Gesture modeling: improving spatial recognition in architectural design process

In this paper, we discuss the role of spatial cognition during the architectural design activity, and how it affects design creativity. Recognizing that current CAD applications' Windows-Icon-Menu-Pointer (WIMP) user interfaces do not fully support creative exploration in modeling geometries for design, we design a prototype system that incorporates a regular pc and a depth camera for gestural input. We present the implementation and use scenario of the system, and discuss why gestural input may advance creativity in the design process.
