The Effects of Virtual Reality on Motor Performance in the First Person Point of View

Previous research has shown that visualization is an effective method used to improve motor performance (Ridderinkhof, 2015) and that similar neural pathways are activated while visualizing and performing a task (Decety, 1989). More recent research has begun to look at whether virtual reality similarly improves motor performance (Bideau, 2004). The advantages of virtual reality include the ability to practice without physical exertion (Ridderinkhof, 2015) and a better cognitive understanding of complex tactics (Science-based cognitive assessment & training, 2019). In the current study, the effects of virtual reality and visualization on motor performance in sports is tested based on the success rate of being able to make free-throws between the Control, Visualization or Virtual Reality groups. I hypothesized that the Virtual Reality group will make more shots than the Visualization or the Control groups because of its more interactive ability. I also hypothesized that participants\u27 self-efficacy will increase after using virtual reality. The results of my research showed that there was no significant difference in shooting ability between groups. On the other hand, the participants in the Virtual Reality group found virtual reality to be significantly more useful than the Control group found counting backwards to be. Virtual reality was not significantly on any of the other self-efficacy questions. Future research should continue to examine the possible effects that virtual reality can have on motor performance as well as self-efficacy improvement

Point cloud data compression

The rapid growth in the popularity of Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) experiences have resulted in an exponential surge of three-dimensional data. Point clouds have emerged as a commonly employed representation for capturing and visualizing three-dimensional data in these environments. Consequently, there has been a substantial research effort dedicated to developing efficient compression algorithms for point cloud data. This Master's thesis aims to investigate the current state-of-the-art lossless point cloud geometry compression techniques, explore some of these techniques in more detail and then propose improvements and/or extensions to enhance them and provide directions for future work on this topic

A Method to Visualize Patient Flow Using Virtual Reality and Serious Gaming Techniques

This paper proposes a method to visualize Emergency Department patient flow data in a Virtual Reality (VR) Serious Game (SG) environment. Visualizing the patient flow data will allow patterns and trends that hospitals can use to reduce alternative level of care (ALC) days and increase the acute capacity of the hospital. The method proposes to use Unity to develop two VR visualisations of patient flow to a hospital ED such that hospital staff can determine which of the two visualizations will be the most usable, immersive, and playable. This paper also presents future work that will look at the whole system of a hospital using one years’ worth of patient flow data to develop a usable, immersive and playable Virtual Environment (VE)

3D MODELING AND VIRTUAL APPLICATIONS FOR THE VALORIZATION OF HISTORICAL HERITAGE

[EN] A large amount of 3D digital models, acquired with reality-based techniques or modelled with CAAD methods, are today part of archaeological studies. This new form of heritage documentation has deeply changed the traditional way of representing, studying and visualizing the remains of the past. At the same time, 3D digital documentation is rarely shared and easily accessible, so as the historical iconographic sources, text documents and other information used forinterpreting remains and for validating 3D reconstructions. This paper describes the first results of an interdisciplinary project of 3D documentation and valorization of historical heritage, carried out in the archaeological site of Pausilypon (Naples, Italy). The final aim is to realize an integrated virtual tour of the site, developed in Unity 3D, based on 3D surveying products. This tour proposes a new way of presenting and visualizing results of archaeological studies and 3D documentation, collecting and overlapping different types of data in a unique and interactive virtual environment. Besides 360° equi-rectangular panoramic image and 3D models, heterogeneous material will help users to understand the interpretative process followed for the hypothetical CAAD reconstruction. These results will be mainly shared via web, for a larger dissemination of the work and for supporting future research on the site. In addition, for promoting the knowledge of the archaeological remains, a simplified and immersive tour will be developed for Virtual Reality devices.Farella, E.; Menna, F.; Remondino, F.; Campi, M.

The Urban CoCreation Lab—An Integrated Platform for Remote and Simultaneous Collaborative Urban Planning and Design through Web-Based Desktop 3D Modeling, Head-Mounted Virtual Reality and Mobile Augmented Reality: Prototyping a Minimum Viable Product and Developing Specifications for a Minimum Marketable Product

Both policy and research highlight the importance of diverse stakeholder input in urban development processes but visualizing future built environments and creating two-way design communication for non-expert stakeholders are challenging. The present study develops an intuitive and simplified 3D modeling platform that integrates web-based desktop, virtual reality and mobile augmented reality technologies for remote simultaneous urban design collaboration. Through iterative prototyping, based on two series of workshops with stakeholders, the study resulted in such an integrated platform as a minimum viable product as well as specifications for a minimum marketable product to be used in real projects. Further study is required to evaluate the minimum level of detail in the 3D modeling necessary for good perception of scale and environmental impact simulation

A review of data visualization: opportunities in manufacturing sequence management.

Data visualization now benefits from developments in technologies that offer innovative ways of presenting complex data. Potentially these have widespread application in communicating the complex information domains typical of manufacturing sequence management environments for global enterprises. In this paper the authors review the visualization functionalities, techniques and applications reported in literature, map these to manufacturing sequence information presentation requirements and identify the opportunities available and likely development paths. Current leading-edge practice in dynamic updating and communication with suppliers is not being exploited in manufacturing sequence management; it could provide significant benefits to manufacturing business. In the context of global manufacturing operations and broad-based user communities with differing needs served by common data sets, tool functionality is generally ahead of user application

Application of serious games to sport, health and exercise

Use of interactive entertainment has been exponentially expanded since the last decade. Throughout this 10+ year evolution there has been a concern about turning entertainment properties into serious applications, a.k.a "Serious Games". In this article we present two set of Serious Game applications, an Environment Visualising game which focuses solely on applying serious games to elite Olympic sport and another set of serious games that incorporate an in house developed proprietary input system that can detect most of the human movements which focuses on applying serious games to health and exercise

Seeing the invisible: from imagined to virtual urban landscapes

Urban ecosystems consist of infrastructure features working together to provide services for inhabitants. Infrastructure functions akin to an ecosystem, having dynamic relationships and interdependencies. However, with age, urban infrastructure can deteriorate and stop functioning. Additional pressures on infrastructure include urbanizing populations and a changing climate that exposes vulnerabilities. To manage the urban infrastructure ecosystem in a modernizing world, urban planners need to integrate a coordinated management plan for these co-located and dependent infrastructure features. To implement such a management practice, an improved method for communicating how these infrastructure features interact is needed. This study aims to define urban infrastructure as a system, identify the systematic barriers preventing implementation of a more coordinated management model, and develop a virtual reality tool to provide visualization of the spatial system dynamics of urban infrastructure. Data was collected from a stakeholder workshop that highlighted a lack of appreciation for the system dynamics of urban infrastructure. An urban ecology VR model was created to highlight the interconnectedness of infrastructure features. VR proved to be useful for communicating spatial information to urban stakeholders about the complexities of infrastructure ecology and the interactions between infrastructure features.https://doi.org/10.1016/j.cities.2019.102559Published versio

Exploring the Design Space of Immersive Urban Analytics

Recent years have witnessed the rapid development and wide adoption of immersive head-mounted devices, such as HTC VIVE, Oculus Rift, and Microsoft HoloLens. These immersive devices have the potential to significantly extend the methodology of urban visual analytics by providing critical 3D context information and creating a sense of presence. In this paper, we propose an theoretical model to characterize the visualizations in immersive urban analytics. Further more, based on our comprehensive and concise model, we contribute a typology of combination methods of 2D and 3D visualizations that distinguish between linked views, embedded views, and mixed views. We also propose a supporting guideline to assist users in selecting a proper view under certain circumstances by considering visual geometry and spatial distribution of the 2D and 3D visualizations. Finally, based on existing works, possible future research opportunities are explored and discussed.Comment: 23 pages,11 figure
