“…Recently, the concept of SAPIENS-in-XR [59] was introduced, for which the authors employed a technical performance evaluation, where they "injected events in SAPIENS-in-XR architecture at random moments of time sampled from Poisson distributions with the rates λ = 10, 5, and 1, corresponding to different expected numbers of notifications occurring over a 5second time interval" [59, p. 8]. In the same manner, a mixed reality system consisting of four different scenes (experiences) can be implemented and, a Poisson distribution could be used in order to generate random moments when the user could be notify about the transit possibility; in this way, on different moments of time, the user is able to switch his/her mixed reality experience, sequentially.…”

We explore in this paper theoretical contributions that are related to Milgram and Kishino's Reality Virtuality Continuum by conducting a systematic literature review. From this study, we draw inspiration for our proposed mathematical formalization of combining multiple Reality-Virtuality Continua in a single, mixed reality experience. Also, we provide a definition for XR transition protocol. To complete our contribution, we discuss two potential examples that will exemplify our formalization and identify future work to be addressed.

“…Recent works such as BeHere [17] invokes gesture and avatar into collaborative environments. Interaction-attention in XR has been explored [18], multiscale interaction in XR. The user could take on different perspectives in the streamed VR and shrink or enlarge their avatar similar to multiscale [19,20].…”

Multi-scale interaction in Mixed Reality (MR) allows the avatars to shrink down themselves into a small size or enlarge into giant size. Multi-scale in MR is important in some situations that required precise avatar’s measurements to interact and manipulate with the content. However, the correct or appropriate scaling for multi-scale still remain unsolved in MR, very less people work in Augmented Reality (AR). It is critical to align precisely the way humans perceive the virtual world with the ways perceiving the real world. Therefore, this paper aims to produce a correct multi-scale technique for VR and AR users in MR environment. This paper presents a preliminary study on the previous works multi-scale techniques for MR remote collaboration. Then it explains the development of a multi-scale interaction between VR and AR users for the MR environment. Finally, this paper shows the results and implement the technique into an application. The results used to measure how multi-scale interaction can be leveraged with MR technology. The remote MR application involves AR and VR users with different interaction techniques.

Haptic feedback, a natural component of our everyday interactions in the physical world, requires careful design in virtual environments. However, feedback location can vary from the fingertip to the finger, hand, and arm due to heterogeneous input/output technology used for virtual environments, from joysticks to controllers, gloves, armbands, and vests. In this work, we report on the user experience of touch interaction with virtual displays when vibrotactile feedback is delivered on the finger, wrist, and forearm. In a first controlled experiment with fourteen participants and virtual displays rendered through a head-mounted device, we report a user experience characterized by high perceived enjoyment, confidence, efficiency, and integration as well as low perceived distraction, difficulty, and confusion. Moreover, we highlight participants’ preferences for vibrotactile feedback on the finger compared to other locations on the arm or through the VR controller, respectively. In a follow-up experiment with fourteen new participants and physical touchscreens, we report a similar preference for the finger, but also specific nuances of the self-reported experience, not observed in the first experiment with virtual displays. Overall, our results depict an enhanced user experience when distal vibrotactile feedback is available over no vibrations at all during interactions with virtual and physical displays, for which we propose future work opportunities for augmented interactions in virtual worlds.
