title = {Design and Deployment of Convergent XR Experiences},
abstract = {This dissertation explores the development of a convergent extended reality (XR) space through several projects spanning multiple domains, including engineering education, scientific visualization, social virtual reality (VR), health, and productivity. The work represents a shift from developing single-use research projects to creating a broader framework of applications with real-world value beyond basic scientific research goals. Each user study detailed in this dissertation builds upon previous work, contributing to the core technologies of a single monolithic social VR space known as conVRged.The first demonstration of this framework involved developing a novel immersive collaborative land surveying experience. A user study with 85 participants evaluated the VR experience's effectiveness in training the use of surveying equipment, which is otherwise expensive and subject to weather conditions. The study found promising results for using this system in engineering curricula, with high levels of student engagement and enthusiasm. This project also developed foundational technologies for the social VR space used in subsequent projects.Next, a scientific visualization tool was developed to allow users to visualize and interact with large-scale point clouds in VR. The evaluation of this tool compared novel selection techniques in both VR and desktop environments, demonstrating relative advantages for each. The advanced rendering techniques developed for this project were integrated into conVRged, strengthening the productivity use case for the space.A third project analyzed a core component of each previous project, as well as many larger VR experiences — locomotion. A user study quantified the advantages of techniques used in our previous work and compared them to novel techniques built for a hand-tracked system. This study also demonstrated the effectiveness of conducting a study in a multi-purpose VR world rather than a single-use system.Finally, a discussion of the individual tools and development practices highlights the lessons learned and design decisions that led to the creation of a cohesive and valuable collection of VR technologies. This work underscores the convergence of a wide array of technologies that have enabled and continue to enable the use of conVRged for diverse research goals in the XR space.},

abstract = {Locomotion systems that allow the user to interact with large virtual spaces require precise input, competing with the same inputs available for performing a task in the virtual world. Despite extensive research on hand tracking input modalities, there is a lack of a widely adopted mechanism that offers general-purpose, high-precision locomotion across various applications. This research aims to address this gap by proposing a design that combines teleportation with a grab-pull locomotion scheme to bridge the divide between long-distance and high-precision locomotion in both a tracked-controller and free-hand environment. The implementation details for both tracked controller and tracked hand environments are presented and evaluated through a user study. The study findings indicate that each locomotion mechanism holds value for different tasks, with grab-pull providing more benefit in scenarios where smaller, more precise positioning is required. As found in prior research, controller tracking was found to be faster than hand tracking, but all participants were able to successfully use the locomotion system with both interfaces.},
