Ergonomics of human-system interaction - Part 171 : guidance on software accessibility

ISO 9241-171:2008 provides ergonomics guidance and specifications for the design of accessible software for use at work, in the home, in education and in public places. It covers issues associated with designing accessible software for people with the widest range of physical, sensory and cognitive abilities, including those who are temporarily disabled, and the elderly. It addresses software considerations for accessibility that complement general design for usability as addressed by ISO 9241-110, ISO 9241-11 to ISO 9241-17, ISO 14915 and ISO 13407.ISO 9241-171:2008 is applicable to the accessibility of interactive systems. It addresses a wide range of software (e.g. office, Web, learning support and library systems).It promotes the increased usability of systems for a wider range of users. While it does not cover the behaviour of, or requirements for, assistive technologies (including assistive software), it does address the use of assistive technologies as an integrated component of interactive systems.It is intended for use by those responsible for the specification, design, development, evaluation and procurement of software platforms and software applications.

It promotes the increased usability of systems for a wider range of users. While it does not cover the behaviour of, or requirements for, assistive technologies (including assistive software), it does address the use of assistive technologies as an integrated component of interactive systems.

It is intended for use by those responsible for the specification, design, development, evaluation and procurement of software platforms and software applications.

Ergonomics of human-system interaction - Guidance on accessibility for human-computer interfaces

ISO/TS 16071:2002 provides guidance on the design of accessible (work, home, education) software. It covers issues associated with designing accessible software for people with the widest range of visual, hearing, motor and cognitive abilities, including those who are elderly and temporarily disabled. ISO/TS 16071:2002 addresses software considerations for accessibility that complement general design for usability covered by ISO 9241-10 to ISO 9241-17 and ISO 13407. ISO/TS 16071:2002 addresses the accessibility of interactive systems. It addresses a wide range of solutions, including office applications, web pages and multimedia. It does not provide recommendations for the design of hardware. ISO/TS 16071:2002 promotes increased usability of systems in combination with assistive technologies, when they are required. It does not cover the behaviour or requirements of assistive technologies themselves (including assistive software).

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
