Overview
ISO/IEC TR 30150-2:2024 is a Technical Report from ISO/IEC JTC 1/SC 35 that defines the affective characteristics relevant to affective computing user interfaces (AUI). The document identifies, organizes and explains affective properties - universal, cultural, individual and situational - and describes selection criteria and methods to identify or apply them. It is intended for developers and designers of AUI who need to meet users’ affective needs. The report does not specify implementation or algorithms for emotion recognition or synthesis.
Key topics
- Organization of affective characteristics: classification into Universal, Cultural, Individual and Situational types to guide design decisions.
- Universal characteristics: human needs (Maslow-inspired hierarchy - physiological, safety, belonging, esteem, self‑actualization) and implications for application design.
- Cultural characteristics: how culture shapes beliefs, behaviors and group traits, and how interfaces should recognize cultural effects and trade-offs.
- Individual characteristics: personality, attitudes, beliefs, achievement motivation and risk taking/aversion as factors that make each user unique.
- Situational characteristics: transient nature of emotions, relationship to satisfaction and UX, and the role of context-of-use.
- Identification methods: non-normative guidance on how to identify affective characteristics, including physiological signals, direct questions, inference from user customizations, actions, vocabulary, and associative techniques.
- Affective vs cognitive domains: relationship and distinctions (see informative Annex A).
- Terminology: definitions for affective characteristic, affective, satisfaction and cognition (references include ISO 9241-11:2018 and ISO 21801-1:2020).
Applications and who should use it
- AUI developers and software engineers designing emotion-aware interfaces and adaptive experiences.
- UX/UI designers and product managers aiming to incorporate affect-sensitive features while respecting cultural and individual differences.
- Accessibility specialists ensuring affective adaptations do not reduce usability for diverse users.
- Researchers and HCI practitioners studying affective interactions, user satisfaction and context-driven emotion modeling.
- Systems integrators and stakeholders planning affective components in healthcare, education, assistive technologies, customer service, automotive UX and consumer devices.
Practical uses include selecting which affective attributes to monitor or respect in a product, designing consent and privacy-aware data collection strategies for affective signals, and informing user-testing and localization strategies.
