Exploring the impact of human-robot interaction on workers' mental stress in collaborative assembly tasks
Appl Ergon. 2024 Jan 5;116:104224. doi: 10.1016/j.apergo.2024.104224. Online ahead of print.ABSTRACTAdvances in robotics have contributed to the prevalence of human-robot collaboration (HRC). However, working and interacting with collaborative robots in close proximity can be psychologically stressful. Therefore, understanding the impacts of human-robot interaction (HRI) on mental stress is crucial for enhancing workplace well-being. To this end, this study investigated how the HRI factors - presence, complexity, and modality - affect the psychological stress of workers. We employed both the NASA-Task Load Index for subjec...

Intra-rater and inter-rater reliability of 3D facial measurements
Appl Ergon. 2024 Jan 4;116:104218. doi: 10.1016/j.apergo.2023.104218. Online ahead of print.ABSTRACTThree-dimensional (3D) body scanning technology has applications for obtaining anthropometric data in human-centered and product development fields. The reliability of 3D measurements gathered from 3D scans must be assessed to understand the degree to which this technology is appropriate for use in place of manual anthropometric methods. The intra- and inter-rater reliabilities of 3D facial measurements were assessed among four novice raters using 3D landmarking. Intraclass correlation coefficient (ICC) statistics were calcu...

Investigating effect of standardized total body skin examination using sequence-networks
This study employs sequence-network analysis to investigate the influence of instructing a standardized procedure on total-body skin examination (TBSE) performance. A between-subjects study was conducted with thirty-one participants comprising medical students and attending physicians. Among these participants, fifteen were randomly assigned to the uninstructed group and sixteen to the instructed group. The participants' gaze and field of view were recorded using eye tracking glasses while performing TBSE on a male and a female standardized patient. The recordings were then transcribed to depict the examination process. Th...

Evaluation of a 3M (mistakes, mentoring, and mastery) training program for transfer of control situations in a level 2 automated driving system
The objective of this study is to determine the effect of a novel, 3M (Mistakes, Mentoring, and Mastery) training program on drivers' behavior while using level 2 driving automation systems. To achieve this, 36 participants were assigned randomly to three different training programs (3M training, User manual, and Placebo) and drove through scenarios on a fixed-based driving simulator. The results showed that drivers in the 3M training group took back control more effectively when the driving automation system reached its limits compared to drivers who received User manual or Placebo training. Drivers in the 3M training Gro...

Muscle fatigue tracking during dynamic elbow flexion-extension movements with a varying hand load
Appl Ergon. 2023 Dec 30;116:104217. doi: 10.1016/j.apergo.2023.104217. Online ahead of print.ABSTRACTMuscle fatigue monitoring, an important element in a fatigue risk management process, can help optimize work intensity and reduce risks for musculoskeletal injuries. An experiment was conducted to determine whether myoelectric manifestations of muscle fatigue can reflect the pace of fatigue development associated with varying load intensity. Twenty male participants performed elbow flexion-extension movements with alternating hand loads (2 kg vs. 1 kg) for 16 min. The pace of fatigue in the biceps brachii in response to loa...

The effects of umbrella handle shape and grip type on muscle activation and postural variability under windy conditions
This study investigated how different shapes of umbrella handles and grip types influence muscle activation and postural variability under windy conditions. Seventeen adult participants were enrolled in this study, and different handle shapes (cylindrical, ellipsoidal, and triangular prism-shaped), grip types (four- and five-finger grip), and wind strengths were tested. Activation of the forearm and upper arm muscles was recorded using surface electromyography. Postural variability and ratings of (1) perceived difficulty of use and (2) perceived grip-posture variability were measured. The results indicated that activation ...
