Mental health and substance abuse patients face many challenges in receiving effective long-term outpatient behavioral therapies, including issues related to accessibility and personalized care. Mobile health technologies, particularly those integrating virtual reality (VR), are increasingly becoming more accessible and affordable, thus providing a potential avenue to deploy outpatient behavioral therapy. This paper proposes a method to address the aforementioned challenges by personalizing and validating VR simulation content for behavioral therapy. An initial demonstration will be performed for tobacco cessation, which is a critical public health treatment area for mental illness and substance abuse. The method empirically builds smoker personas from theoretically grounded survey content. The personas are then used to design and pilot VR simulation modules tailored to behavioral interventions, which will be tested in the patient population. The VR simulation will record a subject’s emotions and brain activities in real-time through subjective (surveys) and objective (neurophysiology) measures of emotional response. The overall goal of the study is to validate the VR content by demonstrating that significant differences are seen in emotional response when presenting content personalized for the patient.

Recently, severe environmental changes, such as global warming, climate change and environmental pollution, have become expected, and thus environmental education is becoming essential. The purpose of environmental education is to instill awareness in students to recognize and solve environmental problems. Virtual reality provides students with a spatial and temporal experience similar to reality, and it can increase their understanding of knowledge through immersion and interaction compared to traditional learning. In previous studies, virtual reality for education has mainly focused on experience, but it is difficult to find examples for environmental education. Hence, this research proposed an immersive virtual reality simulation for environmental education based on the virtual ecosystem model. It also presented two applications developed based on this simulation. This research aims at encouraging students’ active participation and motivation to solve the environmental problems while experiencing the results of interaction related to environmental factors in a virtual environment.

The adoption of virtual reality in manufacturing system simulation had proved its effectiveness in bridging up to the gap between different areas of expertise, especially in product design and manufacturing. Virtual reality had enclosed human–machine interface by enabling the user to be immersed into the virtual environment and experience real-time interaction with the virtual objects. In this article, an implementation of virtual reality in cellular manufacturing system simulation is presented. By utilizing the features of visualization and real-time interaction of virtual reality technology, the manufacturing process of a product had been visualized while the real-time control on the product traveling path based on the user’s input was performed and the corresponding activities that related to the change of traveling path had been predicted in the virtual environment. Through the study, simulation of the manufacturing system in virtual reality showed its potential as a powerful decision support system in process planning and scheduling. Various process planning and schedules can be planned through the virtual environment, while the product traveling distance can be obtained from the developed system.

The purpose of this study was to develop prototype of virtual reality(VR) simulation with malocclusion models and evaluate its applicability. Task abilities, task completion time, and a satisfaction survey were compared between dentist trainees and dental students. Participants were instructed to observe virtual malocclusion models and then performed three tasks to diagnose the type of malocclusion, determine clinical findings and develop treatment plans. Their satisfaction with the simulation experience were evaluated using a questionnaire containing five questions. Task abilities of trainees related to clinical features and treatment plans were significantly higher than that of students(<i>p</i> < 0.01). In both groups, the task completion time for the second case was significantly reduced compared to that for the first case(<i>p</i> < 0.01). The satisfaction survey showed high scores and positive responses for this simulation in both groups. If the prototype of VR simulation is continuously advanced, it will be applicable for orthodontic education in pediatric dentistry.

Full textAbstract:
This article discusses factors related to simulation sickness in virtual reality driving simulations with head-mounted displays. Simulation sickness is a well-known phenomenon that has physiological effects on users, such as disorientation, headache, and nausea. There are three major theories why simulation sickness arises. Previous research on this phenomenon has mostly concentrated on driving or flying simulators with standard computer displays. It is, therefore, possible to conclude that any simulated environment could have such an effect, and virtual reality should not be considered an exception to such problems. While virtual reality has had and will continue to have a positive impact on the development and testing of new automotive interior concepts, simulation sickness is a significant drawback. Despite the advances in technology, discomfort from using head-mounted displays has yet to be resolved. A review of these displays in the context of virtual reality driving applications over the recent years will be presented. Moreover, characterization and comparison of approaches to mitigate simulation sickness will be given in the text. Concluding suggestions for future work on the correlation between simulation sickness and a virtual driving environment will be provided.

Abstract Introduction Flying is a prevalent but infrequent experience in dreams. Despite a broad interest in such unique dream experiences, there is still no experimental procedure for reliably inducing them. Our study aimed 1) to induce flying dreams in the laboratory using virtual reality (VR), 2) to examine phenomenological correlates of flying dreams, such as lucidity and emotions and 3) to investigate the dynamics of dreamed gravity imagery in relation to participant state and trait factors. Methods A total of 137 healthy participants (24.01±4.03 y.o.; 85 F; 52 M) took part in a custom-built immersive VR task in which they learn how to ‘fly’ as precisely and quickly as possible, engaging vestibular, motor and visuo-spatial systems. Dreams were collected a) from home dream journals for 5 days before and 10 days after the laboratory VR task and b) after a 90-min morning nap in laboratory. Dream reports were scored by 2 independent judges for flying and other gravity-related imagery. Linear mixed models statistics were used to compare dreams from this cohort with a separate control cohort (N=52) that followed a similar protocol in the same lab but did not undertake a virtual flying task. Results The VR task successfully increased the likelihood of experiencing flying in dreams from both the laboratory nap (7.1%) and the following night (10.6%) compared to baseline (1.3%) and the control cohort on those days (Lab: 2.4%; following night: 0%). In contrast, the occurrence of other gravity imagery showed no differences. Flying dreams were altered qualitatively, exhibiting higher levels of lucid-control and emotional intensity after VR exposure. Moreover, various factors such as sex, prior dream experiences and sensory immersion in VR differentially modulated flying dream induction. Conclusion Our findings provide both quantitative and qualitative insights into flying dreams that may facilitate understanding of these typical dream experiences and future developments in dream flight-induction technologies.

The objective of this review was to provide a summary of virtual reality (VR) simulation for emergency management (EM) teams and suggest future research agenda items. A systematic literature review was conducted using three databases: PsycINFO, Compendex (Engineering Village), and Web of Science. A total of five articles met inclusion criteria and thus were reviewed here. Our review identified four common aspects of VR-based EM team simulation: coordination, communication, decision-making, and situation awareness. Future research is recommended to investigate other aspects of team cognition and collective characteristics as to how these are related to team performance. The level of fidelity of the VR simulation was identified as an important factor to consider when designing VR simulations for different populations with varying experience level. The adoption of more immersive VR systems would be beneficial to improving ecological validity. Moreover, a deep analysis of fidelity and simulation effectiveness is recommended.

Full textAbstract:
This article analyzes the use of virtual reality exposure therapy (VRET) to treat combat-related posttraumatic stress disorder. In this therapeutic practice, patients wear a head-mounted virtual reality display and enter a simulation designed to incarnate their triggering memories. VRET visualizes the formerly invisible site of psychotherapy, achieving a medical aspiration that has been pursued since the turn of the twentieth century. This visualization subjects therapy to a mode of surveillance and mediates the conditions in which trauma is processed. In this article, I consider how VRET’s user interfaces produce feelings of agency that reconfigure how power is distributed at the scene of therapy. I situate this novel practice at the intersection of two technological histories: the industrial history of the military-entertainment complex that spawned VRET, and the theoretical history that unites psychoanalysis and computation in their mutual ambition to formalize thought. Contending that neither of these histories can be disarticulated from the violent projects they have sustained, I interrogate the politics of a practice that visualizes and virtualizes psychotherapy, arguing that VRET processes trauma according to a militarized worldview.

Full textAbstract:
Usability testing is expensive in some domains due to the resource requirements that go hand in hand with taking a complex context of use into account. Crisis-related research is one such domain, typically requiring the reenactment of an extensive crisis scenario. To lessen the resource requirements and provide a more flexible setup geared towards testing, crisis scenarios can be reconstructed as virtual reality simulations. This paper outlines the development of an initial prototype of such a simulation following the design science method. The prototype is used to test if injecting an item that will be tested into the simulation affects the realism of the virtual reality crisis simulation. The realism was measured in a within-subject experiment and equivalence tests showed that injecting a representation of a simple app had no significant influence on the realism of the simulation.

Rehabilitation is the process related to the recovery, maintenance or improvement of physical mental and / or cognitive skills necessary to carry out daily activities. Virtual reality therapy, virtual reality (VR) immersion therapy, simulation therapy or virtual reality exposure therapy is an intervention method of using virtual reality technology for psychological or occupational therapy. The possibility of simulating situations necessary for the treatment, controlling variables and reducing the patient’s exposure to risks are popular factors for this tool. Many studies indicate that therapy with the aid of virtual reality brings great benefits to the patient. In this article, we present, through a review of 117 articles, the feasibility of applying VR in treatments with clinical trial methodology, identifying through the "Patient, Intervention, Comparison and Outcomes" the characteristics, population, treatment time, forms of comparison and if the results obtained are effective. The characteristics identified during the process show that virtual reality applied to therapies can be used without negative interference in the treatment. In addition, the results show that VR in rehabilitation treatments are motivating and show better results than traditional treatments.

Abstract After the success of virtual reality (VR) applications in supporting exposure-based and psychoeducational cognitive behavioural therapy for various mental illnesses, the technology is also gaining traction in addiction medicine. This paper will describe the concept behind a custom-developed VR simulation for this application with a particular emphasis on alcohol-related addictive disorders. Using Unreal Engine 4, an exposure simulation and a scenario for learning and applying coping strategies were developed for the Oculus Quest. Because of the common association of supermarkets with the procurement of alcohol among addicts, a small shop was implemented as initial scenario. Since the feeling of presence is an important parameter in the quality assessment of a simulation, the degree of immersion was evaluated in initial practical tests after development. In surveys with ten healthy testers, the majority showed a feeling of immersion. Cybersickness and unrealistic collision physics were identified as disruptive factors to the extent of immersion. This work provides the basis for a novel concept for addiction therapy which focusses on a fusion of playful psychoeducation, adjustable exposure, and the internalization of coping strategies with the help of multisensory biofeedback as well as the documentation of the objective physiological measurements for assessment of therapy success. The aim is to best possible address the specific requirements for clinical and home use in terms of self-containment, immersion, and ease of use. To evaluate and exploit the scientific potential of this concept scientific studies and technical improvements to both simulation and hardware are required.

Full textAbstract:
Background A critical component of disaster preparedness in hospitals is experiential education and training of health care professionals. A live drill is a well-established, effective training approach, but cost restraints and logistic constraints make clinical implementation challenging, and training opportunities with live drills may be severely limited. Virtual reality simulation (VRS) technology may offer a viable training alternative with its inherent features of reproducibility, just-in-time training, and repeatability. Objective This integrated review examines the scientific evidence pertaining to the effectiveness of VRS and its practical usefulness in training health care professionals for in-hospital disaster preparedness. Methods A well-known 4-stage methodology was used for the integrated review process. It consisted of problem identification, a literature search and inclusion criteria determination, 2-stage validation and analysis of searched studies, and presentation of findings. A search of diverse publication repositories was performed. They included Web of Science (WOS), PubMed (PMD), and Embase (EMB). Results The integrated review process resulted in 12 studies being included. Principle findings identified 3 major capabilities of VRS: (1) to realistically simulate the clinical environment and medical practices related to different disaster scenarios, (2) to develop learning effects on increased confidence and enhanced knowledge acquisition, and (3) to enable cost-effective implementation of training programs. Conclusions The findings from the integrated review suggested that VRS could be a competitive, cost-effective adjunct to existing training approaches. Although the findings demonstrated the applicability of VRS to different training scenarios, these do not entirely cover all disaster scenarios that could happen in hospitals. This integrated review expects that the recent advances of VR technologies can be 1 of the catalysts to enable the wider adoption of VRS training on challenging clinical scenarios that require sophisticated modeling and environment depiction.

Virtual reality (VR) technology provides a human-computer interface that allows participants to interact naturally with digital objects which are represented as three-dimensional images that occupy positions in a three-dimensional world. Related to problems of engineering design and manufacturing, this new technology offers engineers the ability to work with computer models in a three-dimensional, immersive environment. This paper describes a virtual reality application where the results of a discrete event simulation of a manufacturing cell are integrated with a virtual model of the cell to produce a virtual environment. The program described in this paper, the VRFactory, combines results from a commercial discrete event simulation program, SLAM II, with a virtual environment. This allows the user to investigate, using three-dimensional computer models, how various changes to the manufacturing cell affect part production. This investigation is performed while immersed in a computer-generated three-dimensional representation of the cell. Existing discrete event programming software allows only two-dimensional views of the factory as the parts progress through the simulation. Parts are shown only as primitive geometric shapes on the computer monitor and instantaneously move from one station to the next. The virtual environment implementation of the SLAM II results allows users to experience the simulation in a fully immersive three-dimensional digital environment. The virtual environment used here is a CAVE™-like projection screen-based facility called the C2, which is located at Iowa State University. This paper describes the creation of the VR model of the manufacturing cell, the animation of the environment and the implementation of the results of the discrete event simulation.

Training simulators have been gradually evolving in the direction of software, virtualization, networking, and multiplatform in recent years, with the continuous development of hardware and software technologies, particularly the maturity of VR (Virtual Reality) related technologies. The network intrusion program allows remote hackers to take control of the system, posing a serious threat to the network and computer security. As a result, this paper proposes a VR-based ID (intrusion detection) simulation training system. This paper proposes an ID model based on CNN (Convolutional Neural Networks) and LSTM to address these issues (Long Short-term Memory Networks). This model oversamples data from unbalanced data sets, reducing the difference in category data and thus improving the ID model’s performance and existing detection methods to compensate for the flaw. 3DSMAX technology is used to simulate the process visualization scene, as well as some key equipment models and signal transmission simulations, during the system design and implementation process. The experimental results show that CNN LSTM outperforms BP, and the overall evaluation index F1 has significantly improved, particularly the F1 index of D4. CNN LSTM outperforms GA (genetic algorithm) by 12.75 percent and BP by 14.07 percent. The system essentially accomplishes the anticipated simulation training goal, and the simulation training effect is impressive.

Purpose: This study aimed to investigate the effects of virtual reality used in maternal-child nursing clinical practicums on nursing students’ competencies through a systematic review.Methods: The inclusion criteria were peer-reviewed papers in English or Korean presenting analytic studies of maternal-child nursing practicums using virtual reality. An electronic literature search of the Cochrane Library, CINAHL, EMBASE, ERIC, PubMed, and Research Information Sharing System databases was performed using combinations of the keywords “nursing student,” “virtual reality,” “augmented reality,” “mixed reality,” and “virtual simulation” from February 4 to 15, 2022. Quality appraisal was performed using the RoB 2 and ROBINS-I tools for randomized controlled trials (RCTs) and non-RCTs, respectively.Results: Of the seven articles identified, the RCT study (n=1) was deemed to have a high risk of bias, with some items indeterminable due to a lack of reported details. Most of the non-RCT studies (n=6) had a moderate or serious risk of bias related to selection and measurement issues. Clinical education using virtual reality had positive effects on knowledge, skills, satisfaction, self-efficacy, and needs improvement; however, it did not affect critical thinking or self-directed learning.Conclusion: This study demonstrated that using virtual reality for maternal-child nursing clinical practicums had educational effects on a variety of students’ competencies. Considering the challenges of providing direct care in clinical practicums, virtual reality can be a viable tool that supplements maternal-child nursing experience. Greater rigor and fuller reporting of study details are required for future research.

Full textAbstract:
Virtual Reality (VR) is becoming a mature technology field. To understand its origins and foresee strategies, a study on the last decade of papers published in the Brazilians´ most prominent symposium (the SVR – Symposium on Virtual and Augmented Reality) has been carried out. Papers were classified according to subject of study (including application domains, sub-areas and technologies, among others) as well asresearch structure (including authorship counts and geographical distribution, research approaches, among others). The study shows that health related applications have received most of the attention although techniques and tools proposal have raised the most recently which could be related to the lowlevel programming languages and frameworks preferences found to this community. The number of Augmented Reality (AR) papers has grown steadily and a great variety of underlying knowledge fields (such as 3D interaction and real-time simulation) is a persistent aspect of SVR. Data also show that expected shift from VRML to other 3D Web technologies have already happened. Although oversees participation has been not constant, papers published in English has proven stable in SVR editions. Few institutions from Southeast have dominated the research area but another few from Northeast have just surpassed them. Regarding the research, a lack of higher-level maturity research approaches has been noticed. In addition, it was found difficult to assess the relevance of papers to other researches due to poor abstracts and no centralized database of papers. The analysis of 262 papers suggest that (i) by improving the research budget to the area could impact productivity; (ii) a centralized database would facilitate recovering past contributions and; (iii) that enforcing more scientifically rigorous papers with better abstracts and written in English could raise the visibility of Brazilians´ research in VR/AR.

With the rapid development of the national economy and the improvement of people’s living standards, physical fitness and health have attracted people’s attention and become an important topic in people’s daily life. Virtual reality technology is a new technology that uses computer to build virtual environment, belonging to simulation technology, which is an extremely important direction in this field. This paper aims to study the importance of the national fitness sports relying on virtual reality technology in the development of sports economy. The related concepts of virtual reality technology and the related meanings of national fitness are introduced. The characteristics of the office population are analyzed to understand the daily behavior habits, health status, and common diseases of the target population. Meanwhile, the traditional home fitness equipment and virtual home fitness equipment are collected and compared. The problems of the existing home fitness equipment are understood so as to discover the direction of subsequent design. Then, through interviews, questionnaires, and on-the-spot research, the target users and the product usage environment are investigated in depth. The pain points and needs of users are found and the needs of office workers for fitness products are summarized. The experimental results showed that in the national fitness sports relying on virtual reality technology, 80% of the respondents believed that the integration of somatosensory technology into fitness equipment has a positive effect on improving fitness.

Full textAbstract:
The documentary concept is a 'notoriously slippery eel,' or even the slipperiest one in the history of cinema (Kahana, 2016). With the involvement of virtual reality in the production of documentaries, the dialectic between virtuality and authenticity makes this concept even more elusive. Does documentary exist in VR films? When the spaces and mise-en-scène of the documentary are all artificially created through computing software, can it still be considered an authentic form of a documentary? How can this sub-genre of documentary continue to exist as a kind of proclaimed ‘non-fiction’ when the film is based entirely on fictional visual input? This paper aims to put the discussion on visual realities aside and provides a perspective for understanding how real auditory characteristics are built up in virtual environments (VE) of virtual reality documentaries. We develop this argument in three parts. In the first part, we define a virtual reality documentary and distinguish it from other virtual reality films based on Bill Nichols’s analysis of the boundary between traditional documentary and other types of films. Then, we describe the design and implementation of the aural simulation systems with HRTF (Head-Related Transfer Function) in virtual reality documentary sound design to illustrate how it could reproduce realistic physical hearing for viewers. In the final part, we explore the concept of ‘soundscape’ as it applies to VR documentaries, attempting to show that the sense of authenticity in the audition is related to generating the genius loci (spirit of place) of the viewers based on the case analysis of Anne Frank House VR. Such a spirit of place is embedded in the hearing experience of those who experienced it.

Full textAbstract:
Skeleton tracking based on multiple Kinects data fusion has been proved to have better accuracy and robustness than single Kinect. However, previous works did not consider the inconsistency of tracking accuracy in the tracking field of Kinect and the self-occlusion of human body in assembly operation, which are of vital importance to the fusion performance of the multiple Kinects data in assembly task simulation. In this work, we developed a multi-Kinect fusion algorithm to achieve robust full-body tracking in virtual reality (VR)-aided assembly simulation. Two reliability functions are first applied to evaluate the tracking confidences reflecting the impacts of the position-related error and the self-occlusion error on the tracked skeletons. Then, the tracking skeletons from multiple Kinects are fused based on weighted arithmetic average and generalized covariance intersection. To evaluate the tracking confidence, the ellipsoidal surface fitting was used to model the tracking accuracy distribution of Kinect, and the relations between the user-Kinect crossing angles and the influences of the self-occlusion on the tracking of different parts of body were studied. On the basis, the two reliability functions were developed. We implemented a prototype system leveraging six Kinects and applied the distributed computing in the system to improve the computing efficiency. Experiment results showed that the proposed algorithm has superior fusion performance compared to the peer works.

Augmented reality is well known for extending the real world by adding computer-generated perceptual information and overlaid sensory information. In contrast, simulation worlds are commonly closed and rely on artificial sensory information generated by the simulator program or using data collected off-line. In this work, a new simulation paradigm is introduced, providing augmented virtuality by integrating crowd sensing and social data mining in simulation worlds by using mobile agents. The simulation world interacts with real world environments, humans, machines, and other virtual worlds in real-time. Mobile agents are closely related to bots that can interact with humans via chat blogs. Among the mining of physical sensors (temperature, motion, position, light, …), mobile agents can perform Crowd Sensing by participating in question–answer dialogs via a chat blog provided by a WEB App that can be used by the masses. Additionally, mobile agents can act as virtual sensors (offering data exchanged with other agents). Virtual sensors are sensor aggregators performing sensor fusion in a spatially region.

The purpose is to convert the contents of the grotto murals into a digital vision based on deep learning (DL) and virtual reality (VR) technology to protect the precious grotto murals. The grotto murals are analyzed and modeled by introducing the related concepts of the digital library, using VR technology, and taking the cultural relics data acquisition technology as the basic framework. Then, the cultural relics information collection technology under DL is combined with VR technology, the color and materialization concepts of grotto murals are integrated, and a digital recognition model of grotto mural restoration and simulation is constructed. The color analysis scheme of grotto murals is established. Through the analysis of color and material, the comprehensive recognition rate of this color model can reach 70%, and the material recognition of color painting can also ensure one-to-one restoration. Besides, the model can be applied to the simulation and restoration of grotto murals and provide some help for the protection of grotto murals. This paper has practical application value for the protection and restoration of mural art.

AbstractLandfalling hurricanes in the United States can inflict extreme damage and loss of life. The latter, particularly, can be caused by a host of socioeconomic factors, including insufficient understanding of risk by individuals expected to be impacted by the storm. Thus, we test the use of an emerging technology, virtual reality (VR), to enhance the communication of real-time risk from a hurricane forecast to make landfall. In this pilot study, individuals are presented with a hypothetical scenario where a major hurricane is forecast to impact their community within 48–72 h. The survey includes two different types of warning products related to the hypothetical hurricane: static text and maps emulating those traditionally used by media outlets and local officials to communicate risk, and a VR video simulating a hurricane landfall in a residential neighborhood. We survey two groups of equal size (each n = 62), one viewing both the VR simulation and traditional products, and the other only the latter. Each group was then asked a series of Likert-scale and open-ended questions to assess the effectiveness of both products. We determine that participants viewing both the VR and traditional products are significantly more likely to take action in preparation for the hypothetical landfall than those being exposed to just the traditional products. These results demonstrate that VR can be a useful component of hurricane warning products, and further work can be done to improve the effectiveness of such products and assess how broader segments of the population can access this information.

Full textAbstract:
Virtual Reality (VR) technology is increasingly used to simulate and study human-robot interaction (HRI) because of its low cost and minimal risk to participants. The current study investigated whether perceived safety and safety-related behaviors during human-robot interaction can be adequately examined in virtual environments. Two prior studies that examined perceived safety and proxemics behavior during human-robot interaction in real environments were replicated in virtual environments using Head-Mounted Display (HMD) VR. Our results indicated that although perceived safety during virtual human-robot interaction is higher than during physical interaction in some situations, the virtual simulation of robots induced safety perception and behaviors comparable to those found in real environments and some of the findings of the previous human-robot interaction studies were replicable in a virtual environment. These findings suggest that VR simulation is a valid and useful method for research and worker training; however, it may be less sensitive than real environments.

Full textAbstract:
Deaths due to heart diseases are a leading cause of death in Mexico. Cardiovascular diseases are considered a public health problem because they produce cardiorespiratory arrests. During an arrest, cardiac and/or respiratory activity stops. A cardiorespiratory arrest is rapidly fatal without a quick and efficient intervention. As a response to this problem, the VirtualCPR system was designed in the present work. VirtualCPR is a mobile virtual reality application to support learning and practicing of basic techniques of cardiopulmonary resuscitation (CPR) for experts or non-experts in CPR. VirtualCPR implements an interactive virtual scenario with the user, which is visible by means of employment of virtual reality lenses. User’s interactions, with our proposal, are by a portable force sensor for integration with training mannequins, whose development is based on an application for the Android platform. Furthermore, this proposal integrates medical knowledge in first aid, related to the basic CPR for adults using only the hands, as well as technological knowledge, related to development of simulations on a mobile virtual reality platform by three main processes: (i) force measurement and conversion, (ii) data transmission and (iii) simulation of a virtual scenario. An experiment by means of a multifactorial analysis of variance was designed considering four factors for a CPR session: (i) previous training in CPR, (ii) frequency of compressions, (iii) presence of auditory suggestions and (iv) presence of color indicator. Our findings point out that the more previous training in CPR a user of the VirtualCPR system has, the greater the percentage of correct compressions obtained from a virtual CPR session. Setting the rate to 100 or 150 compressions per minute, turning on or off the auditory suggestions and turning the color indicator on or off during the session have no significant effect on the results obtained by the user.

It is my pleasure to introduce you the first issue of the SBC Journal on 3D Interactive Systems (JIS) in 2012. This issue contains three original papers, which surprisingly cover the same research topic, the development of virtual reality systems. The conception of fully interactive virtual reality systems is still a challenge. To choose the best interaction techniques and devices to each application task, to combine different technologies in a single system, to quickly prototype these systems, and to fulfill the expectations of the final user are just some few examples of problems that need to be faced by developers. The use of virtual reality and 3D interaction is yet new and there is not sufficient standards to follow in order to succeed. The first paper of this issue, “Visual Programming for Virtual Reality Applications Based on InTml”, was written by Pablo Figueroa, Santiago Gil, Raul Oses, Juan Toro, Catalina Rodriguez, Christian Benavides and Esteban Correa, from Colombia. The paper presents VPE, a visual programming environment developed to help in the development of portable virtual reality applications. More than this, the authors report advantages and drawbacks of their approach and share with us the lessons learned with this work. The paper “Assessment Systems for Training Based on Virtual Reality: A Comparison Study” authored by Ronei M. Moraes and Liliane S. Machado, from Brazil, discusses some of the challenges to construct a medical simulator based on virtual reality. An important question concerning the use of virtual reality based training is how to know when the user will be ready to practice in real situations. In this paper, the authors compared four methodologies for online assessment. The goal is to identify methods that could be used to reconfigure the simulation according to users’ performance in real time. I invite you to read the paper and make your own choices. The third and last paper, “Experiences with Virtual Learning Using 3D Interactive Systems for Education and Training”, was written by Damian Schofield, from USA, and is also related to virtual reality simulators. The author presents a virtual learning environment (ViRILE) developed by his group and uses it to highlight the complex operational problems that have been encountered during the process. In this paper, the lessons learned with the experience are extrapolated into general guidelines that are here shared with the readers. We hope this issue will fulfill your expectations. Enjoy it!

The use of augmented reality (AR) and virtual reality (VR) for life support training is increasing. These technologies provide an immersive experience that supports learning in a safe and controlled environment. This review focuses on the use of AR and VR for emergency care training for health care providers, medical students, and nonprofessionals. In particular, we analyzed (1) serious games, nonimmersive games, both single-player and multiplayer; (2) VR tools ranging from semi-immersive to immersive virtual and mixed reality; and (3) AR applications. All the toolkits have been investigated in terms of application goals (training, assessment, or both), simulated procedures, and skills. The main goal of this work is to summarize and organize the findings of studies coming from multiple research areas in order to make them accessible to all the professionals involved in medical simulation. The analysis of the state-of-the-art technologies reveals that tools and studies related to the multiplayer experience, haptic feedback, and evaluation of user’s manual skills in the foregoing health care-related environments are still limited and require further investigation. Also, there is an additional need to conduct studies aimed at assessing whether AR/VR-based systems are superior or, at the minimum, comparable to traditional training methods.

Introduction. The purpose of the present contribution is to perform a detailed anatomic and virtual reality three-dimensional stereoscopic study in order to test the effectiveness of the extended endoscopic endonasal approaches for selected anterior and posterior circulation aneurysms.Methods. The study was divided in two main steps: (1) simulation step, using a dedicated Virtual Reality System (Dextroscope, Volume Interactions); (2) dissection step, in which the feasibility to reach specific vascular territory via the nose was verified in the anatomical laboratory.Results. Good visualization and proximal and distal vascular control of the main midline anterior and posterior circulation territory were achieved during the simulation step as well as in the dissection step (anterior communicating complex, internal carotid, ophthalmic, superior hypophyseal, posterior cerebral and posterior communicating, basilar, superior cerebellar, anterior inferior cerebellar, vertebral, and posterior inferior cerebellar arteries).Conclusion. The present contribution is intended as strictly anatomic study in which we highlighted some specific anterior and posterior circulation aneurysms that can be reached via the nose. For clinical applications of these approaches, some relevant complications, mainly related to the endonasal route, such as proximal and distal vascular control, major arterial bleeding, postoperative cerebrospinal fluid leak, and olfactory disturbances must be considered.

PURPOSE Limited access to adequate cancer surgery training is one of the driving forces behind global inequities in surgical cancer care. Affordable virtual reality (VR) surgical training could enhance surgical skills in low- and middle-income settings, but most VR and augmented reality systems are too expensive and do not teach open surgical techniques commonly practiced in these contexts. New low-cost VR can offer skill development simulations relevant to these settings, but little is known about how knowledge is gained and applied by surgeons training and working in specific resource-constrained settings. This study addresses this gap, exploring gynecologic oncology trainee learning and user experience using a low-cost VR simulator to learn to perform an open radical abdominal hysterectomy in Lusaka, Zambia. METHODS Eleven surgical trainees rotating through the gynecologic oncology service were sequentially recruited from the University Teaching Hospital in Lusaka to participate in a study evaluating a VR radical abdominal hysterectomy training designed to replicate the experience in a Zambian hospital. Six participated in semi-structured interviews following the training. Interviews were analyzed using open and axial coding, informed by grounded theory. RESULTS Simulator participation increased participants' perception of their surgical knowledge, confidence, and skills. Participants believed their skills transferred to other related surgical procedures. Having clear goals and motivation to improve were described as factors that influenced success. CONCLUSION For cancer surgery trainees in lower-resourced settings learning medical and surgical skills, even for those with limited VR experience, low-cost VR simulators may enhance anatomical knowledge and confidence. The VR simulator reinforced anatomical and clinical knowledge acquired through other modalities. VR-enhanced learning may be particularly valuable when mentored learning opportunities are limited.

Wireless virtual reality integrated multidisciplinary technology, combined with related industries and fields, has changed the way of human-computer interaction and opened up a new field of user experience. In recent years, with the rapid improvement of computer technology and hardware conditions, interactive technology has developed rapidly. The existing wireless virtual reality interactive system is too single and cannot be used in multiple environments. The original system requires a large number of sensor equipment, the cost is high, and the traditional perception technology is too restrictive and cannot realize human-computer interaction more naturally. This paper proposes a dual intention perception algorithm based on the fusion of touch (obtained by experimental simulation equipment), hearing, and vision. The algorithm can perceive the user’s operation intention through the user’s natural behavior and can identify the user’s two intentions at the same time. This paper proposes a navigational interactive mode, which provides users with multimodal intelligent navigation through intelligent perception of user intent and experimental progress. We determine the impact model of the interactive system effect evaluation and analyze its effect evaluation strategy in depth and then further quantify the indicators under the four effect dimensions of information perception, artistic reflection, social entertainment, and aesthetic experience. A combination of qualitative and quantitative methods was used to carry out relevant research on effect evaluation, usability test, and questionnaire interview. The experimental results show that this interactive system has better entertainment effects than other forms of film and television animation, but still needs to pay attention to and strengthen the construction and embodiment of film and television animation content, as well as the optimization and perfection of the fault-tolerant mechanism in the design process.

The SBC Journal on Interactive Systems (JIS) has been integrated to the Brazilian academic community in the areas of Virtual and Augmented Reality since the beginning. Since 2010 JIS has published special issues with extended versions of selected papers from SVR - Symposium on Virtual and Augmented Reality, the premier conference in Brazil covering these areas. The year of 2015 could not be different. For the 6th year, I am glad to announce JIS special issue on SVR.This issue contains extended versions of four papers selected among the best full papers of SVR 2015 – XVII Symposium on Virtual and Augmented Reality. I would like to thank Judith Kelner and Eduardo Albuquerque for their dedication as guest editors in this special issue, and invite you to read their editorial in the following.We also have in this issue an original paper by Amyr Borges Fortes Neto, Soraia Raupp Musse, and Catherine Pelachaud, entitled “Emotion Contagion Model for Crowds”. In this paper, the authors use a computational model for emotion contagion process in the context of crowd simulation to create realistic perception of agent behaviors on crowds.I also would like to thank the authors and reviewers that contributed to this issue of JIS, and I hope it fulfills your expectations. JIS Editorial Board is looking forward to receiving your contributions in areas related to Virtual and Augmented Reality, Games, and/or Human-Computer Interaction.

The formation of safety-related competencies is a difficult task. These specific safety competencies, unlike other competencies, are difficult to fully develop by providing safety learners and students. Simulation Technologies could be the solution to make it easier for students to develop competencies related to human safety. In this thesis, the following methods were used: analysis of scientific literature, projective methods, mathematical methods – in particular registration and ranking, theoretical methods including: analysis, synthesis, generalization, comparison, conclusions, modeling, induction, deduction. The study showed that the use of simulation technologies allows creating conditions for the formation of the necessary competencies without increased risk for applicants and others. One of the most promising technologies for the formation of safety-related competencies is the use of virtual reality. The use of simulation technologies in the educational process will intensify it and improve the quality of education. Simulation technologies should take a special place in the training of specialists whose professional activities are associated with increased risk, as well as with significant negative consequences of erroneous decisions, in particular in the training of rescuers, military specialists, police, operators of complex systems (including transport, nuclear, etc.), medical workers, in the aerospace industry, etc.

Full textAbstract:
Due to the unique applications of virtual reality in many modern contexts, Second Life (SL) offers inimitable opportunities for research and exploration. A review of current research regarding SL has examined the influence of real world social influences in online interactions and what the effects on users may be. This suggests the importance of developing an understanding of the relationship between users’ real life and their Second Life, and how the two are related. Some research has begun to reveal the effectiveness of telecommunication and computer simulation with certain clients in the fields of mental health and social work, yet there is a lack of sufficient research done within the context of virtual worlds. The implications for social work intervention in virtual reality could solve persistent concerns with transportation, distance, access to services and education, however questions about the relevance of social work practice in SL and the potential for implementation must be answered.
