VR Data Visualization: Useful For Multidimensional Data?
VR data visualization is great for multidimensional data analysis; VR allows you to view the data in ‘multiple dimensions’ From taking a guess, we can assume that this relates to VR’s ability to display data in 3D. So the additional dimension here would be depth (z-axis). But because we don’t perceive depth well, due the distortions and other issues that can occur, would having an extra dimension be of much benefit? Also, 2D charts can already visualise multidimensional and multivariate data with Bubble Charts, Chernoff Faces, Parallel Coordinates Plots, Radar Charts. So what would VR do better? If VR is capable of displaying more than one extra dimension, how would this be beneficial? In Stephen Few’s critical post on VR data visualization, he makes the point that: […]And let us not forget that we can only hold from three to four chunks of visual information in working memory at once, so even if VR could add many more dimensions of data in some way, it would be of no use to our limited brains if we weren’t able to process all of those dimensions simultaneously.
