TL;DR: The obtained results showed not only that IVR facilitates autonomous learning, but that it can also affect the educational process, pointed out by an increase in its speed, higher effectiveness, positive attitudes, engagement, and motivation on the part of students.
Abstract: Many teachers consider vocabulary acquisition to be a low intellectual activity. However, this subject demands substantial time from both teachers and students, since there is a vast number of words to be learned. In this context, one expects that vocabulary acquisition assisted by Immersive Virtual Reality (IVR) could potentially be used as a powerful learning method. Therefore, this paper summarizes the state-of-the-art concerning the use of IVR in vocabulary acquisition through a systematic literature review. The obtained results showed not only that IVR facilitates autonomous learning, but that it can also affect the educational process, pointed out by an increase in its speed, higher effectiveness, positive attitudes, engagement, and motivation on the part of students.

TL;DR: The state-of-the-art concerning the fire evacuation training in hospitals using VR, through a systematic literature review, is summarized, with emphasis on the need for new VR studies related to hospitalFire evacuation training.
Abstract: A Health Care Establishment (HCE) aims at treating, medicating, curing, and sheltering individuals with health needs. It is not expected that this type of establishment poses a threat to the life of any individual. However, like any other establishment, an HCE is vulnerable to human failures that can represent an imminent danger to an individual’s life. Between 2012 and 2014, approximately 1,100 annual cases of hospital fires were recorded in the USA. Thus, hospital staff training, regarding the evacuation of hospitalized individuals, emerges as an essential practice in reducing the number of deaths and injuries in the face of this kind of disaster. Given this scenario, new technologies have been used in evacuation training, such as Virtual Reality (VR). Therefore, in this paper, we aimed at summarizing the state-of-the-art concerning the fire evacuation training in hospitals using VR, through a systematic literature review. After a rigorous selection process, nine studies were included in the review. These studies addressed, as a majority, some negative aspects concerning traditional evacuation training; thus, encouraging the use of virtual environments for training, where it is possible to immerse the user in extreme simulated fire situations that may occur within a hospital. We also summarized the data regarding the financial costs between traditional and VR training, between methods and technologies for VE training implementation, and some limitations of applying VR technology. In conclusion, emphasis is placed on the need for new VR studies related to hospital fire evacuation training.

TL;DR: In this article, the authors designed a VR simulator specifically focused on hospital evacuation training in the face of a fire situation, which has shown the potential to aid healthcare workers to acquire abilities concerning evacuation.
Abstract: Every establishment is vulnerable to imminent threatening situations. Hence, traditional hands-on evacuation training is paramount to assure the establishments’ safety. However, typical evacuation training has limitations in its ability to reproduce threatening situations. In Health Care Establishments (HCE) such as a hospital, traditional practical training may affect the daily operation. Also, usually, only a small number of healthcare workers participate in regular training. Moreover, the inclusion of features that can threaten patients’ safety — such as fire and smoke — is not allowed. Consequently, the healthcare workers’ engagement and retention of knowledge acquired through training are impaired. Thus, Virtual Reality (VR) emerges as an alternative to traditional evacuation training. Therefore, we designed a VR simulator specifically focused on hospital evacuation training in the face of a fire situation. This VR evacuation training has shown the potential to aid healthcare workers to acquire abilities concerning evacuation in the face of fire.

TL;DR: In this paper, a text entry technique for mobile-based VR on a one-handed ambiguous keyboard is presented, which is an intuitive and user-centered solution that focuses on providing visual and tactile feedback in realtime, improving the typing experience and performance.
Abstract: This paper presents a text entry technique for mobile-based VR on a one-handed ambiguous keyboard. The one-handed keyboard prototype comprises an alternative 16 keys (4 × 4) custom mechanical keyboard with strong tactile bump switches, 3D printed adapted keycaps, and a camera to track which keys the user’s fingers are hovering over. This technique is an intuitive and user-centered solution that focuses on providing visual and tactile feedback in real-time, improving the typing experience and performance. For demonstration purposes, additional devices—a Samsung Galaxy S8, a Samsung Gear VR headset, and a VR hand controller—were used alongside the designed keyboard prototype. This technique has shown to be a potential extension or alternative for short-term text entry compared to standard mobile VR ray-casting selection techniques. Improvements and empirical comparisons based on user studies will compose the next stages of this research.

TL;DR: A systematic review of existing research on virtual reality-based language learning encompassing 32 peer-reviewed studies published between 2015 and 2020 yielded three main language-related findings: multiple exposures to VR are necessary for effective learning, VR is beneficial for contextual vocabulary learning, and perceptions of language learning in VR are positive, but its effectiveness is understudied.
Abstract: Virtual reality (VR) has been shown to be beneficial for learning and for increasing learners’ engagement and motivation. However, aggregations of studies on language learning in high-immersion VR are scarce. This paper offers a systematic review of existing research on virtual reality-based language learning, encompassing 32 peer-reviewed studies published between 2015 and 2020. The study yielded three main language-related findings: (1) multiple exposures to VR are necessary for effective learning; (2) VR is beneficial for contextual vocabulary learning; and (3) perceptions of language learning in VR are positive, but its effectiveness is understudied. We also describe trends in the types of VR technologies, VR content used in language learning, and learners’ perceptions of learning languages in VR. This systematic review is useful for language educators, researchers, and VR app developers.

TL;DR: An in-depth analysis of the safety aspects in various application areas of IIoT such as healthcare, transportation, manufacturing, and mining and discusses diverse forms of technologies, prototypes, systems, models, methods, and applications to ensure the safety of individuals and the risks associated with them.
Abstract: Industrial Internet of Things (IIoT) aims to achieve higher operational and management efficiencies by bridging machinery, equipment, human resources, and all other actors involved in an industrial environment. This bridging enables data flow over an often complex and heterogeneous communication network. It enables timely decision-making, which affects various aspects of the organization such as business, operations, maintenance, safety, stock, and logistics. Despite the plethora of works in the domain of IIoT dealing with the above aspects, very few works deal with safety in industries. Industrial safety, especially whenever it is intertwined with the safety of humans, is a critical domain and holds much scope for improvement in the context of IIoT-based solutions for industrial safety management. Through this survey, we provide a comprehensive overview of the safety issues prevalent in the industries. Subsequently, we classify and provide an in-depth analysis of the safety aspects in various application areas of IIoT such as healthcare, transportation, manufacturing, and mining. Finally, we examine the research gaps in various domains and recommend future research directions. We discuss diverse forms of technologies, prototypes, systems, models, methods, and applications to ensure the safety of individuals and the risks associated with them. The primary aim of this work is to analyze and synthesize the existing researches and acknowledge the applicability of these research works towards safety management using IIoT.
