Greetings
In this week's Cognitive seminar we have the tremendous pleasure of welcoming Dr. Robert McCann (NASA Ames Research Center) to the University of Waterloo for a talk titled:
Modeling Eye Movements in a Spacecraft Cockpit
(abstract below)
The seminar will be held from 2:30-4:00 pm in the PAS building, room 3026 (ABC Room). All are welcome to attend.
Have a nice day,
Evan

Abstract
During a dynamic phase of spacecraft flight, such as launch, ascent, or entry, operators must examine primary flight display indicators on a regular basis to maintain situation awareness of rapidly changing parameters such as vehicle velocity, position, and altitude. If an onboard system experiences a mission-threatening fault or malfunction, however, operators must time-share their flight indicator processing with multiple additional sources of visual information (e.g., printed text, digital sensor values, graphical indications on system summary displays, etc.) to diagnose the malfunction and complete recovery procedures. Recent studies of operator behavior in ground-based simulations of spacecraft ascents revealed high levels of inter-operator variability in fault-related task completion times that most existing human performance modeling tools are too deterministic to simulate. We addressed this modeling deficiency by combining the activity-scheduling capabilities of APEX, a state-of-the art multitasking human performance-modeling tool, with a Human Oculomotor Performance (HOP) module that generates fixation sequences and fixation durations stochastically. The resulting set of model-derived fault-management task completion times spanned the full range obtained in human-in-the-loop testing. However, model-based task completion times were slower than for humans, and detailed analyses of human eye movements revealed several differences between human and model fixation quantities, information-sampling choices, and time-sharing strategies. These discrepancies can be used to guide future modifications to the model to better simulate spacecraft operator performance. The benefits of an improved modeling tool for future spacecraft design and real-time operational assistance will be discussed.
