The Principles of Universal Design

I recently came across the Center for Universal Design at NC State University and I think this is going to be a great resource. Among its publications is a list of the Principles of Universal Design which provides seven principles and further guidelines for designing, well, anything. In short, these are

1. Equitable Use: The design is useful and marketable to people with diverse abilities.
2. Flexibility in Use: The design accommodates a wide range of individual preferences and abilities.
3. Simple and Intuitive Use: Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
4. Perceptible Information: The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
5. Tolerance for Error: The design minimizes hazards and the adverse consequences of accidental or unintended actions.
6. Low Physical Effort: The design can be used efficiently and comfortably and with a minimum of fatigue.
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.

It's easier to see how some of these apply to software and website development versus others, but I think there is something to be gained by keeping all these principles in mind when creating user interfaces. As an added bonus, the Center has also provided convenient printout poster versions.
