Over a billion people around the world have some form of disability, so ensuring products, services and environments are accessible to everyone is fundamental to human rights. Standards have a strong role to play in that, which is why ISO developed ISO/IEC Guide 71, Guide for addressing accessibility in standards.
Aimed at standards developers, Guide 71 helps ensure that accessibility issues are considered when developing or revising standards. Since a key element of accessibility is human ergonomics, ISO also has guidance on ergonomics data to support users of Guide 71, and it has just been updated.
ISO/TR 22411, Ergonomics data for use in the application of ISO/IEC Guide 71:2014, helps standards developers to understand human characteristics and capabilities of persons with disabilities and older persons.
This technical report provides quantitative data and knowledge as well as context-specific and task-specific data, all being based on ergonomics research. The data focuses on the effects of ageing and/or consequences of various types of human sensory, physical and cognitive disabilities.
While primarily aimed at standards developers, ISO/TR 22411 can also be used by ergonomists and designers to support the development of more accessible products, systems, services, environments and facilities.
The technical report has just been updated with new or more elaborate data that is now available. What’s more, this new edition includes the provision, in an annex, of alternative text for figures and tables that makes them more accessible to visually impaired readers.
