1 Scope
This document specifies requirements and provides recommendations for the selection,
usage and dependencies of visual user-interface elements and their application. This document is concerned with visual software components
of interactive systems to make human-system interaction usable.
This document is applicable regardless of a fixed, portable or mobile interactive
system, or cross-device use.
It does not provide detailed coverage of the methods and techniques required for design
of visual user-interface elements. This document does not address implementation (e.g. graphical design of elements)
and interaction details for specific input methods or technologies. It does not cover
decorative user-interface elements that are intended to address solely aesthetic (hedonic) qualities in the user interface
e.g. background images.
