High-Performance Computer (HPC) is computer systems that are built to be able to solve computational loads. HPC can provide a high-performance technology and short the computing processes timing. This technology was often used in large-scale industries and several activities that require high-level computing, such as rendering virtual reality technology. In this research, we provide Tawaf’s Virtual Reality with 1000 of Pilgrims and realistic surroundings of Masjidil-Haram as the interactive and immersive simulation technology by imitating them with 3D models. Thus, the main purpose of this study is to calculate and to understand the processing time of its Virtual Reality with the implementation of tawaf activities using various platforms; such as computer and Android smartphone. The results showed that the outer-line or outer rotation of Kaa’bah mostly consumes minimum times although he must pass the longer distance than the closer one.  It happened because the agent with the closer area to Kaabah is facing the crowded peoples. It means an obstacle has the more impact than the distances in this case.

Goalkeepers play a very specific and crucial role in water polo. They rely on advanced perceptual–cognitive (P–C) skills to make fast and accurate decisions. However, their daily training environment often lacks stimulation and representativeness of game demands. This was exacerbated by the COVID-19 pandemic, where noncontact practices became the “new normal.” In the Canadian Women’s National Team preparation for the 2020 Olympics, goalkeepers’ P–C training was made a priority. Led by the team’s mental performance consultant and experts from transdisciplinary fields, the initiative began with an evaluation of a broad range of P–C skills in goalkeepers. Leading up to the Olympics, a series of P–C activities (i.e., anticipatory training using video occlusion, eye–hand coordination, and visuomotor drills) were adopted based on ecological dynamics principles. Virtual reality technology and constraints-focused tools were used to enrich and diversify the goalkeepers’ daily trainings environment. This case study reports the evaluation of P–C skills, the context, and the way in which the P–C activities were implemented, as well as their holistic impact on goalkeepers. Reflections and limitations are also shared to encourage interdisciplinary efforts in sport psychology and increase awareness among mental performance consultants about the importance of psycho-perceptual-motor skill training for mental performance.

The Relationship

As the physical environment of urban underground streets space is continuously perfect, people start to anticipate that underground streets with negative impression could satisfy their psychological comfort appeal as traditional ground streets do. Streets’ pavement is of great significance in creating humanized and comfortable underground spatial atmosphere, and different ground pavements of underground commercial streets display different visual comfort effects. We conducted field investigations of a dozen typical underground streets in eight big cities in China with 42 test samples, and this research obtained the pavement elements’ data of underground commercial streets, built virtual 3D scenes based on orthogonal analysis and virtual reality technology of computer vision, acquired the psychological data of spatial experience through virtual reality test, and analyzed the relationship between six elements (glossiness, roughness, color, dimension, pattern, and collage of ground pavement in underground commercial streets) and spatial visual comfort based on quantitative analysis of experimental data. Results show that, “Cold–hot sensation”, “Glossiness”, and “Collage ordered degree” are chief elements for underground commercial streets’ pavement design. The pavement design featured with neutral color, medium- and large-scale and ordered collage form are the design preference and emphasis for underground commercial streets. Neutral color of underground commercial streets pavement may have a great influence on the recognition of pavement glossiness.

Real-world navigation requires movement of the body through space, producing a continuous stream of visual and self-motion signals, including proprioceptive, vestibular, and motor efference cues. These multimodal cues are integrated to form a spatial cognitive map, an abstract, amodal representation of the environment. How the brain combines these disparate inputs and the relative importance of these inputs to cognitive map formation and recall are key unresolved questions in cognitive neuroscience. Recent advances in virtual reality technology allow participants to experience body-based cues when virtually navigating, and thus it is now possible to consider these issues in new detail. Here, we discuss a recent publication that addresses some of these issues (D. J. Huffman and A. D. Ekstrom. A modality-independent network underlies the retrieval of large-scale spatial environments in the human brain. Neuron, 104, 611–622, 2019). In doing so, we also review recent progress in the study of human spatial cognition and raise several questions that might be addressed in future studies.

Moving our body through space is fundamental to human navigation; however, technical and physical limitations have hindered our ability to study the role of these body-based cues experimentally. We recently designed an experiment using novel immersive virtual-reality technology, which allowed us to tightly control the availability of body-based cues to determine how these cues influence human spatial memory [Huffman, D. J., & Ekstrom, A. D. A modality-independent network underlies the retrieval of large-scale spatial environments in the human brain. Neuron, 104, 611–622, 2019]. Our analysis of behavior and fMRI data revealed a similar pattern of results across a range of body-based cues conditions, thus suggesting that participants likely relied primarily on vision to form and retrieve abstract, holistic representations of the large-scale environments in our experiment. We ended our paper by discussing a number of caveats and future directions for research on the role of body-based cues in human spatial memory. Here, we reiterate and expand on this discussion, and we use a commentary in this issue by A. Steel, C. E. Robertson, and J. S. Taube (Current promises and limitations of combined virtual reality and functional magnetic resonance imaging research in humans: A commentary on Huffman and Ekstrom (2019). Journal of Cognitive Neuroscience, 2020) as a helpful discussion point regarding some of the questions that we think will be the most interesting in the coming years. We highlight the exciting possibility of taking a more naturalistic approach to study the behavior, cognition, and neuroscience of navigation. Moreover, we share the hope that researchers who study navigation in humans and nonhuman animals will synergize to provide more rapid advancements in our understanding of cognition and the brain.

Flow Simulations

The visualization of computational simulations of complex physical problems using virtual reality technology is demonstrated in this study. A general-purpose computational steering system (POSSE) which can be coupled to any C/C++ simulation code, has been developed and tested with a 3-D parallel Navier-Stokes flow solver (PUMA2) [1]. In addition, the visualizations can be displayed using virtual reality facilities (such as CAVEs and RAVEs) to better understand the 3-D nature of the flowfields. The simulations can be run on parallel computers such as Beowulf clusters, while the visualization is performed on other computers, through a client-server approach. A key advantage of our system is its scalability. Visualization primitives are generated on the parallel computer. This is essential for large-scale simulations, since it is often not possible to post-process the entire flowfield on a single computer due to memory and speed constraints. Example applications of time-dependent and three-dimensional computational flow simulations performed at Penn-State are presented to show the usefulness of POSSE and virtual reality systems. The examples include CFD predictions for unsteady simulations of a helicopter rotor, unsteady ship airwake simulations, helicopter tail fan-in-fin flow simulations and simulations of time-accurate flow and noise due to a landing gear.
