Case-based Exploration of the Augmented Prototyping Dialogue to Support Design

The concept of Augmented Prototyping combines Rapid Prototyping techniques (e.g. Stereolithography, CNC milling) with Augmented Reality systems. The aim is to establish a high sense of engagement in the design process, supporting both exploration and presentation. In this paper, two Augmented Prototyping Systems are discussed: kitchen layout and a nightclub interior. These differ in a variety of aspects (most notably scale), yet are representative of typical prototyping scenarios. Our objective is to identify key issues and guidelines of the multimodal design interface for Augmented Prototyping systems. The systems were evaluated by senior design students, resulting in positive potential for exploration and evaluation tasks. A prototyping platform called WARP and four categories of design support are introduced. Future versions of our systems will support better tracking technologies and more elaborate simulation means.
