Virtual Reality (VR) is becoming an important tool in the engineering product development process. The virtual environment provides the user with the ability to interact with three-dimensional digital representations of products using natural head and hand motions. While interacting with digital objects in VR seems natural, the use of traditional two-dimensional menu systems does not always provide a convenient interface to controlling task specifications in the three-dimensional space. New human-computer-interfaces are needed for this emerging VR design tool. This paper will present the details of implementing a speaker-independent, command and control, speech recognition menuing system for a virtual reality application. The menuing system will be described as it is incorporated into a virtual environment for the design of spatial mechanisms. Design and technical issues involved in the interface creation process are discussed and the resulting interaction system is described.

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.

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.

Virtual reality (VR) has the potential to enable visualization of complex physical phenomena in their natural spatial scales and significantly improve the product development process. Virtual environments provide a tool for users to interact with three-dimensional models using intuitive methods in their natural spatial scales. This paper presents the implementation details of a virtual environment combining surround-screen virtual reality technology and particle tracing of massless particles to explore the benefits these tools bring to engineers seeking to understand the complex fluid behavior present in mixing processes. The implementation of interaction methods, including volume data selection using a convex hull approach, cutting plane generation, and the integration of a tablet PC as a user interface, will be presented. Design and technical details involved with the interaction methods will be discussed along with the resulting interactive virtual environment.

Abstract. In the context of this paper, a virtual reality application that allows each user to perform basic topographic processes on an already created 3D model inside a virtual environment was developed. Specifically, it is an application that allows the user to perform measurements of distances between two points in three-dimensional space and measurement and extraction of the three-dimensional coordinates of any point inside the virtual reality environment. Furthermore, the created application was evaluated in terms of its functionality, its usability and metric accuracy. Before the developing stage a research was done in order to determine which virtual reality system and which game engine is most suitable to use and finally the HTC Vive® virtual reality system and the Unreal Engine 4 game engine were used. Before all that, the concept of the virtual reality science was defined and also the virtual reality technologies in today's world were analyzed.

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 Despite advances in Computer-Aided Design (CAD) and the evolution of the graphical user interfaces, rapid creation, editing and visualization of three-dimensional (3D) shapes remains a tedious task. Though the availability of Virtual Reality (VR)-based systems allows enhanced three-dimensional interaction and visualization, the use of VR for ab initio shape design, as opposed to ‘importing’ models from existing CAD systems, is a relatively new area of research. Of interest are computer-human interaction issues and the design and geometric tools for shape modeling in a Virtual Environment (VE). The focus of this paper is on the latter i.e. in defining the geometric tools required for a VR-CAD system and in describing a framework that meets those requirements. This framework, the Virtual Design Software Framework (VDSF) consists of the interaction and design tools, and an underlying geometric engine that provides the representation and algorithms required by these tools. The geometric engine called the Virtual Modeler uses a graph-based representation (Shape-Graph) for modeling the shapes created by the user. The Shape-Graph facilitates interactive editing by localizing the effect of editing operations and in addition provides constraint-based design and editing mechanisms that are useful in a 3D interactive virtual environment. The paper concludes with a description of the prototype system, called the Virtual Design Studio (VDS), that is currently being implemented.1.

Abstract Virtual prototyping is a relatively new field which is significantly changing the product development process. In many applications, virtual prototyping relies on virtual reality tools for analysis of designs. This paper presents an architecture for a virtual prototyping system which was created for the analysis of automotive interiors. This flexible and open architecture allows the integration of various virtual reality software and hardware tools with conventional state-of-the-art CAD/CAM tools to provide an integrated virtual prototyping environment. This architecture supports the automatic transfer of data from and to parametric CAD systems, human modeling for ergonomic evaluations (first person and third person perspectives), design modifications in the virtual environment, distributed evaluations of virtual prototypes, reverse transfer of design modifications to the CAD system, and preservation of design intent and assembly intent during modifications in the virtual environment.

Virtual City

In recent years virtual environments (VEs) have become more and more popular and widespread due to the requirements of numerous application areas in particular in the 3D city visualization domain. Virtual reality (VR) systems, which make use of tracking technologies and stereoscopic projections of three-dimensional synthetic worlds, support better exploration of complex datasets. However, due to the limited interaction space usually provided by the range of the tracking sensors, users can explore only a portion of the virtual environment (VE). Redirected walking allows users to walk through large-scale immersive virtual environments (IVEs) such as virtual city models, while physically remaining in a reasonably small workspace by intentionally injecting scene motion into the IVE. With redirected walking users are guided on physical paths that may differ from the paths they perceive in the virtual world. The authors have conducted experiments in order to quantify how much humans can unknowingly be redirected. In this chapter they present the results of this study and the implications for virtual locomotion user interfaces that allow users to view arbitrary real world locations, before the users actually travel there in a natural environment.
