Assistive technologies may help mitigate bicycle-vehicle crashes; however, these technologies applied to bicycles are understudied. This paper summarizes a preliminary study to identify effective warning signals for a smartphone-based application. This application alerts bicyclists to an imminent collision with a vehicle using a warning signal and gives them additional time to avoid the collision. The signal, however, must be designed to be informative and not otherwise distracting. This work analyzes discussions from experts and stakeholders on the modality and design of warning signals, as well as the efficacy of the mobile application. The experts were presented with visual, audible, and haptic signal options. Text analysis of the focus group transcript shows that flashing visual signals, high pitch auditory tones, and speech messages were most favored by participants.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127323649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exoskeleton moves with the user and can act actively or passively, adding strength to the wearer. In addition, they allow maintaining human dexterity, agility, and adaptability (Bär et al., 2021). Depending on the field of application, these devices can be separated into two main categories: assistive and augmentation exoskeletons. Thus, assistive exoskeletons are designed to assist/replace the impaired parts of the users, restore physical movements, increase independence, and improve patients quality of life. Alternatively, augmentation exoskeletons can be found in industries to improve ergonomics, reduce the risk of exposure to demanding working conditions, prevent work accidents, reduce users’ acute physical stress and strain and increase the operator's efficiency. As well as in military tasks to allow soldiers to carry heavy equipment while walking. Due to its wide use in various applications and the exponentially growing number of research studies in this area, the primary purpose of this article is to provide state of the art regarding lower limb exoskeletons, giving some examples of their general present-day use.Keywords: lower limb exoskeletons; assistive exoskeletons; augmentation exoskeletonsBär, M., Steinhilber, B., Rieger, M.

Therefore, it is essential to find solutions that allow to reduce the exposure to risk factors while providing comfort, without affecting concentration during work.Lower limb exoskeletons can be considered an innovative assistance solution that helps workers perform their tasks by supporting the musculoskeletal system. Lower limb exoskeletons are wearable augmentative devices that work in concert with the user’s movements to provide physical assistance through torques or structural support. The exoskeleton moves with the user and is generally classified as an active or passive system, adding strength to the wearer. Therefore, these devices can be an opportunity to reduce muscular, joint, ligament, and bone stress at work, and potentially prevent WRMSD by physically assisting surgeons.Thus, surgical environments need to be improved to reduce the surgeon’s physical burden and enhance the quality of surgery. On that account, the main goals of this paper are: 1) to provide an overview of the risk factors related to the development of lower limb WRMSD, which are presented in orthopedic surgeries; 2) to explain how adopting lower limb exoskeletons might reduce the load experienced in the lower limbs; 3) identify current roles of existing lower limb exoskeletons; and 4) identify user needs and solutions requirements for future lower limb exoskeleton to be implemented in orthopedic surgery rooms.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134070668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the research proposal is to design a virtual classroom with digital narratives as support to improve reading comprehension in the student body. Digital narratives are a technological resource that can be applied pedagogically, combining content with visual and auditory material, taking advantage of the functionality of virtual classrooms such as Google Classroom, in which the proposal was designed. It is concluded that teachers must identify the problems that their students present in the reading process and implement new methodological strategies, so that learning is different, participatory and innovative, this is where narratives play an important role, such as resource that provides a change in the learning system and support for students with school behind, in addition to strengthening cognitive development with audiovisual stimuli.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123601467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are one of the leading causes of disorders in the lumbar region. One concern of Ergonomics is to reduce the risk of MMH activities and preserve the safety and health of workers. Several assessment methods have been developed to guide MMH risk assessment.The present study aims to analyze the risk of three MMH activities daily performed by warehouse workers. It was developed at a Portuguese Electric Utilities Company. Six assessment methodologies - Revised NIOSH'91 Equation, Hidalgo Model, Shoaf Model, Mital Guide, KIM, and RAMP I – were applied to quantify the risk. A comparative analysis was carried out based on the results obtained by each methodology. After that, ergonomic intervention measures were suggested to eliminate, or at least reduce, the risk.","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125091979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach focused on the development of several technical components able to provide product personalisation as an integrated solution to simplify the interactions between the end-user and the producer. The solution was developed as a web platform for an easy configuration of the product by the user at home and applied to a wheelchair. The finalization of a new order and the assembly procedure of the product is fully digital. This research activity is funded by the EU Project n. 872570 “KYKLOS 4.0 - An Advanced Circular and Agile Manufacturing Ecosystem based on rapid reconfigurable manufacturing process and individualized consumer preferences” (H2020-DT-2018-2020 - Digitising and transforming European industry and services: digital innovation hubs and platforms) which aims at simplifying mass customization while improving circularity and sustainability.MethodsOur Product Parametric Design Methodology was developed through a specific ergonomic analysis of products related to human factors and anthropometry. The use of virtual manikins and simulation of different percentiles, allowed to test and better define correct inputs and parameters for product customization. The solution has been developed and applied to a medical use case and validated and integrated in the KYKLOS 4.0 main platform. The aim was to provide a coherent user experience for the wheelchair ordering and customization, so the user can easily select wheelchair frame and mandatory parts, optional accessories and customize additional elements such as the cushion and footrest. Several Technical Component were developed in order to guarantee the final workflow. The methodology was applied into our “Recommendation Engine” and integrated with the “Users' Behaviour Model”, which use patient’s information, such as anthropometry and behaviour to better define best fitting products and accessories. Additionally, the workflow integrated a specifically designed “3D Modelling Component” which allows direct parts customization.ResultsThe Product Personalization Solution was intended to support the customer in the selection of parts and accessories to fully customize the product and, at the same time, also to support product designer to convert customers’ requests efficiently and smoothly into personalized product specifications, thus providing a complete customer-oriented design for manufacturing with time and cost reduction. The methodology can be considered part of what is called \"ECO-DESIGN,\" which is the design of products based on the sustainable and minimal use of resources and which enables high-quality recycling of materials at the end of the product life cycle. The use of the circular economy concept adopted in the specific pilot case is certainly relevant to the production of customized components for the wheelchair provided by our end-user, as the production of customized comp","PeriodicalId":402751,"journal":{"name":"Human Factors and Systems Interaction","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114847492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trust in automation and autonomy is an important and complex mental construct, which has been demonstrated to be based on several underpinning factors (e.g., attention capacity, user workload, prior experience, user situational awareness, system behaviour, dependability, reliability, predictability, level of automation, failure rate, false alarms and transparency). With the goal of increasing the understanding of the operational tasks in future environments and steering future scientific developments, we designed the Maritime Unmanned Systems Trust (MUST) Game. The MUST Game is an analytical game which goal is to capture beliefs, attitude and perspectives of the participants with respect to the employment of MUS in maritime applications. This game aims at better understanding the relation between trust factors and MUS in missions. This paper presents the results of the analysis of the data collected through the deployment of the MUST Game in three distributed exercises, where the term distributed refers both to time and location. The game explored how players make decisions with respect to MUS deployments as the scenario threat level increases. This allows to capture important information on the trade-offs related to MUS use having an impact on mission planning activities (e.g., endurance, logistics, maintenance, cost, number of assets, security and type of assets). Additionally to the relative importance of the decision factors, important observations emerged during gameplay relating to: (i) the unique considerations of the use of MUS in maritime operations compared to other domains, (ii) potential barriers and the political component of the use of MUS, (iii) the importance of the human component, (iv) the legal and ethical dimensions (i.e., interaction with commercial shipping), (v) the tendency towards employing mixed (manned and unmanned) forces and (vi) the need for decision support systems.
