An interactive design change methodology using a BIM-based Virtual Reality and Augmented Reality

Changes in design and construction constitute variations from the original design prepared by a design team and are inevitable. Despite the fact that rework has been identified as having adverse effects on performance, there have been limited studies on how to mitigate rework in design changes. Despite improving change management, Building Information Modeling (BIM) is insufficient in mitigating rework. However, the convergence of the capabilities of BIM, Virtual Reality (VR), and Augmented Reality (AR) are integrated solutions to reduce the impact of rework in design change. In this research, we improve the requirements for reworking design changes, which include redesign, information flow, and delivery for users with no experience with BIM. For interactive design change with BIM in VR and AR, the proposed methodology integrates BIM, as-built data from web sources, and VR and AR functions using game engines and programming. In VR and AR, BIM objects are used to create multiple variants that are matched with BIM databases that provide options for design changes. The interactive design change platform is validated in a VR and AR environment and presented multiple design change options for wall elements based on a set required change factor of a building project. This paper highlights the need for a change platform that reduces the rework of design changes in BIM through VR and AR in three main areas redesign, maintaining the flow of information and delivery of solutions for design changes. The VR and AR proposed solution to design change improves rework collaboration and communication among stakeholders of a building project.

Energy- and Quality-Aware Task Offloading for WebVR Service in Terminal-Aided Mobile Edge Network

Web virtual reality (WebVR) is gaining increasing attention as interactive VR experiences become more prevalent. The high energy consumption and strict quality requirements are still significant challenges for its application in the mobile edge network. In this context, content caching and task offloading are promising solutions to save the energy of WebVR. This paper proposes a hybrid decentralized offloading architecture in which the MEC server and multiple terminals jointly participate in the caching and processing of WebVR tasks. In this framework, the graph convolutional network and unsupervised clustering algorithm are jointly applied to process the WebVR service feature graph to achieve FoV-level content caching. Moreover, WebVR users with idle computing resources assist neighboring users with performing tasks. On this basis, we propose a distributed low-bound-based alternative direction method of multiplier (LADMM) algorithm to optimize the offloading mode and the allocation of tasks and computing power resources to minimize system energy consumption. The proposed offloading mode can lower energy consumption while maintaining a good balance between delay performance and resource utilization.

Three-Dimensional Immersive Photorealistic Layered Dissection of Superficial and Deep Back Muscles: Anatomical Study

IntroductionThe distinct anatomy of the superficial and deep back muscles is characterized by complex layered courses, fascial planes, specific vascularization, and innervation. Knowledge of these anatomical parameters is important for some surgical approaches, including lumbar disc herniation, cerebrospinal fluid fistula repair, vascularized muscle pedicle flaps, and posterior fossa extra-intracranial bypass. In the present study, we use modern techniques of three-dimensional (3D) surface scanning to help better illustrate the layered anatomy of the back muscles.Material and methodsWe dissected in layers the back muscles of one cadaver. Every step of the dissection was 3D scanned using a technique called photogrammetry, which allows the extraction of 3D data from 2D photographs. The 3D data were processed using Blender software, and the 3D photorealistic models were uploaded to a dedicated website for 3D visualization. This allows users to see the 3D models from every desktop or mobile device, as well as augmented (AR) and virtual reality (VR) formats.ResultsThe photorealistic 3D models present the back muscles' anatomy in a volumetric manner, which can be visualized on any computer device. The web 3D features, including AR and VR, allow users to zoom, pan, and rotate the models, which may facilitate learning.ConclusionThe technology of photorealistic surface scanning, modern 3D visualization possibilities of web-dedicated formats, as well as advances in AR and VR, have the potential to help with a better understanding of complex anatomy. We believe that this opens the field for further research in the field of medical education.

Immersive virtual reality (VR) training increases the self-efficacy of in-hospital healthcare providers and patient families regarding tracheostomy-related knowledge and care skills

Background:Virtual reality (VR)-based simulation in hospital settings facilitates the acquisition of skills without compromising patient safety. Despite regular text-based training, a baseline survey of randomly selected healthcare providers revealed deficiencies in their knowledge, confidence, comfort, and care skills regarding tracheostomy. This prospective pre–post study compared the effectiveness of regular text- and VR-based intervention modules in training healthcare providers’ self-efficacy in tracheostomy care skills.Methods:Between January 2018 and January 2020, 60 healthcare providers, including physicians, nurses, and respiratory therapists, were enrolled. For the intervention, a newly developed head-mounted display (HMD) and web VR materials were implemented in training and clinical services. Subsequently, in-hospital healthcare providers were trained using either text or head-mounted display virtual reality (HMD-VR) materials in the regular and intervention modules, respectively. For tracheostomy care skills, preceptors directly audited the performance of trainees and provided feedback.Results:At baseline, the degree of trainees’ agreement with the self-efficacy-related statements, including the aspects of familiarity, confidence, and anxiety about tracheostomy-related knowledge and care skills, were not different between the control and intervention groups. At follow-up stage, compared with the regular group, a higher percentage of intervention group’ trainees reported that they are “strongly agree” or “somewhat agree” that the HMD-VR simulation increases their self-efficacy, including the aspects of familiarity and confidence, and reduced their anxiety about tracheostomy-related knowledge and care skills. After implementation, a higher degree of trainees’ average satisfaction with VR-based training and VR materials was observed in the intervention group than in the regular group. Most reported that VR materials enabled accurate messaging and decreased anxiety. The increasing trend of the average written test and hands-on tracheostomy care skills scores among the intervention group trainees was significant compared to those in the regular group. The benefits of HMD-VR simulations and web-VR material-based clinical services for in-hospital healthcare providers and patient families persisted until 3 to 4 weeks later.Conclusion:The current study suggests that VR materials significantly enhance trainees’ self-efficacy (increased familiarity, increased confidence, and reduced anxiety) and their satisfaction with the training, while motivating them to use acquired knowledge and skills in clinical practice.

BIM Big Data Storage in WebVRGIS

In the context of big data and the Internet of Things, with the advancement of geospatial data acquisition and retrieval, the volume of available geospatial data is increasing every minute. Thus, new data-management architecture is needed. We proposed a building information model (BIM) big data-storage-management solution with hybrid storage architecture based on web virtual reality geographical information system (WebVRGIS). BIM is associated with the integration of spatial and semantic information on the various stages of urban building. In this paper, based on the spatial distribution characteristics of BIM geospatial big data, a data storage and management model is proposed for BIM geospatial big data management. The architecture primarily includes Not only Structured Query Language (NoSQL) database and distributed peer-to-peer storage. The evaluation of the proposed storage method is conducted on the same software platform as our previous research about WebVR. The experimental results show that the hybrid storage architecture proposed in this research has a lower response time compared to the traditional relational database in geospatial big data searches. The integration and fusion of BIM big data in WebVRGIS realizes a revolutionary transformation of city information management during a full lifecycle. The system also has great promise for the storage of other geospatial big data, such as traffic data.

Webvr Human-Centered Indoor Layout Design Framework Using a Convolutional Neural Network and Deep Q-Learning

With the rapid development of Web Virtual Reality (WebVR) technology, increasing focus has been placed on this domain. WebVR indoor scenario design studies have been of important value in both academia and industry. However, many bottlenecks still need to be overcome, such as the weak computing capacity and limited memory space available in web browsers. In particular, there are many deficiencies in virtual scenes, i.e., lack of fidelity, low automation and poor scene interactability. In this paper, we propose a novel WebVR indoor furniture layout design framework to enhance the capabilities of automatic furniture layout and significantly enhance the interactiveness of virtual scenarios. In particular, we present a hand-drawn sketch recognition scheme based on the ResNet convolutional neural network (CNN), which can strongly improve scenario interactiveness by allowing the user to conveniently add new furniture by means of free-hand drawing operations rather than tedious manual drag-and-pull operations. In addition, based on a deep Q-learning network (DQN), the best positions (states) for these pieces of furniture (agents) in virtual scenarios can be automatically determined, making it easy to satisfy popular design principles. Finally, we report experiments conducted to validate the feasibility of our proposed framework, and the results fully demonstrate that this framework is completely feasible.
