CEDE: Collaborative Egocentric Design Environment for CAVE

The geographical separation of the users and insufficient input from pairs may cause undesired costs in interior/exterior design process. If immersive communication and interaction exist between the pairs, those undesired costs will be minimal. Lack of communication and understanding causes much of the design works to be lost as it is improperly passed on and/or incompletely understood. The combined immersive collaboration can solve these existing problems so that the undesired costs can be eliminated. We present a framework for 3D design of interior/exterior spaces using a CAVEbased immersive virtual environment in that better and intuitive communication among the designers and users would lead to better integration of overall design such that designer would cede some of his/her work to the user. We have developed several user interface and intuitive spatial egocentric/exocentric perception and perceptual constancy techniques to build a fully interactive environment for novice users to help design process of interior or exterior spaces. Efficiencies of these spatial intelligence techniques’ are investigated with several experimental cases.
