Immersive Visualization for Volumetric Data Analysis
|
|
Visualization of volumetric data is critical in a variety of application domains, such as medicine, geophysical exploration, and biomechanics. In this project we are studying if the use of displays with higher levels of fidelity can improve the analysis of these datasets. In particular, we are looking more closely into the effect of Field of Regard and Stereoscopy across different display platforms.
We performed a multi-site VR fidelity component experiment with 60 participants in collaboration with Brown University. Virginia Tech conducted the experiment in a 4 wall CAVE and in a HMD, while Brown performed the same experiment in another similar CAVE. |
Our results confirm the high-level results of our previous study. Higher fidelity settings for both, field of regard and head tracking significantly improve the performance of users in complex spatial data exploration tasks. However, we found differences in individual task performances between platforms. We are now performing additional studies to improve our understanding of the issue.
