This document provides guidance on aspects of the design of human-system interaction, including conceptual design, user-system interaction design, user interface design and navigation design for interactive systems. This document applies to all design and development approaches and methodologies, including human-centred design, object-oriented, waterfall, human factors integration (HFI), agile and rapid development. 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 the 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.
