Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses. Example rules are gravity, topography, locomotion, real-time actions, and communication. Such modeled worlds and their rules may draw from reality or fantasy worlds. The user accesses a computer-simulated world which presents perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of presence. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Large-scale, interactive computer-simulated environmentĪ virtual world (also called a virtual space) is a computer-simulated environment which may be populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others.
