The objective of this study was to investigate the effects of a back exoskeleton on joint kinematics and kinetics during assisted manual handling tasks using subject-specific musculoskeletal biodynamic models and model-based analyses. We constructed these musculoskeletal models using OpenSim (Delp et al., 2007), incorporating optical motion capture, ground reaction forces (GRFs) measurements, and humanexoskeleton interactive force input. Our long-term goal is to enable digital modeling and simulation that can aid in the design and development of more effective exoskeletons and safer manual handling practices.

This study investigated the potential for an ergonomic intervention, specifically a prototype height-adjustable stocking cart to reduce the physical demands experienced when stocking shelves. This study compared muscle activity, kinematics, and subjective preferences when participants used the prototype cart versus a traditional, manual stocking method. Nine males and three females participated in this study. A traditional stocking method was compared to the prototype cart method for two types of dry grocery products as they were moved to three different destination shelf heights. EMG data, kinematic data, and subjective feedback generally favored the cart prototype over the traditional method. Bilaterally, anterior deltoid muscle activity was reduced for the cart condition when transferring products to the lower and higher shelves; trapezius activity was reduced for only the higher shelf; right side erector spinae activity was reduced for the lower shelf. The cart primarily benefited the anterior deltoid and trapezius descendens through reduced shoulder flexion. There were interaction effects of cart and shelf height on shoulder and spine kinematics. Questionnaire data showed that participants favored using the prototype. Study results support the continued development of the prototype cart toward a commercially available ergonomic aid for shelf stockers.

Health information like heart rate (HR) and electrocardiogram (ECG) patterns are available to the public on smartwatches; however, there may be a disconnect between these health measures and how users subjectively experience feelings of stress. This study examines the health detection features of two leading smartwatches in the industry, the Apple Watch Series 6 and Fitbit Sense, to determine if these devices may be used to accurately measure stress. Participants engaged in a multi-tasking program (MATB-II) that varied in cognitive workload demand while wearing smartwatches measuring cardiac data. Subjective workload responses resulted in significant differences between low and high workload conditions, indicating an increase in stress. However, both smartwatches were unable to detect significant differences in stress responses between low and high workload conditions. Overall, these results indicate that smartwatch HR and ECGs may not reflect internal feelings of stress and are sensitive to variability in measurement.
公众可以在智能手表上获得心率(HR)和心电图(ECG)模式等健康信息;然而，这些健康措施与用户主观感受压力之间可能存在脱节。本研究考察了业界两款领先的智能手表Apple Watch Series 6和Fitbit Sense的健康检测功能，以确定这些设备是否可以用于准确测量压力。参与者参与了一个多任务项目(MATB-II)，在佩戴测量心脏数据的智能手表的同时，认知工作量需求有所不同。主观工作量反应导致低负荷和高负荷条件下的显著差异，表明压力增加。然而，这两款智能手表都无法检测到低负荷和高负荷条件下压力反应的显著差异。总体而言，这些结果表明，智能手表的HR和ecg可能无法反映内部压力感受，并且对测量结果的可变性很敏感。

Decision accuracy often suffers when missing information and time-pressure are introduced, and there is little consensus on how best to support decision making in these conditions. In this study we compare two naïve decision aides which aim to improve decision accuracy in two environments biasing towards Take-the-Best and Weighted Additive decision strategies. The first support aide slowly acquires missing information for the participants and the second aide provides option suggestions based on estimates of missing information. We found that while both decision aides were able to significantly improve decision accuracy, the aide which provided option suggestions outperformed the decision aide which acquired missing information. We also find that both decision aides have unique mediating effects on the presence of information imbalance.

Case hooks are tools used in distribution centers by selectors to help them reach and pull products located on the back half of a pallet. This study investigated the postural, electromyographic, and usability responses as 4 handle and 3 tip types were used to pull cases forward on a pallet. The data suggest the pistol grip may be most biomechanically advantageous. With the pistol grip, the rake and conventional tips worked well and had good usability scores.

To support new and novel concepts of operations for the anticipated wave of advanced nuclear reactor deployments, human factors and human reliability analysis researchers need to develop advanced simulationbased approaches. The lack of standardized HRA models and human performance data is not new and has outlasted numerous potential solutions. This paper presents a Rancor microworld simulation with computerbased procedures that serve as a framework to classify human behaviors without manual or subjective experimenter coding during scenarios. This method supports a detailed level of analysis at the task level. It is feasible for the collecting large sample sizes required to develop quantitative modelling elements that have historically challenged traditional full-scope simulator study approaches.

Self-driving vehicles (SDVs) are an emerging technology in which consumers have low levels of trust. Researchers/designers can understand and improve consumer trust through research and iterative design, but doing so effectively requires reliable measures. Although general trust-in-automation measures exist, a measure tailored to SDVs may provide a more accurate tool. This study presents work undertaken to create a domain specific trust measure for SDVs. Candidate items were given to 400 participants who rated their trust in an SDV portrayed in a narrative describing a ride in said vehicle. The Trust in Self-driving Vehicles Scale (TSDV) was created by analyzing participants’ responses using psychometric methods. Four factors were extracted from participants’ responses. Five items were retained for each factor to create the TSDV. Initial evidence of the validity of the instrument is presented through the TSDV’s ability to discriminate between a trustworthy and non-trustworthy vehicle, as portrayed in use scenarios.

Background: In warehouse logistics, picking work comprises roughly 60% of the costs, emphasizing the need for efficiency (Matsumoto et al., 2019). Traditionally, workers utilize written instructions, which can be challenging for those less language proficient. The integration of augmented reality (AR) head- mounted displays (HMDs) may enhance accuracy and efficiency (Matsumoto et al., 2019). However, AR HMDs may come with some drawbacks—after extended use, some users report discomfort and decreased performance (Vidovič & Gajšek, 2020). Despite promising improvements in warehouse operations, HMDs’ long-term impacts remain uncertain (Fang et al., 2019). Furthermore, the influence of language proficiency on HMD effectiveness needs exploration (Murauer et al, 2018). In order to fully comprehend the potential and limitations of HMDs, further research is necessary, targeting effective strategies for implementation and optimal AR user interface (UI) design. Objective: This study aims to evaluate an AR HMD system against traditional methods, focusing on its potential to aid non-native English-speaking warehouse workers and boost efficiency and accuracy in picking tasks. Our goal is to ascertain whether an AR aid system, utilizing universal and conformal design principles, can yield superior results in user performance, usability, and situational awareness compared to written instructions. Method: We identified the language-related challenges faced by foreign workers through interviews. Guided by these insights and Ganapathy’s mobile AR guidelines (Ganapathy et al., 2013), we designed an AR solution with universal symbols and intuitive interactions. The AR solution was prototyped using Microsoft HoloLens 2. To evaluate user experience with the proposed system, we conducted a within-subject experiment in a controlled laboratory environment, comparing this AR headset instruction with traditional written instructions. We employed the situation awareness rating technique (SART) questionnaire (Taylor et al., 2017) and system usability scale (SUS) questionnaire (Brooke et al., 1995), along with performance measures, to assess the effectiveness of the proposed system. Results: Our study with 17 participants indicated no significant difference in task completion time between traditional and AR headset instructions. However, AR significantly reduced package identification time ( M=6.89, SE=0.40 vs. M=10.15, SE=0.61). Moreover, people with the AR instructions had no errors while with the traditional written instructions had a total of 2 errors. The proposed AR aid also resulted in enhanced worker situation awareness by allowing them not to divide their attention across job instructions and the dynamic warehouse environment ( M=2.41, SE=0.24 vs. M=3.70, SE=0.35). The AR headset was perceived as easier to use ( M=4.35, SE=0.16 vs. M=3.35, SE=0.17) and better integrated various functions ( M=3.94, SE=0.16 vs. M=2.70, SE=0.19), despite some participants reported a
背景:在仓库物流中，拣选工作约占成本的60%，强调了对效率的需求(Matsumoto et al.， 2019)。传统上，工人们使用书面说明，这对那些语言不熟练的人来说可能是一个挑战。增强现实(AR)头戴式显示器(hmd)的集成可以提高准确性和效率(Matsumoto等人，2019)。然而，AR头显可能会有一些缺点——在长时间使用后，一些用户报告不适和性能下降(vidovikv &Gajš埃克,2020)。尽管有希望改善仓库运营，但hmd的长期影响仍然不确定(Fang等人，2019)。此外，语言能力对HMD有效性的影响需要探索(Murauer et al .， 2018)。为了充分了解头戴式显示器的潜力和局限性，有必要进一步研究，针对有效的实施策略和最佳的AR用户界面(UI)设计。目的:本研究旨在评估AR HMD系统与传统方法的对比，重点关注其在帮助非英语母语仓库工人和提高拣货任务效率和准确性方面的潜力。我们的目标是确定AR辅助系统，利用通用和规范的设计原则，与书面指令相比，是否可以在用户性能、可用性和态势感知方面产生更好的结果。方法:我们通过访谈确定外籍员工所面临的语言相关挑战。在这些见解和Ganapathy的移动AR指南(Ganapathy等人，2013)的指导下，我们设计了一个具有通用符号和直观交互的AR解决方案。增强现实解决方案的原型使用了微软HoloLens 2。为了评估该系统的用户体验，我们在一个受控的实验室环境中进行了一项受试者内实验，将该AR头显指令与传统的书面指令进行了比较。我们采用态势感知评级技术(SART)问卷(Taylor et al.， 2017)和系统可用性量表(SUS)问卷(Brooke et al.， 1995)以及性能指标来评估所提出系统的有效性。结果:我们对17名参与者的研究表明，传统和AR耳机指令在任务完成时间上没有显著差异。然而，AR显著减少了包装识别时间(M=6.89, SE=0.40 vs. M=10.15, SE=0.61)。此外，使用AR指令的人没有错误，而使用传统书面指令的人总共有2个错误。拟议的AR辅助还通过允许他们不将注意力分散到工作指示和动态仓库环境中来增强工人的情况意识(M=2.41, SE=0.24 vs. M=3.70, SE=0.35)。AR头显被认为更容易使用(M=4.35, SE=0.16 vs. M=3.35, SE=0.17)，更好地集成了各种功能(M=3.94, SE=0.16 vs. M=2.70, SE=0.19)，尽管一些参与者报告需要技术援助。结论:人体实验表明，本文提出的AR辅助系统在消除误差、提高易用性和增强仓库外籍工人的态势感知方面是有效的。这项研究还强调了以用户为中心的方法在不同背景下为用户利用技术的重要性。应用:我们的方案在研究范围之外具有广阔的应用前景。它的潜力扩展到各种安全关键领域，包括运输、建筑和军事行动，在这些领域，操作员对动态环境的认识至关重要(Kim等人，2020)。

The proposed AR aid also resulted in enhanced worker situation awareness by allowing them not to divide their attention across job instructions and the dynamic warehouse environment ( M=2.41, SE=0.24 vs. M=3.70, SE=0.35). The AR headset was perceived as easier to use ( M=4.35, SE=0.16 vs. M=3.35, SE=0.17) and better integrated various functions ( M=3.94, SE=0.16 vs. M=2.70, SE=0.19), despite some participants reported a ","PeriodicalId":74544,"journal":{"name":"Proceedings of the Human Factors and Ergonomics Society ...

Introduction: This pilot study investigated the association between trust in healthcare entities and exposure to emerging health misinformation in rural Nebraska. Methods: We surveyed 42 residents of Nebraska to assess their trust in healthcare entities (i.e., the healthcare system, clinicians, Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), and local health departments) and their exposure to emerging health misinformation. Results: Most participants with decreased trust in healthcare entities also reported exposure to health misinformation in the last week. Specifically, 62.5% of participants who reported decreased trust in the healthcare system, 75% in the CDC, 83.3% in the FDA, and 62.5% in the local health department also reported exposure to at least misinformation. Conclusion: The findings suggest that trust is a crucial human factor and is critical in exposure to health misinformation. This highlights the need to prioritize effective communication strategies to build trust.
