For many of their tasks, Navy CIC operators sequentially select or otherwise browse tracks or contacts of interest. Both the symbology used and the design of the text readouts associated with selected tracks can impact performance. A set of four tasks was used to quantitatively compare operator performance with three different symbol sets - colorized Naval Tactical Data System (NTDS) symbols and modified MIL-STD-2525B symbols in a top-down plan view display, and realistic 3D icons in a perspective view display. For the 2D displays, two locations for text readout were assessed - adjacent to the track in question and in a fixed location. The 3D displays were found to provide no benefit for altitude estimation tasks, and comparison of results across tasks indicates that realistic aircraft symbols in a 3D display are harder to search than are 2D symbols. Including within the symbols more information of relevance to the operator improved response times by 40% to 60% in two different tasks. No consistent differences in performance were found for text readout location.
