and their working style), and the nature of the search task supported (such as the specific application
domain, types of inputs provided to the search system, and stages of the search process supported).
Físchlár-DT ( Smeaton et al. , 2006 ), for example, enables group members to search video col-
lections using a touch-sensitive, top-projected tabletop display. As shown in Figure 4.11, users type
keywords on the tabletop using virtual keyboards, and they can manipulate matching keyframes
using direct-touch interactions. The Personal Digital Historian ( Shen et al. , 2002 ), seen in Fig-
ure 4.12, is designed to support collaborative photo browsing and storytelling on a single touch-
screen. It enables groups to query a tagged photo collection by filtering along the dimensions
“who,” “what,” “where,” and “when.” TeamSearch ( Morris et al. , 2006 ) (Figure 4.13) is another
tabletop photo-searching system. TeamSearch enables group members to manipulate virtual tokens
in order to create a visual boolean representation of a query. Cambiera ( Isenberg and Fisher , 2009 )
(Figure 4.14) enables pairs of users to search over a document collection on a Microsoft Surface
( http://www.microsoft.com/surface ) , providing compact visualizations of search results in
order to save space on the shared display and indicate overlap among pairs' result sets. FourBySix
Search ( Hartmann et al. , 2009 ; Morris et al. , 2010a ) (Figure 4.15) enables the use of physical key-
boards placed atop a shared tabletop system; the relative distances of the keyboards impacts whether
typed query terms are interpreted separately or jointly, and their relative orientations impact whether
