Abstract
Large interactive displays are increasingly being placed in work and public settings. An assumption is that the shared surface they provide can facilitate collaboration among co-located groups. An exploratory study was carried out to investigate this claim, and, in particular, to examine the effects of the physical orientation of a display on group working. Two conditions were compared: vertical versus horizontal. A number of differences were found. In the horizontal condition group members switched more between roles, explored more ideas and had a greater awareness of what each other was doing. In the vertical condition groups found it more difficult to collaborate around the display. A follow-up study explored how participants, who had previous experience of using both displays, determined how to work together when provided with both kinds of display. The groups exhibited a more efficient and coordinated way of working but less collaboration in terms of the sharing and discussion of ideas.
