Interntional Organization for Standardization
(ISO) Established 1947 The mission is to promote
the development of standardisation and related
activities in the world with a view to
facilitating the international exchange of goods
and services and to developing cooperation in the
spheres of intellectual, scientific,
technological and economic activity. Some 100
countries An international standard is a
resulting agreement.

ISO TS 16071 Ergonomics of Human-System
Interaction Guidance on Software Accessibility

• Usable products (according to ISO 9241-11) are
  not necessarily usable for disabled users.
• Purpose and Justification
• - Increase efficiency, effectiveness and
  satisfaction for those with disabilities
• - Reduce the need for add-on assistive
  technologies
• - Accomodation to disabilities without increased
  costs
• - Making applications accessible for disabled
  users should benefit able users as well.

ISO TS 16071 Ergonomics of Human-System
Interaction Guidance on Software Accessibility

• Definitions of Accessibility
• The usability of a product, service, environment
  or facility by people with the widest range of
  capabilities. (ISO TS 16071)
• Definitions of Usability
• The extent to which a product can be used by
  specified users, to achieve specified goals, with
  effectiveness, efficiency and satisfaction, in a
  specified context of use. (ISO IS 9241 Part 11
  Guidance on usability)

ISO TS 16071 Ergonomics of Human-System
Interaction Guidance on Software Accessibility

• Definitions of Accessibility
• Content is accessible when it may be used by
  someone with a disability. (W3C WAI guidelines,
  1.0)
• The set of properties that allows a product,
  service or facility to be used by people with a
  wide range of capabilities, either directly or in
  conjunction with assistive technologies. Although
  accessibility typically addresses users who
  have a disability, the concept is not limited to
  disability issues. (ANSI HFES 200 (draft))

ISO TS 16071 Ergonomics of Human-System
Interaction Guidance on Software Accessibility

• Measurable accessibility
• Accessibility1f(user1, task1, context1,
  product1)
• Accessibility2f(user1, task1, context1,
  product2)
• Rationale and benefits
• Identify aspects of accessibility
• Measure performance (effectiveness and
  efficiency) and satisfaction
• Compare relative accessibility of products
• Make accessibility a part of a quality plan

10
ISO TS 16071 Ergonomics of Human-System
Interaction Guidance on Software Accessibility

• Future work on accessibility
• New Work Item proposal converting TS 16071 into
  an IS
• SIG at UAHCI 2001 to gather more guidelines
• Restructuring 9241 and other standards to make
  16071 an integral part
• New media for communicating standards
  interactively

ISO 6385 - Ergonomic principles in the design of
work system

• Definition of ergonomics
• Ergonomics produces and integrates knowledge from
  the human and technology sciences to match jobs,
  systems, products and environments to the
  physical and mental abilities and limitations of
  people. In doing so it seeks to safeguard safety,
  health and well-being whilst optimising
  efficiency and performance
