The intent of universal design is to simplify life for everyone by making products, communications, and the built environment more usable by as many people as possible at little or no extra cost. Universal design benefits people of all ages and abilities.
Universal design is the design of products and environments to be usable by all people, to the
greatest extentpossible, without the need for adaptation or specialized design.
