Abstract:
Auditory display techniques can play a key role in the understanding of hidden patterns in large datasets. In this study, we investigated the role of sonification applied to an immersive 3D visualization of a complex network dataset. As a test case, we used a 3D interactive visualization of the so called, connectome of the human brain, in the immersive space called "eXperience Induction Machine (XIM)". We conducted an empirical validation where subjects were asked to perform a navigation task through the network and were subsequently tested for their understanding of the dataset. Our results showed that sonification provides a further layer of understanding of the dynamics of the network by enhancing the subjects' structural understanding of the data space.
