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。

Failed information exchanges between vehicles and their surroundings can lead to traffic accidents. Drivers often rely on taillights to communicate with following vehicles, but traditional taillights provide limited information and are insufficient in complex traffic situations. Facial expressions, as a universal form of nonverbal communication, offer rich and efficient channels for message delivery. This offers potential to expand current vehicle-to-vehicle interaction methods and enhance driving safety. Therefore, this study conducted an exploratory experiment to enhance inter-vehicle communication through taillight expressions. Using a within-subjects experiment with a 2 (tail light shape) × 3 (tail light expression) design, this study examined the efficacy of taillights in conveying messages. Specifically, we investigated whether rear-end drivers can accurately interpret positive or negative messages conveyed by taillights through different expressions. The process of processing driving-related information involves both perception and analysis stages. In order to capture the neural processes underlying participants' information processing, this study recorded their Event-Related Potentials (ERPs) at these stages separately. The results revealed that negative expression taillights effectively conveyed negative messages through the information processing, and participants responded more swiftly to these messages. However, taillights with positive expressions only effectively conveyed messages during the perception stage. Additionally, linear taillights with negative expressions conveyed the most potent negative messages. The study highlights the potential of taillights to convey information through nonverbal communication, thereby expanding vehicle-to-vehicle interaction. These findings provide a reference for designers and manufacturers seeking to enhance driver–environment communication.

车辆与周围环境之间信息交换失败可能导致交通事故。驾驶员通常依靠尾灯与后面的车辆进行通信，但传统的尾灯提供的信息有限，在复杂的交通情况下是不够的。面部表情作为一种普遍的非语言交流形式，提供了丰富而有效的信息传递渠道。这为扩展当前的车对车交互方式和提高驾驶安全性提供了潜力。因此，本研究进行了一项探索性实验，通过尾灯表情增强车辆间的交流。采用2（尾灯形状）× 3（尾灯表达）设计的受试者内实验，本研究考察了尾灯在传递信息方面的功效。具体来说，我们研究了追尾司机能否通过不同的表情准确解读尾灯传递的积极或消极信息。驾驶相关信息的处理过程包括感知和分析两个阶段。为了捕捉被试信息处理的神经过程，本研究分别记录了被试在这些阶段的事件相关电位（event - associated potential, ERPs）。结果表明，消极表达尾灯通过信息处理有效地传递了消极信息，参与者对这些信息的反应更迅速。然而，带有积极表情的尾灯只能在感知阶段有效地传递信息。此外，带有负面表情的线性尾灯传达了最有力的负面信息。该研究强调了尾灯通过非语言交流传递信息的潜力，从而扩大了车与车之间的互动。这些发现为设计师和制造商寻求加强驾驶员与环境的沟通提供了参考。

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。

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。

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。

Peripheral vision plays a crucial role in assisting drivers with searching for traffic information. Previous studies have explored the association between drivers' peripheral vision and their hazard perception ability, but the impact of peripheral vision on driving behavior remains unclear. Thirty-five participants were recruited to conduct a peripheral vision test and a driving simulation experiment. Then, field of view range, number of correct and incorrect responses, target tracking deviation, and perception time were used to assess the peripheral vision perception ability of individuals. The time to first fixation on hazards, brake reaction time, Standard Deviation of Steering Wheel angle (SDSW), and average speed were selected as dependent variables. Then, the influence of the Peripheral Perception-Response Score (PP-RS) and lateral conflict type on driving performance was assessed. The study finds a significant relationship between the driver's PP-RS and lateral stability, with higher PP-RS scores correlating with smaller standard deviation of steering wheel angle. It also reveals that drivers exhibit a longer first fixation time (p < 0.001) and a delayed reaction time (p = 0.001) when encountering a bicycle crossing compared to a vehicle crossing the roadway. The delay in first fixation time and reaction time are about 0.65 s and 0.67 s, respectively. A similar pattern is observed when pedestrians cross a roadway without a crosswalk. Drivers with higher PP-RS scores can perceive risky conflicts earlier when encountering a crossing vehicle, although they do not always slow down earlier. These findings provide valuable theoretical for improving driver training policies.

周边视觉在帮助驾驶员查找交通信息方面起着至关重要的作用。以往的研究已经探讨了驾驶员周边视觉与危险感知能力之间的关系，但周边视觉对驾驶行为的影响尚不清楚。招募35名参与者进行周边视觉测试和模拟驾驶实验。然后用视野范围、正确和错误反应数、目标跟踪偏差和感知时间来评价个体的周边视觉感知能力。因变量为首次注视危险的时间、制动反应时间、方向盘角度标准差（SDSW）和平均车速。然后，评估周边感知反应评分（PP-RS）和横向冲突类型对驾驶绩效的影响。研究发现驾驶员的PP-RS与横向稳定性之间存在显著关系，PP-RS得分越高，方向盘角度标准差越小。该研究还表明，与横穿马路的汽车相比，司机在遇到自行车人行横道时表现出更长的第一注视时间（p < 0.001）和延迟的反应时间（p = 0.001）。第一次注视时间和反应时间的延迟分别为0.65 s和0.67 s。当行人穿过没有人行横道的道路时，也会观察到类似的模式。PP-RS得分较高的司机在遇到过路车辆时，可以更早地感知到危险冲突，尽管他们并不总是更早减速。这些发现为改进驾驶员培训政策提供了有价值的理论依据。

Large-screen displays have gained increasing popularity and can be operated through both freehand and device-assisted approaches for distant interaction. However, how these interaction approaches work in different large-screen display usage scenarios has seldom been examined. This study was conducted to provide an ergonomic comparison of freehand and device-assisted interactions with large-screen displays under varied postures and user-to-display distances. A within-subjects counterbalanced study design was used, where participants were required to interact with a large-screen display by freehand and two device-assisted approaches under sitting and standing postures and at four user-to-display distances. Two target sizes were also examined. The results showed that, compared with device-assisted approaches, freehand interaction presented poorer ergonomic performance, in terms of lower efficiency, accuracy and perceived usability, and higher workload. Interaction approach significantly interacted with user-to-display distance and posture on task performance and usability dimensions. Freehand interaction was particularly less efficient in standing posture and less effective at closer distances. Posture and user-to-display distance also significantly interacted with each other on task performance. Target size exerted varied effects on task performance by task types.

Relevance to industry

Our results indicate that freehand interaction tends to exhibit poorer ergonomic performance compared with device-assisted approaches, particularly under suboptimal posture-distance conditions. The findings offer valuable insights for improving the design, configuration and adoption of interaction techniques for large-screen displays, especially in distant interaction scenarios.

大屏幕显示器越来越受欢迎，可以通过徒手和设备辅助的方式进行远程交互。然而，这些交互方法如何在不同的大屏幕显示使用场景下工作却很少被研究。本研究的目的是在不同姿势和用户与显示器的距离下，对徒手和设备辅助与大屏幕显示器的交互进行人体工程学比较。采用了受试者内部平衡研究设计，要求参与者在坐着和站着的姿势下，以四种用户到显示器的距离，通过徒手和两种设备辅助方式与大屏幕显示器进行交互。还研究了两种目标尺寸。结果表明，与设备辅助方式相比，徒手交互在效率、准确性和感知可用性方面表现出较差的人机工程学性能，并且工作量更高。交互方式与用户-显示距离和姿态在任务性能和可用性维度上显著交互。徒手互动尤其在站立姿势时效率较低，在近距离时效率较低。姿势和用户到显示器的距离对任务性能也有显著的交互作用。目标大小对任务绩效的影响因任务类型而异。您的研究结果表明，与设备辅助方法相比，徒手交互往往表现出较差的人体工程学性能，特别是在次优姿势距离条件下。这些发现为改进大屏幕显示器的设计、配置和采用交互技术提供了有价值的见解，特别是在远距离交互场景中。

Generative AI is increasingly used in team ideation, but how its design features affect creative performance is unclear. Research on human teams suggests that such effects are mediated by team emergent states (TESs, the team's cognitive and emotional dynamics and feelings). Yet, whether TESs play a similar role in team-AI co-ideation remains unknown. This study explored the effects of AI content strategies (breadth-first vs. depth-first) and participation styles (active vs. passive) on TESs and performance during team-AI collaborative ideation by a mixed-design experiment with 52 students and in-depth interviews with seven professionals from industry. In the experiment, two participants and AI as a team brainstormed and developed design solutions. We found depth-first strategies fostered stronger convergence among ideas and members and further enhanced solution completeness, whereas breadth-first AI increased divergent performance and solution practicability. AI design influenced both cognitive and affective TESs, which predicted objective and subjective performance differentially. This study reveals how the design of generative AI affects human-AI collaborative ideation through the perspective of TES and suggests designing generative AI to adjust to TESs and the creative process.

生成式人工智能越来越多地用于团队创意，但其设计特征如何影响创意表现尚不清楚。对人类团队的研究表明，这种影响是由团队突发状态（TESs，团队的认知和情感动态和感受）介导的。然而，TESs是否在团队-人工智能协同思维中发挥类似作用仍不得而知。本研究通过对52名学生的混合设计实验和对7名行业专业人士的深度访谈，探讨了人工智能内容策略（广度优先vs深度优先）和参与方式（主动vs被动）对团队-人工智能协同思维过程中TESs和绩效的影响。在实验中，两名参与者和AI作为一个团队集思广益，制定了设计解决方案。我们发现深度优先策略促进了思想和成员之间更强的趋同，进一步提高了解决方案的完整性，而广度优先的AI增加了发散性能和解决方案的实用性。人工智能设计对认知TESs和情感TESs都有影响，对客观和主观表现的预测存在差异。本研究通过TES的视角揭示了生成式人工智能的设计如何影响人类-人工智能协同思维，并建议设计生成式人工智能以适应TESs和创造过程。

Various vehicles expose occupants to whole-body vibration (WBV), leading to subjective discomfort in seated individuals. This study investigates the impact of different seat-human contact configurations on subjective discomfort under WBV conditions. Combining the relative magnitude estimation (RME) and absolute magnitude estimation (AME) methods, a static sitting discomfort experiment was conducted before vibration testing to establish subjects' perception of discomfort levels. Under simulated Class C road excitation, five seat-human contact conditions were tested, with data collected on beats per minute (BPM), arterial oxygen saturation (SaO₂), subjective discomfort ratings, and discomfort locations. Results show a significant positive correlation (Spearman's ρ = 0.72, p = 0.002) between the frequency of BPM ‘relative peak’ and subjective discomfort occurrences. Backrest, armrest, and gripping a column reduced the frequency of BPM ‘relative peak’ by 35.3 %, 20.3 %, and 39.8 %, respectively. Headrests and armrests exhibited negative masking effects on discomfort perception, while backrests and gripping a column demonstrated positive masking effects. The optimization of seat design, especially the features of the backrest and column grip, can substantially alleviate the discomfort caused by vibration. This study provides theoretical insights for improving seat-human interaction and enhancing ride comfort.

各种各样的车辆使乘客暴露在全身振动（WBV）中，导致坐着的人的主观不适。本研究旨在探讨不同座位与人接触方式对主观不适的影响。结合相对数量级估计（relative magnitude estimation， RME）和绝对数量级估计（absolute magnitude estimation， AME）方法，在振动测试前进行静态坐姿不适实验，建立受试者对不适程度的感知。在模拟的C级道路激励下，测试了五种座位与人接触的情况，收集了每分钟心跳（BPM）、动脉氧饱和度（SaO2）、主观不适等级和不适部位的数据。结果显示，BPM“相对峰值”频率与主观不适发生率之间存在显著正相关（Spearman's ρ = 0.72, p = 0.002）。靠背、扶手和抓柱分别降低了BPM“相对峰值”的频率35.3%、20.3%和39.8%。头枕和扶手对不适感的掩盖作用为负，而靠背和握柱对不适感的掩盖作用为正。座椅设计的优化，特别是靠背和立柱握把的特点，可以大大减轻振动带来的不适。本研究为改善人座互动、提升乘坐舒适性提供理论依据。

Aircraft cockpits reduce safety risks by providing intelligent human-computer interactions that enhance the naturalness of the pilot's interaction with on-board systems. The goal of this exploratory study was to look into the effect of various interaction modalities on pilot performance, including task performance, workload, and user experience. In an unifactorial within-subjects multilevel trial, 25 male participants performed a take-off task in an aircraft multimodal interaction cockpit platform. The investigation evaluates the differences in pilot performance between gesture interaction and gesture in conjunction with other interaction modalities, using a traditional manipulation interaction modality as a control. Experimental data was analyzed by statistical tests on significance and effect sizes. The results suggest that interaction modality affects task completion time, physical demand, and objective physiological characteristics. Gesture interaction required less mental demand and time than traditional control interaction but had the highest physical demand. Gesture and voice interaction was more advantageous than gesture interaction and traditional control interaction in terms of reducing the pilot's workload and improving the operational experience. The above conclusions indicated that gesture and voice interaction was ideal for the next-generation civil aircraft cockpit for flight tasks.

飞机驾驶舱通过提供智能人机交互来降低安全风险，增强了飞行员与机载系统交互的自然性。本探索性研究的目的是探讨各种交互方式对飞行员绩效的影响，包括任务绩效、工作量和用户体验。在一项单因素受试者内多层次试验中，25名男性参与者在飞机多模式交互驾驶舱平台上执行起飞任务。本研究以传统的操作交互方式为对照，评估手势交互与手势结合其他交互方式在飞行员表现上的差异。实验数据通过显著性和效应量的统计检验进行分析。结果表明，交互方式影响任务完成时间、生理需求和客观生理特征。手势交互所需的心理需求和时间比传统控制交互少，但对身体的需求最高。手势和语音交互在减少飞行员工作量和改善操作体验方面比手势交互和传统控制交互更有利。上述结论表明，手势和语音交互是下一代民用飞机驾驶舱飞行任务的理想选择。
