Augmented urban planning workbench: overlaying drawings, physical models and digital simulation

There is a problem in the spatial and temporal separation between the varying forms of representation used in urban design. Sketches, physical models, and more recently computational simulation, while each serving a useful purpose, tend to be incompatible forms of representation. The contemporary designer is required assimilate these divergent media into a single mental construct and in so doing is distracted from the central process of design.
