| Popis: | Previous studies conducted to derive the global command and control (C2) information requirements revealed categories or “windows” of information needed for the Theater High Altitude Area Defense (THAAD) system. The experiment reported here was conducted to determine the optimal presentation of local features for one global area of the interface: equipment status monitoring. Participants from the Army Air Defense School performed THAAD tasks under two levels of information load, using four equipment status designs: two alphanumeric (tabular data), a schematic (iconic diagrams), and a combination alphanumeric-schematic. Task time and accuracy were analyzed using a repeated measures factorial ANOVA. The results showed the combination alphanumeric-schematic status design produced the best performance across task and information load conditions, while the alphanumeric designs produced the worst performance. Nevertheless, results suggest that all designs may be interchangeable for simplistic recognition and low loading tasks, but task complexity will favor a combination design for the final THAAD interface. |
