The aim of this study is to review academic papers on the applications of smart glasses. Among 82 surveyed papers, 57 were selected through filtering. The papers were published from January 2014 to October 2020. Four research questions were set up using the systematic review method, and conclusions were drawn focusing on the research trends by year and application fields; product and operating system; sensors depending on the application purpose; and data visualization, processing, and transfer methods. It was found that the most popular commercial smart glass products are Android-based Google products. In addition, smart glasses are most often used in the healthcare field, particularly for clinical and surgical assistance or for assisting mentally or physically disabled persons. For visual data transfer, 90% of the studies conducted used a camera sensor. Smart glasses have mainly been used to visualize data based on augmented reality, in contrast with the use of mixed reality. The results of this review indicate that research related to smart glasses is steadily increasing, and technological research into the development of smart glasses is being actively conducted.

Background: Virtual Reality (VR) and Augmented Reality (AR) technologies provide a novel experiential learning environment that can revolutionize medical education. These technologies have limitless potential as they provide in effect an infinite number of anatomical models to aid in foundational medical education. The 3D teaching models used within these environments are generated from medical data such as magnetic resonance imaging (MRI) or computed tomography (CT), which can be dissected and regenerated without limitations.Methods: A systematic review was carried out for existing articles until February 11, 2020, in EMBASE, PubMed, Scopus, ProQuest, Cochrane Reviews, CNKI, and OneSearch (University College Dublin Library) using the following search terms: (Virtual Reality OR Augmented Reality OR mixed reality) AND [“head-mounted” OR “face-mounted” OR “helmet-mounted” OR “head-worn” OR oculus OR vive OR HTC OR hololens OR “smart glasses” OR headset AND (training OR teaching OR education)] AND (anatomy OR anatomical OR medicine OR medical OR clinic OR clinical OR surgery OR surgeon OR surgical) AND (trial OR experiment OR study OR randomized OR randomised OR controlled OR control) NOT (rehabilitation OR recovery OR treatment) NOT (“systematic review” OR “review of literature” OR “literature review”). PRISMA guidelines were adhered to in reporting the results. All studies that examined people who are or were medical-related (novel or expert users) were included.Result: The electronic searches generated a total of 1,241 studies. After removing duplicates, 848 remained. Of those, 801 studies were excluded because the studies did not meet the criteria after reviewing the abstract. The full text of the remaining 47 studies was reviewed. After applying inclusion criteria and exclusion criteria, a total of 17 studies (1,050 participants) were identified for inclusion in the review.Conclusion: The systematic review provides the current state of the art on head-mounted device applications in medical education. Moreover, the study discusses trends toward the future and directions for further research in head-mounted VR and AR for medical education.

Introduction: The problem of noise-free encoding for an open radio channel is of great importance for data transfer. The results presented in this paper are aimed at stimulating scientific interest in new codes and bases derived from quasi-orthogonal matrices, as a basis for the revision of signal processing algorithms.Purpose: Search for new code sequences as combinations of codes formed from the rows of Mersenne and Raghavarao quasi-orthogonal matrices, as well as complex and more efficient Barker — Mersenne — Raghavarao codes.Results: We studied nested code sequences derived from the rows of quasi-orthogonal cyclic matrices of Mersenne, Raghavarao and Hadamard, providing estimates for the characteristics of the autocorrelation function of nested Barker, Mersenne and Raghavarao codes, and their combinations: in particular, the ratio between the main peak and the maximum positive and negative “side lobes”. We have synthesized new codes, including nested ones, formed on the basis of quasi-orthogonal matrices with better characteristics than the known Barker codes and their nested constructions. The results are significant, as this research influences the establishment and development of methods for isolation, detection and processing of useful information. The results of the work have a long aftermath because new original code synthesis methods need to be studied, modified, generalized and expanded for new application fields.Practical relevance: The practical application of the obtained results guarantees an increase in accuracy of location systems, and detection of a useful signal in noisy background. In particular, these results can be used in radar systems with high distance resolution, when detecting physical objects, including hidden ones.

AbstractThis systematic review aimed to contribute to a better and more focused understanding of the link between the concept of resilience and psychosocial interventions in the migrant population. The research questions concerned the type of population involved, definition of resilience, methodological choices and which intervention programmes were targeted at migrants. In the 90 articles included, an heterogeneity in defining resilience or not well specified definition resulted. Different migratory experiences were not adequately considered in the selection of participants. Few resilience interventions on migrants were resulted. A lack of procedure’s descriptions that keep in account specific migrants’ life-experiences and efficacy’s measures were highlighted.

A smart helmet is a wearable device that has attracted attention in various fields, especially in applied sciences, where extensive studies have been conducted in the past decade. In this study, the current status and trends of smart helmet research were systematically reviewed. Five research questions were set to investigate the research status of smart helmets according to the year and application field, as well as the trend of smart helmet development in terms of types of sensors, microcontrollers, and wireless communication technology. A total of 103 academic research articles published in the past 11 years (2009–2020) were analyzed to address the research questions. The results showed that the number of smart helmet applications reported in literature has been increasing rapidly since 2018. The applications have focused mostly on ensuring the safety of motorcyclists. A single-board-based modular concept unit, such as the Arduino board, and sensor for monitoring human health have been used the most for developing smart helmets. Approximately 85% of smart helmets have been developed to date using wireless communication technology to transmit data obtained from smart helmets to other smart devices or cloud servers.

Although the number of countries that have adopted e-voting has decreased lately, the number of academic publications on e-voting adoption has increased in the last two years. To date, there is no coherent narrative in the existing literature that explains the progress of the research on e-voting adoption. This article aims to answer the following research question: “How has research on the topic of e-voting adoption progressed over the last 15 years?” The article provides a semi-systematic review of 78 studies that were conducted from 2005 to 2020. In this article, I argue that although the studies on e-voting adoption are dominated by a single case study, by research in the United States, and by the positivist paradigm, scholars have employed the term “e-voting adoption” diversely and the research on e-voting adoption has evolved to address more specific research questions. Recommendations for the future agenda of research on e-voting adoption are also discussed.

In this article, the author explores the notion of Collective Intelligence (CI) as an emerging computing paradigm. The article is meant to provide a historical and contextual view of CI through the lenses of as many related disciplines as possible (biology, sociology, natural and environmental sciences, physics) in conjunction with the computer science point of view. During this explorative journey, the article also aims at pinpointing the current strengths and weaknesses of CI-related computational and system engineering design and implementation methodologies of CI-based systems. A non-exhaustive list of case studies set up the stage for CI applications as well as challenging research questions. These can be particularly directed towards the Social Web, as a very prominent example of synergistic interactions of a group of people with diverse cultural and professional backgrounds and its potential to become a platform for the emergence of truly CI-based systems.

Recent advances in technology have made virtual environments, virtual reality, augmented reality, and simulations more affordable and accessible to researchers, companies, and the general public, which has led to many novel use cases and applications. A key objective of human factors research and practice is determining how these technology-rich applications can be designed and applied to improve human performance across a variety of contexts. This session will demonstrate some of the distinct and diverse uses of virtual environments and mixed reality environments in an alternative format. The session will begin with each demonstrator providing a brief overview of their virtual environment (VE) and a description of how it has been used to address a particular problem or research need. Following the description portion of the session, each VE will be set-up at a demonstration station in the room, and session attendees will be encouraged to directly interact with the virtual environment and ask demonstrators questions about their research and inquire about the effectiveness of using VE for research, training, and evaluation purposes. The overall objective of this alternative session is to increase the awareness of how human factors professionals use VE technologies and increase the awareness of the capabilities and limitations of VE in supporting the work of HF professionals.

(1) Background: With vaccination and new variants of SARS-CoV-2 on the horizon, efficient testing in schools may enable prevention of mass infection outbreaks, keeping schools safe places and buying time until decisions on feasibility and the necessity of vaccination in children and youth are made. We established, in the course of the WICOVIR (Where Is the COrona VIRus) study, that gargle-based pool-PCR testing offers a feasible, efficient, and safe testing system for schools in Germany when applied by central university laboratories. (2) Objectives: We evaluated whether this approach can be implemented in different rural and urban settings. (3) Methods: We assessed the arrangements required for successful implementation of the WICOVIR approach in a variety of settings in terms of transport logistics, data transfer and pre-existing laboratory set-up, as well as the time required to establish the set-up. (4) Results: We found that once regulatory issues have been overcome, all challenges pertaining to logistics, data transfer, and laboratory testing on different platforms can be solved within one month. Pooling and depooling of samples down to the individual test result were achievable within one working day in all settings. Local involvement of the community and decentralized set-ups were keys for success. (5) Conclusion: The WICOVIR gargle-based pool-PCR system is so robust and simple that it can be implemented within one month in all settings now or in future pandemics.

Ever since the onset of the Internet and the rapid development in communications, a paradigm shift has been occurring between the human resources and the management systems in place. That shift has already rendered plenty of legacy management systems obsolete and ineffective. Evidently, the acceleration of data transfer speeds has produced a side effect in decreasing the location dependency of the average worker in certain industries, which in turn created a new challenge for the contemporary manager especially when dealing with remote teams and time-management of the same. This work-location decoupling meant that new systems had to be created, new studies to be introduced and plenty of modernization to the legacy control systems had to be implemented. And fast! This paper contains a systematic review of available software solutions for time management, location independency, virtual work and work teams and will provide analytic insight.
