BACKGROUND To date, a diagnosis in psychiatry is largely based on a clinical interview and questionnaires. The retrospective and subjective nature of these methods leads to recall and interviewer biases. Therefore, there is a clear need for more objective and standardized assessment methods to support the diagnostic process. The introduction of virtual reality (VR) creates the possibility to si...

Virtual reality (VR) is an emerging technology with a large potential to disrupt businesses. However, impacts of VR on companies have remained largely unexplored. We seek to fill this research gap with the business model concept as a well-structured foundation. Using the example of the media industry as one of the industries most affected by VR, our qualitative study classifies different types ...

The papers that follow stem from a symposium presented at the International Society for Posture and Gait Research (ISPGR) in Seville, Spain, in July 2015. Four speakers were charged with presenting their methods of applying virtual reality (VR) technology to obtain meaningful rehabilitation outcomes. The symposium aims to explore characteristics of VR that modify mechanisms supporting motor rel...

This paper explores the opportunities and challenges for Conceptual Modeling in the domain of Virtual Reality (VR). VR applications are becoming more feasible due to better and faster hardware, and due to new technology and faster network connections they also start to appear on the Internet. However, the development of such applications is still a specialized, time-consuming and expensive proc...

Brain-computer interface (BCI) and virtual reality (VR) are natural companions. BCI provides a new interaction technique for controlling VR, and VR provides a rich feedback environment for BCI while retaining a controlled and safe environment. The combination of VR and BCI allows for providing participants with novel experiences that are impossible otherwise. Both fields still pose many technol...

This study examined how desktop virtual reality (VR) enhances learning and not merely does desktop VR influence learning. Various relevant constructs and their measurement factors were identified to examine how desktop VR enhances learning and the fit of the hypothesized model was analyzed using structural equation modeling. The results supported the indirect effect of VR features to the learni...

Immersive, head-mounted virtual reality (HMD-VR) provides a unique opportunity to understand how changes in sensory environments affect motor learning. However, potential differences in mechanisms of motor learning and adaptation in HMD-VR versus a conventional training (CT) environment have not been extensively explored. Here, we investigated whether adaptation on a visuomotor rotation task in...

With today’s Virtual Reality (VR) systems, it is difficult to directly and precisely create and modify objects in a VR environment. This chapter presents an approach for solid modelling in a VR environment. Solid modelling in the VR environment is performed precisely in an intuitive manner through constraint-based manipulations. A hierarchically structured and constraint-based data model is dev...

OBJECTIVES Virtual reality (VR) simulation has the potential to standardize surgical training for robotic surgery. We sought to evaluate all commercially available VR robotic simulators. MATERIALS AND METHODS A MEDLINE(®) literature search was performed of all applicable keywords. Available VR simulators were evaluated with regard to face, content, and construct validation. Additionally, a su...

In this paper, we propose a simple variant of the original stochastic variance reduction gradient (SVRG) [1], where hereafter we refer to as the variance reduced stochastic gradient descent (VR-SGD). Different from the choices of the snapshot point and starting point in SVRG and its proximal variant, Prox-SVRG [2], the two vectors of each epoch in VRSGD are set to the average and last iterate o...
