  2. 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.

  3. 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.

  4. ISO TS 16071 Ergonomics of Human-System Interaction – Guidance on Software Accessibility • Software accessibility for people with disabilities • Disabilities: • - blindness, low vision, color vision impairments • - deafness, hearing deficits • - motor impairments, limited mobility • - cognitive disabilities?, mental disorders? • - elderly?, temporary disabilities?, disabilities caused by the environment? • - multiple disabilities?

  5. Application area: - software for business and personal use - WWW? - Multimedia? - Information kiosks? Potential users: - software developers - software purchasers and vendors - users with disabilities - standardisers ISO TS 16071 Ergonomics of Human-System Interaction – Guidance on Software Accessibility

  6. ISO TS 16071 Ergonomics of Human-System Interaction – Guidance on Software Accessibility • ANSI HFES 200 “Ergonomic requirements for software user interfaces” (Accessibility section) • “Nordic Guidelines for Computer Accessibility” • Ministry of international trade and industry, Japan. “Accessibility guidelines for information processing equipment for persons with disabilities” • WAI (Web Accessibility Initiative (W3C Accessibility Group) • IEC TC 100 “Guidelines for the user interface in multimedia equipment for general purpose use”

  7. 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)

  8. 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))

  9. ISO TS 16071 Ergonomics of Human-System Interaction – Guidance on Software Accessibility • Measurable accessibility • Accessibility1=f(user1, task1, context1, product1) • Accessibility2=f(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

  11. ISO-standardisation in which CID participates WG5 (Software ergonomics and HC dialogues) Activities: ISO 9241 - Software ergonomics for office work with visual display terminals ISO 14073 - Multimedia user interface design ISO 16071 - Guidance on accessibility of human-computer interfaces WG6 (Human centred design process) Activities: ISO 13407 - Human centred design process of interactive systems ISO 16982 - Usability methods supporting human centred design ISO 18529 - Human centred lifecycle process descriptions (Usability maturity model)

  13. 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 6385 - Ergonomic principles in the design of work system

  14. ISO 9241 Ergonomic requirements for office work with visual display terminals (VDTs) • Part 1 - General introduction (IS/EN) • Part 2 - Guidance on task requirements (IS/EN) • Part 3 - Visual display requirements (IS/EN) • Part 4 - Keyboard requirements (IS/EN) • Part 5 - Workstation layout and postural requirements (IS/EN) • Part 6 - Environmental requirements (IS/EN) • Part 7 - Display requirements with reflections (IS/EN) • Part 8 - Requirements for displayed colours (IS/EN) • Part 9 - Requirements for non keyboard input devices (IS/EN) • Part 10 - Dialogue principles (IS/EN)

  15. ISO 9241 Ergonomic requirements for office work with visual display terminals (VDTs) • Part 11 - Guidance on usability specification and measures (IS/EN) • Part 12 - Presentation of information (IS/EN) • Part 13 - User guidance (IS/EN, awaiting pubication) • Part 14 - Menu dialogues (IS/EN) • Part 15 - Command dialogues (IS/EN) • Part 16 - Direct manipulation dialogues (IS/EN) • Part 17 - Form filling dialogues (IS/EN) • Amendment to part 1 - Description and application of the software parts (Part 10 through Part 17)

  16. Definition 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 9241 Part 11 Guidance on Usability ISO 9241 Ergonomic requirements for office work with visual display terminals (VDTs)

  17. ISO 14915 Multimedia User Interface Design - Software Ergonomic Reqs. • Ergonomic requirements for human-centred multimedia interfaces • Scope • Development of an ergonomic standard for multimedia information presentation and multimedia/multimodal interaction which will be applicable during software design

  18. ISO 14915 Multimedia User Interface Design - Software Ergonomic Reqs. Purpose • Multimedia user interfaces are growing • So far, multimedia user interfaces have been mainly technology driven • Therefore, the standard should provide recommendations on design, use, combination and how to interact with various media.

  19. ISO 14915 Multimedia User Interface Design - Software Ergonomic Reqs. • Part 1 - Introduction and Framework • Part 2 - Multimedia Control and Navigation • Part 3 - Selection of Media and Media Combination • Part 4 - Domain Specific Multimedia Aspects

  20. ISO 13407 Human Centred Design Process for Interactive Systems

  21. Ergonomics of human-system interaction - Human-centred lifecycle process descriptions • Intended user: • those who are involved in the design, use and assessment of system, hardware and software lifecycle processes. • Scope • Contains and describes a formalised model of the human-centred processes described in ISO 13407. It is intended to be used in the specification, assessment and improvement of the human-centred processes in system development and operation.

  22. Ergonomics of human-system interaction - Human-centred lifecycle process descriptions • The model consists of seven sets of best practice: • Ensure HCD content in system strategy • Plan and manage the HCD process • Specify stakeholder and organisational req. • Understand and specify the context of use • Produce design solutions • Evaluate designs against requirements. • Intoduce and operate the system
