In this paper, an innovative multiparty videoconferencing system supporting eye contact and synchronous pointing based on the combination between human image and shared workspace is presented. We propose an idea to establish multiple eye contacts by representing each participant’s eyes with a small video camera. Therefore, participants are able to be aware of who is visually attending to them. All participants’ images are displayed as the image layer which is naturally merged with the shared workspace. With this method, the proposed system has the advantage of serving synchronous pointing of more than one site at a given time. The basic idea is to make camera’s view overlapped with pointing area by using the technique of camera’s angle and position. Therefore, multiple target points can be recognized simultaneously.
