New technical innovations in telepresence allow people to attend meetings or gather together anywhere they are and to share the same virtual space using 3D avatars. More sophisticated systems have been developed with 3D capturing and rendering, leading to a true 3D telepresence experience. If the 3D avatar is remotely guided by the real participant, it is possible to replace this real participant by his or her autonomous virtual counterpart, as an i-substitute. The i-substitute is supposed to give a partial illusion that the real person is present. This implies that the i-substitute should look the same as the real human, speak with the same intonation, and be somehow aware of the real situation, the real participants, and the task currently being performed. The i-substitute should react at the right time based on the perception he/she has from the real participants. It implies an evaluation of what each real participant is doing. Perception will be obtained by visual and audio input and recognition. The i-substitute reacts according to the input and its current knowledge; its reactions encompass animation (body and facial gestures) and speech synthesis. The i-substitute could be an autonomous virtual human as well as a social robot, depending on the type of meeting and environment.
