Bringing haptics and physical simulation together: haptic travel through physical worlds
This paper describes our efforts in bringing haptics closer to current dynamic virtual environments (VE). These interactive 3D worlds make more and more rise of physical simulations in order to increase realism. As a first step in closing the gap, we propose haptic travel that allows users to feel how their virtual representation navigates through the simulated world. In this Work, we show how we coupled stable haptic rendering to physical simulation in order to achieve this. By generating a force feedback field, based oil the user's input in combination with collision information provided by a rigid body simulator, we managed to provide the user with useful information Oil what is happening to its virtual representation. A humanoid animated character, which represents the riser, is coupled to tire rigid body object that represents the user in physical space. This character is animated according to the travel motions that the physical object makes, depending oil user input from the haptic device. Our approach is suitable for a whole set of applications and input devices and can reduce the number of devices necessary to interact in VEs. Copyright (c) 2006 John Wiley & Sons, Ltd.
