Virtual reality (VR) is a powerful multimedia visualization technique offering a range of mechanisms by which many new experiences can be made available. This paper deals with the basic nature of VR, the technologies needed to create it, and its potential, especially for helping disabled people. It also offers an overview of some examples of existing VR systems.

Simulation and visualization of rover behavior are critical capabilities for scientists and rover operators to construct, test, and validate plans for commanding a remote rover. The VIPER system links these capabilities, using a high-fidelity virtual-reality (VR) environment, a kinematically accurate simulator, and a flexible plan executive to allow users to simulate and visualize possible exec...

There is now a substantial literature investigating virtual reality exposure therapy (VRET) as a viable treatment option for anxiety disorders. In this meta-analysis we provide effect size estimates for virtual reality treatment in comparison to in vivo exposure and control conditions (waitlist, attention control, etc.). A comprehensive search of the literature identified 13 studies (n=397) tha...

One possible alternative to standard in vivo exposure may be virtual reality exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment. Virtual reality exposure (VRE) is potentially an efficient and cost-effective treatment of anxiety disorders. VR...

Some clinicians have suggested using virtual reality environments to deliver psychological interventions to treat anxiety disorders. However, given a significant body of work on cybersickness symptoms which may arise in virtual environments - especially those involving simulated motion - we tested (a) whether being exposed to a virtual reality environment alone causes anxiety to increase, and (...

BACKGROUND Persecutory delusions may be unfounded threat beliefs maintained by safety-seeking behaviours that prevent disconfirmatory evidence being successfully processed. Use of virtual reality could facilitate new learning. AIMS To test the hypothesis that enabling patients to test the threat predictions of persecutory delusions in virtual reality social environments with the dropping of s...

Virtual reality exposure therapy (VRET) is one of the few interventions supported by randomized controlled trials for the treatment of combat-related posttraumatic stress disorder (PTSD) in active duty service members. A comparative effectiveness study was conducted to determine if virtual reality technology itself improved outcomes, or if similar results could be achieved with a control exposu...

Matthew Price, Page Anderson, Georgia State University, and Barbara O. Rothbaum, Emory University School of Medicine Virtual reality exposure has recently emerged as an important tool for exposure therapy in the treatment of fear of flying. There have been numerous empirical studies that have evaluated the effectiveness of virtual reality exposure as compared to other treatments including in vi...

normal 0 false false false en-us x-none ar-sa background: despite the potential benefits of virtual reality technology in physical rehabilitation, only a few studies have evaluated the efficacy of this type of treatment in patients with neck pain. objective: the aim of this study was to compare the effects of virtual reality training (vrt) versus conventional proprioceptive training (cpt) in pa...

Introduction Virtual reality exposure therapy (VRET) is a treatment in virtual environment based on the representation of patient’s disease reality. VRET means getting used to specific situation by intentionally facing fearful ‘exposure technique.’ By repeatedly exposing patient situation, end, inducing intensity fear decrease without avoiding situation. was initially treat phobias, anxiety dis...
