Couplage visuo-haptique en environnement de conduite simulée

Abstract : Our visual-haptic system is requested as soon as our arms interact with our external environment. There is a coupling between visual and haptic modalities, so that the central nervous system takes in account the reliability and accuracy of both modalities in order to weigh their influence in the visual-haptic integration. Thus there is a rebalancing of the weight of each modality in the context of the visual-haptic solicitation. Typically, psychophysical studies implement short and repeated tasks, with or without sensory conflict, to understand the mechanisms underlying the visual-haptic coupling. Applied in our context, this method is excluded because we have to maintain the ecological character of the conduct. It was therefore necessary to find representative indicators of each experimental task, to measure the subjects' performance. In our experiments, we observe strong central nervous system plasticity, capable, within limits, to change the visual-haptic coupling, to adapt to a conflict, a noise or gain on either modality. These studies also make us perceive the added value of the haptic-related applications in the automotive industry.
