In computing, an avatar is the graphical representation of the user or the user's alter ego or character. An icon or figure representing a particular person in a video game, Internet forum, etc. It may take either a three-dimensional form,^[1] as in games or virtual worlds, or a two-dimensional form as an icon in Internet forums and other online communities.^[2][3] Avatar images have also been referred to as "picons" (personal icons)^[4] in the past, though the usage of this term is uncommon now. It can also refer to a text construct found on early systems such as MUDs.^[5] The term "avatar" can also refer to the personality connected with the screen name, or handle, of an Internet user.^[6] Common avatars may be Internet memes.

Virtual world

From Wikipedia, the free encyclopedia

"Game-based world" redirects here. For fictional universes, see Fictional universe.

A virtual world is a computer-based simulated environment^[1] 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.^[2] These avatars can be textual, two or three-dimensional graphical representations, or live video avatars with auditory and touch sensations.^[3][4] In general, virtual worlds allow for multiple users but single player computer games such Skyrim can also be considered a type of virtual world.^[5]

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.^[6] Such modeled worlds and their rules may draw from reality or fantasy worlds. Example rules are gravity, topography, locomotion, real-time actions, and communication. Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses.

Massively multiplayer online games depict a wide range of worlds, including those based on science fiction, the real world, super heroes, sports, horror, and historical milieus. The most common form of such games are fantasy worlds, whereas those based on the real world are relatively rare.^{[original research?][7]} Most MMORPGs have real-time actions and communication. Players create a character who travels between buildings, towns, and worlds to carry out business or leisure activities. Communication is usually textual, but real-time voice communication is also possible. The form of communication used can substantially affect the experience of players in the game.^[8]
