The Knowledge Graph As The Interoperability Foundation For An Augmented Reality Application: The Case At The Dutch Land Registry

Abstract

I. INTRODUCTIONThe metaverse is an iteration of the Internet with immersive and hyperreal 3D digital virtual worlds. It can recreate the physical world using technologies such as digital twins, avatars, and holograms. Besides creating digital models of physical environments, the metaverse allows the existence of virtual information, objects, human beings, and environments that do not exist in the physical world. The mixture of real and virtual content in the metaverse can significantly improve users' capabilities for work, entertainment, education, healthcare, and manufacturing [1]. Development of the metaverse includes three major areas:(1) metaverse content/service design, (2) metaverse core and edge network design, and (3) fully connected networks for metaverse devices in the physical world. First, the metaverse virtual content and services emphasize social connections and interactions with the physical world. The design of virtual content and services requires digital computing, modeling, and rendering technologies. Second, the core and edge networks are needed to deliver metaverse content and services to end users. Although existing computer networks can provide basic metaverse services, the newly-proposed compute-and data-intensive networks [2] and the New Internet Protocol (New IP) [3] are efficient in processing metaverse data packets. Last, metaverse devices, sensors, actuators, and displays must be fully connected considering different levels of data rates, latency, and reliability. This keynote will cover all three areas with special emphasis on wireless communication and networking in the second and third areas. 5G and beyond wireless systems have enabled the creation and development of the metaverse. However, their performance cannot support the high Quality-of-Experience (QoE) metaverse. The most popular tools to get access to the metaverse are the extended reality (XR) Head-Mounted Displays (HMDs) [4]. However, some users experience frustration, eye strain, sickness, and prolonged use is prohibitive due to their large weight and low resolution of the HMDs [5]. Although working and living in the metaverse provides various choices and support that are not available in reality, the experience of using existing HMDs is not convenient and even creates anxiety for some users, according to a recent study [5].The metaverse has become one of the driving applications for 6G and beyond wireless systems since 5G and beyond wireless systems cannot fully address wireless communication and networking issues. It is anticipated that the 6G and beyond wireless systems will provide high-data-rate, low-latency, high-reliability, and fully-connected data communications for metaverse devices, which can enable users to comfortably enter and use metaverse applications with high QoEs. In this keynote, we will focus on wireless communication and networking challenges for metaverse accessing technologies, namely, the XR technologies, including Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR), and Hologr...
