“…In the same year, Medeiros et al (2012) analyzed the applicability of the 3C collaboration model as a methodology to model and define collaborative tools in the development of a collaborative virtual reality application. The presented case study illustrated the selection and evaluation of different tools that aim to support the actions of communication, cooperation and coordination between users that interact in a virtual environment.…”

Although Virtual Reality technology was first developed almost sixty years ago, there has been little survey work giving an overview on how research in VR, AR and MR evolved in Brazil along with their future trends. We provide such analysis by reviewing the development made since the first WRV event, back in 1997, until SVR 2020. The first 22 event editions may help understand how the area was explored and provide a roadmap for future research. The 609 full papers analyzed were compiled into an open catalog, available on the internet. It features important filter capabilities, enabling the quick selection of papers based on citation number, conference topic, area of application, user experiments, statistical analysis and so on. We hope this tool to be of great value to the field, and also for helping researchers decide which topics should be explored when they are beginning their own studies in the area. In this analysis, we also refer to the most frequent authors in the area and how they contributed to the field based on their expertise and research group.

This paper presents a collaborative software development platform allowing traditional and virtual universities actors who are geographically distant to work on a software development project using common (usual) programming languages.In the context of the virtual universities operating in the field of STEM (Science, Technology, Engineering and Mathematics), pratical classes are needed to acquire and to enhance the necessary skills particularly in software engineering.To the various actors of these digital and traditional universities making some e-learning, this paper supplies a preconfigured collaborative software development environment including synchronization of files belonging to a given project, instant messaging, audio and video. Our platform has an administration interface allowing the management of permissions and preconfigured virtual machines allocation to the various actors.To reach our goals, we used the XMPP protocol for instant messaging and file synchronization. Then, we used WebRTC for audio and video between actors. Finally, we used the RDP protocol to allow the access to the virtual machines.In this work, we show how our platform was used by the Virtual University of the Senegal (UVS) teachers and students in the field of Applied Mathematics and Computer Science for some pratical classes about C/C++, Java, Python and PHP programming languages.Tags: collaborative software development platform, virtual university, STEM education, e-learning

“…Manuscript submitted to ACM Previous works on collaboration between immersed and non-immersed users were designed for constrained scenarios such as specially designed games [14,15,38]. Our approach targets generic asymmetric collaboration/presentation scenarios where users have different affordances and tasks, but need to be able to share their experience, sense of immersion, and communicate about the environment (through the use of pointing gestures).…”

In this paper, we present a system that allows a user with a head-mounted display (HMD) to communicate and collaborate with spectators outside of the headset. We evaluate its impact on task performance, immersion, and collaborative interaction. Our solution targets scenarios like live presentations or multi-user collaborative systems, where it is not convenient to develop a VR multiplayer experience and supply each user (and spectator) with an HMD. The spectator views the virtual world on a large-scale tiled video wall and is given the ability to control the orientation of their own virtual camera. This allows spectators to stay focused on the immersed user's point of view or freely look around the environment. To improve collaboration between users, we implemented a pointing system where a spectator can point at objects on the screen, which maps an indicator directly onto the objects in the virtual world. We conducted a user study to investigate the influence of rotational camera decoupling and pointing gestures in the context of HMD-immersed and non-immersed users utilizing a large-scale display. Our results indicate that camera decoupling and pointing positively impacts collaboration. A decoupled view is preferable in situations where both users need to indicate objects of interest in the scene, such as presentations and joint-task scenarios, as it requires a shared reference space. A coupled view, on the other hand, is preferable in synchronous interactions such as remote-assistant scenarios.
