Videos of driving scenes were created and navigation-related AR-HUD imagery was added at different opacity levels. Twenty-seven participants watched these videos while their eye movements were tracked. Participants answered questions related to the opacity of the AR-HUD imagery and to their situation awareness. Results suggest that drivers are ambivalent about AR-HUD opacity, opacity affects how people look at and perceive the roadside environment, opacity levels of 20 % and 60 % both support situation awareness, and the effects of AR-HUD opacity are different for different types of AR-HUD imagery. Thus, AR-HUD opacity levels need to be further investigated to maximize driving safety.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"129 ","pages":"Article 104610"},"PeriodicalIF":3.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722435","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 study investigates the effects of correlated color temperature (CCT) and virtual daylight on human evaluations of virtual environments across two complementary experiments: one conducted in an uncontrolled real-world setting and the other in a controlled laboratory environment. Building on principles of human-centric lighting (HCL), we propose a framework for human-centric virtual lighting (HCVL) to optimize user experience in immersive digital spaces. In Experiment 1, participants evaluated 12 renderings of virtual exhibition stands and meeting spaces under varied lighting conditions, using Flynn et al.’s semantic differential scale. The real-world setting prioritized ecological validity, with participants using personal devices (with, for example, heterogeneous brightness and resolution) and representing diverse demographics (22 nationalities, ages 20–58). Experiment 2 replicated the design in a controlled laboratory condition, utilizing standardized monitors, and a homogeneous participant group (German undergraduate students, ages 18–26). Both experiments assessed perceptions of warmth, brightness, spaciousness, and preference, with statistical analyses comparing warm vs. cool CCT and daylight vs. room lighting effects. Key findings revealed large effects of CCT on perceived brightness and medium effects on stimulation and spaciousness, aligning with physical lighting research. Virtual daylight elicited robust preferences, rated as brighter, more private and aesthetically appealing, reflecting innate human biases toward daylight. Crucially, the laboratory results confirmed the real-world findings but with greater consistency, underscoring the impact of device variability and demographic diversity on the result from real-world setting. This study makes three primary contributions: (1) Empirical validation of HCVL principles, demonstrating that the effects of CCT and daylight transcend environmental modality (physical vs. virtual); (2) A methodological framework for balancing ecological validity and experimental control in virtual lighting research; (3) Practical insights for virtual space designers, emphasizing the integration of user expectations (e.g., “conceptual lighting”) and adaptive daylight simulations. These results bridge the gap between physical and virtual lighting research, offering actionable guidelines for creating immersive, well-being-oriented digital spaces. Future work should explore cultural and ambient moderators of HCVL to support inclusive virtual spaces design.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"129 ","pages":"Article 104601"},"PeriodicalIF":3.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713718","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}

Twenty-four participants (aged 18–35) performed the ANT six times in both conditions (5 min 35 per ANT). The proportion of blinks was significantly lower in the alternating condition than in the sitting-only condition. In both between-condition and within-condition analyses, the reaction times were significantly shorter when standing than when sitting. Humans may be more effective (i.e. a shorter reaction time) and have greater visual attention (i.e. less frequent proportion of blinking) in an alternating condition than in a sitting-only condition.

Hybrid teleworkers reported higher work stress and ICT demands than high-extent teleworkers. In both groups, high e-communication demands, work requiring concentration, and email challenges were associated with increased work stress. Conversely, job resources such as concentration-enabling workplaces, information sharing and collaboration reduced stress. Hybrid teleworkers experienced elevated stress from ICT difficulties, while high-extent teleworkers were more affected by relationship maintenance. Feeling appreciated was related to lower stress for high-extent teleworkers.

In the present study, 54 participants performed 10 iterations of the SART. After each SART, participants assessed both task-related thoughts and the lack of thoughts occurring during the SART. The lack of awareness of thoughts could be considered a form of mindlessness. Commission errors declined over iterations of the SART, indicating response inhibition improvement with task experience. The within-subjects (state) correlation between self-reported lack of thoughts (i.e., mindlessness) and errors in the SART was, however, near zero, indicating minimal, if any, relationship between self-reported mindlessness and performance. The importance of mindlessness or a lack of awareness of thought content on human performance in the traditional SART may be exaggerated.

A case study of barcode medication administration in a large hospital provides the empirical foundation for the guidelines. Data collection encompassed documentary analysis, shadowing of caregivers, interviews, focus groups, a survey for assessing risks of WAs, and a psychological safety survey. Results revealed 22 WAs, 43 contributing factors, nine potential desired outcomes and nine potential undesired outcomes. Tackling the contributing factors is crucial to reduce the frequency and risks associated with WAs. Five learning guidelines emerged, addressing: (<em>i</em>) prioritization of WAs based on their risk; (<em>ii</em>) emphasis on risk reduction rather than elimination; (<em>iii</em>) data-driven focus groups; (<em>iv</em>) limitations of WAs as a source of learning; and (<em>v</em>) use of language consistent with Safety-II; this guideline is accompanied by a new WA definition.

This study pursues a dual objective: firstly, to identify relevant for evaluating mental workload in an industrial maintenance environment, and secondly, to determine which of these indicators correlate with performance degradation. Ten participants performed five maintenance tasks of varying complexity on a helicopter, involving the removal, installation of components and a detailed inspection. Subjective measures (NASA-TLX), performance metrics (completion time), and cardiovascular data (heart rate, heart rate variability) were analyzed. We observed longer completion times and higher NASA-TLX scores for complex maintenance conditions. Regarding cardiovascular data, the results in the time domain of heart rate variability follow a similar trend compared to two other types of measurements.

The most frequently studied intervention was the use of dental loupes, followed by physical exercise programs. Musculoskeletal variables included pain reduction, posture, muscle function, physical stress, and surface body temperature, while performance outcomes involved work efficiency, procedure duration, tool positioning, ease and quality of dental procedures, and concentration levels. Musculoskeletal variables were assessed in all 51 studies, with 10 also evaluating performance outcomes. Positive effects of ergonomic interventions were reported in 38 studies, while 13 showed inconclusive results. No negative effects were observed.
