Spatial Cognition and Architectural Design in 4 D Immersive Virtual Reality : Testing Cognition with a Novel Audiovisual CAVE-CAD Tool

The development of new 3D visualization technologies and novel algorithms for calculating and dynamically displaying complex structures in large-scale immersive CAVE facilities provides a transformational opportunity to designers and architects, as well as cognitive scientists interested in understanding complex tasks involved in spatial cognition. Approaches commonly in use by architectural designers to render 3D structures include a variety of computer aided design (CAD) tools that simulate 3D objects on a flat 2D computer screen. Although such screen-based visualizations are referred to as 3D models, they must be interpreted by the human brain as a 3D object, and require the viewer to imagine the egocentric experience accurately. Whereas highly trained design professionals may have greater cognitive facility with this mental transformation, clients and users are often unable to create accurate mental representations from 2D plans and elevations or indeed from "3D walkthroughs" viewed on 2D desktop screens. For the cognitive scientist, the availability of more realistic representations that involve multiple coordinated sensory modalities offers the possibility of studying spatial cognition using more natural experimental conditions.
