Ultimately, the user finishes with an implemented system. Each of these steps are described in detail, as well as some of the tools which support them. These initial prototypes can be used to efficiently check design alternatives, to validate the functionality and to find time and cost critical parts of the system. To meet these requirements an initial software specification with Java is proposed in this paper. It will be shown that the inherent features of the Java language combined with the proposed extensions provide a powerful design environment for building and analysing an initial prototype.
Experimental results underline the efficiency of the presented approach.
Virtual reality prototyping is a promising technology that combines the virtual reality approach to advanced modeling, simulation and user interface techniques. The technology adjoins development models of different engineering disciplines to an executable simulation model of a product. A designer, or a customer, can see, touch, hear and operate a future product before its physical implementation with lower cost and effort than earlier. In this paper, the virtual reality prototyping research in the field of consumer electronics and telecommunications is described. The possibilities and benefits of the technology are presented, and a process and research environment for the development of virtual prototypes is introduced.
