“…Marks et al [14] have analyzed the possibility of using game engines as the environment to implement medical applications and, even though current game engine technology cannot offer the level of realism observed in the previously described applications, it offers interesting and cost-effective alternatives to produce fast and fairly accurate implementations. For instance, Cavazza and Simo [15] developed an application that simulates a virtual patient using the Unreal Tournament game engine. 3 The wide range of features offered by current game engines allow medical application developers to easily create accurate scenarios based on real situations.…”

Abstract-Recently, virtual world technology has been successfully used to create interesting and useful applications in the context of scientific research, ranging from visualization of static 3D representations of molecular entities to full execution of astrophysical simulations. Unfortunately, the majority of these applications are somewhat limited by the current functionality of the virtual world client software, constraining them to provide only the most basic features of user interfaces. Thus, the implementation of applications such as training programs becomes quite challenging due to the high level of interaction a user must have with the training environment itself. In order to analyze the level of usability for virtual world based applications, we will introduce OpenBioSafetyLab, our implementation of a virtual world based training application in bio-risk management, which is one of the most important areas for training systems nowadays. We also present the results of our exploratory test study with twenty-four subjects, which indicates a high degree of usability of our system, not only for the testing aspect of the training, but also for the learning aspect.

“…It supports stereoscopic visualisation at 60 fps and real-time interaction. The QR Engine utilises the technique for qualitative simulation of physiological systems [4], derived from Qualitative Process Theory (QPT) [7] which we refer to as Qualitative Physiology. Qualitative Physiology represents the physiological processes governed by physiological laws using the process-based formalism of QPT, and supports the realtime simulation of physiological sub-systems.…”

“…This can be used to produce a variety of visualisations, such as particle systems for fluid motion or colour changes for concentration. The software architecture for the communication of these QP Events and QP Effects utilises the UDP protocol for transmission between the qualitative simulation engine and the visualisation engine, [4,5,6]. Figure 1 shows an overview of the system architecture.…”

Abstract.In this paper, we describe an approach to artificial life, which uses Qualitative Reasoning for the simulation of life within a 3D virtual environment. This system uses qualitative formalisms to describe both the physiology of a virtual creature and its environment. This approach has two main advantages: the possibility of representing integrated physiological functions at various levels of abstraction and the use of a common formalism for the simulation of internal (physiological) and external (environmental) processes. We illustrate this framework by revisiting early work in Artificial Life and providing these virtual life forms with a corresponding physiology, to obtain a complete living organism in virtual worlds.

“…The fact that a virtual environment could include a qualitative model of a device, while allowing interaction with its constituents can be used for various training tasks, such as maintenance [11]. We have previously developed a similar approach in a medical application, which used qualitative physiological models to simulate the condition of a virtual patient [2]. However, this kind of application probably needs to be extended to include explanatory capabilities.…”

In this paper, we describe a new approach to the creation of virtual environments, which uses qualitative physics to implement object behaviour. We adopted Qualitative Process Theory as a qualitative reasoning formalism, due to its representational properties (e.g., its orientation towards process ontologies and its explicit formulation of process' pre-conditions). The system we describe is developed using a game engine and takes advantage of its event-based system to integrate qualitative process simulation in an interactive fashion. We use a virtual kitchen as a test environment. In this virtual world, we have implemented various behavioural aspects: physical object behaviour, complex device behaviour (appliances) and "alternative" (i.e. non-realistic) behaviours, which can all be simulated in user real-time. After a presentation of the system architecture and its implementation, we discuss example results from the prototype. This approach has potential applications in simulation and training, as well as in entertainment and digital arts. This work also constitutes a test case for the integration of an Artificial Intelligence technique into 3D user interfaces.
