the Space Between the Physical and the Virtual


Cognitive Agents in 3D Virtual Worlds

"Abstract: We present an agent-based model of virtual worlds in which the objects in the world have agency, that is, the objects can sense their environment, reason about their goals, and make changes to the environment. The agent-based model has the following reasoning processes: interpretation, hypothesizing, and action activation. This agent model is described and illustrated using a wall agent in a multi-user virtual world. We extend the illustration through a demonstration of a multi-agent world in which many of the objects in the world interactively reason about the use of the world and respond specifically to the people in the world." From Cognitive Agents in 3D Virtual Worlds by ML Maher, JS Gero, G Smith, N Gu, University of Sydney, Australia; International of Design Computing, Vol 6, 2003.

"Abstract: The cyberPRINT is a fully immersive, interactive virtual environment that is being generated in real time based on physiological data readings of a human body. In other words, the cyberPRINT is based on creating interfaces between physical and digital spaces and between biology and information technologies. The cyberPRINT is also an event, wherein a performer is connected to the cyberPRINT generator to create a self-sustaining feedback mechanism. Although the use of the body to electronically drive music and media events is not new, most of these works have paid little or no attention to the potential of interactive 3D virtual environments. Nor have they been so technologically advanced, interdisciplinary intensive (involving Architecture, Choreography, Modern Dance, Music, Bioengineering, Medicine and Computer Science), or architecturally focused as the cyberPRINT.

This project covers a wide and fertile territory that goes from the very technical and design oriented to the very theoretical and interdisciplinary. This paper is intended to (1) expand what has been already published about this project (Bermudez et al 2000a) and (2) establish potential areas for discussion before and after the performance."

1. Introduction: Why a Live Performance?

This paper provides background for the live performance of the cyberPRINT, a real time, physiologic data-driven virtual architecture developed by an interdisciplinary team led by two architects during the past 5 years. The reason for this live performance and demonstration is simple. It is only through performance that we can show the true nature of the cyberPRINT. Such demonstration will also provide empirical proof of the theoretical claims and technological details already published elsewhere (Bermudez et al 2000a). In addition, this version of the cyberPRINT will add some novelties occurred since then (such as a new virtual world, data-driven music in real time, a navigational data-globe). Images of a live performance are shown in Figure 1. [via]
