Overview
IEC TR 61997:2001 - Guidelines for the user interface in multimedia equipment for general purpose use provides non‑mandatory, practical guidance for designing user interfaces of multimedia equipment intended for the general public. The report addresses information and communications equipment, audio‑video systems, home appliances and similar devices used by people with no special training (including children and senior citizens). It focuses on usability issues specific to multimedia products and complements detailed ergonomic standards rather than replacing them.
Key topics
- MAQ reference model: a three‑dimensional model classifying interfaces by Media (visual, audio, mechanical, other), Abstraction (lexical, syntax, semantics layers), and QOI (Quality Of Interfaces: minimum, standard, excellent).
- Interaction model: concepts such as invitation, operation, feedback and the roles of user, equipment and designer to structure human‑machine interaction.
- Quality of Interface (QOI): definitions and function levels that guide how interfaces should support visibility, ease of operation and user confidence.
- Essential QOI criteria: practical criteria including easiness, efficiency, consistency, perceiver (cognitive fit), certainty, relief & comfort, personal & social conditions, accessibility, and safety & health.
- Media‑specific guidance (Annex A): recommendations for media selection, mechanical/graphical user interfaces and auditory interfaces - i.e., how to use displays, controls, sound and tactile elements effectively.
- Scope limits: numerical ergonomics (e.g., switch sizes, spacing, fonts) are intentionally excluded and referenced to existing ergonomic standards.
Applications and who should use it
IEC TR 61997 is aimed at:
- UI/UX designers, product designers and engineers creating consumer multimedia devices.
- Product managers and system architects responsible for human‑device interaction.
- Manufacturers of AV systems, information/communication equipment, home automation and automotive infotainment.
- Standards developers and usability professionals seeking harmonized guidance when integrating multimedia feedback channels.
Practical benefits:
- Improved usability and accessibility for untrained users.
- Reduced user errors and anxiety through clearer invitation/feedback patterns.
- Better alignment with human‑centered design processes for multimedia products.
