Supplementary Material for "A Malleable Device with Applications to Sonification-based Data Exploration"

This article introduces a novel human computer interaction device, developed in the scope of a Master’s Thesis [1]. The device allows continuous localized interaction by providing a malleable interaction surface. Diverse multi-finger as well as multi-handed manipulations can be applied. Furthermore, the device acts as a tangible user interface object, integrated into a tangible computing framework called tDesk [2]. Software to convert the malleable element’s shape into an internal surface representation has been developed. Malleable interactions are applied to a new Model-based Sonification approach for exploratory data analysis. High-dimensional data are acoustically explored via their informative interaction sound in result to excitation.
