Abstract Background New approaches to e-learning and the use of virtual reality technology and serious game in medical education are on the rise. Therefore, the purpose of this study was to compare the effectiveness of lecture method and virtual reality-based serious gaming (VRBSG) method on students learning outcomes about the approach to coma. Methods We adopted a randomized trial method for this study and selected 50 medical students dividing them into experimental and control groups. Students’ learning outcome was measured with a 10-item test. Serious game usability scale was used to evaluate the usability of the serious game. Descriptive and inferential statistics were used for data analysis by SPSS-22 software. Results Students’ familiarity with e-learning and VRBSG was low. The mean usability of a VRBSG was 126.78 ± 10.34 out of 150. The majority of students were eager to be instructed through VRBSG. The mean score of learning outcomes in the experimental group was significantly higher than the control group (t = − 2.457, P = 0.019). Conclusion Students’ learning outcomes in the VRBSG group in the test approach to coma were significantly better than the lecture group. The usability of the serious game instruction method was high. Taken together, instruction through VRBSG had an effective role in medical students’ learning.

Design And Application

Virtual reality (VR) systems are becoming increasingly affordable for the general population. These technologies have potentially beneficial applications in a wide variety of contexts. Primary considerations for enhancing VR experiences in these contexts are the level of immersion enabled by the technology and the level of presence experienced by the user. Older adults are often overlooked during the design and application of VR technologies, even though these types of systems may help overcome certain aspects of the age-related challenges and limitations that they experience. The purpose of this paper is to provide an overview of the applications of VR for older adults and to identify characteristics of older users that could impact the way they experience these advanced technologies. This review culminates in design recommendations for increasing the likelihood that the immersiveness of the VR system has its intended effect on the experience of virtual presence for older adults.

Visually Induced Motion Sickness (VIMS) is a bothersome and sometimes unsafe experience, frequently experienced in Virtual Reality (VR) environments. In this study, the effect of up to four training sessions to decrease VIMS in the VR environment to a minimal level was tested and verified through explicit declarations of all 14 healthy participants that were recruited in this study. Additionally, the Motion Sickness Assessment Questionnaire (MSAQ) was used at the end of each training session to measure responses to different aspects of VIMS. Total, gastrointestinal, and central motion sickness were shown to decrease significantly by the last training session, compared to the first one. After acclimatizing to motion sickness, participants’ sense of presence and the level of their motion sickness in the VR environment were assessed while actuating three novel and sophisticated VR systems. They performed up to four trials of the Illinois agility test in the VR systems and the real world, then completed MSAQ and Igroup Presence Questionnaire (IPQ) at the end of each session. Following acclimatization, the three VR systems generated relatively little motion sickness and high virtual presence scores, with no statistically meaningful difference among them for either MSAQ or IPQ. Also, it was shown that presence has a significant negative correlation with VIMS.

BACKGROUND History taking and physical examination (H&P) is an important core competency of undergraduate medical education. Recent advances in virtual reality (VR) simulation, lowering the complexity of learning tasks and the cognitive load of the learners, make this novel technology well suited for the initial training of novices. Reduced heart rate variation (HRV) is associated with decreased cognitive efficiency. Whether a 360° VR video review can impact learning outcome, cognitive load, and HRV while learning H&P skills in undergraduate medical students is unknown. OBJECTIVE We explored the effectiveness of 360° VR versus 2-dimensional (2D) video review to learn H&P skills with regards to learning outcome, cognitive load, and HRV. METHODS In 2018, we randomly assigned (1:1) 64 undergraduate medical students to either a 360° VR or 2D video group (matched by age, sex, and cognitive style) with allocation concealment to learn H&P skills using VR headsets and controllers. Subsequently, the participants each performed a focused H&P with a real outpatient. Two raters used the Mini-Clinical Evaluation Exercise (Mini-CEX) and Direct Observation of Procedural Skills (DOPS) questionnaires to assess the participants’ performance blindly. The Cognitive Load Component questionnaire and a portable electrocardiogram monitor were used to measure cognitive load and HRV, respectively. RESULTS All participants completed the study (mean age=24.2 years, standard deviation=0.9 years; 44 [69%] males and 20 [31%] females). The physical examination and student’s satisfaction scores (Mini-CEX), total DOPS score, total and intrinsic cognitive load scores, and standard deviation of normal to normal R-R intervals in the 360° VR video group were significantly higher than those in the 2D video group (effect size=0.63, 0.56, 0.72, 0.53, 0.67, and 0.52, respectively). Differences in the other aspects of the Mini-CEX and cognitive loads of both groups were not statistically significant. CONCLUSIONS This study provides a high level of evidence to confirm that 360° VR video review can help undergraduate medical students to perform fundamental H&P skills as effectively as traditional 2D video review. Furthermore, a 360° VR video review could be used to more efficiently examine the body of a real patient with higher learner’s satisfaction. These findings may inspire the design of 360° VR video-based training protocols to enhance competencies other than history taking.

The hip joint is highly prone to traumatic and degenerative pathologies resulting in irregular locomotion. Monitoring and treatment depend on high-end technology facilities requiring physician and patient co-location, thus limiting access to specialist monitoring and treatment for populations living in rural and remote locations. Telemedicine offers an alternative means of monitoring, negating the need for patient physical presence. In addition, emerging technologies, such as virtual reality (VR) and immersive technologies, offer potential future solutions through virtual presence, where the patient and health professional can meet in a virtual environment (a virtual clinic). To this end, a prototype asynchronous telemedicine VR gait analysis system was designed, aiming to transfer a full clinical facility within the patients’ local proximity. The proposed system employs cost-effective alternative motion capture combined with the system’s immersive 3D virtual gait analysis clinic. The user interface and the tools in the application offer health professionals asynchronous, objective, and subjective analyses. This paper investigates the requirements for the design of such a system and discusses preliminary comparative data of its performance evaluation against a high-fidelity gait analysis clinical application.

Set Up

The purpose of this study was to evaluate the applicability of virtual reality simulation after experience of dental caries diagnosis for dental students before exposing to clinical pediatric practice.A pediatric patient model of a five-year-old child with primary dentition was developed and a caries model that is amenable to VR(virtual reality) diagnosis was organized and set-up. The dental student’s were allowed to use the simulated model for fifteen minutes and their experiences were evaluated using a self-reported questionnaire to evaluate presence and usability of this application.Overall, virtual presence and appearance area of the simulation were highly scored. The result indicates that the VR model has no significant difference from the actual clinical caries regardless of grade of students, gender and VR experience. If the prototype is continuously advanced, its applicability in dental education will increase.
