PortholesTNG — A Group Awareness ToolA group awareness tool provides group and individual information to members of a physically distributed work group. This information allows the users to formulate a general and peripheral awareness of their co-workers. Such tools are intended to re-create some of the information that are available to co-located group members but are unavailable to individuals who are not co-located. The information may include general information about the physical and social environment, knowledge of and activities of individuals and groups, and information relevant to opportunities for collaboration and coordination. The initial and more prevalent forms of these awareness tools have used video and video images as the information kernel. In recent years, a number of researchers have proposed the use of representations, other than video or video images, that are more abstract, compact, and iconic. There are two different flavors of video-based group awareness tools: portholes and glances. Portholes provide an integrative view of one's community through a matrix of still video images (see Xerox Polyscope [1], Xerox Portholes [3], and NYNEX Portholes [5]). These images are snapped periodically (e.g., every 5 minutes) and the matrix is updated automatically. As a result, users can get a peripheral or background sense of their co-workers and activities. Glances provide electronic analogues of users strolling down a hallway and intentionally glancing into people's offices (see Bellcore Cruiser [2] and Sun Microsystems' Montage[6]). Portholes provide users with awareness in the periphery of their attention (i.e., passive awareness), while glances are explicit, intentional, remote queries into a co-worker's work space (i.e., active awareness).
