abstract = {Personal computers and handheld devices provide keyboard shortcuts and swipe gestures to enable users to efficiently switch between applications, whereas today's virtual reality (VR) systems do not.  In this work, we present an exploratory study on user interface aspects to support efficient switching between worlds in VR. We created eight interfaces that afford previewing and selecting from the available virtual worlds, including methods using portals and worlds-in-miniature (WiMs). To evaluate these methods, we conducted a controlled within-subjects empirical experiment (N=22) where participants frequently transitioned between six different environments to complete an object collection task. Our quantitative and qualitative results show that WiMs supported rapid acquisition of high-level spatial information while searching and were deemed most efficient by participants while portals provided fast pre-orientation. Finally, we present insights into the applicability, usability, and effectiveness of the VR world switching methods we explored, and provide recommendations for their application and future context/world switching techniques and interfaces.},

abstract = {Virtual reality (VR) experiences often rely on multisensory cues and realistic interactions to support convincing interpretations of virtual events and agents. This study examines how two factors, real-world priming and multisensory feedback, shape users’ perceptions of a virtual drone in a mixed-reality simulation. We conducted a mixed-design experiment where participants experienced either a physical drone flyover or no physical drone encounter, followed by audiovisual and multisensory drone flyovers in VR. Multisensory feedback increased co-presence and perceived realism specifically for participants who had encountered the real drone. In contrast, neither manipulation significantly affected standard presence measures. These findings highlight distinctions among presence-related constructs and suggest that recent real-world experiences can make certain multisensory cues be perceived as more realistic, even when they do not increase presence itself.},

Simulating AR cues within virtual reality (VR) enables controlled manipulation and measurement of these factors while preserving immersive viewing conditions. This work presents a perception-driven methodology for evaluating AR cue visibility that combines simulated AR cues in VR, high resolution stereoscopic 360◦ video, and continuous psychophysics. Using this methodology, tracking-based performance data provide a continuous behavioral measure of visibility in complex scenes. Multiple analysis approaches are examined to support interpretation of tracking-based measures of perceptual performance in visually complex scenes.

abstract = {Teleportation is one of the most widely used locomotion techniques in virtual reality (VR) because it is efficient, minimizes motion sickness, and enables large-scale spatial traversal with minimal effort. However, research on the Doorway Effect shows that spatial transitions can impair memory of information encountered just before the transition. Event Segmentation Theory (EST) explains this by proposing that salient changes disrupt a person’s working memory representation, causing recently encoded information to be replaced and reducing its availability for retrieval. By extension, the design of spatial transitions in VR may influence whether memory is disrupted or preserved, which could be a consideration in applied contexts such as education and training. One way to mitigate such impairment is to provide predictive cues about the upcoming change to reduce disruption. In VR, this can be implemented through teleportation previews, which give users a glimpse of the destination before arrival. In this experiment, we adapted the Doorway Effect paradigm to examine how two teleportation design factors — preview availability and environmental change — affect memory. Using a within-subjects 2 × 2 design (N = 27), participants studied a set of 3D objects, then teleported either within the same environment or into a different one, with or without a preview of the destination. After each transition, they completed a visual recognition task. Results showed two key findings: (1) without previews, recognition declined when teleporting into a different environment compared to remaining in the same one, and (2) when transitioning between different environments, providing a preview improved recognition relative to no preview. Together, these results indicate that both the distinctiveness of environments and the availability of previews shape memory during VR transitions. We discuss how these findings align with EST, highlight the cognitive consequences of teleportation design, and provide guidance for designing transitions that better support memory in applied contexts such as education and training.},

abstract = {Teleportation has become a popular locomotion method for virtual reality due to lesser demands on physical space and decreased levels of motion sickness compared to other methods. However, prior work has shown that these advantages come at the cost of impaired spatial perception and awareness, the extent to which is still largely unknown. In this work, we present a within-subjects study (N = 29) that explores the effects of teleportation on spatial perception by investigating how much humans can be unknowingly displaced relative to their intended destination during teleportation. After teleporting to the specified location, participants indicated the direction and magnitude (small, medium, large) of the perceived shift or rotation. Displacement from the target happened either as a translation in the forward- or strafe-axis, or a rotation about the up-axis at the intended target. Each displacement condition included eleven offsets that were repeated six times. Our results indicate points of subjective equality, which show a significant perceptual shift along the forward-direction, as well as detection thresholds, which indicate a comparatively wide range in which humans are unable to detect induced shifts. Furthermore, our results show that even if humans are able to detect these shifts, larger ones can be introduced before their magnitudes are rated as medium or large, which provides ample opportunities for interface designers who want to leverage these results in virtual reality.},

This paper presents a novel technique for automatic perspective alignment in collaborative MR involving co-located interaction centered around a shared virtual object. To align one user’s perspective on the object with a collaborator’s, a local copy of the object and any other virtual elements that reference it (e.g., the collaborator’s hands) are dynamically transformed. The technique does not require virtual travel and preserves face-to-face interaction. We created a prototype application to demonstrate our technique and present an evaluation methodology for related MR collaboration and perspective alignment scenarios.},

We conducted a within- and between-subjects evaluation with 12 participant pairs to examine the differences between these symmetric and asymmetric presentation modalities.

abstract = {Subjective measures, such as the Simulator Sickness Questionnaire (SSQ), Fast Motion Sickness Questionnaire (FMS), and discomfort scores, are widely used to assess cybersickness, but they often interrupt the user experience and are prone to bias. To overcome these limitations, researchers have also investigated objective indicators, though some approaches, such as using physiological data, can be cumbersome and impractical. Based on the loss of complexity hypothesis, which suggests that certain conditions, such as disease or aging, can produce a reduction of complexity in physiological system dynamics, we conducted an initial investigation of the relationship between movement complexity and cybersickness. We analyzed motion tracking collected from two previous cybersickness studies using the d95 score, a complexity metric derived using principal component analysis. The results revealed a systematic relationship between movement complexity and cybersickness across both experiments. Higher discomfort scores were associated with a reduction in complexity, thereby supporting the loss of complexity hypothesis. Furthermore, the 9-DOF complexity measure, which includes both physical head movement and virtual camera motion, was a more sensitive indicator than the 6-DOF measure computed from physical movements alone. These initial findings suggest that movement complexity may be a useful objective indicator for future cybersickness research.},

abstract = {Over the past decades there has been extensive research investigating the trade-offs between various Virtual Reality (VR) locomotion techniques. One of the most highly researched techniques is teleportation, due to its ability to quickly traverse large virtual spaces even in limited physical tracking spaces. The majority of teleportation research has been focused on its effects on spatial cognition, such as spatial understanding and retention. However, relatively little is known about whether the use of teleportation in immersive learning experiences can effect the acquisition of semantic knowledge — our knowledge about facts, concepts, and ideas — which is essential for long-term learning. In this paper we present a human-subjects study to investigate the effects of teleportation compared to natural walking on the retention of semantic information about artifacts in a virtual museum. Participants visited unique 3D artifacts accompanied by audio clips and artifact names. Our results show that participants reached the same semantic memory performance with both locomotion techniques but with different behaviors, self-assessed performance, and preference. In particular, participants subjectively indicated that they felt that they recalled more semantic memory with walking than teleportation. However, objectively, they spent more time with the artifacts while walking, meaning that they learnt less per a set amount of time than with teleportation. We discuss the relationships, implications, and guidelines for VR experiences designed to help users acquire new knowledge.},

abstract = {In most cases, retaining memories of things we have experienced in the past is desirable, but in some cases, we want to clear our minds so that we may focus completely on subsequent activities. When someone switches from one task to another, they commonly incur some “cognitive residue” where some of their cognitive resources such as working memory and attention remain devoted to their previous task even after they try to switch their focus to their new task. This residue could have a negative impact on their performance in the next task, and in such circumstances, it is important to reduce that residue. In this paper, we explore the concept of cognitive residue in the context of switching between virtual reality (VR) environments. We conducted a human-subject experiment (N=24) with a spatial recall task to investigate how different visual transitions might reduce participants’ spatial cognitive residue. In this instance, more errors on the recall task corresponds to less spatial cognitive residue. We found that transitions that lasted one minute successfully reduced spatial cognitive residue: they significantly reduced participants’ abilities to recall the positions of objects in their previous VE compared to an instantaneous cut transition. Additionally, for transitions that showed a nature scene, greater head movement significantly correlated with more spatial memory errors (i.e., less spatial cognitive residue). We discuss how these findings can be applied to support users transitioning between virtual tasks and environments in VR task switching scenarios.},
