In this paper, a method is described that improves the perceived “smoothness” of motion depicted on rasterised Virtual Reality displays, by utilising the powerful information already contained in the virtual-world engine. Practical implementation of this method requires a slight realignment of one’s view of the nature of a rasterised display, together with modest modifications to current image ...

In this paper, we work toward creating display systems that can present virtual proofs and replicas that behave like real physical surfaces in the actual lighting environment surrounding the display. The goal is to recreate the experience of directly viewing a reflective surface while using self-luminous display screens. We use a computational approach that models the physical light sources and...

In the field of virtual reality and teleoperation, haptic interaction between human operator and a computer or telerobot plays an increasingly important role in performing delicate tasks, such as robotic telesurgery, virtual reality based training systems for surgery, virtual reality based rehabilitation systems (Dario et al, 2003) (Taylor, Stoianovici, 2003) (Popescu, et al, 2000), etc. These ...

Three alternatives to the traditional head mounted Virtual Reality display are described. One configuration is the Virtual Holographic Workstation; an external stereo CRT viewed by a user wearing head tracking stereo shutter glasses. Another is a Computer Augmented Reality camcorder, where virtual objects are composited onto live video using six axis tracking information about the location of t...

Virtual surface characteristics of tactile displays are investigated to characterize the feeling of human touch for a haptic interface application. In order to represent the tactile feeling, a prototype tactile display incorporating Magneto-Rheological (MR) fluid has been developed. Tactile display devices simulate the finger's skin to feel the sensations of contact such as compliance, friction...

Understanding an unfamiliar environment can be a difficult and time-consuming task, yet one at which users can be particularly effective when it is accomplished collaboratively. We are investigating techniques that support communication among multiple users within a group to help them explore their surroundings together. Our focus is on determining how each user’s interface is designed, based o...

abstract background: in recent studies, using virtual reality (vr) has been proposed as a nonpharmacological method for anxiety reduction, but until this time, its effects have not been assessed on anxiety during episiotomy repair. this study aimed to determine the effect of audiovisual distraction (vr) on anxiety in primiparous women during episiotomy repair. materials and methods: this clinic...
