Conception et évaluation d'un système transparent de capture de mouvements des mains pour l'interaction 3D temps réel en environnements virtuels

Abstract : The purpose of this thesis is to propose and evaluate a markerless system for capturing hand movements in real time to allow 3D interactions in virtual environment (VE). Tools such as keyboard and mouse are not enough for interacting in 3D VE; current motion capture systems are expensive and require wearing equipments. Systems based on cameras and image processing partially fill these gaps, but do not yet allow an accurate, efficient and real-time 3D motion capture. Our system provides a solution to this problem with a 3D camera. We have implemented modalities that allow a more natural interaction with objects and VE. The goal of our system is to obtain performances at least equal to those of common tools in virtual reality while providing a better overall acceptability (i.e., usefulness, usability, immersion). To achieve this goal, we conducted three experimental studies involving over 100 participants. With the first study, we compared the first version of our system (based on a 3D Camera MESA SwissRanger) to a traditional mouse, for a selection task. The second experiment was focused on the study of the realization of objects-manipulation tasks (position, orientation, scaling) and navigation tasks in VE. For this study, we compared the improved version of our system (based on Microsoft Kinect) with data gloves associated with magnetic sensors. An additional study concerns the evaluation of new modalities of interaction, implemented based on participants' feedback of the second study.
