Virtual World = Architectural Design + Computational Elements Mary Lou Maher and Ning Gu ANZAScA 2002 KCDCC Virtual Worlds = Architectural Design + Computational Elements 0 Mary Lou Maher and Ning Gu mary@arch.usyd.edu.au nigu6276@arch.usyd.edu.au Key Centre of Design Computing and Cognition University of Sydney ç Virtual Worlds - Multi-user networked 3D Virtual Environment. ç Architectural Design - Result of the use of architectural metaphor. ç Computational Elements - Provide programmable functions.

2. Virtual World = Architectural Design + Computational Elements Mary Lou Maher and Ning Gu ANZAScA 2002 KCDCC Introduction: Virtual Worlds 1 ç Metaphor of Physical Architecture - Analogy from Physical Architecture. - Adaptation to Virtual Context. ç Constraints in Design - Physical Architecture: due to the context of geographical context. - Virtual Architecture: free from physical constraints, but extremely abstract forms tend to be disorienting and distracting. ç Organisation of Virtual Worlds - Provide a Cognitive map by referring to physical architecture. - Extend the capabilities by having behaviours only exist in virtual domain.

5. Virtual World = Architectural Design + Computational Elements Mary Lou Maher and Ning Gu ANZAScA 2002 KCDCC Virtual World Design Space 2 ç Active Worlds - A multi-user 3D world that works on the internet as a client-server application. ç F-B-S (Gero 1990) in Virtual Context - Function: intended purposes. - Behaviours: programmed computing elements. - Structure: an aggregation of 3D models. ç Active Worlds as A Design Platform - The designed space for the structure of the world is a library of 3D models categorised according to a set of architectural categories of objects - The design space for the behaviour of the world is a set of triggers and actions.

15. Virtual World = Architectural Design + Computational Elements Mary Lou Maher and Ning Gu ANZAScA 2002 KCDCC Conclusion 5 ç Beyond Being There - A virtual world is not constrained by the physical. - Behaviours can be ascribes to objects in the world that are relevant to being in a virtual place. ç A New Set of Design Principles - Requirements that are associated with the experience of virtual presence. - The way a person interacts with a world through the input devices of a keyboard and mouse. ç Metaphorical Design - A clear reference to the physical world providing a comfort zone for people interacting with each other and the virtual world.
