Evaluation of Pseudo-Haptic Feedback for Simulating Torque: A Comparison between Isometric and Elastic Input Devices
Found in: World Haptics Conference
By Anatole Lécuyer, Jean-Marie Burkhardt, Jildaz Le Biller, Marco Congedo
Issue Date:March 2005
pp. 316-322
The objective of this paper is twofold. First, it aims at positioning the performance of under-actuated haptic devices as compared to fully-actuated haptic devices and unactuated devices (i.e. input devices) in virtual reality. Second, it proposes a techni...
 
Evaluation of Pseudo-Haptic Feedback for Simulating Torque: A Comparison between Isometric and Elastic Input Devices
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Alexis Paljic, Jean-Marie Burkhardt, Sabine Coquillart
Issue Date:March 2004
pp. 216-223
In this work, we investigate whether pseudo-haptic feedback is suitable for simulating torque feedback. Pseudo-haptic feedback is based on the coupling of visual feedback and the internal resistance of an input device which passively reacts to the user's a...
 
Evaluation of the Command and Control Cube
Found in: Virtual Reality Conference, IEEE
By Anatole Lécuyer, Jean-Marie Burkhardt, Sabine Coquillart, Philippe Coiffet
Issue Date:March 2001
pp. 115
This paper describes a psychophysical experiment designed to study the phenomenon of illusion which occurs with the pseudo-haptic feedback (see [13]), and to identify the moment when this illusion occurs: the
