Digitally augmented sketch-planning

Abstract

While many aspects of the planning profession have changed radically in light of recent technological advances, the practice of sketching plans has remained largely unaffected. There may be good reasons for eschewing computers in the design arena such as that their use may detract from the liberty of the design thinking process. This thesis suggests that this reluctance may be overcome by changing the practice from one of emulation with digital tools to one of "augmentation". In addressing a perceived need to bring computation to the design table a solution called the "digitally augmented sketch planning environment" (DASPE) has been developed. Making use of video projection, DASPE augments the design space with digital visualization and analysis tools and allows planners to sketch using either conventional media or a pen stylus on a digitizing table. Plans can be sketched in the conventional manner, then "hardened" into three dimensional computer models without the need to leave the design space.
