文摘Objectives:To explore the efficacy and safety of virtual reality(VR)in relieving negative emotions in patients with breast cancer with different personalities.Methods:A randomized controlled trial was conducted.Between April 2023 and October 2023,we enrolled patients with breast cancer treated in the Department of Breast Cancer and Oncology at Sun Yat-Sen Memorial Hospital,Sun Yat-Sen University,Guangdong Province.The patients were randomly divided into an intervention group(n=118)and a control group(n=119)using block randomization.The intervention group received the VR intervention 3-5 times over 5±2 weeks using natural landscapes with music or relaxation guidance,and the duration of each VR intervention was 15±3 min.The control group received routine nursing care,including disease education and psychological counseling.Patients were assessed using the Type D Scale,Positive and Negative Affect Scale,and Distress Thermometer,and adverse events during the intervention were recorded.Results:Overall,85 patients completed the study(44 in the intervention group and 41 in the control group).Patients with Type D personalities showed more negative emotions[25.0(21.5,27.5)vs.19.0(16.0,24.0),P=0.001]and distressed attitudes[4.0(2.0,5.0)vs.3.0(1.0,4.0),P=0.020]with fewer positive emotions(27.2±5.6 vs.31.0±5.9,P=0.014)than those with non-Type D personalities.Total population analysis revealed no significant differences between the groups.However,in the subgroup analysis,patients with Type D personalities in the intervention group showed greater relief from negative emotions than those in the control group[median difference,-5.0(-9.0,-2.5)vs.-2.0(-4.0,2.0),P=0.046].No significant differences were found between groups of patients with non-Type D personality traits.The proportion of adverse events was not significantly different between groups(P=0.110).Conclusions:Breast cancer patients with Type D personalities suffer more severe negative emotions and distress,and more attention should be paid to them.VR intervention significantly and safely reduced negative emotions in patients with Type D personalities.
文摘This research pioneers the integration of geographic information systems(GIS)and 3D modeling within a virtual reality(VR)framework to assess the viability and planning of a 20 MW hybrid wind-solarphotovoltaic(PV)system connected to the local grid.The study focuses on Dakhla,Morocco,a region with vast untapped renewable energy potential.By leveraging GIS,we are innovatively analyzing geographical and environmental factors that influence optimal site selection and system design.The incorporation of VR technologies offers an unprecedented level of realism and immersion,allowing stakeholders to virtually experience the project's impact and design in a dynamic,interactive environment.This novel methodology includes extensive data collection,advanced modeling,and simulations,ensuring that the hybrid system is precisely tailored to the unique climatic and environmental conditions of Dakhla.Our analysis reveals that the region possesses a photovoltaic solar potential of approximately2400 k Wh/m^(2) per year,with an average annual wind power density of about 434 W/m^(2) at an 80-meter hub height.Productivity simulations indicate that the 20 MW hybrid system could generate approximately 60 GWh of energy per year and 1369 GWh over its 25-year lifespan.To validate these findings,we employed the System Advisor Model(SAM)software and the Global Solar Photovoltaic Atlas platform.This comprehensive and interdisciplinary approach not only provides a robust assessment of the system's feasibility but also offers valuable insights into its potential socio-economic and environmental impact.
文摘The use of virtual reality to educate preoperative patients has a positive impact on nurses as well as patients undergoing treatment.It can help improve patient satisfaction and improve favorable outcomes by reducing patient anxiety and proving adequate knowledge about the procedure and possible outcomes to the patient.It also reduces burden on nursing staff and counsellors.Larger and more diverse cohort studies will help us understand the wider application of this tool on the patient population.It may be difficult to apply this tool on elderly patients with failing eyesight,multiple physical comorbidities.Also,there may be reduced acceptance of this modality by older nursing staff and practitioners who may prefer the traditional verbal version for counselling.We will benefit from a combined approach of using virtual reality apps with tradition one-on-one counselling to help alleviate patient concerns and improve patient and healthcare professional satisfaction.

文摘Objectives:Emotional stress is a significant public health challenge.Virtual reality(VR)offers the potential for aiding emotional recovery.This study explores the impact of VR environment design factors on emotional recovery,examining underlying mechanisms through physiological indicators and behavioral responses.Methods:Two experimentswere conducted.Experiment 1 employed a 4[Scene Type:real environment(RE),virtual scenes that restore the RE(VR),virtual scenes that incorporate natural window view design(VR-W),and a no-scene control condition(CTL)]×3(Experimental Phase:baseline,emotion arousal,recovery)mixed design(N=33).Participants viewed a 4-min anxiety-inducing video followed by a 3-min scene exposure.State-Trait Anxiety Inventory-State Form(STAIS),galvanic skin response(GSR),and blood-volume pulse(BVP)frequency were analyzed with linear mixed-effects models.Experiment 2 used a 3(Motion-control mode:Unnatural,Semi-natural,Natural)×2(Sound form:Spatial positioning,Surround)×3(Experimental Phase:baseline,emotion arousal,recovery)mixed design(N=42).Presence was analyzed with the Scheirer–Ray–Hare test;phase efficacy was verified with Friedman tests.Results:Experiment 1 showed significant Scene Type×Experimental Phase interactions for GSR(F=8.006,p<0.001,η^(2)_(p)=0.624)and BVP frequency(F=11.491,p<0.001,η^(2)_(p)=0.704).VR-Wproduced the largest recovery(ΔGSR=–1.26;ΔBVP=–5.80;Hedges g≥0.83)vs.RE and VR.STAI-S returned to baseline across all Scene Types.Experiment 2 revealedmain effects of Motion-control mode(F=8.55,p=0.001,η^(2)_(p)=0.32)and Sound form(F=4.35,p=0.044,η^(2)_(p)=0.11)on Presence(Semi-natural+Spatial positioning highest).The greatest physiological recovery occurred with the UnnaturalMotioncontrolmode(GSRH=20.17,p<0.001,ε^(2)=0.49;BVPH=7.92,p=0.019),amplified by Spatial positioning Sound form only in this mode.Design factors did not influence STAI-S change.Conclusions:VR scenes are as restorative as RE;embedding VR-W accelerates recovery.Maximal Presence is not essential:Unnatural Motion-control mode induced the largest physiological recovery,especially combined with Spatial positioning Sound form.

文摘This manuscript critically evaluates the randomized controlled trial(RCT)conducted by Phiri et al,which assessed the effectiveness of virtual reality(VR)training for psychiatric staff in reducing restrictive practices(RPs).Specifically,this RCT investigated the impact of VR on the handling of aggressive patients by psychiatric staff compared to traditional training methods.Despite significant reductions in perceived discrimination in the VR group,there were no major improvements in self-efficacy or anxiety levels.The system usability scale rated the VR platform highly,but it did not consistently outperform traditional training methods.Indeed,the study shows the potential for VR to reduce RPs,although fluctuations in RP rates suggest that external factors,such as staff turnover,influenced the outcomes.This manuscript evaluates the study’s methodology,results,and broader implications for mental health training.Additionally,it highlights the need for more comprehensive research to establish VR as a standard tool for psychiatric staff education,focusing on patient care outcomes and real-world applicability.Finally,this study explores future research di-rections,technological improvements,and the potential impact of policies that could enhance the integration of VR in clinical training.

文摘Virtual reality(VR)is regarded as the next-generation display platform for immersive human-computer interaction.To solve the long-existing problem of vergence accommodation conflict in VR,varifocal displays based on the diffractive Pancharatnam–Berry lens(PBL)are considered as one of the most promising approaches with great compatibility to current display architectures.However,the diffractive nature of PBL leads to serious chromatic aberrations in optical systems,which deteriorates the image quality and discourages its actual usage.
文摘Background Exploring how immersive technologies can simulate and assess user experiences in designed environments is an important topic in architectural research.In this study,a multisensory virtual reality(VR)system developed to support the study of human-built environment interactions under multimodal conditions(visual,olfactory,and auditory)was evaluated.Methods The effectiveness of the system was tested by conducting in-depth user studies using a mixed-method approach to provide quantitative and qualitative evidence.The results of the case study were discussed,key features of the proposed prototype were assessed,and limitations and opportunities for future studies were identified.Results Findings showed that multisensory elements can deepen participants’sense of presence,increase engagement levels,and enrich overall user experience in immersive environments.Integrating olfactory stimuli into virtual representations of architectural spaces revealed how multisensory feedback informs spatial perception and supports the development of more responsive and human-centered design strategies.Conclusions This study contributes to the emerging field of sensory architecture,aiming to move beyond visual simulation toward a richer embodied understanding of space.The proposed approach provides valuable insights into the development of multisensory VR environments in architecture,enabling future research and immersive research methodologies in wider fields.
文摘Background:While traditional meditation practices are known for their mental health benefits,they often face limitations such as restricted access and environmental distractions.To address these challenges and enhance meditation effectiveness,this study implemented an immersive virtual reality meditation(IVRM)program and examined its potentialmental health benefits among university students-a population that frequently experiences significant psychological distress.Methods:Nineteen university students participated in eight 15-min sessions of an IVRM program designed to promote mindfulness and relaxation over the course of one month.Perceived stress and anxiety levels were assessed using validated self-report measures at baseline(T1)and post-intervention(T2).Twotailed paired t-tests were conducted to evaluate the preliminary efficacy of the program,and effect sizes were reported using Cohen’s d.Results:Significant reductions were observed from pre-to post-intervention in perceived stress(t(18)=3.694,p<0.001,SE=0.17,d=−0.85)and perceived anxiety(t(18)=5.113,p<0.01,SE=0.10,d=−1.20),both indicating large effect sizes.Conclusion:Our findings provide preliminary evidence that the IVRMprogramcan reduce stress and anxiety levels in university students.The positive results suggest that IVRM has the potential to serve as a novel,technology-based meditation intervention for individuals at elevated risk for developingmental health disorders.Furthermore,our study suggests important implications for future research.

文摘In the realm of virtual reality(VR),haptic feedback is integral to enhance the immersive experience;yet,existing wearable devices predominantly rely on skin contact feedback,lacking options for compact and non-contact breeze-sense feedback.Herein,we propose a compact and non-contact working model piezoelectret actuator for providing a gentle and safe breeze sensation.This easy-fabricated and flexible breeze-sense generator with thickness around 1 mm generates air flow pressure up to~163 Pa,which is significantly sensed by human skin.In a typical demonstration,the breeze-sense generators array showcases its versatility by employing multiple coded modes for non-contact information transmitting.The thin thinness and good flexibility facilitate seamless integration with wearable VR setups,and the wearable arrays empower volunteers to precisely perceive the continuous and sudden breeze senses in the virtual environments.This work is expected to inspire developing new haptic feedback devices that play pivotal roles in human-machine interfaces for VR applications.

文摘Objective:We aimed to perform a systematic review and meta-analysis to assess the efficacy of virtual reality(VR)distraction technologies in managing pain and anxiety in patients undergoing cystoscopy procedures.Methods:We searched PubMed,Embase,and the Cochrane Central Register of Controlled Trials from inception to July 2024,for studies comparing the use of VR distraction technologies versus no VR distraction in patients undergoing cystoscopy.The primary endpoints evaluated were patient-reported anxiety and procedural pain scores,and post-procedural heart rate(HR).Standardized mean differences(SMDs)and their 95%confidence intervals(CIs)were computed with the use of a random-effects model.The statistical analysis was conducted using Review Manager 5.4.Results:A total of 575 patients from four randomized controlled trials were included,of whom 289(50%)underwent the cystoscopy procedure using VR distraction technologies.The mean age of all patients was 57.25 years old,and 395(69%)of them were male.In our pooled analysis,we did not observe a statistically significant reduction in patient-reported procedural pain(SMD=0.16;95%CI=0.32-0.00;p=0.060;I^(2)=0%),anxiety(SMD=0.37;95%CI=1.65-0.90;p=0.6;I^(2)=93%),or post-procedural HR(SMD=0.58;95%CI=1.62-0.45;p=0.3;I^(2)=97%).Conclusion:In this comprehensive meta-analysis comprising 575 patients who underwent cystoscopy,the use of VR was not associated with a significant difference in pain,anxiety,or HR levels.
文摘The present paper addresses two issues pertaining to the use of virtual reality(VR).One issue pertains to the equipment utilized.VR technology can be classified into two main categories:Immersive and non-immersive.The immersive type of technology necessitates the use of substantial equipment,yet it is demonstrably efficacious.Furthermore,the efficacy of this approach is enhanced when combined with relaxation and biofeedback techniques.The other issue is that the efficacy of this approach is diminished when applied to chronic pain,in comparison to acute pain.The relief of chronic pain is a challenging endeavor due to the diminished functionality of the medial prefrontal cortex(mPFC)within the default mode network.Given the close relationship between the mPFC and the reward system dopamine,it is essential to develop a program that activates the reward system dopamine through the use of VR technology.
