Triggered by several head-mounted display (HMD) devices that have come to the market recently, such as Oculus Rift, HTC Vive, and Samsung Gear VR, significant interest has developed in virtual reality (VR) systems, experiences and applications. However, the current HMD devices are still very heavy and large, negatively affecting user experience. Moreover, current VR approaches perform rendering...

The aim of this study was to investigate the effects on gait induced by a completely immersive Virtual Reality (VR) with and without perturbation. Ten healthy subjects were analyzed during over-ground walking in different conditions: standard gait, VR gait and perturbed VR gait. Results showed that subjects immersed in the virtual environment walked slowly, with decreased cadence (-13%) and str...

This paper explores the development of virtual reality (VR) use in education and the emergence of mobile VR based content creation and sharing as a platform for enabling learner-generated content and learner-generated contexts. The author argues that an ecology of resources that maps the user content creation and sharing affordances of mobile devices, social media, mobile head mounted displays ...

Literature on virtual reality (VR) and psychology has focused on the influence that some basic psychological processes have on VR. Although psychological processes may be defined as common to all humans, there are individual differences that might make it difficult to provide the same VR experience for everyone. Of the several personality and psychological variables that might be relevant to th...

In this paper we present a dual-purpose interaction metaphor for desktop-based and virtual reality (VR) interaction in VR system environments. Many VR interaction techniques enable users to perform 6 degrees of freedom (DOF) manipulation tasks. However, designers of most GUIs have only standard desktop devices in mind for using them. Therefore porting desktop applications to VR systems often fa...

INTRODUCTION The essential feature of post-traumatic stress disorder (PTSD) is the development of characteristic symptoms following exposure to one or more traumatic events. According to evidence-based intervention guidelines and empirical evidence, one of the most extensively researched and validated treatments for PTSD is prolonged exposure to traumatic events; however, exposure therapy can p...

In this document we describe the scheme used for labelling the open-source Ukwabelana Zulu corpus as well as the rules employed for the Part-of-speech (POS) tagger used to assign POS to morphologically analysed words. A detailed description of the Zulu morphology, the corpus itself and its generation is given in [2]. All resources can be downloaded from http://www.cs.bris.ac.uk/Research/Machine...

BACKGROUND This is the first controlled study to explore whether adjunctive immersive virtual reality (VR) can reduce excessive pain of soldiers with combat-related burn injuries during wound debridement. METHODS Patients were US soldiers burned in combat attacks involving explosive devices in Iraq or Afghanistan. During the same wound care session using a within-subject experimental design, ...

In this paper, the problem of resource management is studied for a network of wireless virtual reality (VR) users communicating using an unmanned aerial vehicle (UAV)-enabled LTE-U network. In the studied model, the UAVs act as VR control centers that collect tracking information from the VR users over the wireless uplink and, then, send the constructed VR images to the VR users over an LTE-U d...

We build on the increasing availability of Virtual Reality (VR) devices and Web technologies to conduct behavioral experiments in VR using crowdsourcing techniques. A new recruiting and validation method allows us to create a panel of eligible experiment participants recruited from Amazon Mechanical Turk. Using this panel, we ran three different crowdsourced VR experiments, each reproducing one...
