“…Kim et al [13] proposed a dynamic/adaptive algorithm that could control the power allocation in 60-GHz transceivers to achieve the time-average energy efficiency for VR data delivery while preserving the queue stabilization. In [14], the feasibility of wireless VR using WiGig was examined through performance measurements and simulation studies. In [15], the feasibility of wireless VR over WiFi was examined via testbed experiments, and the challenges were discussed.…”

Wireless virtual reality (VR) is a promising direction for future VR systems that offloads heavy computation to a remote processing entity and wirelessly receives high-quality streams. WiGig and WiFi are representative solutions to implement wireless VR; however, they differ in communication bandwidth and reliability. Our testbed experiments show that the performance of WiGig and VR traffic generation strongly correlates with and consequently can be predicted from a user’s motion. Based on this observation, we develop a wireless VR system that exploits the benefits of both links by switching between them and controlling the VR frame encoding for latency regulation and image quality enhancement. The proposed system predicts the performance of the links and selects the one with a higher capacity in an opportunistic manner. It adjusts the encoding rate of the host based on the motion-aware prediction of the frame size and estimated latency of the selected link. By evaluating the testbed data, we demonstrate that the proposed system outperforms a WiGig-only system with a fixed encoding rate in terms of latency regulation and image quality.

“…In our case, there are ongoing discussions about how to bring the insights of the control room to the participants working from home, through AR and VR, so that planners and BIM managers can view the control room while they are not on-site and as if they are in the weekly meetings. This vision would include adopting other technologies, such as the Tactile Internet (Na et al, 2020).…”

Extending current work on visualization in the Architecture, Engineering, and Construction (AEC) sector, this paper describes an industry-led collaborative research and innovation project to develop and use a control room on the construction site. The work is inspired by NASA mission operations, with its large-scale visual display. It addresses the challenges of visualizing realtime construction data. Working with a main contractor, technology companies, and other researchers, we first give an overview of the progress of the overall project to date and discuss our contributions on requirements, realtime simulation of construction data, and visualization. We conclude by discussing the contribution to work on visualizing construction.

“…These iAPR servers are located on the cloud to ensure high service availability, and they are accessed from user devices through a networking infrastructure [46]. It is worth noting that the web-based application is designed to work on the Internet protocol (IP) stack; therefore, the iAPR system is able to adapt to almost all popular networking technologies such as cellular and WiFi access networks [47,48].…”

Hazard investigation education plays a crucial role in equipping students with adequate knowledge and skills to avoid or eliminate construction hazards at workplaces. With the emergence of various visualization technologies, virtual photoreality as well as 3D virtual reality have been adopted and proved advantageous to various educational disciplines. Despite the significant benefits of providing an engaging and immersive learning environment to promote construction education, recent research has also pointed out that virtual photoreality lacks a 3D object anatomization tools to support learning, while 3D-virtual reality cannot provide a real-world environment. In recent years, research efforts have studied virtual reality applications separately, and there is a lack of research integrating these technologies to overcome limitations and maximize advantages for enhancing learning outcomes. In this regard, the paper develops a construction hazard investigation system leveraging object anatomization on an Interactive Augmented Photoreality platform (iAPR). The proposed iAPR system integrates virtual photoreality with 3D-virtual reality. The iAPR consists of three key learning modules, namely Hazard Understanding Module (HUM), Hazard Recognition Module (HRM), and Safety Performance Module (SPM), which adopt the revised Bloom's taxonomy theory. A prototype is developed and evaluated objectively through interactive system trials with educators, construction professionals, and learners. The findings demonstrate that the iAPR platform has significant pedagogic methods to improve learner's construction hazard investigation knowledge and skills, which improve safety performance.
