During the recent pandemic, critical decisions were taken by public healthcare officials by ie ving and analyzing data. Doing so in an immersive environment like virtual reality (VR) would have provided more context and aided with engagement and better performance. As a solution to this problem, an interactive 3D virtual reality data visualization tool is being developed by a team of Unreal developers, public-health domain experts, and user experience (UX) researchers at the Imaging Research Center, UMBC. This research aims to understand the interaction mechanisms that a novice user from the public health domain might face when interacting with an immersive data visualization tool. The results show that public policy and emergency health services workers found it beneficial to interact and find relationships between data in an immersive VR environment and were able to offer design recommendations for a more effective and engaging experience.

Researchers working in areas such as lexicography, translation studies, and computational linguistics, use a combination of automated and semi-automated tools to analyze the content of text corpora. Concordancing - or the arranging of passages of a textual corpus in alphabetical order according to user-defined keywords - is one of the oldest and still most widely used forms of text analysis. Concordance Mosaic is an interactive concordance visualization which emphasises quantitative information such as word frequency. While Concordance Mosaic is in active use by humanities scholars, no quantitative evaluation of the technique exists. In this paper, the Concordance Mosaic is quantitatively evaluated in comparison to a typical concordance browser. The comparison is evaluated using speed and accuracy on identified corpus analysis actions.

Patients are expected to manage their chronic conditions, but very few exercise regularly in addition to taking their medications. Therefore, we developed a 3-minute HMD VR program to educate patients about the importance of exercise. The control group (n = 30) received usual care, while the experimental group (n= 30) experienced virtual reality and assessed SSQ and exercise intention. No patients experienced VR sickness and the experimental group showed a statistically significant higher intention to exercise for diabetes management. Older adults found the VR experience exciting and novel. For diabetic foot experience, color change is enough to motivate them.

Virtual Reality (VR) can be found in many fields. A majority of the time this involves the use of Head-Mounted Displays (HMDs). Their alternatives, large-scale immersive 3D screens and CAVE systems, can also be found in research and offer researchers high visual quality and collaborative VR experiences. This report covers the operation and learnings from maintaining a visualization center with large-scale immersive installations over the course of ten years.

Photography in augmented reality can he challenging due to the restrictions of pre-defined settings. However, adjustable photography settings and real-time previews are significant for AR photographic creation as creators must adjust multiple camera properties to present unique visual effects. In this work, we designed an AR camera (ARCam) with various adjustable properties to give users a high degree of freedom for photographic art creation in real-time preview.
Traditional scientific visualization pipelines transfer entire data arrays from storage to client nodes for processing into displayable graphics objects. However, this full data transfer is often unnecessary, as many ...

In this paper, we present a software architecture and framework developed over the past decade to enable scalable and highly interactive visualizations for large datasets and display sizes. The framework integrates distributed data processing, data streaming, and dynamic scheduling to allow for view-dependent feature extraction and progressive data streaming. Additionally, the framework has been designed to support visualizations from local desktop workstations to large multi-display virtual environments.
