Overview - ISO/IEC 30150-1:2022 (AUI - Part 1: Model)
ISO/IEC 30150-1:2022 defines a standardized model for Affective Computing User Interfaces (AUI). The standard provides a systematic, non‑implementation-specific framework for how computing systems can collect, represent, recognize, and present human affects to support adaptive and emotionally aware user interfaces. Annex B lists topics for future AUI standardization and Annex A gives an example application. This part is intended as a reference for developers, designers and standards bodies working on affective computing and human–computer interaction.
Key technical topics and requirements
- Affective characteristics: conceptualizes the range of human affects (including cultural and emotional factors) that influence user behavior and needs, without prescribing specific affect labels.
- General AUI model: four core components - collection, recognition, strategy, and presentation - built on a unifying affect representation.
- AUI-based interaction model: two-loop interaction view (system perspective and user perspective) describing how affect flows between cognition space (user) and information space (system).
- Affect representation:
- Affective characteristic categories - categorical descriptions or combinations of characteristics.
- Dimensional affective space - numeric/ordinal dimensions representing affective states (e.g., values across dimensions to describe recognized affect).
- Affective characteristic data: distinction between static (e.g., single image) and dynamic (e.g., video, voice clip) data; consideration of modalities and media for capture.
- Recognition: modalities for affective characteristic recognition and guidance on multi‑modal fusion and classification processes.
- Strategy: using context of use, inference and decision‑making to determine appropriate affective responses.
- Presentation: modalities and approaches for delivering affective feedback to users.
- Note: The document defines terminology and a conceptual model; it does not specify technical implementations, algorithms, or datasets.
Practical applications and target users
- Practical applications:
- Emotion‑aware user interfaces and assistants
- Personalized and adaptive UX design
- Accessibility enhancements that consider affective needs
- Education technology, healthcare monitoring, customer service bots, and human‑robot interaction where affect sensitivity improves outcomes
- Who should use this standard:
- UI/UX designers and product managers planning affective features
- Software architects and system integrators designing AUI components
- Researchers developing affect recognition and multimodal fusion methods
- Standards developers, accessibility experts and regulators evaluating affective systems
Related standards and guidance
- Part of the ISO/IEC 30150 series - additional parts will address implementation guidance.
- Cross‑references in the standard include ISO 9241‑11 (usability/context of use); consult the ISO online platform for linked terminology and related usability standards.
- For implementation details, practitioners should combine this model with domain‑specific technical standards and best practices for data privacy, ethics and biometric data handling.
