Bio

Anatole Lécuyer is a research scientist at INRIA, the French National Institute for Research in Computer Science and Control (www.inria.fr) since 2002. His main research interests include: virtual reality, 3D interaction, haptic feedback, pseudo-haptic feedback and brain-computer interfaces. In 1996, he graduated in France from Ecole Centrale Lille, and received M.S. from University of Lille 1. He received his Ph.D. in Computer Science in 2001 from University of Paris XI, France. He spent one year as a research engineer in the French Commission for Atomic Energy, Fontenay-aux-Roses, France. At IRISA laboratory, Rennes, France, he is a member of the BUNRAKU research team (head: Dr. S. Donikian). He is the coordinator of the Open-ViBE National project on Brain-Computer Interfaces, and the former leader of the Working Group on Haptic Interaction of INTUITION European Network of Excellence. He is an associate editor of the ACM Transactions on Applied Perception, secretary of the French Association for Virtual Reality and secretary of the IEEE Technical Committee on Haptics.

Title:
Contribution to the Study of Haptic and Pseudo-Haptic Feedbacks and their Impact on Simulations of Assembly/Maintenance Operations in Aeronautics

Summary:
Sensory feedbacks provided by a system of Virtual Reality (VR) improve the interaction and the immersion of a user into the virtual world. In aeronautics, a sensory feedback on the haptic mode is perceived as being able to improve the conditions of simulation of assembly and maintenance operations in VR.

First we propose a new concept of haptic feedback : the pseudo-haptic feedback. This concept consists in exploiting the coupling between the visual feedback of the virtual scene and a passive haptic information generated by an action of the user. The pseudo-haptic feedback generates haptic illusions which are studied in detail.

Then two different prototypes are developed to provide for the need for haptic feedback in simulations of assembly and maintenance operations in aeronautics. A first prototype uses a force-feedback pen. It necessitates a haptic interaction technique aiming at transposing the missing torques as well as a haptic rendering of the collisions. A second prototype is developed in order to evaluate quantitatively the influence of the haptic information of collision in the course of the simulation of an assembly operation in VR. This benchmark uses a 2-screen workbench and a wearable haptic handle. Thanks to this prototype, it is thus possible to analyze the influence of the various sensory feedbacks of the environment on the results of the user.

Key words:
Virtual Reality, Haptic Feedback, Pseudo-Haptic Feedback, Haptic Perception, Haptic Illusion, Aeronautics Application, Workbench, Force Feedback.
