Paper Abstract:	The paper presents multimodal interfaces for virtual prototyping of aesthetic products. Multimodal interfaces are based on multiple interaction modalities such as vision, haptic and sound that allow designers to create, evaluate and modify digital shapes of styling products in a natural and intuitive way. The aim of our research is to propose more user-centred modeling tools that exploit designers’ skills during the conceptual development of new products, and then enhance designers’ creativity. Specifically, the paper presents two systems that have been developed within the context of two EU funded research projects. The first system, named T’nD, is based on a haptic interface that closely resembles a physical rake: the designer can create a shape by physically manipulating the scraping tool for removing material from a virtual piece of clay. The second system, named SATIN, consists of a haptic strip that is inspired by the tape that designers usually place on physical prototypes for evaluating their characteristics and style lines: a force sensitive tangible strip is located in space in the position of a section (curve) of the simulated virtual object, 3D visualization of the shape is superimposed onto the physical strip by means of a stereoscopic display system, and sound is added for rendering the curve geometrical characteristics.
