Camera control is crucial in telemanipulation, yet its effects on human operators remain underexplored. This study examined five camera viewpoint control models in a telemanipulated cube-stacking task involving 35 participants: (1) three fixed cameras; (2) two fixed cameras plus one dynamic camera with autonomous viewpoint control; (3) two fixed cameras plus one dynamic camera with manual viewpoint control; (4) a single dynamic camera with autonomous control; and (5) a single dynamic camera with manual control. We evaluated performance (cube-stacking success rate and completion time), cognitive load (eye-tracking measures of blink rate and pupillary activity, and perceived workload), visual attention (eye-tracking measures of fixation and saccade rates), and usability. Multiple-camera models improved task success but increased cognitive load (lower blink rates and higher pupillary activity) and saccade rates. Between multiple-camera models, autonomous-camera models showed lower saccade rates. Dynamic-camera models were rated more usable than fixed cameras. These findings reveal key trade-offs in camera control design and guide the creation of more efficient, operator-friendly telemanipulation systems.

相机控制在远程操作中是至关重要的，但它对人类操作员的影响仍未得到充分的研究。本研究考察了35名被试在远程操作立方体堆叠任务中的5种摄像机视点控制模型：(1)3台固定摄像机；(2) 2台固定摄像机+ 1台具有自主视点控制功能的动态摄像机；(3) 2台固定摄像机+ 1台手动视点控制动态摄像机；(4)具有自主控制功能的单个动态摄像机；(5)单个手动控制动态摄像机。我们评估了他们的表现（立方体堆叠成功率和完成时间）、认知负荷（眨眼率和瞳孔活动的眼动追踪测量，以及感知的工作量）、视觉注意力（注视和扫视率的眼动追踪测量）和可用性。多摄像头模型提高了任务的成功率，但增加了认知负荷（更低的眨眼频率和更高的瞳孔活动）和扫视率。在多摄像头模型中，自主摄像头模型的扫视率较低。动态相机模型被认为比固定相机更有用。这些发现揭示了相机控制设计中的关键权衡，并指导了更高效，操作员友好的远程操作系统的创建。

Objective

This scoping review summarises the amount and types of evidence available for workplace-based interventions that include the Stages of Change (SOC) framework in their design.

Methods

Seven electronic databases were searched for studies of workplace-based interventions that included SOC in their design. Studies were classified according to how SOC was incorporated into the intervention, the intervention target (individual or the organisation), which SOC measurement tools were used, and outcome measures.

Results

Thirty-six articles met the inclusion criteria. Four focused on organisational level ergonomics changes to work systems, the work environment, and/or work practices. The remaining three organisationally focused articles aimed to influence behaviours such as nutrition choices and smoking cessation, by modifying workplace factors such as the display of information and environmental changes.

The remaining 29 articles focused on modifying individual behaviours, primarily through the provision of information and/or coaching to participants. None of the included studies targeted managers or other workplace decision makers.

Conclusions

Four articles used SOC to implement ergonomics changes. Opportunities exist for further research evaluating how SOC could support organisational change, with particular regard to implementation of ergonomists’ advice and recommendations.

目的：本综述总结了基于工作场所的干预措施的数量和类型，这些干预措施包括其设计中的变化阶段（SOC）框架。方法检索7个电子数据库中包含SOC设计的基于工作场所的干预研究。研究根据SOC如何纳入干预、干预目标（个人或组织）、使用了哪些SOC测量工具以及结果测量进行分类。结果36篇文章符合纳入标准。其中四个侧重于组织层面的人机工程学对工作系统、工作环境和/或工作实践的改变。其余三篇以组织为重点的文章旨在通过改变信息显示和环境变化等工作场所因素，影响营养选择和戒烟等行为。其余29篇文章侧重于主要通过向参与者提供信息和/或指导来改变个人行为。纳入的研究都没有针对管理人员或其他职场决策者。结论4篇文章采用SOC实现了人机工程学的改变。有机会进一步研究评估SOC如何支持组织变革，特别是在实施人体工程学专家的建议和建议方面。

Aim

Characterise the physiological demands of a military dismounted assault task (DAT) simulation. Method: Fourteen men (mean ± SD: age 29 ± 9 years; body mass 79.9 ± 9.2 kg;

\dot{V}

O_2peak 51.9 ± 4.4 ml·kg⁻¹·min⁻¹; upright pull strength 177 ± 20 kg) performed a DAT (external load 24.3 kg) of 16 × 6 m bounds in 20 s cycles (5 s work, 15 s rest) followed by an 18 m leopard crawl. Performance and physiological demands (heart rate and indirect calorimetry via the Douglas bag technique) during the first and last 48 m of bounds and the leopard crawl were compared using a one-way repeated measures ANOVA. Performance was maintained across the first and last 48 m (bound speed 5.7 ± 0.9 and 5.8 ± 0.8 km·h⁻¹) despite substantial increases in oxygen consumption (first 48 m 25.4 ± 3.3 ml·kg⁻¹·min⁻¹; last 48 m 31.7 ± 3.5 ml·kg⁻¹·min⁻¹; leopard crawl 40.4 ± 6.4 ml·kg⁻¹·min⁻¹, p < 0.001, Ѡ2 = 0.64). Mean leopard crawl time was 26.1 ± 8.1 s at a speed of 2.7 ± 0.8 km·h⁻¹ and post-exercise blood lactate was 3.8 ± 1.4 mmol·L⁻¹. Increasing oxygen consumption with modest blood lactate responses suggests the demands of the DAT simulation are similar to intermittent high-intensity exercise and that aerobic fitness is an important determinant of performance.

目的：描述军事下马突击任务（DAT）模拟的生理需求。方法：14名男性（平均±SD：年龄29±9岁，体重79.9±9.2 kg， V˙o2峰51.9±4.4 ml·kg-1·min-1，直立拉力177±20 kg）在20 s循环（工作5 s，休息15 s）中进行16 × 6 m的data（外负荷24.3 kg），然后进行18 m的豹式爬行。使用单向重复测量方差分析比较了头48米和最后48米跳跃和豹子爬行期间的表现和生理需求（心率和通过道格拉斯袋技术进行的间接热量测量）。尽管耗氧量大幅增加（前48米25.4±3.3 ml·kg-1·min-1，后48米31.7±3.5 ml·kg-1·min-1，豹爬行40.4±6.4 ml·kg-1·min-1, p -1，运动后血乳酸为3.8±1.4 mmol·L-1），但在前48米和后48米期间（限速5.7±0.9和5.8±0.8 km·h-1），性能保持不变。增加氧气消耗和适度的血乳酸反应表明，DAT模拟的需求类似于间歇性高强度运动，有氧适能是表现的重要决定因素。

Introduction

This study aimed to compare fit, musculoskeletal pain and interference issues experienced by male and female Australian soldiers when wearing body armour, as well as quantify the extent to which anthropometric characteristics contribute to these issues.

Methods

77 male and 12 female Australian soldiers completed a questionnaire about their perception of body armour, including questions about fit, musculoskeletal pain, interference with other equipment and mobility restrictions.

Results

Females experienced disproportionate challenges with body armour fit, particularly excessive length and width, leading to greater musculoskeletal pain, equipment interference and mobility restrictions. Males also reported issues with body armour being too long and limiting mobility during occupational tasks. Front length was the strongest predictor of body armour-related issues, affecting mobility, comfort and acceptability more than chest breadth or circumference.

Conclusion

Body armour size and design modifications, particularly to system length, are necessary to improve fit and occupational performance.

本研究旨在比较澳大利亚男女士兵在穿着防弹衣时所经历的健康、肌肉骨骼疼痛和干扰问题，并量化人体测量特征对这些问题的影响程度。方法：77名男性和12名女性澳大利亚士兵完成了一份关于他们对防弹衣的看法的调查问卷，包括健康、肌肉骨骼疼痛、对其他设备的干扰和行动限制等问题。结果：女性在穿上防弹衣时遇到了不成比例的挑战，特别是长度和宽度过大，导致更大的肌肉骨骼疼痛、设备干扰和行动限制。男性还报告说，他们的防弹衣太长，在执行职业任务时限制了行动能力。前胸长度是最有力的防身衣相关问题的预测指标，它比胸宽或胸围更能影响移动性、舒适性和可接受性。结论：防弹衣的尺寸和设计的修改，特别是系统的长度，是必要的，以提高适合和职业表现。

The aim of this intervention study was to examine the effects of two different implementation approaches of a passive, upper-limb exoskeleton (MATE-XT®) on the acceptability of the exoskeleton by participants and participants’ health in a workplace health promotion setting.

Participants were assigned to one of two groups and underwent either an exoskeleton application training (AT, N = 9) or standardized briefing (SB, N = 9) over a period of 4 weeks. Outcomes of interest, i.e., acceptability of the exoskeleton and participants’ health, were assessed using the Technology Usage Inventory and the Short-Form 12 Health Survey before, immediately after, and approximately one year after the 4-week implementation period. Wearing time was tracked over the 4-week implementation period.

AT participants reported significantly higher usefulness and usability, greater curiosity, reduced skepticism, and had a higher wearing time in the last two weeks of the implementation. In addition, they perceived the exoskeleton as more useful, and reported higher physical health outcomes than SB participants. At one-year-follow-up, AT participants continued to perceive the exoskeleton as more valuable.

本干预研究的目的是检查在工作场所健康促进环境中，被动式上肢外骨骼（MATE-XT®）的两种不同实施方法对参与者外骨骼可接受性和参与者健康的影响。参与者被分配到两组中的一组，在4周的时间内接受外骨骼应用训练（AT, N = 9）或标准化简报（SB, N = 9）。在为期四周的实施期之前、之后和大约一年后，使用技术使用清单和简短的12健康调查来评估感兴趣的结果，即外骨骼的可接受性和参与者的健康。在为期四周的实施期内，追踪佩戴时间。AT参与者报告了显著更高的有用性和可用性，更大的好奇心，更少的怀疑，并且在实施的最后两周有更高的佩戴时间。此外，他们认为外骨骼更有用，并报告了比SB参与者更高的身体健康结果。在一年的随访中，At参与者仍然认为外骨骼更有价值。

Good health is vital for sustainable social and economic development and improving access to healthcare can help progress this goal. Telehealth is a digital technology that can strengthen health systems. One example is healthcare consultations using videoconferencing (VC) to connect patients and providers. Despite stakeholder benefits, there are challenges in integrating VC into routine practice which has led to failed VC services. This study, guided by the Systems Engineering Initiative for Patient Safety (SEIPS) 2.0 framework, investigated the impact of VC on healthcare work systems in Aotearoa New Zealand. Interviews with experts, healthcare providers and patients (n = 40) and observations at three healthcare sites showed that using VC has cross-level system impacts, including new ways of working, change, human connection and equity. The findings suggest human-centred design and consideration of system interactions could support sustained VC healthcare, with implications for future technology adoption and opportunities for ergonomics and human factors in system analysis and design.

良好的健康对可持续的社会和经济发展至关重要，改善获得卫生保健的机会有助于实现这一目标。远程医疗是一种可以加强卫生系统的数字技术。一个例子是使用视频会议（VC）连接患者和提供者的医疗保健咨询。尽管利益相关者受益，但将风险投资整合到日常实践中存在挑战，这导致了风险投资服务的失败。本研究在患者安全系统工程倡议（SEIPS） 2.0框架的指导下，调查了VC对新西兰Aotearoa医疗保健工作系统的影响。对专家、医疗保健提供者和患者的访谈（n = 40）以及在三个医疗保健站点的观察表明，使用风险投资具有跨层次的系统影响，包括新的工作方式、变革、人际关系和公平。研究结果表明，以人为中心的设计和系统交互的考虑可以支持持续的风险投资医疗保健，这对未来技术的采用以及系统分析和设计中人体工程学和人为因素的机会都有影响。

We investigated the effects of a shift schedule evaluation tool with ergonomics recommendations on employee wellbeing. The study sample was from the Finnish Public Sector study (n = 7002 employees). The shift planners' use of the shift schedule evaluation tool was linked to employees' self-reported wellbeing outcomes. Inverse probability weights, reflecting the likelihood of the evaluation tool's use by the shift planner, were calculated using multilevel mixed-effects logistic regression for each participant and logistic regression for each ward. Wards using the tool (intervention group) were compared to those not using it (control group) with a generalized linear model. No association was found between the tool's use and wellbeing at the ward level. In the individual level, lower psychological distress was found in the intervention group (Risk ratio 0.92, 95 % Confidence interval 0.85−0.99). More rigorous use of the tool may be necessary to achieve significant benefits for wellbeing.

我们调查了轮班时间表评估工具与人体工程学建议对员工福利的影响。研究样本来自芬兰公共部门研究（n = 7002名雇员）。轮班计划者对轮班时间表评估工具的使用与员工自我报告的健康结果有关。反概率权重反映了轮班计划者使用评估工具的可能性，对每个参与者和每个病房使用多级混合效应逻辑回归计算。使用该工具的病房（干预组）与未使用该工具的病房（对照组）采用广义线性模型进行比较。在病房层面上，没有发现工具的使用与幸福感之间的联系。在个体水平上，干预组的心理困扰程度较低（风险比0.92,95%可信区间0.85 ~ 0.99）。更严格地使用该工具可能是必要的，以实现对健康的重大好处。

Inverse probability weights, reflecting the likelihood of the evaluation tool's use by the shift planner, were calculated using multilevel mixed-effects logistic regression for each participant and logistic regression for each ward. Wards using the tool (intervention group) were compared to those not using it (control group) with a generalized linear model. No association was found between the tool's use and wellbeing at the ward level. In the individual level, lower psychological distress was found in the intervention group (Risk ratio 0.92, 95 % Confidence interval 0.85−0.99). More rigorous use of the tool may be necessary to achieve significant benefits for wellbeing.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"130 ","pages":"Article 104638"},"PeriodicalIF":3.4,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050073","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 investigation assessed the effect of gradient and duration on the gait variability exponent, DFA-α, in military personnel affixed with dual inertial measurement units performing a load carriage time-trial. Gait data (N = 14) were partitioned into 256 stride time segments by gradient (uphill, downhill) using a gait event algorithm. Detrended fluctuation analysis calculated DFA-α per segment, which was averaged across one-third durations (phases 1–3) per gradient. Two-way repeated measures ANOVA examined effects of gradient, duration, and interaction on DFA-α, with Bonferroni-adjusted post-hoc comparisons. There was a significant main effect of duration (phase 1: 0.593 ± 0.021; phase 2: 0.563 ± 0.031; phase 3: 0.493 ± 0.021; F = 3.833, p = 0.035, η_p² = 0.228), but not gradient (uphill: 0.486 ± 0.031; downhill: 0.614 ± 0.035; F = 4.252, p = 0.060, η_p² = 0.246), or interaction (F = 0.019, p = 0.981, η_p² = 0.001). Pairwise comparisons revealed significantly lower DFA-α during phase 3 than phase 1 (p = 0.016). Elapsed duration and uphill gradient, despite a large, but non-significant effect, may represent factors altering gait variability for injury risk.

本研究评估了坡度和持续时间对佩戴双惯性测量装置进行负重计时试验的军人步态变异性指数DFA-α的影响。采用步态事件算法将步态数据（N = 14）按梯度（上坡、下坡）划分为256个步幅时间段。去趋势波动分析计算每个段的DFA-α，每个梯度在三分之一持续时间（阶段1-3）内平均。双向重复测量方差分析检查梯度、持续时间和相互作用对DFA-α的影响，并采用bonferroni调整后的事后比较。持续时间（第一阶段：0.593±0.021；第二阶段：0.563±0.031；第三阶段：0.493±0.021;F = 3.833, p = 0.035, ηp2 = 0.228）是主要影响因素，而坡度（上坡：0.486±0.031；下坡：0.614±0.035;F = 4.252, p = 0.060, ηp2 = 0.246）和相互作用（F = 0.019, p = 0.981, ηp2 = 0.001）则不是主要影响因素。两两比较显示，第3期DFA-α显著低于第1期（p = 0.016）。持续时间和上坡坡度，尽管有很大但不显著的影响，可能代表了改变步态变异性的伤害风险因素。

Purpose

To share key learnings from the assessment of a COVID-19 vaccination system in Scotland using a Human Reliability Analysis (HRA) approach.

Method

Project data were collected in February 2021 in NHS Ayrshire and Arran (NHSAA) – the regional health authority - using document analysis (Service Delivery Manual, 2020), observations (2 site visits), and workshops (n = 8, with 26 participants). The Systematic Human Error Reduction and Prediction Approach (SHERPA) is a framework for human reliability analysis that can be used as part of a safety assessment or safety case to determine whether the system is ‘safe enough’ and provide recommendations to improve safety by mitigating error potential. In this paper it was used to assess the service delivery system and make recommendations.

Results

Many recovery mechanisms and risk control measures had already been implemented by NHSAA. Eighteen issues required additional risk control, grouped into three themes.

1.
Improve staff training and awareness, and the management of expectations.
2.
Improve equipment and information provision.
3.
Implement additional checks and contingencies.

Virtual reality (VR) training provides immersive, risk-free experiences that leverage multisensory integration to improve memory retention, presence and embodiment to strengthen engagement and attention, and situational learning to promote transfer of training to real-world contexts. Adding gamification through serious games (SG) further enhances engagement and active learning. This study validates a VR-SG safety training previously evaluated in Colombia, now applied to 74 professional roofers in Germany comparing ViStra (VR-SG) with LeStra (lecture-based with problem-based learning). Using Kirkpatrick's model, we assessed reaction, cognitive and attitudinal outcomes, self-reported behavior, and safety climate through validated questionnaires. Both programs improved cognitive and attitudinal outcomes, with no significant differences. No effects were found for behavior or safety climate. Thus, ViStra matched LeStra's effectiveness. Post hoc comparison with Colombian data suggests cultural factors influence some outcomes, highlighting the importance of adapting training strategies to cultural contexts for future safety training strategies in diverse work environments.

虚拟现实（VR）培训提供身临其境、无风险的体验，利用多感官整合来提高记忆保留、存在感和体现力，加强参与和注意力，以及情景学习，促进培训转移到现实环境中。通过严肃游戏（SG）加入游戏化，进一步提高参与度和主动学习。这项研究验证了之前在哥伦比亚评估的VR-SG安全培训，现在应用于德国的74名专业屋顶工人，比较了ViStra （VR-SG）和LeStra（基于讲座和基于问题的学习）。采用Kirkpatrick的模型，我们通过验证问卷评估反应、认知和态度结果、自我报告行为和安全气候。两种方案都改善了认知和态度结果，没有显著差异。没有发现对行为或安全气候的影响。因此，瑞致达达到了乐致达的效果。与哥伦比亚数据的事后比较表明，文化因素影响了一些结果，突出了使培训战略适应文化背景的重要性，以便在不同的工作环境中制定未来的安全培训战略。
