Oracles, draughtsmen, and agents: the nature of knowledge and creativity in design and the role of IT

We have had computer-aided design in architecture now for over four decades. During this time, the computer has been used in several quite different roles, some of which will be discussed here. However, so far, the contribution the computer has made to supporting creative design remains patchy and uncoordinated [B.R. Lawson, CAD and creativity: does the computer really help? Leonardo 35 (3) (2002) 327-331]. Why is this and what, if anything, can we do about it? One clue to this is that some four decades ago we also knew very little about the design process compared with our contemporary understanding [B.R. Lawson, How Designers Think, Oxford, Architectural Press, 1997.[2]]. Cerulli, C., C. Peng, et al. (2001).
