PURPOSE It is estimated that 50% to 75% of individuals who experience a stroke have persistent impairment of the affected upper limb (UL). There is a need to identify the best training strategies for retraining motor function of the UL. One intervention showing promise is virtual reality (VR), using either immersive or nonimmersive technology. Before recommending VR for use in clinical practice...
Our understanding of Virtual Reality (VR) as a communications medium is not as well developed as the technologies of VR themselves. This paper presents the practical application of a content model of VR, which aims to alleviate this problem. First of all a characterisation of the aesthetics of VR is put forward against which the practicalities of the content model can be judged. Then, the conte...
The feasibility and efficacy of virtual reality job interview training (VR-JIT) was assessed in a single-blinded randomized controlled trial. Adults with autism spectrum disorder were randomized to VR-JIT (n = 16) or treatment-as-usual (TAU) (n = 10) groups. VR-JIT consisted of simulated job interviews with a virtual character and didactic training. Participants attended 90 % of laboratory-base...
It is difficult to design the Virtual Reality (VR) Environment which controls VR sickness and promotes presence. This is because the relationship between the user's susceptibility to VR sickness and a sense of presence, determined by velocity and visual angle of the visual information, involves a trade-off between the two. Then we propose the optimal value search system which computes efficient...
The present study investigates whether a virtual reality (VR) intervention can influence pain catastrophizing, pain self-efficacy and other pain-related measures reported during a cold-pressor experience. Forty-five healthy participants underwent two consecutive cold-pressor trials, one using VR and one without VR exposure, in counterbalanced order. The VR intervention encouraged participants t...
The number of different virtual reality (VR) systems and corresponding interaction techniques is quite manifold, today. For dedicated input devices, data types and application domains specific interaction techniques have been developed. Thereby a wide audience of researchers can benefit from using VR systems. A drawback is, that for non-VR specialists it is nearly impossible to get a clear over...
Drug craving has purportedly been linked to relapse and to substance use. For over two decades, cue reactivity has been a viable method to assess craving and physiological reactions to drug stimuli. However, traditional cue reactivity has faced the following limitations: austere situations or stimuli, lack of complex cues, lack of standardization, and limited generalization outside of the lab s...
BACKGROUND Virtual reality (VR) distraction is a nonpharmacological method to prevent acute pain that has not yet been thoroughly explored for anesthesiology. We present our experience using VR distraction to decrease routine intravenous sedation for patients undergoing preoperative perineural catheter insertion. METHODS This 1-month quality improvement project involved all elective unilatera...
Although much is known about vancomycin-resistant (VR) Enterococcus faecium, little is known about the epidemiology of VR Enterococcus faecalis. The predilection of VR E. faecalis to transfer the vancomycin resistance determinant to Staphylococcus aureus is much greater than that of VR E. faecium. The epidemiology of VR E. faecalis has important implications regarding the emergence of vancomyci...
This paper describes VR Juggler, an Open Source platform used to develop and run virtual reality applications. We emphasize VR Juggler’s ability to provide a uniform VR application environment and to allow extendibility to new devices without affecting existing applications. These features enable VR applications to evolve along side other technologies with minimal or no new developmental efforts.
