In spite of the large amount of “hype” that accompanied virtual reality (VR) earlier this decade, the field has produced only a few examples of demonstrably useful systems. Systems must be fielded and validated to show that VR is useful for purposes other than academic research. This paper discusses two VR systems developed at the Naval Research Laboratory that have received validation by stati...

This paper presents a model for an adaptive virtual reality (VR) service. The service adaptation, as described by the model, is performed by matching the parameters of – and possibly transcoding – the VR service in order to achieve the “best possible quality”, given the limitations of the terminal and access network, and taking into account individual user preferences. The matching process is b...

Using virtual reality (VR), we examined the barriers to and facilitators of functioning outdoors in persons with dementia (PwD) and investigated the generalizability of findings in VR to the real world. An existing town center was modeled in VR. PwD took part in both real-world and VR walks. Based on the results, the model was redesigned and then tested again. Performance on the walks improved,...

OBJECTIVE To report the use of virtual reality (VR) in pain intensity during dressing change of two burned children hospitalized in a Burn Treatment Center (BTC) in Southern Brazil. METHOD Case report on the use of VR during dressing change of two burned children hospitalized in a BTC, from May to July 2016. For assessing pain, a facial pain rating scale was applied at four times: just before...

Currently, the use of virtual reality (VR) is being widely applied in different fields, especially in computer science, engineering, and medicine. Concretely, the engineering applications based on VR cover approximately one half of the total number of VR resources (considering the research works published up to last year, 2016). In this paper, the capabilities of different computational softwar...

Objective: The utility of virtual reality (VR) pain management to reduce visceral or autonomic responses is presented in 115 cases during diagnostic upper gastrointestinal (GI) endoscopy. Methodology: 115 patients with peptic disease and gastro-oesophageal reflux were given an upper GI endoscopy with local anaesthesia. They were divided into two groups, 56 treated with VR and 59 without VR duri...

PURPOSE To systematically examine the effect of virtual reality (VR) on upper extremity (UE) function in children with cerebral palsy (CP) and assess the association among VR effects and children's characteristics and an intervention protocol. METHOD A systematic literature search was conducted in PubMed, CINAHL, Cochrane, and PsycINFO up to June 2013. Research studies involving children with...

Ventricular repolarization (VR) is a crucial step in cardiac electrical activity because it corresponds to a recovery period setting the stage for the next heart contraction. Small perturbations of the VR process can predispose an individual to lethal arrhythmias. In this review, I aim to provide an overview of the methods developed to analyse static and dynamic aspects of the VR process when r...
