ISO/IEC 23007-2:2012规定了支持各种高级用户交互设备的高级用户交互界面（AUI）。AUI接口是场景描述和系统资源之间桥梁的一部分。场景描述是由视频、音频、2D图形对象和动画组成的独立的活体实体。通过AUI接口或其他现有接口（如DOM事件），场景描述可以访问感兴趣的系统资源以与用户交互。通常情况下，场景合成由第三方执行并远程部署。

ISO/IEC 23007-2:2012 specifies advanced user interaction interfaces (AUI) to support various advanced user interaction devices. The AUI interface is a part of the bridge between scene descriptions and system resources. A scene description is a self-contained living entity composed of video, audio, 2D graphics objects, and animations. Through the AUI interfaces or other existing interfaces such as DOM events, a scene description accesses interesting system resources to interact with users. In general, a scene composition is conducted by a third party and remotely deployed.
