Investigation of eye movement measures of mental workload in healthcare: Can pupil dilations reflect fatigue or overload when it comes to health information system use?
Appl Ergon. 2023 Oct 31;114:104150. doi: 10.1016/j.apergo.2023.104150. Online ahead of print.ABSTRACTThe use of health information systems (HIS) can result in high workloads and, consequently, poor performance characterized by e.g. increased occurrence of errors among clinicians. Pupillometry offers a good possibility to measure mental workload in a dynamic work setting. Currently, there is a lack of empirical research in the context of healthcare settings. Therefore, the aim of the present study was to examine whether specific eye movement measures are suitable for measuring mental workload in the healthcare setting, espe...

Influence of an upper limb exoskeleton on muscle activity during various construction and manufacturing tasks
In this study, the influence of an upper limb exoskeleton on muscle activity was investigated experimentally for three commonly performed tasks in the manufacturing and construction sectors. The tasks tested were overhead assembly, bricklaying, and box moving tasks. Eighteen males participated in the tests. The results showed a reduction in shoulder flexor muscle activation during all three tasks (up to -45.46 ± 4.52% for the anterior deltoid), but increased extensor activation (up to 15.47 ± 8.01% for the latissimus dorsi) was observed when the task was not primarily performed above shoulder level. The results revealed ...

Modeling novice law enforcement officers' interaction with in-vehicle technology
The objective of this study was to develop a cognitive performance model for novice law enforcement officers (N-CPM) to model their performance and memory load while interacting with in-vehicle technology. The model was validated based on a ride-along study with 10 novice law enforcement officers (nLEOs). The findings suggested that there were no significant differences between the N-CPM and observation data in most cases, while the results of the benchmark model were different from that of N-CPM. The model can be applied to improve future nLEO's patrol mission performance through redesigning in-vehicle technologies and tr...

Following car reduces motorcycles' size-arrival effect: A study using online experiments
Appl Ergon. 2023 Oct 22;114:104153. doi: 10.1016/j.apergo.2023.104153. Online ahead of print.ABSTRACTMany fatal motorcycle accidents occur because car drivers infringe on motorcycle riders' right-of-way. The size-arrival effect refers to observers' tendency to judge larger objects as arriving sooner than smaller objects when estimating an approaching object's arrival time, which is one cause of right-of-way motorcycle accidents. Previous research has focused on a single vehicle that approaches the driver. However, it is also possible that a motorcycle approaches a driver along with other vehicles driving on multiple-lane r...
