The document outlines the seven principles of universal design which aim to make products and environments usable by people of all abilities. The principles are: 1) equitable use, 2) flexibility in use, 3) simple and intuitive use, 4) perceptible information, 5) tolerance for error, 6) low physical effort, and 7) size and space for approach and use. Each principle is defined and an example is provided to illustrate how that principle can be applied. The overall goal of universal design is to design products and environments to be usable by all people without the need for adaptation.
