How we’ve made GOV.UK Elements even more accessible

A nice run-down of incremental accessibility improvements made to Gov.uk (I particularly like the technique of updating the title element to use the word “error” if the page is displaying a form that has issues).

Crucially, if any of the problems turned out to be with the browser or screen reader, they submitted bug reports—that’s the way to do it!

Offscreen Magazine Interview — by Craig Mod

Craig talks about reading, writing, books, publishing, and Amazon:

Kindle and non-Kindle book sales account for less than two percent of Amazon’s market cap. The Kindle could disappear tomorrow, and Amazon would not be materially affected. Even from a branding perspective, I don’t think AMAZON = BOOKS anymore, certainly not to younger consumers. AMAZON = PRIME. PRIME = A 3D PRINTER on a one-day time-delay that deposits anything you can imagine on your doorstep.

There’s also this about the double-edged sword of working at scale:

Does affecting one hundred lives turn you on? A thousand? A million? A billion? Why? What does it mean to have a positive impact on a life? How intimate does that connection need to be? Understanding your scale — the scale that moves you — is critical to understanding with whom and how you should work, how you should live.

Installing Progressive Web Apps

When I was testing the dConstruct Audio Archive—which is now a Progressive Web App—I noticed some interesting changes in how Chrome on Android offers the “add to home screen” prompt.

It used to literally say “add to home screen.”

Getting the “add to home screen” prompt for https://huffduffer.com/ on Android Chrome. And there’s the “add to home screen” prompt for https://html5forwebdesigners.com/ HTTPS + manifest.json + Service Worker = “Add to Home Screen” prompt. Add to home screen.

Now it simply says “add.”

The dConstruct Audio Archive is now a Progressive Web App

I vaguely remember there being some talk of changing the labelling, but I could’ve sworn it was going to change to “install”. I’ve got to be honest, just having the word “add” doesn’t seem to provide much context. Based on the quick’n’dirty usability testing I did with some co-workers, it just made things confusing. “Add what?” “What am I adding?”

Additionally, the prompt appeared immediately on the first visit to the site. I thought there was supposed to be an added “engagement” metric in order for the prompt to appear; that the user needs to visit the site more than once.

You’d think I’d be happy that users will be presented with the home-screen prompt immediately, but based on the behaviour I saw, I’m not sure it’s a good thing. Here’s what I observed:

  1. The user types the URL archive.dconstruct.org into the address bar.
  2. The site loads.
  3. The home-screen prompt slides up from the bottom of the screen.
  4. The user immediately moves to dismiss the prompt (cue me interjecting “Don’t close that!”).

This behaviour is entirely unsurprising for three reasons:

  1. We web designers and web developers have trained users to dismiss overlays and pop-ups if they actually want to get to the content. Nobody’s going to bother to actually read the prompt if there’s a 99% chance it’s going to say “Sign up to our newsletter!” or “Take our survey!”.
  2. The prompt appears below the “line of death” so there’s no way to tell it’s a browser or OS-level dialogue rather than a JavaScript-driven pop-up from the site.
  3. Because the prompt now appears on the first visit, no trust has been established between the user and the site. If the prompt only appeared on later visits (or later navigations during the first visit) perhaps it would stand a greater chance of survival.

It’s still possible to add a Progressive Web App to the home screen, but the option to do that is hidden behind the mysterious three-dots-vertically-stacked icon (I propose we call this the shish kebab icon to distinguish it from the equally impenetrable hamburger icon).

I was chatting with Andreas from Mozilla at the View Source conference last week, and he was filling me in on how Firefox on Android does the add-to-homescreen flow. Instead of a one-time prompt, they’ve added a persistent icon above the “line of death” (the icon is a combination of a house and a plus symbol).

When a Firefox 58 user arrives on a website that is served over HTTPS and has a valid manifest, a subtle badge will appear in the address bar: when tapped, an “Add to Home screen” confirmation dialog will slide in, through which the web app can be added to the Android home screen.

This kind of badging also has issues (without the explicit text “add to home screen”, the user doesn’t know what the icon does), but I think a more persistently visible option like this works better than the a one-time prompt.

Firefox is following the lead of the badging approach pioneered by the Samsung Internet browser. It provides a plus symbol that, when pressed, reveals the options to add to home screen or simply bookmark.

What does it mean to be an App?

I don’t think Chrome for Android has any plans for this kind of badging, but they are working on letting the site authors provide their own prompts. I’m not sure this is such a good idea, given our history of abusing pop-ups and overlays.

Sadly, I feel that any solution that relies on an unrequested overlay is doomed. That’s on us. The way we’ve turned browsing the web—especially on mobile—into a frustrating chore of dismissing unwanted overlays is a classic tragedy of the commons. We blew it. Users don’t trust unrequested overlays, and I can’t blame them.

For what it’s worth, my opinion is that ambient badging is a better user experience than one-time prompts. That opinion is informed by a meagre amount of testing though. I’d love to hear from anyone who’s been doing more detailed usability testing of both approaches. I assume that Google, Mozilla, and Samsung are doing this kind of testing, and it would be really great to see the data from that (hint, hint).

But it might well be that ambient badging is just too subtle to even be noticed by the user.

On one end of the scale you’ve got the intrusiveness of an add-to-home-screen prompt, but on the other end of the scale you’ve got the discoverability problem of a subtle badge icon. I wonder if there might be a compromise solution—maybe a badge icon that pulses or glows on the first or second visit?

Of course that would also need to be thoroughly tested.

Alt-texts: The Ultimate Guide - Axess Lab

Great advice for writing usable alt attributes. This gem seems obvious in hindsight but I hadn’t considered it before:

End the alt-text with a period. This will make screen readers pause a bit after the last word in the alt-text, which creates a more pleasant reading experience for the user.

What Blade Runner is about, and the Narcissist Creator Razor ( 1 Sep., 2017, at Interconnected)

George Lucas, Ted Chiang, Greg Egan, Stanley Kubrick, Tom Stoppard, William Shakespeare, and Ridley Scott are all part of Matt’s magnificent theory that the play is the thing.

Rosencrantz and Guildenstern are replicants.

Characters look like people, except they exist for only the duration of a movie — only while they are necessary. They come with backstory and memories fully established but never experienced, partly fabricated for the job and partly drawn from real people known by the screenwriter. At the end, they vanish, like tears in rain.

Starting a React-Powered Comment Form | CSS-Tricks

This is a really great screencast on getting started with React. I think it works well for a few reasons:

  • Sarah and Chris aren’t necessarily experts yet in React—that’s good; it means they know from experience what “gotchas” people will encounter.
  • They use a practical use-case (a comment form) that’s suited to the technology.
  • By doing it all in CodePen, they avoid the disheartening slog of installation and build tools—compare it to this introduction to React.
  • They make mistakes. There’s so much to be learned from people sharing “Oh, I thought it would work like that, but it actually works like this.”

There’s a little bit of “here’s one I prepared earlier” but, on the whole, it’s a great step-by-step approach, and one I’ll be returning to if and when I dip my toes into React.

Installing web apps on phones (for real)

Henrik points to some crucial information that slipped under the radar at the Chrome Dev Summit—the Android OS is going to treat progressive web apps much more like regular native apps. This is kind of a big deal.

It’s a good time to go all in on the web. I can’t wait to see what the next few years bring. Personally, I feel like the web is well poised to replace the majority of apps we now get from app stores.

Results of the 2016 GOV.UK assistive technology survey | Accessibility

The Government Digital Service have published the results of their assistive technology survey, which makes a nice companion piece to Heydon’s survey. It’s worth noting that the most common assistive technology isn’t screen readers; it’s screen magnifiers. See also this Guardian article on the prevalence of partial blindness:

Of all those registered blind or partially sighted, 93% retain some useful vision – often enough to read a book or watch a film. But this can lead to misunderstanding and confusion
