There is a need for computer aided design tools that support rapid conceptual level design. In this paper we explore and evaluate how intuitive speech and multitouch input can be combined in a multimodal interface for conceptual 3D modeling. Our system, MozArt, is based on a user's innate abilities - speaking and touching, and has a toolbar/button-less interface for creating and interacting with computer graphics models. We briefly cover the hardware and software technology behind MozArt, and present a pilot study comparing our multimodal system with a conventional multitouch modeling interface with first time CAD users. While a larger study is required to obtain statistically significant comparison regarding efficiency and accuracy of the two interfaces, a majority of the participants preferred the multimodal interface over the multitouch. We summarize lessons learned and discuss directions for future research.
