Advanced sensing, decision-making, and control systems in autonomous vehicles offer promising opportunities to mitigate MS in next-generation transportation. Traditionally, objective metrics such as Motion Sickness Dose Value (MSDV) and Motion Sickness Incidence (MSI) are derived directly from vehicle motion states to quantify MS severity. However, these metrics often overlook the filtering or amplification effects of human body dynamics on the motion stimuli experienced in occupant heads. To address this, we designed two motion planning algorithms to generate vehicle trajectories: one optimized solely based on vehicle motion (control group) and another incorporating occupant head motion dynamics (experimental group). Real-road experiments with 23 participants, using a within-subject design, were conducted on an automated vehicle. Results demonstrated that trajectories with ‘head-motion-first’ concept can significantly reduce MSDV, with subjective assessments via the Misery Scale (MISC) showing notable reductions in MS severity.

The 2D screen may add cognitive load, reducing VR usability, especially in users suffering from mental health issues such as depression. These 2D screens might further reduce the therapy outcomes if they affect users' situation awareness (SA) and engagement. Many mental health professionals are not fully aware of the benefits or potential applications of immersive VR therapy. This study aims to evaluate the potential benefits of more immersive technologies, such as VR, using head-mounted displays (HMDs). As a first step towards potential clinical implementation, we ran an experiment with 21 healthy participants who performed a 3D reaching and cutting fruit task using: (1) a VR HMD, and (2) a 2D screen. Pupil diameter, fixation, saccade duration, and saccade amplitude data were collected. Pupil diameter results showed that the VR environment can mitigate the impact of high task difficulty on participants’ cognitive workload (CWL). Fixation and saccade results indicated that participants could tentatively maintain consistent levels of SA and engagement within the VR environment, regardless of task difficulty. These findings suggest that VR holds promise as a therapeutic platform for alleviating CWL and maintaining engagement compared to 2D screens.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"134 ","pages":"Article 104720"},"PeriodicalIF":3.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145928137","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}

One area that needs more attention is understanding the effects of displaying AV self-assessed system certainty – regarding its navigability around roadway obstacles – on drivers' trust, decision-making, and behavioral responses. To contribute to the existing body of work, the current study evaluated a set of dynamic and continuous human-machine interfaces (HMIs) that present 2-dimensional AV system certainty information to drivers. A simulated driving study was conducted wherein participants were exposed to four different linear and curvilinear system certainty patterns (Linear Up, Linear Down, Convex, and Concave) on an HMI that represented an AV's confidence in its ability to safely avoid a construction zone ahead in its lane. Using this information, drivers decided whether or not (and when) to take over from the vehicle. The AV's true reliability and system certainty were not directly proportional to one-another. Trust, workload, takeover decisions and performance, eye movement behavior, and heart rate measures were captured during the study to understand drivers' responses to the vehicle certainty information. Overall, system certainty information had a significant effect on drivers' takeover response times and eye gaze behavior but did not affect their trust nor workload. In 24 % of all cases, participants either voluntarily took control of the AV when it was reliable or did not take over when the AV was unreliable. Trust was higher for participants who did not take over. The results of this work can be used to inform the design of in-vehicle interfaces in future autonomous vehicles, aiming to enhance decision-making and safety during driving.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"134 ","pages":"Article 104719"},"PeriodicalIF":3.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145928135","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}

This framework extends the author's previous work on human-machine-environment-procedure (HMEP) taxonomy through the application of Rasmussen's Risk Management Framework (RRMF), which can serve as a common framework to aggregate or compare datasets collected by different organizations. This RRMF-based HMEP taxonomy was used to categorize the contributing factors of 30 technical failure occurrences into seven mutually exclusive categories and respective subcategories for statistical analysis and other risk management analysis. The RRMF provided a hierarchical structure for these first-layer categories, including government oversight, manufacturer deficiency, company management, company procedure and documentation<em>,</em> people and activity management, technical failure, and environment. The functional block diagram and failure modes and effects analysis (FMEA) were applied to translate the technical failures of 12 environment control system failure cases into FMEA tabular statements. Several failure modes had been identified for environmental control system failure occurrences, e.g., sense line leakage, flawed sensor input, duct crack and leakage, broken part (pin and spring), seal degradation, contamination, tube rupture, mechanical joining defect, poor contact, and unanticipated failure instances for electronic centralized aircraft monitor (ECAM). Each failure mode can provide diagnostic information to identify and fix the environmental control system failure problem more effectively. In conclusion, this RRMF-based HMEP taxonomy provided a mental model to guide the data collection during an accident investigation and subsequently derive accident patterns as the core for Safety Management System (SMS) implementation.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"134 ","pages":"Article 104723"},"PeriodicalIF":3.4,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146115124","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}
