Indicate that form follows function. The physical form of an elegant product follows its function. To read Wired, you have to be a masochist because of its page design. Form, in these cases, conflicts with function. Use materials truthfully.
Elegant products use materials in logical, natural ways.
Materials are not used to make a statement or to jar people s sensibilities. A computer made out of teak, for example, is a dishonest use of wood. Permit direct and immediate manipulation. Elegant products enable users to control and not be controlled. Actions are concrete, not abstract, and the user not the product, initiates control.
