A common stairway non-uniformity is the top-of-flight defect, where the rise and run dimensions of the uppermost step in a stairway differ from the subsequent lower steps. This defect has been described as hazardous, but its effect on foot placement and misstep risk in stair descent has not been studied. In this experimental study, we quantified foot overhang for adults (n = 27) descending a seven-step staircase with a top-of-flight defect compared to descending a uniform staircase. When the defect was present, an increase in foot overhang occurred on the third, fourth and fifth steps down the stairs (S3, S4, and S5; p &lt; 0.05), two to four steps below the step containing the defect (S1). Given that increased foot overhang is associated with an increased risk of misstepping and falling, this finding provides a biomechanical explanation for falls that originate downstream from the defect and in a region of the stair where the geometry is uniform. Our findings provide support for requiring uniform stair geometry beginning at the upper landing, a common area where stair dimensions change in both new and existing construction and renovations.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"132 ","pages":"Article 104695"},"PeriodicalIF":3.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571725","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}

It explores how automation reconfigures the balance between human, technological, and organisational elements, with a focus on operator roles. Drawing on an explorative case study in an open-pit mine, the analysis applies Balance Theory to interpret how work and organisational relations are reshaped as autonomy is redistributed between humans and technology. Findings show that while the AHS contributes to improved safety and predictability, it also introduces greater work-task diversity and responsibility, increased standardisation and bureaucratisation, and reduced social interaction with emerging risks of isolation. Operators remain central to supervision, coordination, and adaptation, but their work becomes more procedural and dependent on organisational structures and formal routines. The study concludes that maintaining balance in cyber–physical mining systems is an ongoing organisational responsibility that relies on social cohesion, mutual trust, and continuous learning. Ultimately, the findings emphasise that the effectiveness of mining automation depends as much on collective engagement and organisational adaptation as on technological performance.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"132 ","pages":"Article 104684"},"PeriodicalIF":3.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145607517","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}

For potential passengers of these systems, new situations may arise, leaving them without a driver to directly communicate with. This can be problematic when the driving automation is confronted with situations it might be unable to manage by itself, which would cause a minimal risk maneuver (MRM), e.g. a complete standstill of the vehicle. Some concepts enhance these systems with a remote assistant who can support the HAV, adding novelty to the transportation process. This increased novelty may result in user discomfort for passengers, causing a need for information systems that address this. One possibility to do so and to thus improve hedonic quality and thus comfort for passengers is by providing system transparency via a media rich in-vehicle Human-Machine Interface (iHMI), which provides information to passengers about the ADS and its processes. However, there is still a gap in research on the ideal communication mechanism to ensure good hedonic quality and comfort during these situations. We conducted a simulator study in virtual reality (VR), investigating interfaces based on media richness theory to address this issue. The interface provided a multi-layered iHMI consisting of transparency information presented with varying levels of media richness. In a block design, participants experienced three versions of an iHMI, one presenting information via text, another combining text and auditive presentation and a third adding a human avatar simulating Face-to-Face communication. After each scenario, participants completed questionnaires regarding understanding, predictability, trust and user experience. Study results reveal significant increases in the hedonic quality of user experience and trust towards the system for interfaces with increased media richness, providing a first step towards enhancing user comfort with iHMI in automated mobility systems during challenging situations for the automation system, such as MRM.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"132 ","pages":"Article 104697"},"PeriodicalIF":3.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571727","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}

In addition, current lighting standards place greater emphasis on the role of ambient lighting and wall (il)luminance in creating a comfortable environment. However, higher luminance levels do not inherently lead to enhanced reading comfort. Prior research indicates that reading comfort is influenced by a combination of monitor luminance and the luminance characteristics of the surrounding environment. This study examines the optimal monitor luminance levels that enhance reading comfort under fixed wall luminance conditions, as well as the optimal wall luminance levels under fixed monitor luminance conditions. A total of 25 participants (aged 21–26 years) took part in the experiment. Using the psi-marginal adaptive method, participants were given direct control to determine the luminance levels they perceived as most comfortable for reading. Four different monitor luminance levels (120, 260, 453 and 700 cd m⁻²) and five wall luminance levels (12, 34, 68, 113 and 170 cd m⁻²) were used as fixed luminance levels throughout the experiment. The results demonstrate that higher fixed wall/monitor luminance levels are generally associated with higher optimal monitor/wall luminance levels selected by participants. According to the European standard of lighting requirements for indoor workplaces, the minimum required wall luminance is between 24 cd m⁻² and 38 cd m⁻². For a fixed wall luminance level within this interval (34 cd m⁻²), the results of this study show that the optimal luminance level of the monitor ranges from below 120 cd m⁻² to around 450 cd m⁻² with a median of 166 cd m⁻², and an IQR of [133 cd m⁻²; 270 cd m⁻²]. In conclusion, the findings suggest that, within standard office environments, it is not necessary to utilise monitors with luminance levels exceeding 500 cd m⁻² to achieve optimal reading comfort.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"132 ","pages":"Article 104679"},"PeriodicalIF":3.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145449029","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}
