Functional Accessibility Through Universal Design



7 Tenets of Universal Design

1. Equitable use: The design is useful and marketable to people with diverse abilities.

  • Provide the same means of use for all users.
  • Provisions for privacy, security, and safety should be equally available to all users.
  • Make the design appealing to all users.

 

2. Flexibility in use: The design accommodates a wide range of individual preferences and abilities.

  • Provide choice in methods of use.
  • Facilitate the user’s accuracy and precision.
  • Provide adaptability to the user’s pace.

 

3. Simple and intuitive: Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.

  • Eliminate unnecessary complexity.
  • Be consistent with user expectations.
  • Accommodate a wide range of literacy and language skills.

 

4. Perceptible Information: The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.

  • Use different modes (pictorial, oral, tactile) for redundant presentation of essential information.
  • Provide adequate contrast be­tween essential information and its surroundings.
  • Differentiate elements in ways that can be described.


5. Tolerance for error: The design minimizes hazards and the adverse consequences of accidental or unintended actions.

  • Arrange elements to minimize hazards and errors: most-used elements, most accessible; hazardous elements eliminated or shielded.
  • Provide warnings of hazards/errors.
  • Provide fail-safe features.

6. Low physical effort: The design can be used efficiently and comfortably and with a minimum of fatigue.

  • Allow user to maintain a neutral body position.
  • Use reasonable operating forces.
  • 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.

  • Provide a clear line of sight to important elements for any seated or standing user.
  • Make reach to all components comfortable for any seated or standing user.
  • Provide adequate space for the use of assistive devices or personal assistance.
