Shared Displays: An Overview of Perceptual and Cognitive Issues
Abstract
Large screen shared displays are a standard fixture in most command and control (C2) centers, but are often under-utilized. Many of the problems stem from the fact that shared displays are repeater displays from individual workstations. Scaling from workstation displays to large screen displays does not guarantee text will be large enough to be visible to all users. The colors and color range visible on the shared displays may not automatically match the colors displayed on individual workstations. Text and symbology overlays on maps are often not discernible when translated from individual workstations to shared displays. And when shared displays are repeaters, the operator's navigation and control icons, menus and pallets are visible on the shared displays and obstruct the view of displayed information. Shared displays often present what is called a common operating picture, or COP. The COP should be the basis of a common operational understanding, but they are often too cluttered, yet lack useful information. In today's complex environment of asymmetric warfare, effects-based operations and coalition forces, decision quality information is needed to support collaboration and synchronization of operations. This means delivering the right information at the right time in a clearly visible and easily understandable format that supports cognitive processes associated with situation awareness, decision making, and collaboration. The present paper will discuss perceptual and cognitive issues associated with shared displays and COPs in command centers.
