    Your weekly frequent11y newsletter, brought to you by @ChrisBAshton:

    A Deep Dive on Skipping to Content

    • Paul Ratcliffe describes a “2021-friendly” implementation of a skip link. It looks something like this (note that the text is hidden visually until it is focused – I’ve omitted this from the code below):
      • <a href="#skip-link-target">Skip to main content</a>
      • <a href="#skip-link-target" id="skip-link-target">Start of main content</a><main>the content</main>
    • Paul points out that the use of <main> markup means savvy screen reader users can skip straight to the main landmark. For those that rely on skip links instead, he recommends a link in the <header> which refers to a link just above the <main> (not inside it, as it would impact SEO).
    • I hadn’t seen an <a> element as the target of a skip link before; Paul says this is to give users feedback that the skip link worked. If the page content is too short, the browser wouldn’t scroll and it could be difficult to show that the focus has moved otherwise.
    • Susanna Celso left some comments for Paul before writing a follow-up blog post, arguing that the proposed implementation could confuse users (linking to a link that links to itself, and also stating that you’ve reached the “start of main content” when technically you’re still outside that landmark. Susanna makes the case for linking to the <main> element directly, though concedes screen readers will automatically start reading all of the text in that element, which can be an awkward experience.
    • Susanna concludes that the best link target would be a <h1>, provided it’s the first element inside the <main> landmark.
    • An interesting and healthy discussion between two clearly knowledgeable developers – worth reading both posts!

    Writing great alt text: Emotion matters

    • Jake Archibald describes how he was trying to decide what alt text to use for his avatar, which would appear alongside his name, in a list of conference speakers. His (and my) instinct was that it should be nullified (alt="") because it would otherwise be repeating information elsewhere in the page.
    • However, in his avatar, Jake is pulling a pose and aiming to inject a bit of humour. It’s not right that screen reader users miss out on that context. So Jake opted for the following alt text: “Jake, cheekily peering from behind a plant”.
    • Léonie Watson has written about this in her blog post, Text descriptions and emotion rich images. Context matters. Developers sometimes worry that descriptive alt text will make the page too ‘noisy’, but as Léonie points out, screen reader users will skip over large swathes of the page in the same way as sighted users would.
    • This seems to be a bit of a trending topic at the moment; I recently covered a similar article by Eric Bailey which concludes that most images nowadays are not purely ‘decorative’ and do require alt text.
    • Jake adds that “if you’re trying to do the right thing, you’re almost certainly improving the experience for real people”. Most of the time, your alt text won’t be worse than no alt text at all.

    Twitter’s new design to get fix after headache complaints

    • BBC article from 16th August. Highlights:
      • “Twitter is making changes to its new redesign, after users complained of headaches and discomfort.”
      • “Unveiled only last week, the redesign mainly involved high-contrast colours and a custom-designed font, Chirp.”
      • Its aim was to “improve content consumption and clean up ‘visual clutter’. But many, especially with accessibility needs, found it confusing, hard to read and uncomfortably bright.”
      • Users have reported the font being smaller and denser, so are having to strain their eyes more to read.
    • Twitter Accessibility have confirmed that fixes are on the way.

    It is time to ditch the title “Evangelist” from Accessibility

    • Ronise Nepomuceno explains why she hates the term ‘Accessibility Evangelist’:
      • It reinforces the idea that accessibility is a ‘nice to have’ that can be deprioritised
      • It has its roots in tech in the 1980’s, when Apple put together a team to ‘evangelise’ developers to develop for the Macintosh platform without the financial incentive compared with their competitor IBM. Ronise feels this is exploitative.
      • It has religious connotations: “they think we are coming for them, to judge for their sins and condemn them all to eternity in Hell”.
      • “It is also essential to respect the boundaries between Digital Accessibility and Disability Rights. They are two different things”.
      • Ronise points out that the term is applied in other parts of tech, e.g. “Cloud Evangelist”.

    What people should know BEFORE writing articles or creating products about accessibility

    • Sheri Byrne-Haber writes about getting disabled users involved in your product development early on. It is possible to build a product that is technically accessible but is inefficient and unusable in practice. “You cannot retrofit lived experience”.
    • Some products don’t support an intersectionality of disabilities. Sheri gives the example of an accessibility overlay that offered profiles for motion sensitivity, and for vision loss, but not for both at the same time.
    • Language is important when it comes to writing about accessibility. Terms that are out of favour include “suffering”, “wheelchair bound”, “high / low functioning”, stigmatizing the individuals being labelled and “conveying nothing about the strengths that individual might possess”.
    • Sheri bemoans the use of “headcounts” to make disability inclusion decisions. “How many people is this going to benefit?” is irrelevant; accessibility is a civil right.
    • Sheri ends with this: “Accessibility is a program, not a project”. If you work from a checklist, or are working to an end date, that is a warning sign.

    Tech platform devises new system to simplify process of booking rail travel for disabled travellers

    • Whoosh Media have created a system, “The Real-Time Journey Dashboard”, that allows you to scan QR codes on your train seat, to view information such as location of toilets on the train, as well as a live dashboard demonstrating journey progress and delays.
    • “Travelling by train is very often a hazardous lottery for wheelchair users and those with restricted mobility, simply because rail companies have failed to keep up with the way people research their journeys.”
    • The article above is light on details – I found more information at Onboard Hospitality:
      • Currently found on Northern Rail and Grand Central Rail, with more operators to follow in the coming months.
      • The system is currently receiving around 1500 scans per day.
      • The system can also be used to report antisocial behaviour to the British Transport Police.
      • The system is not an app, though it’s not clear what it is. Presumably it’s just a website that gets loaded via the QR code.

    Move the pointer using head pointer on Mac

    • This is a macOS user guide for how to enable the ‘head pointer’ on your Mac, using your built-in camera to follow your head movement and move your cursor. I was pointed to this via Stefan’s Web Weekly newsletter.
    • It’s quite effective and worth experimenting turning it on to get a feel for what it is like. You may need to adjust the pointer speed as otherwise the cursor may not move enough in sync with your head.

    A day in the life: What it’s like to travel through an airport and on a plane as a wheelchair user

    • An interesting read about just what a wheelchair user goes through on a typical flight. These users must be transferred into a narrow aisle chair (designed to be able to fit in the aisle of the plane) and then transferred into an airplane seat. Their wheelchair is put in the hold.
    • Going through security is difficult as the wheelchair makes the metal detector check redundant, so these passengers have to have a pat-down, which can slow the process down considerably. TSA PreCheck is an option for American fliers to skip the security check.
    • In May, Gabrielle deFiebre travelled from New York to Phoenix on a Delta flight. Her wheelchair was damaged by employees in an incident recorded in a now-viral video. In 2019, airlines damaged more than 10,000 wheelchairs. All Wheels Up is an organisation advocating for allowing wheelchair users to be able to stay in their own wheelchairs during flight.
    • deFiebre doesn’t eat or drink much at all on flights, knowing the difficulties of transferring into the aisle chair and then into the cramped airplane bathroom.

  • week11y issue 85

    After a few days off work, I return to deliver your weekly frequent11y newsletter. This week is quite a dev/design heavy one!

    Your Image Is Probably Not Decorative

    • Eric Bailey explains why most images nowadays need some form of alternative text.
    • You can ‘nullify’ images – removing them from the screen reader experience – by adding an empty alt text, i.e. <img alt="" ...>. This should only be used when the image doesn’t convey information that is important to understanding the purpose of the page or view.
    • You might nullify your images in the following scenarios:
      • Old layout techniques requiring ‘spacer’ images
      • Where the image repeats content that is already in the page (though this could still be confusing for screen reader users who have partial vision)
      • Supplemental icons (e.g. <button><img alt="" src="icon.svg"> Print</button>).
    • Eric also explains how you can provide alt text when using CSS background images (hint: it uses the spacer gif!)

    The accessibility stalemate

    • Chris Heilmann talks about how the accessibility community holds back the accessibility movement by setting the pedestal too high.
    • There are plenty of great talks about accessibility, but, apparently, many speakers don’t release their slides afterwards. Why? Because people “call out any accessibility problems with the materials”. If the content isn’t 100% accurate, or the platform has one or two of its own accessibility issues, then the materials don’t get released and people aren’t able to benefit from them.
    • Chris says “I saw many conferences not release any of the materials or videos as they couldn’t caption them or host them on a platform that allows for it.” He says that some people enjoy criticising articles for the platform they are published on, e.g. “Isn’t it ironic that I can’t read your article on mobile best practices on my mobile device?”
    • “On the surface, it seems to be valid criticism to call out when [presentations] fail to provide alternatives for each image and video in them. Except, it is a cheap shot and feels like a distraction from the problems the materials talked about.”
    • Controversially, he suggests that not all content needs to be accessible. “What do we gain by ensuring that a presentation about how people use screen readers is accessible by a screen reader? Is that the audience? The one who already knows this information?”

    From A Colourblind Designer To The World: Please Stop Using Red And Green Together

    • A designer with deuteranopia – red/green colourblindness – writes about how the use of green and red in web design is problematic. Namely:
      • Using colour to indicate validation status in forms. Adding other visual indicators such as icons would help to differentiate.
      • Using green and red to indicate primary and secondary actions, e.g. “OK” and “Cancel”. Using fill colour just for the primary action helps to disambiguate.
      • Red and green used to convey meaning in charts – literally unusable for people with colourblindness.
    • If you have to use red and green in your design, choose different luminosity (i.e. make either the red or the green darker and saturated). UK traffic lights look quite similar between red and amber, but the green is very distinct because its saturation is different from the other two.
    • Colourblindness affects 1 in 12 men and 1 in 200 women.

    New in ARIA 1.2: ARIA IDL attributes

    • Scott O’Hara writes about the new ARIA IDL (Interface Definition Language) attributes, allowing you to set element attributes succinctly in JavaScript via foo.role = 'checkbox' and foo.ariaChecked = false. Until now, we’ve had to use setAttribute, i.e. foo.setAttribute('aria-checked', 'false').
    • This is supported in all Chromium browsers, but currently not in Firefox.
    • It’s not yet possible to set attributes in this way if they take multiple IDREFs. For example, aria-labelledby="id1 id2 id3" has no new corresponding IDL attribute yet.

    Your weekly frequent11y newsletter, brought to you by @ChrisBAshton:

    Experimental Brain Implant Lets Man With Paralysis Turn His Thoughts Into Words

    • A fascinating article describing how a paralysed man has had a device implanted into his brain, which decodes signals in the brain that once controlled his vocal tract. After several months of training, the system has a vocabulary of 50 words and the man can communicate at a rate of 15 words per minute. Normal speech is in the region of 120-150 words per minute. A professor at Stanford University acknowledges the 50-word vocabulary as a “huge achievement”, but also feels the vocabulary “could easily become 500 or 5,000 words.”
    • The anonymous patient in question is in his 30s, and has been unable to speak since a stroke 15 years ago. His arms, legs and vocal tract are paralysed, but the areas of the brain that once issued speech commands are intact. There was initially some doubt that the speech commands in the brain would still work after 15 years without use.
    • An ethical dilemma raised in the article is that it will be possible to “eavesdrop” on the brain. We need to ensure that such devices “allow people to be able to think their private thoughts without anything just being broadcast to the world”. This “may be easier with devices that rely on brain signals that control muscles, because these signals generally aren’t sent unless a person makes a conscious attempt at movement”.

    Microsoft: Accessibility is a focus in Windows 11

    • Windows 11, announced at the end of June, is being designed “with accessibility in mind”.
    • The OS will include dark, light and customisable themes, and the improved Closed Captions will be more customisable too.
    • Microsoft have rebranded the old “Ease of Access” setting to the more idiomatic “Accessibility”, to make it easier to find your settings.
    • Like Windows 10, the new OS will include assistive tech including Narrator, Magnifier, Closed Captions, Windows Speech Recognition and Windows Voice Typing.
    • Finally, Windows 11 will support Linux applications via something called WSL (Windows Subsystem for Linux), which is being carefully developed to integrate with assistive technologies.

    Will Accessibility Become Increasingly Important for SEO?

    • A deque blog post, with no clear answer – but an interesting topic nonetheless.
    • Google has for years made mobile usability and speed a factor in SEO – Search Engine Optimisation – meaning that they favour websites which work well on mobile and load fast, and in turn, rank the website more highly in search results.
    • Google states that “everyone should be able to access and enjoy the web. We’re committed to making that a reality”. Google’s Lighthouse tool, which measures website performance and accessibility, provides accessibility scores which could very well lend themselves to an SEO ranking algorithm in the foreseeable future.
    • The article acknowledges that there is already a coincidental link between accessibility and SEO. Accessible pages tend to be well marked up pages, containing metadata, descriptive link text and headings, and alt text.

    Accessible Overflow

    • A fascinating insight into browser behaviour by Marcus Herrmann. When navigating ‘overflow’ content, i.e. text that doesn’t fit inside its container, this requires us to scroll through the content. Many of us would simply use the mouse wheel to scroll within those containers, but how about users who navigate by keyboard? Keyboard users use the up and down arrows to move up and down the page, but what about the overflow content within the page?
    • Firefox automatically puts such content in the tab order, making it reachable and its contents scrollable. In Chrome, Edge and Safari, however, overflow content is not scrollable with a keyboard by default. There is a Webkit issue and a Chrome intent to ship, but otherwise developers are stuck using the following workaround:
      1. Add tabindex="0" to the container
      2. Apply focus styles to the container, e.g. .my-owerflowing-div:focus { outline: 2px solid; }
      3. Add role="region" and supply an accessible name using, for example, an aria-label.
    • Adrian Roselli wrote about this in more detail in Keyboard and Overflow.

    Coursera accessibility courses

    Managing focus in the shadow DOM

    • Web developer Nolan Lawson writes about the difficulties of managing focus on a web page which makes use of the shadow DOM; parts of the page that are encapsulated and unable to be interacted with programmatically in the same way as regular DOM elements.
    • If you’re implementing a modal dialog, you need to manage focus and prevent the user from tabbing outside of the modal window whilst it’s active. This is easier said than done; a common implementation is to use querySelectorAll to find all interactive elements in the page, finding the first and last focusable elements within the modal, and then using a listener to hook into the tab key and overriding where it triggers the focus. But document.querySelectorAll won’t return any shadow DOM elements, so the browser could still allow you to tab into a shadow DOM area outside of the modal.
    • Nolan proposes a new API; element.getNextTabbableElement() and element.getPreviousTabbableElement(), delegating this heavy lifting to the browser. For now, we’re left manually traversing through the DOM and inspecting each element recursively to see if it has a shadow DOM child, to create our list of all interactive elements in the page.
    • My old team at the BBC also wrote about how they migrated away from iframes to the shadow DOM.

    Coronation Street highlights the challenges faced by disabled people working from home during the pandemic

    • This story focuses on Izzy Armstrong, played by Cherylee Houston. The storyline goes that Izzy is clinically vulnerable and has been shielding and working from home throughout the pandemic. Her job is now at risk as her boss insists she returns to the office.
    • The actor Cherylee has in real life been shielding since March 2020, as when she was 23 she was diagnosed with a rare condition called Ehlers-Danlos syndrome.
    • This will be the first time viewers will see Izzy in her real-life home environment. The scenes were filmed by Cherylee and her partner at their Manchester home.
    • “Izzy Armstrong’s upcoming storyline on Coronation Street highlights the reality of many disabled people’s struggles across the UK.”

    Why debate non-text contrast of UI elements?

    • An article by Dave House, describing how WCAG 2.1 Non-text contrast has enough wiggle-room in it that designers often dismiss it, saying “UI elements don’t need to meet this requirement”. He explains: the success criterion states “if the visual indicator of the control is the only way to identify the control, then that indicator must have sufficient contrast”. Therefore, for example, a “Submit” button whose background colour has low contrast is still recognisable with the background colour removed, provided it is in the context of a form, and thus doesn’t fail the criterion.
    • Dave suggests a simple test: for every interactive UI element with a contrast of less than 3:1, remove the thing that is low contrast (be it the text, the background colour, the border, etc). Then review the page and see if it still makes sense. The argument is hard to swallow when Dave uses the Facebook and Google landing pages as examples – if they can’t get it right, what chance do the rest of us have? – but it’s a good rule of thumb nonetheless, and a useful design tip to keep in your arsenal.

    Blind York student wins £5k claim over ‘inaccessible’ loan form

    • Disability rights activist Holly Scott-Gardner, has won a settlement after being unable to fill in a student loan disabled students application form, because it was inaccessible to her (as someone who is blind). Holly had to fill in the form over the phone, after several failed attempts online, and successfully sued the company for a breach of the Equality Act 2010.
    • Holly wrote a long Twitter thread about her interaction with the company, pointing out that they offered to “work with” her on making their services accessible, but this a) isn’t her area of expertise to be a consultant on, and b) they weren’t offering to pay her for her time. The thread is full of great quotes:
      • “In what world is it acceptable to expect the person who has had their rights violated to come and educate you out of the goodness of their heart?”
      • “I am not a token minority. I do not exist as an educational tool for non-disabled people.”
      • “It’s frustrating that everyone seems to view disabled people as experts on every aspect of being disabled. I know I can’t access something, that doesn’t automatically mean I can fix it.”

    Kellogg’s: a game changer in accessible packaging

    • In partnership with RNIB, Kellogg’s has trialled including NaviLens codes on its packaging, giving visually impaired customers a way of scanning products to find out their ingredients, allergen and recycling information.
    • NaviLens codes work in a similar way to QR codes, but can be detected “in a fraction of the time, from up to three metres away”. RNIB and Kellogg’s deduced that NaviLens catered to more people with sight loss, rather than those with specific requirements (such as braille users).
    • 97% of the trial’s participants agreed they’d like to see more of these accessibility features available on grocery packaging.
    • There’s a 5 minute video explaining more about the project.

    Screen Reader User Survey #9 Results

    • The famous WebAIM survey this year had 1568 responses, mostly from North America and Europe, with a pretty even age split. 92.3% of respondents said they have a disability, almost 80% of which was blindness.
    • 57.5% of respondents class themselves as “advanced” screen reader users, versus 37.4% “intermediate” and 5.1% “beginner”. This roughly correlates with their self-assessed levels of “Internet Proficiency”.
    • JAWS is the primary screen reader for over half of respondents, followed by NVDA on around 30%. VoiceOver counts for just 6.5%. This is a decline for NVDA and VoiceOver compared to previous years. Windows Narrator is the primary reader of less than 1% of respondents, but is “commonly used” by 41% of them, compared to 30% in 2019.
    • Chrome is the browser of choice for 53.6% of respondents, followed by Edge at 18.4% and Firefox at 16.5%. Chrome and Edge usage has increased notably. JAWS with Chrome is by far the most common screen reader & browser combination, at 32.5%. 91.1% of respondents use Windows, vs 6.5% on Mac.
    • 72% use iOS mobile devices, vs 25.8% on Android. This corresponds roughly with mobile screen reader usage of 71.5% on VoiceOver and 29.1% on TalkBack, and with choice of browser (Safari: 61.6%, Chrome: 24.2%).
    • 99.4% of respondents have JavaScript enabled.
    • Almost two thirds of screen readers report that they are “very satisfied” with their primary screen reader, and almost a third “somewhat satisfied”.
    • When asked how often they use “skip links” when available, 17.5% said “Always”, 15% said “Often”, 29.7% said “Sometimes”, 22.7% said “Seldom” and 15% said “Never”. Whilst very mixed results, these are largely unchanged from the 2017 survey.
    • Around 39% say web content has become more accessible this year, but around 42% say there has been no change, and 18.5% say content has become less accessible.
    • The majority of screen reader users navigate pages by working through the headings first. About 85% of users find the use of heading levels either very useful or somewhat useful.

    Accessible design: How much motion is too much motion?

    • Heather Waroff, Senior Designer at Microsoft, writes about interaction design. The most useful part of the article for me was the list below, developed “in conjunction with Accessibility specialists”. It describes the types of motion that are considered safe (good), risky (‘it depends’), and non-compliant (bad).
    • Safe Motion:
      • Motion under 5 seconds, of the following types:
        • Show/Hide
        • Glowing
        • Color Transitions
        • Slides
        • Scaling
        • Fading
        • Glyph Transformations
    • Risky motion
      • Any motion longer than 5 seconds
      • Background Parallax
      • Object Parallax
      • Bouncing Effects
      • Fast Effects
      • Image Masking on Scroll
      • Full Width Mask on Scroll
      • Zoom on Scroll
      • Scale on Scroll
    • Non-compliant motion
      • Any motion longer than 5 seconds without a pause button
      • Strobe Effects
      • Rotate on Scroll
      • Fast exit on Scroll
      • Horizontal Directional Scrolling

    What Happens When a Blind Person Test Drives VoiceOver Recognition?

    • An article by Rhea Althea Guntalilib, describing her experience of using the new “VoiceOver Recognition” features of iOS 14. It is a collection of tools including “Screen Recognition” (which I’ll talk about below), “Text Recognition” (which detects text found in images) and “Image Descriptions” (which describes image contents). These features are accessible via Settings > Accessibility > VoiceOver and can then be quick-selected via the VoiceOver rotor.
    • I covered Screen Recognition in dai11y 22/12/2020: “It uses AI to detect interactable elements on the screen, even when such elements aren’t properly labelled / exposed to assistive technology. It has the potential to allow blind users to use apps that are otherwise inaccessible.”
    • Rhea found the Image Descriptions improved her experience of the Facebook and Instagram apps, and also Text Recognition was great at describing her screenshots of captured text messages. Screen Recognition came in handy for her banking apps, which otherwise have no accessible way of transferring funds or paying bills. But she did find she had to turn off Screen Recognition in places, e.g. to properly access the list of available banks, as it would interfere with how VoiceOver worked. Other apps, such as email, had attachments that could not be processed by VoiceOver Recognition.
    • In summary, whilst it has some glitches and limitations, it has “delivered many improvements in the user experience of a blind iOS customer”.

    Accessible SVGs

    • Think you know SVGs? This article is worth a read – you just might learn something.
    • SVGs have an implicit WAI-ARIA role of “graphics-document“. You should only change this if the SVG only contains an image; an attribute of role="img" or role="graphics-symbol" would be appropriate.
    • Hide decorative SVGs from screen readers using aria-hidden="true" – not role="presentation", as this doesn’t hide the contents of the SVG from screen readers.
    • SVGs can have a <title> attribute which acts like an alt attribute on a normal image. It has to be the first child element within the <svg>. There is also an optional <desc> element which can follow this, and should be used to present more detailed textual information. Browser support for both of these is good but not 100%; aria-label can be added for wider support.

    Practical accessibility, part 2: Name (almost) everything

    • It’s not enough to just use semantic markup to, say, create a list in HTML (the “what”), and mark it up with a role="menu" (the “how it’s supposed to work”). We also often need to label the list, to explain “why” it’s there. For example, an aria-label="Main menu" to give some extra context to screen reader users.
    • This article describes how and when you should name things in HTML. It covers the basics, such as associating a label with an input, which effectively gives the input a name, but it also covers the stuff that is more easily omitted, such as applying a label to your ARIA regions.
    • Not every landmark needs a name, but any navigation, form and region should, as well as main (it’s good practice to associate the H1 element with the main content in your page via aria-labelledby). Landmarks that appear once per page, such as banner, should not have a name.

    Online Instruction Did Not Make Things Easier for Disabled Students

    • An interesting article, worth reading as it goes against the current narrative that the disabled community have benefited from the move to online tuition. It covers university undergraduates and graduates in America.
    • “Only 20% of [American] undergraduate students with disabilities reported enjoying online learning, and over one third of students with disabilities reported no increased satisfaction with online learning in general”.
    • The story changes slightly for graduate students with disabilities, who liked online learning more than those without disabilities, but also felt less productive and more disconnected from professors.
    • That said, there were some areas where “disabled students did describe a greater satisfaction than non-disabled students”, such as “comfort levels in speaking up in class” and “connection with other students”.
    • Learning from home rather than university “meant being removed from the protective factor of the university”. Shockingly, only 40% of undergraduate students with multiple disabilities have a “place to live that is free from physical or emotional violence or abuse”.

    Overview of accessibility testing using DevTools (Microsoft)

    • A guide by the Microsoft Edge DevTools team, though almost all of it applies to any modern browser.
    • This mammoth article is a 23 minute read, and covers how to use DevTools for automated accessibility testing, by working through the accessibility ‘warnings’ in the console. It then describes how you should manually test your page by:
      • Resizing the viewport to simulate a zoomed in or mobile device.
      • Attempt to interact with the page with a keyboard, and keep an eye out for focus styles.
      • Inspecting the Accessibility Tree to check for elements with a “generic” role (usually attributed to being encoded as a div or span rather than a button), which won’t be available to users of assistive technology.
      • Simulating hover/focus states on interactable elements and checking their contrast.
      • Testing with dark and light themes.
      • Emulating vision deficiencies with things like blur filters.
      • Verifying that the page respects the prefers-reduced-motion media query.
    • It’s worth at least a skim through – chances are you’ll learn something!

    fingerspelling.xyz

    • This is a website that gamifies teaching you sign language. It uses your webcam to recognise sign language hand gestures, and works extremely well! You gradually progress through different levels of difficulty, eventually covering the entire alphabet.
    • The game is an initiative by digital creative studio Hello Monday and the American Society for Deaf Children.

    Why your brain loves closed captioning

    • 18% of the UK population regularly uses closed captioning, of which only 1 in 5 actually have hearing difficulties. Why?
    • The article cites lots of reasons, such as helping with learning a new language. It can also be useful for people with autism and ADHD by providing “deeper context clues”. It also covers situational impairments, such as when sirens or other noises from outside drown out the sound of the movie. And of course, captions allow you to catch up on content on your phone, without disturbing the person next to you.
    • “We can read faster than we can speak,” says Dr. Stephen Christman, a cognitive psychologist and professor of psychology at The University of Toledo. “With closed captioning on, the viewer can quickly read the current dialogue and then turn their attention back to the visual action and use their knowledge of what is being said — and what is about to be said — to enhance their appreciation of the nonverbal/visual aspects of what is happening on the screen.”
    • The article cites some downsides, however: “It can really wreck a great punchline or suspenseful twist, making it ill-suited to anything that relies on surprise. It can be irritating when it’s poorly executed and riddled with errors.”

    Accessibility Advocates Sign Open Letter Urging People Not To Use AccesiBe and Other Overlay Products

    • Over 400 accessibility advocates and developers have signed an open letter calling on the industry to avoid using controversial “accessibility overlay products”, the most famous of which is accessiBe. These ‘widgets’ you can install on your website often claim to make your site WCAG compliant, by pulling in third party scripts to ‘fix’ problems such as missing alt text.
    • The document lists first-hand accounts from people with disabilities struggling to use websites that have implemented overlays.
    • It also describes the privacy issues of such overlays, which detect when assistive technology is running on the device, exposing the fact that the end user has a disability, with no option for them to choose whether or not to disclose it themselves.
    • The document recommends that people fix the underlying accessibility issues at source, and abandon use of quick fixes such as these, as they are not effective.

    Emojis and accessibility: How to use them properly

    • Ryan Tan shares some tips for accessible emoji usage, mostly in terms of screen reader support, and covering a mixture of ‘design tips’ vs ‘everyday content’:
      • Design: on buttons, don’t use emojis to replace words. E.g. use “Like” rather than “👍”, which could be ambiguous.
      • Don’t use repeated emojis, e.g. “Flight plans ✈️✈️✈️” as each emoji has alt text read out by a screen reader, and this is unnecessarily noisy.
      • Put your text / call to action first, then emoji, i.e. “Let’s go 👊” vs “👊 Let’s go”.
      • Put your emoji at the end of the sentence, not mid-sentence.
      • Use widely-known emojis to cater for as many users as possible, e.g. “Hello 👋” vs “Hello 🖖”.
      • Avoid emoticons, i.e. :) vs 🙂. Some emoticons are particularly difficult to understand as a screen reader user, e.g. the ‘shrug’ emoticon ¯_(ツ)_/¯.
      • Controversially, Ryan suggests you “avoid dark or light skin colour in emoji use” and use the ‘default’ yellow for emojis that have a high contrast on both light and dark backgrounds. There’s a linked article in one of the comments that goes into this topic further, suggesting using emojis that don’t communicate race or gender at all, such as “😸”, or to always use the full range of skin tones such as “✋🏿✋🏾✋🏽✋🏼✋🏻”.

    Our development approach for accessible front-end code

    • This guide by the BBC walks through their approach for implementing front-end changes, e.g. implementing a component.
      1. Look at the screen reader UX; ask the UX designer for the required documentation if it is missing. It should cover the focus order, the announced content for screen readers, etc.
      2. Read accessibility acceptance criteria
      3. Write the HTML
      4. Check with supported assistive technology (AT). You should do this before adding CSS, and then again before and after adding JavaScript. They advise against doing all your testing at the end, as this “may be more time consuming to debug”, since you won’t necessarily know which layer caused the bug.
      5. Write automated tests for accessibility
      6. Get it reviewed (code review by engineers, design review by designers)
      7. Hold an accessibility swarm, resolve any bugs, then the component is ready for Test.

    Whose nine is it anyway? (Feedback on the WCAG 2.2 working draft)

    • This article – which I read mostly for the terrible headline – was written by TPGi, an “accessibility solutions provider”, working with a consortium of big names in a11y. TPGi feel that the 9 new Success Criteria recently proposed for WCAG 2.2 all need some clarification and improvement (with the exception of 2.5.7 Dragging Movements, which TPGi are pleased with).
    • It’s a long article of recommendations, each linking to separate GitHub issues raised by TPGi. But to take an example, some feedback for “3.3.7 Accessible Authentication” includes ensuring copy-paste is not blocked: “The “Intent” section of the non-normative Understanding document mentions that copy-paste must not be blocked, but this is not in the text of the SC. We feel it would need to be in order to ensure that it’s a requirement.”.
    • It’s fascinating to watch the community shape the WCAG standards of the future, and inspiring that any one of us has the power to propose improvements.

    This individual shows how he lives his everyday life as a blind person

    • A colleague shared this in our work Slack. Anthony S. Ferraro (asfvsion) demonstrates how he completes everyday tasks as a blind person. He covers the very basics (how to pour a cup of water; by keeping one finger over the rim of the cup and stopping pouring when he feels liquid), to the extreme (how to skateboard on a half-pipe; by mapping out the area with his cane and then basically going for it). He shows just how important tactile controls / labels are on products, e.g. the oven and washing machine, which would be extremely difficult to use otherwise.

    TikTok Adds New Accessibility Overview To Provide Additional Support for Users

    • TikTok adds photosensitivity warnings to its videos, and allows viewers to opt out of viewing them. It’s also educational; warning labels are shown to creators on the specific effects that may trigger photosensitive epilepsy.
    • TikTok also offers auto captions and text-to-speech tools, and the ability to switch between animated and static thumbnails.
    • These features are described on TikTok’s Accessibility Overview page, which serve as a handy reference point.
    • Anecdotally, TikTok is often seen as very accessible compared to other social media platforms, so it’s always worth noting the improvements they’re making in this area.

    WebAIM Screen Reader User Survey #9

    • One of the most important surveys on the web is back, with a close date of June 15th. The survey is aimed at all screen reader users, including those who just use screen readers for evaluation and testing.
    • The last survey of this kind was in September 2019: Screen Reader User Survey #8. It received 1224 responses – it would be great to get this number higher this year.

    The perfect link

    • Rian Rietveld tackles all the common questions around links:
      • It is usually better to stick with the browser default behaviour, i.e. don’t open links in new tabs/windows. However, it’s OK to do so if you make it clear (“Opens in new window” in the text of the link).
      • Link text should be meaningful and understandable on its own. “Click here” is about the worst link text there is. Proper link text is much easier to scan.
      • For emails, use mailto:someone@example.com as your href. For telephone numbers, use tel:+31108429259; these will open emails in email clients and make phone calls respectively. For the link text, it’s a good idea to repeat the email and phone numbers, rather than using “email” and “call us”.
      • For linking to files such as PDFs, but the filetype and size in brackets, e.g. “Web Accessibility Principles (PDF, 327 Kb)”.
      • When embedding images in a link, use alt text that makes sense as link text, e.g. “Wikipedia page on cherry blossoms” rather than “A cherry tree in full bloom”, as the image alt text will get read out by screen readers as part of the link.
      • Links in the body should generally be underlined – relying on colour difference alone isn’t distinguishable for colour-blind or visually impaired users. Links in navigation need not be underlined, as these are more obviously links.
      • As always, ensure your links have hover and focus styles. Rian recommends not removing the browser’s default outline.
      • For internal links, your href attribute should point to an ID – not to another link with a name attribute, which has been obsolete since HTML5.

    We need to talk about WCAG

    • This article is written by Rian Rietveld (my second article in a row by this author, by pure coincidence!)
    • 97.4% of home pages have detectable WCAG 2 failures. Rian concludes that this is a failure in the way we communicate and teach WCAG, which she thinks is partly down to the information architecture of the WCAG docs. When arriving at a W3C page from a search engine, it can be hard to know if a document is a draft, if it is outdated, and whether it is WCAG 2.0 or 2.1. A lot of old W3C content is indexed by search engines, and sometimes it is the old page that is the one at the top of the search results.
    • Rian describes a real world example; searching for “title attribute WCAG”, clicking on the first result, and copying the code example results in code that is bad practice, though not technically a WCAG violation as it is a “Technique” rather than a “Success Criterion”. Rian expects many developers won’t know the difference between the two.
    • Some new Success Criteria will be added in WCAG 2.2; Rian suggests this is counterproductive while so many existing Success Criteria are ignored. She has raised a GitHub issue, and invites you to add a comment.
    • Rian proposes:
      • Adding a message to the top of every out-of-date page saying that it has been superseded, and link to the latest page. Add noindex to these pages to prevent search engines from continuing to index them.
      • Consolidate content about Techniques, Success Criteria and Understanding, so that each topic only has one page. Use the WAI website for education and tutorials.

    Testing fonts for accessibility

    • Colin Shanley shares the 3 things to bear in mind when choosing a font:
      • Imposters: specific letter shapes that look similar to other shapes can be difficult or impossible to differentiate. For example, lowercase L, uppercase i and the number 1. The image below shows Gill Sans on the left (bad) vs Assistant on the right (good):
      • Mirroring: letter pairs (such as lowercase P and Q) should never be the mirror image of one another, as some people flip letters back to front in the brain shape translation process. The image below shows Helvetica on the left (bad) vs Raleway on the right (good):
      • Discernibility: looking at the apertures of shapes (the openings, e.g. the right-hand gap at the opening of the letter “c”), are they close enough that they could be confused with another letter (e.g. “o”)? The image below shows Public Sans on the left (bad) vs Commissioner on the right (good):
    • There is also WCAG SC 1.4.12 to consider. When a user overrides any of the following style properties, your page text should not disappear or overlap other page content:
      • Line height (leading) to at least 1.5x the font size;
      • Spacing following paragraphs to at least 2x the font size;
      • Letter spacing (tracking) to at least 0.12x the font size;
      • Word spacing to at least 0.16x times the font size.
