This paper discusses alternative approaches for interacting with virtual reality models on mobile devices, based upon work conducted as part of the locus project [6]. First, mobile virtual reality models are discussed within the established realityvirtuality continuum to demonstrate how this new mixed reality paradigm compares with augmented and virtual reality generally. Next, three prototypes...

INTRODUCTION Team training for procedural sedation for pediatric residents has traditionally consisted of didactic presentations and simulated scenarios using high-fidelity mannequins. We assessed the effectiveness of a virtual reality module in teaching preparation for and management of sedation for procedures. METHODS After developing a virtual reality environment in Second Life® (Linden La...

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...

Virtual Reality is a major asset and aspect of our future. It is the key to experiencing, feeling and touching the past, present and the future. It is the medium of creating our own world, our own customized reality. It could range from creating a video game to having a virtual stroll around the universe, from walking through our own dream house to experiencing a walk on an alien planet. With v...

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...

This paper proposes an overview of a study that conceptually unify the fields of virtual reality and teleoperation, by analyzing the notion of “assistance” to the operator of a virtual reality or tele-operation system. This analysis demonstrates that cases of assistance that are usually considered to belong to virtual reality are not conceptually different from what has been done in tele-operat...

Virtual reality is considered one of the fundamental directions, with computers and robotics, to reconfigure the global society in this century and even further, as one solution to overcome the current structural crisis, deep crisis with multiple consequences, most negative. This paper describes a possible involvement of virtual reality to shift from traditional engineering to virtual engineeri...

BACKGROUND Virtual reality provides a means of studying paranoid thinking in controlled laboratory conditions. However, this method has not been used with a clinical group. AIMS To establish the feasibility and safety of using virtual reality methodology in people with an at-risk mental state and to investigate the applicability of a cognitive model of paranoia to this group. METHOD Twenty-...

PC graphics technology, primarily driven by the video gaming industry, is becoming a possibility for the development of advanced virtual reality environments. The graphics and computational power required for virtual environments has been previously available exclusively on highend computing systems. Clustering multiple PCs to develop multi-processor multi-graphics systems capable of running an...

Virtual Reality (VR) or Virtual Environment (VE) is a type of human-computer interface that aims at creating the illusion of the user being immersed in a computer generated reality, providing a more direct communication link between users and the problem environment modelled by the computer system [Figuerido 1993]. Virtual Environments have been used to extend scientific visualisation. VE offer...
