Abstract This paper describes a new approach to analyse the way both hands are placed in relation to the steering wheel. The study is based on a 2D-tracking task, in which the stimulus is a steering wheel angle signal recorded while driving on 7 road geometries in real situations at 30 km/h. Hand movements are measured using a 3D-motion capture system. Data analysis is based on the segmentation of the hand angular position using 8 fuzzy angle windows (labelled as approximately 0°, approximately 45°, etc.), when the hand rests on the steering wheel, one window, else. To obtain information about the coordination aspect, 9 × 9 bivariate windows are considered for each time sample (recorded at 25 Hz); then, the average membership values are computed for each individual driving situation. The individual membership value sets related to the road geometries are studied via Correspondence Analysis, allowing to displaying both the inter- and intra-individual differences and the most discriminating bivariate windows. The methodology with 9 × 9 windows is more complex but implies less information loss than alternative ones e.g. when the two hands are separately analysed, which constitutes 9 + 9 windows and contains no information about the coordination aspect.

Abstract Running-related injuries, specifically overuse injuries, are complex and multifaceted. A different way of thinking is required to fully comprehend why, and how, these injuries occur. The systems thinking perspective offers tools and techniques to capture system-wide interactions in causal, closed-loop structures which may be studied and quantified in a practical way. The value of systems thinking in sport may only realise when pragmatic models follow descriptive, qualitative models. This article instantiates a qualitative, systems thinking perspective of the runner as a complex adaptive system with a hybrid simulation model. The approach is substantiated with principles from physics and physiology and is partially driven by data from a running watch. Results demonstrate that the scientific, reductionist method may be augmented with dynamic, closed-loop thinking and simulation modelling.

Abstract While it is widely agreed that automated and autonomous vehicles may provide safety benefits over vehicles with lower level or no automation, due to other road users there will still likely be situations where a collision is unavoidable. What should a vehicle that is operating autonomously do when it has no choice but to have a collision? And who should decide which vehicle manoeuvre is the most acceptable? These situations create moral dilemmas requiring consideration of the most acceptable and moral action of the vehicle. In this paper we explore current research in this domain and work towards enabling ethical solutions. We identify current experimental work (practical studies rather than theoretical studies) on this problem often contains fundamental flaws due to the lack of real-world validity within the studied scenarios. We argue that morality is highly context dependent and that participants need to be more engaged in the choices they are claiming to make. Suggestions for future work include virtual reality or simulation methodologies which promote immersivity to ensure procedural validity whilst retaining safety. We also identify current guidelines contradict public viewpoint and argue public attitude needs to be better understood to give autonomous and automated vehicle manufacturers confidence in their design.

Abstract This study is aimed at investigating the effect of vibration on health and comfort in tractors with water tankers. The vibration was measured on the floor, seat pan, and backrest of the tractor at different speeds and water levels to optimize for low spinal load in terms of static compressive dose (Sed(8)) and comfort reaction (CR). The experiments were designed using the Taguchi Method and the Response Surface method, and the parameters were optimized using the desirability approach. Models developed to predict Sed(8) and CR showed a significant effect of speed and water level on Sed(8) and CR. The mean Sed(8) exceeded the limits of ISO 2631-5, indicating the probability of adverse health effects. The mean CR indicated uncomfortable exposure based on ISO 2631-1. The optimum ride levels were found at a speed of 8.4 m/s and water level of 3000 L. A confirmatory experiment substantiated the optimum conditions, with output lies within the 95% confidence interval of the predicted responses.

Abstract Robotic swarms comprise component assets operating via local control algorithms which emulate natural swarming behaviors. Scientists are beginning to focus on the human-centered topic of human-swarm interaction. In a novel within-subjects design, we followed this comparatively nascent focus and investigated whether people can detect swarm degradations in assets flocking via consensus, their accuracy in estimating those degradations, and their confidence in those estimates. We also assessed open-ended responses to shed light on the strategies people may use to detect swarm degradations. Participants were recruited online and viewed 21 randomized simulations, each 30 seconds in duration with varying proportions of asset degradation. Results showed that the proportion of asset degradation did have an effect on the aforementioned criteria. Qualitative themes showed preliminary evidence that participants used common strategies to detect the time and degree of swarm degradation. However, we did not find evidence of a linear effect of the degradation manipulation on criteria of interest, which did not support our expectations. We discuss limitations and future research perspectives in detail, which we believe provide fodder for future work to investigate human-swarm interaction at a more granular level.

Abstract A key psychological component of interactions in both human-human and human-automation relationships is trust. Although trust has repeatedly been conceptualized as having a component of risk, the role risk plays, as well as what elements of risk impact trust (e.g., perceived risk, risk-taking propensity), has not been clearly explained. Upon reviewing the foundational theories of trust, it is clear that trust is only needed when risk exists or is perceived to exist, in both human-human and human-automation contexts. Within the limited research that has explored human-automation trust and risk, it has been found that the presence of risk and a participant’s perceived situational risk impacts their behavioural trust of the automation. In addition, perceived relational risk has a strong negative relationship with trust. We provide an enhanced model of trust to demonstrate how risk interacts with trust, incorporating these distinct perceived risks, as well as risk-taking propensity. This model identifies the unique interactions of these components with trust based on both the theory reviewed and the studies that have explored some aspects of these relationships. Guidelines are provided for improving the study of human-automation trust via the incorporation of risk.

Abstract Background Most dental procedures are time-taking and also need professional skills to obtain the desired results. To achieve success in the dental profession, one needs to modify the previous working conditions. Objective A comprehensive, systematic review was conducted on the available literature to clarify the advantages of the proprioceptive derivation over the conventional approach. Methods Three major scientific databases were used as search engines like Medline/PubMed and EBSCOhost by following three main criteria. The search criteria were based on the proprioceptive derivation concept used in dentistry and the change in the dental workstation environment for an effective way of performing dentistry. They modified work postures that reduce the risk of work-related musculoskeletal diseases. Results The Proprioceptive derivation approach resulted in improvement in all the three objectives followed in this systematic review. Applying the proprioceptive principles resulted in comfort and work efficiency in performing dental procedures. Conclusion Applying the Pd concept to dental practice reduces work-related musculoskeletal disorders and improves dental clinicians’ work efficiency and longevity.

Abstract The current paper proposes a novel taxonomy of latent hazard anticipation by distinguishing modal, strategic, tactical, and operational hazard anticipation skills. Novice drivers face an increased risk of being involved in fatal motor vehicle crashes. Research involving both on-road and driving simulator studies suggests that novice drivers are especially poor at anticipating latent hazards. We reviewed and synthesized previous works on hazard anticipation in young drivers. Modal hazard anticipation skills are broader in nature and more applicable to the general traffic, roadway, and environmental conditions, while strategic, tactical, and operational hazard anticipation skills are more scenario-specific and necessary when navigating a potentially safety-critical situation. It is known that error-based feedback training programs can improve both tactical and strategic, but not yet operational and modal hazard anticipation abilities of novice drivers. Future research should explore individual differences in the effectiveness of training interventions for young novice drivers.

Abstract Driving distraction is an important cause of traffic crashes, as it diverts the driver’s attention away from the primary driving task. This paper studies the engagement frequency of drivers in distracting activities due to modern devices used in vehicle dashboards, to improve roadway safety. Data were collected from Jordanian drivers through two questionnaires. In the first, a wide range of distracting activities and their influence on crashes were considered. The focus of the second questionnaire was on factors affecting the driver’s distraction by the Human-Machine Interface (HMI) screens in vehicles. The collected data were analyzed statistically. Several significant factors were found that distract drivers, including but not limited to the use of HMI screens, the driver’s age, experience and occupation. This paper raises public awareness of the risks of distracted driving due to modern devices, in order to boost traffic safety.

Abstract Patient satisfaction is an important and frequently used outcome measure for the quality of healthcare services. Any increase in patient satisfaction scores translates directly into an improved reputation, customer loyalty, profitability, and growth. This study investigates the effect of a well-designed work environment on medical laboratory employee satisfaction and in turn on patient satisfaction. The Quality Function Deployment methodology is used to translate the voice of patients into a set of critical to quality ergonomic aspects that are converted to prioritized and actionable ergonomic processes. By understanding the importance of ergonomic process elements of medical laboratory employee satisfaction and their effect on patient satisfaction level, it is possible to make informed decisions about the workplace elements that need to be considered for improvement. The results of this study highlight the role and responsibilities of healthcare execution managers in creating ergonomics-based organizational policies and strategies, leading to improved healthcare quality performance and financial results.
