Adobe at CSUN 2011 Conference

The California State University at Northridge’s Conference on Disability is going on March 16-18, 2011, and Adobe is offering a number of sessions that we hope people will find interesting and informative, as well as offering opportunities to talk directly to Adobe’s accessibility team and product team members.

The event will feature several sessions and events that I want to provide some details for. Here’s our schedule of events:

Wednesday, March 16

Thursday, March 17

Friday, March 18

The following is not an Adobe session, but it is introducing a valuable resource in the form of a course on accessible Flash development, developed jointly by the Department of Veterans Affairs and SSB BART Group.

Adobe will have several people at CSUN and will be attending the TweetUp as well as being available to talk between or after sessions. Please come introduce yourself and ask questions and share your thoughts.

PDF Accessibility Training for Australian Government

Adobe is running a series of training in Australia the first week of March to help Australian Government employees understand how to create accessible PDF documents. The trainings are being held in Canberra at the National Museum of Australia, but will be recorded and made available online after the sessions (probably with a 1-2 week delay in order to have the recordings captioned and posted). We are running these sessions in conjunction with the Australian Government Information Management Office (AGIMO).

I’m delivering two different presentations (twice each):

  • PDF Accessibility for Everyone – suitable for a wide range of user knowledge of accessibility, focusing on common authoring pathways
  • PDF Accessibility for Techo’s – an advanced session for people with good knowledge of accessibility

More information about the sessions, and registration for attendance, is now available.

I’m looking forward to these sessions and helping people understand how to create PDF documents that meet WCAG 2.0 and are easily used by people with disabilities.

Quick Thoughts On Canadian Legal Ruling

There was an important ruling today on accessibility from the Canadian Federal Court that is worth a read.

A blind woman filed suit against the government of Canada stating that the government “violated her rights under section 15(1) of the Canadian Charter of Rights and Freedoms, Part I of the Constitution Act, 1982″. In short the findings of the court were that many web sites for the Canadian government are not meeting the Common Look and Feel standard (CLF). The Court found that the government should update the CLF standard to utilize WCAG 2.0 instead of WCAG 1.0 and that there is sufficient evidence of compliance problems that need to be addressed that the Court found that the applicant was discriminated against due to the need to access information and apply for employment via these websites. The Court is allowing the government 15 months to come into compliance.

There are a couple of points raised in the ruling and in a Globe and Mail online article (Court orders Ottawa to make websites accessible to blind) that I would like to clarify. The points are as follows:

  • From the ruling: “The applicant testified that in June 2007 she attempted to access information on the consumer price index and unemployment rate from the Statistics Canada website. She stated that actual statistics were, however, only available in “pdf” format, which is not accessible to screen reader technology.”
  • From the ruling: [reported by a witness for the applicant] “…for example, “flash” is a technology that cannot be read by many screen readers. If a website uses “flash” technology, the user will not be able to access that content…”
  • From the Globe and Mail article: “Many blind people use screen readers, computer software that translates electronic text into audio. But the readers aren’t foolproof — for one thing, most can’t decipher PDF files, a format often used to publish documents online.”

None of these is accurate. Even in 2007, most screen readers could read PDF and Flash capably. In fact, the screen reader used by the applicant was capable of reading both PDF and Flash. The points above indicate that most screen readers can’t read PDF or Flash, but it is more accurate to say that most can, including JAWS, Window-Eyes, NVDA, and others. Adobe provides a “read out loud” feature in Adobe Reader that provides basic access to PDF documents, but most users who are blind will depend on a more full-featured assistive technology.

This is not to suggest that the applicant didn’t encounter challenges, she clearly did. Authors of HTML web pages, as well as authors of PDF documents and Flash content need to make sure that they follow accessibility standards, and if authors don’t, users suffer.

We have techniques available for complying with WCAG 2.0 when authoring Flash, HTML, and techniques for PDF are in the works (there are training resources available for PDF at Adobe’s accessibility site in the meantime). The information that authors need is available, this ruling will undoubtedly stimulate an increased interest in these sources of information.

Adobe is committed to helping authors comply with accessibility requirements, whether using HTML, PDF, or Flash. Here’s a few links to relevant information:

Reader X, Accessibility, and Security Sandboxing

Yesterday Reader X was released and with it a new feature for security sandboxing. I want to alert assistive technology users to some implications of this feature, as they may be affected if they are using Windows XP.

Sandboxing works without issue for assistive technology users with Windows Vista or Windows 7. Your version of Reader will install with Protected Mode enabled and you don’t need to do anything different to read or interact with PDF documents.

Windows XP users who use assistive technology have a little different situation. When one of these users opens a PDF file they will get an alert that indicates the following:

“Adobe Reader has detected that you may be using Assistive Technology on your computer. While using Adobe Reader with Protected Mode enabled on Windows XP operating systems, some Assistive Technologies may not be able to read some document content. If you do encounter problems, turning off Protected Mode may help. This can be done by choosing Edit > Preferences > General and unchecking Enable Protected Mode at startup.”

Screen shot of alert that appears when an XP user opens a PDF file while assistive technology is running

What this means is that some assistive technologies are not able to navigate the security sandbox. So, as an assistive technology user, you should first check to see if you are able to access PDF content with your AT – JAWS and Window-Eyes users will need to disable Protected mode in the Reader preferences. There are many assistive technologies and many possible system configurations, so we encourage you to try for yourself. For an accessible PDF file to try, here is a simple test PDF file. Feel free to post your results as comments.

Update: This post initially indicated that Window-Eyes 7.2 was able to read in protected mode, but I received incorrect information on this point and was corrected by contacts at GW-Micro. The key issue is that the sandbox blocks COM interfaces, which includes current accessibility APIs, so it does make sense that Window-Eyes doesn’t work within Protected mode on XP.

IAccessible2 in Adobe Reader and Access to PDF Portfolios

We shared the following about Adobe Acrobat and Adobe Reader at the CSUN conference:
Adobe is working on major accessibility improvements to Acrobat and Reader. Among the expected improvements, enhanced support for accessibility in PDF forms utilizing Adobe’s XML Forms Architecture (XFA) and accessibility support for PDF Portfolios are important for many users.
Adobe is building in support for IAccessible2, a robust accessibility interface provided by The Linux Foundation that allows rich information about both PDF forms and PDF Portfolios to be made available to assistive technologies. Adobe works with assistive technology vendors to ensure that they are aware of ongoing work that impacts support for PDF, and, at the appropriate time, will be providing builds to vendors that are part of Adobe’s Assistive Technology Vendor Program.
These improvements will not impact form authoring practices, but will improve the functionality of existing PDF/XFA forms and portfolios. Accessibility improvements are currently planned for the next major release of Adobe Acrobat and Adobe Reader.

Accessibility and Adobe Open Government

As the leader of Adobe’s accessibility team, I am proud of the commitments Adobe has made to the mission of accessibility and needs of individuals with disabilities. Adobe produces innovative software that enables the development of content that is visually rich and highly interactive, and as a result rendering that content in a productive way for people with visual disabilities can be a challenge – one we take seriously.

Adobe has worked on accessibility standards committees in the U.S. and internationally, including: the W3C’s WCAG 2.0, ATAG 2.0, Timed Text/DFXP, HTML5, and Protocols and Formats working groups; the U.S. Access Board’s TEITAC subcommittee; and the PDF Universal Accessibility work group at AIIM. Two important goals of our participation are to help ensure that accessibility standards are effective at meeting the needs of those with disabilities and to promote technological neutrality. From an accessibility perspective, we believe that developers should be able to use any technology as long as they are able to deliver content that meets accessibility standards and end-user needs.

Adobe Flash and PDF (which is now an ISO standard – ISO 32000-1) both provide support for accessibility, but it is important for authors and developers to learn best practices and understand user needs in order to deliver results that take advantage of the unique capabilities of the formats and that allow all users to access the information and functionality. Authors sometimes will make a trade-off between producing a visually interesting application in a timely fashion and adhering to accessibility requirements. Other times, accessibility gets left to be dealt with at the end of a project that has a firm end-date and when other features take longer than expected, accessibility or other items fall off the schedule. Government agencies don’t get to make these trade-offs as they are bound by law to make their services accessible, but commercial entities don’t have the same requirements and often overlook the needs of people with disabilities when creating web experiences and documents.

Despite our best intentions, Adobe overlooked the needs of people with disabilities in our recently-launched Open Government web site, which failed to meet certain accessibility best practices. Some customers have contacted us and a few bloggers pointed out the issues and we are working to improve the Open Government site. We apologize to everyone who attempted to access the site and was unable to do so. With the benefit now of seeing the site in its present state rather than the initially-planned more dynamic and interactive version, the team is recreating the site using a combination of HTML and Flash. Several improvements to the current Flash-based site have been addressed already. My hope for this post and the intention of the Open Government site is to help other developers learn from this example, and improve their own development practices of visually rich web sites for access by all users.

Whether users need to use assistive technologies such as screen readers or magnifiers, operate their computer with the keyboard alone, view larger text sizes, view captions or subtitles for audio information, or utilize many other accessibility features, these features already exist in Adobe products. And while these are not perfect in all products yet, we are dedicated to enabling our tools to handle accessibility in robust and reliable ways.

If you are interested in learning more about accessibility in Adobe products, I’m providing some interesting links below. As always, we value the feedback of our customers and end users, so let us know your thoughts.
