Abstract

We introduce a novel approach to the creation of Virtual Reality Art installations, which supports the design of alternative worlds, in which laws of Physics can be redefined to induce new user experiences. To implement this concept of "Alternative Reality", we have used Artificial Intelligence techniques to support the definition of the virtual environment behaviour, an approach inspired by Qualitative Reasoning systems. Besides the redefinition of physical laws, we have developed mechanisms for eliciting causal relations between events, as causality plays an important part in users' perception of virtual worlds. Our pilot installation is a CAVETM-like system incorporating a state-of-the-art computer game engine as visualisation software, which has-been ported to this immersive display. The event-based system underlying the game engine is used to bypass the native Physics engine and replace it with our Alternative Reality software. A first prototype has been fully implemented, the Alternative Reality modules totaling over 100,000 lines of C++ code. We present early results obtained with this approach, illustrated with examples taken from two artistic briefs, developed by digital artists associated to this research.
