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

Impact of Responsive Designs

I heartily concur with Luke’s call for sharing of data:

If you’ve had success with a responsive design, my plea to you is to please share what you’ve learned.

I’m going to see if I can get some Clearleft clients to open up.

Carousel interaction stats by Eric Runyon

I’ve never been a fan of carousels on websites, to put it mildy. It seems I am not alone. And if you doubt the data, ask yourself this: when was the last time you, as a user, interacted with a carousel on any website?

Mobile first: the revolution is well under way - Generated Content by David Storey

David takes a look at worldwide trends in web browsing, pointing out where mobile traffic exceeds desktop …and we’re not necessarily talking about smartphones here either.

It would be possible to travel from the Niger Delta on the west coast of Africa, to the horn of Africa on the east coast, without passing through a country where people surf more on desktop than a mobile phone.

HTML5 test results

As promised, I’ve gathered the data from one of the exercises I administered at the dConstruct HTML5 and CSS3 workshop and totted the results up in a table.

There were 30 people in the workshop but I only managed to retrieve 22 results—I don’t know what happened to the missing eight sheets of answers. This is a smaller sampling than I was hoping for and I realise that it’s too small to be considered scientifically accurate but I think it’s still interesting to see the responses of 22 smart, savvy web developers.

Across the top (in the table header) are the possible answers; nine new elements in the HTML5 spec. Each row shows the answers given for each element as workshop attendees attempted to match up the names of the elements with the nine definitions provided from the spec. The most common answer in each case has been highlighted.

HTML5 Workshop Results
article aside details figure footer header hgroup nav section
article 5 0 2 1 1 1 0 1 9
aside 1 11 1 3 2 0 0 0 2
details 1 6 8 1 4 0 0 0 0
figure 3 2 2 14 1 0 0 0 0
footer 0 0 10 0 10 1 0 0 1
header 0 0 0 2 0 16 0 4 0
hgroup 0 0 0 0 0 1 21 0 0
nav 0 0 1 0 0 0 0 19 2
section 12 0 0 0 1 1 1 0 7

Ideally, the table would show a nice uniform graph: a solid diagonal line from the top left left to the bottom right. The diagonal line is there but it isn’t exactly uniform.

For the record, here are the element names together with their correct definitions. I’ve included a little sparkline with each one to show the distribution of answers. A unanimous result would show one clear spike. Wobbly uneven sparklines indicate a corresponding uncertainty in the answers.

article

…a section of a page that consists of a composition that forms an independent part of a document, page, or site.

aside

…represents a section of a page that consists of content that is tangentially related to the content around it, and which could be considered separate from that content.

details

…additional information or controls which the user can obtain on demand.

figure

…some flow content, optionally with a caption, that is self-contained and is typically referenced as a single unit from the main flow of the document.

footer

…typically contains information about its section such as who wrote it, links to related documents, copyright data, and the like.

header

…a group of introductory or navigational aids.

hgroup

…used to group a set of h1–h6 elements when the heading has multiple levels, such as subheadings, alternative titles, or taglines.

nav

…a section of a page that links to other pages or to parts within the page: a section with navigation links.

section

…a thematic grouping of content, typically with a heading, possibly with a footer.

There are some interesting results here; some of them surprising, some of them expected.

The most easily identified element is hgroup. That’s also the only element name that isn’t taken from an existing English word. I don’t think that’s a coincidence. When the name of an element is created specifically to describe what that element does, it’s no surprise that the name and the definition are tightly coupled.

I was expecting to see more confusion between aside and figure. Both elements serve a similar purpose and in my opinion, the names could be swapped around without changing the definitions in the spec. But the data doesn’t support my hypothesis.

The confusion around footer surprised me. I would have expected to see more confusion between footer and aside than between footer and details.

The most glaring problem lies with section and article. This doesn’t surprise me. At this point, section and article are practically indistinguishable. For a while there, article had some more optional attributes—cite and pubdate—but those have now been removed. Now section and article have the same content model and appear to cover much the same kind of content:

…a thematic grouping of content, typically with a heading, possibly with a footer.

…a section of a page that consists of a composition that forms an independent part of a document, page, or site.

Witness the recent article on HTML5 Doctor wherein Bruce attempts to clear up the confusion and points out where the HTML5 Doctor site has been getting it wrong. If it’s tough for those smart guys to figure out when to use section, article or div, it doesn’t bode well for the rest of us.

Choosing the right element would be easier if there were some clear rules like “You can only use sections within articles” or “You can only use articles within a section” but as it is, you can nest sections in articles and articles in a section. With that much rope, authors are likely to hang themselves, overdosing on the semantic freedom.

I don’t think there needs to be a section element and an article element. I don’t have a particularly strong opinion about which one should stay and which one should go but a little trimming is definitely in order.

Now, if you’ll excuse me, I’m off to present this data to the list.
