A recent manifestation of the new paradigm regarding the relationship between humans and computers is called artificial reality, virtual reality or cyberspace. Using 3D computer graphics, multisensory interactive interface devices and high resolution displays, a virtual world can be realized in which one can pick up imaginary objects as if they are real. Using this technology, the virtual space decision support system (VSDSS) lets users design virtual products and experience them while in virtual space. The VSDSS and its application to the unified sales/production system (US/PS) are described in this paper. At present, most computer-aided manufacturing systems are geared towards production in small lots and are unable to handle custom-designed products. Using the VSDSS, individuals will be able to design their own products. The VSDSS system should be designed so that the dreams of the individuals can be realized.
