To design effective and efficient procedures and checklists, one must take into account the full operational context within which these procedures are embedded. This context is defined by the requirements of the technology, the limitations and capabilities of the human operators, and the constraints and affordances of the operational environment. The complexity of this context arises from the interactions of the human, machine, and environment. We present a model of that operational context, THE Model, that lays the foundations for analyzing each of these elements and their interactions, and illustrate its application through the analysis of an aviation accident.

Barshi, Immanuel, Degani, Asaf, Iverson, David and Lu, Peter J. (2012): Using Medieval Architecture as Inspiration for Display Design: Parameter Interrelationships and Organizational Structure. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 1799-1803.
In physical environments such as aerospace and process control, many system components and their associated information are interrelated (e.g., an increase in a chamber temperature results in an increase in its pressure). Displaying interrelationships between individual parameters and also among sets of parameters reveals meaningful information and can help yield understanding about the 'big picture,' which operators in complex systems commonly strive for. In this paper, we propose a framework for information organization, discuss a method for computation of such interrelations, and suggest a display organization approach to 'house' them. The computation is done using data mining tools and the display organization approach is based on concepts from Islamic medieval architecture. We illustrate these ideas using a helicopter engine display and briefly discuss some of the implications for a holistic display of multiple components and subsystems.

Goldman, Claudia V. and Degani, Asaf (2012): A Team-Oriented Framework for Human-Automation Interaction: Implication for the Design of an Advanced Cruise Control System. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 2354-2358.
We describe a teamwork framework to design human-automation interactive systems. Human automation interactions have been primarily considered as supervisory systems in which communication is seen as unidirectional. As systems become more complex, sophisticated, and autonomous, the opportunity for bidirectional cooperation between the human and machine becomes feasible and advantageous. To better understand bidirectional cooperation and develop computational tools we draw on concepts from philosophy, social psychology, human factors, and artificial intelligence to define 'team' and understand the requirements for efficient team interaction. We define several team properties such as mutual support, mutual commitment, machine transparency (state, behavior, control) and user transparency (state, intent, action) and responsiveness as a way to analyze and guide the design of human-machine interactions. We illustrated the applicability of the approach using a generic model of a full speed range adaptive cruise control and show the potential of this type of cooperative approach to human-machine interaction.

In this poster we present several methods for abstracting data into information and then integrating and organizing it for the purpose of display. We use an example from analysis of pilot-automation interaction to illustrate some of the underlying concepts.

Degani, Asaf, Palmer, Everett A. and Bauersfeld, Kristin G. (1992): "Soft" Controls for Hard Displays: Still a Challenge. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 52-56.
Future trends in design of controls and displays for cockpit sub-systems (electrical, pneumatics, fuel, etc.), will undoubtedly focus on replacing dedicated "hard" controls with reconfigurable "soft" controls depicted on the sub-system schematic display. This concept would allow for direct manipulation of mechanical components via the display. The case study reported here discusses the approach, redesign, and evaluation of soft controls and multi-functional displays for the Advanced Concepts Flight Simulator (ACFS), a two-engine, "generic" airliner. The redesign effort focused on the input interface (a touch sensitive screen), the display concept, and improving "navigation" among sub-system displays. The paper concludes with a summary of questionnaire data and comments of 26 airline pilots who flew a four-segment mission in the simulator. The subjective results indicated that pilots favored the direct manipulation concepts and the ability to link alerts, procedures, and configuration tasks. However, the technology used to support this concept still requires improvements.
