Overview

EN ISO 9241-20:2021 - "Ergonomics of human‑system interaction - Part 20: An ergonomic approach to accessibility" - introduces how accessibility fits into the ISO 9241 ergonomics series. The 2021 edition updates and replaces earlier versions and positions accessibility as an integral part of human‑centred design for interactive systems, referencing relevant ISO 9241 parts and other accessibility standards.

Key topics

Role of accessibility in human‑system interaction: explains why accessibility matters for usability and universal access.

Ergonomic principles mapped to accessibility: discusses principles from ISO 9241 parts (notably ISO 9241‑171 and ISO 9241‑110) such as suitability for the widest range of use, equitable use, robustness, self‑descriptiveness, learnability, controllability, use error robustness, and approachability.

Human‑centred design activities: aligns the ISO 9241‑210 user‑centred design process with accessibility‑focused activities - scoping, identifying users and context of use, requirements specification, producing design solutions, evaluation, iteration and conformity assessment.

Practical guidance and references: points to specific ISO 9241 parts (e.g., 110, 112, 171, 400, 500, 210) and other international accessibility guidance rather than prescribing new technical requirements.

Evaluation and conformity: stresses evaluation from the user’s perspective and references methods for assessing accessibility as part of the design lifecycle.

Practical applications

Integrating accessibility requirements into product development (software, web, AT, terminals, IT peripherals).

Using ergonomic principles to derive accessibility features and user requirements.

Structuring accessibility‑focused user research, prototyping and usability testing.

Informing procurement, compliance checks and internal accessibility policies by linking user‑centred processes to recognized standards.

Who should use this standard

UX/UI designers and accessibility specialists who need to adopt ergonomic principles for accessible interfaces.

Ergonomists and human factors professionals applying ISO 9241 guidance.

Product managers, developers and QA teams integrating accessibility into Agile or V‑model workflows.

Standards writers, auditors and procurement officers who map accessibility requirements to international standards and conformity assessments.

Related standards

EN ISO 9241‑20:2021 is part of the ISO 9241 series and cross‑references parts such as ISO 9241‑110, ISO 9241‑171, ISO 9241‑210 and other specialized parts addressing interaction, visual displays, input devices and evaluation methods. Use this part as a roadmap to locate detailed technical guidance across the ISO 9241 family.

Keywords: ISO 9241-20, ergonomic approach to accessibility, human‑system interaction, accessibility standards, human‑centred design, usability, accessibility in interactive systems.
