“…Another frontier of XR involves web technologies, which aim to bring AR and VR capabilities to the web by enabling users to interact with browsers using XR devices [75], [90], [119]. One of the foremost representations of the state of the art in this space is the WebXR Device API 1 , an initiative of the World Wide Web Consortium to standardize access to VR and AR hardware.…”

The intersection between music and Extended Reality (XR) has grown significantly over the past twenty years, amounting to an established area of research today. The use of XR technologies represents a fundamental paradigm shift for various musical contexts as they disrupt traditional notions of musical interaction by enabling performers and audiences to interact musically with virtual objects, agents, and environments. This article both surveys and expands upon the knowledge accumulated in existing research in this area to build a foundation for future works that bring together Music and XR. To this end, we created a freely available dataset of 260 publications in this space and conducted an in-depth analysis covering 199 works in the last decade. We conducted this analysis using a list of conceptual dimensions belonging to technical, artistic, perceptual and methodological domains. This review of the literature is complemented with a set of interviews with domain experts with the goal of establishing a definition for the emergent field of Musical XR, i.e., the field of music in Extended Realities. Based on the results of the conducted review, a research agenda for the field is proposed.

“…Several works are also focusing on the importance of avatar representations [41] within social VR, and investigations related to personal spaces [42]. Within Web3D/WebXR contexts, there are a few works investigating synchronous collaboration, in which multiple users access the same virtual (immersive) space using common web browsers [43]. The most prominent example in the open-source panorama is certainly Mozilla Hubs (https://hubs.mozilla.com/, accessed on 22 November 2021) (based on A-Frame) that allows users to create online virtual meeting spaces, and it's being used also for live workshops with children [44].…”

ATON: An Open-Source Framework for Creating Immersive, Collaborative and Liquid Web-Apps for Cultural Heritage

The web and its recent advancements represent a great opportunity to build universal, rich, multi-user and immersive Web3D/WebXR applications targeting Cultural Heritage field—including 3D presenters, inspection tools, applied VR games, collaborative teaching tools and much more. Such opportunity although, introduces additional challenges besides common issues and limitations typically encountered in this context. The “ideal” Web3D application should be able to reach every device, automatically adapting its interface, rendering and interaction models—resulting in a single, liquid product that can be consumed on mobile devices, PCs, Museum kiosks and immersive AR/VR devices, without any installation required for final users. The open-source ATON framework is the result of research and development activities carried out during the last 5 years through national and international projects: it is designed around modern and robust web standards, open specifications and large open-source ecosystems. This paper describes the framework architecture and its components, assessed and validated through different case studies. ATON offers institutions, researchers, professionals a scalable, flexible and modular solution to craft and deploy liquid web-applications, providing novel and advanced features targeting Cultural Heritage field in terms of 3D presentation, annotation, immersive interaction and real-time collaboration.

“…To extend the functionality of A-Frame and NAF and address some of their limitations, new components were proposed and evaluated by the authors. The components, together with a selection of virtual environments (scenes), constitute a platform called LIRKIS Global-Collaborative Virtual Environments (G-CVE) [8][9][10]. An instance of LIRKIS G-CVE, with all the components described and evaluated here, is available at https://lirkisgcve.herokuapp.com/ (accessed on 22 April 2021).…”

“…The first proposed component, called Enhanced Client Access (ECA) [10], extends NAF with the ability to monitor and control client apps sharing a virtual scene. The second one is 6-DoF SMC (Smartphone Motion Capture) [9], which addresses the lack of Six Degrees of Freedom (6-DoF) motion tracking for smartphones. The 6-DoF motion capture is supported "out of the box" for VR headsets, such as Oculus Touch, Oculus Quest, HTC Focus HTC Vive or Windows MR-compatible devices [11].…”

“…They need additional devices to move, such as gamepads or joysticks, which are less natural for such interaction. The third proposed component, named HoloGOM [9], deals with Microsoft (MS) HoloLens, where available web frameworks do not include access to gesture processing. Therefore, the users are limited to interact only by the clicker device and object manipulation by hand tracking is not available.…”

COVID-19-related quarantine measures resulted in a significant increase of interest in online collaboration tools. This includes virtual reality (VR) or, in more general term, extended reality (XR) solutions. Shared XR allows for activities such as presentations, training of personnel or therapy to take place in a virtual space instead of a real one. To make online XR as accessible as possible, a significant effort has been put into the development of solutions that can run directly in web browsers. One of the most recognized solutions is the A-Frame software framework, created by Mozilla VR team and supporting most of the contemporary XR hardware. In addition, an extension called Networked-Aframe allows multiple users to share virtual environments, created using A-Frame, in real time. In this article, we introduce and experimentally evaluate three components that extend the functionality of A-Frame and Networked-Aframe. The first one extends Networked-Aframe with the ability to monitor and control users in a shared virtual scene. The second one implements six degrees of freedom motion tracking for smartphone-based VR headsets. The third one brings hand gesture support to the Microsoft HoloLens holographic computer. The evaluation was performed in a dedicated local network environment with 5, 10, 15 and 20 client computers. Each computer represented one user in a shared virtual scene. Since the experiments were carried out with and without the introduced components, the results presented here can also be regarded as a performance evaluation of A-Frame and Networked-Aframe themselves.
