AbstractThe selection and manipulation of objects in Virtual Reality face application developers with a substantial challenge as they need to ensure a seamless interaction in three-dimensional space. Assessing the advantages and disadvantages of selection and manipulation techniques in specific scenarios and regarding usability and user experience is a mandatory task to find suitable forms of interaction. In this article, we take a look at the most common issues arising in the interaction with objects in VR. We present a taxonomy allowing the classification of techniques regarding multiple dimensions. The issues are then associated with these dimensions. Furthermore, we analyze the results of a study comparing multiple selection techniques and present a tool allowing developers of VR applications to search for appropriate selection and manipulation techniques and to get scenario dependent suggestions based on the data of the executed study.

Abstract This paper discusses the development of a virtual reality (VR) interface for the visualization of Computational Fluid Dynamics (CFD) data. The application, VR-CFD, provides an immersive and interactive graphical environment in which users can examine the analysis results from a CFD analysis of a flow field in three-dimensional space. It has been tested and implemented with virtual reality devices such as the C2, head mounted display (HMD) and desktop VR. The application is designed to read PLOT3D structured grid data and to display the flow field parameters using features such as streamlines, cutting planes, iso-surfaces, rakes, vector fields and scalar fields. Visualization Toolkit (VTK), a data visualization library, is used along with OpenGL arid the C2 VR interface libraries, to develop the application. Analysts and designers have used VR-CFD to visualize and understand complex three-dimensional fluid flow phenomena. The combination of three-dimensional interaction capability and the C2 virtual reality environment has been shown to facilitate collaborative discussions between analysts and engineers concerning the appropriateness of the CFD model and the characteristics of the fluid flow.

The authors built a pseudo-immersive three-dimensional computer generated virtual environment (VE) as a shell for research in detailed collision detection. The purpose of the virtual world construction described in this paper is to handle engineering applications such as the mechanical assembly and disassembly of complex systems. A virtual space ball is attached to the VE in order to control the motion of virtual objects in that environment. This software interface simulates a real three-dimensional space ball device. The contribution of the pseudo-immersive system removes the absolute necessity for expensive Virtual Reality equipment and software for research work on virtual reality.

Three Dimensional Space

Virtual Reality is implemented by a combination of technologies that are used in order to visualize and provide interaction with a virtual environment. These environments often depict three-dimensional space which may be realistic or imaginary, macroscopic or microscopic and based on realistic physical laws of dynamics, or on imaginary dynamics. The multitude of scenarios that VR may be used to depict make it broadly applicable to the many areas in education. A key feature of VR is that it allows multi-sensory interaction with the space being visualized. Here we look at how this combination of multi-sensory visualization and interactivity make VR ideally suited for effective learning and try to explain this effectiveness in terms of the advantages afforded by active learning through experiences. We also consider some of the applications of VR in education and also some of its drawbacks.

Decision Mechanisms

Immersive virtual reality is a promising technology for planning participation. The paper contributes to the literature by comparing the latest virtual reality technology using head-mounted display with conventional graphic representation (pictures of rendered three-dimensional environments in this case) in terms of the effects on the participants’ preferences for the plans and their underlying decision mechanisms. Using a stated choice experiment based on a real-world project of street renewal, we collected choice data from 48 university students from non-design majors. We found significant quantitative but limited qualitative differences between the aggregate preferences under virtual reality and conventional graphic representation, and some generally unappealing features under conventional graphic representation were more favored under virtual reality. Results of the discrete choice modeling showed the individual decision mechanisms became more homogeneous under virtual reality. Virtual reality had stronger impacts on the female participants than the male participants. The females had more aggregate preference reversals, larger preference differences, and stronger changes in the decision mechanism. But the mechanisms of the two genders converged under virtual reality. The findings can be used to design better participatory processes with virtual reality and conventional graphic representation properly applied according to their capabilities.
