scope:

This part of ISO/IEC 23007 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.
