We introduce principles for designing collaboration among special operation forces (SOF) and future non-human intelligent collaborators (NICs), focusing on interdependence and emergent dynamics of workflow. We discuss a dynamic mixed-initiative human-autonomy teaming (HAT) coordination concept, where multiple military SOF teams collaborate together with autonomous capabilities. We argue that effective tactical actions requires shift of coordination forms, i.e. who is enacting coordination functions, which in military command and control (C2) terminology is formalized as coordination authority. Coordination forms could shift according to a set of requirements and we discuss how to elicit experiences of such coordination from simulated missions where human teammates and/or NICs have had to make choices of coordination form. We formulate a set of hypotheses remaining to be empirically analyzed. We draw on collaboration research investigating socio-technical systems where machine teammates collaborate with human teammates to achieve a common goal.

Using a computer-based face matching task we objectively measured face matching performance (reaction time, sensitivity, accuracy) as a function of prior identity source type (Artificial Intelligence (AI), human, none), prior information accuracy (accurate, inaccurate) and task difficulty (high, low) in professional screeners. Participants were required to judge how similar they thought a pair of faces were, to decide whether the faces in each pair were the same person, and then to judge the difficulty of that decision. Professional screeners were more accurate, faster, and, more sensitive when normative task difficulty was low. Professional screeners were also more accurate, faster, and more sensitive when prior identity source information was accurate. There was no main effect of prior identity source type on performance (there was a trend-level effect). Face matching accuracy positively correlated with normative data from non-professional screeners. Professional screeners were more accurate 80.6% of the time, compared to non-professional screeners.

Hospital patients often develop pressure injuries when lying in bed for an extended time due to relatively high contact pressures breaking down skin tissues. Pressure injuries adversely affect patients by potentially leading to infection and creating advanced health risks. Our prior research identified children experience highest risk of pressure ulcer in the head region. Thus, this study aimed to gather pressure data and create a corresponding model relating foam material properties to predicted interface pressure between the head and a foam mattress overlay surface. Research findings provide data guiding clinicians and designers to mattresses with material properties capable of reducing the incidence of pressure ulcers in children and adults.

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.
