In this project we present a new approach for manually exploring 2D data by using interactive sonification and tangible active objects (TAOs), capable to move autonomously on the desk. As application we enable visually impaired people to explore 2D scatter plots audio-haptically. Specifically, TAOs represent graspable interaction probes that move autonomously towards the center of clusters in the scatter plot. When moved by the user they represent higher local density at their location as higher pitched sound, when released they trigger a spatial scan (data sonogram) sonification before they home to their initial location.
