Computing power is an integrated part of our physical environment, and since our physical environment is three-dimensional, the virtual studio technology, with its unique potential for visualizing digital 3D objects and environments along with physical objects, offers an obvious path to pursue in order to envision future usage scenarios in the domain of pervasive computing.We label the work method virtual video prototyping, which grew out of a number of information systems design techniques along with approaches to visualization in the field of architecture and set design.We present a collection of virtual video prototyping cases and use them as the platform for a discussion, which pinpoint advantages and disadvantages of working with virtual video prototyping as a tool for communication, experimentation and reflection in the design process. Based on more than ten cases we have made the observations that virtual video prototypes 1) are a powerful medium of communication in development teams and for communication with industry partners and potential investors, 2) support both testing and generating ideas 3) are particular suited for addressing spatial issues and new ways of interacting. In addition practical use of virtual video prototypes has indicated the need to take into account some critical issues including a) production resources, b) hand-on experience, and c) the seductive power of virtual video prototypes.

A VR-based system for the virtual prototyping of shoes employs a user interface that mimics shoe designer's conventional work style, using a pen and a shoe last as 3D proxy objects. Users sketch design lines onto the last. For this task, the system employs an algorithm for real-time sketch recognition on curved surfaces. On the basis of the framework of curves, the system creates further design elements (for example, leather pieces) to complete the model. Users can employ three pen-based interaction metaphors to interact directly with design elements, to input values, or to make choices from a menu. A user study shows that conventional designers can easily learn and apply these interaction methods. [ABSTRACT FROM PUBLISHER]

The article describes a system that grew out of the U.S. NASA research project at the Jet Propulsion Laboratory. Its goal is to study the application of computer graphics to the problem of rapidly and interactively exploring and analyzing very large amounts of scientific data gathered during the execution, computations, or computer simulations. Objectives of the research program are to develop a software environment and test bed to support the rapid prototyping of visual data analysis applications, while maintaining the high level of performance necessary for interactive manipulation of graphical displays to develop a user interface that is truly intuitive, allowing quick access to the software for the novice as well as the advanced user, to provide a suite of sample applications that are useful across a variety of scientific disciplines and to provide tools to support user development of applications for this environment. The Linked Windows Interactive Data System, or LinkWinds, is both a test bed for concepts resulting from this research and a prototype product of the effort.

Focuses on the developments in the rapid prototyping industry in the United States. Transformation of rapid prototyping technology to rapid manufacturing; Limitations to the applicability of rapid manufacturing processes; Advantages of rapid prototyping applications.
The article focuses on Front's Sketch Furniture Project, in which designers trace invisible lines in their air, creating blueprints that are captured by motion sensory equipment and made into inanimate objects in liquid plastic by rapid prototyping technology. The sensory equipment recognizes motions of a specialized pen and translates them to three-dimensional graphics files used in computer programs. A laser beam is used to cast liquid plastic layer by layer.
