(IEEE Computer Society, 2003)We present a system for the automatic generation of bottom-up visual attention behaviours in virtual humans. Bottom-up attention refers to the way in which the environment solicits one?s attention without regard ... -
Collision handling for virtual environments
(2001)An efficient and realistic collision handling mechanism is fundamental to any physically plausible Virtual Environment. In this tutorial, we will first examine the applications of collision handling, and introduce the ... -
A framework for comparing task performance in real and virtual scenes
(ACM Press, 2005)In this paper, we describe a framework for comparing task performance in real and virtual environments. Realistic graphics, rear projection, haptics and rapid prototyping are used to match the virtual scene to the real ... -
Men behaving appropriately: integrating the role passing technique into the ALOHA system
(2002)The Adaptive Level of Detail for Human Animation (ALOHA) system is a platform for animating virtual humans within a virtual environment using levels-of-detail for geometry, motion and conversational behaviour. Until now ... -
