— To what extent do people behave in immersive virtual environments as they would in similar situations in a physical environment? There are many ways to address this question, r...
The growth in interest in virtual environments in CSCW has focused on co-operation within these environments. Little consideration has been given to how users manage these environ...
Abstract. A novel interactive virtual needle insertion simulation is presented. The insertion model simulates three-degree-of-freedom needle motion, physically-based needle forces,...
—This paper presents a framework for preserving privacy in video surveillance. Raw video is decomposed into a background and one or more object-video streams. Objectvideo streams...
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....
