Abstract: A method is provided for implementing and controlling virtual environments, for example “virtual worlds” by which users can for example meet one another virtually and communicate through their respective terminals. For example, the method relates to the display, rendering and/or deletion of the representations of users acting in these virtual environments, at the different terminals in which these representations can be viewed. The method includes the following steps for a given user: determination of a destination zone in the virtual environment in which the representation of the user is to be rendered; determination of an appearance zone in the virtual environment; displaying of the representation in the appearance zone; and automatic movement of the representation from the appearance zone to the destination zone.

Abstract: A method is provided for displaying a representation of a user in a virtual environment in which a plurality of user representations evolves. The method includes the following steps for a given user: determination of a destination zone in the virtual environment in which the representation of the user is to be rendered; determination of an appearance zone in the virtual environment; displaying of the representation in the appearance zone; and automatic movement of the representation from the appearance zone to the destination zone.

Abstract: A method is provided for monitoring a representation of a user in a virtual environment. The method includes: a step of continuous supervision of a state of transfer of data between a terminal of said user and an entity for management of said virtual environment; a step of adaptation of a behaviour of said representation following a modification of said data transfer state.
