“…A user study demonstrated its feasibility though performance and selection accuracy were lower than using a conventional controller. Weissker et al (2019) presents a group based teleportation technique named Multi-Ray Jumping that allows two users to navigate a VE together. It was found to improve planning accuracy (performance), reduce cognitive load and lower disorientation for passengers.…”

Teleportation is a widely implemented virtual locomotion technique that allows users to navigate beyond the confines of available tracking space with a low possibility of inducing virtual reality (VR) sickness. This paper provides a comprehensive overview of prior research on teleportation. We report results from user studies that have evaluated teleportation in comparison to other locomotion methods and survey improved versions of teleportation. We identify a number of areas for future research.

As virtual reality (VR) headsets become more commercially accessible, a range of social platforms have been developed that exploit the immersive nature of these systems. There is a growing interest in using these platforms in social and work contexts, but relatively little work into examining the usability choices that have been made. We developed a usability inspection method based on cognitive walkthrough that we call guided group walkthrough. Guided group walkthrough is applied to existing social VR platforms by having a guide walk the participants through a series of abstract social tasks that are common across the platforms. Using this method we compared six social VR platforms for the Oculus Quest. After constructing an appropriate task hierarchy and walkthrough question structure for social VR, we ran several groups of participants through the walkthrough process. We undercover usability challenges that are common across the platforms, identify specific design considerations and comment on the utility of the walkthrough method in this situation.

“…As the name suggests, the hybrid technique is an ultimate approach to resolve the spatial consistency recovery problem by combining the first two techniques mentioned in Section 3.1 and 3.2. Similar to group teleportation [23], this technique allows the user to teleport the targeted virtual object and themself simultaneously to support a tangible interaction at a specific destination in the virtual world. However, their spatial relationship needs to be recomputed with regard to the spatial arrangement between the user and the physical prop (see Fig.…”

The application of virtual reality (VR) for everyday use is often limited due to the lack of tactile and kinesthetic feedback. To facilitate and expand the use of VR in daily life, it is possible to employ physical objects readily available at home as tangible objects to provide this missing feedback. For instance, a real chair can allow a user to sit within the virtual environment, even if the sitting place in the virtual world is not a chair. In home-based games, a real but not dangerous stick can provide the holding sensation of a virtual sword. These tracked objects in the real world can serve as a tangibility medium to their virtual counterparts, contributing to a higher sense of presence and immersion. However, such a solution relies on a consistent spatial relationship between the real and virtual space surrounding the user, which makes the basic use of virtual navigation techniques such as teleportation difficult. To allow the navigation on a large virtual environment while supporting a tangible interaction with real objects in a limited physical space at home, this paper explores three different teleportation techniques: to teleport the user, the object, or both of them to a new position accordingly while preserving the user and object's spatial relationship. All of these approaches enable tangible interaction when using a teleportation technique for navigation, but each one is more or less suitable in different situations of real/virtual spatial consistency.
