Tämä on vanhan kertausta (vuodelta 1997), mutta tämänkertainen toteutus on niin hyvin esimerkkikuvien kanssa taitettu, että ansaitsee tulla mainituksi: The Principles of Universal Design. ”The authors, a working group of architects, product designers, engineers and environmental design researchers, collaborated to establish the following Principles of Universal Design to guide a wide range of design disciplines including environments, products, and communications. These seven principles may be applied to evaluate existing designs, guide the design process and educate both designers and consumers about the characteristics of more usable products and environments.”
