“…The application of the metaverse is already being carried out as highlighted by works in the literature, such as in [38], wherein the metaverse was applied together with VR in teaching; in [39], wherein the authors addressed the collaboration of personnel in 3D virtual environments; and in [4], wherein a mixed-reality approach in communication spaces was explored. As for framework proposals, VR experiences in VR and metaverse were introduced in [40][41][42][43].…”

“…Computer-generated virtual world is a space where users can interact with objects in an immersive way, freely explore all spaces, socialize with audio and speech with groups of people connected in the same session as if they were in the real world [3]. Virtual reality (VR) can also display complex content or useful data innovatively, regardless of the limitations of our physical reality [4]. Such an environment has the potential to elevate collaboration, communication, and learning to a higher level of quality compared to traditional technologies such as 2D display.…”

Virtual reality (VR) has been brought closer to the general public over the past decade as it has become increasingly available for desktop and mobile platforms. As a result, consumer-grade VR may redefine how people learn by creating an engaging “hands-on” training experience. Today, VR applications leverage rich interactivity in a virtual environment without real-world consequences to optimize training programs in companies and educational institutions. Therefore, the main objective of this article was to improve the collaboration and communication practices in 3D virtual worlds with VR and metaverse focused on the educational and productive sector in smart factory. A key premise of our work is that the characteristics of the real environment can be replicated in a virtual world through digital twins, wherein new, configurable, innovative, and valuable ways of working and learning collaboratively can be created using avatar models. To do so, we present a proposal for the development of an experimental framework that constitutes a crucial first step in the process of formalizing collaboration in virtual environments through VR-powered metaverses. The VR system includes functional components, object-oriented configurations, advanced core, interfaces, and an online multi-user system. We present the study of the first application case of the framework with VR in a metaverse, focused on the smart factory, that shows the most relevant technologies of Industry 4.0. Functionality tests were carried out and evaluated with users through usability metrics that showed the satisfactory results of its potential educational and commercial use. Finally, the experimental results show that a commercial software framework for VR games can accelerate the development of experiments in the metaverse to connect users from different parts of the world in real time.

“…For example, the high-performance graphics card renders complex 3D graphics in real-time, and the virtual reality technology provides users with an immersive experience [40,41]. We can build a three-dimensional virtual scene with HMD [2,42,43], and then create a whiteboard in it [44,45]. Moreover, there is a controller that can be used as an input device to provide a natural writing experience [46,47].…”

The COVID-19 pandemic has increased the significance of remote collaboration. This study proposes a virtual reality (VR) whiteboard system that enables remote collaboration among multiple participants using natural handwriting. In total, three experiments were conducted to investigate, respectively, collaboration efficiency, user experience, and system delay. First, we compared the collaboration efficiency of the traditional whiteboard, the electronic whiteboard, and the proposed virtual reality whiteboard in a series of controlled experiments. It was discovered that the VR whiteboard significantly improves collaboration efficiency in comparison to the mouse-based electronic whiteboard and is comparable to the traditional whiteboard. Second, we assessed the user experience with a survey scale (questionnaires). The subsequent results demonstrate that the VR whiteboard provides a superior user experience in terms of efficiency, usability, etc., compared to the traditional whiteboard. We also measured an end-to-end latency of approximately 115 milliseconds, which is sufficient for remote collaboration.

“…The two seating positions tested were selected to model various settings where people sit around a table or share the same perspective with respect to physical artifacts. Similar settings have been studied in prior CSCW works concerning the spatial arrangements of remote communication systems or tabletop interfaces (Yamashita et al, 1999;Tang et al, 2010;He et al, 2019). In each condition, the participant pair needed to complete a set of 20 trials (one trial for each of the 16 targets, plus four additional trials as decoys to prevent participants from predicting remaining targets).…”

The Effects of Incorrect Occlusion Cues on the Understanding of Barehanded Referencing in Collaborative Augmented Reality

In many collaborative tasks, the need for joint attention arises when one of the users wants to guide others to a specific location or target in space. If the collaborators are co-located and the target position is in close range, it is almost instinctual for users to refer to the target location by pointing with their bare hands. While such pointing gestures can be efficient and effective in real life, performance will be impacted if the target is in augmented reality (AR), where depth cues like occlusion may be missing if the pointer’s hand is not tracked and modeled in 3D. In this paper, we present a study utilizing head-worn AR displays to examine the effects of incorrect occlusion cues on spatial target identification in a collaborative barehanded referencing task. We found that participants’ performance in AR was reduced compared to a real-world condition, but also that they developed new strategies to cope with the limitations of AR. Our work also identified mixed results of the effect of spatial relationships between users.
