In the era of Industry 4.0, the study of Human–Robot Collaboration (HRC) in advancing modern manufacturing and automation is paramount. An operator approaching a collaborative robot (cobot) may have feelings of distrust, and experience discomfort and stress, especially during the early stages of training. Human factors cannot be neglected: for efficient implementation, the complex psycho-physiological state and responses of the operator must be taken into consideration. In this study, volunteers were asked to carry out a set of cobot programming tasks, while several physiological signals, such as electroencephalogram (EEG), electrocardiogram (ECG), Galvanic skin response (GSR), and facial expressions were recorded. In addition, a subjective questionnaire (NASA-TLX) was administered at the end, to assess if the derived physiological parameters are related to the subjective perception of stress. Parameters exhibiting a higher degree of alignment with subjective perception are mean Theta (76.67%), Alpha (70.53%) and Beta (67.65%) power extracted from EEG, recovery time (72.86%) and rise time (71.43%) extracted from GSR and heart rate variability (HRV) metrics PNN25 (71.58%), SDNN (70.53%), PNN50 (68.95%) and RMSSD (66.84%). Parameters extracted from raw RR Intervals appear to be more variable and less accurate (42.11%) so as recorded emotions (51.43%).
在工业 4.0 时代,研究人机协作(HRC)对推进现代制造和自动化至关重要。操作员在接触协作机器人(cobot)时可能会产生不信任感,并体验到不适和压力,尤其是在培训的早期阶段。人为因素不容忽视:为了有效实施,必须考虑到操作员复杂的心理生理状态和反应。在这项研究中,志愿者被要求执行一组 cobot 编程任务,同时记录一些生理信号,如脑电图(EEG)、心电图(ECG)、皮肤伽伐尼反应(GSR)和面部表情。此外,最后还进行了主观问卷调查(NASA-TLX),以评估得出的生理参数是否与压力的主观感受相关。从脑电图中提取的平均 Theta(76.67%)、Alpha(70.53%)和 Beta(67.65%)功率,从 GSR 中提取的恢复时间(72.86%)和上升时间(71.43%),以及心率变异性(HRV)指标 PNN25(71.58%)、SDNN(70.53%)、PNN50(68.95%)和 RMSSD(66.84%),这些参数与主观感受的吻合程度较高。从原始 RR 间隔提取的参数似乎变化较大,准确度较低(42.11%),而记录的情绪参数准确度较高(51.43%)。

In this study, a conditional automated driving scenario is simulated using virtual reality (VR) technology to explore whether office works presented through augmented reality (AR) affect task and takeover performance, and the neural mechanism was revealed. Sixty-four participants were recruited and their electroencephalography (EEG) was used to measure the brain activities. The results indicated that non-driving-related tasks (NDRTs) requiring higher internal attention focus resulted in poorer task and takeover performance. The alpha power decline magnitude in the parietotemporal (PT) was positively correlated with the takeover time; and the greater the alpha power decline in the right centroparietal (CP) hemisphere, the worse is the participants’ memory quality for NDRTs. The ventral attention network (VAN) and right parietal cortex, which are active during working memory, are more likely to explain these findings. The results can provide suggestions for the design of AR-ADS and help improve the safety in L3 driving automation systems.
本研究利用虚拟现实(VR)技术模拟有条件自动驾驶场景,探讨通过增强现实(AR)呈现的办公作品是否会影响任务和接管性能,并揭示其神经机制。研究共招募了 64 名参与者,并使用脑电图(EEG)测量他们的大脑活动。结果表明,与驾驶无关的任务(NDRTs)需要更高的内部注意力集中,这导致任务和接管表现较差。顶颞叶(PT)的α功率下降幅度与接管时间呈正相关;右顶叶半球(CP)的α功率下降幅度越大,参与者对NDRT的记忆质量越差。在工作记忆期间活跃的腹侧注意网络(VAN)和右顶叶皮层更有可能解释这些发现。研究结果可为AR-ADS的设计提供建议,并有助于提高L3自动驾驶系统的安全性。

This study assessed the effect of a small-torque generating passive back-support exoskeleton during a low demanding occupational task, namely a repetitive lifting/lowering of an empty crate between the knee and shoulder heights. A comprehensive set of outcomes was considered, ranging from the measured trunk muscle activation and trunk movement to the estimated muscle group forces/coordination, spine loading and spine stability, using a dynamic subject-specific EMG-assisted musculoskeletal model. The exoskeleton decreased back muscle activation and corresponding muscle forces in the lowering phase and reduced spinal loading at larger trunk flexion angles (decreased peak compression and shear forces by ∼ 15%). However, the effect sizes were small (ηG2 < .06), questioning the usefulness of this type of exoskeleton, even for light tasks. On the other hand, the unique results of the present study showed that coordination between the main muscle groups as well as spinal stability remained unchanged with low effect sizes, suggesting that the use of this exoskeleton is safe.

An accident on a passenger ferry may lead to evacuation using lifeboats or liferafts, a process that can be both complex and hazardous. This paper investigates the level of safety for passengers during evacuation based on field study and interview data. In the analysis, the eight goals of Universal Design (UD) were tailored and used to explore what ship and interior characteristics influence evacuation performance and the demands placed on the crew and passengers, and whether all passengers have equal chances of completing evacuation safely.
Results suggest that while a ship may fulfil regulation, completing an evacuation may pose challenges for passengers with varying abilities, for example, when attempting to perceive emergency information or move through the ship. In addition, it was found that an evacuation may present the crew with challenges and difficult trade-offs that are not always accounted for in the ship's design, equipment and safety organization. It is concluded that the use of a UD approach in ship design, based on a truthful representation of passenger demographics, could enhance passenger safety and provide for evacuation on equal terms.
客轮上的事故可能导致使用救生艇或救生筏进行疏散,这一过程可能既复杂又危险。本文基于实地研究和访谈数据,对乘客在疏散过程中的安全水平进行了调查。结果表明,虽然船舶可能符合规定,但完成疏散可能会给不同能力的乘客带来挑战,例如,在试图感知紧急信息或在船上移动时。此外,研究还发现,疏散可能会给船员带来挑战和困难,而这些挑战和困难并不总是在船舶设计、设备和安全组织中得到考虑。研究得出结论,在船舶设计中使用基于乘客人口统计数据的 UD 方法,可以提高乘客的安全性,并提供平等的疏散条件。

The autonomous, digital, and electric transformation of passenger vehicles is projected to elevate the incidence of motion sickness among occupants. This study investigates the effectiveness of an “anti-motion sickness” system that features dynamic light stimuli to support visual perception of longitudinal motion, combined with relaxing music, perfume and ventilation pulses to enhance user wellbeing. In an experimental design aimed at replicating a realistic passenger drive, fifty-three subjects were tested as front passengers engaged in a gaming activity. Subjective motion sickness ratings were collected throughout the drive, and the development of symptoms was monitored through in-ear physiological measurements, including RR-intervals, core temperature, and oxygen saturation. Post hoc analyses indicated non-significant improvement in subjective assessments of motion sickness. Similarly, physiological measurements did not demonstrate any significant difference across conditions. The tested system was however more effective in mitigating car sickness for low susceptible than for mid-to-high susceptible individuals.

The COVID-19 pandemic demonstrated the need for respiratory protection against airborne pathogens. Respirator options for children are limited, and existing designs do not consider differences in facial shape or size. We created a dataset of children's facial images from three cohorts, then used geometric morphometric analyses of dense and sparse facial landmark representations to quantify age, sex and ancestry-related variation in shape. We found facial shape and size in children vary significantly with age from ages 2 to 18, particularly in dimensions relevant to respirator design. Sex differences are small throughout most of the age range of our sample. Ancestry is associated with significant facial shape variation in dimensions that may affect respirator fit. We offer guidance on how to our results can be used for the appropriate design of devices such as respirators for pediatric populations. We also highlight the need to consider ancestry-related variation in facial morphology to promote equitable, inclusive products.
COVID-19 大流行表明,需要针对空气传播的病原体提供呼吸保护。适用于儿童的呼吸器非常有限,而且现有的设计没有考虑到面部形状或大小的差异。我们创建了一个来自三个队列的儿童面部图像数据集,然后使用密集和稀疏面部地标表示的几何形态计量分析来量化与年龄、性别和祖先有关的形状差异。我们发现,从 2 岁到 18 岁,儿童的面部形状和大小随着年龄的增长而显著变化,尤其是在与呼吸器设计相关的维度上。在样本的大部分年龄段中,性别差异很小。血统与脸型的显著差异有关,而这些差异可能会影响呼吸器的适配性。我们就如何利用我们的研究结果为儿科人群设计合适的呼吸器等设备提供了指导。我们还强调有必要考虑与祖先有关的面部形态差异,以推广公平、包容的产品。

The purpose of this study was to gather ergonomists’ perspectives and experiences, describing current challenges and contextual considerations in risk assessment, exploring how ergonomists are currently integrating the multiple domains of ergonomics for MSD and/or psychological health and safety and highlighting key considerations in the design and format of future tools.
In-depth, semi-structured interviews were conducted with twenty Canadian ergonomists to explore risk assessment tool use, favoured characteristics and format of tools, commonly addressed risk factors in their practice, and tools relating to both MSD prevention and psychological health and safety. The range of practitioner years of experience highlighted differing needs and approaches to the use and formatting of risk assessment tools. Practitioners reported using quantitative outcomes (levels of risk, values) from traditional physical tools complemented by a general observation of psychosocial or organizational factors. Though many respondents had not yet encountered the need for psychological injury assessment in their sectors it was identified as a quickly emerging area citing a need for valid and reliable tools. Practitioners noted a lack of available tools that integrated cognitive and psychosocial items presenting a future challenge for integrated tools that covered multiple ergonomic domains. Along with recommendations for future tool development, the authors reflect on the process of qualitative inquiry as an essential step in the risk assessment process. Future studies will be needed to develop and evaluate measurement properties of integrating psychosocial factors and their respective tools in traditional MSD assessment.
这项研究的目的是收集人体工程学专家的观点和经验,描述风险评估当前面临的挑战和背景因素,探索人体工程学专家目前如何将人体工程学的多个领域整合到MSD和/或心理健康与安全中,并强调未来工具设计和格式中的主要考虑因素。我们对二十位加拿大人体工程学专家进行了深入的半结构式访谈,以探讨风险评估工具的使用、工具的首选特征和格式、实践中常见的风险因素,以及与MSD预防和心理健康与安全相关的工具。从业人员多年的工作经验突出表明,他们对风险评估工具的使用和格式有不同的需求和方法。从业人员报告说,他们使用传统物理工具的量化结果(风险程度、价值),并辅以对社会心理或组织因素的一般观察。尽管许多受访者尚未在其所在部门遇到心理伤害评估的需求,但这被认为是一个迅速崛起的领域,需要有效和可靠的工具。从业人员指出,目前缺乏将认知和社会心理项目结合在一起的工具,这对涵盖多个人体工程学领域的综合工具提出了挑战。在对未来工具开发提出建议的同时,作者还对定性调查过程进行了反思,认为这是风险评估过程中必不可少的一步。未来的研究将需要开发和评估在传统 MSD 评估中整合社会心理因素及其相应工具的测量特性。

Though many respondents had not yet encountered the need for psychological injury assessment in their sectors it was identified as a quickly emerging area citing a need for valid and reliable tools. Practitioners noted a lack of available tools that integrated cognitive and psychosocial items presenting a future challenge for integrated tools that covered multiple ergonomic domains. Along with recommendations for future tool development, the authors reflect on the process of qualitative inquiry as an essential step in the risk assessment process. Future studies will be needed to develop and evaluate measurement properties of integrating psychosocial factors and their respective tools in traditional MSD assessment.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"122 ","pages":"Article 104405"},"PeriodicalIF":3.1,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142513461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy vehicle operators suffer from increased fall risk, potentially due to exposure to whole-body vibration (WBV) that compromises postural control. This study aimed to characterize the relative impacts of multi-axial WBV vs. vertical-dominant WBV on dynamic postural control during sit-to-stand transition and stair descent, following prolonged vibration exposures. We also compared the effectiveness of a standard (single-axial passive suspension) seat with a multi-axial active suspension seat intervention. Vertical-dominant WBV adversely affected dynamic postural control. However, multi-axial WBV had no added adverse effects on postural control compared to vertical-dominant WBV. The multi-axial active suspension system did not outperform the standard seat in mitigating vibration effects on postural control during exposures but led to faster recovery during breaks between exposures. Overall, our results confirmed the negative effects of WBV on dynamic postural control but did not detect any additional negative effects associated with multi-axial WBV when compared to vertical-dominant WBV.
重型车辆操作人员的跌倒风险增加,这可能是由于暴露于全身振动(WBV)影响了姿势控制。本研究旨在描述多轴 WBV 与垂直主导型 WBV 在长时间暴露于振动后从坐到站的过渡和下楼梯过程中对动态姿势控制的相对影响。我们还比较了标准(单轴被动悬挂)座椅与多轴主动悬挂座椅干预的效果。垂直主导型 WBV 对动态姿势控制产生了不利影响。然而,与垂直主导型 WBV 相比,多轴 WBV 对姿势控制没有额外的不利影响。多轴主动悬挂系统在减轻暴露期间振动对姿势控制的影响方面并不优于标准座椅,但在暴露间歇期恢复得更快。总之,我们的研究结果证实了WBV对动态姿势控制的负面影响,但与垂直主导型WBV相比,多轴WBV没有检测到任何额外的负面影响。

The aim of this paper is to identify some of the characteristics of innovation and collective work in different fablab organizations. We first define fablabs through a review of literature, situating related questions in the field of ergonomics and focusing our point of view on individual and collective activity. Secondly, we show how the results of our qualitative analyses (performed on data from interviews and observations of fablab managers, users, and projects from 13 fablabs) reveal 3 main types of fablab organization: community-oriented fablabs, academic fablabs and industrial fablabs, in which different activities are carried out. Fablab activity depends on lab users and the type of design projects carried out. The discussion will focus on the fablab organization findings, including the links between design/innovation project work, collective work and evolving rules, and how all of these aspects might direct activity-centered ergonomics research and actions in the future.
本文的目的是找出不同实验室组织中创新和集体工作的一些特点。我们首先通过对文献的回顾来定义实验室,将相关问题置于人体工程学领域,并将视角聚焦于个人和集体活动。其次,我们将展示定性分析的结果(通过对 13 家实验室的管理人员、用户和项目进行访谈和观察得出的数据)如何揭示出三种主要的实验室组织类型:社区型实验室、学术型实验室和工业型实验室,在这些实验室中开展着不同的活动。实验室的活动取决于实验室用户和设计项目的类型。讨论将集中于实验室组织的研究结果,包括设计/创新项目工作、集体工作和不断演变的规则之间的联系,以及所有这些方面如何指导未来以活动为中心的人体工程学研究和行动。
