Abstract
In order to respond to consumer needs, it is necessary to develop the product of a high function for a short period of time, and increase in efficiency of development is desired. However, in the product development environment which uses a present three dimensional CAD system, since the holding-ness and the operativity of a handy information device cannot be evaluated correctly, a majority of trial productions, evaluations, and corrections need to be repeated, and it prevents from efficient product development. So, the goal of this research is to realize an augmented reality system for efficient product development of a handy information device. Using this system, the user grips the tangible device which tactually displays the diagrammic shape of the handy information device under designing. At the same time, the user watches the visual seen which is generated from the real image of the hand of griping the interface is superimposed on the minute shading image from the 3D-CAD model synchronized with the device. Then the user is able to feel to directly operate the device in designing. The configuration of the sytem is decsribed in this reoprt.
