Overview

EN ISO 9241-129:2010 (ISO 9241-129:2010) provides ergonomic guidance on software individualization within interactive systems. It explains when and how to offer individualization (configuration, customization, adaptivity, profiling, internationalization) so that user interfaces can be tailored to individual users or groups while preserving usability and accessibility. The standard gives design guidance rather than prescribing specific implementation mechanisms and is intended to be used as part of a complete human-centred design approach (not in isolation).

Key topics covered

• Principles and scope
  • Role and limitations of individualization; when individualization is appropriate or inappropriate.
• Usability aspects of individualization
  • Accessibility, controllability, detectability and consistency of individualization features.
  • Ensuring individualization results remain usable and comprehensible.
• Stages of individualization
  • Initiation, deciding actions, and handling changes in system or context.
• Configuration and defaults
  • Guidance on configuration, reconfiguration, guided setup, and sensible default settings.
• User profiles and management
  • Profile creation, automatic profile acquisition, portability and administration of user profiles.
• Individualizing interface components and media
  • Visual, auditory, tactile and temporal aspects of media and how to make individualization usable.
• Individualizing interaction and content
  • Stored interaction sequences, security options, user guidance, on-line help, cultural and linguistic variations.
• Application boundaries
  • Advice on combining software and hardware individualization; conformity considerations and complementary use with ISO 9241-110 and other ISO 9241 parts.

Practical applications and who uses it

This guidance is practical for teams involved in the design, procurement and evaluation of interactive systems where tailoring the interface matters:

• User-interface designers and interaction designers - to plan usable customization and adaptivity.
• Software developers and system integrators - to implement configurable features that are accessible and maintainable.
• Product managers and buyers - to specify individualization requirements in procurements.
• System administrators - to manage profiles and defaults across user groups.
• Usability evaluators and accessibility specialists - to assess conformance and impact on user experience.

Common applications include configurable enterprise software, adaptive consumer applications, assistive-technology features, localized interfaces, and cross-platform systems where individual user preferences must travel with the user.

Related standards

• ISO 9241-110 (Dialogue principles) - use together for general interaction design principles.
• Other ISO 9241 parts on accessibility (e.g., ISO 9241-171), web UIs and human‑centred design (ISO 9241‑210) provide complementary guidance.
