Research into the effect of automation on human multitasking performance is primarily focused on Decision Automation (a machine suggesting a certain course of action for a human operator to take) and Action Automation (a machine carrying out a certain course of action on behalf of the human operator) while Acquisition...
This project studied how a user's handedness affects his or her ability to use a
special-purpose handheld digital device such as a digital camera or rangefinder. More
specifically, it sought to identify how handedness affects speed and accuracy when
navigating within a menu system. 24 participants were given 8 menu...
Human operator performance was evaluated using two
types of displays in a simulated ocean surveillance task.
The two types of displays studied included a display in
which position uncertainty information was given (polygon
display) and a display in which uncertainty was not
explicitly shown (line display). The experimental task
Statistically, travel by air is one of the safest forms of transportation. Yet we
continue to experience aviation tragedies. Do we fully understand flight safety or is
there another way of looking at the problem? In this work a new way of approaching
the question of flight safety is developed,...
The flightcrew of a modern airliner operates in a multi-tasking environment with
several tasks competing for the same attentional resources at the same time. Too many
tasks vying for the crew's attention concurrently imposes a heavy workload on the
flightcrew. This results in the satisfactory execution of some tasks at...
Many failures of interpersonal communication and coordination in the aircraft
cockpit have been found to occur as a result of poor management of flightdeck 'resources'.
Crew Resource Management (CRM) is a concept that has evolved within the aviation
community to specifically address this issue of resource management.
The concept of...
Emergency stop controls are essential parts of industrial machinery because they
are designed to stop the operation in case of emergencies without risks to operators,
equipment, products, or facilities. Current guidelines for emergency stop controls have
been formulated based on experience but not on empirical studies.
The main objectives of...
Task Management (TM) refers to the function in which the human operator
manages his/her available sensory and mental resources in a dynamic, complex, safety-critical
environment in order to accomplish the multiple tasks competing for a limited
quantity of attention. There is reason to believe that the level of automation on...
Research in the aviation domain, driving distractions, anesthesia
administration, and nuclear power plant control rooms show that Concurrent Task
Management (CTM) is a process that every human operator performs when
interacting with complex environments. The need for understanding concurrent task
management in a broader perspective more applicable and generalizable to...
The cockpit is an environment in which many important tasks simultaneously
compete for pilot attention. Cockpit Task Management (CTM) is the process by
which pilots selectively attend to flight tasks in such a way as to safely and
effectively complete a flight. CTM has been categorized as a mental function...
