 101: WCAG 1.2.2 Captions (Prerecorded)

Published on November 18, 2024

We’re still working with video and audio in 1.2.2. I’ve mentioned captions in the previous A11y 101 posts. Success Criterion 1.2.2 lays out the specifics for captions.

Simply put, if there is video with speaking you need captions. Did you provide an audio description? Those get added to the captions.

Caption Styles

There are two basic ways to provide captions, open and closed. In either case, you need to have someone transcribe the audio. They need to include the time when the display of the text starts.

Open Captions

Open captions are the minimum support you should provide. Open captions are “printed” into the video. They are baked in and designed to fit the design aesthetic of the video.

Why do I call this minimal? Well the user lacks control to customize it. Additionally, this only supports deaf and hard-of-hearing folks. Our next version offers more features.

Closed Captions

Since open captions are part of the video, they can actually create problems. The most problematic is that they may move around the screen depending on what the video needs. This makes it hard for users, especially low-vision users, to keep track and find them.

Closed captions provide and answer to this. Closed captions are a separate file called in the <video> element. Usually it is a .VTT file. It’s pretty simple to build. I have an article on a11yproject.com that I published in 2013 that explains how to do it.

The next thing that closed captions bring – screen reader and Braille display support. Closed captions are considered real text on the page for screen readers. Now the Blind-Deaf can get the story too. The low-vision user can lean back on the screen reader to help. It also helps with SEO.

A11y 101: WCAG 1.2.1 Audio-only and Video-only (Prerecorded)

Published on November 11, 2024

I discussed non-text content last week and mentioned video. WCAG decided to be specific when addressing items that fall under the bigger 1.1.1 criteria.

In success criteria 1.2.1, we’re informed we need to provide one of two options, unless the audio or video IS the alternative. Let’s look at our options:

  • Prerecorded Audio-only: An alternative for time-based media is provided that presents equivalent information for prerecorded audio-only content.
  • Prerecorded Video-only: Either an alternative for time-based media or an audio track is provided that presents equivalent information for prerecorded video-only content.
https://www.w3.org/WAI/WCAG22/quickref/#audio-only-and-video-only-prerecorded

OK, what are our key words? “Time-based media” is mentioned in both. We see in three places, this is about pre-recorded media and not live. This means we can use the edited audio or video. We can then give it to someone to create a transcript. They can also make closed captions for videos.

Once returned, we offer a link to the transcript. This can be an accessible PDF, but it is often easier to to make it HTML. The transcript doesn’t need to live on another page. The preferred method is to use a disclosure next to or below the media. When closed the content is hidden. The user who needs it, can expand the transcript to read.

If we are working with video, does it have an audio track that describes everything in the video? This is usually an audio description track. It’s provided in addition to the regular audio track. It will describe what is happening without needing to see. One of my favorite examples is a Frozen trailer:

Transcripts are easy. There are many ways to get them done, and some are super cheap. But before you ever put the transcripts on your site, have someone, better yet several, proof them.

Designing with Empathy

Designing with Empathy

Published on October 7, 2015

This weekend I had the pleasure of speaking at the inaugural edition of Open Source & Feelings. It was an amazing conference tackling some really hard topics. I received really great feedback from the audience on my “Designing with Empathy” talk and several asked for the transcript as they couldn’t take notes fast enough. So here is the talk broken out with what was on the slides as well as the script I tried to follow. The video is coming, and I will add that when available.

When I first pitched this talk, I was thinking it was about accessibility because that’s usually what I speak about. As I wrote it. And rewrote it. And rewrote it. It evolved into being something bigger, higher level, and more important than just accessibility. It became about thinking of others and building experiences that we can all be proud of.

Trigger Warning

Some slides contain content that may trigger motion sickness

Some of my slides contain motion that could make you feel ill. I’ll give you a warning before they occur.

Empathetic design makes badass users.

Infinite Canvas 6 With Rachel Nabors

Infinite Canvas 6 With Rachel Nabors

Published on August 3, 2015

Last week I got to be on a podcast. This week I appear on a screencast with Rachel Nabors talking about vestibular disorders in general and how animation may affect a user on your site.

Rachel Nabors

If you don’t know who Rachel is, she is an amazing illustrator, cartoonist, speaker and animator using all those skills to shine a light on the web can be a better place with the right kinds and amounts of animation.

We had a lot of fun recording it, but I need to get a better microphone, sorry for the scratchiness that my beard brings. Also, we had a few problems trying to record it. Running Skype, Camtasia, Quicktime, and all the websites we looked at kept crashing our GPUs.

The screencast is on Youtube, and you should totally subscribe. She hasn’t done one in a while and it could be another while before we see another, so unlike the podcast episode I did, I’m embedding the video here.

Enjoy! Hit us up on Twitter with any questions you may think of.
