Abstract
This paper proposes an intuitive interface system for designing 3D shapes in the physical location between a computer and its user This system allows the generation of a 3D shape using hand gestures combined with verbal expressions that attempt to represent a 3D shape. Current 3D modeling tools do not serve shape design well because they primarily use two dimensional pointing devices that are not intuitive in their use If we use a virtual environment as an arena for getting ideas about 3D shape design. we could intuitively describe 3D objects Our approach is to convert from gesture trajectory point position data to a generalized super-quadric function representation, and to utilize verbal expressions to constrain vibration modes of a generalized super-quadric function representation. We achieved such an interface system to integrate hand gestures and verbal expressions to represent a 3D shape
