This study aims to investigate the immediate and retained effects of one-time virtual reality (VR) exposure on intercultural sensitivity (IS) and identify the contributing factors. Three virtual scenarios about the ethnic minorities in Hong Kong were created for the empirical study. The longitudinal results involving 30 participants (15M 15F) showed that both the immediate and retained effects of the one-time VR exposure on IS were significant. Moreover, linear growth curve models suggested that among the female participants, presence and emotional empathy were closely associated with the change of IS over time, but this relation was not significant among the males.

According to social psychological models, the presence of another person or even a virtual character in stressful situations can have stress-reducing effects. Thereby, the outcome can depend on the congruency between one's mood and the perceived mood of the other person. This dependence guides the design of VR applications for stress reduction, which use different virtual companion designs depending on the emotional state of individual users. This paper describes an ongoing design and development process towards such an emotionally supportive companion and shares initial results con-cerning the perception and stress-reducing effects of positively- and negatively-minded companions.

Extended reality (XR), including virtual reality (VR) and augmented reality (AR) may overcome barriers to training healthcare workers, such as resource constraints. However, the effectiveness of XR training is disputed and not well understood. Our realist review explores how, for whom and in what contexts AR and VR training 'works' in upskilling healthcare workers. Eighty papers informed our program theory, while 46 empirical studies tested/refined it. We conclude that XR triggers perceptions of realism and deep immersion, and enables visualization, interactive learning, enhancement of skills and repeated practice within a safe learning environment, consequently bettering skills, learning/knowledge and learner satisfaction.

Direct volume rendering (DVR) is a standard technique for visualizing scientific volumetric data in three-dimension (3D). Utilizing current mixed reality head-mounted displays (MR-HMDs), the DVR can be displayed as a 3D hologram that can be superimposed on the original ‘physical’ object, offering supplementary x-ray visions showing its interior features. These MR-MHDs are stimulating innovations in a range of scientific application fields, yet their capabilities on DVR have yet to be thoroughly investigated. In this study, we explore a key requirement of rendering latency capability for MR - HMDs by proposing a benchmark application with 5 volumes and 30 rendering parameter variations.

It is crucial to prevent safety accidents for human-robot collaboration. This study proposes an extended reality (XR) approach to safe HRC by calculating the minimum distance between the human operator and robot in real time. The proposed approach scans the real environment with multiple sensors and constructs its virtual space in XR. The virtual robot is synchronized with the real robot by matching the point cloud of real environment with that of the virtual robot. This system can effectively provide task assistance and safety information to the user wearing an XR device.

Real-time 3D reconstruction using multiple RGBD cameras and their online transmission facilitates the adoption of mixed reality telepresence. However, such a system can only cover a limited volume, and increasing the number of RGBD cameras is unfeasible due to setup complexity and space constraints. To address this issue, we present the concept of Dynamic 3D View Sharing, which complements the views of a 3D reconstruction system by the dynamic view of the user's HMD. Here, we present a markerless calibration method integrating these two seamlessly into the mixed reality telepresence systems without disrupting the current workflow.

This paper describes a system that provides general head-worn outdoor augmented reality (AR) capability for the user inside a moving vehicle. Our system follows the concept of combining pose estimation from both vehicle navigation system and wearable sensors to address the failure of commercial AR devices inside a moving vehicle. We continuously match natural visual features from the camera against a prebuilt database of interior vehicle scenes. To improve the robustness in a moving vehicle with other passengers, a human detection module is adapted to filter out people from the camera scene. Experiments demonstrate the effectiveness of the proposed solution.

Behavior-based authentication methods are actively being developed for XR. In particular, gaze-based methods promise continuous au-thentication of remote users. However, gaze behavior depends on the task being performed. Identification rate is typically highest when comparing data from the same task. In this study, we compared authentication performance using VR gaze data during random dot viewing, 360-degree image viewing, and a nuclear training simu-lation. We found that within-task authentication performed best for image viewing (72%). The implication for practitioners is to integrate image viewing into a VR workflow to collect gaze data that is viable for authentication.
