Generative design theories are needed to b ridge the gaps between pure scientific knowledge, individual ("point") designs and systematic generation of viable design alternatives. This paper suggests a framework for locomotional design that uses knowledge of navigation and spatial cognition to inform design. Examples of the implications of two such pieces of knowledge are sketched out, suggesting how this framework might lead to a generative design theory.
