“…Both gaming and virtual reality technologies are used everywhere, in the automotive industry, manufacturing industry, trade, marketing, education, medicine, and social media. In Oculus (currently Meta Quest) [23], WebAR [24,25], Metaverse [26,27], Replika Luka [28,29], such technologies have as much potential pros and cons. Due to this, health management and education towards balanced use of devices are important.…”

Traditional sports and esports benefit from the development of Information and Communications Technologies (ICT), including gaming, 4D image/video processing, augmented reality (AR), virtual reality (VR), machine learning (ML), artificial intelligence (AI), big data, high-performance computing (HPC), and cloud computing. On the fuzzy border between the areas of physical and modified reality, both types of sports can coexist. The hardware layer of esports includes PC, consoles, smartphones, and peripherals used to interface with computers, including sensors and feedback devices. The IT layer of esports includes algorithms required in the development of games, online platforms, and virtual reality. The esports community includes amateur and professional players, spectators, esports organizers, sponsors, and other stakeholders. Esports and gaming research spans throughout law (intellectual rights, insurance, safety, and age restrictions), administration (teams, clubs, organizations, league regulations, and tournaments) biology (medicine, psychology, addiction, training and education) Olympic and non- Olympic disciplines, ethical issues, game producers, finance, gambling, data acquisition and analysis. Our article aims to presents selected research issues of esports in the ICT virtualization layer.

“…In general, the synergy of open-source JavaScript AR software such as AR.js with the Three.js library has a variety of applications in interior design [ 29 ], cultural heritage [ 30 ], synthetic visualizations [ 31 ] and education [ 32 , 33 ]. Nitika et al developed a WebRTC marker-based application with AR.js and Three.js to analyze web AR performance, examine potential rendering optimizations and proposing a cloud-based solution [ 34 ].…”

In the context of web augmented reality (AR), 3D rendering that maintains visual quality and frame rate requirements remains a challenge. The lack of a dedicated and efficient 3D format often results in the degraded visual quality of the original data and compromises the user experience. This paper examines the integration of web-streamable view-dependent representations of large-sized and high-resolution 3D models in web AR applications. The developed cross-platform prototype exploits the batched multi-resolution structures of the Nexus.js library as a dedicated lightweight web AR format and tests it against common formats and compression techniques. Built with AR.js and Three.js open-source libraries, it allows the overlay of the multi-resolution models by interactively adjusting the position, rotation and scale parameters. The proposed method includes real-time view-dependent rendering, geometric instancing and 3D pose regression for two types of AR: natural feature tracking (NFT) and location-based positioning for large and textured 3D overlays. The prototype achieves up to a 46% speedup in rendering time compared to optimized glTF models, while a 34 M vertices 3D model is visible in less than 4 s without degraded visual quality in slow 3D networks. The evaluation under various scenes and devices offers insights into how a multi-resolution scheme can be adopted in web AR for high-quality visualization and real-time performance.

“…Figure 6 shows an image captured through the device after loading the actual model and the 3D model in the WebXR environment. The image was captured when moving to the left ( 2 ) and right ( 3 ) from the image at ( 1 ). When an object was loaded based on the anchor ( a ) shown in Figure 4a,b, the difference between the position of the real model and the 3D model was checked.…”

“…In other words, it is used to provide extended reality in a web environment. In the past, extensive studies for supporting virtual environments in a web environment have been performed, such as WebVR application programming interface (API) and WebAR API [1,2]. However, because these APIs were developed to service a particular virtual environment, supporting other virtual environments became difficult and modifications were time-consuming.…”

Performance Evaluation of Ground AR Anchor with WebXR Device API

et al. 2021

View full text Add to dashboard Cite

Recently, the development of 3D graphics technology has led to various technologies being combined with reality, where a new reality is defined or studied; they are typically named by combining the name of the technology with “reality”. Representative “reality” includes Augmented Reality, Virtual Reality, Mixed Reality, and eXtended Reality (XR). In particular, research on XR in the web environment is actively being conducted. The Web eXtended Reality Device Application Programming Interface (WebXR Device API), released in 2018, allows instant deployment of XR services to any XR platform requiring only an active web browser. However, the currently released tentative version has poor stability. Therefore, in this study, the performance evaluation of WebXR Device API is performed using three experiments. A camera trajectory experiment is analyzed using ground truth, we checked the standard deviation between the ground truth and WebXR for the X, Y, and Z axes. The difference image experiment is conducted for the front, left, and right directions, which resulted in a visible difference image for each image of ground truth and WebXR, small mean absolute error, and high match rate. In the experiment for measuring the 3D rendering speed, a frame rate similar to that of real-time is obtained.
