All the devices discussed so far allow the users to obtain information about the sense of presence and workspace awareness aiming at reproducing the real world interaction found in physical meeting. Whereas they provide valuable awareness information, they are not able to inform the exact place where the participants’ focus of attention is during group work. This focus of attention is part of the concept of pc network configuration, which is defined as the specific place of the shared workspace where the users are looking at.
The connection between the focus of attention and the place where a person is looking at is presented. By conducting psychological experiments and studying its results, they provided evidence that the user’s point of regard, which can be calculated by the projected trajectory of the direction, is one indicator of his focus of attention. Based on this assumption, the direction can be used to indicate the exact place containing the user’s current focus of attention.
