Item A state-of-the-art analysis of virtual reality applications in construction health and safety(Elsevier BV, 2024-06-08) Akindele, Nelson; Taiwo, Ridwan; Sarvari, Hadi; Oluleye, Benjamin I.; Awodele, Imoleayo A.; Olaniran, Temitope O.The construction industry contends with high injury rates, emphasizing the need for innovative preventive measures in construction health and safety (CHS). While previous studies have investigated the potential ap plications of virtual reality (VR) in the construction industry for different purposes, an in-depth study on VR in the CHS context is lacking. Hence, this study provides a state-of-the-art analysis of VR applications in CHS, employing a dual scientometric and systematic review approach. A scientometric analysis is conducted to examine annual publication trends, keyword co-occurrences, and science mapping of publication outlets, alongside mapping the contributions of leading countries in this domain. This analysis reveals a marked increase in research interest and identifies central thematic connections within the body of literature. The systematic review assesses VR technologies, including immersive, desktop-based, BIM-based, 3D game-based, and augmented reality, addressing their roles in hazard identification and safety training. The study also underscores challenges like infrastructure, content modeling, and interoperability and proposes directions for future research. Recommendations include probing into VR’s role in cognitive safety risks and the impact of users’ prior safety knowledge on learning outcomes. This study suggests that developing tailored VR experiences for specific user groups could significantly advance safety practices in the construction industry.Item Coalition of 6G and blockchain in AR/VR space : challenges and future directions(Institute of Electrical and Electronics Engineers (IEEE), 2021) Bhattacharya, Pronaya; Saraswat, Deepti; Dave, Amit; Acharya, Mohak; Tanwar, Sudeep; Sharma, Gulshan; Davison, I. E.The digital content wave has proliferated the financial and industrial sectors. Moreover, with the rise of massive internet-of-things, and automation, technologies like augmented reality (AR) and virtual reality (VR) have emerged as prominent players to drive a range of applications. Currently, sixth-generation (6G) networks support enhanced holographic projection through terahertz (THz) bandwidths, ultra-low latency, and massive device connectivity. However, the data is exchanged between autonomous networks over untrusted channels. Thus, to ensure data security, privacy, and trust among stakeholders, blockchain (BC) opens new dimensions towards intelligent resource management, user access control, audibility, and chronology in stored transactions. Thus, the BC and 6G coalition in future AR/VR applications is an emerging investigative topic. To date, authors have proposed surveys that study the integration of BC and 6G in AR/VR in isolation, and hence a coherent survey is required. Thus, to address the gap, the survey is the first-of-its-kind to investigate and study the coalition of BC and 6G in AR/VR space. Based on the proposed research questions in the survey, a solution taxonomy is presented, and different verticals are studied in detail. Furthermore, an integrative architecture is proposed, and open issues and challenges are presented. Finally, a case study, BvTours, is presented that presents a unique survey on BC-based 6G-assisted AR/VR virtual home tour service. The survey intends to propose future resilient frameworks and architectures for different industry 4.0 verticals and would serve as starting directions for academia, industry stakeholders, and research organizations to study the coalition of BC and 6G in AR/VR in industrial applications, gaming, digital content manufacturing, and digital assets protection in greater detail.
