Visualizing Plasma Physics Simulations in Immersive Environments
International Conference on Information Visualization Theory and Applications(2023)
摘要
Plasma physics simulations create complex datasets for which researchers need
state-of-the-art visualization tools to gain insights. These datasets are 3D in
nature but are commonly depicted and analyzed using 2D idioms displayed on 2D
screens. These offer limited understandability in a domain where spatial
awareness is key. Virtual reality (VR) can be used as an alternative to
conventional means for analyzing such datasets. VR has been known to improve
depth and spatial relationship perception, which are fundamental for obtaining
insights into 3D plasma morphology. Likewise, VR can potentially increase user
engagement by offering more immersive and enjoyable experiences. Methods This
study presents PlasmaVR, a proof-of-concept VR tool for visualizing datasets
resulting from plasma physics simulations. It enables immersive
multidimensional data visualization of particles, scalar, and vector fields and
uses a more natural interface. The study includes user evaluation with domain
experts where PlasmaVR was employed to assess the possible benefits of
immersive environments in plasma physics visualization. The experimental group
comprised five plasma physics researchers who were asked to perform tasks
designed to represent their typical analysis workflow. To assess the
suitability of the prototype for the different types of tasks, a set of
objective metrics, such as completion time and number of errors, were measured.
The prototype's usability was also evaluated using a standard System Usability
Survey questionnaire.
