Advanced Topics in HCIT Introduction to Universal Design Bláithín Gallagher PhD Marie Curie Research Fellow Advanced Research Methods for HCIT © 2012 Department of Computer Science It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.* Albert Einstein Everything should be made as simple as possible. But no simpler. *from On the Method of Theoretical Physics, p. 183. The Herbert Spencer Lecture, delivered at Oxford (10 June 1933) Advanced Topics HCIT © 2013 Department of Computer Science What is Universal? Today, more than ever before, life must be characterized by a sense of Universal responsibility, not only nation to nation and human to human, but also human to other forms of life. Dalai Lama Universal:Adjective: .Of or pertaining to the universe; extending to, including, or affecting, the whole number, quantity, or space; unlimited; general; all-reaching; all-pervading; as, universal ruin; universal good; universal benevolence or benefice. Adapted or adaptable to all or to various uses, shapes, sizes, etc. Noun: A person or thing having universal effect, currency, or application, in particular. Advanced Topics HCIT © 2013 Department of Computer Science What is Design? “Design is what links creativity and innovation. It shapes ideas to become practical and attractive propositions for users or customers. Design may be described as creativity deployed to a specific end.’Design is powerful and profoundly influences our daily lives and our sense of confidence, comfort, and control.” Sir George Cox DESIGN:Noun - A plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made. Verb - Decide upon the look and functioning of (a building, garment, or other object), typically by making a detailed drawing of it. Advanced Topics HCIT © 2013 Department of Computer Science Advanced Topics HCIT © 2013 Department of Computer Science Terminology Barrier-free design: concerned with Access focus on disability and accommodating people with disabilities in the environment. e,g. Removing architectural barriers Assistive technology: focus on compensating an individual function with a disability. Can range from eye glasses to a screen reader Universal design takes into account all potential users not just user with disabilities Advanced Topics HCIT © 2013 Department of Computer Science Definitions of Universal Design Universal Design is the design of products and environments to be usable by everyone, to the greatest extent possible, without the need for adaptation or specialized design Ron Mace Universal Design is a framework for the design of places, things, information, communication and policy to be usable by the widest range of people operating in the widest range of situations without special or separate design. Most simply, Universal Design is humancentered design of everything with everyone in mind. The Institute for Human Centered Design Advanced Topics HCIT © 2013 Department of Computer Science Definitions of Universal Design “Universal Design ("UD") increases usability, safety and health of environments, products and systems in response to the diversity of people and abilities. With attention focused on the changing demographics, differences in functional ability and preferences are part of everyday life experience. UD represents a paradigm for design of the built environment and products to address this diversity and increase use by all by introducing flexibility, choice and accommodating features to the physical world and business practices. The Global Universal Design Commission Advanced Topics HCIT © 2013 Department of Computer Science Definitions of Universal Design Universal design makes things more accessible, safer, and convenient for everyone. Also called “Design for All” or “Inclusive Design,” it is a philosophy that can be applied to policy, design and other practices to make products, environments and systems function better for a wider range of people. It developed in response to the diversity of human populations, their abilities and their needs. The Center for Inclusive Design and Environmental Access (IDeA Center) Advanced Topics HCIT © 2013 Department of Computer Science Definitions of Universal Design UN Convention on the Rights of Persons with Disabilities Article 2 – Definitions: ““Universal design” means the design of products, environments, programmes and services to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design.” ““Universal design” shall not exclude assistive devices for particular groups of persons with disabilities where this is needed.” Advanced Topics HCIT © 2013 Department of Computer Science Design Powerful Influential Impact Social, Economic, Cultural, Environmental Acknowledge Diversity of the human ability What is normal?

Advanced Topics HCIT © 2013 Department of Computer Science Advanced Topics HCIT © 2013 Department of Computer Science Myths One product fits all Only achieved by specialist designers only Can be applied at the end of the design process A synonym for compliance with accessible design standards Only disabled and elderly people benefit Leads to aesthetically unattractive products Advanced Topics HCIT © 2013 Department of Computer Science Facts about Universal Design Aims to improve the original design concept Maximise accessibility & usability of a product Aspires to benefit every member of the population Positive user experience of simple and intuitive design. Incorporates a user centered approach Requires an awareness and appreciation of the diverse abilities of people. It is a process not a product Advanced Topics HCIT © 2013 Department of Computer Science Universal design is... Not necessarily a specialist subject. Not a list of specifications; Not an add-on design approach. Not just about 'one size fits all' Not a replacement to the design of products targeted at specific markets Not just a synonym for `'accessibility” Advanced Topics HCIT © 2013 Department of Computer Science Policy UN Convention on the Rights of Persons with Disabilities – General Obligations: State Parties are “to undertake or promote research and development of universally designed goods, services, equipment and facilities ……………… to promote their availability and use, and to promote universal design in the development of standards and guidelines.” Advanced Topics HCIT © 2013 Department of Computer Science Policy Council of Europe Resolution 2001: On the incorporation of Universal Design into the design curriculum Draft Resolution 2007: On achieving full participation through Universal Design Disability Action Plan: Universal Design identified as “vital element of the implementation strategy” with specific reference to curriculum, ICT, built environment, products and services.

Robert Fabricant Advanced Topics HCIT © 2013 Department of Computer Science Summary Approach to design that aims to ensure that the object under design can be used by virtually everyone, regardless of their level of ability or disability. What is “normal”? Continuum of ability When more of us have a “disability” than not, universal design will indeed become universal.
