Jan Gulliksen, Januari 2001 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.
Jan Gulliksen, Januari 2001 ISO TS Ergonomics of Human- System Interaction – Guidance on Software Accessibility Usable products (according to ISO ) 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.

Jan Gulliksen, Januari 2001 ISO TS 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)
Jan Gulliksen, Januari 2001 ISO TS 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. (W 3 C 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))

Jan Gulliksen, Januari 2001 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 ISO Ergonomic principles in the design of work system
