Let’s unpack the definition of universal design:


Part 1: “Design that is usable by all people…”

The biggest challenge of designing for “all people” is ensuring it’s functional for people with diverse abilities. Do it well, and the results will be usable and marketable to everyone.

Universal design is often misunderstood as only being for people with disabilities, but disability is part of the human condition. It’s not a diagnosis. Our bodies don’t always work as they should.

Universal design aims to make products and environments accessible and usable by everyone, regardless of age, ability, or status in life. The focus should be on creating intuitive, flexible, simple designs, minimizing physical effort, and accommodating all users through perceptible information presentation. UD emphasizes error tolerance and adequate space for approach and use, ensuring safety and comfort for all.

Illustration of a diverse group of a dozen or so people. An elderly gentleman is sitting in a wheelchair, and a young adult woman is leaning on a cane.

Part 2: “To the greatest extent possible…”

Something universally designed will work for as many people as possible, including those with any impairment of the body or mind. UD will be functional for anyone, regardless of if he or she has…

  1. Difficulty interpreting or processing information.
  2. A susceptibility to fainting, dizziness, or seizures.
  3. A speech impediment.
  4. Difficulty processing sensory input.
  5. Blindness (loss of sight).
  6. Low vision (limited sight).
  7. Deafness (loss of hearing).
  8. A hearing impairment.
  9. A mental health impairment.
  10. A need for caregiver assistance.
  11. Difficulty moving the neck or head.
  1. Limited stamina.
  2. Difficulty sitting.
  3. Limited coordination.
  4. Limited sensation.
  5. Limited balance.
  6. Loss of upper extremity motor control.
  7. Loss of lower extremity motor control.
  8. Difficulty reaching, lifting, or carrying items.
  9. Difficulty bending, kneeling, etc.
  10. A reliance on walking aids or mobility devices.
  11. Difficulty manipulating items.
  12. Chemical sensitivities.
  13. An extreme height or weight.

Part 3: “Without the need for adaptation or specialized design.”

Adaptation is a process in which an individual changes how he or she interacts with something. This often includes an assistive product or a different technique.

Specialized design is specific to a demographic or need. If elements in a design serve no purpose for some people, the design may be accessible [to some] but not universal [for all].

Universal design provides usability to everyone.

Important:

Some people have significant functional needs that require specialized design. If universal design is the foundation, adding specialized features (i.e., adaptations) as needed is much easier and more cost-effective than modifying an inaccessible design.
