Abstract

A mechanism for modifying a chat distance associated with an environmental chat based on the avatar population density of an area of a virtual universe associated with the environmental chat. An initial environmental chat distance may be determined based on the avatar population density, i.e., the number of avatars, in the area of the virtual universe associated with the environmental chat. The environmental chat distance may be modified in response to a change in the number of avatars in the area of the virtual universe associated with the environmental chat. The environmental chat distance may be modified such that the environmental chat distance is inversely proportional to the detected number of avatars in the virtual universe area associated with the environmental chat.
