User evaluations of interactive multimodal data presentation

A set of user evaluation studies were performed to test hypotheses about the efficacy and value of the use of sonification by itself and together with visualization to improve the process of interactive data exploration. Our results show that, in some cases, sonification yielded more accurate analysis results than visualization, and when combined with visualization, yield much better results than either one (visualization or sonification) yielded separately. That supports sonification as a valuable and promising tool that should be further studied as a complement to visualization systems.
