Retour sensoriel du toucher dans les environnements virtuels

subject

description

This thesis tackles the subject of the feedbacks of interactions in virtual environments. The theoretical part addresses the different perception schemes and the corresponding haptic modalities. We especially focused on the relevance of each modality for each use-case, on the compatibility with the visual systems which take an important place in virtual reality, and on the problematics of each situation. These studies led us to evaluate passive haptics and sensory substitution for interactions in CAVEs. The results show the importance of choosing the right modality relative to the scenario design. We also evaluated how mismatched the visual and haptic workfield can be, and how the performance of interactions suffers from this fact. Ultimately, we tested a few software-based methods meant to improve the performance of the interactions of the subjects.
