Orden, Karl F. Van, Benoit, Sandra L. and Osga, Glenn A. (1994): Adrenergic Stress and Performance on a Command and Control Task. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. p. 991.

“Performance on a simulated antiair (AAW) and antisurface-ship (ASUW) warfare task was examined as a function of task-independent cold air-induced adrenergic stress. Twenty subjects, trained and experienced in modern naval warfighting systems, completed the study. The 54-minute scenario task required subjects to seek out information on a tactical display regarding the appearance of new symbols, respond to questions regarding general symbol recognition, and respond to questions concerning specific, scenario dependent, symbol characteristics. Near the conclusion of the scenario, subjects were also ordered to fire missiles at designated targets and to fire missiles at targets of their own choosing. Performance on the task was recorded while subjects were exposed to room air temperatures of either 22{deg}C or 4{deg}C. The cold exposure paradigm produced an adrenergic stress response -- as indicated by significantly elevated pulse and norepinephrine levels. Results showed task performance was nearly identical for both groups for the scenario as a whole. However, during a 12-minute portion of the scenario when hostilities were simulated, the ambient and cold stressed groups demonstrated divergent behavioral response patterns; stressed subjects were more liberal with missile fire, and more conservative in their responses to the scenario dependent questions. The responses to the symbol recognition questions during the hostilities portion of the scenario were equivalent for both groups. These results are indicative of a shift in the allocation of cognitive resources as a function of adrenergic stress, and have implications for the development of complex human-machine interfaces.”

Kirkpatrick, Mark, Dutra, Lisa A., Lyons, Robert A., Osga, Glenn A. and Pucci, John J. (1992): Tactical Symbology Standards. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1087-1091.

“CRT displays aboard U.S. Navy ships use a standardized monochrome Naval Tactical Data System (NTDS) symbol set to represent properties of symbols such as platform type (e.g. Aircraft Carrier, Combat Air), environment (e.g. air, surface, subsurface), and identification (e.g. hostile, friendly). A color symbol set has been proposed in NATO Standardization Agreement 4420, Display Symbology and Colours for NATO Maritime Units (1990). The U.S. Navy is currently considering ratification of this Standardization Agreement (STANAG). Empirical comparisons of operator performance using the NTDS symbology versus those using the color-filled NATO STANAG symbology were conducted. Two additional experimental symbologies were also created. The first, called NTDS Equated, is a color version of the NTDS symbol set, and the second experimental symbol set, called NATO Outline, is a color outline version of the color filled NATO STANAG symbol set. Test subjects were asked to find (hook) specific symbols during a tactically relevant scenario. Time to the first correct hook and percentage of correct hooks were subjected to analyses of variance (ANOVA). Experimental results revealed that the NATO STANAG symbol set outperformed all other symbol sets in terms of symbol recognition time, and outperformed the NTDS Standard symbol set for symbol recognition accuracy as well. The results indicated that tactical information can be transferred more quickly and accurately to watch standers through effective use of symbol coding. Test subjects familiar with the NTDS symbology expressed a preference for the color symbol sets in opinion surveys administered after the experiment. General conclusions resulting from comparisons across symbol sets were that color fill was more effective than color outline, and that operator performance gains were achieved as a result of color coding and greater information content on the symbol. This paper presents the human performance assessment that was conducted, the results, and the implications of the findings for ratification of NATO STANAG 4420.”

Osga, Glenn A. (1989): Human Factors Issues in Future Navy Workstation Development. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1077-1078.

“The 1990's will present several challenges for human factors in the research, development and deployment of surface navy systems. For several ship classes, Arleigh Burke (DDG-5l) Destroyers, AEGIS Cruisers and NATO Frigates, new workstations and upgrades are planned. These system upgrades present several windows of opportunity to the Navy for improvements in human engineering. This symposium addresses the scope and nature of several research challenges demanding results from human factors. These results must be prepared to address design questions as early as 1991-1992, to influence workstations to be fielded in the mid to late 1990's.”

Osga, Glenn A. (1989): User-Computer Interface Issues for Future Ship Combat Consoles. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1079-1083.

“As we approach the 1990's the surface navy is facing critical procurement decisions for the design of consoles for shipboard combat information centers. Studies are being conducted to identify the impact of current designs on performance, and to construct and test prototypes for future designs. The goal is to develop guidelines for future consoles which are performance based and which will guide both near and long-term design strategy. A methodology is being applied which incorporates job description, procedural simplification, and display re-design. Although much progress has been made, and potential design improvements identified for a single user-type in an anti-air warfare capacity, the scope of this effort leaves many design questions unanswered for the numerous types of combat information center operations and personnel.”

Osga, Glenn A. (1989): Procedure Modeling and Performance Prediction for Navy Surface Ship Consoles. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1084-1088.

“Very little human performance data has been collected for current navy shipboard consoles. This project identified a source of user behavioral data through the reduction and analysis of data captured with the Aegis shipboard data extraction programs. The data was used to construct a preliminary human performance database for a combat team. This database was used as input to a procedural network model, providing an analysis tool which allows task construction and performance prediction without the difficulty associated with acquiring ship or land-based combat system time. The database and models are currently being evaluated for their predictive validity.”
