Virtual sensors for dynamic virtual environments

Abstract

This paper proposes a sensor-based mechanism that allows virtual creatures to perceive the environment that surrounds them. We are keen on modeling the behavior of real-life creatures via VR-techniques. Every living creature is endowed by a number of senses, by means of which, the creature is aware of the world around. We picture the environment as a multi-agent system, where every agent has, primarily, a knowledge base, a sensors and effectors to allow interaction. The effectors may launch actions (graphical changes), noises, messages or aromas. The sensors model, particularly, the sight, hearing and smell senses of a living creature. Every sensor has specific perception capabilities and gathers partial or full information about the objects around. Through the sensors, a virtual creature is aware of the environment and capable to increase the knowledge base. The local state of a creature can be amplified by allowing cooperation between agents
