Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.
Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.
Firstly, this thesis looks into literature from the fields of architectural and urban design theory, philosophy, environmental cognition, perceptual psychology and geography for the purpose of identifying a taxonomy of spatial elements and their structure in the real world, on the basis of the way that humans think about and remember real environments. Consequently, the taxonomy, proposed for space in the real world is adapted to the intrinsic characteristics of space in virtual environments, on the basis of human factors aspects of virtual reality technology. As a result, the thesis proposes a hypothetical framework consisting of a taxonomy of spatial and space-establishing elements that a virtual environment may comprise and of the possible structure of these elements.
Following this framework, several pilot virtual environments are designed, for the purpose of identifying key design issues for evaluation. As it was impossible to evaluate the whole framework, six specific design issues, which have important implications for the design of space in virtual environments, are investigated by experimental methods of research. Apart from providing answers to these specific design issues, the experimental phase leads to a better understanding of the nature of space in virtual environments and to several hypotheses for future empirical research.
