What is Universal Design?

I was working on an item on Universal Design and realized that I hadn’t actually defined what I was talking about. So from the man who coined the phrase:

“Universal design is the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design.”
— Ron Mace, founder and program director of The Center for Universal Design

Universal design has its roots in demographic, legislative, economic, and social changes among older adults and people with disabilities after World War II.

Here are some general principles for the evaluation of universal design from the Center for Universal Design. These were drafted in 1997 and refer to design in the physical world, though could be applied broadly to electronic interface design.

1. Equitable Use
   The design is useful and marketable to people with diverse abilities.
   1. Provide the same means of use for all users: identical whenever possible; equivalent when not.
   2. Avoid segregating or stigmatizing any users.
   3. Provisions for privacy, security, and safety should be equally available to all users.
   4. Make the design appealing to all users.
      
      
2. Flexibility in Use
   The design accommodates a wide range of individual preferences and abilities.
   1. Provide choice in methods of use.
   2. Accommodate right- or left-handed access and use.
   3. Facilitate the user’s accuracy and precision.
   4. Provide adaptability to the user’s pace.
      
      
3. Simple and Intuitive Use
   Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
   1. Eliminate unnecessary complexity.
   2. Be consistent with user expectations and intuition.
   3. Accommodate a wide range of literacy and language skills.
   4. Arrange information consistent with its importance.
   5. Provide effective prompting and feedback during and after task completion.
      
      
4. Perceptible Information
   The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
   1. Use different modes (pictorial, verbal, tactile) for redundant presentation of essential information.
   2. Provide adequate contrast between essential information and its surroundings.
   3. Maximize “legibility” of essential information.
   4. Differentiate elements in ways that can be described (i.e., make it easy to give instructions or directions).
   5. Provide compatibility with a variety of techniques or devices used by people with sensory limitations.
      
      
5. Tolerance for Error
   The design minimizes hazards and the adverse consequences of accidental or unintended actions.
   1. Arrange elements to minimize hazards and errors: most used elements, most accessible; hazardous elements eliminated, isolated, or shielded.
   2. Provide warnings of hazards and errors.
   3. Provide fail safe features.
   4. Discourage unconscious action in tasks that require vigilance.
      
      
6. Low Physical Effort
   The design can be used efficiently and comfortably and with a minimum of fatigue.
   1. Allow user to maintain a neutral body position.
   2. Use reasonable operating forces.
   3. Minimize repetitive actions.
   4. Minimize sustained physical effort.
      
      
7. Size and Space for Approach and Use
   Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user’s body size, posture, or mobility.
   1. Provide a clear line of sight to important elements for any seated or standing user.
   2. Make reach to all components comfortable for any seated or standing user.
   3. Accommodate variations in hand and grip size.
   4. Provide adequate space for the use of assistive devices or personal assistance.

“Please note that the Principles of Universal Design address only universally usable design, while the practice of design involves more than consideration for usability. Designers must also incorporate other considerations such as economic, engineering, cultural, gender, and environmental concerns in their design processes. These Principles offer designers guidance to better integrate features that meet the needs of as many users as possible.”

In 1998, Ron Mace delivered his final public speech at the first international conference on universal design. He discussed the differences between assistive technology, barrier-free and universal design:

“Barrier-free design is what we used to call the issue of access. It is predominantly a disability-focused movement. Removing architectural barriers through the building codes and regulations is barrier-free design. The [Americans with Disabilities Act] Standards are barrier-free design because they focus on disability and accommodating people with disabilities in the environment. In fact, the ADA is the now the issue of access in this country.

So, what is the difference between barrier-free and universal? ADA is the law, but the accessibility part, the barrier-free design part, is only a portion of that law. This part, however, is the most significant one for design because it mandates what we can do and facilitates the promotion of universal design. But, it is important to realize and remember that ADA is not universal design. I hear people mixing it up, referring to ADA and universal design as one in the same. This is not true.

Universal design broadly defines the user. It’s a consumer market driven issue. Its focus is not specifically on people with disabilities, but all people. It actually assumes the idea, that everybody has a disability and I feel strongly that that’s the case. We all become disabled as we age and lose ability, whether we want to admit it or not. It is negative in our society to say “I am disabled” or “I am old.” We tend to discount people who are less than what we popularly consider to be “normal.” To be “normal” is to be perfect, capable, competent, and independent. Unfortunately, designers in our society also mistakenly assume that everyone fits this definition of “normal.” This just is not the case.

Assistive technology to me is really personal use devices—those things focused on the individual—things that compensate or help one function with a disability. Many of you wear eyeglasses because you have limited sight. The assistive technology is your eyeglasses. We could legitimately say that everybody who wears eyeglasses has a disability.”

This is a good starting point, but I read in these principles a disconnect between designer and user. The user is not a part of the design process except as an object of measurement — a consumer rather than a participant. If universal design is intended to be usable by all people without the need for adaptation or specialized design, a more participatory and inclusive design process seems to be one useful way of achieving this. I’ve not yet found a handy list of such principles for the development of universal design.

Also as noted in the conclusion to the principles, these focus on physical interaction and do not address the physical life span of the design or its existence in the broader cultural world. Usability through degradation and reuse fall partially under “sustainable design.” The cultural context, though, surely shapes legibility, user assumptions, and what is considered normative just as much as the physical context.

As Mark Robbins, former NEA Design Director, said on the promotion of universal design principles:

“Central to universal design is a developing awareness of difference that questions normative standards. The sense of what is the norm needs to change.”

Simply put, underlying the principles of interaction listed above is another basic principle. From Leslie Weisman:

“Architects and planners have traditionally defined the ‘user,’ or the ‘public’ in the case of urban planning, in very narrow terms. Rather than recognizing the vast array of ages, cultures, and lifestyles that use buildings and public spaces and that actually exist in communities, architecture and planning theory has been based on a conception of the ‘user/citizen’ that is inherently masculine, and a ‘public’ that tends to be made up of middle-class white people living in nuclear families. So when architects and planners attend to the provision of housing, transportation, and community services, they have tended to design and plan for only a small segment of the population, thereby creating many problems for the ever-increasing numbers of people who do not fit into this assumed definition and life pattern.”

Universal design is vehicle for promoting social equality and justice, environmental sustainability, and human health and well-being. This is as not just design for equal use, but for unemcumberbed participation in everyday life, and in public life. This is design for democrcacy.
