Universal design principle | Description | Example |
|
(1) Equitable use | Useful and marketable to people with diverse abilities | Doors that automatically open |
|
(2) Flexibility of use | Accommodates a wide range of individual preferences and abilities | Automated teller machines’ buttons far enough apart to be pressed accurately |
|
(3) Simple and intuitive use | Easy to understand, regardless of user’s experience, knowledge, language skills, or current concentration level | Providing furniture assembly instructions in a series of clear illustrations instead of text |
|
(4) Perceptible information | Communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities | Computer software that relays information visually through text and pictures, and audibly through speakers |
|
(5) Tolerance for error | Minimizes hazards and the adverse consequences of accidental or unintended actions | Hallways that return to common areas rather than stop in dead ends |
|
(6) Low physical effort | Can be used efficiently and comfortably with a minimum of fatigue | Bottle caps that are easy to grip and require only a small range of motion to open |
|
(7) Size/space for approach/use | Appropriate size and space is provided for approach, reach, manipulation, and use regardless of the user’s body size, posture, or mobility | Wall mounted components (i.e., toilet paper) that are visible, easy to reach, and easy for all hand sizes to use |
