Maximizing Usability: The Principles of Universal Design

The Center for Universal Design at North Carolina State University has developed a set of seven Principles of Universal Design that may be used to guide the design process, to evaluate existing or new designs, and to teach students and practitioners. This article presents preceding design guidelines and evaluation criteria, describes the process of developing the Principles, lists The Principles of Universal Design and provides examples of designs that satisfy each, and suggests future developments that would facilitate applying the Principles to assess the usability of all types of products and environments.
