Force display system for realization of cut-in-feeling of virtual sheet object by scissors

A stereoscopic cutting of virtual object in a real space using a human binocular parallax is discussed. A scissors-type edged-tool with 2-degree of freedom is developed for the realization of reactive force feeling on the cutting into stereoscopically viewed virtual object. An image of sheet is given as a virtual object for cutting. The reactive force is provided for the tool, by which fingers obtain feeling of cutting according to given physical properties to the image. The stereoscopic cutting makes clear a trace of the cutting point of scissors characterized by a different color in a virtual object given as an image. This paper describes first the construction of a scissors-type edged-tool for cutting. Then, force display system is synthesized providing feeling of cutting of materials by the edged-tool according to their given properties
