  • A Task Definition Language for Virtual Agents  
  • by Spyros Vosinakis, Themis Panayiotopoulos — 2003 — In Journal of WSCG
  • …The use of Virtual Environments as a user interface can be important for certain types of applications, especially in the fields of education and entertainment. These synthetic worlds are even more attractive for the user when they exhibit dynamic characteristics and are populated by virtual agents.…

  • 2003a): Programmable Agent Perception in Intelligent Virtual Environments  
  • by Spyros Vosinakis, Themis Panayiotopoulos — In Lecture Notes in Computer Science 2792
  • …Abstract. In this paper, we propose a perception model for virtual agents based on a two-layered architecture. Each agent is equipped with a sensing mechanism that retrieves the objects in its field of view and stores them in its memory, and with a perception module that applies a set of rules on th…

  • SimHuman: A Platform for Real-Time Virtual Agents with Planning Capabilities  
  • by Spyros Vosinakis, Themis Panayiotopoulos — 2001 — In Proceedings of the 3rd International Workshop on Intelligent Virtual Agents (IVA 2001
  • …In this paper, we present SimHuman, a platform for the generation of real-time 3D environments with virtual agents. SimHuman is highly dynamic and configurable, as it is not based on fixed scenes and models, and has an embedded physically based modelling engine. Its agents can use features such …

  • A tool for constructing 3D Environments with Virtual Agents  
  • by Spyros Vosinakis, Themis Panayiotopoulos — 2005 — In Multimedia Tools and Applications
  • …Abstract. The use of Virtual Environments as a user interface is essential for certain types of applications, both in education and entertainment. These worlds are even more attractive for the user when they are neither static nor pre-scripted, but have dynamic characteristics and are populated by a…

  • Temporal Disjunctive Logic Programming  
  • by Manolis Gergatsoulis, Panos Rondogiannis, Themis Panayiotopoulos — 1997
  • …In this paper we introduce the logic programming language Disjunctive Chronolog which combines the programming paradigms of temporal and disjunctive logic programming. Disjunctive Chronolog is capable of expressing dynamic behaviour as well as uncertainty, two notions that are very common in a v…

  • Virtual Agent Societies with the mVITAL Intelligent Agent System  
  • by George Anastassakis, Themis Panayiotopoulos, Tim, Tim Ritchings — 2001 — Lecture Notes in Computer Science
  • …Intelligent multi-agent systems are currently used for a variety of purposes, both in research and for real-world applications. One of their most interesting, yet not fully explored uses, is as frameworks to support computerbased simulations of virtual worlds inhabited by life-like entities, that…

  • Multi-agent Systems as Intelligent Virtual Environments  
  • by George Anastassakis, Tim Ritchings, Themis Panayiotopoulos — 2001 — In: Proceedings of Advances in Artificial Intelligence, Joint German/Austrian Conference on AI - KI 2001. Volume 2174 of Lecture Notes in Computer Science
  • …Intelligent agent systems have been the subject of intensive research over the past few years; they comprise one of the most promising computing approaches ever, able to address issues that require abstract modelling and higher level reasoning. Virtual environments, on the other hand, offer the i…

  • DIVA: Distributed Intelligent Virtual Agents  
  • by Spyros Vosinakis, George Anastassakis, Themis Panayiotopoulos, T. Panayiotopoulos — 1999 — University of Salford
  • …In this paper we present DIVA, an architecture for Intelligent Virtual Environments. In DIVA, systems consist of three different modules. There is a World Server that represents the environment in an abstract way, an arb itrary number of Intelligent Agent Clients acting as the world's inhabitant…

  • An Intelligent Agent Framework In VRML Worlds  
  • by Themis Panayiotopoulos, T. Panayiotopoulos, George Katsirelos, Spyros Vosinakis, Sophie Kousidou — 1998 — Intelligent Systems & Control Conference, EURISCON’98
  • …actions, e.g. move to next room, are received by it and consequently send to the EAC. Finally, the abstract action arrives at the Virtual Reality Management Unit that specifies in detail the received actions. It provides specific values concerning the orientation and position of the avatar, e.g. it …
