Universal design
Universal design is the design of buildings, products or environments to make them accessible to all people, regardless of age, disability or other factors.
The term "universal design" was coined by the architect Ronald Mace to describe the concept of designing all products and the built environment to be aesthetic and usable to the greatest extent possible by everyone, regardless of their age, ability, or status in life. However, it was the work of Selwyn Goldsmith, author of Designing for the Disabled, who really pioneered the concept of free access for people with disabilities. His most significant achievement was the creation of the dropped curb – now a standard feature of the built environment.
Universal design emerged from slightly earlier barrier-free concepts, the broader accessibility movement, and adaptive and assistive technology and also seeks to blend aesthetics into these core considerations. As life expectancy rises and modern medicine increases the survival rate of those with significant injuries, illnesses, and birth defects, there is a growing interest in universal design. There are many industries in which universal design is having strong market penetration but there are many others in which it has not yet been adopted to any great extent. Universal design is also being applied to the design of technology, instruction, services, and other products and environments.
Curb cuts or sidewalk ramps, essential for people in wheelchairs but also used by all, are a common example. Color-contrast dishware with steep sides that assists those with visual or dexterity problems are another. There are also cabinets with pull-out shelves, kitchen counters at several heights to accommodate different tasks and postures, and, amidst many of the world's public transit systems, low-floor buses that "kneel" and/or are equipped with ramps rather than on-board lifts.
Principles
The Center for Universal Design at North Carolina State University expounds the following principles:- Equitable use
- Flexibility in use
- Simple and intuitive
- Perceptible information
- Tolerance for error
- Low physical effort
- Size and space for approach and use
These principles are broader than those of accessible design and barrier-free design.
Goals of universal design
In 2012, the Center for Inclusive Design and Environmental Access at the University at Buffalo expanded definition of the principles of universal design to include social participation and health and wellness. Rooted in evidence based design, the 8 goals of universal design were also developed.- Body Fit
- Comfort
- Awareness
- Understanding
- Wellness
- Social Integration
- Personalization
- Cultural Appropriateness
Examples
- Smooth, ground level entrances without stairs
- Surface textures that require low force to traverse on level, less than 5 pounds force per 120 pounds rolling force
- Surfaces that are stable, firm, and slip resistant per ASTM 2047
- Wide interior doors, hallways, and alcoves with 60" × 60" turning space at doors and dead-ends
- Functional clearances for approach and use of elements and components
- Lever handles for opening doors rather than twisting knobs
- Single-hand operation with closed fist for operable components including fire alarm pull stations
- Components that do not require tight grasping, pinching or twisting of the wrist
- Components that require less than 5 pounds of force to operate
- Light switches with large flat panels rather than small toggle switches
- Buttons and other controls that can be distinguished by touch
- Bright and appropriate lighting, particularly task lighting
- Auditory output redundant with information on visual displays
- Visual output redundant with information in auditory output
- Contrast controls on visual output
- Use of meaningful icons with text labels
- Clear lines of sight to reduce dependence on sound
- Volume controls on auditory output
- Speed controls on auditory output
- Choice of language on speech output
- Ramp access in swimming pools
- Closed captioning on television networks
- Signs with light-on-dark visual contrast
- Web pages that provide alternative text to describe images
- Instruction that presents material both orally and visually
- Labels in large print on equipment control buttons
- A museum that allows visitors to choose to listen to or read descriptions
Design standards
Another comprehensive publication by the Royal Institute of British Architects published three editions 1963, 1967, 1976 and 1997 of Designing for the Disabled by Selwyn Goldsmith UK. These publications contain valuable empirical data and studies of individuals with disabilities. Both standards are excellent resources for the designer and builder.
Disability ergonomics should be taught to designers, engineers, non-profits executives to further the understanding of what makes an environment wholly tenable and functional for individuals with disabilities.
In October 2003, representatives from China, Japan, and South Korea met in Beijing and agreed to set up a committee to define common design standards for a wide range of products and services that are easy to understand and use. Their goal is to publish a standard in 2004 which covers, among other areas, standards on containers and wrappings of household goods, and standardization of signs for public facilities, a subject which was of particular interest to China as it prepared to host the 2008 Summer Olympics.
The International Organization for Standardization, the European Committee for Electrotechnical Standardization, and the International Electrotechnical Commission have developed:
- CEN/CENELEC Guide 6. Guidelines for standards developers to address the needs of older persons and persons with disabilities
- ISO 20282-1:2006 - Ease of operation of everyday products — Part 1: Context of use and user characteristics
- ISO/TS 20282-2:2013 - Usability of consumer products and products for public use—Part 2: Summative test method, published 1 August 2013.
Design for All
Background
Design for All has been highlighted in Europe by the European Commission in seeking a more user-friendly society in Europe. Design for All is about ensuring that environments, products, services and interfaces work for people of all ages and abilities in different situations and under various circumstances.Design for All has become a mainstream issue because of the aging of the population and its increasingly multi-ethnic composition. It follows a market approach and can reach out to a broader market. Easy-to-use, accessible, affordable products and services improve the quality of life of all citizens. Design for All permits access to the built environment, access to services and user-friendly products which are not just a quality factor but a necessity for many aging or disabled persons. Including Design for All early in the design process is more cost-effective than making alterations after solutions are already in the market. This is best achieved by identifying and involving users in the decision-making processes that lead to drawing up the design brief and educating public and private sector decision-makers about the benefits to be gained from making coherent use of Design in a wide range of socio-economic situations.
Examples
The following examples of Designs for All were presented in the book Diseños para todos/Designs for All published in 2008 by Optimastudio with the support of Spain's Ministry of Education, Social Affairs and Sports and CEAPAT:- Audiobook
- Automatic door
- Electric Toothbrush
- Flexible drinking straw
- Low-floor bus
- Q-Drums
- Tactile paving
- Trolley case
- Velcro
- Washlet
- Wireless remote controlled power sockets
- Wireless remote controlled window shades
In information and communication technology (ICT)
European DfA organizational networks
In Europe, people have joined in networks to promote and develop Design for All:- The European Design for All eAccessibility Network was launched under the lead of the European Commission and the European Member States in 2002. It fosters Design for All for eInclusion, that is, creating an information society for all. It has national contact centres in almost all EU countries and more than 160 network members in national networks.
- EIDD - Design for All Europe is a NGO and a 100% self-financed European organization that covers the entire area of theory and practice of Design for All, from the built environment and tangible products to communication, service and system design. Originally set up in 1993 as the European Institute for Design and Disability, to enhance the quality of life through Design for All, it changed its name in 2006 to bring it into line with its core business. EIDD - Design for All Europe disseminates the application of Design for All to business and administration communities previously unaware of its benefits and currently has 31 member organizations in 20 European countries.
- EuCAN - The European Concept for Accessibility Network started in 1984 as an open network of experts and advocates from all over Europe in order to promote and support the Design for All approach. The coordination work of EuCAN and the functioning of the network are mainly voluntary work. In 1999 the Luxembourg Disability Information and Meeting Centre took over the coordination of the steering group, together with the implicit responsibility for the follow-up of the European Concept for Accessibility. The EuCAN publications - like ECA - aim to provide practical guidance. They are neither academic nor policy documents.
The "Barrier-Free" concept
Freeing a building of barriers means:
- Recognizing the features that could form barriers for some people
- Thinking inclusively about the whole range of impairments
- Reviewing everything - from structure to smallest detail
- Seeking feedback from users and learning from mistakes
An example of a country that has sought to implement barrier-free accessibility in housing estates is Singapore. Within five years, all public housing estates in the country, all of 7,800 blocks of apartments, have benefited from the program.
