In the past few years, there have been some significant advances in consumer virtual reality (VR) devices. Devices such as the Oculus Rift, HTC Vive, Leap Motion™ Controller, and Microsoft Kinect® are bringing immersive VR experiences into the homes of consumers with much lower cost and space requirements than previous generations of VR hardware. These new devices are also lowering the barrier to entry for VR engineering applications. Past research has suggested that there are significant opportunities for using VR during design tasks to improve results and reduce development time. This work reviews the latest generation of VR hardware and reviews research studying VR in the design process. Additionally, this work extracts the major themes from the reviews and discusses how the latest technology and research may affect the engineering design process. We conclude that these new devices have the potential to significantly improve portions of the design process.
Leveraging virtual reality (VR) technology to enhance engineering design reviews has been an area of significant interest for researchers since the advent of modern VR. The ability to interact meaningfully with 3D engineering models in these VR design reviews is an important, though often neglected, capability due to the difficulty of performing data translation between native CAD data and VR compatible file formats. An automated synchronization interface was developed between a VR design review environment and a commercial CAD package that stream-lines the data translation process and enables enhanced visualization and manipulation tools. User experiments were performed to explore the hypothesis that allowing users to perform CAD-like view transformations and geometric manipulations in VR design reviews improves design understanding and decision making. Analysis of the experiment results show that enhanced interaction tools provide statistically significant advantages over a baseline VR design review environment for complex 3D models.
Since the advent of modern computer-aided design software, engineers have been divorced from the highly collaborative environment previously enjoyed. Today's highly complex designs require modern software tools and the realities of a global economy often constrain engineers to remote collaboration. These conditions make it highly impractical to collaborate locally around physical models. Various approaches to creating new collaboration tools and software, which alleviate these issues, have been tried previously. However, past solutions either used expensive hardware, which is not widely available, or used standard two-dimensional (2D) monitors to share three-dimensional (3D) information. Recently, new low-cost virtual reality (VR) hardware has been introduced, which creates a highly immersive 3D experience at a tiny fraction of the cost of previous hardware. This work demonstrates an immersive collaborative environment built using a network of this hardware, which allows users to interact with gestures virtually and conducts a study to show its advantages over traditional video conferencing software.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
