We conducted an exploratory investigation of a commercial postural feedback system, which provided auditory and vibrotactile feedback following excessive trunk motion, in vehicle manufacturing. Eight workers used the system during regular shifts for up to 10 workdays. We observed a reduction in “poor” postures on the first day of feedback. However, these benefits diminished over time, possibly due to a novelty effect—with improvements diminishing as participants adapted to the system—and effects varied greatly across participants.

Findings from this exploratory study suggest the importance of enhancing postural feedback system design to sustain behavioral change over time and better support individual needs.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"128 ","pages":"Article 104564"},"PeriodicalIF":3.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These tasks replicated real conditions that they might encounter during actual missions. The results indicated that there was a significant difference in participants' mental workload under different tasks, primarily reflected in subjective perceptions and physiological data. Mental demands emerged as the most substantial contributor to perceived workload. As task changes (for example, introducing time limits and needing to avoid collisions with other vessels), participants' fixation duration and revisit counts for Areas of Interest (AOIs) increase. Participants showed a greater focus on AOIs that provided external information. Despite the increase in mental workload, participants' performance did not decline. The findings of this study can be applied to navigation training and bridge design, such as optimizing information presentation methods and developing stress management strategies to enhance navigational safety.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"128 ","pages":"Article 104560"},"PeriodicalIF":3.1,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results revealed a mismatch where participants in the automated condition reported greater situation awareness but demonstrated significantly slower hazard recognition, with this performance deficit consistent across both anticipation and surprise hazards.

However, in industrial scenarios, workers’ biomechanics are assessed mainly through questionnaires and scales which provide limited objectivity. Very few studies analyzed the biomechanics of workers in multiple sessions, and no study assessed diverse populations of workers. Therefore, we collected tracking data from 14 neurotypical and 7 participants with autism spectrum disorder (ASD) performing assembly tasks in a lab-based industrial collaborative workcell. Human tracking data were acquired by an Azure Kinect and elaborated with a biomechanical model that allowed to compute human kinematics and dynamics. The biomechanics of neurotypical and ASD operators were compared across two working sessions. Both neurotypical and people characterized by ASD decreased torque and power in the second session with respect to the first one, indicating adaptation to the working activity. Interestingly, ASD people expended more energy than neurotypical, suggesting a higher risk of fatigue. Overall, ASD people performed similarly to neurotypical people from a biomechanical point of view. In this study, we showed a protocol for multisession biomechanical monitoring of workers during industrial human-robot collaboration tasks that can be employed in real scenarios and with ASD workers. This approach can be useful in human-robot collaboration to design minimum-fatigue collaborative tasks, support physical health, and improve ergonomics for workers.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"128 ","pages":"Article 104557"},"PeriodicalIF":3.1,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the effects of 3D imaging for professional screeners in HBS, where the screening task is to detect bombs in pre-alarmed bags flagged by automated explosives detection systems. In our study, 51 professional screeners completed a highly realistic HBS task involving two levels of bag complexity in 2D and 3D imaging conditions with the same image quality. We found that 3D imaging resulted in higher detection performance in terms of hit rate and sensitivity (d’ and d_a, two sensitivity measures of signal detection theory).
