Camouflage pattern features interact with movement speed to determine human target detectability.

Appl Ergon 2019 May 28;77:50-57. Epub 2019 Jan 28.

U.S. Army Natick Soldier Research, Development, and Engineering Center, Natick, MA, USA.

Applied ergonomics research examines not only the fit, form and function of military uniforms, but also their ability to effectively camouflage personnel as they perform job-related tasks. Many of these job-related tasks involve moving through environments, but existing literature examining camouflage effectiveness often assumes that movement effectively "breaks" even the best camouflage patterns, rendering them of limited utility for reducing the visual signature of a moving target. However, recent research demonstrates that animals equipped with adaptive camouflage change their patterning in predictable ways during movement and this adaptation decreases detectability, suggesting that uniform patterning may still hold value for reducing conspicuity during movement.

Department of Production Engineering, Federal University of Sao Carlos, Rod. Washington Luiz, km 235, 13565 905, São Carlos, Brazil.

Among the possible approaches for building virtual environments (VE), researchers have recently started employing game engines (GE). Although there are already studies reporting the usage of GE-based VEs, their potential for supporting a more comprehensive workspace analysis (considering the physical, organizational and cognitive aspects of work) has yet to be better understood. The main goal of this paper is to investigate how a GE-based simulation of a real workplace (a local control room in an oil refinery) can be used as a tool by practitioners and researchers in evaluating work conditions.

Appl Ergon 2019 May 10;77:16-21. Epub 2019 Jan 10.

Delft University of Technology, Faculty of Industrial Design Engineering, Landbergstraat 15, 2628 CE, Delft, the Netherlands. Electronic address:

Interferences during the boarding procedure are one of the main reasons of delay and increased turnaround time, becoming a relevant problem for airlines. Observations of the boarding process and questionnaires inside the aircraft revealed three main bottlenecks during the boarding process: (1) Hand luggage: Storage space is not sufficient and/or not used efficiently; (2) Preparation: Passengers are not well prepared for the boarding process; and (3) Communication: Audio announcements are unclear and unfocused. By translating these bottlenecks as possibilities for improvement, solutions were designed for the airport and aircraft interiors to reduce boarding time and improve the passenger boarding experience.

A hybrid human and organisational analysis method for railway accidents based on STAMP-HFACS and human information processing.

Appl Ergon 2019 Feb 1. Epub 2019 Feb 1.

Human Factors and Complex Systems Group, Loughborough University Design School, Loughborough University, Loughborough, LE11 3TU, United Kingdom.

Safety is a constant priority for the railway industry and there are numerous hazards in and around the rail system which may result in damage to train and environment, human injury and fatalities. Low levels of human and organisational performance have been shown to be a prime cause of railway accidents and a number of accident models and methods have been developed in order to probe deeper into the role played by organisational factors in accident causation. The Systems-Theoretical Accident Modelling and Processes (STAMP) method for example, represents a promising systematic and systemic way of examining sociotechnical systems such as the railway.

Appl Ergon 2019 Apr 13;76:73-81. Epub 2018 Dec 13.

Department for Social Science, International Research Institute of Stavanger - A Group Company of NORCE Norwegian Research Centre, Box 8046, N-4068, Stavanger, Norway. Electronic address:

With a scarcity of research on multiple working arrangements, the aim of the paper is to contribute empirical data from a Norwegian engineering, procurement, and construction enterprise that shed light on the challenges and benefits of a 14-21 working arrangement in itself and in relation to other working arrangements. We combine a sociotechnical system perspective with systematic content analysis using QSR NVivo, which reveals organizational complexity comprised of indirect, direct, positive, negative, and mutual interplays between various aspects of the enterprise, including processes and outcomes. We find that the 14-21 working arrangement, in combination with other factors of the work system, sets the premises for work processes and outcome factors that are both beneficial and challenging to individuals and the organization.

Eye-tracking reveals how observation chart design features affect the detection of patient deterioration: An experimental study.

Appl Ergon 2019 Feb 12;75:230-242. Epub 2018 Nov 12.

School of Psychology, The University of Queensland, St Lucia, Brisbane, Queensland, 4072, Australia; Clinical Skills Development Service, Metro North Hospital and Health Service, Herston, Brisbane, Queensland, 4006, Australia; School of Medicine, The University of Queensland, Herston, Brisbane, Queensland, 4006, Australia.

Particular design features intended to improve usability - including graphically displayed observations and integrated colour-based scoring-systems - have been shown to increase the speed and accuracy with which users of hospital observation charts detect abnormal patient observations. We used eye-tracking to evaluate two potential cognitive mechanisms underlying these effects. Novice chart-users completed a series of experimental trials in which they viewed patient data presented on one of three observation chart designs (varied within-subjects), and indicated which observation was abnormal (or that none were).
