Recently, computer technologies have multiplied, and there
are large interactive displays that overcome some of the physical constraints of the relatively small display of a traditional desktop or laptop PC. This physical layout has also been
examined in the context of collaborative search, covering interactive whiteboards, table-top PCs and similar devices [5,
9, 13]. These technologies can promote simultaneous collaboration, and permit everyone to see a shared display that
co-ordinates the group's view of the media being worked
with - i.e. the referencing problem is by-passed through the
use of a single view. However, this does not give each person
an individual view.
