“the design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design” 

∼ Definition from Ron Mace, founder of the Center for Universal Design at NC State University

See page that looks at two different frameworks for understanding the principles of universal design as well as a list of online references.

This page highlights three videos describing universal design. The first is Dr. David Rose from CAST, the second comes from Colorado State University, and the third from the University of Washington's Disability, Opportunity, Internetworking, and Technology (DO-IT).
