Tactical Situation Displays and Figurative Symbology

摘要

This thesis investigates the utility of figurative symbology for tactical situation displays. The purpose was to determine if more descriptive symbology--figurative symbology or use of more lifelike images to represent targets--would enhance evaluation of a tactical situation display, i.e., enable the user to more rapidly assimilate and evaluate tactical situation display. Basis for comparison was the the Navy Tactical Display System (NTDS). Specifically, experiments used in our research included comparisons of monochromatic NTDS, color NTDS, and color figurative symbologies. The analysis of the data obtained from the experiments suggests color symbology is significantly better than monochromatic symbology and figurative is better than NTDS symbology. Specifically, color figurative (green/red) was determined to be best, followed in order by, color figurative (blue/orange), color NTDS, then monochromatic NTDS.
