We discuss the disadvantages of the current design support systems that arise from a poor understanding of the human-cognitive characteristics, such as the reflective and experimental modes, and the selection of a suitable media for use in the creative design process. Then we demonstrate the current prototype system called "Godzilla" that supports the creative design especially for the car exterior designer. The designers can draw the concept image on a 2D pad (tablet with an LCD). When they grasp it and put it in midair, the shape of the 2D sketch is automatically recognized and appears as 3D sketch on a 3D pad (stereovision TV). They can sketch, modify, and observe from different viewpoints in both 2D and 3D. Note that 3D images are not displayed as a beautiful CG image, but a 3D sketch that consists of many 3D-cursive lines produced by mimicking the designer's pen touch in order to keep the designers in the reflective cognitive mode and to provide them with rich stimuli for their creative activities.
