Reality capture allows for the reconstruction, with a high accuracy, of the physical reality of cultural heritage sites. Obtained 3D models are often used for various applications such as promotional content creation, virtual tours, and immersive experiences. In this paper, we study new ways to interact with these high-quality 3D reconstructions in a real-world scenario. We propose a user-centric product design to create a virtual reality (VR) application specifically intended for multi-modal purposes. It is applied to the castle of Jehay (Belgium), which is under renovation, to permit multi-user digital immersive experiences. The article proposes a high-level view of multi-disciplinary processes, from a needs analysis to the 3D reality capture workflow and the creation of a VR environment incorporated into an immersive application. We provide several relevant VR parameters for the scene optimization, the locomotion system, and the multi-user environment definition that were tested in a heritage tourism context.

Mixed Approach

What if customer experience was the primary driver of digital transformation? Indeed, new hybrid experiences have emerged thanks to daily-life technologies that fused both digital and physical worlds. This kind of experience uses applications and connected objects (IoT) to adapt and respond to consumer needs. Augmented reality and virtual reality are one of the most functionally and emotionally memorable phygital experiences that create value for customers. In this chapter, the authors chose heritage tourism as the study field for different reasons. While the adoption of augmented and virtual reality is gaining grownd, cultural heritage sites have started to consider the possibilities offered by these new and innovative technologies. This industry is starting to integrate AR and VR in several ways to attract more people. However, it is necessary to study how modern technology can be developed and implemented in a meaningful way to improve the tourist's experience. An AR- and VR-based mobile application has been developed and tested at Antonine's Baths in Carthage, Tunisia.

High-Performance Computer (HPC) is computer systems that are built to be able to solve computational loads. HPC can provide a high-performance technology and short the computing processes timing. This technology was often used in large-scale industries and several activities that require high-level computing, such as rendering virtual reality technology. In this research, we provide Tawaf’s Virtual Reality with 1000 of Pilgrims and realistic surroundings of Masjidil-Haram as the interactive and immersive simulation technology by imitating them with 3D models. Thus, the main purpose of this study is to calculate and to understand the processing time of its Virtual Reality with the implementation of tawaf activities using various platforms; such as computer and Android smartphone. The results showed that the outer-line or outer rotation of Kaa’bah mostly consumes minimum times although he must pass the longer distance than the closer one.  It happened because the agent with the closer area to Kaabah is facing the crowded peoples. It means an obstacle has the more impact than the distances in this case.

Virtual Reality (VR) has been used in industries since the 1960s. However, the recent development of hardware and software has made it possible for VR technologies to become widely adopted by the mass market with the highest level of immersion and affordable price. However, building platforms for VR technologies will require many active users and their engagement in project development. Those activities will include platform activities, content creation, social media marketing, processing power, and storage. For that purpose, we introduce VoRtex enterprise high-level software architecture and decentralized blockchain solution. Introduced VoRtex enterprise high-level software architecture will be used to develop blockchain-based virtual world (VW) platform with VR support. The goal of the VW platform is to support the development of education, certification and massive open online courses (MOOC). A blockchain component inside the VW platform will be used for engaging users in project development through collaboration and content sharing. Active users that promote platform content will get rewards for contributions using cryptocurrency. Also, we will showcase this feature on the VoRtex platform prototype where the user earns cryptocurrencies for activity inside the VW. In the end, we will evaluate the proposed solution

Despite significant advances in the treatment and rehabilitation of stroke, level of post-stroke disability remains at a fairly high level. Recent innovative developments in the rehabilitation of these patients provide good results in terms of functional outcome. One of such developments is method of virtual reality (VR), which affects not only the speed and volume of regaining movement, as well as coordination, but also normalizes the psycho-emotional background, increasing the motivation of patients to improve the recovery process. This article provides a literature review of the use of the VR method in the rehabilitation of post-stroke patients, neurophysiological aspects of recovery of lost functions using this method are considered.

Abstract Tridimensional (3D) rendering of volumetric neuroimaging is increasingly been used to assist surgical management of brain tumors. New technologies allowing immersive virtual reality (VR) visualization of obtained models offer the opportunity to appreciate neuroanatomical details and spatial relationship between the tumor and normal neuroanatomical structures to a level never seen before. We present our preliminary experience with the Surgical Theatre, a commercially available 3D VR system, in 60 consecutive neurosurgical oncology cases. 3D models were developed from volumetric CT scans and MR standard and advanced sequences. The system allows the loading of 6 different layers at the same time, with the possibility to modulate opacity and threshold in real time. Use of the 3D VR was used during preoperative planning allowing a better definition of surgical strategy. A tailored craniotomy and brain dissection can be simulated in advanced and precisely performed in the OR, connecting the system to intraoperative neuronavigation. Smaller blood vessels are generally not included in the 3D rendering, however, real-time intraoperative threshold modulation of the 3D model assisted in their identification improving surgical confidence and safety during the procedure. VR was also used offline, both before and after surgery, in the setting of case discussion within the neurosurgical team and during MDT discussion. Finally, 3D VR was used during informed consent, improving communication with families and young patients. 3D VR allows to tailor surgical strategies to the single patient, contributing to procedural safety and efficacy and to the global improvement of neurosurgical oncology care.

Development And Management

Development and management of heritage tourism attractions pose several challenges, such as lack of financial resources and political support. heritage sites and attractions often include numerous attributes (e.g., education, guided tours, shopping for local products) that can be provided at various levels of involvement and interest. however, the financial constraints of heritage tourism sites inhibit the ability to improve programs and services. The purpose of this study is to identify and compare the preferences of consumers and ambassadors (i.e., local tourism and community leaders) for improving management programs and services of the South Carolina National heritage Corridor using a choice modeling method. Both groups were generally in favor of developing more opportunities for local shopping, education/interpretation, and enhancing the cultural experience when visiting the South Carolina National heritage Corridor. however, ambassadors were more in favor of developing education/interpretation and the cultural experience compared to consumers. As agencies develop programs and services designed to increase visitation, preference information from different constituent groups are valuable to effectively decide what programs and services to develop.

3D maps such as Google Earth and Apple Maps (3D mode), in which users can see and navigate in 3D models of real worlds, are widely available in current mobile and desktop environments. Users usually use a monitor for display and a keyboard/mouse for interaction. Head-mounted displays (HMDs) are currently attracting great attention from industry and consumers because they can provide an immersive virtual reality (VR) experience at an affordable cost. However, conventional keyboard and mouse interfaces decrease the level of immersion because the manipulation method does not resemble actual actions in reality, which often makes the traditional interface method inappropriate for the navigation of 3D maps in virtual environments. From this motivation, we design immersive gesture interfaces for the navigation of 3D maps which are suitable for HMD-based virtual environments. We also describe a simple algorithm to capture and recognize the gestures in real-time using a Kinect depth camera. We evaluated the usability of the proposed gesture interfaces and compared them with conventional keyboard and mouse-based interfaces. Results of the user study indicate that our gesture interfaces are preferable for obtaining a high level of immersion and fun in HMD-based virtual environments.

Escape rooms exist in various forms, including real-life facilities, board games, and digital implementations. The underlying idea is always the same: players have to solve many diverse puzzles to (virtually) escape from a locked room. Within the last decade, we witnessed a rapidly increasing popularity of such games, which also amplified the amount of related research. However, the respective academic landscape is mostly fragmented in its current state, lacking a common model and vocabulary that would withstand these games' variety. This manuscript aims to establish such a foundation for the analysis and construction of escape rooms. In a first step, we derive a high-level design framework from prior literature. Then, as our main contribution, we establish an atomic puzzle taxonomy that closes the gap between the analog and digital domains. The taxonomy is developed in multiple steps: we compose a basic structure based on previous literature and systematically refine it by analyzing 39 analog and digital escape room games, including recent virtual reality representatives. The final taxonomy consists of mental, physical, and emotional challenges, thereby providing a robust and approachable basis for future works across all application domains that deal with escape rooms or puzzles in general.

Virtual reality in one form or another has been around for over 50 years, most notably in entertainment and business environments. Technology-focused teachers have been leading the way with attempts at utilising and integrating virtual reality into K-12 and Higher Education. However, as quickly as technology changes so does the enthusiasm for the use in educational contexts. Much of this is due to the high-level cost (time and money) with no evidence-based educational return. In 2020 the global pandemic forced the education sector to innovate to provide authentic learning environments for students. The time is right for virtual reality to take centre stage. Over 171 million people worldwide currently use virtual reality, and the market in education is expected to grow by 42% over the next five years. This paper focuses on a range of virtual reality literature encompassing work across the spectrum of software and hardware, identifying where more educational implementation and research needs to be done and providing a perspective on future possibilities focusing on current affordances.
