Virtual Prototyping VP tools enable us to investigate, explore, and communicate the performance and behavior of an evolving product and thus reduce the number of physical prototypes needed. Finite Element FE and MultiBody Simulation MBS tools are frequently used for virtual prototyping in mechanical engineering today. These tools can effectively...
This paper presents a method of warehouse simulation model implementation using concepts of Virtual Reality VR. The basic idea is to compare the "Real process" controlled by operator with his/her heuristics to the "Virtual process" represented by a simulation model, controlled by the optimization algorithm. The optimization algorithm is based...
The management of burn injuries is reported as painful, distressing and a cause of anxiety in children and their parents. This study investigates whether playing a Virtual Reality VR game, decreases procedural pain in children aged 5-18 years with acute burn injuries. The paper reports on the findings of a...
This paper demonstrates the utilization of immersive virtual reality environments in the investigation of operations simulation results. The paper outlines the benefits offered by virtual reality over the traditional two-dimensional computer interfaces, such as the monitor, keyboard and mouse. The paper describes the state of the art in the area...
This paper discusses a two-step virtual reality based conceptual design tool that enables industrial designers to create sketches of their ideas in 3-dimensional space in real time. In the developed sketching tool, the rough shapes of products are generated by tracing the trajectory of the data-gloves worn by the designer....
The U.S. furniture, home furnishings, and textile industries are faced with threats from less expensive imports and as a result must become more strategic with regard to consumer preferences, effective marketing, and supply chain management. As a significant market for textiles, the sustainability of furniture and home furnishing industries is...
A study examined the use of virtual reality imagery in conjunction with MADYMO MAthematical DYnamical MOdels computational modeling to facilitate prototype development and existing-design optimization of crashworthy Child Restraint Systems CRS. The purpose of this paper is twofold. The first describes the efforts to predict strains induced on the surface...
With advancements in software applications and computer display technology, it is now possible to place construction students within a large-scale, immersive projection display that allows them to experience and experiment with a 3D, full-scale virtual model of a construction project. This advanced visual communication can significantly improve the ability of...
A visual interface has been developed to provide a means for users to visualize the steel structure represented by a CIMsteel Integration Standards Release 2 (CIS/2) file. A CIS/2 file provides for the electronic exchange of data directly between various steel CAD software applications. Using a web-accessible translator, objects in...
This paper reports on a study of industrial applications of virtual reality in construction. A multiple case study approach is taken and eleven organizations that are lead users of the technology are studied. Their strategies and business drivers for the use of virtual reality are identified and emerging patterns of...
Construction projects can gain major benefits from application of virtual environments. The virtual reality techniques help designers to communicate with each other, as well as with the decision makers and with the end-users. In the future, the whole product model of a new building should form one virtual building, which...
This paper presents ongoing research to improve construction education through the use of virtual reality and 4D CAD Computer Aided Design modeling (3D design plus time) of construction processes and projects. The authors have implemented 4D CAD modeling into the undergraduate Architectural Engineering program. The authors are also experimenting with...
The scheduling of activities is of vital importance for the delivery of a successful construction project. Traditionally experienced construction planners, with in-depth knowledge of potential conflict between various construction tasks, generate the project plan. This information is then communicated to other members of the project team by means of a...
The STL or Stereo lithography format, established by 3D systems, gathers the geometric data of the model in a number of triangular surfaces. It can be in ASCII or binary format, and is a de facto standard in the Rapid Prototyping RP world. RP has developed greatly over the last...
Virtual Reality VR has now emerged as a promising tool in many domains of therapy and rehabilitation. What makes VR application development in the therapy and rehabilitation sciences so distinctively important is that it represents more than a simple linear extension of existing computer technology for human use. VR offers...
To public relations professionals, the Web is both a powerful tool of communication as well as a dangerous threat to organizational well being. Properly used, the Web represents the ultimate communication tool for building relationships between and organization and its publics, both internal and external. The Web can deliver messages...
Studierstube is an operating system for applications in virtual reality. It supports multiple users collaborating in a distributed system. While initially developed for scientific visualization, the generic approach supports almost any kind of VR application on a wide range of VR-hardware. Inherent concepts of Studierstube - like real-time graphics, high-level...
This white paper describes an experimental performance-driven animation system for an avatar face using model-based video coding and audio-track driven lip animation. Model-based video coding, also known as knowledge-based video coding, has emerged as a very low bit rate video compression method suitable for videoconferencing and interactive virtual reality applications....
Synchronous collaboration in virtual reality spaces has specific requirements that differ from those of other application data, leading to a different communication approach. Update messages corresponding to the change in the state of a shared object must be communicated both reliably and in a timely manner among users. While a...
The white paper deals with the High interactivity in real-time environments that requires new system design concepts for virtual reality environments. The paper defines the understanding of a modern system and describes the prototypical system lightning, which addresses some of the new features and thus these techniques serves the main...
