“…The data could not be considered normally distributed due to the relatively small sample size. Two within-subject tests are commonly used for testing differences between conditions in human factors research if the assumption of normally distributed data is violated; Friedman's ANOVA is used for more than two categories and Wilcoxon signed-rank test is used for two categories (Willages 2007;Field 2009). Friedman's ANOVA only shows whether there is difference between the tested conditions, but does not show where this difference occurs.…”

Effects of coherent, integrated, and context-dependent adaptable user interfaces on operators’ situation awareness, performance, and workload

Nautical traffic management in The Netherlands is shifting from local traffic control to corridor traffic management. Current traffic management systems do not sufficiently support operators in perceptual and cognitive process to interpret and understand the large amounts of information needed for corridor traffic management. Newly developed user interface concepts aim to overcome deficiencies of current interface designs that insufficiently support situation awareness assessment. The effects of these new user interfaces, however, are insufficiently known due to the intricate relations between situation awareness, task performance, and workload. The objective of this study is to evaluate the effects of the three previously developed user interface concepts on operators' situation awareness, task performance, and workload to gain better insights into the benefits and limitations of the user interface design concepts. The effects were tested in a simulator environment. The results show that user interface features of an integrated user interface allowed operators to apply more effective information processing, which resulted in better task performance. Features of a context-dependent adaptable user interface triggered proactive behavior of operators, which resulted in better task performance for tasks in which operators require insight into future activities of the elements in the environment.

“…To evaluate the performance of the anti-sway system, two variables were selected to test: the first, with or without the anti-sway trajectory modifier; the second, with the The two types of experimental designs generally used in human factors testing are between-subjects and within-subjects designs [Wil07,Sel12]. In a between-subjects design, participants are each assigned to either a control group or to one of the test conditions; however, a large number of test participants are needed, and bias effects, such as skill using the USB gamepad, may not be eliminated when comparing the results of the different groups.…”

“…Confounding can also include other carry-over effects such as fatigue, cybersickness and motion sickness. To reduce the learning effect of confounding, a counterbalanced Latin-squares design will be utilized [Wil07] where, if four participants were to complete all four tests, each would complete the Table 6.1: The counterbalanced Latin-squares arrangement of the four tests.…”

Real-Time Operator-in-the-Loop Anti-Sway Control for Shipboard Cranes

Shipboard cranes play an important role in many maritime operations, however unexpected payload sway due to the motion of the ship or external disturbances creates a hazardous environment for deck personnel. To improve deck safety, the development of anti-sway control systems to reduce undesired payload motion has been of great interest to researchers; however, existing literature has focused primarily on sophisticated nonlinear control strategies that utilize simplified dynamic models, and the consideration of anti-sway control on high-fidelity, high-degree-of-freedom (DOF) crane/ship dynamic systems is lacking. Additionally, anti-sway control systems in the literature are typically developed with little consideration of real-time operatorin-the-loop interaction, and rarely are the human factors of shipboard crane anti-sway The author acknowledges the support and feedback from Dr. Rishad Irani of the Multi-Domain Laboratory at Carleton University, as well as the support of family, friends and peers throughout the development of this work.
