Historically, typical PDF files have offered AT usersa poor experience. The rules of accessible PDF were fuzzy enough to stymie development of more and better tools.
Berlin, Germany (PRWEB) June 28, 2012
NVDA is a free, open-source screen reader; a type of assistive technology popular with users with visual disabilities. Screen reading software offers efficient access to many software applications and well-designed websites, but PDF files have presented special challenges for years.
For access to content, screen readers and other assistive technologies depend upon a specific feature of PDF known as “tags”. While tagging PDF files for accessibility purposes became possible in 2001, the technical specifics were ambiguous. To ensure a consistent experience software developers and service providers need a single set of technical rules for accessible PDF files. Responding to the need, AIIM started the PDF/UA Committee in 2004 to draft these rules. That process led to ISO 14289-1, the International Standard for universally accessible PDF, to be published in Q3 of 2012.
Designed to work in conjunction with WCAG 2.0, the new PDF/UA international standard allows document creation and processing software to ensure conforming files and software are capable of delivering PDF content to assistive technology users in a consistent, high-quality fashion.
Assistive technology is the means by which many disabled users interact with computers. While specific needs of assistive technology end-users vary greatly, PDF/UA requires conforming technologies to be able to process the full set of accessibility features available in PDF. A rich, detailed reading experience is possible within any user’s preferred method of interaction.
Not only can PDF files be accessible, PDF has unique strengths when it comes to accessibility. NVDA’s forthcoming support for PDF/UA means that NVDA users with PDF/UA reader software and PDF/UA conforming documents and forms will be assured of a high quality navigation, reading and usage experience, and equality of opportunity for users without disabilities. The PDF Association, Access for All and NV Access expect that assistive technology and document software developers, government agencies and corporations alike will get the message, and begin to demand conformance with the new International Standard for accessible PDF.
The PDF Association is not the first organisation to recognize and support NV Access’s mission to deliver a top-quality and fully capable screen reader free of charge. Adobe Systems has supported NV Access for several years. A member of the PDF Association Council advising NV Access in addition to providing financial support, Adobe Systems believes that the additional support for NV Access provided by the PDF Association’s initiative will accelerate the completion of PDF/UA support and further involvement of the larger community’s interest in PDF/UA.
The Swiss non-profit foundation Access for All has previously created a similar project to fund development of the free PDF Accessibility Checker (PAC)’s support for PDF/UA. Access for All will receive and process all donations and provide project coordination and oversight for the NVDA goes PDF/UA Project.
Duff Johnson, the PDF Association’s Vice Chairman and PDF/UA US Committee Chair since 2005, said, “We at the PDF Association are extremely excited to help NV Access turn the PDF accessibility problem upside down,” he said. “Historically, typical PDF files have offered AT users a poor experience. The rules of accessible PDF were fuzzy enough to stymie development of more and better tools. PDF/UA provides clarity,” Johnson said. “The new standard simplifies the task of ensuring accessibility for consumers, product developers and policy-makers,” he said.
Markus Riesch, Director of the Access for All Foundation, said, “Access for All has recognized PDF/UA as a new paradigm in universal access to electronic content for some time. We are delighted to work with the PDF Association to promote the enhancement of NVDA into the first of many assistive technologies to support this new standard. It’s important to note that when PDF/UA conforming files, readers and assistive technology are all in place, the result enables many types of assistive technologies beyond screen-readers such as magnifiers, alternative input devices and advanced text reflow systems.”
Michael Curran, creator of NVDA, said, “We’re going to show the world that PDF/UA conforming files and PDF viewers together with standards-based assistive technology such as NVDA can offer a superb experience of documents in the PDF format. If two blind guys from Australia can do this what excuse do others have? PDF is a great format for many purposes, but we believe that improved equal access to PDF content means PDF/UA.”
