Redirected Walking (RDW) shrinks large virtual environments to fit small physical tracking spaces while supporting natural locomotion. Particularly in predictive RDW, one of the core concepts of RDW, algorithms rely on predicting users' future paths to adjust the induced redirection, which manipulates users' perception to deviate their physical paths from the intended virtual paths. Current path predictions either assume drastic simplifications or build on complex human locomotion models, which are inappropriate for real-time planning and thus not usable for RDW. Further, adapting existing predictive RDW algorithms to unconstrained open space exponentially increases their computational complexity, so that they are not applicable in real-time. In this work-in-progress paper, we discuss the currently prevalent issues of path prediction in RDW and propose simple yet flexible path prediction models that support dynamic virtual open spaces. Our proposed prediction models consist of two shapes: a drop shape represented by the lemniscate of Bernoulli and a sector shape. They define an area, in which linear and clothoidic walking trajectories will be investigated.

This paper proposes a method using only RGB information from multiple captured panoramas to provide an immersive observing experience for real scenes. We generated an omnidirectional neural radiance field by adopting the Fibonacci sphere model for sampling rays and several optimized positional encoding approaches. We tested our method on synthetic and real scenes and achieved satisfying empirical performance. Our result makes the immersive continuous free-viewpoint experience possible.

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.

Virtual Reality (VR) is one of the new educational technologies that has an imperative importance due to the possibilities that it offers, such as bringing hands-on experiences for learning physics phenomena. This demo report is a serious-game, based on VR, and focused on teaching and learning of specific concepts of kinematics. The game is intended to deliver an immersive experience in which the student has an active role and whose game design includes theoretical concepts to maintain engagement throughout the tasks.

The growth of the wind energy industry in the United States has been remarkable; however, despite its significance and installation capacity, wind energy investments such as wind turbines and wind farms involve various safety risks. To increase awareness of construction workers regarding hazards associated, one needs to develop engaging training programs. Therefore, to address this emergent need, we develop a realistic simulation of the wind tower construction process in an immersive virtual reality environment aiming at informing workers of the general safety and health hazards associated with the critical processes used in constructing, maintaining, and demolishing wind towers.

We report on designing a sound synthesis interface for a head-mounted augmented reality environment. The increased accessibility of augmented reality (AR) devices has incentivised the exploration of sound applications for music performance in computer music and other relevant communities. However, interaction affordances vary based on the specific AR device and thus implies different design considerations. In this poster, we present different interface prototypes for a frequency modulation synthesis system in the Microsoft HoloLens 2 and report our insights during the process of their developments.

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.

In this work, we propose a multi-modal approach to manipulate smart home devices in a smart home environment simulated in virtual reality (VR). We determine the user's target device and the desired action by their utterance, spatial information (gestures, positions, etc.), or a combination of the two. Since the information contained in the user's utterance and the spatial information can be disjoint or complementary to each other, we process the two sources of information in parallel using our array of machine learning models. We use ensemble modeling to aggregate the results of these models and enhance the quality of our final prediction results. We present our preliminary architecture, models, and findings.
