Natural hand writing in unstable 3D space with artificial surface

Abstract

Conventional 3D design systems enable us to make a primitive geometrical figure. That system is useful for structural design. But they are not useful for conceptual design. This paper proposes new and natural design system that fits for conceptual design in 3D space. This system always represents the "hand-writing sketch" in midair by the crystal shutter glasses, and produces the virtual tactile plain in 3D space such as real paper surface by a force feedback device.
