Life in these worlds springs from the presence of users, the interaction among them, and among software based entities. A physical identity which is the geometry that represents the user and its visual status 2. Combination of both where the users behavior is semi automated. The virtual identity of the individual, the user, or the inhabitant of the virtual community is a vital aspect to the success of the virtual world. Technology plays a large part in portraying the identity of the user.
Avatars are virtual humans controlled by a live participant.
The avatar is at its beginning phases of development. Though it is still very early, the dichotomy of the avatar is increasing rapidly. We are seeing more realistic avatars with an increase in individualistic behavioral and visual characteristics. Characteristics such as waving, running, dancing, facial expressions, having fashion accessories, all kinds of clothing, and artifacts such as cars, homes, and furniture. One major concern is to give the plethora of on-line users their own unique identities.
