Effects of Virtual Reality Based Microteaching Training on Pre-Service Teachers’ Teaching Skills from a Multi-Dimensional Perspective

Virtual Reality (VR) shows the potential to tackle the limitations and deficiencies of traditional microteaching training by offering an intricate and lifelike environment that helps pre-service teachers to develop their teaching skills. However, the effects of VR training on each teaching skill sub-dimension remain inconclusive. This study identified nine sub-dimensions of teaching skills through a literature review. Moreover, a VR-based microteaching training system was developed, and the effects of VR on these sub-dimensions of teaching skills were explored by conducting a comparative experiment between virtual and traditional microteaching training. The results showed that virtual microteaching considerably enhanced pre-service teachers' teacher efficacy compared to traditional training, especially the efficacy of instructional strategies and classroom management. Furthermore, more significant improvements were noted in the questioning skill and the language and posture skills after virtual microteaching training, although there was no significant difference in teaching skills overall. Moreover, pre-service teachers reported a highly immersive experience during the virtual microteaching.

Configuration of a depth-fused 3D pyramid display for volumetric art

An increasingly indispensable facet of modern communication systems is the establishment of an immersive and lifelike environment that fosters authentic interactions among individuals with diverse vantage points. The cultivation of these organic interconnections finds its conduit in the integration of a depth-fused 3D (DFD) display, a pivotal mechanism for engendering a palpable sense of depth perception in objects. The evolutionary trajectory of the DFD concept aligns with the relentless pursuit of augmenting user engagement and satisfaction. In pursuit of advancing this paradigm, the present study embarks upon a meticulously designed experiment aimed at the calibration and optimization of a DFD pyramid display. The pivotal objective is to endow users with comprehensive presentation of 3D images from four discrete viewpoints, each separated by intervals of 90°. By configuring the intricate dimensions of the DFD pyramid display, this research endeavors to accentuate the potency of this technology, paving the way for an enriched and holistic visual encounter.

This research aims to develop an effective computer-based work-based learning (WBL) accounting e-module that enhances students' practical skills and their ability to apply accounting knowledge in real-world scenarios. The research followed a research and development approach, utilizing the Rowntree development model. Formative evaluation was conducted based on Tessmer & Martin's theory. The study consisted of stages including analysis of teaching materials, tailored e-module development, prototype creation (paper-based and computer-based), expert evaluation, and field testing. The developed accounting e-module successfully simulates real workplace situations through interactive exercises, case studies, and simulations. Expert evaluation confirmed the suitability of the learning media. Field testing, encompassing various settings, revealed increased student engagement, motivation, and improved learning outcomes. This research led to the creation of a robust work-based learning (WBL) accounting computer e-module. The module effectively bridges theoretical learning with practical application, enhancing students' skills and performance in the field of accounting. The findings affirm the viability and effectiveness of the developed e-module as a valuable pedagogical tool.

Hypnosis associated with 3D immersive virtual reality technology during bronchoscopy under local anesthesia.

BackgroundPatients undergoing flexible bronchoscopy under local anesthesia usually experience anxiety before and during the procedure. Different non-pharmacological techniques, including music and hypnosis, are used to distract patients’ attention, and to reduce anxiety. The new technique “virtual reality hypnosis (VRH)”, defined as a hypnotic induction suggestion delivered by personalized virtual reality software, can generate a simulation of a lifelike environment. No study has described the use of VRH during bronchoscopy. The objective is to investigate the anxiety reducing effect and the satisfaction of patients, physicians, and nurses using VRH during bronchoscopy.MethodsVRH was proposed to all patients who experienced anxiety before undergoing flexible bronchoscopy under local anesthesia. Local anesthesia was performed using 5% lidocaine spray only. No sedation was used. After the procedure, patients, physicians and nurses filled a standardized satisfaction form.ResultsTwenty consecutive patients who reported pre-procedure anxiety were included. The sex ratio was 16 women/4 men, the median age was 65 years. Eight patients (40%) had undergone a previous bronchoscopy under local anesthesia. The median duration of the procedure was 10 minutes, and all procedures were completed. The median level of anxiety of patients decreased from 9/10 before the procedure to 4/10 during the procedure. The median satisfaction rate regarding the use of VRH was 10/10. All patients agreed to use VRH again in case of a new bronchoscopy procedure.ConclusionsThis preliminary report has shown that VRH was useful to reduce patients’ anxiety during bronchoscopy under local anesthesia. VRH was easily implemented in the routine practice.

Novel medication safety training module.

Escape rooms are effective educational tools for engaging learners and may serve as a strategy for medication safety training to increase perceived learned safety measures and knowledge retention. Escape rooms are lifelike environments in which participants work together to solve a succession of puzzles to escape a locked room in the allotted time. Novel medication safety training modules such as a pharmacy escape room allow medical errors to be simulated in a team-based, controlled environment focusing on system improvement to establish a culture of safety. This project was conducted to improve medication safety knowledge using a novel pharmacy escape room training module piloted within a large, integrated pharmacy department. Several pilot groups of 2 or more pharmacy employees took part in a virtual medication safety escape room as part of a training module at Advocate Aurora Health between January and March 2021. Participants included pharmacists and pharmacy technicians employed at Aurora St. Luke's Medical Center, Aurora Sinai Medical Center, and Pharmacy Integrated Clinical Services. Assessments were administered before and after completion of the escape room module to evaluate medication safety knowledge and perceived learned safety measures by comparing scores. A total of 101 employees participated in the pharmacy escape room, with an average escape time of 42 minutes. Overall assessment scores before completion of the escape room module ranged from 20% to 86.6%, while those afterwards ranged from 33.3% to 93.3%. Participant feedback was positive, with reports that the novel escape room training module was more engaging and interactive than the alternative online self-paced learning modules. Virtual escape rooms can be used as a novel medication safety training module to increase medication safety knowledge and allow medical errors to be simulated in a controlled environment. Incorporating high-reliability tools and tactics into development of the escape room can promote safe medication practices and reinforce principles of high-reliability organizations.

An overview of applying virtual reality intervention to improve functional outcomes for post-stroke patients in rehabilitation

Post-stroke patients may have to experience a wide range of impairments or deficits such as movement dysfunction or cognitive impairments that require early rehabilitation management to get better recovery. The rapid development in technology facilitates for many aspects in medicine and rehabilitation. In recent years, virtual reality intervention has been a novel therapy improving functional outcomes among post-stroke patients (Lee, Park, & Park, 2019). Specifically, virtual reality technology has created a life-like environment to stimulate physical activities that may encourage stroke survivors to take part in activities willingly through interaction in virtual environment which is quite similar with the real world (Kizony, Levin, Hughey, Perez, & Fung, 2010). This overview is going to analyse the effectiveness of virtual reality intervention in improving functional outcomes for post-stroke patients and give some recommendations in clinical practice.

A-016 The Relationship between Visual Memory and Performance in Virtual Reality Among Older Adults

Abstract Objective Over the past fifty years, many traditional paper-and-pencil neuropsychological tests have been translated to new computerized devices (Canini et al., 2014). Virtual reality offers neuropsychologists an opportunity to observe patients’ neurocognitive functioning in an immersive, lifelike environment, rich in visual stimuli (Morganti, 2004), yet relatively little is known about the relationship between visual memory and performance on learning and memory tasks in virtual reality environments. The purpose of this study was to investigate, among older adults, the relationship between visual memory, as measured by a traditional paper-and-pencil test, and procedural learning and memory performance in a virtual reality environment simulating meal preparation tasks. Methods Older adults (N = 73) ages 55-90 (M = 72.77, SD = 7.87) were administered the Weschler Adult Intelligence Scale-Fourth Edition (WMS-IV) Visual Reproduction Immediate Recall and the Virtual Kitchen Protocol (VPK), a virtual reality-based measure of learning and memory for meal preparation tasks. Results Participants performance on the immediate portion of WMS-IV, visual reproduction, correlated with their performance on the VPK teaching trial (r = .65, p = 0.01), immediate recall (r = .51, p = 0.01), delayed recall (r = .58, p = 0.01), and forced choice recognition ( r = ..54, p = 0.01) of Job Sim. Conclusion Results suggest that visual memory aids healthy older adults in procedural learning and memory tasks in the Virtual Kitchen Protocol, a virtual reality environment simulating meal preparation tasks. These results suggest that visual memory ability is germane to performance in virtual reality environments that are rich in visual stimuli.

Dynamic Bioinks to Advance Bioprinting.

The development of bioinks for bioprinting of cell-laden constructs remains a challenge for tissue engineering, despite vigorous investigation. Hydrogels to be used as bioinks must fulfill a demanding list of requirements, mainly focused around printability and cell function. Recent advances in the use of supramolecular and dynamic covalent chemistry (DCvC) provide paths forward to develop bioinks. These dynamic hydrogels enable tailorability, higher printing performance, and the creation of more life-like environments for ultimate tissue maturation. This review focuses on the exploration and benefits of dynamically cross-linked bioinks for bioprinting, highlighting recent advances, benefits, and challenges in this emerging area. By incorporating internal dynamics, many benefits can be imparted to the material, providing design elements for next generation bioinks.

Hand Gesture-Based Virtual Reality Training Simulator for Collaboration Rescue of a Railway Accident

Abstract Training simulator is an efficient and innovative tool to help users learn professional skills due to its convenience and safety. However, complex human–computer interaction is one of the main disadvantages that limit its effectiveness in safety training, especially for the rescue of a railway accident that requires collaborations. Through designing a set of task-specific hand gestures, we developed a training simulator for the recovery of a railway accident that helps the rescuers learn and practice rescue skills in a life-like environment and gain the firsthand experience. To test the validity of our training simulator, a user experiment is designed to compare it with the controller-based simulator in a between-groups study with 51 participants, focusing on different aspects of effectiveness. The results demonstrate that the hand gesture-based controller can be more efficient and usable to deal with complex interactions than the traditional hand-held controller.

A New Methodology for Use by a Single Caregiver to Bathe Bedridden Elderly Persons Using Advanced Mechatronic Systems.

In the framework of this paper, we aimed to propose a methodology for giving baths to elderly, bedridden persons, when this task is performed by a single caregiver. Usually, two caregivers are required for nursing a bedridden patient, especially when certain important tasks are needed (e.g., bathing the patient), but this is not always possible. The entire study considers the primary user’s perspective—the caregiver—who is responsible for a wide range of tasks; thus, suffering physical and psychological exhaustion over time. A physical prototype has been developed for allowing caregivers to perform tests in a life-like environment, by means of the device and the methodology. This technology, therefore, will represent an important contribution to the quality of life of caregivers. Considering an increase in the share of the elderly population and the related problems that arise in daily care, this project intends to be beneficial contemporarily. The presented methodology has been successfully tested and validated.

Robotics in Health Care: Perspectives of Robot-Aided Interventions in Clinical Practice for Rehabilitation of Upper Limbs

Robot-aided systems to support the physical rehabilitation of individuals with neurological impairment is one of the fields that has been widely developed in the last few decades. However, the adoption of these systems in clinical practice remains limited. In order to better understanding the causes of this limitation, a systematic review of robot-based systems focused on upper extremity rehabilitation is presented in this paper. A systematic search and review of related articles in the literature were conducted. The chosen works were analyzed according to the type of device, the data analysis capability, the therapy method, the human–robot interaction, the safety strategies, and the focus of treatment. As a conclusion, self-adaptation for personalizing the treatments, safeguarding and enhancing of patient–robot interaction towards training essential factors of movement generation into the same paradigm, or the use of lifelike environments in fully-immersive virtual reality for increasing the assimilation of motor gains could be relevant factors to develop more accepted robot-aided systems in clinical practice.

Trapped as a Group, Escape as a Team: Applying Gamification to Incorporate Team-building Skills Through an 'Escape Room' Experience.

Teamwork, a skill critical for quality patient care, is recognized as a core competency by the Accreditation Council for Graduate Medical Education (ACGME). To date, there is no consensus on how to effectively teach these skills in a forum that engages learners, immerses members in life-like activities, and builds both trust and rapport. Recreational ‘Escape Rooms’ have gained popularity in creating a life-like environment that rewards players for working together, solving puzzles, and completing successions of mind-bending tasks in order to effectively ‘escape the room’ in the time allotted. In this regard, escape rooms share many parallels with the multitasking and teamwork that is essential for a successful emergency department (ED) shift.A pilot group of nine emergency medicine (EM) residents and one senior EM faculty member underwent a commercial escape room as part of a team-building exercise in January 2018. The escape room required participants to practice teamwork, communication, task delegation, and critical thinking to tackle waves of increasingly complex puzzles, ranging from hidden objects, physical object assembly (i.e., jigsaw puzzles), and symbol matching. Activities required members to recognize and utilize the collective experiences, skills, knowledge base, and physical abilities of the group. After the game, players underwent a structured ‘game-master’ debriefing facilitated by an employee of the commercial escape room; this was followed by a post-event survey facilitated by a faculty member, which focused on participants’ feelings, experiences, and problem-solving techniques.Escape rooms afford learners the opportunity to engage in an activity that rewards teamwork and effective leadership through experiences that directly link to specific ACGME milestones and educational learning theories. EM participants were engaged in the activity and felt that the escape room reproduced an environment analogous to the ED. The debriefing that followed the activity provided a satisfactory conclusion to the experience; but learners preferred a more organized debriefing format that provided them with constructive and specific feedback on their performance.

Contagion of Cheating Behaviors in Online Social Networks

Human behaviors are known to spread through social contact. The diffusion process on social networks has also been leveraged to understand the spread of undesirable contagion. The contagion of malicious or even criminal behaviors in online social networks is just beginning to attract attention. Here, we study the social contagion problem of cheating behavior found in the massively multiplayer online role-playing game (MMORPG) that provides a lifelike environment with rich and realistic user interactions. Because cheating users boast an abnormal thus conspicuous degree of success, it has a strong chance of being noticed by their friends and leading them to cheat themselves. To detect and prevent cheating, it is beneficial to understand this dynamic as a contagion problem. In this paper, we show the existence of the contagion of cheating. We then explore various possible social reinforcement mechanisms after introducing several factors to quantify the effect of social reinforcement on the contagion and analyze the dynamics of bot diffusion in an extensive user interaction log from a major MMORPG.

Qu’apportent les outils de réalité virtuelle en psychiatrie de l’enfant et l’adolescent ?

Virtual reality is a relatively new technology that enables individuals to immerse themselves in a virtual world. It offers several advantages including a more realistic, lifelike environment that may allow subjects to “forget” they are being assessed, allow a better participation and an increased generalization of learning. Moreover, the virtual reality system can provide multimodal stimuli, such as visual and auditory stimuli, and can also be used to evaluate the patient's multimodal integration and to aid rehabilitation of cognitive abilities. The use of virtual reality to treat various psychiatric disorders in adults (phobic anxiety disorders, post-traumatic stress disorder, eating disorders, addictions…) and its efficacy is supported by numerous studies. Similar research for children and adolescents is lagging behind. This may be particularly beneficial to children who often show great interest and considerable success on computer, console or videogame tasks. This article will expose the main studies that have used virtual reality with children and adolescents suffering from psychiatric disorders. The use of virtual reality to treat anxiety disorders in adults is gaining popularity and its efficacy is supported by various studies. Most of the studies attest to the significant efficacy of the virtual reality exposure therapy (or in virtuo exposure). In children, studies have covered arachnophobia social anxiety and school refusal phobia. Despite the limited number of studies, results are very encouraging for treatment in anxiety disorders. Several studies have reported the clinical use of virtual reality technology for children and adolescents with autistic spectrum disorders (ASD). Extensive research has proven the efficiency of technologies as support tools for therapy. Researches are found to be focused on communication and on learning and social imitation skills. Virtual reality is also well accepted by subjects with ASD. The virtual environment offers the opportunity to administer controlled tasks such as the typical neuropsychological tools, but in an environment much more like a standard classroom. The virtual reality classroom offers several advantages compared to classical tools such as more realistic and lifelike environment but also records various measures in standardized conditions. Most of the studies using a virtual classroom have found that children with Attention Deficit/Hyperactivity Disorder make significantly fewer correct hits and more commission errors compared with controls. The virtual classroom has proven to be a good clinical tool for evaluation of attention in ADHD. For eating disorders, cognitive behavioural therapy (CBT) program enhanced by a body image specific component using virtual reality techniques was shown to be more efficient than cognitive behavioural therapy alone. The body image-specific component using virtual reality techniques boots efficiency and accelerates the CBT change process for eating disorders. Virtual reality is a relatively new technology and its application in child and adolescent psychiatry is recent. However, this technique is still in its infancy and much work is needed including controlled trials before it can be introduced in routine clinical use. Virtual reality interventions should also investigate how newly acquired skills are transferred to the real world. At present virtual reality can be considered a useful tool in evaluation and treatment for child and adolescent disorders.

What Virtual Reality Research in Addictions Can Tell Us about the Future of Obesity Assessment and Treatment

Virtual reality (VR), a system of human-computer interaction that allows researchers and clinicians to immerse people in virtual worlds, is gaining considerable traction as a research, education, and treatment tool. Virtual reality has been used successfully to treat anxiety disorders such as fear of flying and post-traumatic stress disorder, as an aid in stroke rehabilitation, and as a behavior modification aid in the treatment of attention deficit disorder. Virtual reality has also been employed in research on addictive disorders. Given the strong evidence that drug-dependent people are highly prone to use and relapse in the presence of environmental stimuli associated with drug use, VR is an ideal platform from which to study this relationship. Research using VR has shown that drug-dependent people react with strong craving to specific cues (e.g., cigarette packs, liquor bottles) as well as environments or settings (e.g., bar, party) associated with drug use. Virtual reality has also been used to enhance learning and generalization of relapse prevention skills in smokers by reinforcing these skills in lifelike environments. Obesity researchers and treatment professionals, building on the lessons learned from VR research in substance abuse, have the opportunity to adapt these methods for investigating their own research and treatment questions. Virtual reality is ideally suited to investigate the link between food cues and environmental settings with eating behaviors and self-report of hunger. In addition, VR can be used as a treatment tool for enhancing behavior modification goals to support healthy eating habits by reinforcing these goals in life-like situations.

Exploring Possibilities: Virtual Reality in Nursing Research

This article describes the use of virtual reality (VR) as a method of measurement in nursing research. Virtual reality refers to the use of computerized displays to show a lifelike environment in which the user interacts. Although many disciplines are beginning to use VR environments in research, nursing has yet to embrace this technology. Nursing, as a profession that values the interaction between the environment, individual, and health, can benefit from the use of VR in research. Establishing reliability and validity of the VR tool selected for research is important and requires special consideration. Virtual reality testing can produce side effects, such as vertigo and discomfort, which must be anticipated in the research protocol.

The Future of Automotive Design & amp; Development: 3D for All

For over 20 years, automotive manufacturers have been harnessing the power of 3D to help create, optimize and produce great vehicles. Product Lifecycle Management (PLM) capabilities such as concurrent development, seamless integration, simultaneous engineering, single source database, and real-time visibility have long been capable within the automotive development process. However, the reality is that these tools have existed for a select few within a corporation, and have never been pervasive to every person involved in a product’s development process. Today, there are certain market drivers requiring more from PLM technology. This includes the fact that companies must drive innovation to survive in today’s increasingly competitive and global auto industry. The next generation of 3D PLM tools, referred to as PLM 2.0 can bring real-time, global collaboration to life with features such as a single PLM platform for Intellectual Property (IP) management (one database and one server), and the open Server-Oriented Architecture (SOA) development platform. With only a web connection, product authoring and collaboration are enabled for real time, concurrent work, across multiple remote locations all in a 3D lifelike environment. This presentation will point out how by expanding 3D PLM beyond engineering and manufacturing to include everyone who has a role in the life of a vehicle from business users to end consumers, vehicles will be developed in a shorter time frame, and better-suited to the public desires, with improvements made along the whole product development process.

Can You Hear What I See? Nonverbal Communication and the Changing Face of TML

Business training and education are changing. Organizations have experienced dramatic changes in their structure, competitive environment, and the demographics and demands of their employees. As a result, organizations are seeking new and innovative ways to train employees. At the same time the evolution of technology mediated learning tools (TML) has resulted in flexible, interactive, engaging, learning technology tools that promote experiential learning, analytical thinking and problem solving. Simulation based technology mediated learning (SimTML) tools are gaining popularity in practice. SimTML facilitates lifelike environments that utilize animated pedagogical agents (APAs) which employ nonverbal communication traits in their interaction with the user. The effect is a lifelike, face-to-face interaction, between the user and the APA. The result is a flexible, interactive, engaging, TML tool that promotes experiential learning, analytical thinking and problem solving. This paper explores current SimTML technology, how we interact with learning technology, and provides selection and evaluation principles for organizations to use when evaluating SimTML tools for their own training programs.
