Seven principles of universal design:
- Equitable use - the design is able to be used by people of all abilities.
- Flexibility in use - the design accommodates a variety of individual
- Simple and intuitive use - using the design is easy to understand
regardless of an individual's experience, knowledge, language skills, or
current concentration level.
- Perceptible information - the design effectively communicates necessary
information to the user.
- Tolerance for error - the design minimizes hazards and adverse
consequences of accidental or intended actions.
- Low physical effort - the design can be used comfortably and
efficiently, with minimal effort.
- Size and space for approach and use - sufficient size and space is
provided for reaching, approaching, and manipulating objects regardless of
users' body size, posture, or mobility.
