Motivation and Problem
Problem: Effectiveness (time) of layout flexibility for
volume visualization
Hypothesis: Constrained multiple-views best for time-
variant data

Conclusions
Time-invariant:
NO effect on accuracy, speed, performance
Time-variant:
Multiple Views > Single View
![Page 20: Layout of Multiple Views for Volume Visualization: A User Study Daniel Lewis, Steve Haroz, Kwan-Liu Ma University of California, Davis](https://reader035.vdocuments.site/reader035/viewer/2022062517/56649eec5503460f94bfddf4/html5/thumbnails/20.jpg)

Conclusions
Hypothesis NOT supported
Layout flexibility does NOT effect performance
![Page 21: Layout of Multiple Views for Volume Visualization: A User Study Daniel Lewis, Steve Haroz, Kwan-Liu Ma University of California, Davis](https://reader035.vdocuments.site/reader035/viewer/2022062517/56649eec5503460f94bfddf4/html5/thumbnails/21.jpg)
Discussion and Future Works
Benefit of flexibility offsets time spent
Future Works
•More test subjects
•More tests with specialist
•More and varied layouts
