1	Efektivní využití omezeného herního prostoru / Effective Use of Limited Game Space Brestič, Tomáš January 2018 (has links) Current generation of consumer electronics products for virtual reality (VR) allows to track user motion in physical play area which can be converted into a corresponding change of their position in a virtual environment. There are, however, some potential pitfalls with using this approach as the main method of user motion in the virtual space. Therefore, vast majority of contemporary applications is based on different methods that do not take advantage of the available play area and the possibilities of the input devices in their entirity. The main goal of this thesis is to propose and demonstrate a feasible way of implementation allowing the use of available physical space and to try to evaluate whether basing the user motion in an application on the described approach can result in an increase of user interest, attract more users and offer them better experience, and whether it therefore can be profitable in spite of all the related disadvantages.
2	ManiLoco: A Locomotion Method to Aid Concurrent Object Manipulation in Virtual Reality Dayu Wan (13104111) 15 July 2022 (has links) <p>In Virtual Reality (VR), users often need to explore a large virtual space within a limited physical space. However, as one of the most popular and commonly-used methods for such room-scale problems, teleport always relies on hand-based controllers. In applications that require consistent hand interaction, such teleport methods may conflict with the users' hand operation, and make them uncomfortable, thus affecting their experience. </p> <p>To alleviate these limitations, this research designs and implements a new interactive object-based VR locomotion method, ManiLoco, as an eye- and foot-based low-cost method. This research also evaluates ManiLoco and compares it with state-of-the-art Point & Teleport and Gaze Teleport methods in a within-subject experiment with 14 participants.</p> <p>The results confirm the viability of the method and its possibility in such applications. ManiLoco makes the users feel much more comfortable with their hands and focus more on the hand interaction in the application while maintaining efficiency and presence. Further, the users' trajectory maps indicate that ManiLoco, despite the introduction of walking, can be applicable to room-scale tracking space. Finally, as a locomotion method only relied on VR head-mounted display (HMD) and software detection, ManiLoco can be easily applied to any VR applications as a plugin.</p> Virtual and mixed reality Virtual Reality Locomotion Object Manipulation Room-Scale VR
3	Implementation and Analysis of Co-Located Virtual Reality for Scientific Data Visualization Jordan M McGraw (8803076) 07 May 2020 (has links) <div>Advancements in virtual reality (VR) technologies have led to overwhelming critique and acclaim in recent years. Academic researchers have already begun to take advantage of these immersive technologies across all manner of settings. Using immersive technologies, educators are able to more easily interpret complex information with students and colleagues. Despite the advantages these technologies bring, some drawbacks still remain. One particular drawback is the difficulty of engaging in immersive environments with others in a shared physical space (i.e., with a shared virtual environment). A common strategy for improving collaborative data exploration has been to use technological substitutions to make distant users feel they are collaborating in the same space. This research, however, is focused on how virtual reality can be used to build upon real-world interactions which take place in the same physical space (i.e., collaborative, co-located, multi-user virtual reality).</div><div><br></div><div>In this study we address two primary dimensions of collaborative data visualization and analysis as follows: [1] we detail the implementation of a novel co-located VR hardware and software system, [2] we conduct a formal user experience study of the novel system using the NASA Task Load Index (Hart, 1986) and introduce the Modified User Experience Inventory, a new user study inventory based upon the Unified User Experience Inventory, (Tcha-Tokey, Christmann, Loup-Escande, Richir, 2016) to empirically observe the dependent measures of Workload, Presence, Engagement, Consequence, and Immersion. A total of 77 participants volunteered to join a demonstration of this technology at Purdue University. In groups ranging from two to four, participants shared a co-located virtual environment built to visualize point cloud measurements of exploded supernovae. This study is not experimental but observational. We found there to be moderately high levels of user experience and moderate levels of workload demand in our results. We describe the implementation of the software platform and present user reactions to the technology that was created. These are described in detail within this manuscript.</div> Software Engineering Computer Software Computer Graphics Simulation and Modelling Virtual Reality and Related Simulation Mobile Technologies Networking and Communications Computer-Human Interaction Collaborative Virtual Reality Virtual Reality Collaborative Virtual Reality Networking Networked VR Mulitplayer Multiplayer VR Data Visualization Data Exploration Head Mounted Display Cyberspace Augmented Reality Emerging Technologies Consumer Devices Virtual Environment Virtual Aesthetics Collaborative VR Simulation Training Simulation and Training Colocated Colocated Virtual Environment Immersive Media Immersive Technology Collaborative Tools Educational Virtual Environment Point Cloud Representations Isosurface Representations Mesh Smoothng Supernova Supernovae Supernova Remnant Modeling Astronomy and Astrophysics Cassiopeia N132D E0102 Crab Nebula CAVE CAVE Theater Mobile VR Virtual Classrooms STEM Workload Workload Assessment Tool Presence Engagement Immersion Experience Consequence Simulator sickness Simulator Sickness Questionnaire NASA TLX NASA Task Load Index Unified User Experience Quesionnaire Modified User Experience Questionnaire Oculus Oculus Go Oculus Quest Novel Solutions Optitrack Motive Motion Capture Mocap User Experience Unity3D Game Engine Lidgren Room Scale VR Hall Scale VR Co-location Colocation Virtual Training Collaborative Virtual Environments Shared Virtual Environments Collaboration Whiteboard Mobile Virtual Reality VR HMD LAN UX CSCL UXQ TLX AR VE CVE 3D UI EVE
