| Research Abstract |
A stereoscopic manipulating hardware system of 3D virtual objects in a real and a virtual space is proposed on the basis of a human binocular parallax. 3D image objects characterized by assumed physical properties of materials are cut by a stereoscopic virtual edged-tool given in a real and a virtual space that is operated in the same way of a master movement of a newly developed scissors-type hardware edged-tool. By manipulation of the hardware edged-tool, stereoscopic virtual objects can be cut into without any particular constraint in its operation. Then, an image-cutting force display system is developed which can provide an operator well attendance to the realistic operation of virtual objects with a smooth reactive feeling dependent on their given physical properties. Some essential techniques are described for the stereoscopic realization of 3D virtual materials and 3D virtual edged-tool, and also for the design of the hardware edged-tool in order to compose a force display system. The proposed force display system is confirmed a useful human interface and applied to the educational simulator of surgery with direct reactive feeling on fingers and visual recognition of its operation including spatial and structural understandings of virtual objects.
