A method and communication system are disclosed for conducting a conference among sets of conference participants connected by a communication system. This system has at least one conference server, at least one image reproduction unit at each conference environment and at least one microphone at each conference environment. The method involves calculating respective virtual images of a majority of the conference environments, each virtual image containing at least one image corresponding to at least one conference participant who is present at that conference environment, calculating an aggregate representation of the virtual images of all conference environments and displaying the aggregate representation on at least one image reproduction unit. The method also calculates an individual representation for an individual conference participant and provides the individual participant with the individual representation while simultaneously providing to that individual the aggregate representation.
