“…Yet, human experience and intuition may be required whenever the diagnostic process (i.e., recognizing that there is a problem and identifying the source of the problem) and the associated decision-making process (i.e., deciding how to handle the problem) cannot be fully automated. Thus, the human operator may sometimes be required to view and handle information of individual events in real time or close to it in order to perform supervisory tasks such as fault diagnosis and handling (e.g., Brann et al 1996, Thronesbery andSchreckenghost 1998).…”

There is often a need to display logged information textually for real-time event-based supervisory tasks. Textual display design can follow several directions that reflect a tradeoff between a visual load and an operational load. The study reported here was designed in order to examine this tradeoff and its implications for such display design. An eventbased monitoring and handling task was used with different event types having either a high or a low handling priority. The events were presented in four different display configurations varying in their degree of visual and operational load. The specific performance indices were event dwelling times, event handling proportion, and handling errors. In general it was found that the high priority events were handled faster and more accurately than the low priority events. In addition, performance with the various display configurations was dependent upon event type. These findings are discussed in terms of visual vs. operational load tradeoff and its contextsensitivity. Some implications for display design and further research on event presentation approaches are discussed.

“…As part of the life support systems control application development, we have made recent progress toward adding this 4 th layer to the 3T architecture [11]. Capability added to support building the interaction layer includes (1) communication protocols and software to exchange information between the sequencer and a graphical interface process, (2) a principled approach for designing autonomous control software that supports human interaction, and (3) reusable software for building a application graphical interfaces.…”

Managing life support for remote facilities requires maintaining environmental conditions beneficial to humans and plants, and managing resources like water, product gases, and food. Appropriate allocation and coordination of these tasks among humans, robots, and life support systems is important for efficient operations. The need for operational flexibility and reactivity combined with the need to reduce crew workload and the high cost of failure to manage resources effectively suggests automating low level control tasks and assisting humans in strategic planning and resource management. The three tier (3T) layered architecture is well-suited for such automated control. The planner automates task coordination across subsystems contending for resources. The separation of deliberative tasks from reactive tasks enables appropriate human intervention in autonomous operations. At each tier, mechanisms are provided for flexible response to novel events. We demonstrated the effectiveness of 3T to control life support systems for NASA's Lunar/Mars Life Support Test Project.
