ÖNORM EN ISO 9241-112

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/haptic) typically used in information and communication technology. 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. This document also applies to outputs from interactive systems (such as printed documents, e.g. invoices). The guidance in this document for presenting information is aimed at helping the user to accomplish tasks. This guidance is not aimed at the presentation of information for other reasons (e.g. corporate branding or advertising). It is intended for the following types of users: - user interface designers, who will apply the guidance during the development process; - developers, who will apply the guidance during design and implementation of system functionality; - evaluators, who are responsible for ensuring that products meet the recommendations; - designers of user interface development tools and style guides to be used by user interface designers; - project managers, who are responsible for managing development processes; - buyers, who will reference this document during product procurement.
