Tutorial 3 - Integration of Haptics in Virtual Environments, March
10th
http://conferences.computer.org/vr/2007/program/tutorials.html

"My presentation deals with a recent and novel concept in the field of
haptic interaction with virtual environments: Pseudo-Haptic Feedback.

With PH, it is possible to use a passive device such as a classical
computer mouse or a spaceball to simulate force-feedback.

Outline
Introduction
Simulation of pseudo-haptic properties
Friction, stiffness, weight, textures
Pseudo-haptic applications
Training, entertainment, GUI, medical
Lessons learned
Conclusion

I will describe how Pseudo-Haptic feedback (PH) has been already used
to simulate different « classical » haptic properties, such as :
friction,
stiffness, weight, or textures.
Then I will describe how it has been transferred into several
applications,
such as for training in Virtual Reality, entertainment, graphical
user
interfaces (GUI), etc"
