Title:
Implementing Virtual Walls in Haptic Interfaces
Abstract:
When exploring a virtual environment with a haptic interface you are bound to bump into a virtual wall at some point. This basic element seems like a simple one to implement. It should simply resist the users attempts to penetrate it, providing the illusion of the presence of a stiff wall. However, with simple implementations, haptic interfaces become unstable at the surface of the wall, producing undesirable oscillations that make the wall feel like it is vibrating. This presentation will talk about the causes of these instabilities and some solutions offered by various authors.
