The advent of Industry 4.0 has transformed manufacturing by incorporating industrial robots to boost productivity and quality while cutting costs. Human-Robot Collaboration (HRC) is central to this shift, emphasizing seamless cooperation between humans and robots in shared workspaces. Evaluating the impact of such collaboration on human operators is crucial for efficiency, safety, and well-being. This systematic review explores methodologies for assessing human factors in HRC environments, spanning psychological, cognitive, and physical realms. Various evaluation methods have been identified, from subjective questionnaires to objective measurements. While subjective methods are the standard (especially questionnaires), there is a growing trend towards integrating physiological and physical measurements. The blend of subjective and objective methods offers a holistic understanding of human-robot interaction. This review adopts a more technical-oriented approach in the assessment of human factors in HRC. As a result, it consolidates existing methodologies and suggests avenues for further research, highlighting the significance of this assessment for enhancing productivity, safety, and well-being in industrial settings.
工业 4.0 的出现改变了制造业,它通过采用工业机器人来提高生产率和质量,同时降低成本。人机协作(HRC)是这一转变的核心,它强调人与机器人在共享工作空间中的无缝合作。评估这种协作对人类操作员的影响对于效率、安全和福祉至关重要。本系统综述探讨了评估人机协作环境中人为因素的方法,涵盖心理、认知和物理领域。从主观问卷到客观测量,各种评估方法均已确定。虽然主观方法是标准方法(尤其是问卷调查),但将生理和物理测量结合起来的趋势也在不断增长。主观方法和客观方法的结合有助于全面了解人机交互。本综述在评估人机交互中的人为因素时,采用了更注重技术的方法。因此,它整合了现有的方法,并提出了进一步研究的途径,强调了这一评估对提高工业环境中的生产率、安全性和幸福感的重要意义。

Wearable exoskeletons aim to balance physical work demands and individual capacity. This study assessed isometric pushing capacities in various directions using a chair-type exoskeleton (CEX) at different heights. Twenty participants of both genders underwent forward, backward, upward and sideways pushing. Using CEX increased posterior pushing by over 60%, decreased lateral pushing about 10%, but had no significant effect on anterior or superior pushing capacities. The weight distribution on the feet rose to 80% in posterior pushing and dropped to 20% in anterior pushing, while weight distribution between the feet and CEX, measured with two force plates, was about 5:5 in superior and lateral pushing. Despite increased posterior pushing, decrease in posterior stability with CEX should be considered. Workers and exoskeleton designers should be aware of this trade-off between increased pushing capacity and reduced posterior postural stability. With proper precautions to mitigate the risk of falling, introducing CEX can be especially beneficial for the workers needing to pull objects at lower levels.
可穿戴外骨骼旨在平衡体力劳动需求和个人能力。本研究使用不同高度的椅子型外骨骼(CEX)对不同方向的等距推举能力进行了评估。20 名男女参与者分别进行了向前、向后、向上和向侧的推举。使用 CEX 使后推力增加了 60%以上,侧推力减少了约 10%,但对前推力和上推力没有显著影响。在后推时,脚部的重量分布上升到 80%,而在前推时则下降到 20%,而在上推和侧推时,用两块力板测量的脚部和 CEX 之间的重量分布约为 5:5。尽管后推力增加,但应考虑到 CEX 后稳定性的下降。工人和外骨骼设计者应意识到推举能力增加与后部姿势稳定性降低之间的权衡。在采取适当的预防措施以降低跌倒风险的情况下,采用 CEX 对需要在较低位置拉动物体的工人尤其有益。

The U.S. Bureau of Labor Statistics projects that by the year 2029, the United States will lose a million jobs in the office and administrative support occupations because technology, automation, and artificial intelligence (AI) have the potential to substitute or replace the office and administrative functions performed by office workers. Despite the potential impact AI will have on office work and the important role office workers play in the American economy, we have limited knowledge of the state of the art research in office work at the intersection of emerging artificial intelligence technologies. In this study, we conducted a bibliometric analysis of the scholarly literature at the intersection of office work, office automation and artificial intelligence. We extracted literature sources from Compendex and Scopus databases and used VOSviewer for visualizing and quantifying our bibliometric analyses. Our findings from keywords analysis indicate that office automation, humans, human-computer interaction, and artificial intelligence occurred more frequently in the scholarly literature and had high link strengths. Keyword clusters from co-occurrence analysis indicate that intelligent buildings, robotics, and the internet of things are emerging topics in the office work domain. The two clusters related to ergonomics, worker characteristics, human performance, and safety indicate the types of human factors concerns that are more widely studied in office work settings. In summary, our findings on the state-of-the-art research in office work indicate that more studies have been conducted on smart buildings, robotics, and technology development for office work, compared to studies on office workers and their professional development.

Relevance to industry

This review on the state-of-the-art in research on office work is relevant in every industry that has the potential to undergo significant changes due to AI in the future.
美国劳工统计局预计,到 2029 年,美国将失去一百万个办公室和行政支持职业的工作岗位,因为技术、自动化和人工智能(AI)有可能替代或取代办公室工作人员所从事的办公室和行政职能。尽管人工智能将对办公室工作产生潜在影响,而且办公室工作人员在美国经济中发挥着重要作用,但我们对新兴人工智能技术交叉领域的办公室工作研究现状了解有限。在本研究中,我们对办公室工作、办公自动化和人工智能交叉领域的学术文献进行了文献计量分析。我们从 Compendex 和 Scopus 数据库中提取文献资料,并使用 VOSviewer 对文献计量分析进行可视化和量化。关键词分析结果表明,办公自动化、人类、人机交互和人工智能在学术文献中出现的频率较高,链接强度也较高。共现分析的关键词群表明,智能建筑、机器人和物联网是办公领域的新兴主题。与人体工程学、工人特征、人的表现和安全相关的两个群组表明,办公室工作环境中更广泛研究的是人为因素问题的类型。总之,我们对办公室工作领域最新研究的结果表明,与对办公室工作人员及其职业发展的研究相比,对智能建筑、机器人技术和办公室工作技术发展的研究较多。

The mastectomy bra (M-bra) serves as an essential rehabilitative product for individuals who have undergone breast cancer surgery. This study aimed to develop an ergonomic design method for M-bras that addresses both the physiological and psychological needs of post-mastectomy breast cancer patients. Over 270 M-bras with diverse design options were collected from online markets, and more than 100 post-mastectomy patients participated in an online survey to rank their preferences regarding eight M-bra components and 19 design options. An orthogonal experimental design was applied to reduce the vast array of design combinations to 20 M-bra test samples. The Pleasure-Arousal-Dominance (PAD) emotion model and the Self-Assessment Manikin (SAM) scale were then used to collect PAD scores from 40 patients evaluating these test samples. Extreme difference analysis was conducted to evaluate the significance of the M-bra components and identify combinations that generated the highest and lowest PAD levels. Based on the PAD scores, 11 samples were categorized as "delighted" or "relaxed" M-bras due to their positive emotional polarity. Linear regression analysis showed strong correlations between the design options and PAD scores, with R2 values of 0.962 for P, 0.819 for A, and 0.949 for D. A backpropagation neural network was developed to predict PAD values for various M-bra design options, achieving prediction errors of 8.06% for P, 6.15% for A, and 13.29% for D, demonstrating satisfactory performance given the subjective nature of the evaluations.
乳房切除术胸罩(M-bra)是乳腺癌术后患者必不可少的康复产品。本研究旨在开发一种符合人体工程学的胸罩设计方法,以满足乳腺癌切除术后患者的生理和心理需求。研究人员从网上市场收集了 270 多种不同设计方案的 M 型胸罩,并对 100 多名乳腺癌术后患者进行了在线调查,以了解他们对 8 种 M 型胸罩组件和 19 种设计方案的偏好程度。采用正交实验设计将大量设计组合减少到 20 个 M-bra 测试样本。然后使用愉悦-烦恼-主导(PAD)情绪模型和自评量表(SAM)收集了 40 名患者对这些测试样本的 PAD 评分。通过极差分析来评估 M-bra 成分的重要性,并确定产生最高和最低 PAD 水平的组合。根据 PAD 分数,11 个样本因其积极的情绪极性而被归类为 "愉悦 "或 "放松 "M-bra。线性回归分析表明,设计方案与 PAD 分数之间具有很强的相关性,P 的 R2 值为 0.962,A 为 0.819,D 为 0.949。我们开发了一个反向传播神经网络来预测各种 M-bra 设计方案的 PAD 值,P 的预测误差为 8.06%,A 的预测误差为 6.15%,D 的预测误差为 13.29%,考虑到评价的主观性,其表现令人满意。

One way to provide assistance in a dynamic lifting task is to pre-emptively move the exoskeleton based on a predicted reference trajectory. However, the level of aggressiveness in the prediction (i.e., how far ahead in time) and the exoskeleton's degree of adherence to the reference trajectory (stiffness) are not yet fully understood. This study investigated the effects of stiffness and pre-emptive offset parameters in an impedance-controlled robotic arm on muscle activation and perceived exertion of the user. Thirteen participants were instructed to lift a load equivalent to 15% of their maximal voluntary contracted force in collaboration with a robotic arm with 40°–135° of elbow flexion in 1.12 s. Three levels of stiffness (lower: 0.1 N m deg−1, medium: 0.2 N m deg−1, and higher: 0.31 N m deg−1) and two levels of pre-emptive offsets (shorter: 0.1 s and longer: 0.4 s) were investigated. We found that (1) during 0–0.5 s (acceleration stage) of elbow flexion, a higher stiffness level and a longer pre-emptive offset decreased muscle activity; (2) during 0.5–1 s (deceleration stage) of elbow flexion, medium and higher stiffness with a shorter pre-emptive offset decreased muscle activity; (3) the perceived exertion and assistance of participants were improved with a higher stiffness and a longer pre-emptive offset, whereas cooperation was rated higher at a shorter pre-emptive offset under higher stiffness. This study reveals that the optimal parameters for stiffness and pre-emptive offsets for predictive impedance controls are different for different stages of elbow flexion.
在动态提升任务中提供帮助的一种方法是根据预测的参考轨迹预先移动外骨骼。然而,预测的积极程度(即提前多长时间)和外骨骼对参考轨迹的依附程度(刚度)尚未完全明了。本研究调查了阻抗控制机械臂的刚度和预先偏移参数对肌肉激活和使用者感知用力的影响。13 名参与者被要求在 1.12 秒内与机械臂合作举起相当于其最大自主收缩力 15%的重物,肘关节屈曲 40°-135°。研究了三种刚度水平(较低:0.1 N m deg-1;中等:0.2 N m deg-1;较高:0.31 N m deg-1)和两种抢先偏移水平(较短:0.1 秒;较长:0.4 秒)。我们发现:(1) 在屈肘 0-0.5 秒(加速阶段)期间,较高的硬度水平和较长的抢先偏移降低了肌肉活动;(2) 在屈肘 0.5-1 秒(减速阶段)期间,中等和较高的硬度水平和较短的抢先偏移降低了肌肉活动;(3) 在较高的硬度水平和较长的抢先偏移下,参与者的感知用力和协助得到改善,而在较高的硬度水平和较短的抢先偏移下,参与者的合作性评分较高。这项研究揭示了预测阻抗控制的僵硬度和抢先偏移的最佳参数在肘关节屈曲的不同阶段是不同的。

The dynamics and frequency of change in today's workplaces force organizations to address the question of how to create optimal conditions for facilitating adaptation to change. Identifying critical factors that affect performance and well-being in change situations can help answer this question. Given the need for applied research in this area, the aim of this paper is to investigate whether the way of change implementation has an impact on performance and well-being. Additionally, retentivity and specific self-efficacy as individual factors are exploratorily investigated. In an experimental study, seventy-one participants learned and trained specific manufacturing steps in a simulated production environment. Subsequently, they had to adapt the trained task execution as some of the previously learned manufacturing steps were subject to change. The changes were implemented a) either in a stepwise manner or b) all at once. The executed manufacturing steps were recorded, enabling the calculation of task execution time and classification of adaptation errors. The results of Mann-Whitney-U-tests showed that the stepwise introduction of changes led to significantly faster task execution time than the change introduction all at once. Additionally, descriptive statistics indicated fewer adaptation errors but higher frustration. Our exploratory analysis showed a significant negative relationship between retentivity and task execution time, as well as between specific self-efficacy and frustration. Stepwise change introduction seems to be beneficial for adaptation, even though emotional responses and individual factors must be considered.
当今工作场所变化的动态性和频繁性迫使组织解决如何创造最佳条件以促进适应变化的问题。找出在变革情况下影响绩效和福利的关键因素有助于回答这个问题。鉴于该领域需要应用研究,本文旨在调查变革实施方式是否会对绩效和幸福感产生影响。此外,本文还对作为个体因素的缄默性和特定自我效能感进行了探索性研究。在一项实验研究中,71 名参与者在模拟生产环境中学习和训练了特定的生产步骤。随后,他们必须调整训练后的任务执行,因为之前学习的一些生产步骤可能会发生变化。这些变化可以 a) 逐步实施,也可以 b) 一次性实施。对执行的生产步骤进行记录,以便计算任务执行时间和对适应错误进行分类。Mann-Whitney-U 检验的结果表明,逐步引入变革的任务执行时间明显快于一次性引入变革的任务执行时间。此外,描述性统计表明,适应错误较少,但挫败感较高。我们的探索性分析表明,缄默性与任务执行时间之间以及特定自我效能感与挫败感之间存在显著的负相关。尽管必须考虑情绪反应和个人因素,但逐步引入变化似乎有利于适应。

Numerous flight accidents have been attributed to pilots' lack of situation awareness (SA), with distraction being a significant contributing factor. Therefore, identifying factors that may protect pilots' SA under distraction conditions and explore their mechanisms is crucial for promoting aviation safety. This study empirically investigates the effects of individual differences in working memory capacity (WMC) on pilots' SA when performing secondary tasks. The pilots were divided into two groups based on their performance on the WMC test and were asked to complete a simulated cockpit monitoring task under three secondary task difficulty conditions (no task, low-difficulty task, and high-difficulty task). SA in the simulated monitoring tasks was measured using the Situation Awareness Global Assessment Technique (SAGAT), and eye movement data were collected to analyze visual behaviors and attention allocation. Results showed that the difficulty of secondary task significantly impacted overall SA, the perceptual level of SA and dwell times; however, secondary task difficulty did not affect the perceptual level of SA in pilots with high WMC. These results suggest that WMC protects pilots' perceptual level SA when they perform secondary tasks. This study provides additional insights into the mechanisms of working memory in protecting SA and offers theoretical guidance for the design of complex technical systems and pilot psychological selection, which can help promote aviation safety.
许多飞行事故都归咎于飞行员缺乏态势感知(SA),而分心是一个重要的诱因。因此,确定在分心条件下保护飞行员态势感知的因素并探索其机制对于促进航空安全至关重要。本研究实证调查了工作记忆能力(WMC)的个体差异对飞行员执行次要任务时的 SA 的影响。根据飞行员在工作记忆容量测试中的表现将他们分为两组,并要求他们在三种次要任务难度条件下(无任务、低难度任务和高难度任务)完成模拟驾驶舱监控任务。在模拟监控任务中,使用情境意识总体评估技术(SAGAT)测量SA,并收集眼动数据来分析视觉行为和注意力分配。结果表明,次要任务的难度对总体SA、SA的感知水平和停留时间有显著影响;然而,次要任务的难度并不影响高WMC飞行员的SA感知水平。这些结果表明,当飞行员执行次要任务时,WMC 可以保护飞行员的感知水平 SA。本研究为工作记忆保护SA的机制提供了更多见解,为复杂技术系统的设计和飞行员心理选择提供了理论指导,有助于促进航空安全。

Work from home (WFH) may result in less physical activity and more sedentary behaviour among office employees. The consequence to body pain is unknown. The aim of this study was to assess longitudinal sedentary behaviour change and pain association among office workers who have been working from home. Baseline survey was administered to a cohort of office employees in January–February 2020. In March, all employees started to work from home in response to the COVID-19 pandemic. The additional surveys took place in April, June, and December 2020. The survey consisted of IPAQ, which included sitting time report, along with self-reported proportion of time spent standing during work, and body pain. Generalized estimating equations were used to analyse the trends in pain scores, and their associations to sitting time and standing frequency. The cohort consisted of 143 participants at baseline. Participants reported lower pain scores for neck (risk ratio = 0.90, CI = 0.82–0.99) and back (risk ratio = 0.85, CI = 0.75–0.96) in December, compared with pain scores at baseline. Neck pain among participants with more standing was lower than those with infrequent standing (risk ratio = 0.87, CI = 0.79–0.96). Weekly sitting time had no statistically significant effect on body pain scores. For WFH employees, more standing appears to have a significant protective effect on the neck. Being more sedentary during work does not have a clear detrimental effect on long-term musculoskeletal health.
在家办公(WFH)可能会导致办公室员工的体力活动减少,久坐行为增多。其对身体疼痛的影响尚不清楚。本研究的目的是评估在家工作的上班族的纵向久坐行为变化和疼痛关联。2020 年 1 月至 2 月,对一批办公室员工进行了基线调查。3 月,为应对 COVID-19 大流行,所有员工开始在家工作。附加调查分别于 2020 年 4 月、6 月和 12 月进行。调查内容包括 IPAQ,其中包括坐姿时间报告、工作期间站立时间的自我报告比例以及身体疼痛。采用广义估计方程分析疼痛评分的趋势及其与坐立时间和站立频率的关系。研究组共有 143 名基线参与者。与基线时的疼痛评分相比,参与者在 12 月份的颈部(风险比 = 0.90,CI = 0.82-0.99)和背部(风险比 = 0.85,CI = 0.75-0.96)疼痛评分较低。经常站立者的颈部疼痛低于不经常站立者(风险比 = 0.87,CI = 0.79-0.96)。每周坐着的时间对身体疼痛评分没有明显的统计学影响。对于全职工作的员工来说,多站似乎对颈部有明显的保护作用。工作期间久坐对长期肌肉骨骼健康没有明显的不利影响。

Household refrigerator concepts have evolved with changing applicational scenarios and requirements, providing users with support for healthy eating, personal care, and other activities in the kitchen and other areas of the home. However, current research on exploring user expectations and requirements for household refrigerators lacks considering the perspective of applicational scenarios and activity support. For this study, we invited 45 participants to explore immersive experience methods and conducted semi-structured interviews to investigate user requirements for future household refrigerators in different home areas and obtain dimensional details related to user needs, ultimately generating new insights into the demand for connected, intelligent, emotional, easy to use. Our findings are instructive for the design of future refrigerators in household scenarios and provide guidance and references for the design of other smart home appliances.

Work-related musculoskeletal disorders (WMSDs) seriously affect the health and well-being of oil and gas pipeline network operation and maintenance (O&M) employees. To assess the risk of WMSDs among employees in oil and gas pipeline O&M, this study constructs a systematic assessment methodology with typical job positions as the assessment object. This methodology includes identifying typical positions utilizing the Delphi method, determining the weights of risk indicators using the analytic network process, analyzing the impact consequences and possibilities of risk factors using the fuzzy comprehensive evaluation model, and evaluating the WMSD risk of each typical position combined with the risk assessment matrix. Moreover, the practicality and advantages of the methodology are verified through a case study. The results show that the method effectively assesses the WMSD risk of typical jobs in oil and gas pipeline operation and maintenance. Among the risk factors, movement and posture factors, as well as labor organization factors, had higher influence weights. Six typical jobs were identified, of which production process operators and mechanical maintenance engineers are high-risk jobs, while safety and environmental engineers have relatively low WMSD risk. Overall, this study provides an effective tool for assessing WMSD risk, thus promoting the well-being of O&M employees.
与工作相关的肌肉骨骼疾病(WMSDs)严重影响着油气管网运行维护(O&M)员工的健康和福利。为评估油气管网运行与维护(O&M)员工的 WMSDs 风险,本研究以典型工作岗位为评估对象,构建了一套系统的评估方法。该方法包括利用德尔菲法确定典型岗位,利用分析网络过程确定风险指标权重,利用模糊综合评价模型分析风险因素的影响后果和可能性,并结合风险评估矩阵对各典型岗位的WMSD风险进行评估。此外,还通过案例研究验证了该方法的实用性和优势。结果表明,该方法能有效评估油气管道运维典型岗位的 WMSD 风险。在风险因素中,动作和姿势因素以及劳动组织因素的影响权重较高。研究确定了六个典型工作岗位,其中生产工艺操作员和机械维修工程师属于高风险岗位,而安全工程师和环境工程师的 WMSD 风险相对较低。总之,这项研究为评估 WMSD 风险提供了一个有效的工具,从而促进了 O&M 员工的福祉。
