Large high resolution displays for co-located collaborative sensemaking: Display usage and territoriality

• We examined collaborative sensemaking on a large, high-resolution display.
• Integrated workspace collaborative styles yield better sensemaking.
• We make design suggestions for future collaborative tools on large displays.

From an exploratory user study using a fictional textual intelligence analysis task on a large, high-resolution vertical display, we investigated how pairs of users interact with the display to construct spatial schemas and externalize information, as well as how they establish shared and private territories. We investigated users' space management strategies depending on the design philosophy of the user interface (visualization- or document-centric). We classified the types of territorial behavior exhibited in terms of how the users interacted with information on the display (integrated or independent workspaces). Next, we examined how territorial behavior impacted the common ground between the pairs of users. Finally, we offer design suggestions for building future co-located collaborative visual analytics tools for use on large, high-resolution vertical displays.
