BACKGROUND Novel virtual reality rehabilitation systems provide the potential to increase intensity and offer challenging and motivating tasks. The efficacy of virtual reality systems to improve arm motor function early after stroke has not been demonstrated yet in sufficiently powered studies. The objective of the study is to investigate whether VR training as an adjunct to conventional therap...

Virtual reality is a media allowing users to interact in real time with computerized virtual environments. The application of this immersive technology to cognitive behavioral therapies is increasingly exploited for the treatment of mental disorders. The present study is a review of literature spanning from 1992 to 2012. It depicts the utility of this new tool for assessment and therapy through...

This paper presents our novel concept Outdoor Virtual Reality. By using outdoor augmented reality techniques we propose to build very wide area virtual reality systems, outdoor virtual reality. The concept of outdoor virtual reality is compared and contrasted to traditional definitions of augmented reality and virtual reality. We present our flexible Tinmith-evo5 software architecture as a plat...

OBJECTIVE To establish the stability and validity of information collected in a virtual reality environment from persons with traumatic brain injury (TBI). DESIGN Prospective correlation design to examine 3-week test-retest results for equivalence reliability between computer-simulated and natural environments. SETTING A residential rehabilitation center for brain injury. PARTICIPANTS Fif...

Technology is developing quickly, making a lot of things that were before impossible feasible. Virtual reality (VR) and augmented (AR) are two examples the cutting-edge technology that, only few years ago, considered science fiction. However, they now an essential component everyday life. The distinction between & virtual one causes most misunderstanding in world. While Reality entirely imm...

In this paper a model for usability/accessibility evaluation methods for appliance in Web 3D social software is being introduced and exemplified by looking at the currently popular phenomenon Second Life. The social aspect of specific Web 3D functions/applications will be in focus, as well as the issue of accessibility which poses an important aspect in Virtual Reality (VR) worlds. This plays a...

This work describes the design and implementation of the Virtual Reality Tool (VRT), a core component within the educational platform developed for the European research project IST-2001-33184, SLIM-VRT (Self Learning Integrated Methodology – Virtual Reality Tool). The main objective of this project is to propose an alternative for integrated maritime self-learning on board and ashore based on ...

Microscopic pedestrian simulation models are based on local interactions between agents. Many interactions occur between walkers, with many factors of influence. There is a need for observations of individuals facing interactions in crowds to better understand them and improve the level of realism of simulation algorithms. We explore Virtual Reality (VR) as an experimental tool to perform such ...
