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.
