Collaborative Virtual Environments (CVEs) actively support human collaboration within a computer based virtual space. CVEs employing distributed virtual reality technologies have the potential to support very large numbers of simultaneous participants. However the creation of such systems remains problematic. Particular issues include the realisation of sociologically appropriate affordances fo...

with the rise in the use of afm (atomic force microscope), we have witnessed a growing use of atomic microscope based nanorobots in the precise displacement of various particles. there are certain limitations to the application of nanorobots in the moving of nanoparticles. one of the most important of these limitations is the lack of an appropriate image feedback concurrent with the displaci...

Virtual reality is a new technology that simulates a three-dimensional virtual world on a computer and enables the generation of visual, audio, and haptic feedback for the full immersion of users. Users can interact with and observe objects in three-dimensional visual space without limitation. At present, virtual reality training has been widely used in rehabilitation therapy for balance dysfun...

Social Anxiety affects a significant number of people, limiting their personal and social life. We describe an interactive Virtual Reality approach to the exposure therapy for social anxiety, resorting to virtual characters that exhibit combinations of facial and body expressions controllable in real-time by the therapist. The application described in this paper updates and significantly improv...

More than two thirds of the individuals who have strokes are over the age of 65. Therefore, as the global population continues to age, the risk of stroke is expected to increase substantially. Virtual reality (VR) is an emerging therapy that holds promise for the rehabilitation of patients with chronic stroke conditions. VR is an interactive, computer-based simulation of real life tasks, occurr...

This paper describes virtual reality and some of its potential applications in rehabilitation and therapy. Some aspects of this technology are discussed with respect to different problem areas (sensorimotor impairments, autism, learning difficulties), as well as previous research which investigated changes within some motor and motivation parameters in relation to rehabilitation of children wit...

School phobia is characterized by fear to diverse events associated to school such as being beaten by a classmate, bullied or criticised in front of the class, having to speak in public, doing exams, getting undressed to practice sports, etc. and can frequently cause young children to a chronic school refusal leading to significant social and academic difficulties. In older children and adolesc...

Recently, many human-scale virtual environments (VEs) have been developed and studied for achieving realistic virtual reality. Immersive projection displays, like the CAVE system, become widespread, and most researchers already know the great effect of reality and immersion with the human-scale VEs. However, five senses other than vision are not so emphasized in human-scale VEs. In order to enh...
