Drupal 8, aural interfaces and groundbreaking accessibility at Drupalcon Portland

A switchboard operator for Drupal?

I’m a millennial, but even I remember the experience of calling the telephone operator and getting a live human to look up the number of a business or place a collect call. We have the digital means to complete lots of tasks like that today, but that doesn’t mean all of our methods are equally effective for everyone.

Drupal's new mobile-friendly toolbar“Drupal 8 will be the most accessible version of Drupal yet,” declare J. Renée Beach and Wim Leers in their Drupalcon Portland session description<.

They’re both part of the Spark team<, an initiative to improve the authoring experience in Drupal for everyone.

Spark is more well known for things like in-place editing< and a mobile friendly toolbar<, which you can see at right. But from the beginning, improving the experience for everyone has been a big priority, and one of the most exciting developments is a new aural interface.

That’s right, Drupal is getting a switchboard operator:

OK, so that doesn’t look terribly exciting all on its own. But trust me, when you watch the videos of people interacting with Drupal 8 and having menus and selections read as they go, it’s pretty cool.

When I spoke with J. Renée about Drupal 8 and the nature of working on accessibility, the passion for this work really shown through. I’m really looking forward to their session with Wim, “Drupal Speaks: Aural user interfaces, new Drupal 8 accessibility features,” on Wednesday at 10:45 AM.< Hope to see you there!


IB: What are we missing when we talk about accessibility right now?

JRB: I want developers to understand that accessibility is fundamental to user interface development. We tend to talk about accessibility like we talk about gender. Both have coded values. When we speak of being gendered, we are often talking about being non-male. Male is a kind of genderless base state. So is it with accessibility. When we speak of making something accessible, we tend to refer to making an interface for blind users or for users with physical capabilities that make keyboard and mouse use difficult, as examples. Visual is a kind of accessible base state.

We risk “othering” folks for whom accessibility is an issue because as developers, in general, non-visual accessibility has not been a primary concern. I know what is is like to be othered. In some ways, highlighting otherness can be an effective way to bring focus to a problem. Eventually though, we need to resolve those issues and close the loop on the otherness. We can be other and also be equal. Now is the time for front end developers to start thinking about accessibility as a multi-modal effort. We no longer have the excuse that the tools and technologies available to us do not support efficient workflows for non-visual UI development.

IB: Where is Drupal 8 going to do better?

JRB: Most importantly, we have more individual core contributors this cycle who truly believe in addressing accessibility issues. And they are all smart, wonderful people which makes working with them a pleasure!

For example, take this issue about requirement warnings during installation<. For a sighted user, a warning during installation is immediately apparent. The missing requirement is made distinct with color contrast. For a blind user, they must traverse every cell in the table to discover a missing requirement. Would we ever impose such a burden on a sight user through the UI? No, not without grumbles in the issue queues at least. With more contributors invested in improving these types of non-visual details, we are polishing all the rough edges — the ones we see and the ones we don’t.

IB: How important is context in aural interfaces?

JRB: Context is important to all interfaces. As front end developers we build templates that expose context in a predictable, consumable way. As a practice we have established and then refined patterns of visual expression over the past 30-plus years.

Metaphors grounded visual pointer displays on a virtual desktop. We talk of visual affordances in rounded, gradient-embellished, reflective buttons. Skeumorphic designs< bring our understanding of the physical world to bear on pixels and bits.

Where are the metaphors in aural interface design? I know of none. To me, these interfaces are flat. The metal is bare underneath them.

Perhaps non-visual interfaces have one less level of abstraction to traverse. Maybe there’s no need to translate language into symbol and then back into language. But that little bit of designer in me, that memory of a linguist I almost was, remembers being thunderstruck with insight reading Jackendoff’s< unfurling of metaphor after I had just so recently fallen smitten with the strict generative grammar of early Chomsky<. Jackendoff gives us a way of understanding language that starts at basic physical dichotomies — up/down and near/far — and from there offers us a model of communication. He gives us pattern. (Early) Chomsky gave us metal. So much that we humans do starts with structure that softens with time to fit our curvy, winding nature.

I want to believe that the aural interfaces we have today still just the awkward first attempts to build an abstract audio interface pattern language. That non-visual interface design is still working through its structuralist< phase. We are still learning how to pack context into denser forms through non-visual expressions.

IB: Will the Drupal 8 improvements have things to offer module developers?

JRB: In Drupal 8, we are building tools that manage a couple of the trickier components of accessibility in a browser. These are:

1. Outputting audio updates

2. Managing tabbing in constrained workflows

Module developers will be able to pass a string to a method called “announce” on the Drupal object and have that string read by a screen reader.

Another method on the Drupal object called “tabbingManager” will constrain tabbable elements on the page. A developer will select those elements, either through JavaScript methods or jQuery, and pass them to the tabbingManager. Tabbing is then constrained to those elements until the constraint is superseded or released. I know that must not be completely clear, but that’s why we’re presenting a session about aural user interfaces and how we can use these new tools to build them<!
