An audio/video communication system displays the status of participants in a video chat session. The system includes multiple video chat capable (VCC) information handling systems (IHSs) that display video images of the participants. In this manner, each user may see the user's own video image as well as the video images of other users in the video chat session. When a user speaks, that user's VCC IHS detects audio, thus designating a speaker participant. This user's VCC IHS includes a gaze direction detector that determines at which particular user video image the user gazes, thus determining a target participant. The VCC IHS sends speaker participant ID information and target participant ID information to other VCC IHSs in the video chat session. In response, the other VCC IHSs display an indicator that designates one user video image as the speaker participant and another user video image as the target participant.
