Murphy, Elizabeth D., Reaux, Ray A., Stewart, Lisa J., Coleman, William D. and Harwood, Kelly (1989): Modeling Air Traffic Controller Performance in Highly Automated Environments. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 47-51.

“As increasing levels of automation are planned for the United States' air traffic control system, there is a need to assess planned system design changes for their potential effects on human performance. The model of controller performance developed by this work permits the comparison of prior and planned system transition states on several performance dimensions: perceptual, analytic, response, and resource management. Systematic predictions of performance provide a basis for identifying potential trouble spots in a planned system. The model can be employed to determine whether system design changes will improve controller performance without placing unreasonable demands on the controller's resources. It can be tailored to represent human performance variables and sources of resource demand in any complex automated system.”

Reaux, Ray A., Murphy, Elizabeth D., Stewart, Lisa J., Gresh, Janet L. and Bruce, Karin (1989): Building a Modeling and Simulation Analysis Tool to Predict Air Traffic Controller Workload and Performance. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 52-56.

“To meet expected increases in domestic air traffic, the Federal Aviation Administration (FAA) will increase the level of automation in the domestic air traffic control (ATC) system. There is a need to assess the effects of the increased automation on controller workload and performance. Software-based engineering tools are needed to automate the analysis, allowing designers to identify potential problems early in the system design lifecycle. This paper describes one such tool, the Predictive Air Traffic Controller Analysis Model (PATCAM), a modeling and simulation analysis tool that uses a system operations concept and task attributes database, a controller activities model, a sector environment model and simulation engine, and a workload or performance model to predict the impact of system design changes on controller workload or performance.”

Reaux, Ray A., Griffin, Thomas J. and Lewis, Ruthan (1989): Usability Testing and Requirements Derivation for EMU-Compatible Electrical Connectors. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 144-148.

“On-orbit servicing of payloads is simplified when a spacecraft has been designed for serviceability. A key design criterion for a serviceable spacecraft is standardization of electrical connectors. The following research investigated the effects of extravehicular mobility unit (EMU) glove size, connector size, and connector type on usability of electrical connectors. An experiment was conducted exploring participants' ability to mate and demate connectors in an evacuated glovebox. Independent variables were two EMU glove-sizes, five connector size groups, and seven connector types. Significant differences in performance times and heart rate changes during mate and demate operations were found between EMU glove sizes, among connector types, and connector sizes. Subjective assessments of connectors were collected from participants with a usability questionnaire. The data were used to derive design recommendations for a National Aeronautics and Space Administration (NASA) recommended EMU-compatible electrical connector.”

Reaux, Ray A. and Williges, Robert C. (1988): Effects of Level of Abstraction and Presentation Media on Usability of User-System Interface Guidelines. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 330-334.

“User-system interface (USI) guidelines are emerging as a tool for user interface design. The roles of levels of abstraction (concrete and abstract) and of guideline presentation medium (hard copy or on-line) on detection of USI guidelines violations in user-system interface evaluation were investigated. Overall, less than 50% of the guideline violations were detected by software engineers. Abstract guideline violations were more difficult to detect than concrete guideline violations, and on-line presentation resulted in relatively higher guideline usage during evaluation than hard copy presentation. It was concluded that improvements in USI guideline form and media are required to make guidelines a more useful USI design tool.”
