In the history of design, it may be remarked that the world is in a new paradigm shift at the level of breaks in the transition to agriculture, industry, and information societies. As in many fields of design, interior design is also evolving in terms of design thinking as well as being subject to change in all processes under the influence of intensive technological development. While information technologies are implicated as aides in the design processes in the early stages of this evolution, they are now used for creating unique design and production approaches. This chapter discusses and re-interrogates the contributions and effects of these developments on the structure of interior design methodologies.
