    Operators could easily be overwhelmed by the enormous amount of data generated by today's increasingly complex systems. An operator of a very large facility, for example, might scan through displays of numerous floor plans or hundreds of thousands of lines of text, but since the typical human mind “cannot absorb pure data” (de Bono, 1980), a next-generation interface is needed that pav...

    Pilots and operators of advanced military systems need better ways of interacting with their systems, including more efficient human-machine dialog and better physical interface devices and interaction techniques. The goal of the Eye/Voice Mission Planning Interface (EVMPI) research is to integrate voice recognition and eye-tracking technology with aviation displays in order to reduce the pilot's ...

    The tests were designed to provide evidence of differences among the perceptions of ease of use among professionals, semi-professionals, and non-professionals before and after a major computer information system is installed. The results of the tests show that the perceptions about the computer system were very stable over the 15 month implementation period for all employees, particularly professi... View full abstract»

    One of the key elements in the design of a cooperative decision support system (with a human and an automated system jointly working toward a solution) is the information visualization requirements. A variety of research efforts have shown how typical automated systems tend to remove the human partner from the decision-making role and into a supervisory role. However, enhanced visualization tools ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (524 KB)

    An interface whereby brain responses can control machines has been developed by the Armstrong Laboratory. This EEG-based control uses the magnitude of the steady-state visual evoked response (SSVER) as a control signal. The SSVER is identified and monitored using non-invasive scalp electrodes and advanced signal processing technology. With biofeedback, users learn to increase or decrease the magni...

    Traditionally, anomaly response and disturbance management have been studied in the context of a group mind, where a small homogeneous group of practitioners who are co-located work together to respond to system disturbances and anomalies. We have extended these studies by exploring the processes of dynamic fault management in the context of space shuttle mission control, which consists of a large... View full abstract»

    The flexible constellation of technologies that comprise virtual environment (VE) systems provide many new opportunities for training. However, the lessons learned from decades of research in flight and driving simulation seem largely forgotten. This review recalls a set of long-term issues that will constrain the application of VE systems to training. In particular, the issues of cost effectivene... View full abstract»

    Historically, a significant number of accidents in complex systems have been attributed to a lack of situation awareness (SA). Despite increased use of automation and improvements in display design to improve SA, re-design is unable to completely eliminate accidents of these types. One viable option is to train operators to acquire and to maintain situation awareness. We propose employing expert k... View full abstract»

    The US Air Force (USAF) is in the midst of an information revolution that requires thoughtful consideration of (1) cooperative problem solving, (2) emergent complexity, and (3) changing paradigms. Not only is the information revolution evident in the technology that proceeds from it (e.g. virtual reality systems, ubiquitous computing, groupware) but it is having a deleterious affect on the human's...

    Analyzing the cognitive tasks of operators of future novel systems in order to provide design guidance represents a major challenge to cognitive systems engineering. Cognitive task analysis based on extant systems may not adequately reflect operator tasks after radical organizational and technical change. We describe the results of an effort to analyze a proposed, highly automated system for patie... View full abstract»

    Complexity is only one of the many factors that influence the design of human interaction with complex systems, but it is extremely important. Depending on where and how it is instantiated and whether it is real or apparent, the user may perceive and deal with it differently. Successful user-system interaction becomes contingent on the user's capabilities and degree or extent of mental involvement... View full abstract»

    With advances in computer technology, complex applications are being developed which involve multi-window operations. With the increasing number of windows on the desktop, effective viewing of all the necessary information for a task becomes difficult. A significant portion of the user's time is spent in opening/closing or moving/resizing the windows. Since these window interface housekeeping acti... View full abstract»

    This paper discusses several general research and development issues that the authors view as critical to the design of adaptive interfaces for future US Air Force crew stations. Its major intent is to propose and describe three classes of variables and events that are considered to be potentially useful “triggers” for the introduction of functional adaptations to crew station displays...

    The tau hypothesis predicts that observers initiate collision avoidance actions based on an integration of speed and distance. We constructed an experiment to test whether human subjects are sensitive to the critical boundary of imminent collision, even when this boundary is not defined by an integration of speed and distance. Subjects were asked to perform a simulated flight towards a barrier sur... View full abstract»

    In an effort to understand the nature of perceptual expertise in laparoscopic surgery, we interviewed 20 surgeons, using videotape footage of a challenging laparoscopic gallbladder removal case. Early data analysis showed that certain perceptual cues along with accepted surgical methods were important for supporting the confidence level needed to proceed laparoscopically when risk was present.

    Natural language timing (NLT) is a complex human attribute and an integral part of complex human activities. To effectively participate in real time interactive voice to voice communication, intelligent systems must acquire this complex attribute. The human perceptual diversity in interpretation of NLT was hardly a source of technical concern until recent trends in communication technology. The pr... View full abstract»

    System design involves a series of tradeoffs. The benefit of one design technique will impact the benefits of another. Developers must weigh the advantages and disadvantages of each approach in order to design the system that is most suitable for the end user. Studies have been performed to determine users' preferences for various system designs. In particular, studies have shown that menu selecti... View full abstract»

    Distribution of tasks among different operational phases of complex human-machine systems is proposed as a means to balance operator's workload over the operation cycle. The objective of this approach is to enable novice users to bring forward the execution of predictable tasks. This approach is motivated by the observation that expert user can indeed anticipate a situation so as to bring forward ... View full abstract»

    This paper describes a workload model as a function of the system complexity and task difficulty. The workload index derived is general to the various dimensions of workload measures, task dynamicity, and instabilities associated with the system of interest. We show that the variations in workload changes as the system and task parameter change View full abstract»
