Sleep quality and comfort in fully automated vehicles: A comparison of two seat configurations
Appl Ergon. 2023 Sep 14;114:104137. doi: 10.1016/j.apergo.2023.104137. Online ahead of print.ABSTRACTAs autonomous driving technology advances, the possibility of using vehicles as sleeping environments becomes increasingly relevant. To investigate the feasibility of this concept, a sleep study was conducted with twelve participants who were given a 4-h opportunity window to sleep in both reclined and flat seat configurations. The evaluation involved both objective measures, including polysomnographic (PSG) data analysis, and subjective measures through questionnaires, assessing sleep quality and comfort. While the sleep q...

Assessing the impact of industrial glove use on perceived hand dexterity, function, and strength
This study quantifies the impact of three styles of industrial metacarpal gloves on dexterity, gripping, pinching, and torquing tasks. Results indicated that wearing metacarpal gloves duplicated the time to complete a dexterity task from an average of 57 s for bare hands to 127 s for gloved hands. The highest drop in gripping force occurred while wearing a thicker glove, while gloves with thinner palmar sides produced smaller but similar force reductions of around 6%. The highest pinching force was obtained while wearing the thinnest glove, with a rise of 15%. Self-perception of exertion while wearing gloves varied between...

Identifying firefighters' situation awareness requirements for fire and non-fire emergencies using a goal-directed task analysis
Appl Ergon. 2023 Sep 14;114:104136. doi: 10.1016/j.apergo.2023.104136. Online ahead of print.ABSTRACTA firefighter's situation awareness (SA) is considered crucial to making effective tactical decisions and actions at the scene. Despite the importance of the firefighter's SA, there have been limited research efforts to understand what cues and information firefighters use to assess ongoing situations and predict future conditions. In addition to fire events, contemporary firefighters respond to an increasing volume of non-fire incidents. Thus, this study aims to identify firefighters' SA during three fire incidents (single...
