The chapter seeks to define virtual reality. It looks into seven elements that constitute the term. Simulation refers to the modern computer graphics and sound effects that can create such a high degree of realism. Interaction refers to electronic representations that people perceive as virtual reality by their interacts with with them. Artificiality refers to a world that is largely of human construct. Immersion refers to the computer-generated sensations to which a man can immerse his sensory perceptions to simulate reality. Telepresence refers to the capacity of computer technology to replace human presence by robotic presence. Full-body immersion refers to the latest technology that allows human body to interact with graphics on a computer screen. Networked communications refers to communication that can go beyond verbal or body language to take on magical, alchemical properties. A virtual-world maker might conjure up hitherto unheard-of mixtures of sight, sound, and motion.
