Geometric (proxy-based) haptic rendering algorithms are widely used in impedance-type haptic rendering. Such methods are useful for developing complex virtual environment because ...
Virtual agents, to be expressive, not only need algorithms for displaying the subtleties of human behaviour, but also require environments and tools so that people can author them....
Tactile displays that enhance appreciation of virtual and real environments are becoming increasingly common. Extending a series of prior studies, we explored spatial resolution f...
To make optimal use of distributed virtual environments (DVEs), we must understand and quantify the effects that latency has on user performance. Although the effects of visual la...
In this paper we describe the development of an interactive virtual reality (VR) system that aims to realistically simulate specific paracentesis clinical procedures (particularly ...
