Screen readers and JavaScript

Last week at CSUN I spent a large proportion of my time focusing on sessions and workshops that looked at JavaScript, screen readers and Web 2.0. Overall it was an interesting week with some great presenters one of which was Steve Faulkner from the Paciello Group who ran a one day workshop on “Screen readers and JavaScript”.

Originally scheduled to co-present with Gez Lemon, also of the Paciello Group, Steve found himself presenting solo for the first half of the day after Gez’s plane got cancelled due to blizzards. Charles Chen, the man behind Firevox, stepped up to the table mid afternoon to do a session on AJAX, live regions and accessibility as well as demo Firevox and it’s capabilities. Firevox is an open source suite of extensions for Firefox that make Firefox into a talking browser for the visually impaired.

Further useful resources focusing on JavaScript and how it can, or can’t, work with screen readers can be found at:

    Accessible Rich Internet Applications (WAI ARIA): WAI-ARIA defines how to make more advanced features of dynamic content and rich Internet applications accessible to people with disabilities. A primary focus of WAI-ARIA is providing information about user interface controls—such as expanding navigation bars—to assistive technology.
    The JavaScript Dojo: Dojo is an Open Source DHTML toolkit written in JavaScript. Dojo aims to solve some long-standing historical problems with DHTML which prevented mass adoption of dynamic web application development.

Multiple web accessibility assessments

There’s been an awful lot written recently about the accessibility assessments in Socitm’s Better Connected reports. Some of it has been… well, let’s just say that some of it has been less than accurate! So here’s a detailed overview of the process we use for carrying out multiple assessments for projects like Better Connected, with some of the background about how we developed this process.

South by Southwest (SXSW)

I’m off on the conference trail again, this time to SXSW, where I’ll be watching and listening to some of the biggest names in the web world talk about the next big things and trying to figure out what that means in terms of accessibility.

With any luck, the wireless access there will be up to scratch, and I’ll be able to blog my thoughts and experiences as I go. So if you’re not one of the many attendees this year, keep an eye out for my posts.

If you are attending and see me around, do say hi.

Once more, I’ll be the one with the Dell rather than a MacBook.

Technology & Persons with Disabilities Conference, March 19-24 Los Angeles, USA

I’m very much looking forward to co-presenting with Shawn Henry from the Web Accessibility Initiative (WAI) at this year’s CSUN conference. We’ll be talking about “Transitioning Your Web Accessibility Project from WCAG 1.0 to WCAG 2.0″.

We’ll be giving a practical insight for web designers, developers and owners to assist with planning and approaches for making the move from WCAG 1.0 to 2.0. I’ll be around from Monday and look forward to meeting and seeing some of you there.

BC2007 is out

At last, after much toil and angst, Socitm’s Better Connected 2007 report is published.

Better Connected 2007: a snapshot of local authority websites

I want to mention one particular result here, since you’re guaranteed to see it mentioned elsewhere.

Dan Champion’s excellent website at Clackmannanshire council failed to achieve a pass at Level Double-A.

Why? Because in the 200 page sample, the automated test indicated 158 HTML validation errors. I checked that result manually shortly after it came in, and found a scattering of validation errors consistent with that number of errors being found over that number of pages.

Does this mean that Socitm or RNIB are saying that the website is inaccessible?

Don’t be daft. Of course not! What it means is that, at the time of testing, the site failed to achieve full compliance with all of the requirements of the WAI WCAG 1.0 guidelines at Level Double-A.

Because that’s what we assess for the Better Connected reports. The UK government specifies Level Double-A as the target for central government and local authority websites, so we test compliance at that level. And these assessments are a snapshot in time - resources simply don’t allow for any more in-depth or complex than that.

I outlined in a previous post here the methodology we use for these assessments, which involves a combination of automated and manual testing. And we include various margins in the automated tests to ensure we’re not failing sites because of a single missing ALT attribute or something equally draconian. For example, if fewer than 5% of all the images found in the sample lack an ALT attribute, the site will be given a provisional or “marginal” pass for that checkpoint, so that it can go forward for manual checking. Similarly, if we record fewer than 50 HTML validation errors, that checkpoint is given a “marginal” pass.

Confession: knowing how knowledgeable and committed to accessibility Dan is, I did, for a few seconds after I saw that result, consider the fact that I could quietly change the number at that point and no-one, except me, would be any the wiser. But how fair would that have been to other equally committed web managers in a similar position who I happen not to know? Quite. So I didn’t.

I’ve focussed on the Clackmannanshire website since it, and Dan, have rather a high profile. But there may be other web teams who find themselves in a similar position.

So, to Dan, and to any other local authority website managers who are disappointed with the results of our assessments for Better Connected 2007 - I’m sorry. But we have to assess on the basis of what we find at the time we carry out these assessments. We don’t set out to fail sites or enjoy failing them, but we do aim to be as fair and impartial as we can in our assessments.
