Large-Scale Indoor Visual-Geometric Multimodal Dataset and Benchmark for Novel View Synthesis.

The accurate reconstruction of indoor environments is crucial for applications in augmented reality, virtual reality, and robotics. However, existing indoor datasets are often limited in scale, lack ground truth point clouds, and provide insufficient viewpoints, which impedes the development of robust novel view synthesis (NVS) techniques. To address these limitations, we introduce a new large-scale indoor dataset that features diverse and challenging scenes, including basements and long corridors. This dataset offers panoramic image sequences for comprehensive coverage, high-resolution point clouds, meshes, and textures as ground truth, and a novel benchmark specifically designed to evaluate NVS algorithms in complex indoor environments. Our dataset and benchmark aim to advance indoor scene reconstruction and facilitate the creation of more effective NVS solutions for real-world applications.

The Impact of Virtual Reality Simulations on Social Work Education: A Qualitative Study

ABSTRACT The purpose of this qualitative study was to explore the potential of virtual reality (VR) simulations for use as an effective learning modality for social work education. At a public college in a large U.S. Northeastern city with a mostly self-identified non-White student body, 19 respondents, including five BA and seven MSW social work students, as well as seven graduated former MSW students, participated in one of three focus groups in which they shared their thoughts and feelings regarding two VR simulations they experienced. One of the VR applications concerned racism and the other homelessness. The study found that VR has the ability to be an immersive and immediate experience that arouses intense emotional reactions in participants, thereby enhancing their empathy toward the individuals portrayed in the simulations and increasing participants’ motivation to participate in social action. The respondents overwhelmingly expressed that VR should be integrated into social work education, but that the emotional intensity it engenders creates the need for careful pre-briefing and debriefing. Issues of physical discomfort for some participants during the simulations need to be addressed as well.

Compact binocular holographic near-eye 3D display system based on a liquid crystal polarization grating

Holographic technology is considered as one of the most ideal 3D display technologies and has significant potential in near-eye display. However, binocular holographic near-eye 3D display still faces challenges such as serious visual fatigue and complex system. Here, we propose a compact binocular holographic near-eye 3D display system based on a liquid crystal polarization grating (LCPG). Based on the LCPG, the reconstructed light can be deflected respectively to left and right viewing areas. The proposed system achieves binocular display with only one phase-only spatial light modulator used to load computer-generated hologram, which makes the binocular display system more compact. Simultaneously, the proposed system reduces mismatches in the images perceived by two eyes, thus achieving a better binocular display effect. Experimental results demonstrate the feasibility of the proposed binocular holographic near-eye 3D display system with dual viewing areas. Additionally, based on the time-division multiplexing method, dynamic binocular holographic near-eye display can be achieved. The proposed system has potential applications in holographic virtual reality and augmented reality display.

More than meets the eye: Augmented reality in surgical oncology.

In the field of surgical oncology, there has been a desire for innovative techniques to improve tumor visualization, resection, and patient outcomes. Augmented reality (AR) technology superimposes digital content onto the real-world environment, enhancing the user's experience by blending digital and physical elements. A thorough examination of AR technology in surgical oncology has yet to be performed. A scoping review of intraoperative AR in surgical oncology was conducted according to the guidelines and recommendations of The Preferred Reporting Items for Systematic Review and Meta-analyzes Extension for Scoping Reviews (PRISMA-ScR) framework. All original articles examining the use of intraoperative AR during surgical management of cancer were included. Exclusion criteria included virtual reality applications only, preoperative use only, fluorescence, AR not specific to surgical oncology, and study design (reviews, commentaries, abstracts). A total of 2735 articles were identified of which 83 were included. Most studies (52) were performed on animals or phantom models, while the remaining included patients. A total of 1112 intraoperative AR surgical cases were performed across the studies. The most common anatomic site was brain (20 articles), followed by liver (16), renal (9), and head and neck (8). AR was most often used for intraoperative navigation or anatomic visualization of tumors or critical structures but was also used to identify osteotomy or craniotomy planes. AR technology has been applied across the field of surgical oncology to aid in localization and resection of tumors.

Does Preoperative Virtual Reality Experience Enhance Implant Positioning Accuracy in Total Hip Arthroplasty?

Purpose Total hip arthroplasty (THA) requires precise implant positioning to ensure long-term success. Herein, we evaluated the effect of virtual reality (VR) on the surgical precision of THA, particularly when used by experienced surgeons. Methods In this single-center, prospective, case-control study, 34 patients who underwent primary THA performed by a single experienced surgeon were divided into the control (without VR simulation) and VR (with VR simulation) groups. Preoperative planning involved the creation of three-dimensional models from computed tomography scans using ZedHip® software (Lexi, Tokyo, Japan). The primary outcomes assessed included the accuracy of implant placement, operative time, and intraoperative blood loss. The secondary outcomes included postoperative hospital stay and in-hospital complications. Results A significant improvement in radiographic inclination (RI) was observed in the VR group as compared to controls. Other surgical parameters, such as radiographic anteversion, operation time, blood loss, and postoperative hospital stay, showed no significant differences between the groups. Discrepancies in planned versus actual implant sizes were notedbut were not significantly different between groups. Conclusion VR application in preoperative planning improved the RI accuracy in acetabular cup placement for THA, demonstrating its potential to enhance surgical precision for experienced surgeons. This study highlights the evolving role of VR, from a training tool to an integral part of advanced surgical planning in orthopedics.

A Machine Learning Approach to Classifying EEG Data Collected with or without Haptic Feedback during a Simulated Drilling Task.

Artificial Intelligence (AI), computer simulations, and virtual reality (VR) are increasingly becoming accessible tools that can be leveraged to implement training protocols and educational resources. Typical assessment tools related to sensory and neural processing associated with task performance in virtual environments often rely on self-reported surveys, unlike electroencephalography (EEG), which is often used to compare the effects of different types of sensory feedback (e.g., auditory, visual, and haptic) in simulation environments in an objective manner. However, it can be challenging to know which aspects of the EEG signal represent the impact of different types of sensory feedback on neural processing. Machine learning approaches offer a promising direction for identifying EEG signal features that differentiate the impact of different types of sensory feedback during simulation training. For the current study, machine learning techniques were applied to differentiate neural circuitry associated with haptic and non-haptic feedback in a simulated drilling task. Nine EEG channels were selected and analyzed, extracting different time-domain, frequency-domain, and nonlinear features, where 360 features were tested (40 features per channel). A feature selection stage identified the most relevant features, including the Hurst exponent of 13-21 Hz, kurtosis of 21-30 Hz, power spectral density of 21-30 Hz, variance of 21-30 Hz, and spectral entropy of 13-21 Hz. Using those five features, trials with haptic feedback were correctly identified from those without haptic feedback with an accuracy exceeding 90%, increasing to 99% when using 10 features. These results show promise for the future application of machine learning approaches to predict the impact of haptic feedback on neural processing during VR protocols involving drilling tasks, which can inform future applications of VR and simulation for occupational skill acquisition.

Changes of oxidative stress in 3D film to be prepared for echocardiography: A randomized controlled study.

Echocardiography (ECHO) is a nonprocedure that causes acute stress in children. Fear, anxiety, and fluctuations in children's blood pressure and heart rate can potentially lead to alterations in echocardiographic measurements. The insufficient research on virtual reality pediatric preparation applications, particularly in the context of echocardiographic procedures, underscores the necessity for additional studies focusing on pediatric patients. This study sought to assess the impact of virtual reality applications tailored explicitly for ECHO on children's oxidative stress levels. This was a prospective, randomized, controlled experimental study. Forty-eight children (experimental/24, control/24) aged 7 to 12 years who had an ECHO appointment in the pediatric cardiology outpatient clinic in the 3 months from June to August 2019 participated in the study. Participants whose blood analyses showed hemolysis were eliminated, and the study was completed with 37 children in total: 16 children in the experiment and 21 children in the control. Post hoc power analysis was performed for sample adequacy, and the power of the study was found to be 0.99. A 3D film was prepared for the research and applied to the experimental group before the procedure. All children's oxidative stress levels (cortisol, malondialdehyde, nitric oxide) and glutathione levels were checked after ECHO. The stress hormone cortisol and malondialdehyde levels were lower in the 3D-applied experimental group than in the control group. As another crucial anti-stress antioxidant factor, glutathione level increased in the experimental group compared to the control group (P < .05). The research revealed that the 3D film used to prepare ECHO reduces the stress parameters associated with heart risk and may affect the ECHO measurements. At the same time, the study also proved the positive effect of 3D film preparation by increasing the anti-stress factor.

ConIQA: A deep learning method for perceptual image quality assessment with limited data

Effectively assessing the realism and naturalness of images in virtual (VR) and augmented (AR) reality applications requires Full Reference Image Quality Assessment (FR-IQA) metrics that closely align with human perception. Deep learning-based IQAs that are trained on human-labeled data have recently shown promise in generic computer vision tasks. However, their performance decreases in applications where perfect matches between the reference and the distorted images should not be expected, or whenever distortion patterns are restricted to specific domains. Tackling this issue necessitates training a task-specific neural network, yet generating human-labeled FR-IQAs is costly, and deep learning typically demands substantial labeled data. To address these challenges, we developed ConIQA, a deep learning-based IQA that leverages consistency training and a novel data augmentation method to learn from both labeled and unlabeled data. This makes ConIQA well-suited for contexts with scarce labeled data. To validate ConIQA, we considered the example application of Computer-Generated Holography (CGH) where specific artifacts such as ringing, speckle, and quantization errors routinely occur, yet are not explicitly accounted for by existing IQAs. We developed a new dataset, HQA1k, that comprises 1000 natural images each paired with an image rendered using various popular CGH algorithms, and quality-rated by thirteen human participants. Our results show that ConIQA achieves superior Pearson (0.98), Spearman (0.965), and Kendall’s tau (0.86) correlations over fifteen FR-IQA metrics by up to 5%, showcasing significant improvements in aligning with human perception on the HQA1k dataset.

The New Dimension of Surgery: Telesurgery and Surgical Nursing

In the recent COVID-19 pandemic, it has been observed that surgical patients have turned more towards telemedicine applications to meet their health care needs due to the fact that they cannot apply to hospitals unless they are mandatory and even the majority of non-urgent medical activities, including elective surgeries, are paused. Telesurgery, one of the telehealth concepts in the provision of health services, has emerged as a promising application known as remote surgery, which provides remote surgical care to patients. Today, telesurgical interventions performed away from patients using surgical robots, virtual reality applications, advanced computer and network technologies have become a rising trend in the field of surgery. It is obvious that telesurgery applications, which aim to provide high quality remote surgery with worldwide expertise, have some obstacles due to the fact that it is a very new technology. However, despite the obstacles, it is witnessed that telesurgical interventions are being successfully applied day by day thanks to different application methods. It is predicted that telesurgery, which is expected to reach and serve more patients in the future, will be more widely applied and developed with its high-speed advanced network connection, lower cost rates and reaching all over the world, even to space and the depths of the sea. When we look at the nursing practices in telesurgery, which is a new application area in the field of surgery, it is stated that positive results have been achieved, but the number of studies is still insufficient. Depending on the telesurgery technology, which is expected to develop rapidly in the coming years, it is thought that there will be a rapid increase in the number of studies on telesurgery in the field of surgical nursing. Therefore, in this review, it was aimed to clarify telesurgical interventions, which have been started to be applied by surgeons as a new trend in recent years and which is a very new and highly developed application area for nurses, and to examine the surgical nursing interventions applied in this field.
