Sonification Enhances Perception of Color Intensity

This poster presents an interactive sonification experiment, designed to evaluate possible benefits of sonification in information visual- ization. The aim of the present study was to explore the use of composed and deliberately designed musical sounds to enhance perception of color intensity in visual representations. It was hypoth- esized, that by using musical sounds for sonification perception of color intensity would be improved. In this evaluation, sonification was mapped to color intensity in visual representations, and the par- ticipants had to identify and mark the highest color intensity, as well as answer a questionnaire about their experience. Both quantitative and qualitative preliminary results suggest a benefit of sonification, and indicate that sonification is useful in data exploration.
