Evaluating geometrical properties of virtual shapes using interactive sonification

This papers presents some of our research about the use of sound in a multimodal interface. The aim of this interface is to support product design, where the designer is able to physically interact with a virtual object. The requirements of the system include the interactive sonification of geometrical data relating to the virtual object. In this paper we present three alternative sonification approaches designed to satisfy this condition. We also outline a user evaluation strategy aimed at measuring the performance and added value of the different sonification approaches.
