This document establishes ergonomic design principles for interactive systems related to the software-controlled presentation of information by user interfaces. It applies to the three main modalities (visual, auditory, tactile or haptic) typically used in information and communication technology (ICT). These principles apply to the perception and understanding of presented information. These principles are applicable in the analysis, design and evaluation of interactive systems. This document also provides recommendations corresponding to the principles. The recommendations for each of the principles are not exhaustive and are not necessarily independent from one another. While this document is applicable to all types of interactive systems, it does not cover the specifics of particular application domains which require context-specific recommendations. This document also applies to outputs from interactive systems (such as printed documents and document exports in common computer formats, e.g. pdf, text and tabular formats).
