Transparent displays naturally support workspace awareness during face-to-face interactions. Viewers see another person's actions through the display: gestures, gaze, body movements, and what one is manipulating on the display. Yet we can design even better collaborative transparent displays. First, collaborators on either side should be able to directly interact with workspace objects. Second, and more controversially, both sides should be capable of presenting different content. This affords:

Third, the display should visually enhance the gestural actions of the person on the other side to better support workspace awareness. We show how our FacingBoard-2 design supports these collaborative requirements, and confirm via a controlled study that visually enhancing gestures is effective under a range of deteriorating transparency conditions.
