Universal design is based on several concepts:
- Equitable use: All people use the design features in the same way.
- Flexibility in use: The feature can be adjusted depending on the user; for example, both right- and left-handed people could use it.
- Simple and intuitive: Any user could understand the feature, regardless of knowledge level or language.
- Perceptive information: It’s easy to determine information associated with the feature.
- Tolerance for error: The design minimizes danger and potential consequences of misuse.
- Low physical effort: You won’t break a sweat.
- Size and space for approach and use: Whether seated or standing, you have the room to get around and the ability to reach for things.
