How do we gain insight into how users’ views of documents are shifting? Google Trends is an increasingly interesting source of high-level marketplace data. By aggregating Google’s search data over time, reporting a term’s popularity as compared with all other searches.Participating in the PDF Techniques Accessibility Summit
The PDF Techniques Accessibility Summit’s objective is to establish a broad-based understanding of how PDF files should be tagged for accessibilty. It’s an opportunity to focus on establishing a common set of examples of accessible PDF content, and identify best-practice when tagging difficult cases.Members supporting PDF features!
The typical adoption curve for PDF technologies until approximately 2007 tended to track with that of the original PDF developer. Since then the marketplace has shifted; it’s no longer clear that Adobe drivesPDF feature support worldwide. Accordingly, we are happy to report that adoption of PDF 2.0 continues apace, with new vendors announcing their support every month.Modernizing PDF Techniques for Accessibility
The PDF Techniques Accessibility Summit will identify best-practices in tagging various cases in PDF documents. Questions to be addressed will likely include: the legal ways to tag a nested list, the correct way to caption multiple images, the appropriate way to organize content within headings.Refried PDF
My hospital emailed me a medical records release form as a PDF. They told me to print it, fill it, sign it, scan it and return it to the medical records department, in that order. In 2018? To get the form via email (i.e., electronically), yet be asked to print it? Did the last 20 years just… not mean anything! So I thought I’d be clever. I’d fill it first, THEN print it. Or better yet, never print it, but sign it anyhow, and return it along with a note making the case for improving their workflow. The story continues…
So far, there are no PDF programs or assistive technologies which offer full PDF/UA compliance when providing access to tagged PDF documents. One particularly important reason for this is that the standard is still very new, meaning that corresponding software development has only just begun. Adobe Systems and the not-for-profit Australian organisation NV Access have officially announced their support for PDF/UA and are now working on implementing it in their products.
The first PDF/UA-compliant assistive technology is expected to be the screen reader software Non Visual Desktop Access (NVDA). NVDA was developed by NV Access as a portable, open-source screen reader. It allows blind and partially-sighted users to interact with the Windows operating system and the applications it runs, as well as use PDF documents and the internet, using the synthetic speech function eSpeak, optional Braille output, and other functionality. eSpeak supports more than 40 languages, and other languages and voices can be added using the SAPI interface. The NVDA screen reader can be downloaded for free from the developers website nvda-project.org after which it is easy to install.
At present (as of mid-2013), NVDA is already mostly PDF/UA-compliant. NV Access, the PDF Association and the Swiss-based Access For All foundation are currently working together to further develop the software, to ensure future versions will meet all PDF/UA requirements in full.
Of the PDF software available today, the free Adobe Reader and the paid Adobe Acrobat currently provide the greatest level of compliance with the standard. The current version, Adobe Reader XI, is mostly PDF/UA compliant albeit only under Windows.
