NYS Technology Standard S04-001 • Standard 14: Downloadable/Embedded Objects • 14.1 When downloadable documents [e.g., word processing documents, spreadsheets, Portable Document Format (PDF), java applets] are used, a link to accessible HTML or text version(s) will be made available. Northeast ADA & IT Center
Why require accessible HTML or text? • Requirements for individuals using screen readers • Only 2 screen readers can read PDF format • JAWS ($900 - $1100 + maintenance agreement) • Window Eyes ($800) • Must have the latest versions of Adobe Reader 6.01 (full version not basic version) • Wide range of users & browsing environments • Slow connection, older equipment, WebTV, cell phones, PDAs Northeast ADA & IT Center
Why require accessible HTML or text? • Authoring requirements • PDF files must be structured and tagged using Acrobat 5+ (full version) • MS Word 2000+ (only one to preserve structure when creating PDF file) • No assurances that final PDF file will be completely accessible depending on complexity of document • Many existing PDF files are not accessible and would require much work to convert to accessible PDF Northeast ADA & IT Center
Adobe Read-Out-Loud Feature Excerpted from Adobe Reader Help: Note: The Read-Out-Loud feature can read the text of a PDF file out loud, but is not a screen reader. Some systems may not support this feature. To read a document out loud: 1. Open the Adobe PDF document you want to read, and then navigate to the page on which you want to start reading. 2. Choose View > Read Out Loud > Read This Page Only or Read To End Of Document. • Does not have the full functionality of a screen reader • Still requires the document to be created with some degree of accessibility; especially complex documents Northeast ADA & IT Center
