Information technology. Interoperability with Assistive Technology (AT). IAccessible2 accessibility application programming interface (API) | Status: Confirmed, Current

1 Scope This part of ISO/IEC 13066 provides an overview to the structure and terminology of the IAccessible2 accessibility API. It provides:

• — a description of the overall architecture and terminology of the API;
• — further introductory explanations regarding the content and use of the API beyond those found in Annex A of ISO/IEC 13066-1;
• — an overview of the main properties, including:
  • — of user interface elements,
  • — of how to get and set focus,
  • — of communication mechanisms in the API;
• — a discussion of design considerations for the API (e.g. pointers to external sources of information on accessibility guidance related to using the API);
• — information on extending the API (and where this is appropriate);
• — an introduction to the programming interface of the API (including pointers to external sources of information).

It provides this information as an introduction to the IAccessible2 API to assist:

• — IT system level developers who create custom controls and/or interface to them;
• — AT developers involved in programming "hardware to software" and "software to software" interactions.
