We are demonstrating several intelligent agents built according to the MGLAIR (Modal Grounded Layered Architecture with Integrated Reasoning) agent architecture. The top layer of MGLAIR is implemented in SNePS and its acting subsystem, SNeRE (the SNePS Rational Engine). The major demonstration will be act 3 of The Trial The Trail, an interactive drama running on an immersive Virtual Reality system, in which a human participant interacts with several MGLAIR actor-agents. We will also demonstrate several olher MGLAIR agents that operate in non-VR graphical environments. All these agents illustrate our approach to building agents with integrated first-person, on-line reasoning and acting.

The Trail is an interactive drama running on an immersive VR system. Imagine Tarkovsky's Stalker, crossed with Alice Through the Looking Glass, crossed with Monty Python and the Holy Grail. Now imagine embarking on a guided journey through this warped yet familiar landscape. Your guides are two intelligent agents, Patofil and Filopat. We consider a virtual reality drama to be a scripted play in which the computational agents are actors who have copies of the script, and one human audience member has been drafted to be a participant, but doesn't have a copy of the script. The computational actors must improvise reactions to the human participant's actions, but keep the play moving along in as close agreement to the script as possible. The goal is to provide the human participant with a specific emotional experience.

The paper discusses a virtual mail system. V-mail is designed to be used in the CAVE virtual environment. The participants' mail messages and the ongoing modifications of the VE are maintained by a central server. V-mail's user interface is embodied in a virtual friend or pet that follows the participant as he/she interacts with the VE.

Abstract We provide an overview of the use of intelligent agents, implemented in the new MGLAIR architecture, in a virtual reality drama. For us, a virtual reality drama is a scripted play in which the computational agents are actors who have copies of the script, and one human audience member has been drafted to be a participant, but doesn’t have a copy of the script. The computational actors must improvise reactions to the human partpicipant’s actions, but keep the play moving,along in as close agreement to the script as possible. The goal is to provide the human,participant with a specific emotional experience. We explicate this philosophy; outline the previously described GLAIR architecture; explain the introduction of an organization into modalities that results in the new MGLAIR architecture; describe our current VR drama, The Trial, The Trail; and discuss the implementation of our actor-agents. Our discussion of the actor-agents focuses on their abilities to react to triggers (cues), their performance of contingent actions that are off the main-line arc of the script, their use of timers to pace the drama, and the organization of the cast of actor-agents into a multi-agent system. 1 Virtual Reality Drama
