“…Additionally, these spatio-temporal references were integrated in a rather seamless manner, allowing for the automatic transmission of information as the users naturally interacted with their interfaces. As opposed to introducing additional dedicated actions in regard to what information to share and when, such as used by Welsford-Ackroyd et al (2020), Reski et al (2020b), andPeter et al (2018), and based on our observations, this seemed to have allowed the collaborators to naturally interact with each other, seamlessly picking up and referring to their partner's context without noticeable action delays, i.e., without the need to wait for a specific collaborative signal.…”

“…Similarly, Welsford-Ackroyd et al ( 2020) evaluated their proposed system design that allows a non-immersed user, typically in a role as an outside spectator, to actively collaborate with a VR user using a large scale immersive display. Camera control and pointing features were provided to the spectator, the later of which clearly facilitated the communication between the two collaborators in a task scenario where the VR user had to place objects at certain locations as indicated by the spectator (Welsford-Ackroyd et al, 2020). Their system shows similarities to the VR-Guide one by Peter et al (2018) in such that the nonimmersed user directs the immersed one to a point-of-interest through visual highlights in the VR environment.…”

“…For this purpose, we aim to investigate collaborative aspects in a scenario where two analysts explore a multivariate dataset at the same time from different perspectives, immersed and non-immersed, each assuming a distinct role in order to contribute to the joint data exploration activity. While various synchronous asymmetric research assumes the non-immersed user commonly in a more "guiding" or "assisting" role (Peter et al, 2018;Thomsen et al, 2019;Welsford-Ackroyd et al, 2020;Ens et al, 2021), our objective is to provide a use case where the involved analysts may contribute more equally, each based on their application and viewpoint. Furthermore, as IA technologies become more accessible in the future, it is of value to the community to investigate the integration with existing tools and practices that are common in the InfoVis and VA community, as for instance emphasized by Wang et al (2019) and Cavallo et al (2019).…”

“…Based on our observations, it is likely that the task answer sheet responsibility has given the non-immersed user a little bit the edge towards being the task director. Even though the non-immersed user assumed such a "leading" role at times, we do not consider this to be the same as the dedicated guiding roles such as discussed by Welsford-Ackroyd et al (2020) or Peter et al (2018), but instead an overall rather balanced interplay between the collaborators for their own purposes that is conceptually similar to the scenarios as described by Lee et al (2020), Sugiura et al (2018), andGugenheimer et al (2017).…”

Collaboration is an essential part of data analysis, allowing multiple users to combine their expertise and to debate about the interpretation of data discoveries using their contextual knowledge. The design of collaborative interfaces within the context of Immersive Analytics remains challenging, particularly due to the various user-centered characteristics of immersive technologies. In this article, we present the use case of a system that enables multiple users to synchronously explore the same data in a collaborative scenario that combines immersive and non-immersive interfaces in an asymmetric role setup. Such a setup allows for bridging the gap when applying heterogeneous display and interaction technologies, enabling each analyst to have an independent and different view of the data, while maintaining important collaborative aspects during the joint data exploration. We developed an immersive VR environment (head-mounted display, 3D gestural input) and a non-immersive desktop terminal (monitor, keyboard and mouse) centered around spatio-temporal data exploration. Supported through a real-time communication interface, synchronous collaborative features are integrated in both interfaces, facilitating the users in their ability to establish a shared context and to make spatio-temporal references. We conducted an empirical evaluation with five participant pairs (within-subject design) to investigate aspects of usability, user engagement, and collaboration during a confirmative analysis task. Synthesis of questionnaire results in combination with additional log file analysis, audio activity analysis, and observations, revealed good usability scores, high user engagement, as well as overall close and balanced collaboration of enthusiastic pairs during the task completion independent of their interface type, validating our system approach in general. Further supported through the self-constructed Spatio-Temporal Collaboration Questionnaire, we are able to contribute with discussion and considerations of the presented scenario and the synchronous collaborative features for the design of similar applications.

TeleGate: Multi-user Semi-teleportation for Remote Collaboration in Mixed Reality 360-Videos

Telepresence systems enable people to feel present in a remote space while their bodies remain in their local space. To enhance telepresence, the remote environment needs to be captured and visualised in an immersive way. For instance, 360-degree videos (360-videos) shown on head-mounted displays (HMDs) provide high fidelity telepresence in a remote place. Mixed reality (MR) in 360-videos enables interactions with virtual objects blended in the captured remote environment while it allows telepresence only for a single user wearing HMD. For this reason, it has limitations when multiple users want to experience telepresence together and naturally collaborate within a teleported space. This thesis presents TeleGate, a novel multi-user teleportation platform for remote collaboration in a MR space. TeleGate provides "semi-teleportation" into the MR space using large-scale displays, acting as a bridge between the local physical communication space and the remote collaboration space created by MR with captured 360-videos. Our proposed platform enables multi-user semi-teleportation to perform collaborative tasks in the remote MR collaboration (MRC) space while allowing for natural communication between collaborators in the same local physical space. We implemented a working prototype of TeleGate and then conducted a user study to evaluate our concept of semi-teleportation. We measured the spatial presence, social presence while participants performed remote collaborative tasks in the MRC space. Additionally, we also explored the different control mechanisms within the platform in the remote MR collaboration scenario. In conclusion, TeleGate enabled multiple co-located users to semi-teleport together using large-scale displays for remote collaboration in MR 360-videos.
