Open Accessibility (A11y) Workgroup

Open A11y Workgroup's Mission Statement

First chartered in 2004 as the Linux Foundation Accessibility Workgroup (LFA), the Open Accessibility (A11y) Group functions today within the Linux Foundation to establish free and open standards that enable comprehensive universal access to various computing platforms, applications, and services. Open A11y makes it easier for developers, ISVs, and distributions to support assistive technologies (AT). Assistive technologies enable individuals to make full use of computer-based technology despite variability in physical or sensory abilities due to illness, aging or disability.

AT enables individuals who are blind or visually impaired to read online text, for example, and provides the means for individuals who do not have the use of their arms and hands to write and correspond. AT also enable individuals who cannot speak or hear to participate on the telephony interfaces of today -- and will support their participation on the multimodal computer interfaces of tomorrow.

IAccessible2 COM proxy stub DLL


We have provided an IAccessible2 COM proxy stub DLL, IAccessible2Proxy.DLL as well as the files necessary for building it from the IAccessible2 IDL file. The proxy DLL is needed so the default marshaler has a description of the IAccessible2 interfaces.


IAccessible2 Development: An Accessibility API that Works for Assistive Technologies and Applications


  • Richard Schwerdtfeger, Distinguished Engineer, IBM
  • Pete Brunet, Senior Software Engineer,IBM
  • Andres Gonzalez, Senior Computer Scientist,Adobe
    • (others to be announced)


After you check the IA2 project files out using BZR, this file can be used to understand how to build the IA2 docs, a merged IDL file, and a zip file containing the docs and IDL files.
