Universal Design PrinciplesEquitable Use The design is useful and marketable to any group of

users

● Provide all users with the same means of use: identical if possible; equivalent when not.

● Avoid segregating or stigmatizing any users.● Security, safety and protection requirements should

be applicable to all users equally● Make the design appealing to all users.

Flexibility of Use

Simple and Intuitive

The design accommodates a wide range of individual preferences and abilities

● Provide choice in methods of use.● Accommodate right-or-left-handed access and use.● Facilitate the user’s accuracy and precision.● Provide adaptability to the user’s pace.

Use of design is easy to understand● Eliminate unnecessary complexity● Be consistent with user expectations and intuition.● Accommodate a wide range of literacy and

language skills.● Arrange information through its level of importance

Universal Design Principles

Perceptible Information

Tolerance for Error The design minimizes hazards and the adverse consequences of accidental or unintentional actions

● Arrange elements to mitigate hazards and errors: most of the elements used, most accessible; remove, separate, or cover hazardous elements.

● Provide warning of hazards and errors.● Provide fail safe features.● Discourage unconscious action in tasks that require

vigilance.

The design communicated necessary information effectively to the user

● Use various ways (pictorial, verbal, tactile) to present repetitive vital information.

● Provide sufficient contrast between vital information and its surroundings.

● Maximize “legibility” of vital information.● Differentiate elements in ways that can be described

(i.e., make it easy to give instructions or directions).● Provide compatibility with a variety of techniques or

devices used by people with sensory limitations.

Universal Design Principles

Low Physical Effort

Size and Space for Approach and Use Appropriate Size and Space is provided for approach and use

● Provide a clear line of sight to important elements for any seated or standing user.

● Make it easy for any sitting or standing user to reach all components.

● Accommodate variations in hand and grip size.● Provide sufficient space for the use of support or

personal assistance devices.

The design can be used efficiently and comfortably

● Allow user to maintain a neutral body position.● Use reasonable operating forces.● Minimize repetitive actions.● Minimize sustained physical effort.
