As such, doctors should be competent and comfortable in performing the technique by themselves; however, they need to be adequately trained. The best method to ensure practitioner proficiency is by optimizing teaching at an institutional level, thus, educating all future doctors in the procedure. However, the Coronavirus Disease 19 (COVID-19) pandemic caused significant disruption to hospital teaching for medical students which necessitated investigating the effectiveness of virtual reality (VR) as a platform to emulate hospital teaching of knee arthrocentesis. A workshop was conducted with 100 fourth year medical students divided into three Groups: A, B and C, each receiving a pre-reading online lecture. Group A was placed in an Objective Structured Clinical Examination (OSCE) station where they were assessed by a blinded orthopaedic surgeon using the OSCE assessment rubric. Group B undertook a hands-on practice station prior to assessment, while Group C received a VR video (courtesy of the University of Adelaide’s Health Simulation) in the form of VR headset or 360° surround immersion room and hands-on station followed by the OSCE. Upon completion of the workshop, students completed a questionnaire on their confidence with the procedure and the practicality of the VR station. OSCE scores were compared between Groups B and C to investigate the educational value of VR teaching. On average, students with VR headsets reported higher confidence with the procedure and were more inclined to undertake it on their own. Students in Group C who used the VR station prior to assessment scored higher than the non-VR Groups (Group A, 56%; Group B, 67%; Group C 83%). Students in Group A had statistically significant results on average compared to those in Group B (t(69) = 3.003, <i>p</i> = 0.003), as do students in Group B compared to Group C (t(62) = 5.400, <i>p</i> &lt; 0.001). Within Group C students who were given VR headsets scored higher than immersion room students. The VR headset was beneficial in providing students with a representation of how knee arthrocentesis may be conducted in the hospital setting. While VR will not replace conventional in-hospital teaching, given current technological limitations, it serves as an effective teaching aid for arthrocentesis and has many other potential applications for a wide scope of medicine and surgical training.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"12 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141742636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article proposes a training module characterized by an innovative approach: the possibility of practicing the diagnosis, planning, execution stages and the physical possibility of performing the execution stage on the radiological phantom of the abdominal cavity. The proposed approach was evaluated by designing a set of 4 exercises corresponding to the 3 phases mentioned. To the research group included 10 radiologists and 5 residents in the study. Based on 20 clinical cases of liver tumors subjected to percutaneous thermoablation, we developed assessment tasks evaluating four skill categories: head-mounted display (HMD), ultrasound (US)/computed tomography (CT) image fusion interpretation, tracking system use, and the ability to insert a needle<b>.</b> The results were presented using the Likert scale.

Furthermore, the majority of literature reviews in this domain seem to have predominantly focused on academic sources, overlooking industry insights. To address these points, the current research took an interdisciplinary literature review approach to examine QoE literature covering both academic and industry sources from diverse fields (i.e., psychology, ergonomics, user experience, communication science, and engineering). Based on this rich dataset, we created a QoE model that illustrated 252 factors grouped into four branches - user, system, context, and content. The main finding of this review emphasized the substantial gap in the current research landscape, where complex interactions among user, system, context, and content factors in VR are overlooked.

In this study, we investigate whether detailed visualizations of position and orientation deviations are helpful for AR-assisted manual precise manipulation of objects. We developed three AR instructions with different visualizations of deviations: the logical deviation baseline instruction, the precise numerical deviations-based instruction, and the intuitive color-mapped deviations-based instruction. All three instructions visualized the required directions for manipulation and the logical values of whether the object met the accuracy requirements. Additionally, the latter two instructions provided detailed visualizations of deviations through numerical text and color-mapping respectively. A user study was conducted with 18 participants to compare the three AR instructions. The results showed that there were no significant differences found in speed, accuracy, perceived ease-of-use, and perceived workload between the three AR instructions. We found that the visualizations of the required directions for manipulation and the logical values of whether the object met the accuracy requirements were sufficient to guide manual precise manipulation. The detailed visualizations of the real-time deviations could not improve the speed and accuracy of manual precise manipulation, and although they could improve the perceived ease-of-use and user experience, the effects were not significant.

The autonomy of robots is increasing, but critical cases like search and rescue missions must involve the possibility of human intervention for ethical reasons and safety. To achieve effective human–robot interaction, the operator needs to have a sense of agency (SoA) over the activities of the robot. One possible way to increase one's SoA in remote control could be the use of VR technology. The remote control situation has some important features, so indicators of SoA need to be reproduced there independently. In our study, participants controlled a mobile robot using either a monitor or a VR-headset as an output device. In both cases, active control was contrasted with passive observation of the robot's movement. In each trial, participants estimated the distance traveled by the robot—a putative implicit indicator of SoA. A significant difference between subjective distance estimates was found in the active and passive conditions with the monitor, but not in the active and passive conditions with VR. The effect obtained in the monitor conditions suggests that distance estimates can be used as an implicit indicator of SoA in robot remote control. We believe that the lack of difference between the active and passive conditions in VR was caused by motion sickness due to a mismatch of visual and vestibular sensory cues, leading to a weakened SoA.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"87 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141573939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were 1st-year medical students who engaged in an empathy training IVR educational intervention around a scenario depicting older adults struggling with social isolation. Jefferson Scale of Empathy (JSE) questionnaire was administered before and after the intervention to measure the change in empathy levels. Data were analyzed using a paired sample t-test on the pre-/post-test JSE empathy scores to assess the change in empathy scores. Nineteen qualitative semi structured interviews were conducted immediately after the IVR experience and follow-up interviews were conducted six months later.
