ABSTRACT
In this paper, we introduce an interactive application for planar curve design in a real world based on spatial augmented reality (SAR). The key component is a projector-camera unit that recognizes physical control objects (i.e., key points of an intended curve) using a camera and displays a design result (i.e., a B-spline curve) directly on the real world surface using a projector. Usually, geometric design is performed with the aid of CAD software and traditional user interfaces of a computer system. The main contribution of this paper is application of spatial augmented reality techniques in the domain of computer-aided geometric design (CAGD) for more tangible and intuitive interaction in a real world. We describe the feature of the prototype system and demonstrate the working application with examples.
