The use of exoskeletons in construction has the potential to enhance worker ergonomics and reduce musculoskeletal injuries by augmenting physical support during labor-intensive tasks. However, growing evidence suggests that exoskeletons, particularly active back-support exoskeletons (aBSEs), may unintentionally impair cognitive and perceptual performance due to biomechanical mismatches and elevated mental workload. This study investigates the effects of aBSE use on visual attention, situational awareness, and visual cognitive load during a construction-related task. An experimental study was conducted with sixteen participants using eye-tracking, electroencephalography (EEG), and the Situational Awareness Rating Technique (SART) to collect both objective and subjective data from participants performing the task with and without the exoskeleton. The results showed that aBSE use slightly reduces fixation-based metrics and significantly reduces saccade-based metrics across task-related areas of interest among the participants, indicating diminished visual attention. SART scores were notably lower among 60 % of the participants when using the exoskeleton, reflecting reduced situational awareness. Pupillometry and occipital EEG theta activity both significantly increased among the participants, indicating heightened visual cognitive load during aBSE use. These findings suggest that the cognitive demands associated with motor coordination and planning while using aBSEs may deplete attentional resources. This study makes several contributions: it applies and extends Kahneman's Capacity Model to explain how cognitive resource limitations manifest during exoskeleton-assisted work. The findings show that aBSEs can impair visual attention and situational awareness, underscoring the need for user-centered design and targeted training to help workers manage attention and safety risks during initial use.
在建筑中使用外骨骼有可能提高工人的工效学,并通过增加劳动密集型任务中的物理支持来减少肌肉骨骼损伤。然而,越来越多的证据表明,外骨骼,特别是主动背部支撑外骨骼(abse),可能会无意中损害认知和知觉表现,由于生物力学不匹配和精神负荷的增加。本研究探讨了在建构相关任务中使用aBSE对视觉注意、情境意识和视觉认知负荷的影响。一项实验研究对16名参与者进行了眼动追踪、脑电图(EEG)和情境感知评级技术(SART),以收集参与者在佩戴和不佩戴外骨骼时执行任务的客观和主观数据。结果表明,aBSE的使用略微降低了基于注视的指标,并显著降低了参与者在任务相关兴趣区域的基于眼跳的指标,表明视觉注意力下降。使用外骨骼时,60%的参与者的SART得分明显较低,反映出他们的态势感知能力下降。瞳孔测量和枕部脑电图θ活动在参与者中均显著增加,表明在使用aBSE期间视觉认知负荷增加。这些发现表明,在使用abse时,与运动协调和计划相关的认知需求可能会消耗注意力资源。这项研究有几个贡献:它应用并扩展了卡尼曼的能力模型,以解释在外骨骼辅助工作中认知资源的限制是如何显现的。研究结果表明,abse会损害视觉注意力和态势感知,强调需要以用户为中心的设计和有针对性的培训,以帮助工人在初始使用过程中管理注意力和安全风险。

In urban transportation settings, public transport signs act as common visual cues. Considering that color plays a critical role in sign detection and identification, it is necessary for researchers to gain a comprehensive understanding of color perception of signs. Existing research often depends on questionnaires and behavioral observation, lacking concrete evidence on cognitive processes. We employed Event-Related Potentials (ERPs) to determine the effect of diverse color public transport signs on passengers' attentional processing and emotional arousal, focusing on neural activity from varying brightness conditions. Findings indicated significant differences in P2 amplitude, showing perceptual responses to Sign colors in initial visual processing stages. Differences in LPP amplitude significantly influenced fine-grained processing in later stages of color perception. These ERPs differences provide valuable insight into subjects' attentional processing and emotional arousal. The presence of ERPs amplitudes in corresponding brain regions evidences the neural activity behind these responses. These insights reveal the actual effects of color brightness and help guide public transport providers to improve signage in promoting better passenger travel habits, and offer a solid measurement basis and reference for designing and displaying sign colors in practical applications.
在城市交通环境中,公共交通标志作为常见的视觉线索。考虑到颜色在符号检测和识别中起着至关重要的作用,研究人员有必要对符号的颜色感知有一个全面的认识。现有的研究往往依赖于问卷调查和行为观察,缺乏关于认知过程的具体证据。本研究利用事件相关电位(event -相关电位,ERPs)研究了不同颜色公交标志对乘客注意加工和情绪唤醒的影响,重点研究了不同亮度条件下的神经活动。结果表明,P2振幅存在显著差异,表明在视觉加工的初始阶段对符号颜色有知觉反应。LPP振幅的差异显著影响颜色感知后期的细粒加工。这些erp的差异为研究受试者的注意处理和情绪唤醒提供了有价值的见解。在相应脑区的erp振幅的存在证明了这些反应背后的神经活动。这些见解揭示了色彩亮度的实际效果,有助于指导公共交通供应商改进标识,促进更好的乘客出行习惯,并为实际应用中标识色彩的设计和展示提供坚实的测量依据和参考。

Effects of neck, shoulder, and back exoskeletons on muscle activity, kinematics, and perceived exertion during a simulated dental professional teeth cleaning task 在模拟牙科专业清洁任务中,颈部、肩部和背部外骨骼对肌肉活动、运动学和感知用力的影响
IF 3 2区 工程技术 Q2 ENGINEERING, INDUSTRIAL Pub Date : 2025-11-01 Epub Date: 2025-11-19 DOI: 10.1016/j.ergon.2025.103845

Previous research indicates that dental professionals are exposed to postures that are risk factors for musculoskeletal disorders and suffer from high incidence rates of musculoskeletal disorders in the shoulder, back, and neck. Exoskeletons are assistive devices with promising findings reported both in lab and worksite settings. The purpose of this study was to evaluate how shoulder, back, and neck exoskeletons impact muscle activity, joint angles, perceived exertion, and usability during a simulated teeth cleaning task commonly performed by dental professionals. Twenty-one participants completed simulated teeth cleaning without an exoskeleton and with a shoulder exoskeleton, back exoskeleton, and neck exoskeleton. Electromyography sensors measured muscle activity while a motion capture system measured kinematic data. Perceived exertion and usability questionnaires were completed. The shoulder exoskeleton reduced 50th and 95th percentile upper trapezius activity, splenius capitis activity, and neck flexion, but increased 50th and 95th percentile shoulder flexion and abduction. The back exoskeleton reduced perceived exertion but increased 50th and 95th percentile shoulder flexion. The neck exoskeleton reduced 50th and 95th percentile splenius capitis activity, shoulder flexion, and perceived exertion. The neck exoskeleton was rated first, back exoskeleton second, and shoulder exoskeleton third for usability. The results suggest that a neck exoskeleton may be the most promising option to potentially reduce the risk of musculoskeletal disorders for dental professionals. Further exoskeleton assessments with dental students and professionals are recommended.
先前的研究表明,牙科专业人员所接触的姿势是肌肉骨骼疾病的危险因素,并且在肩部,背部和颈部遭受肌肉骨骼疾病的高发病率。外骨骼是一种辅助设备,在实验室和工作场所都有很好的发现。本研究的目的是评估在牙科专业人员通常执行的模拟牙齿清洁任务中,肩部、背部和颈部外骨骼如何影响肌肉活动、关节角度、感知用力和可用性。21名参与者完成了模拟的牙齿清洁,没有外骨骼,有肩部外骨骼,背部外骨骼和颈部外骨骼。肌电传感器测量肌肉活动,而运动捕捉系统测量运动数据。完成感知用力和可用性问卷。肩部外骨骼降低了第50和第95百分位的上斜方肌活动、头脾活动和颈部屈曲,但增加了第50和第95百分位的肩部屈曲和外展。背部外骨骼减少了感知的劳累,但增加了第50和第95百分位的肩部屈曲。颈部外骨骼减少了第50和95个百分位的头脾活动、肩部屈曲和感觉劳累。颈部外骨骼的可用性排名第一,背部外骨骼排名第二,肩部外骨骼排名第三。研究结果表明,对于牙科专业人员来说,颈部外骨骼可能是最有希望降低肌肉骨骼疾病风险的选择。建议与牙科学生和专业人员进行进一步的外骨骼评估。

Non-visual effects of correlated color temperature and time-of-day on cognitive workload and autonomic regulation in confined spaces 封闭空间中相关色温和时间对认知负荷和自主调节的非视觉影响

Artificial lighting is essential in confined environments where natural daylight is absent, serving as both the primary visual source and a key modulator of non-visual processes related to circadian regulation. This study investigated the combined effects of correlated color temperature (CCT) and time-of-day on cognitive workload and autonomic responses in a daylight-free confined cabin. Fifteen healthy young adults (10 males, 5 females; aged 18–27 years; BMI 18.5–25.4 kg/m2) were exposed to three CCT conditions (across three time periods 09:00–12:00, 14:00–17:00, 19:00–22:00). During each session, participants performed N-back tasks while electroencephalography (EEG), heart rate variability (HRV), behavioral outcomes, and subjective ratings (KSS, SAS, WCS) were collected. Results showed that 6500K lighting was associated with faster response speed, lower anxiety and workload ratings, and increased β-wave activity, particularly in the afternoon. Conversely, 2700K lighting was associated with parasympathetic-leaning HRV patterns, supporting relaxation. Time-of-day effects were also observed, with higher sleepiness and altered cortical activation in the afternoon. Because circadian phase biomarkers were not directly measured, we refrain from causal claims of entrainment; instead, the multimodal evidence indicates that CCT and time-of-day jointly modulate cognitive and autonomic responses. These findings provide practical implications for ergonomic and health-supportive lighting design in confined cabins.
在没有自然光的密闭环境中,人工照明是必不可少的,它既是主要的视觉来源,也是与昼夜节律调节相关的非视觉过程的关键调制器。本研究探讨了在无日光密闭舱内,相关色温(CCT)和时间对认知负荷和自主反应的综合影响。15名健康年轻人(10名男性,5名女性,年龄18-27岁,BMI 18.5-25.4 kg/m2)暴露于三种CCT条件下(三个时间段09:00-12:00,14:00-17:00,19:00-22:00)。在每次会议中,参与者执行N-back任务,同时收集脑电图(EEG),心率变异性(HRV),行为结果和主观评分(KSS, SAS, WCS)。结果表明,6500K照明与更快的反应速度、更低的焦虑和工作量评级以及增加的β波活动有关,尤其是在下午。相反,2700K照明与副交感倾向的HRV模式有关,支持放松。一天中的时间效应也被观察到,下午更困,大脑皮层激活改变。由于没有直接测量昼夜节律阶段生物标志物,我们避免了夹带的因果主张;相反,多模态证据表明,CCT和时间共同调节认知和自主反应。这些发现为密闭舱室的人体工程学和健康支持照明设计提供了实际意义。

Vacuuming is a high physical demand task for building cleaners. The effects of backpack vacuum carrying position along the spine and carpet vacuuming techniques on the physical workload were examined in this laboratory study. Twenty-two professional and novice cleaners volunteered to vacuum in six different scenarios. The scenarios included three backpack carrying positions on the back, combined with two vacuuming techniques, front-to-back (FB) and the manufacturer-recommended side-to-side (SS). Muscle activity in the trapezius and infraspinatus muscles of the dominant shoulder, percent heart rate reserve (%HRR), and self-reported bodily discomfort on the shoulder and lower back were reported to evaluate the physical workloads. Peak trapezius muscle loading was significantly higher with the SS technique among professional cleaners (p < 0.05). Conversely, the peak infraspinatus muscle loading was significantly lower with the SS technique (p < 0.05) for the same group. There was a statistically significant interaction effect of vacuuming techniques and backpack positions on %HRR. The SS technique caused less discomfort in the dominant shoulder among novice cleaners compared to the FB technique, but not for professional cleaners. The professional cleaners activated the right trapezius muscle with the SS technique as they did with the FB technique, instead of twisting their torso, as intended by the latter. Therefore, the SS technique could not lower the discomfort on the dominant shoulder and lower back among professional cleaners. On the other hand, novice users benefited from adopting the SS technique.
吸尘对建筑清洁工来说是一项体力要求很高的工作。在这个实验室研究中,研究了沿脊柱的背包真空携带位置和地毯真空技术对身体负荷的影响。22名专业和新手清洁工自愿在6个不同的场景中吸尘。这些场景包括背部的三个背包携带位置,结合两种真空技术,前对后(FB)和制造商推荐的侧对侧(SS)。报告了主肩斜方肌和冈下肌的肌肉活动、心率储备百分比(%HRR)和肩部和下背部自我报告的身体不适来评估体力负荷。专业清洁人员使用SS技术时,斜方肌负荷峰值显著增高(p < 0.05)。相反,在同一组中,SS技术的冈下肌负荷峰值显著降低(p < 0.05)。吸尘技术和背包位置对%HRR有显著的交互作用。与FB技术相比,SS技术在新手清洁人员中引起的主肩不适较少,但对专业清洁人员没有。专业清洁工用SS技术激活了右侧斜方肌,就像他们用FB技术一样,而不是像后者那样扭曲他们的躯干。因此,SS技术不能降低专业清洁人员的主肩和下背部不适。另一方面,新手用户从采用SS技术中获益。

Review of upper-limb occupational exoskeletons: From technology to assessment 上肢职业外骨骼研究综述:从技术到评估
IF 3 2区 工程技术 Q2 ENGINEERING, INDUSTRIAL Pub Date : 2025-11-01 Epub Date: 2025-10-08 DOI: 10.1016/j.ergon.2025.103815

Occupational exoskeletons are emerging as a promising solution to reduce work-related musculoskeletal disorders (MSDs) across various industries. Upper-limb exoskeletons are particularly relevant, given the high prevalence of MSDs associated with repetitive arm motions and overhead tasks. However, evaluating the effectiveness of these devices requires careful analysis of the specific technologies and kinematic designs they incorporate to ensure their safe and effective integration. This paper presents a detailed technological review and analysis of the existing literature, focusing on the diversity of technologies and the need for more comprehensive studies addressing challenges in both laboratory and real-world settings. This study particularly highlights the necessity of assessments that account for the unique characteristics of different exoskeleton technologies, rather than generalizing across them. It also emphasize the need to examine not only reductions in muscle activity but also the potential for overlooked side effects, long-term impacts, and adaptations across different task types. These factors are crucial, as upper-limb exoskeletons are planned to be deployed for prolonged use in complex industrial environments.
职业外骨骼正在成为一个有前途的解决方案,以减少与工作有关的肌肉骨骼疾病(MSDs)在各个行业。考虑到与重复性手臂运动和头顶任务相关的msd的高患病率,上肢外骨骼尤其相关。然而,评估这些装置的有效性需要仔细分析它们所包含的具体技术和运动学设计,以确保其安全有效地集成。本文对现有文献进行了详细的技术回顾和分析,重点关注技术的多样性以及在实验室和现实世界环境中应对挑战的更全面研究的必要性。这项研究特别强调了对不同外骨骼技术的独特特征进行评估的必要性,而不是对它们进行概括。它还强调,不仅需要检查肌肉活动的减少,还需要检查潜在的被忽视的副作用、长期影响以及不同任务类型的适应性。这些因素是至关重要的,因为上肢外骨骼计划在复杂的工业环境中长期使用。

These factors are crucial, as upper-limb exoskeletons are planned to be deployed for prolonged use in complex industrial environments.</div></div>","PeriodicalId":50317,"journal":{"name":"International Journal of Industrial Ergonomics","volume":"110 ","pages":"Article 103815"},"PeriodicalIF":3.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145268647","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}

Artificial intelligence (AI), as an advanced technological innovation, possesses considerable promise for improving energy efficiency and reducing emissions in industrial environments. Although AI plays a crucial role in industrial decarbonization, research reveals that many AI-dependent carbon reduction prospects remain untapped. This study examines the innovative correlation between the presentation styles of industrial AI recommendations and the trust that carbon management technicians have in AI from an ergonomic standpoint. This study combines the Stimulus-Organism-Response theory with the Elaboration Likelihood Model. The findings from three experiments reveal that precise and informative styles of AI recommendations enhance trust among technicians. Furthermore, we present mediating evidence with advanced eye-tracking devices, illustrating that cognitive effort strengthens the positive effect of precise abatement recommendations on trust toward AI (Study 2). Further research indicates that the positive effect of precise or informative AI-generated abatement recommendations on trust is amplified when technicians experience more positive emotions (Study 3). Overall, this study identifies distinct mechanisms through which the presentation styles of industrial AI recommendations can affect technicians' trust. These findings hold practical significance for developers of industrial AI systems and carbon management technicians who strategically utilize AI-generated information.
人工智能(AI)作为一项先进的技术创新,在提高工业环境的能源效率和减少排放方面具有相当大的前景。尽管人工智能在工业脱碳中发挥着至关重要的作用,但研究表明,许多依赖人工智能的碳减排前景仍未开发。本研究从人体工程学的角度考察了工业人工智能建议的呈现风格与碳管理技术人员对人工智能的信任之间的创新相关性。本研究将刺激-生物-反应理论与精细可能性模型相结合。三个实验的结果表明,精确和信息丰富的人工智能推荐风格增强了技术人员之间的信任。此外,我们提出了先进的眼动追踪设备的中介证据,说明认知努力加强了精确的消减建议对AI信任的积极影响(研究2)。进一步的研究表明,当技术人员体验到更多的积极情绪时,人工智能产生的精确或信息丰富的缓解建议对信任的积极影响会被放大(研究3)。总体而言,本研究确定了不同的机制,通过这些机制,工业人工智能推荐的呈现风格可以影响技术人员的信任。这些发现对于工业人工智能系统的开发人员和战略性地利用人工智能生成的信息的碳管理技术人员具有实际意义。

Rope skipping is now a popular and effective weight loss method enjoyed by many individuals. However, due to the limited support from muscles and bones in the female breasts, breast tissue moves relative to the chest wall during physical activities, leading to discomfort, especially in women with larger breasts. This study aims to explore the movement range of larger breasts in relation to the chest with a focus on analysing the jumping-induced boundary position of the breast and its biomechanical characteristics during rope skipping exercises. By employing the 4D dynamic body scanning technology, the study recorded the breast movement of women with larger breasts during cordless rope skipping exercises under the braless condition, to identify the moment and location of the maximum movement boundary of the breast in the vertical direction. The results indicated that within 0.2 ± 0.05s of the rope skipping cycle, the upward movement of the breasts would reach their maximum, followed by downward sliding. Furthermore, it was also found that the breasts not only moved vertically during the rope skipping cycle, but also slide outward along with the curvature of the thorax. By analysing the motion range of the upper boundary across all participants, it was found that these boundary points typically located 4–7 cm above the line connecting the anterior axillary points. This study provides a new method and reference for defining the biomechanical boundaries of larger breasts, offering a valuable foundation for sports bra design, especially the design for upper breast region.
跳绳现在是一种流行和有效的减肥方法,许多人都喜欢。然而,由于女性乳房中肌肉和骨骼的支撑有限,在体育活动中,乳房组织相对于胸壁移动,导致不适,特别是对于乳房较大的女性。本研究旨在探讨大乳房相对于胸部的运动范围,重点分析跳绳运动中乳房的跳跃诱发边界位置及其生物力学特征。本研究采用4D动态身体扫描技术,记录胸大女性在不戴胸罩的情况下进行无绳跳绳运动时的乳房运动,识别乳房在垂直方向上最大运动边界的时刻和位置。结果表明,在跳绳周期的0.2±0.05s内,胸部向上运动达到最大值,其次是向下滑动。此外,还发现在跳绳周期中,乳房不仅垂直移动,而且随着胸部的弯曲向外滑动。通过分析所有参与者上边界的运动范围,发现这些边界点通常位于连接前腋窝点的线上方4-7厘米。本研究为确定大乳房的生物力学边界提供了新的方法和参考,为运动文胸的设计,特别是上乳房区域的设计提供了有价值的依据。

This study aims to identify conditions that promote work sustainability after technological transition processess in an industrial context, and understand the possibilities of operators' involvement in these. Two use-cases in a manufacturing company were part of the study with the project development team, HR, team leaders and the workers who will interact with the new technologies. Following a work activity-oriented approach, the results demonstrated that there is still progress to be made to move towards a human-centered approach (e.g., consideration for workers and their work activity; organizational support to skills development). However, conditions that favor a renewed work activity within the technological transitions aligned with the I5.0 paradigm were also found and taken into account into an evidence-based framework of guidelines for sustainable work conditions. This framework considers an organizational, collective, and individual level of guidelines aimed to support companies’ stakeholders in the design and implementation of human-centered technological transitions. This study contributes to fostering the I5.0 transition, seeking sustainable conditions for workers and their work possibilities.
本研究旨在确定在工业背景下技术转型过程后促进工作可持续性的条件,并了解运营商参与其中的可能性。制造公司的两个用例是项目开发团队、人力资源、团队领导和将与新技术交互的工人的研究的一部分。在以工作活动为导向的方法之后,结果表明,在朝向以人为中心的方法(例如,考虑工人及其工作活动;组织对技能发展的支持)方面仍有待取得进展。然而,在符合I5.0范式的技术转型中,有利于重新开展工作活动的条件也被发现,并被考虑到可持续工作条件的循证指导框架中。该框架考虑了组织、集体和个人层面的指导方针,旨在支持公司的利益相关者设计和实现以人为中心的技术转型。这项研究有助于促进5.0的过渡,为工人和他们的工作可能性寻求可持续的条件。

AR vs. physical displays: Pharmacists’ performance in identifying look-alike drug names AR与物理显示:药剂师在识别相似药物名称方面的表现
IF 3 2区 工程技术 Q2 ENGINEERING, INDUSTRIAL Pub Date : 2025-09-01 Epub Date: 2025-08-03 DOI: 10.1016/j.ergon.2025.103794

Similar drug name confusion poses a significant risk in pharmacy practice, leading to medication errors with serious consequences. This study investigates pharmacists’ performance in recognizing look-alike drug names using an augmented reality (AR) virtual display versus a physical liquid crystal display (LCD) monitor. The influence of prior AR experience on performance was also examined. Twenty licensed pharmacists participated, performing recognition tasks on similar drug name pairs, with performance measured by accuracy rate, response time, fixation duration, and total fixation count. Results indicate that participants achieved an accuracy rate exceeding 96 % across all conditions, with overall accuracy slightly higher in the physical monitor environment. The AR display enabled task completion with significantly fewer total fixations compared to the physical monitor (p < 0.05). Additionally, participants with prior AR experience exhibited faster response times and shorter fixation durations in the AR environment. There were interactions between environment and prior AR experience for response time and fixation duration, suggesting that performance across environments varied depending on user familiarity. While physical and AR displays each present unique advantages and limitations, these findings underscore the importance of user familiarity in adapting to emerging technologies in pharmacy practice.
类似的药品名称混淆在药学实践中构成了重大风险,导致用药错误和严重后果。本研究调查了药剂师在使用增强现实(AR)虚拟显示器和物理液晶显示器(LCD)显示器识别相似药物名称方面的表现。我们还研究了先前AR经验对表现的影响。20名执业药师对相似的药品名称对进行识别,以正确率、反应时间、注视时间和总注视次数为衡量指标。结果表明,参与者在所有条件下的准确率都超过96%,在物理监测环境下的总体准确率略高。与物理显示器相比,AR显示器能够以更少的总注视完成任务(p <;0.05)。此外,具有AR经验的参与者在AR环境中表现出更快的反应时间和更短的注视时间。在响应时间和注视时间方面,环境和先前AR体验之间存在交互作用,这表明不同环境下的表现取决于用户的熟悉程度。虽然物理和增强现实各自显示出独特的优势和局限性,但这些发现强调了用户熟悉度在药房实践中适应新兴技术的重要性。
