Heasly, Christopher C., Dutra, Lisa A., Kirkpatrick, III Mark, Seamster, Thomas L. and Lyons, Robert A. (1993): A User-Centered Approach to the Design of a Naval Tactical Workstation Interface. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. p. 1030.
“The 21st century Navy combatant ship will experience exponential increases in shipboard information to be processed, disseminated and integrated. High Definition System (HDS) technology will provide for the convergence of text, graphics, digital video, imagery, and complex computing to allow for a new range of advanced capabilities that exceed those of currently available workstations. These capabilities could result in unmanageable and overwhelming cognitive workloads for Navy tactical operators in CIC (Combat Information Center). For this reason, a prototype user interface was designed using future combat system requirements, proposed HDS capabilities, and human-computer interface design standards and principles. Usability testing of the prototype user interface was conducted as part of an effort to identify integrated information management technologies which reduce operator workload, increase human performance, and improve combat system effectiveness. This demonstration will focus on explanation and demonstration of future concepts envisioned for the AEGIS operational environment; organization and functionality of the menu structures and window contents; the usability testing methods utilized; results from usability testing; and plans for utilization of the prototype shell in other operational environments.”

Heasly, Christopher C., Dutra, Lisa A., Kirkpatrick, III Mark, Seamster, Thomas L. and Lyons, Robert A. (1993): High Definition Systems Usability Test Tool (HUTT): A Human-Computer Interface Prototyping Tool. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. p. 1040.
“The High Definition Systems Usability Test Tool (HUTS) was developed to demonstrate and assess different human-computer interface (HCI) concepts for generic operator console positions within an advanced naval tactical display environment. To facilitate a "rapid prototyping" approach to interface development, HUTT was developed as a general purpose tool. The HUTT can be used by the human factors engineer as a rapid prototyping tool enabling quick construction and evaluation of alternative interface concepts. Changes to the organization and operation of a prototype can be made quickly, ensuring that more time can be spent on evaluation as compared to development. The demonstration will focus on the uses and operation of the HUTT. Demonstration participants will be shown how to develop, install and modify the OSF/Motif compliant graphics (pull-down menu structure and window contents) and the functionality of the HUTT to reflect changes in interface concepts.”

Kirkpatrick, Mark, Perse, Randy M., Dutra, Lisa A., Creedon, Michael A. and Cohen-Mansfield, Jiska (1992): Development of a Memory Aid Design Concept for Older Users. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 175-179.
“This study was conducted to develop a design concept for an electronic memory device to enhance medication compliance in older users. The effort was supported by a Phase I Small Business Innovation Research (SBIR) grant from the National Institute on Aging (NIA). A user-oriented approach was used to develop a design concept for a memory device for older users. One hundred seniors were interviewed to identify their physical, physiological and cognitive capabilities and limitations, as well as their preferences for memory aid functions. Specific design requirements were gathered from user testing of six currently available memory aids with 30 of the original 100 elderly subjects. The interview and user testing results were consolidated to provide the basis for tradeoff criteria for memory and interface concepts, and for the development specifications for an optimal interface design for a memory aid designed specifically for the elderly user. A design concept was developed for a medication device that would be easy to use, would reduce the likelihood of scheduling errors, and would be non-threatening to older users who might otherwise be intimidated by an electronic device. The Phase I effort focused on enhancing medication compliance, which is a priority issue with the senior population.”

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.”
