ISO/IEC TR 13066-4:20 15概述了Linux/UNIX图形环境辅助功能API的结构和术语。 它将提供以下内容: -API的总体架构和术语的描述； -除了ISO/IEC 13066中的内容和API的使用之外，还需要进一步的介绍性说明？1:20 11，附件A； -主要物业概览，包括 -用户界面元素， -如何获得和设置焦点，以及 -API中的通信机制； -对API的设计考虑的讨论(例如，指向与使用API相关的可访问性指南的外部信息源的指针)； -关于扩展API的信息（以及在适当的情况下）； -介绍API的编程接口（包括指向外部信息源的指针）。它将提供这些信息作为Java API的介绍，以帮助执行以下操作: -创建定制控件和/或与之接口的IT系统级开发人员； -AT开发人员参与编程“硬件到软件”和“软件到软件”交互。

ISO/IEC TR 13066-4:2015 provides an overview to the structure and terminology of the Linux/UNIX graphical environments accessibility API.
It will provide the following:
- 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 ISO/IEC 13066？1:2011, Annex A;
- an overview of the main properties, including
    - of user interface elements,
    - of how to get and set focus, and
    - 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 will provide this information as an introduction to the Java API to assist the following:
- 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.
